Raccoons are famed for using their opposable thumbs to wash off food. Because early humans were also scavengers with opposable thumbs, could washing food have been a similar advantage that helped them evolve into their niche?	1
What'd the climate be like on a terrestrial planet wiht a 90 degree tilt like Uranus? Would this planet be habitable? How would life survive on this planet?	1
What are some aspects of psychology that are definitely biological, rather than social?	1
How would it affect a chemical if one of the atoms involved decayed into a more or less stable element?	1
This physics video says that, because light functions as a probability wave that takes all paths, you can place two mirrors adjacent to eachother and have the probability constructively interfere so that photons reflect as if there was a mirror between them. Has this ever been tried in practice?	1
Is there an evolutionary reason acceleration is inherently fun? Could it potentially serve to train our body's understanding of physical movement, thus making us more agile?	1
Could you make a florescent mirror, like a mirror which takes in a UV image and reflects a visible light image? Even if it was impossible with current materials, could it be possible in general?	1
Why are the first land animals always depicted as coming out of the sea? Wouldn't it make sense for them to come out of fresh water environments, given that those are much more intermingled with land, and are generally where we find amphibians today?	1
In a video game, like pac-man, you can approximate a world shaped like a cylinder, a mobius strip, a sphere, or a torus just by teleporting the player to different parts on the edges of the map. How would you do this for a Klein bottle?	1
From what I understand, our bodies use blue light in order to tell when it's daytime, which is why electronic devices mess up our sleep schedule. Where would the moon stand in terms of this? Are people more awake during full moons, when relying on natural light?	1
