Yes, here's to 2008! And my New Year's Resolution is to clean up my act. That is, to act more professionally and not deliberately scare people off. Okay, except maybe at the chess club down at the mall.
LOL! Well, good luck. I never have New Year's resolutions. I just have long wish lists.
Congratulations on being phuddded! Have a good NYE.By the way, there's a current slashdot article about one of your colleagues up now.Philip
12 29 07Congrats!!! Nice smile!
That's a radiant smile! In your PhD research did you discover the secret of time-travel? You look about 20.
Philip, I'm not sure what slashdot article you mean. There are so many. And Nigel, close up you can see some lines, I assure you!
http://science.slashdot.org/science/07/12/29/1540233.shtml looks interesting!
It links to http://www.abc.net.au/science/articles/2007/12/21/2124258.htm?site=science&topic=latest which reports that Dr David Wiltshire's research on dark energy was recently published in Physical Review Letters, which is a step in the right direction for science.
Yeah, that's right, Nigel. Perhaps I should join Carl in becoming more professional - I forgot to mention the publication in PRL, which no respectable no-DE partisan would ever do!
Kea, an X-mas gift perhaps to add to your paper on Fourier transforms: Off Diagonal Geometric Phases, Nicola Manini, Fabio Pistolesi. (Look for a circulant 3x3 matrix inside.)I was unaware of Berry phase and reinvented it for myself in density matrices. Quantum states take an arbitrary phase (that they call a gauge choice), and their phases change as time goes on. What Berry did was to figure out how to calculate phase changes that are due only to the geometry; that is, while ignoring the gauge phase choice and the dynamical phase changes.This is a lot simpler in qubit density matrices (where I work) cause there is no dynamical phase and the arbitrary phase gauge is cancelled when you get out of spinors and into density matrices. So it was a LOT easier for me to discover this than it was for the originaters.However, this all gets back to improving the professionalism of our work. Part of that is tying our stuff into the existing physics literature, and this is a good strong knot.
Hi Kea and Carl,The Berry [ geometric] phase in QM and EE is related to the Hannay angle in ME.This is also related to polarization with linear, circular and elliptical variants of the helix.See the illustration in the section Basics: plane waves.
I see they call it the Pancharatnam-Berry phase. I'm sure I've seen this many times before, but I find it hard to be professional when nobody is going to publish my papers anyway.
Lovely photo! With that outfit you would be a hit at a Renaissance faire.
Hi Kea,congratulations, and a terrific outfit! Nice picture, post more of them! Remember, a blog with no pictures is like a newspaper with...well, no pictures. Lol.Cheers,T.

Desperate servient fools want to know!I want to make beautiful music with you.
Dear Chimpanzee, LOL and thanks. I am very tempted to delete your post, since its dreadfully embarrassing, but since it's your first post here I can only say Welcome. I spent a lot of time in my youth studying music, singing in choirs etc, but that was all some time ago now. I do miss going to the opera occasionally. And by the way, I'm not in the habit of wearing the UC academic dress, which is certainly based on medieval traditions, but taken seriously still today.
