How do I become a genius? Someone informed on about everything and can use scientific reasoning to figure out the best solution to a problem. Where do I start reading? I have just realized that internet articles and YouTube videos probably aren't enough to learn about math and science. Where do I start?

If you think Rick Sanchez is a genius then I have to say: you are 100% intelligent and capable of being a genius.

To become a genius you need to enhance your brain. Our brain is usually made of weak material but you can enrich it with stronger material like metal. So just grab a gun, put it against your temple and pull the fucking trigger.

Help. How do you find the total charge in a charged sphere with a variable permittivity? This shit is nuts.

Pic related is the permittivity function.

Forgot to add that 'a' is the sphere radius, 'r' is an arbitrary radius inside the sphere, and Epsilon1 and Delta are known constants.

another thing,
I am attracted to a really attractive woman, and a part of me tells me she likes me back, but I feel like she's too good for me

Did it work for you?
I had a perfect diet yesterday.
I started feeling cravings today in the afternoon and I couldn't take it anymore.

I know that eating sugars is ruining me.
Me teeth, my skin, my hairs, my brain, etc...
I cannot stop though, it's like I don't give a fuck.

I am an addict.

What kind of devices, electronic or non, does /sci/ use to work through problems? I'm thinking of getting a older thinkpad tablet or chromebook (/g/ meme) and throwing Debian on it (set and forget). I just need something basic to work out problems at this point. Not really into surface pro or ipad pro personally. I've also considered getting a large freestanding whiteboard or chalkboard for my spare room. I don't really need anything like version control or OneNote status at this point.

In the previous term in my college I had to learn how to write simple code in Vim & basic command line for Linux.
It's ok, and very minimalist.
But Are there any better option than Vim & Emacs that I can use a mouse instead of only keyboard?
Sublime is proprietary. Atom & IDEs are fucking slow & bloated. VS Code is a spying botnet.
Any alternative minimal as Vim but with a nice grafical interface?
>>
>>9111335
maybe texmaker or texstudio or some similar will work for you
try googling for open source editors for latex and trying some to see which you one you like the most, in the end, it is only personal preference and adaptation

I don't have much practical experience in chromatography yet. I'd like to know how effective separation based on boiling point is.
I'm trying to find a suitable stationary phase for quantitative analysis of pic related. Was thinking WCOT dimethylsilicone with a small degree of phenyl substitution to get some selectivity for the aromatic compounds.
But I'm facing a problem with the 2 bottom ones. They have near identical boiling points. Would turning them into enol ethers solve my problem?

Also general chromatography thread hoera.

I bet all of these things separate cleanly by GC for analysis purposes. I bet you can just read up on your favorite GC supplier's website about which of their columns is best for aldehydes.
>>
>>9111080
have you considered HPLC? Otherwise GCMS should do the trick
>>
>>9111326
I guess, this is where the whole practical experience thing would help heh
>>9111626
I have, reverse phase HPLC could work but I'd have to figure out a gradient for the mobile phase because there's no way I'm getting a good chromatogram for these with an isocratic mobile phase
I'd already picked GCMS because these compounds are volatile and since we're looking to quantify only 5 compounds the MS could be set to selective ion monitoring for the M+1 molecular ions (using chemical ionisation)
with splitless injection and solid phase micro extraction that should allow for quantification in ppt-ppb levels

Lysenkoism (Russian: Лыcéнкoвщинa, tr. Lysenkovshchina) was a political campaign against genetics and science-based agriculture conducted by Trofim Lysenko, his followers and Soviet authorities. Lysenko served as the director of the Soviet Union's Lenin All-Union Academy of Agricultural Sciences. Lysenkoism began in the late 1920s and formally ended in 1964.

The pseudo-scientific ideas of Lysenkoism assumed the heritability of acquired characteristics.[1] Lysenko's theory rejected Mendelian inheritance and the concept of the "gene"; it departed from Darwinian evolutionary theory by rejecting natural selection.[2] Proponents falsely claimed to have discovered, among many other things, that rye could transform into wheat and wheat into barley, that weeds could spontaneously transmute into food grains, and that "natural cooperation" was observed in nature as opposed to "natural selection".[2] Lysenkoism promised extraordinary advances in breeding and in agriculture that never came about.

And non-European immigrants could transform into productive members of society.
