I know evolution is governed by chance and it is random but does it make sense to "ruin" sleep if there's light? I mean normally, outside, you never have pure darkness, there are the moon and stars even at night. In certain zones of the Earth we also have long periods of no sunshine and long periods of only sunshine....
They say it's a picture of atoms, but what are the atoms: the glowing yellow balls or the entire meatball including the darker red? If it's the meatballs, then why do some have apparently two nuclei?...
I'm referring to the human race evolving in the African continent and then migrating to the rest of the world....
Is it a stable/static effect no matter what, or is it a bit more stretchy/bouncy depending on how the object is behaving?...
There are many other bee species that can sting Humans and survive, but the European honeybee has a barbed stinger, so it cannot remove the stinger once it's stung. In attempting to remove the stinger the bee will rupture its lower abdomen and then die....
We often talk about the climate impact based on greenhouse gases, but extracting fuel from the ground and using it in exothermal processes of course also releases energy as heat....
Hi,...
Famously, Oppenheimer and co worked out how close a nuclear bomb test would be to causing a chain reaction of nitrogen fusion in the atmosphere. They made a lot of worst-case-scenario assumptions and still came to the conclusion that no, a nuclear bomb test wouldn’t scour the surface of the world....
Say a dissolvable spring is compressed with a bolt and nut that do not melt in a sulfuric acid solution. The spring has quite a bit of potential energy at this point since it is compressed. Assuming the spring dissolves perfectly (no breakage, just complete disintegration), what happens to the potential energy of the spring?
Now that late spring/early summer is upon us, there's increasingly more headlines about less rain in various places (recent floods notwithstanding). I'm assuming that's because water is evaporating and not returning to those places, but where is it going?...
What are the consequences of not severing it? I imagine you'd have the weirdest bellybutton on earth if nothing else....
I assume it would break into smaller particles similar to the formation of microplastics. I hear about the effects of microplastics all the time. Are the effects of disposed rubber on the environment studied as extensively?
Say I am sitting in the shadow, but the sunlight gets reflected by some window pane onto me. Does this contain enough UV light to give me a sunburn?
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 am simply on a quest to find an effective non-distillation method for purifying isopropyl alcohol used for rinsing resin 3D prints....
Okay, so I know this might be a bit hyperspecific, but I don't know where else to ask it. I'm working through a microbiology lecture, and the professor says the the B strain of E. coli has a tRNA suppressor that allows it to transcribe phage genes that have any nonsense mutation. That seemed a bit vague, so I decided to look it...
