Gunslinging Bohr

bohr_einsteinThis story has come along at just the right time, given that my last post was about Einstein. Seems that Niels Bohr (another giant from the same period, and another one of the founders of the quantum theory) was a big fan of cowboy movies, and thought a lot about gunfights. Yes, really! (There he is in the photo on the left hanging out with his friend Einstein in later years, perhaps 1925. Perhaps they’re at a drive-in movie? I got this photo here.)

It turns out to be all relevant to new studies about reaction time. The fastest person to draw does not necessarily win the gunfight: […] Click to continue reading this post →

Crazy Al

So I was chatting with a friend of mine the other day about science and scientists, and in particular what on earth we theoretical physicists actually do.

She (mostly jokingly I think) said we’re really all a bit weird, just sitting around thinking about quantum physics all day. einstein_imagesI tried to begin to explain that we don’t sit around thinking about quantum mechanics all day any more than a tailor sits around all day thinking about needles. (Or how many angels or demons can fly through the eyes of said needles at the same time.) No, we’re mostly getting on with using the needles in the making of new suits and so forth. (To continue the allegory.)

But I did not get to that analogy, because another thing came up. She went on to say “…like Einstein, with crazy hair…”, to invoke her primary example of the crazy quantum scientist. Now, given that she was talking to me (er… no crazy hair, in case you are wondering), she was clearly joking, but in my view, at the core of all that is a serious image problem that science has to deal with – bizarre cliches about who we are and what we look like. So I thought I’d point something out.

The most famous image of the crazy/eccentric scientist is largely based on a lie (or […] Click to continue reading this post →

Comments Off on Mathematics in Your Business

Terry Gross interviewed Scott Patterson and Ed Thorp on NPR’s Fresh Air. I heard it yesterday. It was very interesting to listen to Thorp in particular, a mathematician, describing his curiosity about how to construct a system for beating various gambling games, and going from there to the stock market, in effect becoming one of the earliest of the “quants”,

Thorp and the people who use such systems have come to be known as “quants” — it’s a reference to the quantitative-analysis techniques they employ — and their stories are told in Scott Patterson’s new book The Quants: How a New Breed of Math Whizzes Conquered Wall Street and Nearly Destroyed It.

You can hear the interview here, and read an extract from the book. Very interesting are the questions about what they think really went wrong in the market crash of […] Click to continue reading this post →

You Don’t Need Magic To Use Energy Wisely

energy_posterThis is a fun poster I saw at the Grove the other day. (Click for a larger view.)

The good fairy (Tinkerbell, apparently) speaks the truth!

It’s nice to see such a campaign, and aimed at the younger set (who in turn might bug their parents into thinking about it too). It is sponsored by the Department of Energy (the same people who sponsor most of my research), and you can look at the website here. Maybe you’ll direct some others to it too! There’s an energy action checklist, and lots of useful tips and guidelines for everyone (young and old) to follow in order […] Click to continue reading this post →

Meteorite Men!

Comments Off on Meteorite Men!

meteorite_men Did you watch Meteorite Men last week? If not, you can probably catch a repeat. It is a new series, airing 9pm ET/PT Wednesday nights, on the Science Channel about two guys who search for meteorites. Check your local listings for times. (Photo cheekily snapped from their site. Copyright aerolite meteorites.)

I learned about it from Bob Melisso, my producer/filmmaker friend (and occasional collaborator: see here, here and here) who made the pilot and is the supervising producer for the series. From […] Click to continue reading this post →

Gaiman in the New Yorker

4 Comments

This week’s New Yorker has an article by Dana Goodyear on Neil Gaiman. There’s also an online chat with him and Goodyear and readers here. I like a lot of Gaiman’s writing and am impressed with his imagination. It is interesting to note that such a prolific and influential talent has managed to not become a household name. This might be beginning to change. As a result I myself a bit conflicted, as I often am in this situation when someone like this, whose work I’ve followed for years (or that I’ve simply privately noted is really excellent, early on), is maybe about to break into mainstream recognition. I’m happy for them, want to share them with my friends and the world at large while at the same time being a bit worried about it having […] Click to continue reading this post →

On Art, Fairy Tales, and Creativity

“If you want your children to be intelligent, read them fairy tales. If you want them to be more intelligent, read them more fairy tales.”

Do you know who said that? I’ll break the post here to give you a moment to think about it. I’m not going to ask for the answer in the comments since you have Google on your side, but you can, if you like, share in the comments whether you knew or guessed it right before you moved to the rest of the post below to learn the answer. (Image above is an illustration by Walter Crane for ‘Snow White’ (1882).) Continuing… […] Click to continue reading this post →

Cameron and Avatar

Somehow I forgot to point this out last Fall. There was an interesting article by Dana Goodyear in the New Yorker on James Cameron, creator of so many giant films you may know of, and of course, of the recent juggernaut Avatar. It is definitely worth a read, as is Goodyear’s related chat online with readers here.

