Science & Technology Q&A for Kids (and others) [October 20, 2023]

The Stephen Wolfram Podcast

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: Is it possible that individual particles have a halo of dark matter, like galaxies have?​ - ​How is antimatter made in the lab, and what makes it so difficult to produce?​ - ​I am curious about your perspective on the recent unveiling of smart glasses equipped with AI assistants (LLMs) by Meta. Do you see this development as a natural evolution of smartphones?​ - But was the separation of matter and antimatter proposed by Feynman, or earlier? And how can this be measured by experiment?​ - Are there anti-neutrons? Anti-elements?​ - Does technology behave differently depending on outside factors (such as atmospheric pressure, temperature of weather, gravity, etc.)? Is there an ideal environment? - Deionized (distilled) water won't conduct.​ - How about solar flares? How do they affect technology?​ - A gamma ray burst hit us last year about this time. It was called the BOAT (biggest of all time). Did we learn anything new from the data from that burst?​ - What determines the color of a leaf when the weather changes? Why are some yellow, some orange and some red?​ - Could there be nanites waiting for more favorable conditions to multiply (nanometer-size robots or organisms) in the samples we brought back from the asteroid Bennu? How could we be sure there aren't any?
