Have you ever wanted to blow something up? Or maybe you always dreamt of operating an atomic power plant? Do you have a will to develop your own CPU? The Powder Toy lets you to do all of these, and even more!
Pretty cool game/tool with lots of neat physics and chemistry involved.

Can I predict the stocks with fractals.
Of course! I mean, your predictions won't be accurate, but you can do it.

Did you ever creep out normies with your math skills, /sci/?
Everytime I code and people look at my screen like I was hacking the matrix.

I know you do that on purpose to feel superior.
But you can't even talk to a chick.

Yes. We're waiting for the next KBO in 2019. Shame i won't be Eris.
Triton is a much more important KBO
So important that Neptune stole it for himself

How long would a manmade object like a solar sail would take to reach near lightspeed levels ? Is it possible to send a probe and back to the nearest star within our lifetime ?

I have a '5 page long' essay on the question "How can renewable energy and energy efficiency help Scotland meet its emission reduction targets?" Due in six days. What the fuck do I do?
I didn't sign up to Civil Engineering for this
write DUDE GLOBAL WARMING LMAO
Fuck off and get good
Sincerely,
Your Professor
>>8013572
Investigate whether renewable energy sources in general have lower emissions than non-renewable energy sources
Investigate whether being energy efficient results in lower emissions than not being energy efficient
Setup definitions to this end
Be really pedantic and investigate lots of edge cases
Maybe derive propositional logic and set theory as filler
If you knew all the laws of the universe and how matter works on the most fundamental level, and had knowledge about the exact conditions at the start of the universe, could you "calculate" the future by simulating the universe from the start?
The problem of there not being enough storage for all the data points because the number of smallest elements needed to be simulated is as many as in the real universe, which means true simulation would be impossible. But you could work around that if you could acurately enough predict how a system of elements (say billions)...

>could you "calculate" the future by simulating the universe from the start?
No.
Even in a deterministic universe (and this ISN'T a deterministic universe), the three body problem would prevent you from doing this.

>the three body problem would prevent you from doing this
this meme needs to die
it has a well defined solution
The answer is still no, but because OP would need a machine (a simulator or whatever you want to call it) bigger than the universe itself to simulate everything in the universe.

In short, all signs point to aliens.

There is literally nothing in this post that's correct.

Jesus Opie, there are already at least two threads about this.

Is time relative?
No. Everyone in the universe has the same sense of time, and no one has ever had an issue with clocks ever, especially when moving at high speeds. No arguments here, off with you.

Why all the sarcasm? There could be a good discussion about all this stuff. Or did I post this in the wrong board?
>>8013408
Yes this is a well known fact.

If scientists can't even predict the probability when a recession will happen, could they be grossly underestimating the probability of intelligent Extra terrestrial life forms existing in our galaxy that have already achieved FTL travel?

This doesn't follow from your link in two ways:
>1.) They clearly had predicted it, and predicted such movements were incredibly unlikely to happen.
>2.) It isn't talking about the the 2008 crash but a particular model a hedge fund was using.
That said, I doubt they developed their models to include the wider malaise...
