Comment: I can program, not in the terms of a job interview (Score 1) 723

I am not a programmer. But I have potgraduate education which included enough programming information.

I do not have programmin in my fingertips, but when given a programming problems I can pick i up, look at manuals (and increasingly the interenet) and work out a program as required.

As long as companies don't understand that interviewing is not really assesing the qualities of the prospective employees they will continue to experience "shortages".

Comment: Churchill (Score 1) 118

Democracy is a failed political model.

I think Churchill said it better: "Democracy is the worst form of government, except for all the others which have been tried.". I agree that democracy - at least in the form we have it in the west - is seriously broken. However I have not seen a better model than democracy - every other form of government gives worse results on average. So we are stuck with democracy until someone has a better idea.

Wow you're a dumbass. Obama added almost 6 trillion to the national debt in four years.

You do realize that this does not contradict the OP? Obama could have done as you say and STILL have the lowest spending record of the last 60 years (I'm assuming that is adjusted for inflation otherwise I think it unlikely). All it needs to happen is a huge drop in income from taxes which, with the current economy I would guess is a definite possibility.

Disclaimer: not American, no clue what or what not Obama has done and I don't really care anyway.

My apologies - you are correct and I meant to get the scales the other way around. Although the scale is ~82 GeV since it is a W, not a Z ;-). Since I have not had a chance to properly read the paper yet (which also does not help! it's on my list for next week) what was the reason for the large range of scales? Anyway its great to finally see you lattice guys really start to make in-roads on some interesting QCD calculations - it will be nice to see some QCD predictions which depend on the fundamental physics which we can then go an experimentally check rather than predictions based on simplifications and assumptions.

Note that the states are often referred to as K1 and K2.

Not quite, K1 and K2 are different: the real, physical states are KL and KS. The K1 and K2 states are the pure CP eigenstates. If CP were a perfect symmetry of nature then you would be correct and the physical long lived state would be the same as the CP=-1 state (which can be either the K1 or K2 state depending on your convention) and the short lived state would be pure CP=+1. However because CP is not a perfect symmetry the long-lived kaon state, KL = N*(K1 + epsilon*K2) and KS=N*(K2+epsilon*K1) where N is a normalization factor (=1/sqrt(1+|epsilon|^2)) [NOTE: K1 and K2 can be swapped depending on your convention]. So the KL and KS states are NOT the same as the K1 and K2 states because of CP violation. "Weak Interactions" by Cummins and Bucksbaum has a full rendition of the physics starting without the assumption of CPT conservation (which gives two different mixing constants for KL and KS). It's a beautiful example of QM mixing.

Not that I want to make you more depressed but the above post was at a level somewhat below what I'd expect final year undergraduates will understand - at least the ones who have taken an undergrad particle course. The only exception being the A_0 and A_2 amplitudes which is specialized kaon physics. If you are studying matter/antimatter interactions then you ought to know this stuff. There is a good undergrad book by Griffiths, "Introduction to Elementary Particles", which has a section on CP violation including the the B meson sector. I'd also happily share by lecture slides on this but my university has not yet implemented public access to course material.
