  • As an example, UW Madison which has a fairly large and profitable athletics program generated 12 million in profit last year. They aren’t the largest athletics program in the country, but it is bigger than many. Sits around the middle.

    The patents and IP owned by the university provided $134 million in grants and support. Again, the school has a large STEM component, but it isn’t a top tier university. Again, sits around the middle. The organization providing this funding manages its investments carefully and intends to provide this level of funding year after year.

    Research departments generated more revenue and the funding is likely more reliable.





  • I think in their crazy world, the north pole is at the center of the earth disk and Antarctica is actually an ice wall around the perimeter that keeps the water on the disk. Therefore, Africa and Australia are on opposite sides of the disk (like left-right not heads-tails) or are near the out perimeter and no one would build a cable going across that long of a distance.

    If that makes your brain hurt because of the stupidity, that’s because it is. Flat earthers are only good as the target of a joke because we can all agree that it’s stupid. There are some entertaining videos on YouTube of people making fun of them, or of themselves proving themselves wrong.



  • The video you linked summarizes the intent and benefit of Veritasium videos at about the 2:25 mark, stating that they are for a general audience. I agree that Veritasium isn’t perfect, and doesn’t provide complete depth, but they do a good job of creating interest in topics. So they accomplish their goal.

    Additionally, the video you linked is wrong about the principles it discusses. The drift and diffusion velocity (group velocity) of electrons and holes is small compared to the speed of light. The relativistic effects discussed are caused by the phase velocity, which will be closer to the speed of light in the medium for even small currents.

    Edit: originally, I incorrectly worded the last sentence which implied that the electrons and holes had a phase velocity equal to the speed of light. I hope the statement is more clear now, but I’m happy to provide additional clarification if necessary.




  • It’s an interesting question, but a bit vague. Even at room temperature, relatively needs to be considered for the motion of electrons.

    You’re probably thinking about bigger stuff though. The short answer is that temperature is unbounded so yes, there is a temp at which it is significant for the motion of all particles. I think inside of stars this can happen, but my knowledge jn that area is pretty limited.

    Veritassium has a recent video about some of this that you may find interesting if you haven’t already seen it.
