Temperature update: Going to be 106^oF today. I think at 7:30am when I got up today it was already in the mid 80s (although that might have been partly due to reduced airflow indoors - I had to rush outside to take a deep breath). Gosh.

Above is part of a puzzle I was working on for a while on Saturday. A more detailed and larger image will follow below. I did pretty well, but then I got distracted after a while (see below). The last puzzle pieces came from (I suspect) a single puzzle piece shattering in a secondary event. The primary event? Bit embarrassing. I was preparing dinner on Thursday night, a guest was about to arrive, and a fly entered the kitchen. I hate flies in my kitchen at the best of times, and this was just too much. I tried to open the window to encourage the beast to depart, and it refused. I tried to open the window further and exasperatedly wafted my hand in its direction to scare it off the window pane, misjudged that action and pushed my hand through the window. Felt like a real idiot, of course: An expensive mistake, an awkward thing to explain, and of course a million flies and other creatures now had unrestricted access… The good news is that I only got a slight nick from the razor sharp edges, my guest did not think I was too insane (or no more than I usually am) and dinner was tasty. So all’s well that ends well.

The next morning I woke up and immediately thought “I can’t believe I put my hand through my window”. Went downstairs to check. Yes, it was true. There was a nice shatter pattern (notice the cracks radiating outward from the reconstructed impact point - see photo and discussion below) to admire, and lots of bits of glass on the Continue reading ‘Paneful Jigsaw’

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

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 Continue reading ‘Switching’

brian may receiving his phd from paul nandra For what? The story is here. Ok. Full disclosure - I was quite a Brian May fan as a teenager, and as a physicist in training while at Imperial College, London. Now I was going to do a long post about playing electric guitars, building electric guitars (because I was into electronics, physics and music, not because Brian May did it too), analyzing his guitar solos, endless listening to Queen, endless teenage arguing with anyone who would engage about why he was a much better guitarist than [pick the flashy guitarist from some other rock group], probably permanently diminishing my hearing a bit at two huge Queen concerts, and maybe best of all …practicing music with my friends in the same room (it was said) over in Beit Quad that Brian used to use for practice in the days before Queen began! That was quite a thing for me back then. Here’s a little interview with him about his Imperial College days from the IC student newspaper Felix.

There would have been pictures of the guitars and so forth, a clever post title playing Continue reading ‘Congratulations Brian May!’

This was the best I could do for a Simpsons avatar for me. (Click for larger.)

(I usually wear plain things with nothing written on them, but I suppose this particular design will do, for fun! Also, I could not really find the right hair.)

So what’s yours like? (Email me them and I’ll post them in the comments if you like. Or give a link to one on your page.)

P.S. The movie? Oh, it’s a pretty good extended Simpsons episode. I don’t know if it qualifies as a movie to see in the cinema, but then there’s an awful lot of really bad stuff out there that supposedly qualifies and can’t hold a candle to even a half hour Simpsons episode. Fun with a group out for a lark, I’d say.

Yesterday was (depending upon who’s counting) the 16th anniversary of that thing we call the World Wide Web becoming a public entity. The Web is not to be confused with the Internet, which is much older, of course¹. I’m talking about Tim Berners-Lee’s idea and implementation thereof. (I should not neglect to mention that this was done at CERN, the particle physics laboratory in Europe.) His original posting (on the newsgroup alt.hypertext) proposing the structure can be viewed here, and here’s an extract:

The project started with the philosophy that much academic information should be freely available to anyone. It aims to allow information sharing within internationally dispersed teams, and the dissemination of information by support groups.

Reader view

The WWW world consists of documents, and links. Indexes are special documents which, rather than being read, may be searched. The result of such a search is another (”virtual”) document containing links to the documents found. A simple protocol (”HTTP”) is used to allow a browser program to request a keyword search by a remote information server.

The web contains documents in many formats. Those documents which are hypertext, (real or virtual) contain links to other documents, or places within documents. All documents, whether real, virtual or indexes, look similar to the reader and are contained within the same addressing scheme.

To follow a link, a reader clicks with a mouse (or types in a number if he or she has no mouse). To search and index, a reader gives keywords (or other search criteria). These are the only operations necessary to access the entire world of data.

What am I going to do to celebrate?

letter to anon Since everyday I celebrate the WWW by using it a lot, to commemorate the event I think I’m going to pay a visit to the (real, physical) library, then read a good old-fashioned book for a while, and then hand-write a letter. I used to write so many letters, long ago, and from time to time I try to stop everything and pick up a pen and write one. I got in the mood the other day while in Aspen, and went and found some letter-writing paper and envelopes, curled up on a sofa, and wrote for a Continue reading ‘Reading, Writing, and ’Rithmetic’

Sorry about the silence. Odd thing: As a result of my (I think) growing absent-mindedness, it turned out that my flight was on Sunday night and not on Saturday night (as I thought when I did the previous post), so I suddenly had an unplanned 24 hours on my hands in Aspen.

