When Physicists Go Bad?

billy cottrellI’m rather shocked by this story, and feel compelled to draw it to your attention. This week’s LA Weekly’s cover story is by Judith Lewis, and it is a very detailed account of what’s been happening to Billy Cottrell since you probably last heard about him. He was convicted for his role in various arson attacks on SUV dealerships in the Pasadena area, and sent to prison. Just to remind you, Billy Cottrell was a graduate student in theoretical physics working with colleagues of mine just up the road at Caltech, and so it has even more resonance as a story than normal, since even though I never knew him, he -or his type- is so familiar to many of us, right down to the youthful fascination with Euler’s eiÏ€ + 1 = 0. (Apparently he left that written at some of the crime scenes…)

torched hummersI leave a question mark in the title of this post for lots of reasons: Just how “bad” was he in the first place? Had some of the vehicles that were damaged not been from out of state, the crimes would not have been Federal matters, and the full weight of the crimes being labeled acts of terrorism (and all that brings with it in today’s atmosphere) would not have transpired. The judge seems also to have simply added three years to his sentence on a whim. His having Asperger’s syndrome was never allowed to be mentioned in the case at all, and so the jury was never given the opportunity to consider that some particular behavioural characteristics (in the course of the crimes themselves, and in the course of the courtroom defense) might have been exacerbated by it. The list of things goes on.

But since his sentencing, things have got even worse. It’s just dreadful. The terrorist Click to continue reading this post →

Richard Massey

Well, yesterday’s colloquium by Caltech’s Richard Massey was a lot of fun, and really excellent. When faculty, postdocs and students are all chatting about it afterwards, you know it went well. This is what a departmental colloquium is supposed to do, and it happens when subject, level of delivery and speaker all come together in just the right way.

Grindhouse Marathon

I just learned of this festival, starting tonight at the New Beverly Cinema. I thought I should tell you about it in case you’re able to go. Also, it’s just fun to remember some of the movies in this genre, or some of the modern movies that celebrate, quote from, or were otherwise influenced by them. The festival should be a lot of fun!

It’s a Quentin Tarantino project, and there’s more at the cinema’s website, and an truly excellent post about it at the blog “Sergio Leone and the Infield Fly Rule”, which early on has this excellent paragraph:

the mack posterThe director has responded to the New Beverly’s generosity by lining up a gut-bucket cornucopia of authentic grindhouse trash cinema to celebrate not only his supermanchu poster upcoming movie, but the whole experience of seeing sleazy cinema classics in the only movie house left in L.A. (outside of the Vine on Hollywood Boulevard) that feels physically, spatially and, yes, spiritually related to the downtown second-run trash palaces that fed Tarantino’s (and everyone else’s) desire for this kind of rotgut, low-rent fun to begin with.

…and then goes on to do a wonderful thing by finding as many of the original movie posters (or related artwork) for each movie. It’s great to look at, and there’s a rather Click to continue reading this post →

Lots of good material here… so little time. I particularly want to read Chaplin’s and Kandel’s but the others look so good too. More about the complete list in all nine Click to continue reading this post →

When Worlds Collide, I

Angeleno magazine Robert Downey JrA most striking representative of an item from a completely different world than mine is the magazine Angeleno. It is among the most glossy of the glossy magazines I’ve ever seen. I’ve no really strong idea of who its intended readership is – this has been a mystery to me for so long, but by default it clearly can’t be someone like me (an academic), I decided upon first seeing it. (You can read about the raison d’être of their parent company, Modern Luxury, here.) For some reason it arrives (for free although the cover price is $5.95) in my mailbox every month and I don’t know why. It is almost as though it’s a joke on the part of some prankster deity or other.

It has nevertheless done an excellent job of sneaking past my defenses. I don’t immediately throw it away when I receive it, and I find myself alternately annoyed and fascinated by it. Could this have been part of their plan all along?

It used to be that I was just plain annoyed when it would arrive – as much as 1/2 an inch thick, larger in square footage than most other magazines, highly airbrushed A-list star on the cover, and every page super glossy and shiny – and it would sit there for weeks until I’d find myself glancing inside it … just to confirm that I was justified in my righteous annoyance, you see. Sure enough, it would not disappoint. It has pieces devoted to ways of spending oodles of money on pointless stuff at extraordinary prices. There’s be the hot new treatments (“is Fraxel the new Botox?”). There’d be a gaudy diamond-encrusted PDA for your microscopic toy dog, that you Click to continue reading this post →

You Can View Point of View

Well, the video of the Point of View event of a couple of weeks ago is now available. Click here for streaming media. There’s a problem, however. While my opening off-the-cuff remarks are utterly unimportant, and so it is not a big deal that the audio of that is poor, the big problem is in the third segment. Apparently (according to the A/V person) the Bluetooth microphone that they were using to capture the sound for the video camera must have used up its battery, as all the audio for USC’s Cinematic Click to continue reading this post →

On Language in Science and Beyond

By | | , , ,

In Physics Today last month, Helen Quinn wrote rather well about the issue of language in science and in common (non-scientific) usage, with a focus on when the two collide. I recommend the article, which you can read here.

There are cases in our own teaching where confusions arise, which mostly get resolved as the students learn the concepts associated to specific words….

