I guess the parameters are the fixed constants of nature. But there lies the problem. The Anthropic Principle is an unfalsifiable statement (aka. a tautology) that results from the “selection effect” of our own existence. Meanwhile, the fine-tuning argument is a surprising fact about the laws of nature as we know them.

It’s happening already, read this: “A theory of everything, a grand unified theory of physics and nature, has been elusive for the world of Physics. While unifying various forces and interactions in nature, starting from the unification of electricity and magnetism in James Clerk Maxwell’s seminal work A Treatise on Electricity and Magnetism [8] to the electroweak unification by Weinberg-Salam-Glashow [9-11] and research in the direction of establishing the Standard Model including the QCD sector by Murray Gell-Mann and Richard Feynman [12,13], has seen developments in a slow but surefooted manner, we now have a few candidate theories of everything, primary among which is String Theory [14]. Unfortunately, we are still some way off from establishing various areas of the theory in an empirical manner. Chief among this is the concept of supersymmetry [15], which is an important part of String Theory. There were no evidences found for supersymmetry in the first run of the Large Hadron Collider [16]. When the Large Hadron Collider discovered the Higgs Boson in 2011-12 [17-19], there were results that were problematic for the Minimum Supersymmetric Model (MSSM), since the value of the mass of the Higgs Boson at 125 GeV is relatively large for the model and could only be attained with large radiative loop corrections from top squarks that many theoreticians considered to be `unnatural’ [20]. In the absence of experiments that can test certain frontiers of Physics, particularly due to energy constraints particularly at the smallest of scales, the importance of simulations and computational research cannot be underplayed.”

Can a Computer Devise a Theory of Everything? (Published 2020)
“In the recent past, neural networks have also helped in determining heavy quarks as well as identifying electrons [76]. We can use deep learning to solve Schrodinger’s equation, to find the ground state energy [77]. There is a growing need to turn noisy and large data sets into meaningful information as we try to increase our ability to prepare and control increasingly complex quantum systems experimentally. It is in this area that we can utilize machine learning, such as the use of algorithmic learning and Bayesian methods for Hamiltonian learning [78], to classify quantum states [79] and to characterize unknown unitary transformations [80]. Reconstruction of the Hamiltonian to identify an accurate model for quantum system dynamics, extracting information on unknown quantum states and engineering quantum gates with pairwise interactions, using both time-independent and time-dependent hamiltonians, are all better done using artificial intelligence.”

“Time is related to the space coordinates, but they are not equivalent. Pythagoras’s theorem treats all coordinates on an equal footing (see Euclidean space for more details). We can exchange two space coordinates without changing the length, but we can not simply exchange a space coordinate with time: they are fundamentally different.
It is an entirely different thing for two events to be separated in space and to be separated in time. Minkowski proposed that the formula for distance needed a change. He found that the correct formula was actually quite simple, differing only by a sign from Pythagoras’s theorem:
Where c is a constant and t is the time coordinate.[Note 2] Multiplication by c, which has the dimensions L T â’1, converts the time to units of length and this constant has the same value as the speed of light.”
My question is: where does the negative sign come from ?”

Don’t let the below commenters put you off. Angular momentum is just as real for quantum particles, you just have to quantize it first. I like your idea, so do many very highly respected physicists.
you sure? “When an electron moves from a higher orbital to a lower orbital, the atom emits a photon. … Angular momentum is conserved only if there’s no external forces, in this case the electron gains energy by light or by heat wich is kinetic energy.”
Is the conservation of angular momentum violated in electron jumps from one orbital to another?
I don’t really know any quantum mechanics. But in our class, we were introduced to Bohr’s model of the atom with his postulate that the angular momentum of an electron in the $n$-th orbit is $frac...
Hmmm, i can see how a simplistic view of conservation of energy indicates that “the closer you get, the faster you go” but I think the analogy ends there. Electrons don’t even actually orbit the center of atoms, that was just a way to explain it, way back. Sorry.
I agree with the sentiment behind this idea. I mean, without cooperation you wouldn’t have anything to compete with. Including us. Read the article linked to, which states “Cooperation should dominate within an organization, while competition should dominate among organizations within a given social order. At the same time, there has to be a degree of cooperation among those organizations so that everyone is competing according to the same general rules.”

There is a good explanation of the idea here. Worth a read for those still perplexed by God playing dice. “To de Broglie, the double-slit experiment didn’t require an abstract, mysteriously collapsing wave function. Instead, he conceived of a real particle riding on a real pilot wave. The particle passes like driftwood through one slit or the other in the double-slit screen, even as the pilot wave passes through both. On the other side, the particle goes where the two wavefronts of the pilot wave constructively interfere and doesn’t go where they cancel out. “

Just found the response on Quora about a similar question, how philosophical and mathematical logic differ. I have pasted one answer below as it tickled me.
“When I was getting my PhD, we had a joint logic seminar with both philosophical and mathematical logicians. I would say the most striking difference is what part of the talk they are interested in.
When a mathematical logician gives a talk in front of an audience that contains philosophical logicians, it often goes something like this. There is a brief introduction, including a couple of definitions. For the mathematical logician, this is just boring routine stuff, something you need to go through before you write down the theorem and gets to the interesting part, the neat techniques he or she invented to prove it.
However, as soon as the definitions are shown, the philosophers raise their hands and want to discuss whether this is the “right” definition. For them, the definition is supposed to clarify what you are studying; the definition itself should captures some underlying basic truth. The mathematical logician just doesn’t care about that. He or she will rather be thinking something along the lines of “Clearly it is the right definition, because that is the definition that lets us prove this extremely cool theorem that I haven’t even gotten to write down yet! Shut up and let me get on with it!””

Physicists have spent decades trying to reconcile two very different theories. But is a winner about to emerge – and transform our understanding of everything from time to gravity?
Good point. Or any laws at all. “The good news is that string theory has no free parameters. It has no dials that can be turned. It doesn’t make sense to ask which string theory describes our universe, because there is only one.”

