Hey, /sci/, it's /tg/. I'm making a setting which can shortly be summed up as "Atompunk" and I need some advice on how to treat nuclear reactors.
Specifically, in an alternate world, the Kingdom of Astaria was once a typical Steampunk kingdom. Problem is, they ran out of coal. Due to lucky placement of a few geniuses, they quickly learned of radioactivity and its . The first Uranium pile was put into place in 1903, and the first Thorium Molten Salt Reactor built in 1907. These are concessions to the idea of Atompunk, so I'm not asking about them, or the miniaturization required.
What I'm asking about is the basic mechanics: If you have the capability to build a three megawatt reactor that lasts for six years, can you build a similarly sized or smaller three hundred kilowatt reactor that lasts for much longer, or do things just not work that way?

/sci/, this is something that has been puzzling me for a little while now.
First, let's assume that technology has advanced to a point where a functioning human brain can be replicated through mechanical, synthetic, or some other means. This process is precise down to the point where a brain can be created in an identical state to an individual's at a given point in time.
Functionally speaking, someone could have their entire brain transplanted with an identical one in an operation, "they" would wake up and it would be as if nothing changed by their perspective, however theoretically speaking this would be a new, identical person and the one who entered the surgery will die. (In the scenario that the original brain is discarded and not transplanted elsewhere.)
Taking this into account, what would happen if the same procedure was executed in parts instead of a single operation? Is it possible that to replace an entire human brain without "killing" the original consciousness of that brain? If not, at which point is it lost?
How Much Math Do You Use?

I was chatting with nuclear engineer the other day about his job and degree and after telling me about the mathematics courses he took in college--Differential Equations, Partial Differential Equations, etc.--I asked how often he used that kind of math in his day-to-day work. To my surprise, he said he virtually never used any of it. In fact, he claimed the highest level math that he had to use over the past several years had only been some stuff from Cal II.
So to all of you STEM majors: What's your job and degree and how much of the math that you studied in school is actually put to use in your day-to-day work? What kind of techniques do you use regularly? Do you ever find yourselves in a position where you have to crunch out some of it by hand, or is it all done on a computer program or a calculator?
