​What are some of the NKS implications for medicine? ​What's the minimum amount of DNA pairs that is not "obviously basic" and could perform universal computation? Would this be the lower bound for some heuristic of complexity of life? ​Is there any fundamental computational boundary to a super-intelligent AI doctor capable of connecting all the medical specialties? ​Why are we are not prioritising research in longevity? What makes HeLa cells "immortal" and how common are they in humans? Or was Henrietta the only person ever to have "immortal" cells? Do other species have cells like HeLa cells? Why can't we reproduce cell membranes? Aren't they made up of proteins? How do you organise/prepare for a talk? How many hours should a scientist work per day? Why isn't nuclear power used more and is there a way to make it smaller and safer so that it can be used like portable power generators? What do you feel is the place of philosophy in modern science?

​Does Wolfram believe in supersymmetry? ​Do the particles mass vary or are they exactly the same all the time? ​Gravitational mass always the same in the history of the universe? Is the inertia mass always the same, how does that work? ​What is category theory? ​Is it possible to make a lens/ camera for wifi? What would differ from a regular cmos digital camera. Can there be a 'pinhole' wifi camera? ​What would happen if you live streamed a video from a vessel that is going near the speed of light? Would it be slowed down? ​What's up with the muons discovered? View Less »

​What is beta decay? ​I'm confused about the mass of quarks inside of protons/neutrons, somewhere I saw numbers of only a few electrons and the rest is binding energy? ​Do you think you'll be able to wirelessly "charge" your house in your lifetime? [like Tesla's wireless electricity experiment but practical] ​Didn't Tesla invent wireless electricity? ​Does solar count as wireless charging? ​Can human electro magnetic field interfere with electricity? ​What is something you have recently changed your perspective or opinion about? ​"I've answered why there is something instead of nothing, tune in next week" View Less »

​What are the biggest differences you notice about how physicists think vs. how mathematicians think? ​A typical text file is a few KB, a typical audio file is a few MB, a typical video file is a few GB. What would a typical file size be for smell, taste and touch? Is there a reason why a quantitative change leads to a qualitative change? ​Do you think there is a market for small rockets in Europe? ​Would those LEO satellites block out sunlight? ​If we keep getting more precision with atomic clocks, can we use a set of well placed atomic clocks to use gravity's effects on time to create a 3D map of some region of space (say to spy in a room, or see into the ground) to make out things with a centimeter feature?

​Is there any experiment in computation similar to Miller - Urey experiment? ​Can there be life inside a solid? ​Will it be possible in the future to create an atmosphere on a planetary scale? ​Why can electromagnetic waves transfer in space while sound waves can't? ​Could the physics project predict a phenomenon that can't be observed by humans but would be "faster than light"? ​What about low frequency electromagnetic waves from giant electromagnets ULF could they be sent and detected like from giant coils? ​Do you think AI based government and regulation of economy will be a reality in this century?

​When an electron moves from one energy level to another and it releases a photon, is the direction of the photon random? ​Can you please explain inertial and non-inertial reference frames? What are their implications? ​Why do humans have an appendix even though it is unnecessary? ​Why do we have folds in our ears? ​Why do we have folds in our ears? View Less »