Scientists seek a single description of reality. But modern physics allows for many different descriptions, many equivalent to one another, connected through a

Sure does, its the ultimate giver and taker. I don’t think it gets enough credit. Maybe the idea of a 1-dimensional line with iron in the middle is a good way to represent it, even if it gives chemists the hump.
“The Atomic Number 26 is formidable. If there are 26 Protons and 26 Neutrons in the Atomic Nucleus, there is a perfect Balance between exchange of Photons and Gluons. Nature has somehow chosen the number 26 to be unbreakable.”
Why does iron not release energy in fusion or fission? I know it has to do with it having the least mass per proton/neutron, but why is it that way? - Quora
Wow, I so didn’t realise this was the case. So linking to where I landed when Googling it. On stack exchange, someone said this…
“Iron is a “special” element because of its nuclear binding energy. The very basic idea is that when you fuse two light elements together, you get a heavier element plus energy. You can do this up to iron. Similarly, if you have a heavy element that undergoes fission and splits into two lighter elements, you also release energy. Down to iron. You can see this in the plot shown in the wiki article I linked. The physical reason for this has to do with the balance between nuclear forces and the electromagnetic force.
Due to the way these energies work, and because iron is thus thought of as the most stable, if you want to get energy from fusion or fission, your best bet is to use atoms that are farthest away from iron — very light (like hydrogen) or very heavy (like uranium).
As a side note, this is also why Type 2 supernovae happen — the star can no longer gain energy from fusion because it can’t fuse past iron, so the outward pressure from energy generation stops and the star collapses.”
I remember reading something about how iron was a highly stable element. Ever since then, I have looked at iron fry pans with new-found respect. However, in a recent discussion I was unable to pinp...

“The governments of the various Italian city-states eventually grew frustrated by their citizens’ constantly shifting last names—without standardization, it was difficult to levy taxes or enforce military registration requirements. Beginning in Galileo’s lifetime, therefore, laws swept through Italy requiring parents to record both first and last names for their children. If a family had a traditional surname, they usually used that. If not, they resorted to town of origin or occupation, and then these names were passed down through the generations. “

Bet they didn’t realise at the time that the idea of the second law was what gives time a forward only direction. ie…”Entropy is one of the few quantities in the physical sciences that require a particular direction for time, sometimes called an arrow of time. As one goes “forward” in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease.”

Professor Mike Merrifield does a good job of explaining what this idea entails. The second law is the interesting one though, because it has various formulations as it was thought up before people understood entropy. Yes you need to add energy to a system in order to make colder things hotter. With regards to entropy, Lord Kelvin states that you can’t turn heat directly into useful energy. Seems obvious really but its an idea that has stood the test of time and likely won’t be disproven.
Penrose thinks that there is some real, physical “collapse” of a quantum superposition as objects grow big enough for gravity to become a significant part of the picture. Therefore: quantum mechanics might break down when confronted with gravity – when objects get big enough to “feel” significant gravitational force – so quantum mechanics needs modifying or reinterpreting.

Scientific American, making it sound like Carroll is the only guy to belive quantum mechanics is real and not just an idea: “Aim an instrument at the electron to determine where it is, and you’ll find it in just one place. You might reasonably assume that the wave function is just a statistical approximation of the electron’s behavior, which can’t be more precise because electrons are tiny and our instruments crude. But you would be wrong, according to Carroll. The electron exists as a kind of probabilistic blur until you observe it, when it “collapses,” in physics lingo, into a single position.”
Not sure if the OP of this idea understands the ins and outs of field theory and how quantum events can pop up out of non quantised fluctuations in the 19 or so fields we think we have discovered, but this video is a great introduction.

Interesting, in the description he says “Most entanglement videos discuss the concept just using Bell States, which were first discussed by Einstein, Podolsky, and Rosen, in their paper on the EPR Paradox. These states are special cases that allow us to understand what an entangled quantum state is most easily, but they aren’t the general case. I wanted to discuss the general case here, and what it specifically means to have an entangled state.”

Unfortunately, scientists are not any closer to observing dark matter, given that they don’t even know the type of particles they should be looking for.
This Is The Real Reason We Haven't Directly Detected Dark Matter
Time doesn’t really exist, its just an emergent phenomenon we believe we percieve – according to Julian Barbour. Well, that’s his solution to the problem of time in physics and cosmology. Yep it’s as simply stated as it is radical.
Giving a name to something you don’t know is there is a risky business, people will believe it before it has been observed. Is this idea based on science or something else?
Entropictastic! “Dark energy could be merely mimicking the cosmological constant, a scalar field changing so slowly that we have not yet been able to detect it. Or (whisper it quietly) perhaps dark energy does not even exist.”
20 years after discovering that the universe is expanding with increasing speed, scientists still argue about whether dark energy explains it. Keith Cooper explores the debate
I think Sean is doing us all a major favour by pushing this idea in order to help us start asking the right questions again. Bless him if he doesn’t even fully â€believe’ in many worlds, but is championing it at risk of being a fall-guy for the benefit of future generations of physicists. For this, he needs a stack of medals. And yes, giving credit to Everrett makes him seem respectful for ousted thinkers of the past – but he has a difficult task in explaining many worlds to layman, like me, without confusing us by adding the maths. (Btw America, unlike the universal wave function there is more than just one math).
Why hasn’t he convinced my confused but open mind yet? Well, after watching and listening to everything I can find that he works tirelessly to put out (including the BBCs infinite monkey cage that just added more woo) and especially his fab great courses plus series on time (actually it was about entropy, but hey…) I talked to a bunch of people and many get “stuck” on the same handful of points he raises. None of us could find answers to a few things he states time and again, without actually explaining them in a way that resolves our questions – for example:
1 – Maybe entangled electrons are just like a pair of socks. You know, one is a righty so you can infer the other is a lefty – without any information travelling spookily. If this isn’t the case, I need to know which experiment actually shows they are undecided wave functions before they collapse into left or right (or spin up and down)?
2 – Different worlds that “don’t talk to each other” is a phrase he uses a lot but that is just a phrase, he doesn’t describe what this really means, like the Copenhagen interpretation it glosses over without giving a satisfactory explanation, just a soundbite, no? and if the world splits rather than makes new worlds, wouldn’t it already be thinner than the equivalent of a â€many worlds’ plank length already. How far can this actually go without sharing out all the universe’s energy?
3 – He explains how the observation problem is totally misunderstood because people think it involves humans observing things, which will cause the wave function to collapse, ie decoherence. He explains that any particle of light or matter, or whatever, that can â€sense’ where a particle is (or which way it is spinning for example), is enough to count as an observation. However, I have problems understanding when it is that light or matter DOESN’T sense another particle’s spin or position. Ie when is it where a wave function doesn’t collapse? Maybe he means only light that has never landed on something? (yet).
I would love him to take 5 minutes out to answer these as I am “in” if he can explain what he means properly without going into Hawking mode and just clicking the same phrases out again and again. However, I don’t think a couple of tweets would do the job.
Too shy to ask but if anyone can shed any â€light’, on this â€matter’ let me know. I will keep following his every word to see if he goes into more detail without adding maths. If you ever get to talk to him, thank him for all the hard work and inspiration. PS that blasted cat is surely an x cat now – stop flogging it in universities, just admit you don’t know the answers, thats what everyone else does, surely a university would be the first to express this, its what inspires new minds to come up with new ideas.

