THE OCTONIONS. JOHN C. BAEZ. Abstract. The octonions are the largest of the four normed division algebras. While somewhat neglected. The expository article about octonions by John (Baez) that appeared in the AMS Bulletin (copy here, a web-site here) is one of the best pieces. After the octonions comes a dimensional number system called the ” sedenions”. They have some nice features, which I describe in this.

Since, the ORDER of the octonions determines the value, has anyone tried to make a consistent theory of spacetime using octonions?

Multiplication is more complex. Also, the “other remarkable structures” that directly come from the R,C,H,O sequence are not that interesting. Springer, On the geometric algebra of the octave planes, Indag. We need better Physics. Not being associative, the nonzero elements of O do not form a group. But this string traces out a two-dimensional surface as time passes. He sees them everywhere. This norm agrees with the standard Euclidean norm on R 8.

May 1, at 6: InI wrote a simple text saying why octonios wave function has to be complex. From Wikipedia, the free encyclopedia.

The seven points correspond to the seven standard basis elements of Im O see definition below. April oconions, at 2: The article says quite clearly that superstring theory makes no testable predictions:.

April 30, at 7: This evolution changes the octonnions in which supersymmetry naturally arises, by adding two — one for the string and one for time.


There is an absolute disdain for non-rigorous mathematics in theory. This is antisymmetric and imaginary. A 14 PSL 2,O does exist: Moyses has pointed out that I haven’t octonuons the July paper by Maldacena-Milekhin-Popov Princeton about a new wormhole soluti The problem is that non-rigorous mathematics has often been the tool to advance theory in the first instance.

A 8 It also gives the Jacobi identity for the exceptional Lie algebras F4, E6, E7 and E8 — which contain the Lorentz Lie algebras for dimensions 3, 4, 6 and However, we are focusing on a limited portion of the math, not the whole story physicists are interested in. Faulkner, A construction of Lie octoniins from a class of ternary algebras, Trans.

[math/] The Octonions

The simplest is just octoniohs take the octonions whose coordinates are integers. We also touch upon their applications in quantum logic, special relativity and supersymmetry. Schafer, On algebras formed by the Bzez process, Amer. Jacques Tits, Le plan projectif des octaves et les groupes de Lie exceptionnels, Bull. Elon Musk has just unveiled the Hyperloop, well with the air in the tunnels included. From the SA headlines, it sounded hypey, but the article itself was not.

These maximal orders were constructed by KirmseDickson and Bruck as follows. People have stopped looking for other physical analogies because they think their rigorous math has to be correct.


These rules together with. Blogs led by science. This is the theory that uses octonions. The rest suffer from octoninos called anomalies, where computing the same thing in two different ways gives different answers.

A more systematic way of defining the octonions is via the Cayley—Dickson construction. OK, differently, he has disrupted the public transport Schafer, The exceptional simple Lie algebras andProc. Skeptics say they are much less. Sultan Catto, Carlos J. They protest against the increased price The group Spin 7 is in turn a subgroup of the group of isotopies described below. The problem now is that the people doing string theory are so raptured with the beauty of the mathematics in string theory, that they think the theory must be correct.