A few words in elementary physics— force, work, momentum, and energy—have carefully defined physics meanings. Their much broader everyday usage causes students a great deal of confusion until they learn the precise physics concepts.

…but she’s much more interested in the cases where some words -often powerful ones, commonly invoked- contribute to “considerable public misunderstanding of science”:

belief, hypothesis, theory, and knowledge.

None of these words has a unique physics meaning, but their meanings as we use them among ourselves and as non-scientists hear them are very different. We need to be much more careful how and when we use them in talking to the public.

She goes on to discuss them in turn. I recommend reading it in full. One of the things I like most about the article is that she talks not only about the process of using those Click to continue reading this post →

Show and Tell

Well, it is almost the last day of Black History Month and I am behind on answering the traditional emails I receive at this time of year. As I said last year (with a few modifications):

clifford v. johnson at the board Pretty soon after February starts, the deluge of email I get every day gets enhanced a bit by emails from students from all over America. I become part of an assignment, you see. It seems that these students are instructed to find a black scientist and write something about them and do a presentation to their class about them1.

I’m always willing to help with this sort of thing (see the footnote for why), and so I usually send some links: to my personal webpage (here), or one of two profile pages for me at USC here and here (the latter by Katherine Yungmee Kim), a Daily Trojan news story by Diya Chacko here, or the departmental page on me (here), and a list of publications, and I hope that this is all of some use.

As to the standard “what is your date of birth?” question that is usually asked too, I don’t pass out that information over the web, but if you’re an interested student, you can email me for a bit more information if you wish, although I will not give out the exact date.

For a bit of biographical narrative, students can look on the “My Hero Project” Click to continue reading this post →

Well, I’m sorry if things have been a bit quiet around here for a bit. I’ve been very busy, and also eight hours out of sync with my usual cycle. Couple this to also being disconnected from the web in the second hotel I was staying in because of me being too cheap to pay the extortionate amount that they were asking for a connection (the other place had a free connection in certain public lounges, and luckily the signal leaked into my room enough to get me a good connection a lot of the time) and you get quite a bit of quiet.

New Directions in Real Estate?

keats real estate imageOn NPR’s finance programme Marketplace yesterday, there was a somewhat unusual piece. It seems that conceptual artist Jonathan Keats is making some money by selling the extra dimensional rights to various properties in San Francisco! (You can see him at the Modernism Gallery there1).

Since there’s no known way to build on or otherwise occupy this new extra dimensional property (let me explain a bit further in an enormous footnote2), the prices are awfully reasonable. Here’s a transcript of a transaction that I found on their website. Reporter Nathaneal Johnson is observing a sale to punters Oscar Villalon and Mary Ladd:

Light Seen Down Under?

compact fluorescent bulbincandescent bulbI’ve been meaning to post about this for a few days*. It has since made it to rather high visibility in the news, I’m pleased to see, generating a lot of interesting discussion. The Australians (another nation not part of the original Kyoto agreement, notably) have pushed ahead on the issue of trying to legislatively encourage (shall we say) the use of compact fluorescent light bulbs over the more wasteful traditional incandescent bulbs.

You’ll recall my posting about this idea not long ago, in the context of proposed California legislation (so yes, I used the same images in the same way). Now, I’ll admit that I was thinking of that as a test case, and when things are ironed out into a workable legislation there one would imagine the model being rolled out to the rest of the world to adopt in their own fashion. I did not expect an entire country to adopt it so soon and at such a rate (they propose to stop sales of incandescents by 2010!).

We had a lot of discussion in that earlier thread about the pros and cons of this. Commenter IrrationalPoint (IP), for example, seems convinced that this represents a serious access problem for people who respond less favourably to the new lights. Such legislation is therefore discriminatory. My response to that was in several parts. The first is that I was not convinced that the cited flicker problems were really problems that referred to the new bulbs. They don’t work like the old nasty fluorescents we remember from years back, or that are still to be found in a lot of public spaces. Their flicker rate is up at tens of KHz, not the 60 Hz of old. IP (and one or two others) then suggested that the issues were with the spectrum. My response there was that the spectrum is quite a bit different from a lot fo the old lights, and where some discomfort might arise with the new ones, this is possibly only a problem for some if direct lighting from the light bulb is used. (I personally find direct light from incandescents pretty disturbing in a lot of cases too.) Why not use the bulbs in conjunction with a simple filter or other decorative fixture that can modify the light to your tastes?

But I am keeping an open mind on this. Perhaps I’m just wrong, and the whole idea of banning incandescents is unworkable and insensitive, but I am not convinced that work cannot be done to make sure that it works well for all concerned.

One of the biggest problems with the discussion is that nobody could point to good Click to continue reading this post →

That Feeling

By | | , , , ,

It is on the list of my top five all-time favourite feelings. But I know of no word for it in English that properly captures it. This is strange, since so much of our society relies on things that probably came about in accompaniment with this feeling. I’m sure you know what I’m talking about. Sometimes it come on so strongly that it feels like a switch has been flicked inside my head, with an almost audible “click”, often accompanied by a smile, an oral exclamation, or even a moan. Why can I not think of a word for it? Perhaps my vocabulary is failing me, but if there is not such a word, then we should set about forging a new one, since it is so important.

What am I talking about?
