Can a chemical be a meme? I would say the following chemicals are memes:
Sulfuric Acid
Hydrochloric Acid
Nitric Acid
Citric Acid
Acetic Acid
Sodium Hydroxide
Sodium Chloride
Iron (III) Oxide
Magnesium Oxide
Copper Sulfate (and •5H20)
Hydrogen Peroxide
Barium Chloride
Methylamine
Formaldehyde
Ammonia
Ethanol
Acetone
Carbon Monoxide
Carbon Dioxide
Ozone
What are some other meme chemicals?

H fucking F. Fuck that meme acid.
Also fluorides in water.
I fucking hate fluorine.
Define 'meme'
Helium
Why don't universities offer a history class for mathematics and the sciences?
You know, for people who arent going to be history, social studies, english or art majors.
What? When you said "a history class for math and science" I thought you meant a history OF math and science, which most universities will have classes in. But then from the second sentence I don't know what you're talking about.
>>7742079
There are classes on the history of mathematics.
>>7742087
I think OP meant courses like a history of mathematics course covering stuff in modern mathematics aimed at math majors. eg.
>Such and such theorem originally came about because so-and-so was trying to figure out X.
>Later on these other guys realized they could generalize it and the breakthroughs led to the theory of Y.
I don't know, OP. I imagine it's because there are typically many professors on staff versed well enough in the history...

>Upon starting high school, Feynman was quickly promoted into a higher math class and an unspecified school-administered IQ test estimated his IQ at 123[20]—high, but "merely respectable" according to biographer James Gleick;[21] when he turned 15, he taught himself trigonometry, advanced algebra, infinite series, analytic geometry, and both differential and integral calculus.[22] Before entering college, he was experimenting with and deriving mathematical topics such as the half-derivative using his own notation. In high school he was developing the mathematical intuition behind his Taylor series of mathematical operators.
So, based on the above passage, do you have an IQ at or above 123?
IQ doesn't mean much
>>7741726
>he taught himself trigonometry, advanced algebra, infinite series, analytic geometry, and both differential and integral calculus.
I did this too, it's not very impressive and doesn't mean you're particularly clever.

Why haven't you gotten a Nobel yet?
New supermetal?
>Here we show that a dense uniform dispersion of silicon carbide nanoparticles (14 per cent by volume) in magnesium can be achieved through a nanoparticle self-stabilization mechanism in molten metal. An enhancement of strength, stiffness, plasticity and high-temperature stability is simultaneously achieved, delivering a higher specific yield strength and higher specific modulus than almost all structural metals.

>5 years ago: "Alloy"
>Today: "NANOTECH SUPERMETAL"
>>7741636
Is there any reason this technique couldn't be applied to other metals for similar results?
>>7741636
>14 per cent by volume
Juden pls
>>7741651
Yeah, there's been a ton of research in nanoparticle inclusions in different matrices, metallic and otherwise. I'm guessing this one got in Nature because

Are there any botanists here? Where do you go for research?
I'm trying to determine where the tetrahydroisoquinoline (eg salsolinol) present in theobroma cacao seeds, actually comes from. I don't think it's synthesized by, or a metabolite of, the tree / fruit itself. It seems more likely it occurs from fermentation after harvesting, but I don't know.
I've just been going through pubmed and Google scholar, thought there might be a better resource. I also can't find high quality and complete studies detailing the average composition...

Also, has anyone ever eaten a cacao fruit itself?
Do you go to a university? If so, see if you can access your library's online databases. Most colleges have bought access to EBSCOhost.
>>7741492
I don't.
I'm also curious about the presence of caffeine. Many studies report it is present, but some do not, and suggest it stops short of synthesizing more complex methylxanthines. Which is why most of its content is theobromine and a bit of theophylline.
Could nuclear war ignite the earths atmosphere?
[See hysteria 75 years ago]
>>7741290
About the only thing in high enough quantity in the atmosphere for oxygen to burn with is nitrogen and other oxygen. One creates ozone, the other would be laughing gas. Neither system is favored by thermodynamics.
There is an infinitesimally small possibility. Very very fine dust particles are explosive.
So /sci/, why do we laugh?
I can imagine its a signal that we're in a good mood or having a good time
But why do we laugh at certain things instead of others and why does everyone have a different sense of humor?
We laugh when something is funny.
>>7741796
Thx man it all makes sense now
we laugh to fend off attacks from predators when we're caught off-guard.
Seriously imagine you're an animal and hear humans laugh like fucking hyenas
Ask a medical physicist anything.

bribes? tell me more
What's it like knowing your two fields of decent specialization are on entirely different levels of development?
What field of study ISN'T a meme these days...?
Nanotech and Materials
Any engineering field or mathematics.
But mainly, do what you want that is economically viable to pay off your debts and help you remain self sufficient.
>>7739874
None. Studying IS a meme.
How do I learn the "science of deduction" like Sherlock Holmes?
>inb4 he's fictional character, I said "like"
>>7739240
Get a degree in memeology.
>>7739242
Me:I have that. Ph.Deez nuts
Barber:come over
Me:why you always lying?
It's called logic which is part of philosophy.
Should engineers get there own board? Obviously math deserves it's own board however there's enough justification for keeping science and math together.
I hate the idea of giving engineers there own board but the amount of shit posting they do here shows that we need a containment board for them.
>>7738840
This board is 99% undergrads and high schoolers. The difference between engineers and scientists at those levels are negligible.
>>7738840
Why would someone do that? (your pic)
>>7738840
oh look yet another shit thread made by some kunt whining about engineers
I bet you're the same guy as well
What are your study methods?
Write out every equation I need to know. Write them out about 50 times each at least. Go through practice problems and repeat
>>7738064
How well did it work so far?
>>7738064
Jesus. Sounds ugly but decent-ish for see/do classes like elementary calculus. Something like this will do you no good for higher math.
For me, I like to write down only definitions, propositions, theorems. No proofs. Very few examples / exercises. Then I go through my notebook a couple of times each semester and try to prove everything and think of examples. If I can't, I failed, and I study that topic from a book and try again.
Can an engineer be deluded enough to actually believe he is as important as a scientists?
I mean thats like an oomba loompa thinking hes just as important as Willa Wonka isn't it?
>>7734558
sounding logic m8
>>7734558
I don't think engineers care. Engineers are too busy getting laid and paid.
>>7734568
You mean sucking dick and buying their own groceries.
STEM. Science, Technology, Engineering, Math
Science - /sci/
Technology - /g/
Engineering - /diy/ /hm/
Math - /mat/
Math really ought to have it's own board. Its not fair the engineers get two.
>>7741428
>/sci/ - Science & Math
math has a 1/2 board thats all it needs because nobody cares about math
if people really wanted to discuss math there would be more math discussion here
>>7741434
I think math undergrads are a very important demographic in /sci/, at least from what I've seen.
Without the math /sci/ would be nothing but /x/ and /adv/
What would happen if a nuclear bomb exploded inside a gas giant?
When we have the technology to do so, would the experiment justify exploding Jupiter?
>>7741416
That is an interesting idea. It is mainly hydrogen and helium so if we drop a nuke and super increase the temperature, we could have fusion occurring which would hopefully start a chain reaction? There is the question of pressure tho
it's too small to sustain deuterium fusion, so it can't even become a brown dwarf iirc.
