Science & Technology Q&A for Kids (and others) [November 19, 2021]

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: What's the physical limitation of growth speed of humans? Can you get from 10 kg to 90 kg in a month theoretically? - What is the function of the human heart? Is it best understood as a pump or in a different way? - Humans exposed to prolonged micro-gravity conditions suffer from well known health issues. Short of 1g gravity, do we know the minimum gravity required to prevent such issues e.g, 0.1g, 0.3g, 0.5g etc? - ​How can quantum computer solve the protein folding problem? - Is being able to get to the lowest energy state a statement that there is a "continuous" series of energy states that the molecule has, that the transformations from one state to another is "smooth" enough? That there is no energy state that is "isolated" from all others?
