The Higgs Story-Part 12: How the quarks and leptons acquire masses

In the previous post in this series, we saw how the Higgs mechanism gave rise to the masses of the weak interaction force particles W+, W–, and Z. We also saw how the process of spontaneous symmetry breaking that was part of that mechanism resulted in the Higgs field having a non-zero average value even in the vacuum, unlike every other field.

Glenda Jackson on Margaret Thatcher

Glenda Jackson was a wonderful actor, nominated four times within the space of six years for Best Actress Academy Awards and winning twice, in 1971 and 1974. She retired from acting and went into politics, and was elected as a Labour Party member of the British parliament in 1992 and has served continuously since then. She has been a strong voice for progressive causes and was a thorn in the side of the odious and unctuous Tony Blair, who was her party leader. She announced that she would retire from politics at the end of her current term, which would be 2015 unless elections are called earlier. [Read more…]

The Democrats and social security

So as expected, president Obama released his budget proposals with his offer to make cuts in Social Security (via the chained CPI) in return for some tax hikes. And as equally expected, some leading Republicans are now saying that it is the Democrats who are trying to balance the budget on the backs of seniors by cutting benefits in social services and that they are going to defend it (see here and here).

The need for anti-discrimination laws

Robert Ingersoll was a decade-long customer of Arlene’s Flowers & Gifts, a store in the town of Richland, WA who had often asked the proprietor Baronelle Stutzman to send flowers and other gifts to his partner Curt Freed. After the state passed a referendum last November legalizing same-sex marriage, Ingersoll and Freed decided to get married and Ingersoll naturally turned to Stutzman to provide flowers for his wedding. To his surprise, she refused saying that “I am sorry. I can’t do your wedding because of my relationship with Jesus Christ.” even though she had long known about his relationship. [Read more…]

Is ‘concierge care’ in your medical future?

A few years ago, my physician retired and I had to find a new one. One seemed good until I discovered that they had this tiered pricing scheme where the more you paid in the form of an annual subscription, the more services they offered. For example, with my previous physician, if I went for my annual check up, he would order the usual tests and then later his aide would call me and tell me what the results were (if they required no further action) or he himself would call me to tell discuss with me what I should do if the matter so warranted it.

The slow transformation of the conflict in Pakistan

In defense of its program of targeted killings in Pakistan, Afghanistan, and other parts of the world using drones and other bombing methods, the Obama administration has repeatedly claimed that its targets have been carefully vetted to make sure that they are high-value al Qaeda operatives and that their program is so precise that few civilians are affected.

Parallel news worlds

I had to eat alone at a restaurant on Monday and so took along something to read while waiting for my food. But as is the annoying custom these days, they had a TV on in a corner of the room, which can be a huge distraction. Fortunately the TV was far enough away that I could not hear it but I noticed that they seemed to be showing live coverage of a trial. I was puzzled because I follow the news fairly closely and could not recall reading about any major court case that would warrant gavel-to-gavel live coverage. [Read more…]

The Higgs Story-Part 11: The Higgs mechanism

We have finally reached the stage where we can explain the Higgs mechanism.

In part 3 of this series, I said that the complete set of elementary particles consisted of six quarks, six leptons, six ‘gauge bosons’ (particles that are the agents of the four fundamental forces), and the Higgs particle. In part 7, I said that there were patterns among the 18 non-Higgs particles, apart from some anomalies. (For previous posts in this series, click on the Higgs folder just below the blog post title.)
