  1. Tegmark contradicts himself though – he opens eyes but doesn’t provide a definitive picture – and he doesn’t seem to see a problem with it. Just sayin’

    They still haven’t caught on enough. Old ways with lists alone don’t work as well than having a variety of ways to represent a subject or sub-subject. I highly recommend what this school is doing now, and many others.

  3. But…

  4. 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!””

  5. 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.”

  6. 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.”

  7. Science is way to speculative nowadays, it needs to go back to the basic assumptions, rather than keep adding new ones.

  8. Truth, is a loaded word, but yeah…

    “In mathematics, there are imaginary numbers which cannot be represented directly in reality (the physical world). For example, you can’t have i apples where

    i = √-1 (square root of -1)

    Can we then say that in some sense mathematics is not truth, assuming truth in this sense is that which is manifest or possible in reality?”

  9. omg, don’t laugh… ” I always see the number 1234. I see it as on clocks, in emails, on TV, and just out and about. At first, I thought it was a coincidence, but then I started to realize that it was a pattern….

    Because everything in this reality is at its core is energy, Spirit will send messages through numbers because your vibrational field is so responsive to them. It is what the world around you is made out of. “

  10. Pie backwards anybody? Remember this as a teacher showed me it at school.

  11. Blimey, someone must have been trying hard to find some pattern in there. Just Google’d it and to be honest, would have expected lots more “patterns” than that in an infinite number.
