Why do we get random thoughts of violence that we discard?

I'm sure this doesn't just happen to me as people that I talk to say it happens to them. For example I'll be driving home and then the thought to take out the back wheel of an eighteen wheeler enters my head and then leaves, or just sitting in an office and getting the thought of have a grenade go off in the room or some other violent act, but it always goes away and I never act on it and it never returns.

Is it possible to build a circuit or electronic device in such a way that it wouldn't matter which way you insert the batteries?

Posted: 20 Dec 2018 04:36 AM PST

I tried googling this answer, but all I got was tutorials for beginner circuitry projects.

How did Eratosthenes accurately get the radius of the Earth?

Posted: 20 Dec 2018 05:26 AM PST

Eratosthenes's experiment was done on the assumption that the rays of light from the sun are parallel, but at the same time, light in our environment is bending due to refraction? How exactly do you get accurate results with that assumption.

What are the low level computational operations necessary to perform 1 + 1, or other whole number additions?

Posted: 19 Dec 2018 05:42 PM PST

Assuming you have as much memory space as you need, what does the series of steps boil down to logically to perform this operation on a theoretical computer?

I'm guessing there are many ways to do this, but is there a method with the provably least amount of steps that is also capable of arbitrary whole number addition?

Is aluminum arcing in a microwave the same principle as the photoelectric effect or is the interaction different?

Why weren't older CPUs (like the 6502) clocked at much higher speeds?

Posted: 20 Dec 2018 06:59 AM PST

I can't figure out why older CPU's couldn't have been clocked at much higher speeds. I understand that propogation delay is an issue but I would have thought they could have at least run a lot faster without that being an issue. Were old transistors much slower to switch or were the clock speeds just low so they could communicate with slow RAM?

Why are creases in paper impossible to smooth out?

Posted: 19 Dec 2018 11:54 AM PST

What about the material of paper makes that so difficult compared to, say, a folded cloth?

What is the simplest form of cellular specialization? What does it look like?

Posted: 20 Dec 2018 07:23 AM PST

I'm curious about the beginnings of multicellular life; in particular what could cause two single-celled organisms of the same species to specialize in a mutually beneficial way when they're essentially clones?

Were Henrietta Lack's cells special?

Posted: 19 Dec 2018 12:22 PM PST

I was wondering if Henrietta's cells were special to begin with, or if the same result, that is making the immortal cells so important in research, could have been achieved by using canceorus cells from any other person?

Why don't nuclear reactors behave like nuclear weapons?

Posted: 20 Dec 2018 06:32 AM PST

I thought they both used the same process, so why does one explode and the other doesn't?

Why do heavier atoms have more neutrons in their nucleus?

Posted: 19 Dec 2018 07:35 PM PST

So, afaik atoms have a repulsive energy, and an "atomic energy" that keep nuclei together. The latter is more powerful than repulsive energy once the nuclei get close enough. Something I don't understand is how/why MORE neutrons help in heavier atoms such as Uranium. In my understanding, the more neutrons there are, the further away the protons are from eachother thus making the atomic energy lesser? Therefore it's more unstable? I can't find anything online to explain this to me, so I am hoping someone here will share some wisdom with this suffering student.

What determines the distance at which the four fundamental forces can operate?

Do microquakes via oil fracking lessen the chance of large scale earthquakes?

Posted: 19 Dec 2018 02:03 PM PST

Oil fracking causes hundreds, if not thousands, of microquakes. I was just wondering if that constant activity would take away enough tension to make it so a huge one couldn't happen. Or would the activity make the chance greater.
