How dense would the atmosphere need to be to result in a cataclysmic chain reaction during a nuclear explosion?

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....

We shouldn't have to work 40 hours a week to afford a basic life. We do because our currency is constantly losing value. This is by design.

There's a lot of talk about inflation and its causes. Is it corporate greed? Supply chain issues? One clear base cause of inflation less talked about is having an inflationary currency supply. Any other inflation caused by supply chain issues, corporate greed, lack of market competition, etc is just added on top of that. Fiat...

tRNA suppressor mutation to transcribe nonsense mutations

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...

Wall framing question: stud spacing between openings

I'm framing up a non-load-bearing wall that has two closet doors on it, close together (the king studs for the two openings are 13" apart). Unfortunately, they are aligned such that one of the 16" OC common studs would fall within that gap. In fact, it would only be 1/2" away from the left king stud, so not even anywhere near...

Regarding sleep quality, why did humans evolve to require full darkness?

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....

How often do I actually need my heat pump system tuned up?

I had a heat pump installed about a year ago. It came with one free service and the installing company has been calling me almost every week to come out and do the complimentary tune up. I know that I obviously should take a free tune up, but it made me wonder. How often do I actually need this done? What are they actually...

Do I Need to Watch Discovery To Enjoy SNW?

Hi all! Long time Star Trek fan here with my first post. I'm gonna start out by saying that I promise I'm not a hater of Discovery at all. It just has done nothing for me and from what I read, has not made any changes that would have solved my personal issues with it. I'm fine with others liking it and honestly wish that I did...
