Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa

Questions include: How much does a cat's tail affect its ability to land on its feet? Do cats without tails tend to fall over frequently? - ​​​​​Could a planet have "internal" rotation of its molten core while having a stagnant outer surface, or perhaps a slowly rotating surface? - ​​​​What's the deal with the Dzhanibekov effect (the observation a cosmonaut had when a spinning bolt flipped in space)? ​​​- The head and the shaft are rotating in unison. The head has more inertia around the axis. Don't forget the bolt is in a standing pressurized chamber of air. - ​​​​Will the Earth eventually cool down enough to stop producing a geomagnetic field? - ​​​​​Tails seem to be vestigial for many organisms.
