    Medical What is the role of the neocortex in human intelligence and movement?

    If you want to understand how the neocortex works (the seat of intelligence, perception, and movement in humans) in relation to its surrounding structures, there is an excellent book called "On Intelligence" by Jeff Hawkins By the way, he is one of the founders of Palm Mobile Computers.

    Could a Billion-Year Technology Gap Exist?

    krauss proves that the universe places a limit on computation Maybe this can provide some insight - Krauss et al. have proven that the universe places a limit of about 600 years of exponential growth of a societies information processing capability http://arxiv.org/abs/astro-ph/0404510

    1) 2) time index: 21:20 "It turns out, most of the mass of the proton comes not from the quarks within the proton, but from the empty space between the quarks. these fields produce about 90% of the mass of the proton, and since protons and neutrons are the dominant stuff in your body, empty...

    Thanks, does that then mean that if we were ever able to verify that the universe has a finite mass, it would imply that the universe must be finite in spatial extent, and therefore not perfectly flat? Conversely if we were able to verify that the universe is flat on the largest scales, would...

    I am sorry to bring this up again, but I have just understood why I drew the conclusions I did from what he says here. The only way that I can see these two statements being logically compatible is if the space between the quarks within a proton is no different from the empty space between...

    'A Universe From Nothing' by Lawrence Krauss, AAI 2009

    Hi Chalnoth, Please can I ask you to elaborate on this, as I am struggling to conceptualize it? To me the property of being closed (angles of a triangle add up to more than 180) implies that the topology will wrap back on itself. Can you give some examples of shapes where this is not the case -...

    I was wrong - I have just given this to an intelligent, but very non mathy person, and she is glued to the screen - laughing hysterically and obviously fascinated by what science can tell you. I have to now concede that what he is doing is very important - taking science to the masses and by...

    Center of the Universe - Is it Possible?

    there are certain parts of the analogy that are not important - I discussed it here: https://www.physicsforums.com/showpost.php?p=2202479&postcount=6

    Thanks for clarifying that :-)

    'A Universe From Nothing' by Lawrence Krauss, AAI 2009

    Yes, it does bother me, are you saying that he measured that the 70% of the mass of the universe is caused by dark energy, but also that the mass of the universe is infinite because it is infinite in spatial extent, and therefore the mass of the dark energy is also infinite? What also bothers...

    what I said is that most of the mass of protons and neutrons can be attributed to virtual particles.. it is that mass that we can calculate using the theory of the strong interaction and powerful computers.. _______________________________ Lawrence M. Krauss Foundation Professor Director...

    Well, I have transcribed some relevant sections of the talk, and it seems to me that my bewilderment by his contradictions is not irrational. time index: 19:35 what could contribute a term like this, and we know the answer - nothing - by "nothing", I don't mean nothing, I mean nothing. If...

    nice reply - thanks - I put this question to Prof Krauss, and he responded to me, pointing out where I was going wrong. I have asked him if I can post his reply here, I will do so if he gives me permission.

    Well, you seem to be implying here that most humans are born with the potential to understand the most advanced math that humanity has produced. As far as I know, that is not accepted to be the case, but I do take your point - most humans pay very little attention to developing their...

    'A Universe From Nothing' by Lawrence Krauss, AAI 2009

    I think that I might be starting to see a pattern emerge - it seems to me that the intellectual abilities that scientists like Krauss are so far beyond what ordinary humans are capable of, he can't even articulate them at all in a way is intelligible by the majority of humans on this planet...
