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 »

Is programming essential for the next breakthroughs in neuroscience, both theoretical and practical? If yes, how, and is Wolfram Language enough to fulfill that purpose? Any opinions on "smart drugs" like custom-made neuropeptides that increase NGF (Dihexa, etc.)? Is the Crick–Mitchison theory of REM sleep essential for understanding how mammalian brains work? Can you comment on the history of plant breeding and computation? Or agriculture as a technology? It seems that old plant breeders think new molecular breeding techniques are a waste of time and money. Modern breeders are using genomic selection with SNPs and gBLUP models. The history of most of our crops is very complicated, usually involving strange hybrids. Will the future bring surveillance and all-knowing government or deep fakes and other things that could be used to fake identity, both physical and digital, in order to get rid of government presence?

Is doing science something intrinsic to the human species, so that if humanity were to be restarted, would science emerge afresh? Can Wolfram talk about pseudo-linear congruential random number generators? Stephen, do you think that we as parents should control how much time our kids spend on computers and smartphones? ​Is it possible to have "many internets"—internet outside of this current internet? Will nations be able enforce firewalls if someone is connecting to Starlink? What's your vision for the future and how do your current students fit into that vision? View Less »