Regenerative braking is a cool technology that allows you to charge your electric car from the braking force.
Even if scientists managed to build a space elevator, the risks of such a structure (for example, a collapse due to a terrorist attack or natural disaster) would still be too high.
Building a space elevator presents so many technical challenges that we might not see one in our lifetime.
This company that has been researching a lunar space elevator that could be potentially used to colonize the moon. https://www.liftport.com/
The space elevator idea is a pretty old concept; it was first conceived in the 19th century. Unfortunately, we are still far off from making this dream a reality.
Space elevators are among the most popular tropes in sci-fi movies and TV shows. A real one could potentially change humanity’s future.
Even if faster-than-light travel was invented, it would still be impossible to travel back in time.
You could potentially time travel if you traveled faster than the speed of light. However, such technology doesn’t exist and it is unlikely it will.
We are always traveling into the future – but in real time.
Time travel is a fantasy concept mostly based on movies and TV shows. Sadly, many of the theories obey the existing laws of physics.

Thanks Ed Witten and the rest. All that meaning and order, being broken down into tiny fragments of truth, that you now can’t reconsider. Great stuff, chaos and calmness are nigh.
Physics is broken again. Spending our money and brains when we could be unravelling life and consciousness. When will mechanics stop fiddling and allow the rest of us the resources we need to unlock the mystery of evolution and our minds as we rise to the heavens?
It’s not right (yet) though as they say, superstring theory is not even wrong. Here Witten admits its been a longer journey to disprove his theory than he thought it would. Heh.
It has to be right – because anyone can change it to suit pretty much ANY future finding – not really science but an answer all the same
Trust physicists to make a simple concept difficult.
Such a weird concept, transforming something so it’s the same – not everything can do that. Great vid here btw.
Ahh, yes,. the idea of symmetry – changing something but keeping it the same. Not an obvious feature of the universe until you get curious. Great site about it here https://devdude.me/blog/physSymmetries
Nothing matters, only if you think the judgement comes at the end of life, rather than throughout each day. Anyways, look at this nice picture someone made about it.
Nothing matters. Nihil!
Physics jokes rock!
“The world was made with time, not in time.” – Augustine said that before any cosmologist.
DNA as in it’s unique fingerprint, But if you change a little bit the laws of nature, or you change a little bit the constants of nature—like the charge on the electron—then the way the universe develops is so changed, it is very likely that intelligent life would not have been able to develop.
The DNA of the universe are the parameters that govern its laws
(3 upvotes)Cosmological Natural Selection
(1 upvotes)this is kinda irrelevant, but interesting anyways… https://www.space.com/2157-cosmic-dna-double-helix-spotted-space.html
I recommend you read this – not being rude but there seems to be more to it. I didn’t understand everything the author claimed but there is plenty of evidence that there is some fine-tuned DNA-like evolution going on somewhere up there.
I guess the parameters are the fixed constants of nature. But there lies the problem. The Anthropic Principle is an unfalsifiable statement (aka. a tautology) that results from the “selection effect” of our own existence. Meanwhile, the fine-tuning argument is a surprising fact about the laws of nature as we know them.
Don’t believe the dictionary or any POP SCI GUY who don’t get what it is. Entropy is a measure of the amount of hidden or missing information contained in a system, not a measure of the amount of available or unavailable energy.
And this by Nick Lucid.
Yes, it’s a bit of a cheesey buzzword in science at the moment but this is the best video I can think of that describes entropy well.
Yawn, no. entropy is now just a quantum buzzword.
…and out pops spacetime, geddit Lex?
Posting the video mentioned by the OP – Kepler’s laws nailed, then, then, then… This is getting exciting again since recent quantum guys broke physics for us all.
Let Lex mumble through it for you. Great interview though. Answer, yes they can, and likely will discover all the bits we failed to solve.
I think they could do it, but would they even let on, or keep us in suspense for their own means – They may know something we don’t already
Love the line in this video “Our journey from perfection to corruption” = broken synergy over time
In physics, AI is being used to analyze data from experiments and simulations, as well as to develop new models and theories. AI can also be used to find new patterns and correlations in data that were previously hidden, allowing physicists to make new discoveries. Why shouldn’t Artificial Intelligences share the answers with humans? Hidden information is just as valid as information you can all access and use – why not just hope they keep the answers secret from mankind, rather than just destroy humanity – ie, kill people for it, like humans tend to do when frustrated or lacking the right information or required energy?
Dirac was a Genius, he would love youtube https://www.youtube.com/watch?v=9IpNEzucNyo maybe, heh 🙂
Watch this…
They may be variable, or just the constants of nature could be variable, that could lead to what we have today.
I can change the laws of physics whenever I fancy, but cannae change the laws of nature, which they try to describe – so sorry wee Jimmy, you’re wrong.
entropy cannot be destroyed by any means at any scale – sorry!

