How is your summer going?
Its me your somewhat banished friend with an interest in quaternions. I have been spending the day reading Jasper Jolly's book, Manual of Quaternions from 1905, and started wondering how you were doing. The funny thing that I noticed is that after I resolved to not edit the article on Classical Hamiltonian Quaternions any more, it suddenly stopped being edited at all.

The first 30 pages of Jolly's book are really easy, but he really changes up on the definitions that Hamilton offered us on the subject of quarternions. Particularly missed is the approach of taking a quaternion as being the quotient of two vectors, but since Jolly has proposed to write a short book, he claims there is a need for his simplified definitions.

The first pages seem easy, but there is an interesting treatment of dynamics in his book, that I have yet to manage to fathom. This seems to me unfortunate since I am supposed to be a mechanical engineer.

But well hope all is well with you, and wanted to offer some encouragement if you were thinking about doing some more work on quaternions! user:hobojaks —Preceding unsigned comment added by 76.191.171.210 (talk) 21:37, 29 May 2009 (UTC)
 * Hi there, thanks for checking. The summer is going great, lots of work to do. Just sent a paper for review, that looks at octooctonions (octonions with octonion coefficients) for potential use in physics. Then I'm finalizing another paper with a friend, on some "doubly nilpotent" space (whatever that may mean; hopefully we've made a solid case for the system). Finally, the coolest conference on the planet is coming up, with some of the best mathematicians and physicists that usually don't associate. There, I'm happy and glad for the opportunity to give a brief talk on what must almost certainly be the hottest topic these days in physics: Nonassociative quantum theory! ... At least, that's what the two of us and then maybe a few others think ... maybe ... :) ... Well - gotta make your case first, do a few years of homework, and then advertise for interest, right? -- In other words: I'm reeeeally busy. But it's nothing a few lazy weekends at the pool can't fix in July. Cheers, Jens Koeplinger (talk) 00:21, 30 May 2009 (UTC)
 * It's July now, and I surely am enjoying the pool and a few vacation days - but I must confess that I'm bailing out of doing involved updates in Wikipedia any time soon (including Classical Hamiltonian quaternions). Sorry. I know I'm breaking a promise. Thanks, Jens Koeplinger (talk) 13:06, 20 July 2009 (UTC)

Musean hypernumber
Could you please explain to me what the 10th level of Musean hypernumbers is all about? Thanks. Protactinium-231 (talk) 14:11, 31 October 2009 (UTC)
 * Sorry, I can't. I can make some sense out of "levels" 1 through 6 (though I wouldn't put them into an ascending order of sorts), but beyond that I don't understand it ... The references are pointing to key papers. Thanks, Jens Koeplinger (talk) 21:13, 1 November 2009 (UTC)
 * It seems that the house-of-horus website has content about levels 1 through 9. However, it's not reliable as a source. 23191Pa (chat me!) 13:36, 6 November 2009 (UTC)
