Lewis Black on set of Root of All EvilWell, Comedy Central fans, here’s something for you. Before you get settled into your nightly dose of the Daily Show on Wednesday night, tune in half an hour earlier, at 10:30 (at least on the coasts). It’s Lewis Black’s new show “Root of All Evil”, this week covering the issue of which of the two prevailing juggernauts in our culture, American Idol or High School, that reduce so much in our culture to popularity contests, is more Evil.

(This one I actually think speaks to a serious point. Sadly, in an presidential election year here, any attempt to parody this sort of thing for comedic effect is totally outshone by almost any news broadcast.)

John Wheeler, 1911-2008

john wheeler in 1967 - New York Times

Another giant moves on. John Wheeler died yesterday. He’s known for bringing to light many wonderful pieces of physics (he’s also credited for coining the term “black hole”), classical and quantum (helping craft many of the ideas surrounding issues in quantum gravity, for example), and for being a great teacher. There’s an obituary* by Dennis Overbye in the New York Times here. I’ve borrowed their lovely photograph (which was given no photographer credit, so I cannot).

[Update: Daniel Holz has a personal reflection here.]

Frank Common Sense

Did you catch the discussion on NPR’s Science Friday just past? I was particularly pleased to hear some calm, thoughtful responses from someone who definitely knows his way around the issue, on a major broadcast. What issue? Whether or not we high energy physicists are carefully endangering planet earth (or even the whole universe) by switching on the Large Hadron Collider (LHC) later this year (or whenever it is due to start collisions). You’ll recall the lawsuit, since I posted on it here (with links to other thoughts), and perhaps you even recall my April Fool post on the matter.

Well, Ira Flatow was talking to Frank Wilczek! It was a good, informed chat around the issues that also gave Frank a chance to explain a little about what the machine was really constructed for (since this seems to so easily fall out of these public discussions of black holes and extra dimensions and strangelets (interesting as they are), and to plug his book that is due to come out. Since it’ll almost certainly be a really interesting […] Click to continue reading this post →

I’m Just Driver

I should really start a new series of posts with the title “What Could Possibly Go Wrong…?” This story from yesterday would be a fitting entry…

Did you see Cronenberg’s “Eastern Promises” last year? It was excellent, and of course totally overlooked in the recent discussions about good films of last year. It was released and seen by most people way too early in the year. Hollywood’s memory is not very good at recalling anything that came out earlier than the Fall if it did not come with a huge bang of publicity and so forth (like the excellent Bourne Ultimatum). Well, just for a moment there, I was in an American version of the film. (Setting-wise I mean. The film is set in a gritty, realistic not-Four-Weddings-or-Bridget-Jones London.) I was in New Jersey yesterday just for the day. (I’ll tell you more about it later.) Here’s what happened.

Papa’s Got A Brand New Bag (Again)

(The title refers to this post.)

Ok, this is a post of (probably pointless) complaint about one of society’s conventions. I do that from time to time. So as I said in an earlier post, I lost my bag within which I carry around my personal day to day stuff. It is small and fits on my shoulder and carries lots of useful stuff that I don’t like to carry in my pockets. My handbag, if you will. I happily carry such a bag, and call it by that name quite often. Sometimes I jokingly say that I’m “secure enough in my sexuality to call it what it is”, and not have to lamely resort to inventing a new name for something that already exists in the world serving that exact function – but carried by women. I’d forgotten just how serious and non-joking this whole business actually is. I did not recall how much trouble I’d previously gone to when I tried to find such a bag that suits my needs (practical and aesthetic). It’s a real pain. Losing it now meant that I had to go through this all over again, and discovering that I’d not really finished the job that previous time. (And the alternative names are so stupid – “manbag”, “murse”, etc… Haven’t they noticed that “handbag” is already gender neutral?)

What is the problem? Simply put, there’s an unbelievable amount of phobia here (and it is here in the USA more than, say Europe) about guys carrying such bags. Utterly […] Click to continue reading this post →

clouds near amarilloThis was not the time to break my over a decade long run of not flying American Airlines. I pretty much only fly United when doing most travel, but I had no choice for this trip from LA to Amarillo, Texas. It was a quick hop there and back in about 36 hours to take part in a rather important event – Andrew Chamblin (a friend and colleague who, you may know, died tragically in 2006) was being inducted into the Hall of Fame of his old High School and so I went along to take part in the ceremony with his family and some of his friends, and address (briefly) the assembled student body (it was such an honour to be asked […] Click to continue reading this post →

Takuya Okuda talking at the SCSS at UCLA, Dec. 2007

Takuya Okuda talking about Wilson Loops at the most recent SCSS, UCLA, Dec. 2007. Click to enlarge.

The next regional string meeting is a two-day one at Caltech, this Friday and Saturday, organized by Joseph Marsano. It’s going to be full of interesting talks and conversations, as usual. Please encourage your graduate students to come, especially, since special effort is made to make sure that each talk begins with a pedagogical portion to help non-experts in that subfield navigate and see the motivation.

