Still Down South V

That was a very enjoyable late summer trip, with perfect weather. Thanks to Kerie and Tasman (the dog). One cannot have such beautiful valleys to oneself in England. Nonetheless, tomorrow I phone Australia, yet again, in an attempt to find out how my visa application is progressing. It appears to be no longer possible to speak to Wellington.

Ah ha! You're not going to find such inspiring scenery here in England. Hope you make the most of the New Zealand summer while you remain there. Is it warm enough to sleep in the open in sleeping bags, or do you take tents with you?

We should enjoy the scenery in this brief time. Someday we will all miss the South Pacific, the most beautiful corner of Earth.

Hi Nigel and Louise. Nigel, it has been warm enough to 'sleep out', although we slept in a tent. It is very altitude and weather dependent. I am standing here at only about 900 m above sea level.

Okay, I've got the generation calculating software running. This means complete non commutative primitive idempotents for the three generations. I've been computing what happens when you cement an I, J, K, R, G, and B between these. This means 9x6 = 54 calculations to do the full set. Each calculation is the product of three 3x3 matrices, each multiplication treated as non commutative. This is a lot of work, it's good to get it in software.

Good news is that I, J, and K type color mixing does produce 1-circ type generation coupling while R, G, and B type color mixing make 2-circ type generation. Bad news is that I don't get the MNS matrix values.

I, J, and K each give 1-circ coupling in I form. Relative couplings are 5/9, 5/18, and 5/18, respectively.

R, G, and B each give 2-circ coupling in G + B form. The G and B entries have couplings (again in squared magnitude) of
(5/9)(2 +- sqrt(3))/6,
where one sign appears in G, the other in B.

Uh, I should mention that I've put the (1,1,1) generation (which is presumably the heaviest generation) in the "B" position.

I forgot to add that these calculations don't include properly symmetrized incoming and outgoing states. It's possible that including these will give the MNS matrix.

By the way, the CKM matrix is not as symmetric because not all the symmetrization is legal.

Whoa! If this is what you see normally, why in the hell would you want to leave anyway?

LOL, Mahndisa. Yes, there are countless valleys like this in the South Island, which is why one can easily find one for oneself, since only a few people bother to walk much.

So you now have a camera? Please post pictures of Kerie & Tasman.

Do you gaze at the stars at night? The Southern Milky Way is pretty awesome.

You mean a tent & water bottles are inside the Mac Pac?? What kind of food do you pack?

Do you carry bathroom tissue for potty-time? For the latter, do you just go in the bushes & find a rock (to act as a toilet seat)? This is my standard modus operanda.
