The wikipedia page should give a good enough 'short summary', don't you think?

>The Lagrangian is a way to represent a physical system. Every fucking thing in the universe can be written as a lagrangian.
Well that assumption is a meta statement. It only works as long as it works.

>Matrix sequels

I like how Physics is totally apart from Biology, Physics and Chemistry barely intersect and Economics doesn't really use any Math.

For starters, you failed at collecting the y^2-terms, try again.
Aside form this, if x and y are independend variables and you imaine them spanning a 2-dimensional space, then your total (complex) space is four dimensional and eighter these equations are viewed as defining a 2-dimensional plane, or they are not viewed 4-dimensional but just as two independend restrictions to x and y in which case there might be a solution (be there is no real solution in your case)

Btw. I also find this to be neat:

I could post videos like this

but I'd rather discuss things than posting or watching videos. Also, I like your video, but Feynman has such a douchbag vibe and history/anecdotes, I don't enjoy the videos too much :/

I came up with a cute little algorithm.

But something's buggy, it claims

a=356811923176489970264571492362373784095686656

b=2596148429267413814265248164610048

and

c=618970019642690137449562112

is a solution.

For things in time and space (spacetime) you have coordinates:

>I'm at (t,x,y,z)=(0,0,0,0).
>in 99 minutes I go to the toilet
>I will be at (t,x,y,z)=(99,13,5,0)
(if x=13 and y=5 describes where my toilet is)

You store information as configuration of objects in space. Let it be a symbol witten down (color in a certain configuration on a piece of paper). photo consisting colored particles, a compute consisting of a flash drive in a certain configuration or the brain, with neurons etc. in a certain configuration.

gimme an example?
What I know and which is fascinating, is that people of different countries actually observe different colors. If you have 5 words for purple and see two skirts of color purple#1 and later purple#2, then you will remember two different skirts, while someone else will not remember a difference (russians have many words for colors btw.)

Chase after hot ones and be awesome and be completely sideswiped when the girl of your dreams was right in front of you all along.