I decided to spend the extra day lying low getting some work done - various things I thought would get undone on this trip suddenly had another chance to get done! Mostly administrative stuff. It is amazing how much one can get done when there’s a whole extra day suddenly appearing in your schedule, and so that’s what I worked on.

One thing I could have done was reminded you that the Phoenix was due to launch Saturday, and indeed it did! Be sure to check out a post about it on the Bad Astronomer with some links to really nice launch videos. The Phoenix mission plans rather wonderful things when the craft gets to Mars (including making the old reverse-thrust landing maneuver vogue again), as you can learn from their site.

Today, Monday, saw me running errands. Boring things, really. Things you do after being away from the nest for three weeks. Anyway, I’m trying to get to used to all the extra oxygen, and the unbelievable dryness. There’s still been no rain. I will miss the daily downpours and thunderstorms of Aspen. This leads me to the garden report. Nothing to say except that there’s Continue reading ‘Return to the Nest’

I 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 down the hall), 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 Continue reading ‘News From The Front, VI: Simultaneity’

News From The Front, V: Microscopic Weekend Diversions

I’ve been spending the day so far as an administrator, and not a researcher, since I have to present the results of two committees’ deliberations at one of the big annual organizational meetings tomorrow here at the Aspen Center for Physics. So I’ve been gathering and arranging data in a presentable form. Enough. I will take a break and blog a tiny bit before turning to a truly riveting task - reviewing an introductory physics textbook for a publisher… (Sigh…it is not so easy to escape these things, even out of semester time.)

I had big plans to do a hike each day on the weekend, but physics intervened. I should explain a bit more. Earlier last week I eventually got around to following Nick’s suggestion from an earlier post to take a look at Andy Strominger’s Strings 2007 talk entitled “Search for the Holographic Dual of N Heterotic Strings”. It was the usual nice Strominger talk, where he motivates the physics very well, and presents interesting and clear thoughts on the problem in hand. I shall try to say a bit more about what it is about later on, but the general gist of it is that it is to do with understanding certain types of four dimensional black hole in string theory. As you may know, one of the extraordinarily successful results in string theory in the last decade (and slightly more) has been that we can understand one of the most central results of semi-classical quantum gravity -that they have an entropy and behave like thermodynamical objects (the work of Bekenstein and of Hawking from the early 70s)- in precise terms in the full theory of quantum gravity that string theory appears to present us with. This started with the work of Strominger and Vafa in 1996, that showed how to describe a large class of black holes as essentially made of extended objects called D-branes (about which I’ve spoken at length earlier¹).

Just to fill in the gaps roughly: Hawking’s result that black holes can radiate as thermodynamical objects comes from taking Einstein’s theory of General Relativity and combining it with Quantum Mechanics in a partial way. He could not really do much better since there was no proper quantum theory of gravity at the time, but even in Continue reading ‘News From The Front, V: Microscopic Weekend Diversions’

One year ago today, I did the Welcome post on this blog. It is Asymptotia’s first birthday anniversary!

It has been a very enjoyable year of blogging here, and sharing the company of so many of you who visit occasionally or regularly to read, and perhaps share a thought, joke, an idea, or an anecdote.

This sort of blog, with its wide (and perhaps odd) selection of topics, from the fun to the serious, the trivial to the profound (well, I’m still working up to a profound post!), the light to the heavy, and the local to the global, is not to everyone’s tastes, and that suits me fine.

It has just been great to have the freedom to pick and choose topics as I please, knowing that you in turn will come and go as you please and use the scroll bar as much as you see fit. It’s an excellent arrangement.

If you have been coming back for more, then it must suit you to some extent too, so that’s great. Thanks for your readership, participation, and support. In case you’ve Continue reading ‘One!’

The Man of Tomorrow?

[Updated with a bit of video!]

Earlier this week I went for a walk with Nick Halmagyi to chat about physics, and since he had not been down to the meadows and gardens over by the neighbouring Aspen Institute , we wandered down that way. It was just after lunchtime, and a very hot day, and as we got near the Institute, we diverted away from physics so that I could tell him briefly what the significance of the Aspen Institute is. I explained that it was an important “think tank”, host to thinkers in the humanities, sciences, and diplomats, presidents, ex-presidents, and other dignitaries, who come and think great thoughts about the problems of the world. Well, let me use their own words from their website:

The Aspen Institute, founded in 1950, is an international nonprofit organization dedicated to fostering enlightened leadership and open-minded dialogue.

