A Retreat

sketches for studyAs I get older and busier, I seem to increasingly value quiet spaces. I always loved them, but now they seem more vital to me than ever. So I seek them out constantly. It’s important to note that it is, as they say, all relative. My whole house is a quiet space in a quiet part of a neighbourhood, which is itself in a relatively quiet part of the city. Nevertheless, I’ve been monitoring my working patterns of late and noticed quite a bit of fragmentation, which bothers me a lot. Sure, a lot of it is self-inflicted (email, blogging, and so forth can always be managed better – that’s another issue to discuss), but some of it has to do with finding good spaces to work, depending upon the type of mood and type of work to hand.

I’ve lots of favourites, and many of them are cafes and bars around the city, some places on campus (my office is not high on that list though), the odd bench in a park here and there, and so forth. But those are mostly for working in my “public space” mode. Sometimes I want to work in a different mode, or sometimes I want to just stay […] Click to continue reading this post →

’Twas the Night Before Finals…

Comments Off on ’Twas the Night Before Finals…

My always-ignored advice to anyone studying for exams is that the best thing you can do the night before is get a good night’s sleep. Long study periods long before the previous night should have been used to build up your skills and knowledge. Late-night cramming at the expense of being fresh and having your wits about you in the morning is not really going to help much, if at all. (Heh… long study periods….call me old-fashioned.)

On this very matter, Yvette (one of our regular commenters here) has outdone herself once again with her literary skills! Here is part of her seasonal (as in finals season) poem:

The Night Before Finals

By Yvette Cendes

T’was the night before finals
And all through the dorm
Crazed cramming and panic
Was quite the norm.

The students were restless
And none touched their beds
While theorems and formulas
Danced in their heads.

With textbook in hand […]

Finally

Well, it’s been a crazy week here in my corner of the universe. I’m still trying to find the time to break off from several things in order to update you on things from last week and the week before. Meanwhile, new things have this way of happening anyway, and sometimes I’d like to mention them too. So it is with teaching matters. Two Fridays ago was the last lecture of my electricity and magnetism class. We’d done magnetization, they’d waded through another couple of class worksheets I prepared for them on the topic, we’d remarked upon similarities and differences with respect to polarization in the electric case, and with a few hints about what phenomena were to come when they do electrodynamics (the second part of the course – we’d strictly been dealing with statics) a feeling of some sadness came over me as I said the last words of the class. I’d liked this group. They got it. I was going to take them out of their comfort zone and get them to work a bit harder and stretch themselves a bit harder, and the benefits (I hope) became apparent to them when they could see further, run faster, and jump higher (with respect to their abilities as physicists, I mean). (See some earlier thoughts on that here, as I prepared to start teaching the class.) They responded well by not whining about the extra effort required, but instead rolling up their sleeves and having a go, with good humour, a good sense of camaraderie, and remaining reasonably engaged and interactive right down to the very last lecture. They got it. I love it when that happens.

My Work Here is Done

lexington visit Yep. All done. Sitting in great cafe with a cup of camomile, listening to one of my favourite Mingus albums on the cafe’s overhead speakers, feeling that it all went well. (The latter – Mingus in a great cafe late at night? – is not really the Kentucky I remember.) I seem to have gone three for three. Class, seminar, colloquium. No disasters, besides skimping on the sleep a bit here and there and writing some of the material at the last minute. Good.

So I gave the seminar at noon, talking about much the same material I did in my Santa Barbara talk I mentioned before here. We then went to lunch at a Korean place nearby that was rather good. I ordered the bi bim bap (as I often do at Korean places) and to my disappointment, it did not come in the super high temperature near-molten […] Click to continue reading this post →

A Return

I’m in Lexington, Kentucky, for a couple of days to give three presentations at the University of Kentucky (or “UK” as everyone refers to it here – I hope that explains the previous post). I should be preparing two of them instead of blogging, but… you know how it is. Here’s how I got here:

lexington visit On Wednesday afternoon, after a class on magnetostatics, and an attendance of a lunchtime event where four of our faculty (Biology, Geology, Cosmology (our very own Elena Pierpaoli!), Biology) presented their research, I dashed for a plane. Some hours later, at 10:45pm local time, I touched down in Chicago, and 15 minutes later was on the highway in the company (and car) of Nick Halmagyi.

Our mission? To hang out for a few hours in an excellent bar or two of his acquaintance and catch up on what’s been going on with each other, workwise and otherwise. The Charleston was indeed excellent, and (after chortling a bit about the memory of my annoyance at being charged $29 for a serving of a single malt scotch in a bar in Aspen during the Summer) proceeded to order the same here (he the Macallan, me the Talisker). At about 1:00am, the music stops and a guy with a face full of character sits down at the upright piano, is introduced to a scattering of applause, and proceeds to play some Chopin. Everybody shuts up and turns to listen. Appropriately, the piano sounds like all upright pianos in all bars all around the world sound (the tuning is just a bit wobbly), and the guy is good – really good. He stops playing the piece, and there’s some more scattered applause; someone (jokingly?) offers his a dollar as he walks away which he waves away enthusiastically; the music comes back up, and everybody turns back to their conversations. Nick and I continue to chat about various aspects of life, and order a couple more whiskeys.

