Stephen Wolfram Q&A, For Kids (and others) [May 7, 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: Why do server farms consume so much power? And what advances are possible with parallel computing to reduce the power consumption or get more computations per the same power? - Have you ever had a situation where UUIDs collided and caused some sort of issue? - Why does bitcoin use so much power? - What is the correlation between sleep and weight loss? - side note , Wolfram|Alpha lists the "universe atom count" as 6x10^79 atoms, but a 256-bit UUID would have just 1.16x10^77 options, so we may have a problem labeling the universe's atoms. How was the "universe atom count" calculated? - How to convert black and white video to color - How much sleep do you get a night? - What kind of car do you drive? What's the difference between the technology that fascinates you vs. technology that you just see as utilitarian? - Can you explain the differences between DC and AC please? - If I walk into a very powerful solenoid, will the magnetic fields affect my nervous system, or have any other physical effect on me?
