In The Road to Reality (2004), Roger Penrose writes about a great analogy for symmetry breaking. Apparently, this analogy is rather common in the literature. (No, it’s not the thing about the pencil — this one involves an iron ball.) Once again, I find myself agreeing with Penrose about something; it is a great analogy.
Symmetry breaking (which can be explicit or spontaneous) is critical in many areas of physics. For instance, it’s instrumental in the Higgs mechanism that’s responsible for the mass of some particles.
The short post is for those interested in physics who (like I) have struggled to understand exactly what symmetry breaking is and why it matters.
It’s hard to express how weird the year number 2023 seems. (I can go on about it a little because it’s 
So. Here we are in 2023. Weird. Very weird. As I’ve said many times, I remember wondering whether the year 1984 would turn out to be anything like its infamous eponymous book. And the year 2001, also famous but more from the movie than the book, once seemed like the very distant future to me.
I’m generally not one for traditions or custom. I tend to see these as the enemies of thought and imagination. (Ralph Waldo Emerson: “A foolish consistency is the hobgoblin of little minds.”) I have always craved the new, the roads I haven’t yet traveled. Trying a new restaurant is more fun than revisiting an old haunt.

“Oh, the weather outside is frightful…” Bad enough that it’s three degrees above zero as I write this (with the high today only four degrees). But there’s a winter storm warning in effect until 3:00 AM tomorrow morning. (Severity: Moderate; Possible threat to life or property.) We’ve had 2.3 inches of snow so far with another 7.2 inches expected.