At 1:25am or so we wander over to another bar. Nick seems a bit surprised by my suggestion to do this (‘cos I’m supposed to be going to sleep), but I’m just enjoying walking for a bit in the cold, wearing a cozy hat and coat that normally get no use these days, and there’s something nice about a proper bar hop in a neighbourhood with good bars and in the company of someone who appreciates it. This bar has an […] Click to continue reading this post →

All in a Weekend’s Work and Play

I’ve been distracted by several things recently, and so (even more than is usually the case) there’s far more to report than there is time to report it. Among the highlights are, as already mentioned in the comments, a Saturday visit to MOCA (Geffen Contemporary) to see the Takashi Murakami exhibition. (Coinciding nicely with me about to embark upon reading “The Wind-Up Bird Chronicle” by the other very well known Murakami: Haruki Murakami.)

His simplest motif – which he reuses again and again in many pieces – is the smiling flowers in various colours. The 2D version of the 3D flower box is one of my favourites, and here it is in a room that is wallpapered with the motif. There’s a more solemn one with a range of expressions on the flowers’ faces in an entire field of them (“Kawaii – Vacances”) (including one shedding a tear), but I could not find a good web reproduction of it. The below is a rather small version:

It’s only the second weekend since it opened here in LA and it is hugely popular, with tons of people in the exhibit spaces walking around excitedly and pointing at things. (This being LA, this included a lot of activity in the special Louis Vuitton room, which […] Click to continue reading this post →

Coffee Thoughts

Comments Off on Coffee Thoughts

Well, it’s almost the end of the morning, I’ve just finished one set of tasks and about to move on to another and I thought I’d sit down and chat with a cup of coffee. This morning has largely been about three different outreach-type tasks. I hope to spend the entire afternoon on Physics research. I’m an optimist.

Here’s the shape of this morning:

At 7:00am I checked my email and found that an editor at a magazine was looking for something different from what I initially wrote in response to a question of hers about art and science. I’d spent some of the evening before writing something and sent it along, adding a couple of sentences at the end as a sort of final thought. Of course, she liked the last two sentences and not the rest so much (it was not getting directly at what she wanted me to speak to). So, a bit crestfallen, I tried again. In fact, I had indeed spoken to the issue, but had sort of buried it a bit. So I spent some time scraping away the unnecessary and bending and reshaping the text. Amazing how long that takes when you’ve got a word limit. I sent it along eventually. I’m not sure it is actually as good as what I wrote last night in terms of literature, but it is more to the point of what their feature is about, and so in that sense it is better. From the response I got back, it seems to be more like what they’re looking for now. I’ll tell you more about it when it appears… it’s all about a personal take on the interaction between art and science as far as inspiration goes, with a single piece to illustrate it. It’s the picking of a single piece that was the true difficulty. Took me days to decide. In the end, I had to make some hard choices indeed. I actually enjoyed thinking about the issue though. Sort of re-invigorating. I’d be happy to hear your thoughts about the matter in the comments. I’ll come back to this once the piece appears – if it does.

At 10:00am I called a television production company to talk about a new TV show for […] Click to continue reading this post →

Some of What Matters

Below I’ve reproduced the text of the approximately 20 minutes of that which I presented at the What Matters to Me and Why event on Wednesday. I mentioned my preparations for it in a previous post. The event was well attended, in an excellent setting (a hidden campus cafe I’d somehow not known about before, Ground Zero). There were students, faculty, staff, alumni, and several others. I chose to give a structured address to start so as to make sure that I did not go on for too long, as I might in a more off-the-cuff delivery. I very much wanted to leave plenty of time to interact with the audience through their observations and questions. I delivered it partly from memory and partly from reading, and wanted it to have a bit of a feel of being read a story, rather than a formal speech. I don’t know how successful that was, but it was fun for me. I think I might try that approach again some time.

Overall, I think the event worked well, and I had a great time. A number of people (kindly) said at the end that they had a good time, and I hope everyone else did too!

___________________________________________________________________________________
Hello Everyone.

First let me say that it is an honour to be here. I’d like to thank everyone concerned for inviting me to speak in this series. I imagine that everyone starts their piece by saying that they struggled to find a way of saying What Matters to them and Why in a short time. So I won’t dwell on that, except to say that it’s especially hard when, the day before preparing, you realize that it’s not going to be that hour long presentation you were expecting to squeeze your essence into, but 20 minutes!