A simple but excellent idea that can transform a community, especially in rural areas.
It’s happening already, read this: “A theory of everything, a grand unified theory of physics and nature, has been elusive for the world of Physics. While unifying various forces and interactions in nature, starting from the unification of electricity and magnetism in James Clerk Maxwell’s seminal work A Treatise on Electricity and Magnetism [8] to the electroweak unification by Weinberg-Salam-Glashow [9-11] and research in the direction of establishing the Standard Model including the QCD sector by Murray Gell-Mann and Richard Feynman [12,13], has seen developments in a slow but surefooted manner, we now have a few candidate theories of everything, primary among which is String Theory [14]. Unfortunately, we are still some way off from establishing various areas of the theory in an empirical manner. Chief among this is the concept of supersymmetry [15], which is an important part of String Theory. There were no evidences found for supersymmetry in the first run of the Large Hadron Collider [16]. When the Large Hadron Collider discovered the Higgs Boson in 2011-12 [17-19], there were results that were problematic for the Minimum Supersymmetric Model (MSSM), since the value of the mass of the Higgs Boson at 125 GeV is relatively large for the model and could only be attained with large radiative loop corrections from top squarks that many theoreticians considered to be `unnatural’ [20]. In the absence of experiments that can test certain frontiers of Physics, particularly due to energy constraints particularly at the smallest of scales, the importance of simulations and computational research cannot be underplayed.”
Steven Weinberg, called it “a troubling thought” that humans might not be smart enough to understand the final Theory of Everything. “But I suspect in that case,” he wrote in an email, “we will also not be smart enough to design a computer that can find a final theory.” — MORE HERE https://mindmatters.ai/2020/12/can-a-powerful-enough-computer-work-out-a-theory-of-everything/

One of the reasons A.I. has been so successful at solving games,” Dr. Thaler said, “is that games have a very well-defined notion of success.” He added, “If we could define what success means for physical laws, that would be an incredible breakthrough.

“In the recent past, neural networks have also helped in determining heavy quarks as well as identifying electrons [76]. We can use deep learning to solve Schrodinger’s equation, to find the ground state energy [77]. There is a growing need to turn noisy and large data sets into meaningful information as we try to increase our ability to prepare and control increasingly complex quantum systems experimentally. It is in this area that we can utilize machine learning, such as the use of algorithmic learning and Bayesian methods for Hamiltonian learning [78], to classify quantum states [79] and to characterize unknown unitary transformations [80]. Reconstruction of the Hamiltonian to identify an accurate model for quantum system dynamics, extracting information on unknown quantum states and engineering quantum gates with pairwise interactions, using both time-independent and time-dependent hamiltonians, are all better done using artificial intelligence.”

Just dropping this here as Lucid makes it very clear, as usual.
It’s the most suitable word IMO. It resembles the meaning of spin people already understand. From this article “”Spin is the total angular momentum, or intrinsic angular momentum, of a body. The spins of elementary particles are analogous to the spins of macroscopic bodies.”
It would be cool if electrons spun like these guys though.

I agree with some of those on quora that say maths is fundamental and various universes keep popping into it. Don’t care if it is demonstratable or not, it stands to reason. But unsure AI will be needed to prove anything, to what is left of us once it starts answering its own questions.
People trust math like they trusted god. It’s going a full circle.
Or is this just a math trick to get us out of the quantum problem? Not a great idea if you ask me.
From a Quora answer: Contrary to the (very) popular belief, the Planck length has not been proven to be the smallest possible unit of space. But yes, it is a good IDEA, so was the idea of atoms and waves, once.
Just when you thought you “got it”…
but… “If all of the platonic world is contained within some of the mental world, all of the mental world is contained is some of the physical world and all of the physical world is contained within some of the Platonic something is broken!”

if its for quantum physics demonstrations, you could have perpetual motion machines, probably. at least until it heats up and dies, like everything else đź‰
like this idea. some sort of logic gate run for small balls.
“Time is related to the space coordinates, but they are not equivalent. Pythagoras’s theorem treats all coordinates on an equal footing (see Euclidean space for more details). We can exchange two space coordinates without changing the length, but we can not simply exchange a space coordinate with time: they are fundamentally different.
It is an entirely different thing for two events to be separated in space and to be separated in time. Minkowski proposed that the formula for distance needed a change. He found that the correct formula was actually quite simple, differing only by a sign from Pythagoras’s theorem:
Where c is a constant and t is the time coordinate.[Note 2] Multiplication by c, which has the dimensions L T â’1, converts the time to units of length and this constant has the same value as the speed of light.”
My question is: where does the negative sign come from ?”
its more than an idea, but i guess it was an idea before it was an equation. Brian Cox does well explaining this here https://www.youtube.com/watch?v=GkCWywO93b8
…. as mentioned in a “closer to truth” youtube video.
Angular momentum, in the form of “spin” is transferred to or from the photon. but read this to get a better idea of what you are trying to say… https://www.thenakedscientists.com/forum/index.php?topic=35361.0
Don’t let the below commenters put you off. Angular momentum is just as real for quantum particles, you just have to quantize it first. I like your idea, so do many very highly respected physicists.
you sure? “When an electron moves from a higher orbital to a lower orbital, the atom emits a photon. … Angular momentum is conserved only if there’s no external forces, in this case the electron gains energy by light or by heat wich is kinetic energy.”
Hmmm, i can see how a simplistic view of conservation of energy indicates that “the closer you get, the faster you go” but I think the analogy ends there. Electrons don’t even actually orbit the center of atoms, that was just a way to explain it, way back. Sorry.
I agree with the sentiment behind this idea. I mean, without cooperation you wouldn’t have anything to compete with. Including us. Read the article linked to, which states “Cooperation should dominate within an organization, while competition should dominate among organizations within a given social order. At the same time, there has to be a degree of cooperation among those organizations so that everyone is competing according to the same general rules.”
good god, didn’t know they could “do” this. They need lessons from ant brains though.
Here is the video I mentioned in the original ideas. IdeaMill should make links in ideas into previews, the way they are in links.

