Slippery Sunday

This is it, folks! Topos theory (a la Isham at least) has made it to the cover of New Scientist. Thanks to The Cafe for the news. Our mathematician friends will doubtless be amused by the prospect of overhearing debates about intuitionism on the bus.

Meanwhile, Christchurch hosts the Armageddon Expo this weekend. People are certainly being entertained. Don’t forget to register for GRG18 in July! The conference website now has a preliminary timetable and participant list.

    What a lovely issue. ❤

    Just out of curiosity, kneemo: when you spoke to Smolin just now, did you by any chance mention ongoing discussions on the blogosphere?

    Kea, I finally got “ticked off” at blogger for not allowing me to blog and am moving my blogging to at wordpress.

    Meanwhile, I should mention that I found some more solutions to the idempotency equations that involve the permutations of three elements. The cool thing about this is that it gives some hints on the mass interaction. The left and right handed pairs share a conserved value. I’ll update dmfound later tonight.

    Also, you might enjoy the NZ character in the new movie Grindhouse.

    A typical problem with blogger is the mess it made of the links in my comment.

    Dear Kea,

    I worked few years ago with the idea of dynamical logic and the little I possibly might have learned I got from papers of Isham et al.

    The idea of local and dynamically determined logic looked to me rather attractive. Truth values as sections of bundle. Moral dilemmas resulting when sections fail to be global! Mobius band would give basic example of a situation where truth becomes false when you travel around the world and return back to home;-).


    P.S. I added to my blog a detailed calculation of gravitomagnetic field in TGD framework. The field is dipole field only at equator and near Poles large effects are predicted. Angular momentum quantization results automatically in accordance with quantum classical correspondence.

    No, I didn’t get around to mentioning blogging. I just provided info on the matrix representation of the horizon and was trying to clear up the question of the value of j and the replacement for SU(2).

    Carl, I’m not sure why you are having problems with blogger, but your new blog looks nice! Matti, Q-Topos Theory is my approach. Isham has some nice results, but he is a long way from appreciating Carl’s derivation of particle masses.

    Kea, good reminder. I was going to register this week, but had to finish some papers. You should see me on the registered list by end of this week.
