you should be able to calculate the volume of the unit tetrahedron without help, if you're a real mathemati/sci/an
Oooh, I remember this problem from my Applied Triple Integrals class.

The area of an equilateral triangle of side length x is (x^2)*sqrt(3)/4, so, integrating along the altitude gives you sqrt(3)/12.

What do we use supercomputers for?
Weather forecast
Eroge.
>>7730918
Calculations that are incredibly massive, which can range from realistic graphics simulations (Read the Wiki article over the topic Fast Inverse Square Root), to weather forecasts, to population analysis and pattern recognition.
How do you prepare yourself for exams? :^)
I avoid courses with exams
>>7730677
Read the course reading. Do practice problems.
Depends on how much I struggled with the material throughout the semester.
Full review for anything with subpar regular exam scores, with a focus on the topics covered by those poor exams.
Something like Chem deserves a full review, whether you think you need it or not, but I honestly didn't have enough time for that this month. It had to take a hit for some math and physics review. I might have just barely gotten a rounded A in the course, if I had scored perfectly on that exam.
The last thing that you want to have rusty concepts for is Calc. You might be able...

So much for getting a B in calc III. You would never know I took calc III at another uni and got an A in it.

ITT We discuss the importance of taking extra humanities courses in addition to typical pre professional science courses (Pre-med in this case).
My School is considering this idea as well, but I don't know what it would mean for premeds. It looks like more courses as students would learn two disciplines and cram in required courses to be eligible for a post grad. It seems like a good idea for lawyers and ethics professors, though.
However, the article mentions core classes tailor made for...

Science may tell you how to clone a T-Rex.
Science tells you what a T-Rex is, and why it could be a bad idea to handle its kid improperly.
Science could tell you how to handle T-Rex specimens.
Humanities use concepts and tools discovered and/or invented by science and try to feel relevant when they are not.

>What would be your concerns or what attracts you to concentrating on both science and the humanities in an undergrad program.
I would be concerned about having to completely waste my time taking humanities courses.

Charles Weiner believes the sciences and humanities have become separated to the point that
"...future physicians must be more humanistic with additional skills in critical analysis, communication, and teamwork. The new MCAT being introduced this year addresses these cultural changes. The expectations of incoming medical students are becoming much broader to include cross-cultural studies, ethics, philosophy, and a range of humanities studies—all with...

Why are people still skeptical about climate change
Because you cannot fool all of the people all the time.
>>7716353
the politicians who are "skeptical" arent really skeptical. they have an audience/voter to cater to. those voters and their communities are the ones involved in and have jobs in oil, coal and natural gas; all the white trash hillbilly white folk who are retardicans. they have to take the opposing side to stay in power.

>Nobody important actually disagrees with me, they're just pretending to.
Pretty sure Cruz and others truly do not believe it.
To be honest I don't think it's as alarming an issue as it was talked about. Warming hasn't been occurring at the rate scientists were once predicting. Not even close to it.

I'm in local politics. Tell me about windturbine energy.
Are windturbines economically viable / profitable ?
Are they efficient?
Can they still be improved?
No, go with nuclear. Or invest in tidal power

The bad

Not OP, but it's well known that Python's array capabilities are only slightly slower than Matlab while Cython optimized array calculations (which most scientific distros of Python have built into the interpreter) are much faster than Matlab.
Also Python is faster to code in general.
I love MATLAB, but there is a good reason that Academia is jumping ship to Python.
Also we're all freetards by heart.

How does someone become a "golden boy" as a lot of people call it? Do you get a perfect GPA, go to universities with small classes, etc?
A golden boy as people seem to refer to is: Someone who is groomed and/or mentored by someone to actually become something in a field instead of a replaceable lab rat who gets burned from going into grad school.
What the hell are you talking about
you do not become one
you are chosen
It involves really actually caring about your field, and wanting to learn, explore, and do everything there is to be done in it. And yes, the bigshots are well capable of telling that apart from fakes.

/sci/ I want to play a game.
It's called which continent is more HARDCORE.
Okay, so we all know what can happen when you introduce a non-native species to an area. If they have no natural predators their numbers will skyrocket and they will take over everything and cause a domino affect affecting other forms of life too.
The rules are you could take any quantity of different species from a continent and introduce maximum 50 members of each species to another continent.
Which continent would lose their native population and get fucked up more...

Anyway I'll go first.
I say Africa.
North America's probably last because we're constantly getting fucked over by non native species.
Australia wins, and you know it.

Hey /sci/
anyone in here in the bioplastics industry? Or at least have insider knowledge?
I wanna do a back of the envelope cost-benefit analysis, TL;DR how many cents/lb to turn sugar into PLA pellets
>>7730571
No but I'm a chemical engineer. I can do a back of the envelope calc for you if I can find a general synthesis path from some commonly available sugar to polylactic acid.

AFAIK first step is just lactic acid fermentation, which would be almost free. But then there's the purification...
Comment too long. Click here to view the full text.
>>7730672
also wondering how high the yield of lactic acid would be from natural fermentation, problem being the bacteria just keep on fermenting until they die. I'm wondering if there's a way to extract or at least separate cheaply the sugars to keep the fermentation going until the bacteria just run out of sugars.
