Why does he even care that much? The money wasn't even involved anymore. He just needs to ask google for a fucking .exe and he can play alpha go as much as he wants.

Yeah I can't see how he could be so angry/depressed/annoyed.

It was obvious from the start that Alpha Go was superior. I mean even before it first won. It does shit that no human can do, that is how it managed an amazing comeback that any human would have fucked up.
What the fuck is this shit?
I am not a STEM.

Well I'm no expert, but they look like derivation rules for propositional logic.
[math]\varphi[/math] and [math}\psi[/math] stand for some propositions, I for "introduction", E for "elimination", the horizontal bar for the deduction associated to I or E and the funky symbols for logical connectives.
Just some rules for expressions you can use in proofs.
How come that this works?
it doesn't

For one, my shoe size is two digits
Secondly, you just multiply the shoe size by a number with 100 as a factor, so when you add 2012, the last two digits are 12. When you subtract your birth date from that, you get obviously get your age.
You should change this to 2016 btw cause this would only work 4 years ago.
>12
>60
>110
>2200
>3212
>1228
this predicts that my shoe size is 1 and my age is 28.
my actual shoe size is 12 and im 31.
proved you wrong
Is "Psychology = pseudo-science" just a meme? I used to think it was just about hand-holding and bad science experiments, but that's obviously changed a lot since the 1950's and with the advent of fMRIs, EEGs and the like. And its employment of statistics seem to be pretty strict.
What does /sci/ think? Is society just slow to catch up to scientific advances within the field, or is psychology still a pseudo-science?

>Is "Psychology = pseudo-science" just a meme
No.
The first person to mention psychology and the person who created the word psychology was a Croatian writer Marko Marulić who lived on the 15th/16th century.
>>7938247
This is exactly the sort of thing I'm talking about. This argument would work perfectly for Freud, who developed an entire theory with the id, ego and superego (and all the sexual stuff) with no scientific testing whatsoever - he based it solely on his experience with his patients.
But psychology doesn't do that anymore. The only field within psychology that even comes close is social psychology, and even that isn't as bad as what that picture depicts.

When bearings roll inside of a chamber, they also slide against each other, and against the roll surface.
There's a coefficient of "roll friction", but since the motion isn't pure rolling, how do you calculate friction?
Depends. You'd most likely have to use sphere moment of inertia. To calulcate the inertia of the ball bearings. Then go from there.

After you die and your brain has decayed, wouldn't eventually your brain reform due to quantum fluctuations and tunneling? Does this mean immortality?
No thats all bullshit. Dead is dead you hippie motherfucker.
is it theoretically possible? maybe
would is ever happen? no
Consider your body a wave packet and your thoughts constituent waves. If the packet is destroyed the constituent waves dissipate into nothingness. While there isn't a wavefunction for consciousness, probably, it's highly unlikely these waves will reform into another being.
how do I learn to design audio without becoming a fucking CS faggot?

If I'm rolling something on a bunch of ball bearings, do I need to overcome static friction before the thing starts rolling?
nope
>>7937672
ok thanks
>>7937643
you need static friction to stop the base of the ball to start rolling.
Are there more waves than electromagnetic and mechanical waves? The reason I ask is my girlfriend is crazy about crystals and whatnot and insists that crystals and humans transmit waves. Obviously any educated person knows crystals do in fact transmit small electromagnetic waves So I was wondering, is it possible that there are waves being transmitted on a spectrum we do not yet understand? Before the discovery of electromagnetic waves we did not know gamma rays, radio waves, infrared existed. So is it possible that my girlfriend is not bat shit crazy/stupid and that humans/crystals...

Don't worry op. My wife believes in essential oils holding magical powers and other voodoo girl blog mom science. They are just naturally stupid. Don't hold it against them.

Thanks, I guess the question is unanswerable but I was wondering if anybody knew anything more than just "no one knows"
So anyway, I'll be doing a biochemistry major when I start college next year. For my minor, I really want to do Japanese because I enjoy the language and culture, and I'm currently studying it on my own and would like to continue it into college. However, I feel it would have little use as a language compared to Spanish when it comes to medical school but my school doesn't offer spanish and I wouldn't take it even if they did. My alternative is a minor in computer science because that's also something I enjoy but for the medical field don't think...

Whoa there Charles Dickings I didn't come here to read your graduate thesis.
But anyway medschools don't even look at your major, let alone your minor.
Statistically speaking, you have no advantage with any group of majors or minors or anything. They. Don't. Care.
Whatever major gets you the closest to a 4.0 is the major you should choose. They only care about prereqs and GPA. It's that simple.
If you feel like a Women's Study major is easier, go for it.
Explain...

So..basically go for the easiest one? I'm still doing a biochem majior sice it'll help me keep god MCAT score and prereqs guranteed covered, so I guess go with the easiest minor? I want to do japanese but parents will not approve. How do I get parents to approve?
tl;dr: How do I get my parents to allow me to minor in japanese since they won't approve?
Is software engineer a meme degree ?
Yes.
>>7936640
On /sci/ anything that isn't a maths or physics degree is considered a meme degree.
>>7936658
Only by maths or physics majors. Do your part to make /sci/ great again. Post more threads relevant to other fields of science.
I've been looking at the 2016 primary results and I noticed a pattern. If the corporation counting the votes used an algorithm to skew totals, would it be obvious when looking at sets of data primary data?
When I divide Sanders votes by Hillary's I almost get ratios of 1/4, 1/3, 1/2, and this is on nearly all the results they did not tie. Whats strange is this doesn't work as well with the 2008 Hillary vs Obama primaries where the ratios are more random.
Trump typically leads with 1.5x as many votes as the guy in second place. His victories also...

Sanders is loosing because he has political bagage, not because of conspiracies.
I just assume that all elections are at least a little rigged. Sanders is obviously too leftist for the masses but Hillary isn't very popular either so idk what that leaves us with.
1. WHY does space expand?
2. Does space expand uniformly? Is new space created only between galaxies or is it also created where there's lots of matter already (like in our bodies for example)?
3. If space doesn't expand uniformly, why?
Those aren't stupid questions at all.
>>7935975
>Is new space created only between galaxies
It's not "new" space.
The same old space is expanding.
I don't know about the rest.
>>7936009
I was under the impression that galaxies and such are actually stationary and space is created between them, which gives the illusion that they are moving (which explains how galaxies can seem to move faster than the speed of light).
Is it possible to build a working computer entirely out of wood? If so, what sort of computations could be done on this computer in a reasonable amount of time? (e.g. Would it be able to beat a person at chess?)
When I was a kid, 50 years ago I used to go see my dad in work, he was an accounts clerk and had a mechanical calculator on his desk. I believe much larger mechanical calculators do exist.
Yes. It depends on your definition of reasonable amount of time.
You might be able to do something like the tinker toy computer. It wasn't really a computer and was just a big mechanical look up table.
Evaluating chess moves is probably something that could be done in parallel, so you might be able to make a huge purpose built machine to do this
But it would be very slow.
