Science & Technology Q&A for Kids (and others) [June 10, 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: ​​As the Wolfram Language grows, will the number of lines of code ever shrink? What could cause such a trend? - ​​​​Scientists are trying to elucidate the origins of life on Earth. The current focus is exploring the "RNA world." This occurred 4.5 billion years ago. Could there have been dimensional fluctuations back then? - ​​​Why are small children able to spin around so quickly without getting dizzy, while adults become nauseous? ​​​- Do we still need the appendix? Are there any parts in our body that we "evolved away"? - Is science getting harder? Are ideas getting harder to find? - Yes, the more we've learned, the more we've learned that there's a lot more to learn! - ​How ironic then, that Albert Einstein started his revolution in physics while working in a patent office! - One thing that interests me is predicting what the future will look like (Alan Turing predicted computers would be capable of playing chess 50 years from when he said that, and sure enough, by 1997 they were able to do so).
