  • Tadashi discusses pressure and lift... with a toy of course!

Some people suggest they may be a better fit on Brady's dedicated physics channel (called Sixty Symbols). In response, the reasons they are on Numberphile are: 1) Tadashi, while certainly a modern polymath, is based in a mathematics department. 2) This sub series (with its animation and extra production work) has been supported by the Mathematical Sciences Research Institute, a Numberphile collaborator. 3) Some of the previous and future Tadashi videos are more math-oriented than physics - and it just makes sense to put them on one channel rather than dividing the series between two channels on an ad hoc basis. In a multi-disciplinary world, it is challenging to run YouTube channels which people come to associate with just one discipline. That said, feel free to go over and watch hundreds of physics videos on Sixty Symbols --- https://www.youtube.com/sixtysymbols

    I'm a simple guy: I see a Tadashi video, I stop what I'm doing, and watch it.

    Infinitely many mathematicians walk into a bar. The first orders one beer, the second one two, the third three and so on. After some time, the bar man is fed up, and says: Just give me the 1/12 beer already!

    This was a very interesting way of looking at fluid flow without being overly reliant on Bernoulli's principle which has always irked me as it's always seemed to be used as a crutch. I remember playing with household items, like the spoon with the tap water, and always wondering why things like that happened. Also, can I just say Brady and Tadashi are looking great today! More love to knowledge enthusiasts of all kinds.

    The spoon slow-motion was worth the time, by the way

    The spoon effect was such a marvelous example to follow the professor's explanations. At first, I was somewhat skeptic about the action-reaction argument, but this example really did give me a more intuitive understanding of the underlying principles that were being discussed. Also, comparing pressure to potential energy was a nice touch. All in all, I like the clarity with which the professor speaks and explains things in this video.

    I just love how respectfully he talks to him, by saying "professor,...."

    That's a super classic trick but I never realize that the ball is spinning!

    Yess finally someone who says the truth! You can't use Bernoulli theorem in this case! Awesome video 3 :)

    The notion that a gas can pull anything is misleading. Vacuums don't pull anything. It is gas on the other side that starts pushing that causes stuff to move into a vacuum. That's how entropy works.

    Ahh, he's describing the "Coandă effect"
