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: My question is, When we transfer an electric charge to a conducting sphere, does this charge cause some metal atoms to become ions? If they do not become ions, where do the electrons go? If they become ions, then their chemical properties must also change. Which answer is correct? - In the recent LA fires, I've seen buildings burned but plants and trees next to them just fine. Is there some physical or chemical reason why the plants are fine and buildings not? - Do photons collide? The light coming to us and the light going back to the source? - I have a question about antimatter. What do we use to contain antimatter? - How would you think about photons as a 10-year-old? What's an easy explanation? - What is antimatter anyway? Is it supposed to be something that pairs up with matter to maintain some kind of conservation law? - Are we unintentionally leaving behind a time capsule with light waves? Will scientists of the future be able to look back in time through light?
