Stephen Wolfram Q&A, For Kids (and others) [August 7, 2020]

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series. Questions include: What is the difference between fusion and fission? - What is the difference between regular helium, like those in balloons, and Helium-3? - Can you explain the physics of why ice is slippery? - Would you mind explaining Van der Waals force? - Does quantum mechanical tunneling play much of a role in nuclear fusion? - Are you planning on ever releasing the raw data of all the possible simple programs you generated while working on "A New Kind of Science"?  - When Andromeda collides with the Milkyway, what's going to happen to Life on Earth, neighboring planets and solar systems? - What advice would you give to someone who is starting to study analysis from scratch (i.e. from Zermelo Fraenkel axioms and so on)? - Speak about Einstein's correct prediction of the perihelion of Mercury when people realized Einstein's theory was better than Newton's. What might be the equivalent for the Wolfram Physics Project? - What gave you the confidence to study physics since you were a kid?. What advice would you give to a kid interested in learning that has an internet connection and a Raspberry Pi? See the full Q&A video playlist: https://wolfr.am/youtube-sw-qa