The speakers are: […] Click to continue reading this post →

Kobe as Einstein

Did you see the Nike commercial with Kobe Bryant as Einstein?

Kobe Bryant as Albert Einstein

It is part of a series with the theme “genius”, in which he plays a variety of historical figures with a reputation for innovation. More (including the video) on Bryant’s website, and there’s a breakdown by fliptomato on his blog (where I found this).

Given the opening line of fliptomato’s blog post, I wonder if he (or the commercial makers) knows about the excellent Gary Larson cartoon from very many years back […] Click to continue reading this post →

Consider the Alternatives

multiple parallel branes, often used as central idea of alternative universesTomorrow I’m shooting all day for a TV show that is going to focus on the idea of alternative universes (or parallel universes, if you prefer). Should be fun. The setting at least will be interesting (more on that later) and it ought to be interesting to see how the writer puts all the material together into a coherent narrative. Part of my job will be to try to emphasize that while parallel/alternative universes show up a lot in actual scientific discussions (and have done for a long time), we have not yet had anything like a good observational or experimental reason to believe in their existence anywhere other than in our imaginations. It’s vital to get this across (I hope they don’t just edit it out) because people are so willing to believe in many half-baked fanciful ideas – and this is one of them – and when they show up in a science documentary (this is (again) for the History Channel’s “The Universe” series, which has been very good) with actual scientists being quoted, one should be especially careful (as we were on the “Cosmic Holes” episode (with different filmmakers), which has proven to be rather popular, and is full of speculative ideas like travel using wormholes and time machines right alongside equally fantastic-sounding things, like black holes, which are in fact a scientific reality). The rest of my job will be to talk about some of the places where the idea shows up in modern thought, some of the reasons why, and some of the opportunities for solving various challenging problems (and maybe creating a host of others!!) can be afforded by such ideas.

All that aside, this reminds me of something else entirely – Do you ever have those days when you feel like you’ve accidentally stepped sideways into an alternative universe? I do. Recently, I had a huge dose of it. Sit back and I’ll tell you the story…[…] Click to continue reading this post →

All Creatures Great and Small

The previous post was a farewell to black holes in the class, not here on the blog. (And it was not quite a farewell there either, since the midterm yesterday was all about the properties of the Reissner-Nordstrom black hole, representing a black hole with an electric charge, and a nice computation involving cosmic censorship.)

There have been two rather notable discoveries in the black hole astrophysics world this week. The first is the discovery of what seems to be another case of an intermediate mass black hole (there was only one example known before). Not the supermassive ones that live at the centers of galaxies (tens to hundreds of millions of times the mass of our sun), and not stellar mass ones of a few times the mass of our […] Click to continue reading this post →

A Farewell to Black Holes

Yesterday here at USC was my last lecture in the class about black holes (see also here). We’ve got to move on to other topics (Cosmology, Einstein’s equations, etc) and so cannot do any more. It was a fun last lecture though. I pulled together a few scraps of things I did not finish in the previous lecture (such as the extraordinarily high percentage of binding energy per unit rest mass you can extract with rotating black hole orbits – just what you need to power things like quasars) and then finished with:

  1. A taste of Hawking radiation, the Bekenstein-Hawking entropy and the wonderful and beautiful subject of black hole thermodynamics that opens up when you combine gravity with quantum mechanics*, followed by…
  2. A quick discussion of the Penrose process for extracting energy from rotating black holes. (I’m sure that all (past, present or future) super-advanced civilizations must be using them as the ultimate emissions-free means of generating energy for heating their homes and so forth. No, really.)

*Of course, all undergraduates commonly hate it when you dare bring in stuff from other classes, so to […] Click to continue reading this post →

More Trouble for LHC?

[Update:- NB: This was an April Fool joke. -cvj]

CMS detector - New York TimesSome breaking news for a change. I’ve only heard snippets of this and so I’ll update later with more as I get it. That silliness that was in the news about two physicists pursuing a lawsuit against the Large Hadron Collider has suddenly become serious. (Image right: the CMS detector at the LHC, taken by Valerio Mezzanotti – from a NYT article last year.)

Recall that the issue was that there would be the possibility of the experiment creating mini black holes that could gobble up the earth and that the CERN scientists have not done enough to demonstrate that this was not a safety issue. Of course, and has already been said in several places (see e.g., Phil’s general level post about the physics and the case here), this is utterly ill-conceived and in any case certainly not the way to go about things, but it seems that the legal route can be quite damaging for science, in the right hands.

What seems to have happened is this. Since the suit was filed in Hawaii, it falls under US Federal jurisdiction, and has been taken up as an emergency issue before the Supreme Court. Somehow the litigants got a hearing on this with the help of powerful friends who have what can only be thought of as another example of the anti-science agenda we’ve a lot of in various branches of the government in recent years.

The upshot is that the Supreme Court has announced today that they are requiring all […] Click to continue reading this post →
