​​How closely are computer clocks synchronized in different parts of the world? How do they synchronize? ​How does the body know when to create scar tissue? Does the body make different scar tissue based on the tissue it's repairing? ​​​What is the meaning of light years? ​​Could you say something about this year's Nobel Prize on complex systems? Is there any relation to your Wolfram model? ​​​​How do messenger pigeons find their destinations? How can I fix dizziness on a boat (new Navy sailor here)? ​​​​​Were you bitten by a pigeon as a child? #spiderman #pigeonman I wonder if there is a difference in accuracy in the sensing of the magnetic field depending on whether it is just one bird, or a few or many flying together.

Why do flies fly around seemingly constantly with no apparent goal whatsoever? Why don't we make houses out of some kind of amber and then carve them? How do traffic light systems work? Does Stephen prepare any of the answers? They are all so clear and thought out. Hello. How are the magnetic north and geographical north related? How come oil is deposited in Arctic regions? Could you please explain what eigenvalues/vectors are and what you can do with them? Thanks. View Less »

What technological and/or scientific capabilities must humans achieve to be able to manipulate and reprogram matter at will? How does the gene-editing technique CRISPR work? Why are routines for sleeping, eating, exercise, etc., so helpful for mammals? When is routine harmful? ​Is there an example where self-assembly is industrially used? ​How harmful are plane flights in terms of radiation exposure? If I were able to create a black hole the size of a marble in my living room, would it destroy the cosmos or just make a hole in my couch? Is it true our electrical distribution networks and neuronal networks in the brain have the same configuration? Why do some speculate there's life on Europa, a moon of Jupiter? How do batteries wear out? In this case, would 3D printing be easier in space? Isn't it weird that our body mostly works fine in zero gravity? View Less »

Since photons do not experience the passing of time, does that mean that all their physical properties, such as wavelength, are fixed throughout their lifespan? Do you think that it's worth investing in and attempting cryonic suspension as a way to continue living? ​​Why does time seem to speed up as we age? How can one learn physics or math at a young age (organizing your life, order of topics, your experience as a young physics enthusiast, etc.)? If the center of the Earth is really hot lava like the Sun, how come it isn't melting everything between us and it? View Less »

​Is there really such a thing as infinity, or is it just a concept? ​Does infinity have a magnitude? But is infinity really a mathematical object? It has no finite quantity. ​How can something without a finite quantity be used in a calculation/computation? What's the difference between counting numbers and counting processes? ​Is rulial space likely to be finite or infinite? ​​How is it possible that the infinity of integers is smaller than the infinity of floats? ​Why can't mules and zonkeys reproduce? What are the limits for different species of mammals breeding with one another? Is it five crossovers on average for everyone? Conceptually, are memes on the internet a species? So how is a species determined just by visual features? Or maybe it's defined by breeding? Last question: Can genetic traits lay dormant for centuries or millennia? Can there be recurring changes after X generations? View Less »

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 »
