Acrobatic Angular Momentum

airealistic_at_edisonIt was a routine Wednesday night down at the Edison bar, downtown Los Angeles, last week. This means: Fun with Acrobats!! It is part of their weekly “Incandescence: the Dark Side of Light” series, where throughout the night there are performers all over the floor of the bar, more set piece things on the stage, and rather splendid feats being performed from various points of the ceiling. The theatre group is called AiRealistic.

I thought I’d make a little film for you, of what (come to think of it) might make […] Click to continue reading this post

Michael Jackson and D-Branes

A D-braneWell, I bet you have not read any articles connecting Michael Jackson and research in string theory before. No, even though I spend a lot of time and effort trying to bring science into everyday conversations people have about the broader culture, I cannot claim credit for this one. I was reading an excellent article* in the Village Voice written by Greg Tate, and to my surprise, there it was. It is by far the most thoughtful and insightful of any of the articles on Michael Jackson that I’ve read, and I’d already concluded that before noticing any mention of physics. I strongly recommend it, especially if you don’t know what all the fuss is about, or if you think that the fuss is only about some pop music.

Tate examines not just the impact of Jackson on the culture, and where he sits in the pantheon of black people who have made such impact (he’s mostly focusing on America), but also the role of adversity and struggle in focusing talent in a way that produces people who create at such a high level and which such seismic effect. He […] Click to continue reading this post

News From The Front, VII: What is Fundamental, Anyway?

One of the words I dislike most in my field – or more accurately, a common usage thereof – is “fundamental”. This is because it is usually used as a weapon, very often by people in my area of physics (largely concerned with particle physics, high energy physics, origins questions and so forth), to dismiss the work of others as somehow uninteresting or irrelevant. image by I don’t like this. Never have. Not only is it often allied to a great deal of arrogance and misplaced swagger, it is often just plain short-sighted, since you never know where good ideas and techniques will come from. A glance at the history of physics shows just how much cross-pollination there is between fields in terms of ideas and techniques. You never know for sure where valuable insights into certain kinds of problems may come from.

Fundamental physics is a term I used to hear used a lot to refer to particle physics (also called high energy physics a lot more these days). This was especially true some years back when I was an undergraduate in the UK, and it persisted in graduate school too, and is still in use today, although I think it is declining a bit in favour of less loaded terms. Somehow, a lot of particle physics is regarded as being all about the “what is everything made of at the very smallest scales” sort of question, first discussing atoms, and then atoms being made of electrons surrounding a nucleus, and the nucleus being made of protons and neutrons, and those in turn being made of quarks, and so on, in this was arriving at a list of “fundamental” particles. There’s the parallel discussion about the “fundamental” forces (e.g., electromagnetism and the nuclear forces) being described in terms of exchanges of particles like photons, gluons, and W and Z particles and so forth. There’s no real harm in the use of the term fundamental in this context, but this is about where the word gets elevated beyond its usefulness and starts becoming a hurdle to progress, and then a barrier. Somehow, “fundamental”, meaning “building block” gets turned, oddly, into “most important”. The issue of what the smallest building blocks are gets elevated to the most important quest, when it is in reality only a component of the story. It is rather like saying that the most important things about the Taj Mahal are the beautiful stones, tiles, and other components from which it is constructed.

Perspectives have evolved a bit since my salad days, with the rise of wider […] Click to continue reading this post