good point. good ideas get hidden by the ole boys club for sure, reminded me of this video from a while back https://www.youtube.com/watch?v=WG0XVDiwrVE
Theoretical physics means you invent answers and spend your life looking for them. Ironically it works better than the old way of waiting to find something when you don’t know what you are looking for.
“give up and let theorists just tell their stories?” lol, sounds about right.
“To date, no evidence for supersymmetry has been found, and experiments at the Large Hadron Collider have ruled out the simplest supersymmetric models.” Just sayin’
Glad it appears on ideamill – ITS JUST AN IDEA, NOT A THING, watch this.
PBS Spacetime is always the best place to get an understanding of our faulty understanding of quantum mechanics. Watch this. the mystery is far from over and like Dirac indicated, new ideas are here needed. Lets hope the next generation will solve this for us as its been annoying some very clever people for well over a century now.
There is a good explanation of the idea here. Worth a read for those still perplexed by God playing dice. “To de Broglie, the double-slit experiment didn’t require an abstract, mysteriously collapsing wave function. Instead, he conceived of a real particle riding on a real pilot wave. The particle passes like driftwood through one slit or the other in the double-slit screen, even as the pilot wave passes through both. On the other side, the particle goes where the two wavefronts of the pilot wave constructively interfere and doesn’t go where they cancel out. “
Adding the video as a link so you can see it.
Just found the response on Quora about a similar question, how philosophical and mathematical logic differ. I have pasted one answer below as it tickled me.
“When I was getting my PhD, we had a joint logic seminar with both philosophical and mathematical logicians. I would say the most striking difference is what part of the talk they are interested in.
When a mathematical logician gives a talk in front of an audience that contains philosophical logicians, it often goes something like this. There is a brief introduction, including a couple of definitions. For the mathematical logician, this is just boring routine stuff, something you need to go through before you write down the theorem and gets to the interesting part, the neat techniques he or she invented to prove it.
However, as soon as the definitions are shown, the philosophers raise their hands and want to discuss whether this is the “right” definition. For them, the definition is supposed to clarify what you are studying; the definition itself should captures some underlying basic truth. The mathematical logician just doesn’t care about that. He or she will rather be thinking something along the lines of “Clearly it is the right definition, because that is the definition that lets us prove this extremely cool theorem that I haven’t even gotten to write down yet! Shut up and let me get on with it!””
Philosophical and mathematical – but they are really the same thing. however there is a difference in how they are taught and used. From stack exchange… “The main difference between “Logic in Philosophy” and “Mathematical Logic” is that in the former case logic is used as a tool, while in the latter it is studied for its own sake.”
I blame Spock. Mr, not Dr. Fake news at the most fundamental level.
Hmm, I thought this was a silly idea, but I just read on Wikipedia otherwise. That “In mathematics and logic, a higher-order logic is a form of predicate logic that is distinguished from first-order logic by additional quantifiers and, sometimes, stronger semantics.”
Aha! But according to another idea on Ideamill, your head has travelled further than your feet – and moving through space also warps spacetime – so maybe it evens up?
In that case, the question still stands: from the head’s perspective has it REALLY lived longer than the feet, AND from the feet’s perspective have they REALLY lived longer than the head.
OMG. These silly “science” writers just love throwing wormholes in to the equation – but the nature of the Universe is amazing enough without having to sex it up with crappy conjecture. When will we learn?
Love this pic, didn’t read the article though.
We are only here discussing the idea of the Sun’s gender because it does so well at providing us the perfect environment for us to live and prosper. However, The solar genitals are not what matter, nor how (s)he identifies. Because regardless of its sexuality THE SUN WILL SPAWN OFFSPRING, and had parents – which is all that matters. Is he or she trans or gay or both? Or are we just doing the usual human thing of applying our ideas to the wrong things?
Lol, thanks for spending our money wisely NASA “We’ve been working on this ever since Neil Armstrong found out the Moon was a boy back in â€69” said Dr. Andrew Chapner of NASA’s Star Gender division. “And look, we know it’s not our business how the Sun identifies but we just have to know.”
For most Sol is a female (word) for the Germans, not so. But I get your point, it protects and nourishes us, so a bit of both.
CONGRATULATIONS! IT’S A GIRL!
Posting this link becuase it’s good read. “Current ideas about memories are far from watertight – for example, that they are stored in the architecture of neuron networks or in the junctions between neurons. “My gut instinct is that neuroscience has lots of things that remain puzzling,” says Fisher. So why not see if there are better quantum explanations?”
Lol, because we understand neither, we put them together so that’s one less thing to worry about. The double-slit experiment has lots to answer for!
Read this, if you can get through it. It’s worth it – probably đź‰
Never heard of this idea before but yeah… since quantum theory is the most fundamental theory of matter that is currently available, it is a legitimate question to ask whether quantum theory can help us to understand consciousness. Relativity didn’t help with that.
Will time stop? Depends if Stephen Hawkin was right… It now appears the entire cosmos is living on borrowed time. It may be a blip within a much grander sweep of time. We now ask, will time end?
Research from the University of Maine said: “Time dilates on moving vessels: the greater the speed, the greater the time dilation. Only when such velocities approach light speed do such effects become significant.
“If, and this one of those extreme IF’s, a vessel could attain light speed, time aboard the vessel would cease altogether.
Didn’t realise this existed, nice tool.
Watch this for context on the sword. PS, killed many people once he got power from parliament, and died a virgin. Just sayin’
looks like a particle to me. I think it is a particle and a wave. So do most that read physics.
There are 2 currently, and they don’t mix but so what? Who says they should fit each other. I get you. In one situation one set of laws wins, in another the other does. Just like jurisdiction in criminal laws and rules in languages. Scientists are intent on reductionalism at all costs but the Universe may not be that simple. And it evidently isn’t.
Alpha, may give us a lawless universe.
Good point. Or any laws at all. “The good news is that string theory has no free parameters. It has no dials that can be turned. It doesn’t make sense to ask which string theory describes our universe, because there is only one.”
The laws of physics are just very compact restatements of everything that happens in the universe

