What is the difference between astroparticle physics and astrophysics? Which is more interesting in your opinion? Why do doctors say that no vaccination can be 100% effective? ​​According to Wikipedia, some bowhead whales have been "estimated to be between 135 and 170 years old." Is this alleged estimate correct? Can some mammals live to be 200 years old? ​What's different in the vaccines? Like what's the difference between one and another? View Less »

How common is "atomic oxygen" in the universe? If temperature and pressure both come from gas molecules bouncing around with a certain momentum, why are the two different? And what is the difference between the two? ​How do I educate my children like you were growing up in order to give them the potential for any STEM field? ​If you were in your early twenties and just graduated college, which field would you go into? AI/machine learning programming, aerospace engineering, blockchains/crypto? ​​Is there a closest packing for Spikeys? What are the smallest and largest Spikeys ever constructed or discovered? ​Speaking on AI, do you think we will see artificial general intelligence (AGI) this century? If yes, what is your best guess as to when? ​So what's the deal with superfluids? Do they have any useful purposes? View Less »

What's the physical limitation of the growth speed of humans? Can you get from 10 kg to 90 kg in a month, theoretically? What is the function of the human heart? Is it best understood as a pump, or as something else? Humans exposed to prolonged microgravity conditions suffer from well-known health issues. Short of 1g gravity, do we know the minimum gravity required to prevent such issues, e.g. 0.1g, 0.3g, 0.5g, etc.? ​How can quantum computers solve the protein folding problem? Is being able to get to the lowest energy state a statement that there is a "continuous" series of energy states that the molecule has? That the transformation from one state to another is "smooth" enough? That there is no energy state that is "isolated" from all others? View Less »

Do you think will we get anti-gravity cars? How much memory does a rock have? Do protons or photons have memory? Do orbits have memory? When is someone considered dead? How do we define the line between alive and dead? How do sparrows in a flock know how to all change directions simultaneously? Do you think it's more important for humanity to look to colonize another planet or try to look after the Earth and make it habitable for the future? Can we push the jet streams? View Less »

How do induction cooktops work—specifically, without burning your hand if you touch them? How does a shortwave radio signal go completely around the world? Will new logic or mathematics operators be invented or discovered? Why do we have two different things—such as numbers + operators, data + algorithms—and we represent many things with those two things? Why not three? Why not four? Why not one? What's the difference between CPUs, GPUs, TPUs and ASICs? How viable is a big numerical reverse database to identify closed forms of real numbers, such as Plouffe's inverter? View Less »

What is 1/3 of a century? Why do mathematicians create models if machine learning can create more complex and better models? Hello. Can you create gold from lead by putting some lead next to a big pile of plutonium? How proportionate is public opinion of a person to actual achievement of that person generally? ​How would one go about building a UFO? What technology do we need for that? What mathematical achievements/solutions do we need? Thanks. View Less »
