What's the equivalent of physics constants for social studies?
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...
Why can't Strings in String Theory be replaced with Springs?
How do you clean?
You dirty dirty… It’s time to show off! What is the most extreme cleaning you’ve ever performed?
Why did groups of human beings migrate to northern zones of the world, and how did they survive?
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?...
Why did the sound vanish from all of my recording devices at the same moment?
I am seeking a scientific explanation behind this phenomenon which is unprecedented to me....
How do I calculate if a test like this is statistically significant?
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 :)...
Sound in space
Where does the sound go to when you’re in a spaceship in space?...
What if the measurement device in the double slit experiment were a light year away?
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....
is this the starting point of a new cosmology ?

[Mycology] Are yeasts analogous to each other, to the point they can be used in food interchangeably?
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....
If GPTs only predict the next word how do they decide between "a" and "an". Wouldn't this have massive effect on their abilities?
Is it really possible to make a house very good in passive heating and passive cooling, and can an apartment building do it as well?
Is it possible that monozygotic twins are quantum entangled at conception?
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,...
Certified online course for learning STEM subjects?
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....
Could death by starvation be delayed by drinking your own blood?
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?
Sources to learn about recent evolutionary discoveries?
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)....
Hi, can someone explain to my small brain what reaction this is or what happened? ( imgur.com )
When I was cleaning a heatsink from an older laptop, the aluminum, and I think also a bit of copper, started to disintegrate very quickly and sometimes violently. I used a cleaning solution that was made for removing thermal paste and cleaning CPUs and PCBs. After some time, the only thing left of the heatsink was some grey...
What can I use to harden acrylic paints or resin?
Asking because while I see that paint hardeners exist in the USA, there doesn't seem to be anything similar in my country (Brazil)...
Does stranger matter violate thermodynamics?
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...
How does the Cosmic Microwave Background radiation temperature variation change over various time scales?
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?
Utility of Arc Furnace Versus Other Heat Sources
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?
Are certain typos/grammar errors harder to read than others?

What's the difference between Force, Impulse and Force of Impact?
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?...
