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: What is the history of data visualization? Was the discipline only able to flourish relatively recently with the introduction of computers, or is there a deep and rich history of people creating pictures by hand to extract visual insights from abstract data? - Nikola Tesla was building a machine for the wireless transmission of electricity. It seems like we're getting to a place where we can beam solar energy down to Earth from solar-harvesting satellites. I'm curious what Stephen's take on this is and the timeline for this research/what is needed to make it a reality. - ​​​​From your perspective, what is the importance of compression functions in computer science? - Do we know who designed written language? Or are there still missing pieces in history such that we can't properly map out the history of written work? - What is the stage of development/history around implementing cellular automata in hardware, such as quantum dot cellular automata? What large-scale, hardware-accelerated simulations would be interesting? - I'm curious about the history of eyeglasses. Why has the tech not seem to have advanced much?
