Science & Technology Q&A for Kids (and others) [August 19, 2022]

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 are there still mysteries in our knowledge of the human body in spite of exponential advancement in our understanding? - What are the approximate odds that two people have had the same fingerprint pattern? (odds of a collision among all fingerprints within the enumeration of the parameter space of fingerprint patterns) - Isn't the finger prints a two dimensional reminiscent from the torus like inversion that occurs in the body? - Is there a way to make trees grow faster? - If there exists a machine code for our bodies. Is the model you're working on some kind of a debugger? Could you explain the things you expect to be able to predict with your theory? - So conscious is like user space code and unconscious is like kernel space code? - How far away are we from finally doing away with physical smartphone screens and replace them with virtual projected screens in front of the user, which can be made as big or as small as one desires? - MIT developed AlterEgo reading your mind so you do not need to type. - Ed Fredkin - Tablet PCs didn't take off in the 90s but much later. Why? - Is typing/writing a bottleneck on productivity? I wonder if thought typing will have a significant effect on how much most people get done. - Thanks for that answer[Ellipsis]I guess for now we will just have to keep getting excited every time someone comes up with yet another smartphone with a slightly bigger (by a few mm) screen! - What if somebody falls asleep in front of his computer with the electrodes still on their heads and starts dreaming, then typing in his/her dreams? - If you drink MILK before u go to sleep you will remember YOUR DREAMS. There's some bio chemical there - Dreams are so interesting... from the habit of having a dream journal (writing them down as soon as you wake) triggers you to 'remember' the dream. But who's to say it's an accurate memory, or just an on demand created thought - How come that we sometimes experience more subjective time in a dream than actually has passed? Does our brain somehow "outruns" the normal computation rate? - What do think about molecules (supplements) that increase synaptic plasticity which controls how effectively two neurons communicate with each other I look for molecules to boost my brain power? - But what is a memory really? Where does one memory start and another end? What is the boundary between the "interior" and "exterior" of the mind? - The human brain does seem to have a bias towards discrete categorization though, e.g. the alternating illusions, Yanny/Laurel effect. - Companies into AI (like Tesla) put a lot of emphasis on 'vision' over other sensory detection. Is that also true for us as human beings? Are some senses 'more important'?