As an example, I explained, it is probably the sort of place that Al Gore might have come to in order to think deeply about the environmental issues he champions. It is nice that the Aspen Institute is right next to the Aspen Center for Physics, and the two organizations, while now independent (but the Center actually grew out of the Institute, see here) sometimes work together on various matters including public outreach. The public lecture I gave here last year as part of the Heinz Pagels Memorial Lecture series (see e.g. here and here), for example, was actually over in the Paepke auditorium, one of their buildings.

We approached the main grounds of the Institute, near their residence buildings, and were greeted by a most frustrating -and ironic- sight. Their sprinkler system was fully on, spraying water unnecessarily into the air and onto the asphalted walks, with some making it onto their lawns, where even there it would mostly evaporate (in addition to aiding the hot sun in scorching the grass somewhat). For once, I did not have my camera and so cannot share this horrible sight with you. For a moment it was as though I was back in LA, but this was Aspen, where everyone talks about the environment. Then I remembered - everyone talks about the environment. At the same time, there are more and more SUVs every time I come here (rental companies even try to force SUVs on you when you try to rent a regular compact car - did you read my story of that last year?), more and more land seems to be cleared to build ever-larger houses, and so forth. On the other hand, bicycle use is very high here, there’s an excellent free bus system, an enforced reduction of individual car access to the Maroon Bells wilderness area, and I imagine several other worthy environmental efforts that I have not seen are being made. So it is a tale of two communities and mind sets. It’s complicated, as with any populate. But you’d have thought the Aspen Institute would be “fostering enlightened leadership” by not watering their lawns and (sidewalks) with vast amounts of water at the maximally worst time of day to do so in terms of effectiveness. (Frankly, given the environmental disaster most lawns are, one could go further and hope that in the spirit of leadership, they’d turn more of their expanse of lawns into other use, perhaps expanding the excellent wildflower garden they have in one corner, or letting more of the surrounding meadows repopulate the grounds. It could be rather beautiful.)

Anyway, we shook our heads at the irony of the sight and we wandered off toward the river, continuing our chat about matters in other dimensions (no, really). The next day I came back at that same time to check the sprinklers again (with camera), since such systems are often on timers, but had it rained very heavily the previous night and so -happily- it did not seem that the sprinklers had been used.

On Wednesday I returned once more. The sun was overhead and strong again (not as much as Monday) and the main system was not on. But once again I noticed signs of watering, and saw a smaller component of the lawn being watered by a hose-driven system. I now think that it might be that they were sprinkling (well, gushing) on Monday (and partly on Wednesday) in the mistaken belief that pouring water (and into the air, where it rapidly evaporates) on the lawn while the sun is baking it will somehow help, and they did it on an ad hoc basis, but I can’t be sure. Either way, it is a terrible waste of water resource by an organization that is committed to leadership in matters of importance, such as the environment.

Then I noticed that many people wearing name badges were heading from the Institute toward the direction of the auditorium and the Aspen Music tent. This fit with the next deliciously ironic thing: Al Gore was going to be talking! He’d been at the Aspen Institute (I’d no idea of his presence or the event until a radio announcement on Wednesday morning), and the sprinkler matter, this was remarkable. Convenient, one might say.

It turned out that it was not taking place in the Paepke auditorium, as I thought it Continue reading ‘The Man of Tomorrow?’

It’s been one of those days. I just got back home, at 2:30am, after a very pleasant bit of work in a cafe. I was writing up my thoughts of the day into my notebook (I’m old-fashioned that way) and crafting new ones. Where was I? The 101 Coffee Shop, of course, an LA landmark - with those lovely booths, the counter, the lighting, all classics - over near the Capital Records building (another LA landmark) just where you join the 101 heading up to North Hollywood - hence the name, and hence the title of this post.

It’s been one of those days in a good sense. After a long couple of weeks of muddling and being rather down about a project I’m working on that had run into problems, things suddenly made sense today over the course of a long IM conversation (six hours) with one of my collaborators, Jeff Pennington. Things just started to fall into place during the brainstorming… we’d exchange facts and observations, explain thing to each other….muddle along for a while… ask questions… calculate separately for a bit…. suggest computations to each other…report results…get confused… and then it all broke open quite nicely and every single fact seemed to fit into place by the end. A lot to do still, but it seems rather robust and tantalizing.

No, not a metaphor. We’re really supposed to have a thunderstorm today. High probability they say. It’ll go up to the 80s and 90s again first, and then it’ll crack open…I hope. I’ve not seen rain for so long I’ve forgotten what it is like. Please let’s have some rain. We’ve seen three inches here in the last year (about 12 short of what it should be), and boy do we need it… (Apparently it’s all over in Europe. There are floods, I hear.)

