I recall an explanation of the formation of Jovian moons on the Harvard Smithsonian “CfA Colloquium” YT channel that casually mentioned how various elements freeze out of the solar wind forming ices, and this is the mechanism that allows formation of moons with large amounts of water and elements that are not found in larger...
I’m curious about building cat toys that are impractically over complicated with Arduino/Maker stuff. Thus the casual curiosity about persistence of vision. I wonder if other animals have something like a different internal clock frequency where the image only forms at higher (or lower) frequencies than most humans.
In physics, it’s common to develop a formula and then stick a constant to explain the unknown. For example, Newton’s theory of gravity uses the gravitational constant G on the formula F = G * m_1 * m_2 / r^2, later on Einstein gave a more accurate explanation with the theory of relativity which does not rely on a constant E...
I was reading about the production of calcium carbide, and that it involves mixing lime and coal in an arc furnace. Is there something unique about arc furnace heating that, say, an induction furnace could not provide?
I came across David Sinclair and his research into reverse aging. Especially, I came across this video by Veritasium with Sinclair. Apparently his team has managed to reverse aging in mice in a lab? Has this been peer reviewed?...
Assuming we are talking about an era when Sol has a thriving space industry and the Solar system is broadly colonized. Current materials science supports structures up to 8 kilometers in diameter, and if large scale graphene production is possible, up to 100km in diameter, at least according to Isaac Arthor....
This is something I always wondered because some people have a bunch of theories about whether your head should face north or south or whatever, because of the earth magnetic field. Is there any science in this or just “superstition”?...
People talk of potential human flight on planets. Somewhere in the recesses of my mind I still wear my inner 5 year old’s caped Superman pajamas, stressing over how many stairs one must jump from to take flight. So is it possible to flappy bird a flying monkey?
I feel like we are ways out from seeing anything like it. From what I’ve seen non-Newtonian fluids typically take a decent amount of energy to stop something and sound wouldn’t have much energy compared to something like a bullet....
After reading the abstract of the paper mentioned here I started wondering, why did human groups migrate away from southerner (warmer) places towards the north which is far colder and has less possibilities to grow crops and wild animals to hunt?...
I don’t care about the math and statistics. I went looking for visual comparisons, where image exposure is adjusted to show how a sunny day on both planets really compares, but I didn’t find anything....
I’m trying to wrap my head around something that appears far more complex than I first thought. I don’t understand the explosive elements and chemistry that drives ash production and the heat to create the eruption column. I’m aware of how molten metal behaves in a foundry crucible with flux and degassing required. So I...
Does anyone have a list of long-term effects that may arise from periods of severe dehydration in childhood, particularly how this might affect overall health in adulthood?
What are the limits to it ? Exceptions etc. Context i saw vsauces " power of suggestions " video. Is the video scripted or was the kids conditions just not real like i can understand the girls condition may be cured through placebo but come on adhd and migraines immediatly cured ?
I know that sound doesn’t travel in a vacuum, you can hear it muddled in water, and different temperatures of air transmit better. But which is the “best”. Let’s say you had a speaker and a microphone in an enclosed case filled with whatever you wanted, which would be the best medium to ensure the best sound...
I under stand that the lower the air pressure, the lower the boiling point of water. Also, some primitive desalination kits are basically evaporators....
I discovered the “Tromatz” bioelectric wave toothbrush, and it sounds too good to be true, which usually means… it is. However, they do link to some journal articles, so it seems it’s somewhat based on fact. There’s very, very little else out there aside from their own website that I can find. Thoughts from anyone...
So, I’ve been reading about the MIT bio suit. It’s basically a pressurized helmet and gloves, and a fancy fabric suit with bands that squeeze you with enough pressure so decompression doesn’t kill you....
