History of Science & Technology Q&A:
Do you know the history of the invention of optical character recognition (OCR)? With recent developments, can you talk about the history of theories of extraterrestrial life and the search for it? Who do you think is the most undervalued scientist in the last one hundred years? Someone who has contributed a great deal to society but has largely gone unnoticed by the public eye? ​​Why were elite physicists (and others) reluctant to embrace computers? I saw an interview with Ed Fredkin where he explained how he tried to teach Richard Feynman to use a Commodore PET, I think it was. "There is a computer disease that anybody who works with computers knows about. It's a very serious disease and it interferes completely with the work. The trouble with computers is that you 'play' with them!" – Feynman Didn't he [Feynman] end up causing a hubbub at Los Alamos because he was personally repairing calculators/computers, rather than the IBM person? ​In the early to mid-1960s, the Soviet Union was very seriously considering what would have been a sort of proto-internet. Do you know anything about this? How do you think kids today would react if they were suddenly teleported 40 years into the past? Have aliens always been referred to as "aliens", or did they have another name in history? Have there been any observable changes to planets during human life on Earth? There's a weird Catholic history of discussing ETs that are neither human nor angel: a theoretical theological field called "exotheology." ​​What is the oldest book that you actually use and is not a museum piece?

History of Science & Technology Q&A:
Are the stars and constellations we see today the same that were seen by the ancient civilizations who first studied them? Do star positions ever change? What do you make of the relationship between rhetoric and math? They are held in contradistinction, but I am thinking of the relation between rhetorical invention and Chaitin's idea of math-creativity. What about sudden novas and comets? Sudden shifts in orbits? Is the Moon moving away measurable compared to human history? As in, since humans started recording history, did the Moon appear to get 10% smaller or so? How will history be able to correct the continuous conundrum of the accuracy of our forefathers' discoveries, inventions and ideas? Additionally, how can we as humans preserve this? How did early civilizations explain supernovas? Did they understand it as a star exploding? How did they come to this conclusion? "The stars are like the Sun, but far away." When said for the first time, this must have been crazy to hear for others. How often were ideas like these disregarded at first? How did researchers of this time convince society of their findings? Is it possible that errors in translation have affected results of research? Are there any examples of this in history? When was the first time anyone considered what the angle of our solar system's ecliptic is relative to the Milky Way's galactic plane? Apparently, the angle is about 60 degrees. Why did science evolve so rapidly in the Western world? What's there to say about alchemy in history? Is that because ethical questions are fundamentally computationally irreducible questions? How do you filter out the "good new" from the "bad new"? It's remarkable that old ideas stood the test of time. View Less »