So I sit here, trying to calculate, while hoping for rain - and a real grand-piano-falling-down-the-stairs thunderstorm!

. 4 Comments

Yesterday afternoon, feeling a bit down in the dumps for a variety of reasons, I decided to head for the hills to clear my head. A good hike often helps these things. My other mission was to begin the painful task of breaking in some new boots. The fantastic repair job that I got done on my faithful old boots that died last year (see here for the full report) held up marvelously, and in fact still holds up, but I will admit that they lost a fair bit of flexibility with the new sole, and although they are great for the medium grade sorts of hikes I do in the immediate surroundings, I’m not really sure that they’d be great on the longer ones. I have not taken them up Mount Wilson, for example. The repair extended their life for quite a bit longer, and they will still be useful, but I decided last week that I should start breaking in a new pair to last me (I hope) another 15 years or so. I decided to try to get something as close to the ones I had as before, and so the Asolo TPS 535s were the ones I got (supposedly the natural successors to my Asolo AFX 530s). So I laced them up (already unhappy with the wimpy laces they have as compared to the big rope-like ones on my old boots) and set off from the trailhead in Topanga.

My goal? Eagle Rock. A favourite of mine. There it is in the photo on the right (click for larger). It’s a relatively quick hike, about 3 miles out, along the Musch trail (not the fire road) and a 1000 foot elevation gain, with mostly nobody around since it is insanely hot at 2:30pm and only mad dogs and Englishmen (so the Noel Coward song goes) go out in the midday sun. I’ll leave you to decide which I am (remember, on the internet, nobody knows you’re a dog). So I was able to speed up the mountain to the Rock and stay there for a while, only meeting four other people heading that way the whole time.

You might wonder why it is called Eagle Rock. I did for a long time, as probably have Continue reading ‘Boot Camp’

I forgot to post this yesterday, when it was more relevant, but here I go anyway. I’m not looking to offend anyone here, I’m just curious, and have been puzzled about this for years. I’m reminded of it every year at about this time. What am I talking about? Wimbledon.

Not the event itself (which I have not followed in over a decade or so) but the word, or rather its pronunciation. I’ve noticed that a lot of people in America - from people I encounter day to day to newscasters on NPR - seem to get very confused about the “d” and pronounce it as a “t”. So you get people talking about the “Wimbleton” final a lot at this time of year, especially when someone from the US is in it (see photo at right [credit: AP Photo/Andrew Parsons, PA]). Has anyone else noticed this, or is it just my hearing? (Or worse, perhaps it is pronounced with a “t” and I’ve just not been paying attention all these years, and somehow I just hear it more clearly over here when some people say it.)

I’ve been wondering why this happens. Here’s some additional data, I’ve painstakingly Continue reading ‘Teesandees’

Mingus Lives!

Just now I noticed to my horror that it was on the 1st of September of last year that I intended to get around to repairing Mingus, my G4 powerbook , at the time the main workhorse of my away-from-campus computer arsenal. There was an unexpected failure which I could not figure out the source of, and I managed to get it partly alive -alive enough to drag about 12 GB of data from the hard drive via booting it as a target disc of an iMac, Ella. Well, I never sent it off as I was (1) thrown by the fact that I had no warranty or repair contract coverage on it, and so any repair would have to be paid for, and (2) in the middle of the semester - a really busy one - and so I did not really have that much time to devote to the issue.

Well, it all got put on a back burner because I decided to use my teaching laptop (a little iBook) as my main laptop -just for a week or two, I told myself. Eventually, last Continue reading ‘Memorising Mingus’

Consider a Spherical…

So I went out to get a new kettle a few days ago. I’ve now given up on a rather lovely design by the company Chantal that I’ve been using for many years since on two models in succession (or is it three?) the same flaw has revealed itself - the plastic parts of the Hohner whistling lid began to loosen gradually (probably from too much heat up the sides, which may be my fault) and then you eventually end up with a non-fitting non-whistling lid.

I began to assess other kettle designs, and in doing so found myself thinking idly about a number of physics issues. One of the main ones was energy. If I got a smaller kettle (the one I had before had a capacity of 1.8 quarts, and I was considering ones as big as 2 quarts and ones as small as 1.5 quarts), which I was leaning heavily toward, it would probably encourage me to save energy and not boil so much water. On the other hand, maybe that’s really silly, since I might just be putting the same amount of water into the kettle anyway… I’d never fill either up all the way in any case. But if I put the same amount of water into both kettles, would the smaller one end up using less energy anyway as I don’t have to heat up the extra air in the chamber, or does that not matter…? It’s not that simple since the chamber is not sealed. Hot air (and later, steam) is escaping all the time. Well, this is all complicated by the fact that the smaller kettle has less of its base in contact with flame, so I’d have to turn down the flame, and heat it for longer on a lower flame than with the larger kettle… would that make a difference? Perhaps a smaller chamber at lower flame means slower steam escape velocity, and so a quieter whistle. Not good if you’re prone to forgetting that you’ve put the kettle on during an absorbing computation…downright dangerous, in fact!

