Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series.

Questions include: Have you discussed the Wolfram Physics Project with any string theorists? - ​What is the possibility of building an unmanned space craft to 'hitch a ride' on a comet, to reach (and perhaps launch) the space craft out of the solar system? - recently watched a video on YouTube by Anton Petrov where he discussed a leak from the radio telescope laboratory about an unusual radio signal from our nearest stellar neighbor, Alpha Centauri, and in the video he said that the reason the signal was so unusual was that it was stuck to a specific frequency of 982.002mhz and I was wondering your thoughts on the unusual nature of it's specificity? - ​Can you explain how APIs work and some difficulties in matching property addresses (variability in how an address is written) to relational databases? - If the average human brain was represented as a PC, what would its technical specifications be? - ​Why is difficult for our brains to perform many simple calculations in a row? - ​Is the eightfoldway of Murray Gell-man easier or more difficult than just learning Quantum chromodynamics?
