Science & Technology Q&A for Kids (and others) [August 5, 2022]

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 do glaciers form? - Is the orbit of the Earth constant around the Sun? Or is there a variation on a large time frame? - Could it explain the ice ages? - ​​Have you ever studied aerial photos of ocean waves to assess their evolution for irreducibility/pockets of reducibility? - Do you think ocean waves are computationally universal? ​What are neutrinos for? Why do they exist if they don't interact with anything? Could aliens have a purpose for them? - ​​Didn't some neutrinos cause hardware failure in airplanes? - ​If technology could produce a small practical neutrino emitter and detector, would it be useful to send messages with them? - Will holograms as seen in the Iron Man movie ever be available for widespread use? - Why do some foods, like peanuts and crustaceans, cause deadly allergic reactions in some people, while others can eat them daily without harm? How many species have allergies?  - Do we know the mechanism behind this "training"?
