The Stephen Wolfram Podcast

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series. Questions include: What is dark matter? - Why is the Sun's corona hotter than its core? - Are white holes only theoretical or are they real? Is a black hole a sphere with condensed light and matter? or does all that light and matter go somewhere? - A question from 8 years old boy from Houston enjoying this stream but can't stop himself from asking: is it possible now to clone a dinosaur (given that proper quality DNA material will be found)? - How can we tell the difference between science and pseudoscience? - In convection, what drives the flow of air/fluid in the first place? is it just the potential energy stored in the temperature gradient? - Is there any possibility of creation of dark matter in fusion reactors like tokomak? - Why is the moon the same size as the sun?

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series. Questions include: When will we run out of scientific innovations? Is there a limit to technology? - Is it possible to build a place without gravity? - Do you think there is anything between the known particles (and Planck length 10^-33) and your hypergraphs (at length 10^-93), such as another set of "elementary" particles? - Will technology allow for one true universal language [for the deaf, blind, romance languages, Arabic languages, Asian languages, computer languages, etc...], eliminating the need for translations? - Who is the leader in information technology at the moment (my guess is China!)? - Is there a relationship between computational irreducibility and the uncertainty principle from Quantum Mechanics? - Is there a formal definition of Number? - Why all electrons are same? - What temperature does a laser have? - How does a laser work? - How can galaxies retain their shape for billions of years? - Will it be possible to tell a joke in a symbolic discourse language. Who (and what) may find it funny? - You once said that when you were starting out, Feynman gave you a collection of his mathematical tricks for integration, which you didn't end up using. Have you published this? I would really really like to see his notes! See the full Q&A video playlist: https://wolfr.am/youtube-sw-qa

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series. Questions include: How did Alan Turning crack the Enigma Code? - Can you explain Newton seconds law of motion? - How much of science is kept secret, either classified by the military or waiting for monetization inside private research labs? - How should we understand the double-slit experiment with light? If light is made of particles whose quantum wave functions interfere, producing the diffraction pattern we see? Or is light an electromagnetic wave that produces an interference pattern like any other wave phenomenon? - Why does no time pass at the speed of light? - Computers were inspired in particular by Turing works, right? - Where does the word compute in English come from? - Why is the Von Neumann CPU architecture still dominating instead of more parallel solutions?

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series. Questions include: What actually happens with my computer when it crashes? - How come that the humidity inside the cloud is 100% and right next to it is practically zero? What is the answer to that? - What is your opinion Leonhard Euler or Albert Einstein? - How important is money in science? - Is there a maximum limit on temperature based on the fact that particles cannot reach or exceed the speed of light? - How to choose what to work on? - Any advice for someone who has just graduate college with a STEM degree and is interested in graduate school? I'm interested in molecular biology/biochemistry if relevant. - What/who is Nicolas Bourbaki, and how was it created? - Do you think only rich people can "do" science?
