    This guy looks like all the TA's I had in college- but his riveting intellect and presentation skills were rare in my own experience. This one will make you think- and think about, How and Why- we act as we do.
    What's "scary" about this guy is.....the work required for a singular class. I was originally thinking "this is ONLY 3 credits?" ....but 5-6 makes sense given the commitment.

    Think about the amazing time we live in when you can learn Human Behavioral Biology from Professor Sapolsky, or learn physics from none other than Richard Feynman with his lectures posted on TVclip, or learn cosmology from Dr Leonard Susskind. And all you have to do is have the initiative to watch them.

    Okay. As a Finn I just *have to* comment on this bear/pear thing 😂 We don't really have finnish words with 'b' except words that are of foreign origin. That's why we don't really have very distinguished difference in pronouncing 'p' or 'b'. When we say b it's more in between p and b, and a lot "harder" sounding than in english. But because there's not really a chance of misunderstanding with similar words, we don't need to put emphasis on making the two sounds different. Same goes for 'd' and 't' which I feel like are also often mixed in finnish. ('D' being also foreign letter to our language.)

    you have none warrior thinking, the boundaries you have are not the thinking of a warrior. will power throws lots of your logic out. worries or terms of victory is not a category or language is out side of what you are thinking, as a matter of fact if I beat you enough I can make you say a line or odd shaped things are called a square or a hippo if I wanted to. I am not impressed.

    There's actually a valid, mathematical form of reasoning for the number chain, that still ends in 42.
    And it's also the answer to life, the universe and everything, so go figure.

    37:38 I can believe that their blood pressure would be high, but I can't buy the idea that they're "going through thousands of calories a day." Think about it for a second, imagine how much heat would be produced! You burn even just 10 calories in a sprint and your body starts making you sweat to get rid of the heat!

    The main link here in all this Biological Discussion is that we're all Carbon-based, i.e. 'Organic'.

    The fact our genome is 'similiar" to the Chimpanzee is obviously nothing that amazing when remember "The Big Picture" and that we all (every single Stone, Plant, and Creature, etcetera) originate from the same planet.

    I guessed 42nd & never been to New York City. The number sequence of 4th, 14th, 23rd, 34th I looked at as a pattern. 10 digits separating 1st 2 numbers, 9 separating the 2nd & 3rd, 11 separating 3rd & 4th making it 8 digits between 4th & 5th. With this pattern the 6th number in sequence would be 12 higher than the 5th number, making it 54th. Followed by 61st, 74th, 80th, 94th, 99th, 114th, 118th, 134th etc

And he's so proud of himself, LOL! So someone could torture HIM or his loved ones and it wouldn't be their fault. Wonder how quick he'd be to excuse away something like that, LOL!

    And YEP people like to be nonchalant and round-about and if they don't get to the point it doesn't bother them ya great instructor. Wheres your Science! But his charisma is warm and loving i bet he is a great man he is just teaching opinion in my opinion...ha and introducing weird metaphors that pertain to minimally subject oriented material.He is a pleasure to hear speak tho. Audiences like to be involved or the are totally unresponsive depending on the instructor/ when my instructors have trouble getting a class discussing started my ole genius clown WILL bark out the answers and get my class mates involved im great at it because i personally confront a subject on a really wrong basis prompting those tp speak out the error and bark out the truth by nature....have fun with this ...
