History of Science & Technology Q&A (February 19, 2025)

The Stephen Wolfram Podcast

Stephen Wolfram answers questions from his viewers about the history of science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa

Questions include: - Can you talk about the history of pi? - "Pi day of the century." - Is pi still being researched today? Or is it a solidified concept? - Was there always a connection between "pi" and "pie"? - Can pi be used for data compression? - Is the only reason pi shows up more than tau because we USE pi more often? - If we used tau, it would have been 24/tau^2 instead of 6/pi^2, right? ​- How was your experience with slide rules? Did Leibniz or Newton use tools like a slide rule? - My 8th-grade (1983-ish) teacher didn't allow calculators, but he let me use my slide rule. ​​- Would you rather be stuck with just a slide rule or just an abacus? - What is your favorite "artifact from the past" that you own... any interesting stories? - What's your favorite artifact from the future? - Many key ideas in computer science existed before we had the hardware to implement them (Turing's computer, neural networks in the 1940s). What ideas today do you think are ahead of their time in the same way? - Technology has progressed at an incredible rate during the last two centuries. That seems quite unusual relative to other periods in history. Are we bound to enter a new era of stagnation or regression? Or can we just keep going? - How would you think about cellular automata if you were born in, say, ancient Greece/Rome or Egypt? Or even the 1800s? - ​​Is there a history of people discovering the concept of the ruliad and thinking about it from a different perspective (mathematical, scientific, religious or otherwise)? - I would be interested in hearing about the bug of Alan Turing. - It seems like our definitions of "science" and "technology" have evolved over the years. Are they historically the same thing?