This was not an entirely serious discussion, you see, but it’s sort of fun sometimes to find these things floating around in one’s head. Physicists (and I imagine, other scientists) have this sort of thing flit through their heads a lot. The key thing -especially as a Theoretical Physicist- is knowing when to engage with one of these problems, and when to ignore them. Is there are clear route to tackling the problem? Is it worth it? Is there something to be learned from solving this problem that might be useful elsewhere? In fact, I was trying to explain this all to a writer friend of mine Continue reading ‘Consider a Spherical…’

morning computations …and then you have days when nothing works. At all. This was not like last Saturday. Despite starting out nice and early with a cup of tea in the sunshine and scribbling away while wrinkling one’s brow. Things got worse and worse through the morning, as I realized that many things I so wanted to be right about the next stage of my computation (which perhaps I’ll tell you about one day) were in fact not going to work. Not even close.

By lunchtime I’d given up, and summarized my thoughts on the research blog for my collaborators. Was probably not the most encouraging reading for them to encounter, but I tried to be as constructive in my deconstruction of our idea as I could. I’m hoping that they -or later, I- might find some useful threads to pick up on from my notes and remarks.

It’s not over yet.

Maybe I should have gone for that hike instead of sitting entirely at home on a Continue reading ‘Morning Computations’

The Two-Body Problem

. 11 Comments

Ah, the two-body problem. On NPR’s Marketplace last week, Kai Ryssdal had a piece entitled “Studying ways to help 2-career couples”, covering a “Dual Careers Conference” at Cornell. The audio is here, along with a transcript.

It’s an important issue, (which I’m not going to spend a huge amount of time on here, since I’ve been blogging too much this morning so far), and I’d no idea that there were conferences devoted to it.

From the point of view of academia, there’s one aspect of it which still has not penetrated very far in the minds of many, in my mind. It is one I tried to emphasize when this issue came up during various advisory committees I’ve served on with relevance to matters of hiring, diversity, etc. What’s on my mind is that the two-body problem (as it is jokingly referred to by some) is not always to be thought of as a “problem” from the point of view of potential employers. In fact, if you can work with a potential employee to find employment for their spouse at your or a neighbouring institution, it actually can strengthen your faculty roster in many ways. Aside from the obvious ones, there are the benefits of having happier employees who are committed to setting down roots, rather than an employee who is spending a lot of time travelling to or calling their spouse in another city, wondering every day whether their job is really worth that strain. Retention is a huge issue in managing your faculty. The value of settled employees cannot be overstated if you take the long view for your organization.

Anyway, have a listen to the article (or read the transcript). There’s the usual interview with members of couples who are academics and struggling with the issue, and it’s interesting if you’re not familiar with the matter, or perhaps if you’re in academia, early in your career and wondering about what the job market holds for you. And if you’re currently wondering whether to date other academics or not, don’t be put off (at least not by this issue!). Things are getting better. Employers are getting smarter Continue reading ‘The Two-Body Problem’

notebook working Yes, part of my job is to sit and think about how the universe works. People hear this, and they wonder exactly what that entails. Well, it entails a lot of things - sometimes there’s the grand thoughts and the thought experiments and the like that you hear of from documentaries and books about Einstein and other famous scientists - but more often that not it is grungy nuts and bolts.

Take yesterday for example. After a week of working on various calculations and chipping away at improving my understanding of how to approach a certain problem, I decided to take Saturday and be outdoors a bit more…see what it was like outside. You know…. Have an actual Saturday Saturday. (I did not end up being booked to do that TV shoot, by the way, so I had a nice clear day ahead of me.)

Trying to calculate all day long. Lunch break. During this moment of procrastination, I thought I’d tell you about the product of yesterday’s procrastination. At some point in the morning I decided that I was not thinking straight about aspects of my computation (like what it all means), and that this could be helped by having a bigger space to work on that I have at home right now.

I don’t know about others, but sometimes in addition to the need to change venues during research thoughts, I also need to change the medium I’m writing on. So at lunch I went shopping and after visiting far too many stores (art supply for one part, office supply for another) to get the right things, look what I got (see left picture)!