Thought I had found one online then but this thing just identifies the source of the radiation.
Sure does, its the ultimate giver and taker. I don’t think it gets enough credit. Maybe the idea of a 1-dimensional line with iron in the middle is a good way to represent it, even if it gives chemists the hump.
“The Atomic Number 26 is formidable. If there are 26 Protons and 26 Neutrons in the Atomic Nucleus, there is a perfect Balance between exchange of Photons and Gluons. Nature has somehow chosen the number 26 to be unbreakable.”
I got this quote from Quora. https://www.quora.com/Why-can-elements-heavier-than-iron-only-undergo-fission-whilst-elements-lighter-than-iron-can-only-undergo-fusion
Wow, I so didn’t realise this was the case. So linking to where I landed when Googling it. On stack exchange, someone said this…
“Iron is a “special” element because of its nuclear binding energy. The very basic idea is that when you fuse two light elements together, you get a heavier element plus energy. You can do this up to iron. Similarly, if you have a heavy element that undergoes fission and splits into two lighter elements, you also release energy. Down to iron. You can see this in the plot shown in the wiki article I linked. The physical reason for this has to do with the balance between nuclear forces and the electromagnetic force.
Due to the way these energies work, and because iron is thus thought of as the most stable, if you want to get energy from fusion or fission, your best bet is to use atoms that are farthest away from iron — very light (like hydrogen) or very heavy (like uranium).
As a side note, this is also why Type 2 supernovae happen — the star can no longer gain energy from fusion because it can’t fuse past iron, so the outward pressure from energy generation stops and the star collapses.”
Hmm, I like this idea but I wonder what it means inside a black hole, if time becomes space. I mean. if time really does become space then there is no “when” right? and therefor this is a region where the Universe doesn’t have events, interactions and possibly any meaning. Confused.com doesn’t help here 🙂
I bet Sean Carroll has this game ready for the next lock-down.
Entropy may not be what it used to be, but order can come back to where it once was. As above, so below. So it goes!
Want!
No such thing as a closed system. That’s a spherical cow, physicists milk due to their thirst for knowledge. Cheers!
Law isn’t order – Anarchy isn’t chaos – Entropy isn’t disorder. Stop over-simplifying things. Check the entropy site if you want to get all heated up about it. How cool is this?
Me: when did entropy begin? Google/Wikipedia: In the 1850s.
Some people try to encourage people to call them by a single name still, to strengthen their brand. It usually doesn’t work (Opera, Dubya) but Bjork managed to get away with it. Interesting selection of people. not as interesting as Galilee though.
….and Tycho, and possibly even Homer, if he was a person (rather than just a name that was used to attribute stories of many authors to.) Seems like folk will call you what you call yourself.
This article explains his name, but you are gonna have problems getting everyone else to start naming him by his last name.
“The governments of the various Italian city-states eventually grew frustrated by their citizens’ constantly shifting last names—without standardization, it was difficult to levy taxes or enforce military registration requirements. Beginning in Galileo’s lifetime, therefore, laws swept through Italy requiring parents to record both first and last names for their children. If a family had a traditional surname, they usually used that. If not, they resorted to town of origin or occupation, and then these names were passed down through the generations. “
More from Rovelli in his lecture. Very hard to disagree with and nice to see someone pushing the boundaries in a way that makes people look at things in a slightly different way. It’s still physics, but not as we know it Jim.
Not sure if this is the original idea but its mentioned by Carlo Rovelli in a Closer To Truth video.
Sick to death of this “spooky” shit. Get over it.
Rovelli really is your guy for this – I highly recommend his book where he convinced me that yep, events and not objects are the fundamental reality. Objects are so one dimensional after you have read this, I will never go back to my old way of thinking – he is a great explainer. Buy it and say goodbye to the silly old world of objects.
… and the longest wouldn’t move at all…
I searched to see if this idea is right but can’t find an answer. I guess in practice you couldn’t have a infinitesimal length pendulum but in theory maybe you could. Anyways, I found this, which made sense, just doesn’t answer my question. Is this idea silly or a good way to practice physics and maths thinking?
VSauce should sell quantum dice rather than the regular magic 8 ball you get in his pack of goodies – seen in this video he did.
Give me a lever long enough and I can move the world. I guess this works backwards too. nice idea.
Crazy-rude idea – will probably be a real thing pretty soon. Watch this space! Well, you can’t see a space but you know what I mean – Watch this invisible thing, if you can see it.
Thank goodness, wouldn’t want 4Ă—10^84 photons tickling my brain.
Aptly named book about science that ‘stares you in the face’.
This – maths and physics versus the real world
Aha! Nice new angle on the spherical (sacred) cow, idolised (idealised) by physicists. Here SHE is.
Earth, the sun, and countless other bodies in the universe are irregular ellipsoids, its unreal that these shapes/objects don’t get the coverage of the ‘stars’ of geometry.
Spheres are so 2020.
Someone should buy this so he can sit down.
Probably inspired by Matt Parker’s introduction to ellipsoids video. Still very regular, but not sure how the physicists would cope with the idea of ellipsoid cows.
IS the Universe a closed system? How could you disprove that it isn’t? Too many assumptions in order to KNOW the second law is ALWAYS right (for me).
Time will tell….. “Physicists at the University of Zurich have developed a deceptively simple device that allows heat to flow temporarily from a cold object to a warm object without an external power supply.”
Don’t hold your breath. If this new theory pans out, quantum demons might someday power our air conditioners and refrigerators, saving you electricity and cheating the current laws of physics at the same time.
nice idea, but the jury is still out on if it is the reason time goes one way only, everything else points to it being able to go both ways, just not for urr, us.
Bet they didn’t realise at the time that the idea of the second law was what gives time a forward only direction. ie…”Entropy is one of the few quantities in the physical sciences that require a particular direction for time, sometimes called an arrow of time. As one goes “forward” in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease.”
Professor Mike Merrifield does a good job of explaining what this idea entails. The second law is the interesting one though, because it has various formulations as it was thought up before people understood entropy. Yes you need to add energy to a system in order to make colder things hotter. With regards to entropy, Lord Kelvin states that you can’t turn heat directly into useful energy. Seems obvious really but its an idea that has stood the test of time and likely won’t be disproven.
Penrose thinks that there is some real, physical “collapse” of a quantum superposition as objects grow big enough for gravity to become a significant part of the picture. Therefore: quantum mechanics might break down when confronted with gravity – when objects get big enough to “feel” significant gravitational force – so quantum mechanics needs modifying or reinterpreting.
Electromagnetically induced transparency – watch this space… not as daft as it sounds… “
The next Einstein, and Wheeler, need to think SMALL…
Was a great idea… til quantum mechanics.
Gravity isn’t a force, and Einstein was wrong – just still the best explanation we have at the moment.
Can it uncurve though? I guess you would need something with negative mass in order to flatten it back out again, no?
“atoms” came before “matter” idea, so linking back to this as they are related,