Some time ago, when people started mentioning that they’d seen that I was a guest in this event, and that they were looking forward to hearing what I will say (!), I’d respond that I too was curious about what I was going to say, and would also try to show up and find out. This was actually true. The other thing that I (half-)joked was […] Click to continue reading this post →

New Installation

Yesterday we saw the official “installation” of Howard Gillman the new Dean of the College of Letters, Arts and Sciences. I find this term amusing in this context, as it sounds a bit like putting in a new lightbulb, or perhaps a new operating system (the latter is, I guess is closer to the truth). I sort of had to go since it represents the outcome of a lot of work I did last year on the search committee* that advised the Provost and President on their choices, and of course I have an interest in it as an ordinary faculty member of the College and of USC in general – The LAS is truly the core of USC, and we need the new Dean to do a good job of steering it forward in this (happily) continuing period USC’s steady and rapid progress on all fronts. So a good opening speech is seen as a good sign. It was good – much more than good actually – and everybody seemed to have genuinely good things to say afterwards (as we munched on the always excellent food served at these events – the other reason we go to them).

new dean installationRight: Not the most representative photo (click to enlarge), but you can see him mid-speech, with President Sample seated listening. Assembled is a lot of the faculty, mostly seated. All the other Deans from all the other units were present, as well as various vice-Presidents and so forth. They all precessed into the room, and members of USC Thornton School of Music’s choir sang the USC song, which was… quite a bit more pomp and circumstance than I was expecting. What you can’t see is that the room is about twice as big as the part you can see, there’s lots of faculty standing around in that part, with several tables of very tasty food and wine for all.

For the record, the fact that I thought that it was a good speech has nothing to do with […] Click to continue reading this post →

I’ve Got Next

Ok. So I want to make this post timely, but it means that it will begin to let a cat out of the bag. We’ll see how much I can save for a later post as I write1.

So, as I walked to the subway this morning (yes, they have one in LA), I went through my little checklist of things I take on self-assigned assignments of this sort.

Notebook for scribbling: Check
Pen for scribbling: Check
Camera: Check
Phone (now with decent back-up camera): Check
Spare battery for camera: Check
Decent excuse/reason for being spectacularly late: Check
Water: Check
Good footwear for endless walking back and forth: Check

By now you get it. I’m either doing one of my parade reports, or perhaps a street fair/party, museum exhibit, or some random science fair, object or installation or other. Yes, but which? Well, apparently I was going to the future:

That Sort of Time

Yes, it has been that sort of time. The last several days have been full of far too many things – several of which it would be fun to blog about – but none of which have left me any time for doing the actual blogging part. What sort of things? Well, everything from social gatherings like a couple of parties and salon-type events on the one hand, the usual work-type events on the other (like yesterday’s reception to welcome new USC College faculty – I find those especially important to show up to as a means of re-engaging with a cross section of one’s colleagues, old and new, at the beginning of the year*), and on a third hand (sorry) there’s been a big crunch on the research side of things. The big crunch saw me in my office until about 3:00am after a long night of finishing up two companion papers with three of my students (this included breaking for a walk across campus at about 8:30pm to get some tasty mulitas at the excellent La Taquiza) and submitting them to the arXiv. Sensibly, the students went home by 1:30 or so, leaving me the silly one to tinker some more until the end. It was a really fun couple of projects uncovering some rather rich physics, and I’ll try to tell you about them some time soon.

So anyway, my plan today was to write you a 9/11 post, but not quite about what you […] Click to continue reading this post →

Switching

Back in LA, and down at the USC campus. Good to be back! Click below for larger view.

campus overhead from google maps Well, it is the first day of the new academic year’s teaching cycle. I’m here in my office at 7:30am (the power of jet-lag) and somehow have to switch my mind back firmly onto teaching and other matters. It’s always tough to do this, since there are always lots of intensely interesting research issues that continue on my mind from the Summer, and I know that some of those will gradually begin to fade (if I am not careful) as my other duties take up so much of my day to day. My first class (part one of the upper level electromagnetism course) is at 10:00am, and I want to plan out the structure for the whole semester, and write a syllabus to hand out and discuss. As well as the first lecture, of course. I’ve not taught this part of the cycle before, and so I’ll have to be writing new lecture notes.

I want to try some new things this year. In particular, I’ve become increasingly concerned […] Click to continue reading this post →

News From The Front, VI: Simultaneity

By | | , , , ,

aspen from gondolaI stopped the previous post rather abruptly (I had to do another task and then run some errands) without getting to tell you a little twist at the end of the story. Here it is.

Having chipped away at the thoughts that Strominger’s talk stirred in my head for several days last week, scribbling equations to check that all I was thinking was on the right track (and chatting a couple of times with Nick Halmagyi), I decided that it was all fitting together so nicely that the framework and my extensions of it just had to be true. There was that feeling that it was too nice to be wrong, and it passed all the obvious checks I could think of. There were two independent consistency checks everything had to pass (using my way of formulating things) and they gave exactly the right results as required by the general setup, with no room for maneuver.

When that happens so nicely, usually at that point in thinking about a physics problem, a thought occurs to me. If I’m playing with a good idea and everything is working so well, then there’s at least 200 other people in the field who probably are also playing with it, and 199 of them have way more time than I do to think it through and write it up before I can. One should not really worry about these things in an ideal world, but I’d be lying to you if I said it did not come up as a concern from time to time. I’ve a history of having my thunder stolen out from under me several times in the field (and not always accidentally), so I’m a bit gun shy.

Anyway, I started writing a draft of the paper on Thursday the way I usually do: I write […] Click to continue reading this post →
