how the fuck do you decide what you will study for the next 4-5 years? this is insane. what if you lose interest?

i'm interested in superconductors, CPU architecture, heat exchangers, propulsion systems, chemical explosives, protein synthesis, nonlinear PDEs, energy storage, machine learning/cryptography, lithography/crystallography, electroactive polymers, josephson junctions, multijunction solar arrays, all both in theory and in application. am i fucked? some anon here said do material science, electrical engineering, or physics. pic related.

This might sound like a retarded question.

But how does one gather as much knowledge as possible within like 4 years.

I've got the time, I've got the motivation. But I don't have a plan where to start.

With knowledge I mean actual knowledge like math, physics, chemestry, biology, history, geography, languages etc., not stuff like "Who is married to Angelina Jolie?"

I'm getting into formal and rigorous mathematics and I'm looking for a book on proofs, axiomatic systems, and set theory. My only exposure to axiomatic systems proper was in a rigoros euclidean geometry book, and set theory was breifly explained in baby rudin, but I'm looking for a book that deals more thorougly with these subjects.

Pic is what I've been looking at, but I'm not sure if it's any good.

Also as a sidenote, am I correct in my understanding that "axiomatic system" is basically what we mean when we say "rigour"...

That's a really nice text, anon.

So should I try to look into books on set theory and logic separately? I noticed the text does give a number of example works, if I go through the text and read through the books recommended (As well as maybe reading an intro to proofs book), would I be well prepared for the more rigorous parts of mathematics?

Why are so many people obsessed with colonizing Mars?

Even if we can melt it's ice and make it warmer it's going to be losing atmosphere due to weak magnetosphere. And it's gravity is unhealthy for humans.

Can any geologybros help me identify this rock? I'm only a first year so I don't know shit.
It has well-defined layers that go all the way through and it's partially coated in what I think is bitumen (or whatever it is they stick roads together with) and I found it on the way into a field that had been surfaced with broken chunks of tarmac. There were other similar rocks nearby.
I gave it a few whacks with my hammer and the rock didn't break and sparked once. The fracture looks vaguely conchoidal but without the arcs you'd see on flint. Couple...

So today I learned that americucks weren't learning about pic related until their master because it was "too hard to understand". Is it why engineering is seen as a fedora-tier education in the US?

>would we of definitely observe them by now?
We could only answer this question accurately if we had experience with galactic societies.
You're asking a question we don't have enough real-world experience to answer.

Perfect example. Why would you assume this?

Yeah that, because if they were years ahead of us they probably would have developed TV one stage in the history if they eventually built starships wouldn't they? But the image of near by aliens watching 50 sitcom is unlikely then?

Not 100% sure, but the water around the cup will never get above 212F (boiling point of water). Maybe they are saying that the water in the cup can shed it's heat out the top of the cup faster than heat from the boiling water can enter through the non-zero resistance of the walls of the cup?
>>
>>7761699
>212F (boiling point of water).
the boiling point of water is 100 degree celsius.
>>
Not sure if thats true but as soon as water reaches the boiling point(depending on airpressure) at 100°C, it wont become hotter. it will stay at 100°C. The cup keeps the temperature of the water in it always slightly below 100°C.
