a2+b2+2ab=2ab+n2
so a2+b2=n2 Life should consist in at least fifty percent pure waste of time, and the rest doing what you please.
At no point in the proof there is a nonhomogenoeous polynomial adding a length to an area, for instance. So Ceebs' argument can be written out in words involving areas.
I think that diagrammatic proof of Pythagoras' theorem may have originated in India? We have met the enemy, and he is us — Pogo
I'm still pondering the idea of an "imageless" maths that invokes images (the diagram above), or a graph--something visual at any rate that stands for...the invisible maths behind the image...
So it may be easy, but easy is good (for me) if it helps me concentrate on the underlying aspect, in this case:
When one advances enough, the pleasures of maths become non-visual ; Maths after all is the art of abstract symbol manipulation.
(Thing is, I have pondered this and I am wondering whether maths' claim to be somehow bigger than the universe (maths gives us "the universe" + 1)--I mean the idea that maths "encompasses" the universe as compared to the universe being "bigger than maths"--Heh, I'll have to try and explain this again later, but I mean something like: "What does it mean that we can't beyond a certain exponential--I was thinking about mathematical models of the universe--there is the "empty box" model, we are in it and the sides are an endless distance away. Then there is the "closed form" model, balls, saddles, but always (inevitably) seen from "outside"...heh...I'll post this just to remind myself that I had a thought in there somewhere. Don't fight forces, use them R. Buckminster Fuller.
Notice that before the development of symbolic algebra in the middle ages, elgebra had always a geometric interpretation. Squares were the areas of squares. Linear quantities were the lengths of segments. Cubes were the volumes of actual cubes. Inhomogeneous polynomials (mixing quantities of different degree) didn't often occur.
Mathematics has always been visual, touchy-feely, intuitive, until the formalization in the 19th century. We have met the enemy, and he is us — Pogo
But this one should be really easy. We had to find this out on ourselves, I don't know, maybe as sixth graders.

Do you know that Set Theory proves that there is no Universe?

Saddles are a representation of open ever-expanding hyperbolic universes. *Traitor*, n. A benighted individual who perceives an illusory distinction between serving his nation and abetting the criminals who govern it.