Remote Thoughts

While coming into work today just before lunchtime, I carried with me one of those little remote controls for today’s seminar speaker to use to click through his computer slides (I highly recommend such a remote, by the way, as they completely free you from having to stand next to the computer, often resulting in a better presentation for all concerned).

Thinking idle off-beat thoughts as I sometimes do, I couldn’t resist pointing and experimentally pressing the button a few times. What was I thinking? Well, it would have been nice to:

remote 1

STOP the 11:55am bus I just missed, and used the BACK button to bring it back to the stop so I could get on it. This would have been useful since (a) I would have made it to the seminar at the right time, and (b) I’m sure I would have sat next to and talked to that fascinating and beautiful woman I’m supposed to meet on some sort of public transport some day. She must be on that one I just missed since she sure as hell is never on the bus I manage to catch! (Wait… maybe I had my one shot at that and blew it already. I remember now…)
STOP that toddler over there from enthusiastically licking the hand rail (I got a bus 9 minutes later) while his mother is not looking! I’m all for kids interacting a bit with the world to auto-immunize, but this seems a bit of an overdose.
STOP not just my watch, but all time just for about 9 minutes in order to catch up and make the seminar.

Well, none of that happened (you’re probably not surprised to learn), and the remote stayed in my bag for most of the rest of the journey….

A bit later I realized why the button would not work!

(The striking central red piece above is by the artist called Alonys (as are the ones surrounding). You can see more things of hers at her myspace space.)

Well, it’s been a busy week here, and I had tons of things to tell you in about five or six extra posts (beyond the quick ones I did) that never made an appearance. I had several for last weekend too. I ought to start by catching up from there. Here goes a bit of recollection and reflection:

Saturday was interesting since I ended up cramming three different activities into the evening, after a day of gardening and errands (mostly the latter), if I recall correctly.

The evening began (as it did the Saturday before) with a trip to an opening at an art gallery. This time it was downtown, near Gallery Row, (it is called Crewest) and it was featuring the work of some up and coming female artists. Overall, I was not overwhelmed with things I thought were great, but the exhibition was not without some interesting pieces on the walls (see above - some of her 3D sculpture-meets-painting works were fun too) and sometimes interesting people milling around. There was even a DJ, but sadly no wine (I’d been spoiled by the last gallery reception, I suppose.)

Well, it’s Friday, and the end of the week of standard work days, although not of course the end of the working week. I’m sure I do not speak only for myself when I say that this job does not really get switched off at a specific time every day (as you’ve seen), and it certainly is not contained to any specific days of the week. But I do scale things back quite a bit on Saturdays and Sundays and try to focus more on other things in my life (there are exceptional circumstances, of course). So this will be the last in this short series of “day in the life” posts describing my work day. (The last one was here. You can find all the others listed at the bottom.)

8:30am Finally I managed to get a lie-in! Unfortunately this is probably due to poor sleeping due to the fact that I accidentally fell asleep with the radio on (with no sleep function set) and so my entire night was full of the BBC and NPR. Getting ready this morning I realize that every story on NPR is familiar because I probably heard it at 4:00am already. I have poor reception in my bedroom, and so I listen to the radio over the web on a computer. It did not go to sleep, since the radio streaming keeps it active. If I want to fall asleep listening to something, I usually overcome this shortcoming by listening to a podcast, but this time I did not get to starting it before I dozed off. Anyway, tea, cornmeal porridge, coffee. No shirt ironing as I don’t need to be terribly professorial-looking today, much (see below).

I’ll be in semi-stealth mode again today (like Wednesday), in order to focus on research matters, but only semi. Again, I’ve avoided scheduling any meetings today (except one - see below). Although I do not leave for work, I settle down to dealing with various administrative matters. This starts with emails about next week’s colloquium, a future colloquium, and things of that nature. Also check blog, and add entries and begin to clean up the post about yesterday for later appearance.
10:00am - 12:00pm Basically a mixture of reading some more research papers, some more email exchanges about next week’s colloquium, and reading the research blog in preparation for the meeting with the team later today.
12:15pm. A bit panicked again since I do not have any idea how it got so late! Need to shower, dress, make a sandwich, pack my bag and get to campus by 1:00pm. And it normally takes me 45 minutes if I’m lucky with the buses.
12:30pm. Now leaving home. Decided that the bus is not the way to go in view Continue reading ‘End Notes’

Continuing the week, here’s Thursday:

6:45am Look out the window toward the sun. Another lovely day seems to be starting, at least with regards the weather. Next hour and a half is spent on similar things to the last three days. Go back and look at the earlier posts (listed at bottom). Except cinnamon-raisin bagel with cream cheese and cherry jam instead of oatmeal, in case you were wondering.
8:15am Not quite ready (shower time warp -see earlier- and other things delayed me), but have 9:00am meeting and should have left by now. Should *just* be able to make it if I’m lucky with the bus, but send quick email to tell the person I’m meeting with I might be ten minutes late.
8:32am I made the bus after all. Saw that other faculty member who rides to the bus stop as I passed her on my way and waved. She made a sort of “Nih!” noise of either recognition or surprise or both. I even took a gamble on the bus and jumped off bike, got newspaper from vending machine (thereby missing a cycle of the lights) and got back into the traffic. Always good to have a bit of derring-do in the morning.

