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 →

“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.

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 →

The Read

I’m taking a short break from it while I wait for my soup – that wonderful soup I made a huge vat of last night, using the essence of the left over carcass of a roast chicken I served on Christmas day combined with various delicious vegetables from the farmer’s market – to heat up for dinner. I need the break, as I’m mentally exhausted. Although I strongly feel like having a nice evening glass of wine, I am forbidding myself from having one since I must stay sharp for much longer this evening, despite my exhaustion. So a bit of blogging about my ongoing task will somehow serve as my relaxation. Oddly enough. Well, let’s see if it does.

I’ve been wandering an incredibly striking landscape, with such remarkable variety, detail, texture and hue. There are features that move me to tears at times, reduce me to fits of uncontrollable laughter at others, but mostly intense reflection throughout. I should be simply enjoying it for its own sake, drinking it in where I want to, letting it simply wash over me at times, while at others, cupping some of it in my hands and looking at it close up, before letting it flow away and moving on. But I do not have that freedom. Instead I have to look at it all with a view to ranking various features over others – putting it all into some sort of order. This is a terrible task to have to do, since so very much of it is simply wonderful in its own right, and there’s hardly any meaning to ranking some parts over the other.

What on earth am I talking about?

Well, as is so often the case with some of the things I get myself involved in, I can’t tell you much detail, since the process itself is ongoing, and rather sensitive. I’d not […] Click to continue reading this post →

I just thought you’d like to know this. I’m a Specialty Act. Got that?

Last month, just before taping some material for a new TV show (that you can see on a major broadcast network starting in a week or so) I signed some routine documents. One of them involved me ticking a box to specify my official status for […] Click to continue reading this post →

New Voices, Great Name

13point7_roster I noticed yesterday that there’s a new group blog, at NPR, on science and culture, and – to my pleasant surprise – one of the co-authors is my friend and colleague KC Cole, the well known (and quite marvellous) science writer! I’ve met the physicist Marcelo Gleiser who will be a co-author and he seems like an excellent new voice to hear from. Astrophysicist Adam Frank and Biologists Ursula Goodenough and Stuart Kauffman round out the exciting-looking roster. (I cheekily grabbed a screen shot of the roster photos (left) from their site.) There are a number of lovely pieces up on the site already for you to read.

The blog is called 13.7, a number that might be familiar to you.

No? You might be thinking that it is the new high price for a basic over-priced cup of “gourmet” coffee in some new tediously pretentious cafe in LA (and believe me, I’d not be at all surprised), but I was in fact referring to the 13.7 billion years that is the age of our universe. I think that is the primary meaning they had in mind too. I’m pleased to see these new voices in the blogosphere, and pleased that authors of blogs of this sort can still come up with excellent names! 13.7 is a really rather nice name and, in a slightly inside way, captures the scope, variety, and grandeur of the themes I expect they’ll explore in much the same way that the name Cosmic Variance promised (and delivered) for that group blog back in 2005. I came up with that name a little before we launched the blog (we mulled […] Click to continue reading this post →

Final Morsels

cheesy_biscuitsThey’re sitting the final exam for my graduate electromagnetism class right now, having started at the ungodly hour of 8:00am. I’m sitting outside in the bright, lukewarm Winter sun with a cup of coffee, two cheesy biscuits I baked at 6:30am for no reason other than feeling in a baking mood (see right), my phone in case there’s a reason for the TA on duty to contact me, and my iPod, which I am of course using to write to you.

It has been an odd few days. Not so much because of the pair of them that had me wandering around a huge studio lot, being wardrobe-checked and make-up checked, shot from all angles with a live cheering studio audience in attendance (for your viewing pleasure on a new prime-time series on Fox to begin airing next month – more on this later, perhaps), but because early on Saturday I woke up with a severe vertigo attack. vertigoVery odd indeed and although I managed to get it under control and it had worn off over the days, every now and again it gets close to being triggered again. I don’t know the source for sure – I think it was correlated with a reaction to some of the food I had on set, maybe combined somehow with the severe ear blockage I had about a month ago after catching a (short-lived) cold on a long transatlantic flight? – but I have to say (and this is the point of my digression here) that it is a remarkably odd experience for me to feel slightly off balance for such an extended period. I’m used to being on the tips of my toes ready to skitter along the line at the edge of a low wall if the mood takes me while walking along. But I can’t imagine doing that now. I feel like I’ve lost my powers… it’s often amazing to me how little it takes to make a person feel very mortal, even fragile, again. It will no doubt pass.

I’ve been gentle on this final exam. I still find it disturbing that kids today (yes, I said “kids today” – perhaps my lack of equilibrium has put me in crotchety-old-man mode), even the very smart ones, typically do badly on any advanced exam that […] Click to continue reading this post →

MAD to LAX

Well, I’m back.