OMG it’s worse than that, we’re dead Jim – “The Multiverse Idea Is Rotting Culture”
This is a universe whose components eventually assembled themselves in such a way that they would turn around, look at themselves, and try to understand how they and their universe had been created; a universe whose building blocks would become intelligent.
Someone’s making Billions and Billions.
It’s SCIENCE jim, but not as we KNOW it.
Sagan gave up hope and accepted despair to remain true to bad philosophy.
Like the idea, but it would be hard to animate what an atom REALLY looks like.
Great idea, I could watch this all day, especially if it went from hydrogen up through all the elements – without it being part of a narated documentary. But better would be those animations of cells and machines in the body seen in this video. Anyone know where on youtube has this type of animation with no sciency bits to learn?
Carl habitually conveyed false depictions of what indeed is skepticism; conflating it in the quote below with cynicism and completely missing the fact that skepticism involves precisely an active, researching and open mind. Pretending that possessing an open mind is somehow the opposite of skepticism, and involves giving all ideas â€equal validity.’
Well I hope he doesn’t get in touch with us…. heh
Maybe the universe designed itself after some “fine-tuning”. READ THIS https://link.springer.com/article/10.1007/s11153-018-9692-z
Atoms have intelligence – now there’s a major idea in itself.
“In this article the author attempts to explain a theory that states that reality is a “self aware, self conscious construct, aka it is intelligent.” Through a discussion starting with the birth of reality from quantum foam deciding its own set of laws all the way to the neurons in our brains and their constituent atoms, the author states that atoms are information processors since the brain is an information processor. And as such, atoms have a real (although extremely low level) form of intelligence.”
Scientific American, making it sound like Carroll is the only guy to belive quantum mechanics is real and not just an idea: “Aim an instrument at the electron to determine where it is, and you’ll find it in just one place. You might reasonably assume that the wave function is just a statistical approximation of the electron’s behavior, which can’t be more precise because electrons are tiny and our instruments crude. But you would be wrong, according to Carroll. The electron exists as a kind of probabilistic blur until you observe it, when it “collapses,” in physics lingo, into a single position.”
There is nothing but fields. Maybe …. Carrol is the best guy to explain this
Not sure if the OP of this idea understands the ins and outs of field theory and how quantum events can pop up out of non quantised fluctuations in the 19 or so fields we think we have discovered, but this video is a great introduction.
never thought about it before but yep, if it wrapped round from one side to the other, you could easily see that they just build up and up with atomic mass.
You are not alone with this idea. it needs work for sure…

Genius. Penrose always explains things so well – why make it more confusing with many worlds when you can have just the 1 we know and love?
Interesting, from Quora:
“The mathematical version of the butterfly effect is easy to test. Some mathematical systems are chaotic and a trivial change in initial conditions will lead to large changes in the result. An example is the logistic difference equation
xn+1=rxn(1â’xn)
In physical systems, the double pendulum is an example of a chaotic system, and very small changes in initial conditions lead to large changes in behavior.”
The idea of chaos theory as a thing-in-itself seems to have died an early death.
Manyworlds is a trick of the mind – disputed and pretty much debunked in his own podcast.

It is true that the Serapeion does seem to have been used at one point to house some of the books from the Library of Alexandria’s collection, but….. “

Interesting idea, and to be honest, hard to disprove.
Interesting, in the description he says “Most entanglement videos discuss the concept just using Bell States, which were first discussed by Einstein, Podolsky, and Rosen, in their paper on the EPR Paradox. These states are special cases that allow us to understand what an entangled quantum state is most easily, but they aren’t the general case. I wanted to discuss the general case here, and what it specifically means to have an entangled state.”
Bell Test debunked – they are not entangled – its not that seeing one glove makes the other’s wave function collapse, just that if this one is a right hand glove, then the other is known to be a left hand glove – no spooky action, no magic, get over it.
child’s play…
“According to this theory, the universe can be conceived of as either the output of a deterministic or probabilistic computer program, a vast, digital computation device, or mathematically isomorphic to such a device.”
Interesting idea, questions and answers – information entropy will be the ultimate fate of the Universe mark (then lose) my words

