Marcus du Sautoy: Symmetry, reality's riddle

sorry can "any one" tell me how she did the math for it,,or how any way?,,coz I'm not really that good to understand this talk "lingual".
just need a simple hint or a special time in this talk to focus on.
thanx.

I gave the lecturer a standing ovation. :)

That rolex ad at the end was kinda neat, lol.

In maths there can be any number of dimensions you dream up. Search for "Alan and Marcus Go Forth and Multiply". In physics there are possibly 11 'real' dimensions. Search for "BBC Horizon Parallel Universes".

Wow. people study symmetry?! i didn't realise it could be read this deeply. O_o ... so knowing all this.. what do we do with it? =/

You don't have to necessarily need to have a practical use for something. It's the joy in studying Mathematics that's the reason for even concerning yourself with it. Like Art, in my opinion there is no practical use for it but people take joy in viewing and expressing themselves within it.

Fair call. Art is different though... that's a creative thing, to express your inner feelings/thoughts/ideas etc and comes in many different forms. I guess symmetry is also a sense of art then isn't it? we do find symmetrical things more likable.

You couldn't begin to imagine just how far mathmatics take things like this.
There are some very obvious applications, such as theories about universal order, architectural development, and even the biology of life. Everything that exists has symmetry, and understanding it will help you understand everything.
But again, it can go even deeper than that. The best way to say it, I guess, is "if you take the red pill, you stay in wonderland, and I will show you just how deep the rabbit hole goes."

ahhh thanks for shedding light on this man. =]

OMFG he writes math liek i do, cept neater.
