Our moon is the nearest space object to us and for this reason, it has been a main and first concern of the astronomers. Many probes were sent to the artific...
NASA is looking for a durable sun-independent energy source to produce tens of kWs for NASA missions on the moon by the end of the decade – in other words a small nuclear reactor.
He retired to Cumbria empty-handed bless him. Though he coined the term BIG BANG by accident and thought it was a load of rubbish. Crawl back under your rock Hoyle, there’s nothing for you here!
As the winners of this year’s Nobel science prizes are about to be announced, Robin McKie looks back at the controversial life of groundbreaking scientist Fred Hoyle
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 photo first appeared in the The Vidette-Messenger of Valparaiso, Indiana on August 5, 1948. The children looked posed and a bit confused as their pregnant mother hides her face from the photogr…
A movement of women have decided not to procreate in response to the coming ‘climate breakdown and civilisation collapse’. Will their protest be a catalyst for change?
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?
The ATOM Project’s mission is to stop nuclear weapons testing. See the effects of the nuclear bomb and sign the petition to ban nuclear weapons testing.
With your help, we can achieve nuclear disarmament, just as we have achieved many other victories in the past. For over 60 years CND has worked to rid the UK, and the world, of nuclear weapons. Without CND and its supporters, the debate on nuclear disarmament might never have taken place, and trea... Read more

“INSANE” idea according to Cosmos lab – lol, the fools.
NASA are looking into this idea already. Read this…

Apparently, you need to have nice manners to get proper recognition now. Science needs to change. Read this article…
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

Shame babies can’t refuse to be born somehow.
Sort of laughed when I saw this idea, google’d it and realised its a thing.
Like the idea, but it would be hard to animate what an atom REALLY looks like.
