Why are they so awesome?
>>8468336
Because russian mathematicians are awesome. Mathematics was always like a popular sport for russians and they had many clubs where children learned math after school. Unlike other sciences the russians didn't shorten the sponsoring for math during WW2 and the cold war (the government didn't understand the math and didn't find traces of dangerous mindset, kek). That's why people like Perelman had a chance to develop their talent.

I'd like to take a Linear Algebra in Python class next semester and I want to study on my own before I actually take the class.
Does /sci/ have any preferred college-level textbooks I can use to supplement online studying?
anton's elementary linear algebra
Use David Poole's book. It's the only book I've seen (besides the one that you posted) that has good reviews.
Other decent books are:
-Hoffman
-Berberian
-Leon
-Shilov (personally don't recommend, but people like it)
>>8466467
as far as engineering-type algebra classes go the book in your pic is great.
i did an algebra for physics class and it was perfect for 70% of the course .
Why is pi so revered while nobody gives a shit about e? I have never seen 50 digits of e plastered along the wall of a math office or people trying to memorize as many of its digits as they can, yet I've seen it for pi.
Is it just because most people know about it because "hurr hurr pie?"
>>8463579
e is pretty revered among college students. Probably more so than pi. But pi is obviously slightly more accessible to the public so outside of college you hear more about it.
the first digits of e are actually easy to remember
2.718281828...
You can't bake an e on e day fucktard
What are some chemistry experiments I can do at home?
Fine. Science is dumb anyway.
Bleach + ammonia.
Fun stuff.

The domestic cellulose combustion experiment.
Apply heat and oxygen to the load bearing cellulose members of your dwelling, you won't believe what happens next!
Hi /sci/,
Is there any body of scientific work that you know of which looks at exploring metaphysical concepts such as the soul or related spiritual concepts?
>>8459612
theres a guy called sam parnia who does studies on near-death-experiences for the sake of medical research... the popular media interprets this in terms of life after death, souls etc but it really isnt... however you can think of it that way if you want!
PIC RELATED, IT'S DONE, OVER, KAPUTT!

Sorry if this is not a particularly liked subject in /sci/, but I'd like to ask. I'm almost at a point where I can apply for specific programs on the B.S. level. When I was young, I wanted to become a scientist, and if I was capable of doing it, I wouldn't be opposed to doing it (maybe in my later years). However, when looking back at many of my biology classes, I noticed many of my professors were Ph.D's, had done research for some years, and then went into teaching. When I was talking to those professors, one taught entry-level biology, one taught microbiology, and the other taught microbiology (I had to retake microbiology because I could not handle the honors class at the time), that they mentioned having to give up research after a certain point.
A lot of these women were older, with the youngest one having gone into grad school around the age of 24 and a half. My professor did encourage me into considering research when I was talking to her about struggling with some concepts. When I was at a line for an event, I spoke with another female grad student (her study was ophthalmology). A lot of them decided to go out of research once they started having families and they talk about leaving with some pain.
I understand that grad school and beyond is very stressful for everyone, and more or less you have to dedicate your life to it, and I'm not quite cut out for that at this time. But why is that? Why as a society do we have such a narrow focus on upper level academia, with very limited funding? Why is a lot of the medical field very haze-mentality in the way it treats students? Why is grad school so grueling? I know that you might have very strong opinions, but I'd like to ask because I've never viewed it directly, but from afar. Please don't judge; these are very bright women that I know, and they certainly did enjoy their time in academia, but if anyone wanted to give insight about grad school lifestyle or research, it would be appreciated.
>>8470933
It's not a career-asking thread. It's asking about why academia is not conducive to a healthy mental life or personal life.
>>8470928
So which question do you want answered? All we can see is a convoluted blogpost that doesn't get to the point of your query. Mind rephrasing in a few sentences instead?
>>8470939
1. Why does academia get next to no funding?
2. Why is grad school, doctorate school, and medical school so grueling and not conducive to a family life?
3.If you are female and in a stem field, do you feel that your program or focus does not have an anti-maternal attitude?
4. If advanced programs have such a high divorce rate, why does no one seem to care?
what are the best subjects to study for the asvab
>>8469294
Practice doing basic math by hand. By basic I mean everything before calculus.
Some calc/physics knowledge doesn't hurt.
Beyond that its SAT knowledge of science and grammar/vocabulary and a little bit of knowing the parts of a car engine.
The practice tests are representative.
doing pushups, saying "Yes sir,", practicing "i don't know but i've been told" songs, huffing cs gas, waking up at 4 in the morning, showering with cold water for only 2 minutes
>>8469317
lol
>/sci/ says CS is easy as fuck in uni
>believe them
>take shitty OO programming course in java
>get rekt
>doing fine in all other classes
>>8469268
Same here. I might be stupid but I think it's really just that I couldn't care less about all the stupid details. And not to mention reading a cs textbook produces tangible sensations of dissociation.
>>8469268
It is so easy that any nonbrainlet gets too bored trying to study it, that's why they get rekt.

I beg anons to teach me about reactors and the feasibility of converting a Farnsworth Fusor into a nuclear reactor.
I'm thinking lead is the best coolant because it doubles as radiation shielding.
Either uranium or thorium is fine. No clue which is cheaper.
I do not know what the most affordable neutron source is, but I would prefer to not need a breeder reactor to save weight.
I also do not know of an affordable neutron absorber that's efficient enough to halt the reaction.
What laws and agency regulates nuclear reactors? Pls help.
Also, which solid form of mass has high compressive strength and is the best at not conducting heat? It needs a high melting point for safety.
Any word on how fusion reactors are progressing?
>>8469236
Fusion is notoriously difficult to keep sustained. But there is a pulse nuclear reactor.
Millions of tons of metal salt in underground insulated silos. Detonate a small fission or fusion bomb, it heats up and melts the metal salts. Then you use a heat exchanger to make electricity.
It might work at smaller scales and less destructive energies.
>nuclear reaction makes heat
>use Carnot cycle to extract work from the heat
There you go.
Also, TRITIUM IS $30,000 A GRAM.
Could you turn a Farnsworth Fusor into a tritium breeder? What purity would you get? How do you refine tritium? Could you make a tritium reactor?
>>8469262
Which heat diffuser is best for space applications? Nuclear power lasts longer than solar panels in radiated parts of space. Too much sunlight deteriorates solar cells as well.
For land applications I was thinking of using boiling lead. Condense it back down after the boil and you've got a coolant that works as a rad shield. Safety first.
Plus lead can solidify and plug leaks on its on depending on the location.
Also, why does Wikipedia know almost nothing about molybdenum carbide??
I'm looking for the lightest and strongest metal with a very high melting point.
Is it a good idea to line the inside of the reaction chamber with refractory metal ceramics?
Its a small reactor.
Very small.
Why does anything smaller than planck lenth makes no sense?

yea pretty confusing bc your dick is 10^-36m

It does make sense, planck length is a meme.
What is the tangential angle for a point at some distance down the Archimedes spiral?
pic related
>>8468759
is it even defined?
what is it on a circle?
>>8468759
wat
>>8468759
Tangential angle is always zero. That's what "tangent" means.
What can you realistically expect to do in life with a math major.
300k starting salary?
more like 30k.

Finance seems like a meme degree. I'll be going to a state school. Seems pointless if you don't go to an IVY.

Stop this meme.