It is early in the morning, at home. At 5:30 am, with my first cup of tea in hand as I breathe in deeply and simply listen, the rest of the City of Angels seems asleep still. It is covered with a fluffy blanket of grey clouds, and it looks strangely snug under it.

madrid_windows_1It has been quite the trip, as you may have gathered from the past several posts. I managed to get a great deal done in that last day or two, as I was planning when I last reported in. This included more food, jazz, some flamenco in two unexpected but fascinating settings, the excellent collection at Reina Sophia (focused mostly on Picasso), and more.

I’ll try to tell you some of it in the next few days.

But now I must focus on being back. I spent a long day travelling back from MAD to LAX yesterday and need to recover and get on with business immediately. There is a final big lecture for my Electromagnetism class to write and deliver, for example. All […] Click to continue reading this post →

Less Work, More Play

madrid_eating_2Well, the weekend is here and so I have wrapped up most of the official part of my visit to Madrid. Lest you think that I spent most of my time eating (not that there’s anything wrong with that), let me mention that I ended up, from Monday to Thursday giving about eight hours of detailed exposition at the board and fielding questions (the lectures and seminar), umpteen (an official number, I’ll have you know) hours of preparation of the notes needed to do this in a successful and clear way, and several more chunks of time in private physics conversations of various sorts. Quite fulfilling, tiring, but worthwhile for all concerned. (I even heard that various people liked the lectures and the seminar, so that’s a real bonus!) It has been a good week.

Thursday night saw me wandering the city streets in the drizzle for several hours. It all started out with a quick walk near my hotel to see if I could stumble on a restaurant, but eventually turned into a longer walk and then an epic quest, as happens to me so often in such situations. I start applying a list of criteria for what I […] Click to continue reading this post →

hitler_peer_reviewAh yes. I’ll admit it: Except for the moustache and a few other details, the scene is eerily familiar… 😉 (The embed for the video is below.)

Does anyone know who originally started this brilliant series? For those who don’t know it is a 4 minute clip from the 2004 film Der Undergang that several people have periodically re-subtitled with words that have Hitler reacting to an event of some sort. (Warning: Many of them are full of language some might find a bit strong, so watch out!!)

Working and Playing Hard

tapas_madrid_1Well, I’m simply exhausted. I gave my second two-hour lecture today and drained my energy resources quite a bit. This is after an early(ish) start to the morning (7:30am) and with going late to bed last night (1:30am). A good lunch afterward helped restore things to a balance a bit, but I need to rest some more.

I’ve been modifying my lectures during the process of giving them, making adjustments for time and the kind of questions I get. This means that I end up kicking some parts to later lectures, and then trying to spend some of the afternoon writing new material, as well as on the train back to my hotel, and in the evenings.

Well, briefly in the evenings so far. That is because last night was set aside for a tour of some of the tapas you can find in the old part of Madrid. I had the presence of mind to go back to my hotel and get a short nap first, and then met my gracious […] Click to continue reading this post →

Here, There, and Everywhere

british_library_1Well, it has been quite the week so far. I’ve been mostly in England. First I spent Tuesday getting over the main effects of jetlag and a short but strong cold (both more or less gone now), and then Wednesday I went to King’s College London to give a seminar to the three groups in the Triangle series of seminars – King’s, Imperial, Queen Mary are the three places the participating research groups in theoretical high energy physics come from. It was excellent to see so many old friends and colleagues, meet some new ones, and chat physics at the pub and over dinner later on. The seminar seemed to be well received, although I know I was far from my best, given jetlag and cold. The next two days saw me saying hi to family and friends at coffee and dinner in the evenings and visiting at Queen Mary and Imperial for the day, and hiding in the British Library for most of Friday, writing.

What am I writing? Four lectures on D-branes and string theory and M-theory, with a focus on some of the fun and instructive applications (and potential applications) of […] Click to continue reading this post →

The Universe: Cool Cars, Hot Sand, and Fast Balls

flows in death valleyYou may recall my mentioning a desert trip to shoot something for TV, some time back. One done at precisely the wrong time of year. And to Death Valley, one of the hottest places on earth, to boot. Well, I meant to mention that the episode of the History Channel’s The Universe that the shoot was for aired a week or two ago and it was really excellent. It was entitled “Liquid Universe” and it was a rather beautiful and thoroughly pleasant episode exploring the role of liquids in our universe, a matter not often raised in questions of astronomy except when it comes to matters of water from time to time. This was not about water per se, but rather the whole matter of material that flows and the role it plays in diverse areas of the solar system and perhaps the universe at large. I was using sand to demonstrate how sometimes there are surprising places where you can find fluid/liquid behaviour, and mentioned some of the new phases of matter found in the context, for example, of quarks and gluons at RHIC. (I’ve spoken about that here a number of times in the context of some of my research. See the archives.)

It was an excellent episode and another example of how one can take a topic under the “The Universe” heading and showcase lots of exciting science quite accessibly […] Click to continue reading this post →
