What should I read to understand math really well? (Anything past high school. I know calculus but I want a deeper understanding than what they taught at school.) Is pic related as good as people say it is? I really like the cover. (inb4 don't judge a book by it's cover. Sorry, I'm very lookist.)

Long paper (very short book?) explains a lot of good stuff about math. Starts with Euclid and goes up through high school with an advanced application at the end.

Fractional Distance: The Topology of the Real Number Line with Applications to the Riemann Hypothesis
https://gofile.io/d/gV8m2B also https://vixra.org/abs/1906.0237

ABSTRACT: Recent analysis has uncovered a broad swath of rarely considered real numbers called real numbers in the neighborhood of infinity. Here we extend the catalog of the rudimentary analytical properties of all real numbers by defining a set of fractional distance functions on the real number line and studying their behavior. The main results of are (1) to prove with modest axioms that some real numbers are greater than any natural number, (2) to develop a technique for taking a limit at infinity via the ordinary Cauchy definition reliant on the classical epsilon-delta formalism, and (3) to demonstrate an infinite number of non-trivial zeros of the Riemann zeta function in the neighborhood of infinity. We define numbers in the neighborhood of infinity as Cartesian products of Cauchy equivalence classes of rationals. We axiomatize the arithmetic of such numbers, prove all the operations are well-defined, and then make comparisons to the similar axioms of a complete ordered field. After developing the many underling foundations, we present a basis for a topology.

How the fuck is this shit still a thing? There is literally no treatment. What the fuck do scientists do all day? We need to lock them all in a room and start going through all the diseases of humanity one by one and if they don’t figure it out within a year we start killing one scientist a day. We’ll go in descending order of disease sufferers, so we’ll reach tinnitus in not too long.

can you fuck up the natural processes of your body by drinking too many energy drinks? I drank them everyday for a year, after finals week i stopped drinking all energy drinks and feel like shit all the time and its been a month too. i occasionally drink a cup of tea which makes me feel better but over all feel like shit. is it something to do with my heart?

Not with redbull, it is just sugar, water and caffeine basically
Not sure about rockstar or monster, they have many more ingredients, I assume it should all be food grade stuff and safe to consume moderately (even if daily) but I don't know for sure.

Caffeine is addictive and will absolutely make you feel like shit when you’re withdrawing. I can’t speak for whatever other active ingredients they put in those things. You just need to stick it out, anon. You’re quitting cold turkey but it will be worth it in the long term. Those things are not healthy for you.

>>11883018
Try consuming Ginseng or Taurine, that might help
>>
>>11883018
Not more than coffee with sugar.
Ginseng is a meme and so it taurine. Not that it doesn't have some positive effects but their intensity is grossly over exaggerated. It can happen regardless though that your body adapts to a daily intake if it's high enough. In this case just wait it out for 2-4 weeks.
>>
>>11883018
It's just caffeine. There are a bunch of vitamins and random crap like taurine but they don't do much. You wouldn't notice a vitamin deficiency immediately.

>How useful do you think computational chemistry really is when its applied to medicinal chemistry
I'm not a computational chemist, but I work in medicinal chemistry and we use software to model drug-protein interactions fairly often. It's kind of how you describe it here
>the best approach always seems to just make a library of compounds and do the biological tests first, and then use computations to confirm binding to protein targets rather than the reverse
I'm sure how it all works, but they after identifying an active compound they get the crystal structure of the protein + substrate and can "dock" new substrates that are similar into that crystal structure.
It's only ever a loose aid, though. It can give you an idea whether an alteration to the molecule is good or not, or what interactions are responsible for activity.

To my knowledge, you can use FEM and FDM to solve for specific pdes once you've constructed a data set from DFT. What do you have in mind?
>>
>>11884235
Probably something along the lines of what >>11877843 said, long term. I'd imagine it isn't that useful for structures such as polymers or glasses.
But short term just getting a solution to some arbitrary problem would be pretty cool too.
>>
>>11884426
You can try a small system perhaps. Maybe silicon or FCC copper. DFT is very good at getting energy values so you can derive things like effective mass purely from DFT energies by solving a second order pde using finite differences. A common one people are always doing is solving transport properties using Boltzmann transport equation.

I spent quite a lot of time rubbing my brain cells together in order to make this. Just follow the instructions in the title: Click the blue line when it appears, press Alt-t, Alt-1, H. Phone users btfo.

The more I learn, the more I realize the absolutely mindbogglingly insane conditions that had to coincide to create intelligent life on Earth.

First, Earth itself is a rocky planet, with just the right "Goldilocks" distance to the Sun to support liquid water, with just the right material composition, with an orbit that has very low eccentricity, located on a solar system that is stable, with Jupiter acting as a shield against interstellar asteroids and debris, and it also happens to have a disproportionately large Moon that serves to regulate the tides, which allowed life to emerge on tidal pools that otherwise wouldn't have formed.

Not only that, but Theia's collision with an early Earth helped to shift its axial tilt to a position that creates mild-ish seasons, and also served to slow down Earth's rotation from 10 hours to 24 hours.

Then, after the emergence of life, there were several extinction events that could have gone very differently, either wiping life altogether, or not wiping it out which would have led to life on Earth being very different. The right conditions just so happened that favoured the disappearance of the slow-witted, titanic dinosaur life of the Jurassic and favoured the evolution of smarter, smaller animals like birds and mammalians, with larger brains that consume much more oxygen but smaller bodies. Out of all these mammalians, the right conditions favoured apes to climb down from the trees and move to the Savannas, which again favoured larger intelligence as socialization became a requisite for survival in the large hunter-gatherer tribes of early hominins. Out of all these different types of hominins, Homo Sapiens managed to win out the evolutionary game against Neanderthals, both competed for the same food sources and (roughly) habitats, but it was the Humans that managed to win and drive out the Neanderthals to extinction in no small part thanks to our domestication of dogs which gave us an edge in hunting.

>Does economics belong here?

I have taken up self study on economics. I took titles of all recommended books and articles off MIT OCW. My original intention in getting the textbooks was to find PDFs and pull original sources off of them and then weed out all of the textbook filler. Aside from inline examples there aren't sources. This isn't such a big problem. I noticed that later graduate courses really hinge on examining actual events, case studies, and articles. Big plus and they are already organized by topic. Seeing as the MIT textbooks do not provide what I seek, I am looking for an economics book dump. Math included is not necessary, but is also fine. Economic philosophy is a big plus as well, I have no clue of what to look for outside of pop econ.

Daily reminder economics is not a science, and even if it was, it would not be worth funding institutionally as
1) the predictive validity of dilettantes in the field is just as strong as experts
(pic related)
2) You make better return on investments if you treat experts in the field as anti-experts (invest in the ones they say are crap)
https://didattica.unibocconi.it/mypage/upload/154156_20170919_051604_DIAG_STOCKS_BGLS_NBER.PDF
3) economists cannot reliably predict a recession more than 2 months in advance
https://onlinelibrary.wiley.com/doi/abs/10.1002/bdm.3960050306
