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 am seeking a scientific explanation behind this phenomenon which is unprecedented to me....
I let people rate how much they like different things on a scale of 1-10. How do I actually tell if people like one thing more than another thing if the sample sizes are different? This is not about any real scientific study, more like a personal test :)...
Where does the sound go to when you’re in a spaceship in space?...
In the famous double slit experiment, setting up a measurement device that watches which slit an electron passes through changes the eventual outcome on the screen, causing the wave function to collapse....
Amouranth, the Kick streamer, is allegedly brewing beer with her vaginal yeast. It’s an obvious publicity stunt to squeeze more money from her impressionable and “thirsty” audience....
Feels like a shower thought, but I seriously want to know if there are any implications, because it seems like identical twins are able to sense, understand, and almost be extensions of each other - finish each other’s sentences/thoughts. Some even claim to be able to sense their twin when they’re separate. Hard to believe,...
I'm thinking of switching fields within STEM and there are some mathsy modules which I missed out on during my undergrad (biology) that would come in really handy right now....
Let's say you are dying of starvation. You pull one of your teeth out, causing blood to slowly seep into your mouth, which you swallow. The calories from the blood getting digested will delay the time you die of starvation, right? Or will losing blood while starving kill you faster?
I grew up in an evangelical household and went to a Christian school where they only taught creationism (and a little “micro evolution” but not much)....
Asking because while I see that paint hardeners exist in the USA, there doesn't seem to be anything similar in my country (Brazil)...
I’m just curious.Strange matter, according to my research, is a perfect state of matter with perfect density, etc. If it is like this, does that also mean that it violates the law of entropy?Because let’s see, if it converts matter around it into stranger matter, and after that it doesn’t react with anything else, I mean...
Is the CMB only red shifting in frequency or is there more to it, and over what time scales and distances would one notice a significant difference?
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 was dealing with a problem which stated that two objects were moving with same velocity v and one was a car with mass m and another a truck with mass M, such that M > m. They collided and came to a halt. Their collision lasted for 1 second. Which experienced a greater force of impact?...
Why is it that I am not able to read a book without moving my eyes if the entirety of the page is within my field of view? Why do I have to center my eyes on an object to observe it fully? And why is it that I am still able to view changes in surroundings in the edges of my field of vision despite there being supposedly no way...
I seem to remember as a young child being told that it is safe to touch a Van de Graff generator (for the hair demonstration), but that if you let go before it is safe you will get a nasty shock. I know a bit more about electricity now, and I'm a little skeptical now. Is it possible to get a shock from letting go of something?
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...
I mean, I’ve heard that you can typically only survive about three days without water, but what exactly causes your body to fail when you dehydrate too much?...
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 understand how lucky imaging gets the results it gets, but I’m wondering specifically how the 10% of frames are chosen....
I am simply on a quest to find an effective non-distillation method for purifying isopropyl alcohol used for rinsing resin 3D prints....
