What do you think of psychological personality tests? Which type are you? ENTJ is the CEO personality type. Is replication a necessary criterion for the validation of a scientific experiment? So are personalities clustered or not? ​I wonder if there are datasets available. Can you explain the science behind the iron rod that bored through Phineas Gage's head and, although didn't kill him, hugely impacted his functionality? AI, politics and decisions, please ​How crazy would it be if politics becomes like hedging, where it's all run by algorithms: Vote algo1 for prosperity! Algo3 is tough on crime! Algo 4 is more compassionate, etc. View Less »

Why are there no trees in the ocean? Did you read any Kant on the beach this week? (If so... any takeaways?) ​​I'd like to hear the differences and relationship between computing and modeling. ​Why is the thorium nuclear fission reactor not more popular? ​Since DNA is a double helix, shouldn't it work as having something similar to error correcting codes? In theory, if you dilute nuclear waste back to the same concentration as the ore and put it back in the same mine it came from, what would be the problem? What is your altcoin portfolio? Can the world become more valuable even though there isn't more stuff brought in from outer space? View Less »

Can you talk about turbulence and why it's the greatest unsolved problem of classical mechanics? Is it true turbulence can't be predicted from the underlying physical equations (Navier–Stokes)? How about intelligent fluids that are about to take over the world? Which self-driving technology is better, imaging or LIDAR? What are finite fields and why are they important? View Less »

​Can you explain neutrino messaging and whether it's feasible to build a neutrino messaging system or neutrino internet? Are the results we see in particle physics valid even outside our gravitational field? The elementary particles we discover in our accelerators—could they be bounded to the physics we see on Earth, or other "things" produced in space? Why should gravity, which is considered to be a very weak force compared to the others, have any significant effect on high energy particle physics experiments? I have a question relating to thermodynamics. How could we detect and remove the impact of refrigeration and air conditioning indoors on outdoor global temperatures? Can we build a giant magnifying glass and put it in orbit to create a death ray? A related question: does a magnifying glass steal energy from its surroundings? Can you name any technologies that were fragile and unreliable 50 to 100 years ago but are extremely reliable and widely used now? Are there any early-stage fragile technologies today that have the potential to be widely used 50 years in the future? ​Is there anything that is the opposite—something that is fragile today that was stable a century ago? Does technology universally always get better? What will be the next advancement in microprocessors? What about 3D lithography? View Less »

Why does an electron fall or lower its orbit to the "normal" state after having being in an excited state? ​​What does an infinite amount of integers and decimals between two integers say about the nature of the world? ​What is a time crystal? ​What is your opinion on the technological and economic feasibility of asteroid mining? ​How does sophisticated philosophy relate to sophisticated math in both the thinking processes underlying them and the intellectual firepower in effect? ​How did your mother and father encourage your own pursuits in science? ​​​If knowing absolutely nothing is represented with 0 and knowing everything is represented with 1, where do you think the human race is at this moment and what are its limits of knowledge? ​What could knowing the machine code of the universe unlock in technology?

Is there a reason why math has an order of operations, or is it just "because we decided on that"? What does a day in the life of a scientist look like? ​ ​What is your opinion about reproducible research? ​Stephen, I loved your conversation with Greg Chaitin! You asked questions that reminded me of the questions that we ask you. Please make some podcast episodes where you have guests to whom you ask questions! ​Will teleportation ever be possible, even if only for, say, a photon stream? If so, could a probe sent into a black hole be able to transmit back images across the event horizon using this technique? View Less »
