Science & Technology Q&A for Kids (and others) [December 29, 2023]

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: ​Do we know enough neurobiology to assert that the human brain works differently from a machine learning or artificial intelligence model? - How would you begin an introduction to chemistry course? - How are chemical reactions balanced, and why is it important to balance chemical equations? - Is it right to still use the periodic table today, or is it an order of the past? - Is there research on computing outside of the classical (binary) and "quantum" states of electrons, for example biology-, chemical- or light-based data storage and processing? - Molecules are graphs. - The system of balancing molecules and equations is just a new variation of "this" equals "that." - What strategies and techniques can be employed to effectively control and optimize chemical reactions for various practical applications, including maximizing yield, minimizing waste and achieving desired products? - Molecular-level mechanisms govern the magnetic properties of materials. How do these mechanisms lead to phenomena like ferromagnetism, paramagnetism and diamagnetism? What about radioactive substance reactions?
