This is pretty significant people. This should be like the number one sift. Essentially, this says that a computer can determine fundamental equations of dynamics of very complex systems using network theory. So we can solve problems that were previously thought to be intractable, provided we have all the dependent and independent variables.
A) A computer observes the behavior and dynamics of a real system, and (B) collects data using motion tracking cameras and software. It then automatically searches for equations that describe a natural law relating these variables. (C) Without any prior knowledge about physics, kinematics, or geometry, this algorithm found conservation equations and invariant manifolds that describe the physical laws these systems obey. Pictured, are an actual double pendulum, collected data, and resulting energy conservation law found.

choggieI'll promote this next go-round MH....
XaxUhhhhhhhhhhhhhhhhhhhhhhhhhhhh... what?
MycroftHomlzThey wrote a program that not only solves the dynamic equations for complex systems, it autonomously determines the equations.
So previously indescribable phenomenona can be described by simply inputting the data into the computer. Easy-peazey-lemon-squeezey baby...
gwiz665So, uhm, *quality!
siftbotBoosting this quality contribution up in the Hot Listing - declared quality by gwiz665.
Angua1says...The implications here are enormous, as suggested by Radio Lab here: http://www.wnyc.org/shows/radiolab/episodes/2010/04/16/segments/149570. Radio Lab suggests we've reached the limits of human and scientific understanding and use this computer program as an example. The piece also talks about other researchers who have used the program to input biological data, I believe complex DNA and protein interactions (can't re-listen to it right now to confirm for you). The point is that the computer spit out a whole lot of interesting equations ... which were previously unknown to science. No paper can be published on these equations because the way we generated the equations don't fit conventional scientific methods. Fascinating stuff.
SighThis is the first time this has been sifted? This computer has been around for quite some time now.

Seems like we have reached the first step on the way to the singularity. Go Science!
I can't wait for the time when we fragile meatbags are replaced by silicone and steel.

Ahh... their publication in Science was last year?
deathcow*doublepromote this is awesome, point it at a bucket of swirling water next and have it model ink droplet distribution
siftbotDouble-Promoting this video back to the front page; last published Wednesday, April 28th, 2010 8:07pm PDT - doublepromote requested by deathcow.

rottenseedthis makes me want to cry.
MycroftHomlz^only because you are weak.
PaybackI would like to be the first to welcome our new problem solving computer overlords, but from what you say, they probably already know.
w1ndexNeat. Glad I am starting back to school soon.
LarsaruS>> ^therealblankman:
nerds
Captain Obvious makes obvious observations
choggie↑↑ HAH! Nerd Alert!! ↑↑

Only because this is insanely awesome and I am envious of those with the skills to design such a wonderful computer.
shponglefansays...When it starts making machines, we're screwed.
daxgazwell, duh! I knew this all along, but i wanted to see if they knew it too so i didn't tell them about all the science and stuff i did to figure it out.
gharki enjoyed the pope song more
Avokineoksays...*promote
Very very interesting. I don't really care how long this information has been available, I didn't know it yet. Thanks for the great sift!
siftbotInvocations (promote) cannot be called by Avokineok because Avokineok is not privileged - sorry.
harryNext up: a computer than can actually play Crysis.
ThrobbinI have one...that's been out for awhile now too. Playing in 64-bit mode is epic. Multiplayer sucks though.>> ^harry:

When it starts hiring Mexican machines to do its yard work we're screwed too...

vaporlockWon't be long before they (the machines) figure out that we are a problem that needs "solving".
lampishthingDid it decide that the two thetas and omegas were worth playing with itself or did the humans tell it that?
xxovercastxx*geek *engineering
Does this mean I can have my flying car now?