It is true that our particular form of life would have been impossible without “fine tuning” of the universe’s structure, but we do not know if there could have been equally fine-tuned, yet fantastically different universes supporting biological life. Anthropic principles fail to explain why our universe is in one such fine-tuned state, when “all things being equal”, it was much more likely to develop into chaos.
Don’t trust those on Quora who try to help out but don’t think things through. Your eye can’t touch or reach the matter it is looking at, it can sense the light that travels to it from the object made of matter.
Yep, I guess if you can’t see atoms, then you can’t see matter. Never thought of it that way but yeah, all is light. weird.
NYU says you can – but then they are explaining things to those who don’t have much knowledge – so keeping it simple…
Khan Academy also cover it. So fundamental, its easy to miss completely before getting into more complex physical ideas
Here is the Q and A Carroll published a few days later. Goes into more detail on some points. He is a great explainer – just what we need right now – especially in confused qm physics.
Great video, explains a lot and I didn’t realise it but yeah, conservation of momentum and energy are great ideas it would take a while to fully getting to grips with.
People use the anthropic principle to argue that the Universe must be exactly as it is because we exist the way we do. And that’s not only untrue, it’s not even what the anthropic principle says.
Infogram should make them so you click a segment of the pie and it takes you to another full pie. That would do the trick.
You can use a few more options, like light, rare, and airy, but none are satisfying or as accurate as “less dense”.

I found this paper on these four great ideas of biology. It is a great read!
https://pmc.ncbi.nlm.nih.gov/articles/PMC4952585/
Check out this video, which summarises a few more big ideas of biology.
Unfortunately, scientists are not any closer to observing dark matter, given that they don’t even know the type of particles they should be looking for.
Check this out! Some scientists have an alternative theory that dark matter may not exist.
https://theconversation.com/dark-matter-may-not-actually-exist-and-our-alternative-theory-can-be-put-to-the-test-110238
This is quite true! Dark matter is still a hypothesis at this stage.
Interesting, as Einstein once said: “Time and space are modes by which we think, and not conditions in which we live”
Time doesn’t really exist, its just an emergent phenomenon we believe we percieve – according to Julian Barbour. Well, that’s his solution to the problem of time in physics and cosmology. Yep it’s as simply stated as it is radical.
Giving a name to something you don’t know is there is a risky business, people will believe it before it has been observed. Is this idea based on science or something else?
Entropictastic! “Dark energy could be merely mimicking the cosmological constant, a scalar field changing so slowly that we have not yet been able to detect it. Or (whisper it quietly) perhaps dark energy does not even exist.”
I think Sean is doing us all a major favour by pushing this idea in order to help us start asking the right questions again. Bless him if he doesn’t even fully â€believe’ in many worlds, but is championing it at risk of being a fall-guy for the benefit of future generations of physicists. For this, he needs a stack of medals. And yes, giving credit to Everrett makes him seem respectful for ousted thinkers of the past – but he has a difficult task in explaining many worlds to layman, like me, without confusing us by adding the maths. (Btw America, unlike the universal wave function there is more than just one math).
Why hasn’t he convinced my confused but open mind yet? Well, after watching and listening to everything I can find that he works tirelessly to put out (including the BBCs infinite monkey cage that just added more woo) and especially his fab great courses plus series on time (actually it was about entropy, but hey…) I talked to a bunch of people and many get “stuck” on the same handful of points he raises. None of us could find answers to a few things he states time and again, without actually explaining them in a way that resolves our questions – for example:
1 – Maybe entangled electrons are just like a pair of socks. You know, one is a righty so you can infer the other is a lefty – without any information travelling spookily. If this isn’t the case, I need to know which experiment actually shows they are undecided wave functions before they collapse into left or right (or spin up and down)?
2 – Different worlds that “don’t talk to each other” is a phrase he uses a lot but that is just a phrase, he doesn’t describe what this really means, like the Copenhagen interpretation it glosses over without giving a satisfactory explanation, just a soundbite, no? and if the world splits rather than makes new worlds, wouldn’t it already be thinner than the equivalent of a â€many worlds’ plank length already. How far can this actually go without sharing out all the universe’s energy?
3 – He explains how the observation problem is totally misunderstood because people think it involves humans observing things, which will cause the wave function to collapse, ie decoherence. He explains that any particle of light or matter, or whatever, that can â€sense’ where a particle is (or which way it is spinning for example), is enough to count as an observation. However, I have problems understanding when it is that light or matter DOESN’T sense another particle’s spin or position. Ie when is it where a wave function doesn’t collapse? Maybe he means only light that has never landed on something? (yet).
I would love him to take 5 minutes out to answer these as I am “in” if he can explain what he means properly without going into Hawking mode and just clicking the same phrases out again and again. However, I don’t think a couple of tweets would do the job.
Too shy to ask but if anyone can shed any â€light’, on this â€matter’ let me know. I will keep following his every word to see if he goes into more detail without adding maths. If you ever get to talk to him, thank him for all the hard work and inspiration. PS that blasted cat is surely an x cat now – stop flogging it in universities, just admit you don’t know the answers, thats what everyone else does, surely a university would be the first to express this, its what inspires new minds to come up with new ideas.
Many worlds has many problems, not quite debunked but not understood either.
Just doesn’t cut it for me, I mean inventing more universes just to solve a small problem in our own seems like a cop out… and this is exactly the type of false solution we should avoid falling into, maybe just admit we don’t know the answer yet?

Great idea, but nobody knows why gravity only sucks, see the new scientist article here https://www.newscientist.com/article/mg20227122-800-gravity-mysteries-why-does-gravity-only-pull/
Sean Carroll’s take on what is wrong with QM and why he believes many worlds is the simplest explanation of why physics has been barking up the wrong tree for almost a century. To be fair, it explains a lot but not everything we need to know in order to make progress.
Dark energy has been accelerating the expansion of the universe for a while. Unfortunately, this could ultimately cause the universe to tear apart.
It’s obviously dark energy! The expansion of the universe is a tug-of-war between dark matter and dark energy, with dark energy winning.
Since dark energy is three times more than dark matter, it’s pretty clear which one is winning.