I really only get the LA Times on Thursdays, with any regularity. Mostly because I like the Weekend section, which has listings of events coming up, and some interesting feature article or two about some LA thing or person or other. They’ve been interesting to me more often than not, on balance. Not always hugely interesting, but enough for a good 25 minutes read on the bus. The Home section can be good too. So I get it just in case there’s something good. Indeed, it pays off, and there are some good things. I’ll point two of them out in some later blog posts, I hope.
9:00am Meet with a bright and enthusiastic student who wants to do a Continue reading ‘Thursday Notes’

Notes from Stealth Mode

Continuing, here’s a short notebook on Wednesday.

6:45am A tad annoying that I woke up at this time. I deliberately did not set the alarm so that I could have a bit of a lie-in. Of course, my system woke me up at the usual time anyway. Similar morning ritual to last two times (yes, oatmeal again since I’ve run out of cinnamon-raisin bagels), but no shirt-ironing was involved. I’ve decided to be in stealth mode for most of the day, which means stay entirely away from the campus and work at home.
8:15am Decide to first tinker a bit with the Tuesday diary post. Turns into a bit more of an epic than I intended. Tinker with it and catch up on email for an hour or so.
9:30am Start reading one of the papers I planned to read today. It’s an excellent one from the early 90s by Greg Moore. I’d never appreciated it back Continue reading ‘Notes from Stealth Mode’

Continuing, this was the Tuesday:

6:45am… Get up and look outside. Huh. Super clear and sunny. Unexpected, after yesterday. Cup of tea. Check email (delete 30 spams). Look at blog. Slow steady getting ready ritual while listening to NPR: Oatmeal again today, coffee for bike bag and journey in, sandwich for lunch…ironing a shirt…
7:50am Have five-minute shower.
8:05am Get out of shower. Aarrrrrgh! This is one the great mysteries we must solve concerning time, space, life, the universe. There’s nothing in Einstein’s GR about this: Why, when you go into a shower and spend five minutes - in your frame of reference - has 15 or 20 minutes passed by in the outside world?!
8:17am Having gone from leisurely pace to frantic (since I have a 9:00am meeting) I leave home muttering something like “show me the meaning of haste” to the B as I point it toward the bus stop. (As usual, I make a mental note to not turn the haste into a misstep, so I go along my cycle route with purpose, but not abandon. I should make the bus that leaves about 8:27 or so.
8:32am I did. On the bus I plan a future lecture for the string theory course about the role of various dualities in understanding strings. This is from both an historical and physical perspective. The history is interesting, but I’m also keen to present various physics perspectives to give a clear platform to help the younglings see further than what has been seen before. Yes. I said younglings. I know, it was deliberate, because it just sounds so silly.
9:00am Technically this is on the the office hours for the E&M course, but nobody every shows up since (a) It is not the day when, or day before a Continue reading ‘Not all Noteworthy’

Married to the Physics?

Well, it starts out:

When physicists marry physicists, the beginning may be a ‘big bang,’ but issues of life, love, and family gravitate toward the universal.

Ok. Stop there. That’s way too many physics puns and double entendre in one sentence. It’s a nice article by Mike Perricone in Symmetry magazine about physics couples. Physicists who marry physicists.

Physics, families, careers, children… it’s all in there. Have a read.

Best of all, perhaps, there’s this wedding cake to the left, which is just - Wow! (Click for larger view. More in the article itself.) I wonder what my mum will think of this? She makes cakes - wonderful ones, and can decorate them with flowers and leaves made of sugar. But I’m pretty sure that she has not tried equations of any sort.

Notes From the Day

The other day (some weeks ago now) I started a sort of “day in the life” post, to give you more of an idea of what a typical day was like at work (and maybe also a bit at play). Somehow I never finished it, and then I looked at it a while later and could not remember the rest of the day, and so just deleted it.

