Has anyone ever been able to create their own rocket which was able to launch something into orbit or beyond? I'm talking like trying to launch something to the moon.
If not, how feasible is this with no access to highly controlled materials (i.e. rocket fuel, guidance system, etc.)?
What would happen if you were caught (international laws against this)?
I figured that I would ask /sci/

When I was younger, we fooled around with model rockets and what not, never got more than that though. What are you launching? Just the rocket itself or did you want anykind of payload? Getting into orbit would be much easier than getting to the moon since you would have to figure out aim/traj. and probably need a way to make adjustments one you launch.
Probably feasible to do with off the shelf stuff though, as long as you get someone to fabricate your stuff (engineer).
No idea for legal issues, but will monitor out of interest.

After the Chernobyl accident somepeople feared that the molten fuel would explode with a force of 3 megaton, can someone explain how it would explode? I don't really understand

I think they were worried it would melt through the concrete foundations and come into contact with ground water making lots of hydrogen when it did, then that hydrogen would cause the explosion.
>>
>>6832381
You can`t get an atom bomb explosion (fission or thermonuclear3784) from a nuclear power plant. Explosions always come from steam pressure in sealed vessels, but three megatons sounds way too much.

Hey, I want to learn JAVA and PHP and need a decent beginners book that actually teaches the language, not just decent as a reference manual. And no, code academy and online tutorials won't work. I'm looking for a great paper page book. Any thoughts?

No, I took c and c++/c# a few years ago and understand the logic of programming, I just need a decent way and examples to learn the new ones. I learned SQL in about thirty minutes, but realize I need java and php to trigger the sql events. I just haven't find a book that satisfies both a comprehensive guide and the beginner to java and php qualifiers in the reviews. And yes, I googled, Amazon, and reddited for recommendations hags

I just read that there's a 50% chance that a GRB caused one of the major extinctions on Earth in the past 500 million years.
Question… how do you protect yourself from a GRB if it hits Earth? Would lead-lining in your basement protect you? How much lead do you need to stop GRB?

Guys, please help me. I'm about to crack the so far unsolved 18 last letters of the Zodiac killer's first letter.
This one:
>EBEORIETEMETHHPITI
I'm so close, you guys. It's all lining up. It's all coming together.
The only thing I need to know is why this
>http://www.acronymfinder.com/~/search/af.aspx?Acronym=VWYP&string=zip
brings me to San Francisco. Why "VWYP" brings me to San Francisco when entered in the location finder on acronymfinder.
I can't see anything related to those four letters, except (Los) Vaqueros Watershed being nearby (VW), which undoubtedly is going to tie it all together (murder at VW hinted in decryption).
But why this? Those were the only four letters I couldn't make sense of (I thought), but trying to find out if it's an acronym, I entered it in the location search, and it brought me exactly here, of all the places in the world.
Please help me understand, /sci/. I don't know where else to turn but here. I'm so close, /sci/.

It puts me in Tracy. West Valley Mall? I can't tell how this thing operates.

>>6770029
Yes, Tracy!
I just can't figure out what the relationship between VWYP and Tracy is. Or how this guy found these letters. Almost like he knew that fucking acronymfinder would lead me there. Simply typing it into Google Maps doesn't work.
I might have to find some numeric values, maybe there are plain and simple coordinates or an area code in there that acronymfinder.com can detect for some reason. On it.

There are more synapses in your brain alone than there are stars in our entire solar system.
I noticed that \int_0^1 \frac {dx}{(1+x^2)(1+x^k)} is always \frac{?}{4} \forall k \in \mathbb{R}. Why is that? Also, does it really happen for all k? Is there a proof?

It works similar to the puzzle with the sixes. But yet very different.
The goal is to complete the equations. All mathematical symbols can be used but you can not add numbers.
It works with the use of only these symbols: + - * / () ! abs() sqrt().
Can you solve it?

Why do so many great mathematicians just quit and do something stupid instead?
Grothendieke quit to write stupid political and environmental shit. Perelman quit to pick mushrooms. Galois quit to pick up chicks and get involved in politics... etc.
What inadequacies do geniuses see in math that makes them realize how trivial it is? Is it just tautologies?

>Galois quit to pick up chicks and get involved in politics
Galois didn't quit. He was challenged to a duel. It's speculated that the challenge was over a woman or that it was political but no one really knows for sure. What is known is that the night before his duel he stayed up and wrote down all of his mathematical research and ideas and entrusted it to his friend so that it wouldn't be lost forever in case he died (which he did).
Grothendieck thinks the world isn't ready and burned a bunch of his mathematical manuscripts. He also reached out to stop others from republishing his work.
Perelman left because a bunch of dudes tried to steal credit for his proof. So he thinks the mathematical community is a bunch of douchebags.
