Where does Autism come from? Could it be vaccines, plastics, automobile exhaust, electromagnetic radiation, pills during pregnancy, lack of maternal warmth, or etc.?

Autism doesn't exist. The meme comes from schools wanting something to blame for kids not being well adjusted.

This. Couple of days back at work I was asked by a co-worker how I learned programming. He specifically asked 'What books' and I was like what the hell. I learned from a website.

That said, some goods are just too good my man.

CL FUCKING RS. Introduction to Algorithms motherfucker. Before reading this I was a block of rock and after it I was chiseled into Michelangelo's David when it came to my knowledge of computation.

I know that legally a person can do an undefined numbers of degrees. But how much can a human mind handle?

There is no limit. You could just keep doing them one right after the other and you would never come at a point where you could not keep going.

And if you mean at the same time, probably 3 but you have to be autistic and have no social life.

Other than that, it should be illegal to even do double majors and it should also be illegal to go back to university for a second degree (of the level) before at the very least 5 years in industry, specially if your education was funded by financial aid programs.

I find it funny how we have academia babies who would rather waste their time doing a double major instead of using that extra time and energy they seem to have to work part time or to do solo projects and shit.

Waste of human "talent".

if you can handle a degree you can handle all degrees of that 'level' .why would you fucking choose to do so is another thing entirely .
just go for a degree in whatever you find most interesting and read books of whatever other subject you find interesting .
that way you can fuck around and study the other shit at your own pace and maybe go to a course or two if they have a really good professor or something .

studied chemistry that way with a totally bro chem professor while doing a physics degree .

Okay don't crucify me for this.

In the latest ancient aliens episode, they mentioned that some scientific reports shows that if you subject mercury to a very high level of eletrostatic charge and then spin it, you get a gravitational thrust which allows you to create inertial force that can counteract the gravity.

Is there any truth behind this ?

There are two identical objects, i apply 5 newtons of force on the first and it moves, i do the same to the second object but it doesn't move, the chance of this happening is non-zero, in this hypothetical situation if the cause of the first objects movement is applying the force then what is the effect of the force application on the second object if the two objects are stationary?

Wrote this because saying the force application causes the object to do nothing doesn't make scene to me because it was already doing nothing,
it's like saying the object does nothingx2. These two objects have the same mass.
>>
Or is it the case that 100% of the time two identical objects will react the same if tempered with in the same manner?

Hello /Sci/ I have a simple challenge for you.
If I have a 10ml vial and 2.5 mg of a substance with a molar mass of 209.29 how much water must I add into the vial to fill the vial to 10ml, no more no less.
Let's see if any of you actually paid attention in your Chem classes.

A programmable lego or kinect set? Idk. Most mechanicals I saw were working on simulations in matlab and shit. They really didn't do anything intricate, just reviewing real physical properties (stresses and such) and production methods. I almost forgot production, they did a lot of that side. Different types of physical and chemical bonding, lots of shit. Look up your universities curriculum.

How do you deal with the fact that you went to a non Oxbridge / MIT / Stanford / Caltech / Ivy League university and were surrounded by anti-intellectuals and had a much less rigorous curriculum for the entirety of undergrad?

It feels fucking awful to me. When I see giant university buildings I am in disbelief. These are monuments to a broken society that celebrates mediocrity.

>How do you deal with the fact that you went to a non Oxbridge / MIT / Stanford / Caltech / Ivy League university

By not caring. There are opportunities everywhere for those smart enough to look for them and at this point I can tell you that I have gotten more professional opportunities as a student than most of the people at Harvard ever will.

I mean, how common is it, even for Harvard people, to get internships related to their education from their freshman year? I will be generous and say at most 50%.

> by anti-intellectuals

Average people are not anti intellectuals. Also, if you want to talk about intellectuals then just google the shit that happened at Yale, which is Ivy League.

>The point is not to make an intellectual space, it is about making a home here!

I am paraphrasing that but it has been months since I saw that video, so fuck it.

Is that the kind of 'intellectual' you admire?

If anything, that proves that it is not the university that makes the student, it is the student that makes the university.

That girl was surrounded by the supposed best of the best, and yet she came out shit.

They had some problems inflating the expandable module yesterday. Probably because of higher friction of the materials than initially expected.

Trying again today.
they're releasing short bursts of air into the module and wait for it to settle and then release another short burst.

Faster to learn, faster to code or faster to execute?

If you have some programming experience, MATLAB should only take a few weeks of solid work to get the hang of.