I went to see Avatar in its proper setting (late night showing in the Dome at the Arclight of course) a fortnight ago and can report a few things of interest:

* The cheeky alternate name Smurfohantas (I heard this name on Kermode and Mayo’s BBC Radio 5 show) is not far off the mark if you are in a cynical mood. It’s a very standard story, rather straightforwardly told, but using striking tall blue people. (There is nothing wrong with re-telling stories, by the way, so don’t get me wrong. Arguably, most stories are in large part old stories). I just don’t see this version as particularly well told, just merely functional. There’s a slightly more interesting angle buried under there somewhere about the whole idea of avatars, and maybe even something about disability, and so forth, but only if you really really dig for it.

* It is not a great film, but it is an interesting and entertaining film to watch. I have a soft spot for Cameron’s work since I do like his use of strong female characters in the genre as well as his anti-war, suspicion-of-corporation, and environmental […] Click to continue reading this post →

News From The Front, VIII: One Down…

work_snap…more to go. I’ve finished one of the papers I’ve been writing (this one co-authored with my student, Tameem) after delaying on it for months. I’m not sure how things got quite this backed up in terms of things I have to do, but they have. I meant to start on a new, long project last week, and all my efforts these days have been toward clearing away all those things I want to get done and dusted before focusing on that. It is taking time, but gradually the clearing is happening. Two more manuscripts to complete.

This paper reports on the continuation of the work we’ve been doing over the years in understanding the physics of various model systems in an applied magnetic field. This is in the context of holographic models of important strongly coupled phenomena that are of considerable interest in lots of fields of physics (particle physics, nuclear physics, condensed matter physics, atomic physics). (Since I don’t want to explain holography and so forth every time I talk about it, see a post I did about some of that here, and related posts in the list at the bottom of this one, if not sure what I’m talking about.) (Hmmmm, I see from my SPIRES listing that I’ve got seven papers mentioning magnetic field explicitly in the title in the last three years, and three or four more of the rest are occupied in large part with the issue too. No, really, I’m not obsessed.)

The issue here is the study of structures that suggest themselves as earmarks of Fermi surfaces in strongly coupled systems. It has been a goal for a long time in the context of gauge/gravity duals to understand what the signals of a Fermi surface would be. Would it be some geometrical object in the dual gravity theory, perhaps? Access to a computationally tractable description of such an object would be rather […] Click to continue reading this post →

Stormy Weather

rain_fullWe’ve been having wonderful storms here the last few days, and it is expected that it will remain like this through Sunday. It has been great. There’s something wonderful to me about torrential rain pouring down outside through the day while I’m inside working, glancing out of the windows from time to time, and making endless cups of tea. In the afternoon there usually is a break in it all. The sky clears a little, […] Click to continue reading this post →

eric_lewisI went to a friend’s birthday party last night and… Eric Lewis was there, playing the piano throughout the night! He’s a master in all styles, it seems, including classic and contemporary Jazz, through Happy Birthday to masterful renditions (and deconstructions) of pop, R&B, and soul tunes (there was a lot of spontaneous gathering and singing around the piano). I found some videos on YouTube for you.

It’s a Feel-Good Movie!

By | | ,

scene_from_the_roadI’m puzzled. Almost everything I’ve heard from people – even otherwise thought-provoking respected film critics – is that John Hillcoat’s film of Cormac McCarthy’s wonderful novel The Road is really depressing. I think that the problem might be that there’s a lot of looking at the obvious images on the screen (a defeated, broken, decaying landscape) and rushing to a conclusion because there is the odd perception that the first thing that comes to mind (or the first emotion that is awoken in the viewer) must be the primary content. I find this odd, since there’s so much more there, and it shows up only slightly below the surface.

In fact, I’d go as far as saying that The Road is up there as one of the top three “feel-good movies” of 2009, if that term was ever worth using. Yes. Feel-good. This is a term that is mostly used for some of the (and I am being generous) often […] Click to continue reading this post →

How to Help

haitiThe Daily Beast has a good list, with donation links, of many NGOs on the ground in Haiti that you can pick from to help out*. (Map right from Lonely Planet.)

Please go and have a look, and make your choice.

If you’re really too busy, consider the texting options. You send a text message to a number and it results in a donation that is later deducted from your phone bill. A pair of examples:

Text HAITI to 90999 ($10 to Red Cross)
Text YELE to 501501 ($5 to Yéle, Wyclef Jean’s development organization.)
