There is a canyon that Gokei Okayama Prefecture Soja, Japan.
Here has been discussed in the net and in the ruins of the megalithic city rather than a canyon.
For if you look at the photos, but there are traces of human processed precisely the rock in rocky mountain.
People have a chance to come to play in Okayama, please try to challenge the mystery of Gokei.

Bullshit that looks like natural rock cleavage to me.
Have they found any rock chips or fire pits, things that much better indicators of human activity than shapes in rocks?
Otherwise,

There might be dead people, too scarey

All I see here is freshly exposed rock from when parts of it naturally breaks away due to weathering.
And complex pattern? Doesn't everything in nature has a complex pattern.

Wow it looks so small on the picture!

Then it wouldn't be in an equatorial desert, where solar power is actually practical.

Can someone help me understand what exactly is going on during a DMT trip? It is unlike any other psychedelic trip. I prefer your /sci/ence over some stupid Joe Rogan crap.

Thanks for the article, but allow me to rephrase. Can someone help me understand from a neurological and psychological perspective how a DMT trip affects a human? In terms of affects on the psyche. Also, it'd be wonderful to hear from /sci/entists who have taken the molecule and their thoughts on the subject.

Russian Physicists Launch Campaign to Rebuild Tesla's Wardenclyffe Tower and Power the World
“Tesla was right and we are ready to prove it!” So say the two Russian physicists who have just launched an Indiegogo campaign to rebuild Nikola Tesla’s Wardenclyffe Tower in Fall, 2014. Tesla believed that the tower could transmit power wirelessly but this was never definitively proven in his lifetime. If he was right, and after extensive study the team are convinced he was, the project could provide an efficient, worldwide energy transmission system that would distribute...

Probably.

It's basic physics that it will work, it's just pointlessly inefficient due to the inverse square law. To say nothing of how people would react to the idea of you pumping out gigawatts of radio waces everywhere when they already get buttmad about cellphones , where you'd find the spectrum etc.
hey guise can you help me with my homework i heard you were smart

Z(x,y)/C(x,y) + i/(Z(x,y)^(-3)*C(x,y)) = 2*Z^(x,y) - i/(Z(x,y)-3*C(x,y))
Integrate dx over 0,Tau and integrate dy over 0,Tau.
You will then be able to find any prime number. Discuss.

Based on Einstein's theory of Relativity, Riemann-Zeta is just a mathematician's approach to approaching the theory of relativity from pi -- a symbol that is broken because it is split in half; the true symbol for this approach is Tau, and the s in the Zeta function is for space-time itself.

are there any exercises or tips on improving your memory?
I have a pretty good memory, but I was wondering if it was possible to improve it.
> I was wondering if it was possible to improve it.
Good to know pal. Now fuck off.
>>6589951
Just like with muscles: use it.
>>6589951
People who win memorizing competitions aren't special, they just train really hard.
If you want to improve your memory then you just need to practice.
How important does /sci/ think doing well in high-school is in the 'grand scheme' of things, in a career/success sense?
I've always wondered, with the alternate pathways into University and 'higher grade' careers becoming more viable has doing well in high-school become less of an importance?
Or do you still think that how well you do in high-school and what ranking you get determines your University entry and the rest of your career life?
I've always heard tales of people failing in high-school and yet still becoming successful...

It's only important to get into the college/university you wish to get in. Everything else is compensative.
Basically, you need to know what degree of succes the University you wish to get in requires of you. Once you get, on most universities you basically start from zero so your previous knowledge doesn't matter.
I went to a language oriented high school and had a TON of luck to get into the top electrical engineering college at my country, and after I got in, I worked my ass off, did pretty good,...

4chan massively underrates education. Even /biz/ is full of retards who don't know anything about getting careers.
I'm an engineering major at a university that is ranked between 150 and 200. But because I got very good school and uni grades, I get interviews with investment banks in london for front office roles, various other financial companies including blackrock, Shell, IBM software engineering etc. I went to an open day for a strategy consultancy stuffed with LSE/Oxbridge graduates.
I'm not especially smart. my CV is nothing special.

unless there are entry exams it does.

Why are people so stupid, /sci/?
>This "problem" reminds me of a rant with my math teacher, back in school, where she just wouldn't agree that a coin could land on the edge. But this is not the point. You can't apply calculations to a chaotic system and expect predictable results.
What the fuck.
>>6586390
fuck, I was about to post that exact comment.
>>6586390
Is there a single part of this comment that isn't completely wrong? Even the coin falling on the edge thing should actually be impossible unless you basically threw the coin so it had no rotation.
Nuclear waste is radioactive, so why isn't it viable as an energy source?
I mean, its literally emitting energy, right? Thats the problem?
Is there really not a way of, at the very least, passively absorbing this? Even better.. can we not accelerate this release?
Thanks for your time.

So... why are we burying viable breeder fuel in the desert?
>>6590006
Because the only thing politicians know about nuclear power, is that uranium comes in, and useless radioactive stuff comes out, with occasional meltdowns
How high can I increase my IQ this summer? picrelated
By learning calculus.

20-30 points, doing iq tests.
searching for proven studying improvements.
meditation, sport and frequent breaks are proven to improve kognitive skills. anything else? going for a bootcamp style study
Either white noise or ambient music.
>>6591026
proven?
>>6591030
Statistics are shaky, but if you are going to listen to music while studying, those have been proven to produce better results than other genres.
For questions that do not deserve their own threads. There isnt one at the moment, so Im starting a new one.
Given that X,Y have joint density f(x,y)=2 for 0<y<x<1, find P(X-Y > z). What I did is sketch the area over which I should be integrating, and found the following bounds: z<x<1 and 0<y<x-z. Integrating 2dydx using these bounds results in (z-1)^2, while according to my book the answer should be 1/2 * (z-1)^2. What went wrong?
>>6573905
>joint density f(x,y)=2 for 0<y<x<1
The overall probability should stay 1 so you should renormalize it and there's your 1/2 factor
>>6573910
Nevermind, maybe I'm wrong, read
>0<y<x<1
as
>0<y<1,0<x<1
So I was going through past exam papers to revise for my maths next week and came across this.
Why isn't this \sqrt[4]{16}*cis(pi/4) for the first root?
I thought the way to find roots was \sqrt[n]{R}*cis((\alpha + 2kpi)/n).
Will regular reading broaden my vocabulary?
Is there any legitimacy in those "Brain Games" that claim to expand your mental abilities?
What about claims that regular exercise and certain foods -- rich in Vitamin D and Omega 3 -- will help grow my intelligence?
Is it all bullshit?
Am I forever doomed to be a dummy?
Or can I become a genius if only I put in the hard work?
The more you read and struggle with hard things the more you get used to it. If it is confusing and hard it is usually an indication that you're learning. Unless its so far above you that you don't get anything.
Regular reading is the ONLY thing that will broaden your vocabulary.
About a year ago I didn't know the first thing about science and wanted to become a musician. Now I'm studying ICT, earth sciences and remote sensing and I'm loving it. I just read popsci articles until they were beneath me and then started with the harder stuff.
>>6582235
No need to be a genius to learn bro. Just enjoy the process of learning without worrying about how quickly it grows your intelligence. Math and science aren't just cool because studying them makes you smarter
