Marcus du Sautoy: Symmetry, reality's riddle
wie Sie tun, machen, Film, Beispiel
http://www.ted.com The world turns on symmetry -- from the spin of subatomic particles to the dizzying beauty of an arabesque. But there's more to it than meets the eye. Here, Oxford mathematician Marcus du Sautoy offers a glimpse of the invisible numbers that marry all symmetrical objects. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the "Sixth Sense" wearable tech, and "Lost" producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts. Closed captions and translated subtitles in a variety of languages are now available on TED.com, at http://www.ted.com/translate.

The sixth symmetry of the star fish reminds me how mapping a figure to itself is a fundamental mathematical structure of reality, made use by Turing trying to solve the 'halting problem' in his computing machine, by 'self-reference' in which the input and output terminals were plugged in his original. computing machine.

Im a speedcuber. My name would have been on the object lol! I was yelling 42 Quintilion throughout the whole vid :(

She is the astronomer Andrea Ghez. wow

For every boson, there is an anti-boson. For comments, for every bozo, there is an antibozo. Nature is full of symmetry whether subatomic or morphological. Fractals occur in nature, and to me, a mathematical pharmacist, appear to be an infinitely symmetrical design.

That puzzle was so mean. :)

Symmetry is key.

So the winner sat down initially on the <= 20 criteria, but then stood up and said she had a 21 digit number. Suspicious!
-
WOW, there's a whole lot of ignorance in this comment section. I thought it was a great talk.
-
when will teachers understand that the important thing is not what they say but what the people in the audience understand. This would make them speak slower and more clearly. Talking too fast is a waste of time if nobody can follow the explanations.
-
cool lecture :)
-
Indeed it is very dumbed down. Although, if it wasn't for him and me reading his books when I was 17, I may not have been revising for my fields and galois exam right now. Sorry for replying to such an old comment!
-
wasn't winning the riddle a rather easy thing. Yo just had to be closest and he was saying those with less than something sit down and the like. You just had to keep standing till the last and you will automatically win.

The swastika is symmetric. You obviously only know one kind of symmetry. Which demonstrates that you lack the basic knowledge to participate in any kind of conversation about the mathematical concept of symmetry. Please for your own sake, read up, and come back when you're ready.

I didn't learn anything from your "lesson." Stop this foolishness; you won't hear from me again.
-
do you realize how many dummies there are like you out there in the asymmetrical world that need tutoring? but did ya learn anything jimmy from me brief lesson?

1 year and then a response...

ROFL science has become a religion, I wonder what Marcus S ideas are about 'space' 'time' 'motion' and 'god'? because religion somebody once told me ... has tried to define TIME since the beginning of TIME i.e. religion is TIME "in the beginning" and "amen" is my evidence? Who is in charge of the TIME clock right now? Pope Gregorian and company? sheeple are oblivious to the obvious

ROFL so you folks think you understand ASYMMETRY? I can take the ASYMMETRIC swastika and rotate it four times, i.e. every 90 degrees, this is known as 4-fold rotational symmetry. an equilateral triangle would have 3-fold rotational symmetry. (120 degrees x 3 = 360) and a circle has indeed does have PERFECT SYMMETRY. i.e. it does not have 3-fold or 4-fold rotation, it has infinite-fold rotation. Get it? too many PhDUHs are being handed out to simpletons who have forgotten the basics... IMHO

ROFL and by jOve who are you? How many Nobel prizes and awards have focused on ASYMMETRY? jOve do a search on the internet: "at 37 The Importance of Asymmetry" Let me ask you a simple question that gets to the heART of the matter. Which do the scholars reckon is more important to a machine/tool building civilization like us, the ASYMMETRICAL 'hand-axe' or the SYMMETRICAL 'wheel'? also why did 'THEY' (wise elders/script writers) put the ASYMMETRICAL swastika over the heART of the Buddha?

contempt for du Sautoy's broadcasting technique.
