Okay, guys. I am going to teach 4chan how to solve the 3^4 Rubik's hypercube using Magic Cube 4D. First, you must understand the basics which can be find here: http://superliminal.com/cube/solution/solution.htm
Might be tedious to read but just read enough to understand the basics and practice to get familiar with the hypercube.

I would also add you can change the colors of the cells by doing something like this:
>name a notepad file "facecolors" in the same place you keep the jar file and Magic Cube 4D stuff.

Anyone else find themselves straying away from STEM when they got into college? Heading into it I was dead set on engineering but the more classes I take the more I realize I find science and math tedious (not boring, I just don't enjoy the work anymore) and I really enjoy my politics and history classes. Thinking about switching to Poli Sci or Philosophy. Obviously will do grad school if I choose this, gotta get a decent job somehow. Anyways, is this a common thing? Switching from STEM from lack of interest, instead of switching from bad grades?

Pic always related,...

Switching majors like that isn't all too common, but you're fucking yourself in the ass if you steer away from STEM, anyways. That shit's good money if you're good at it, even if you don't necessarily enjoy it all the time. You might be a slightly happier deadbeat, but a deadbeat's still a deadbeat, you deadbeat.

I honestly want to do something with film. I realize that its a risky thing to do but I would honestly rather waste my time trying and failing then not trying at all. I would settle for being a fucking gaffer honestly.

That brings me to my next question, do any of you STEM people ever regret getting into it for just the money? I know a lot of you probably enjoy it but I am sure there are some cases of people being persuaded into it when they had no real interest in science or math.

This is related to your level of anxiety. The more anxious you are, the more likely you will come to your computer and play games, watch videos, etc. Take "natural" chess players, those who do not study game theory nor chess theory. They are incredibly anxious, they say: If I am going to learn chess, might aswell just play it.

Take less stimulants, take some moderate alcohol instead, meditate, and you will see that physics and mathematics are great. Stop being an anxious ape. Everybody like history, just like every kid like magic.

A new meta-analysis by the University of Vienna, University of Goettingen, and Tilburg University has confirmed a small association between brain size and IQ, independent of age and sex. The study concluded that brain structure and integrity are more important factors.

Some facts:
- In 1836 German physiologist Friedrich Tiedemann linked brain size to intellectual power.
- The sperm whale has the largest central nervous system by mass.
-- Controlling for body weight, the shrew has the largest.
- Men have larger brains than women, but there is no IQ difference between the sexes. (Debatable. Rushton thought there was.)
- Megalencephalic individuals (who have larger brains) have lower IQs than average.

I explained to my friend the theory of relativity and how it can basically be used to time travel, he didn't know anything about it earlier, but he came up with this idea. I'd like to hear your thoughts on it. We take a "train" or tube something of that sorts and we speed it up in a huge underground track to a very high speed, the fastest we can get it. Then we have the tube around it, with it moving, also put to that speed, so relative to the earth it's moving twice as fast as we possible can move it now, we continue this process untill it's fast...

Relativity does say that if you move an object or piece of information from one place to another faster than light it is effectively time travel, because that object could be observed from some frames of reference to have arrived at its destination before it left.

That said special relativity also specifically says that it is impossible to accelerate any object beyond light speed as it would require infinite energy. General relativity makes room for some possible loop holes that get around this by distorting...

I'm a first year math student.
I'm doing well when it comes to pure math. I understand it, can do proofs, get good grades.

However, I'm shit when it comes to applied math - even the most basic. I often run into equations and exercises which require novel (for me) approaches, and I just can't solve them. I then have to ask other people how to solve them, and I could never think of the approaches they used on my own, even though I understand them.

How do I get better at applied math? Do I just do a shitton of exercises, until I get familiar...

> “Oh that's popsci; That well never happen within our lifetimes.”
It's popsci because there is no basis or anything constructive about their mechanics that are discussed in the threads. Someone watches some stupid movie and thinks they are ready to get into a scientific discussion that are supported by facts and logic rather than fantasies and autism.
>>
>>7588950
>facts and logic
I might sound autistic then; aren't almost all current scientific theories technically ideas? Theories aren't set in stone; can't theories be disproven? There is no evidence to prove the existence of Worm-holes nor is their evidence to prove they do exist. But to toss out an unproven concept instead of debating it. Is just not in the best interest of science.