I’ve decided to do something different. There really is no typical day. So I will try to do a series of days instead. Of course, I’m not going to have tine to sit and do a long, detailed entry about these days, and so instead I’ll just do a sort of sketchy notebook, with some time stamps. From time to time during the day I’ll stop in and add to it, and then post the whole thing at the end of the day before going to sleep. I won’t include all details (I’ll spare you bathroom breaks, personal grooming, and things of that nature, you’ll be pleased to know), but will try to give you some impressions of how the day goes. If people are interested (and people did ask for such a “day in the life post” before), I might try to do them more frequently. But for now, I’ll try and do one for each day of this week. Average over them to get the typical day.

So here goes.

Well, this work week really started on Sunday night.

11:15 - 11:48 pm (Sun): Thinking about structure of E&M course. When to set the next midterm (we agreed that the previously announced date was too soon). Also thought about what homeworks to set for the last part of electromagnetic waves in dispersive media, and though wave guides. Sent email to whole class about this.
12:30am (Monday) After reading a random entry or two at the ever-brilliant Girls Are Pretty blog (e.g. here), I fall asleep listening to podcast of the BBC’s wonderful Broadcasting House (radio 4). I still miss the excellent Eddie Mair, but this new guy seems pretty good.
7:15am (Monday) (Later rising today since it is Monday and I don’t have any early appointments and I try to get a good night’s sleep when I can.) Over cup of tea, read email. Delete about 30 spam messages that have arrived overnight. I note the kind letter from Dean X at institution Y acknowledging receipt of the long detailed letter in support of a promotion for candidate Z, and thanking me. Good that he/she did that. Took a good chunk of Friday and Sunday afternoon to write that epic.
7:45am Not in a rush to go in yet, I have a longer breakfast - cooked some Continue reading ‘Notes From the Day’

I think I ought to explain, as promised, why I am in New York. The first thing to mention is that I wrote the previous post in this miniseries (it was written on a flight to Dublin, and finally posted when I returned) before I knew about any of what I’m about to tell you, so it is rather funny to me…

The week that I returned from Dublin I noticed a phone message from an editor of a magazine asking me to return their call. A couple of days later I learned what it was about. It’s a magazine that largely focuses on buzz about people and projects in the entertainment and fashion industry - Music (R&B, Hip Hop mostly), Movies and TV, etc., as far as I can tell, along with some coverage of parts of the business world. Its readership is mostly younger African American males, I think. As far as I can tell, the intention is not to be about those things in particular, but it is largely reflecting the interests of the readership it is targeted at. It’s a major product, jumping out at you immediately when you are in the magazine store (the striking picture of a woman on the front helps it grab your attention, of course).

Each year, the magazine does a special issue featuring a group of individuals who are doing “major things” in the industries I mentioned above. It is a combination of a focus on new talent that’s about to become more widely known, or just bringing to readers’ attention the existence of some of the people who are making significant impact in what they’re doing.

Somehow - I do not know how - they got my name. It turns out that they spent some time reading some of things I’ve written here at Asymptotia too. Now normally, you’d expect things to stop at that point, but in fact it did not. They decided to broaden things out a bit and include me (if I was willing) in this year’s feature issue.

I thought about it for a day. It is quite an honour to be approached, and I’m also impressed that the magazine’s editors are being creative in this way (it would be easy Continue reading ‘When Worlds Collide, II’

Well, ok, it is working well out in the field. (See here for what I’m talking about.)

Keys started out a little sticky, but are loosening up with use. Good. Ok, here’s a secret: I admit to feeling a little (just a little) smug among the group of people sitting here, ‘cos you see they’re all the same - all five of them, in one tiny cafe - with their normally individual and cool-looking macbooks (it’s one of those ‘hoods), now looking unneccessarily big, heavy and clunky in comparison.

Ok, I’ll stop being annoying. It was just a smug moment, and now it has passed. Here’s the setup in the field:

Lots of shopping today. Among the places I went to was Fry’s Electronics. The particular one I went to is always fun since it has an aliens theme. They don’t do the theme in a subtle way…. it is all over the shop…. it starts with the big alien spaceship that has crashed into the front:

…and all through the shop there are little aliens in the rafters, and on the ground you have members of the military shooting up at them….it is the middle of a big battle you see (the military jeep has been cut in half by a ray gun of some sort - was not able to get pictures without risking my place in the 45 minute-long (!) checkout line….).

I go to Fry’s Electonics for actual electronic components. It is in fact quite good for that sort of thing, and is a welcome break from the Radio Shacks of this world, which used Continue reading ‘Sunday at the Shops’

illustration by Deanna Staffo Well, it is midnight and I am only on page 12 of the notes I am writing to present as a talk in the Southern California String Seminar tomorrow at 9:15am. Don’t try this at home - prepare talks early, ok?

Where is the seminar being held? UCLA! What University am I from? USC! What event happens tomorrow besides my (hopefully not too terrible) talk? The big USC vs UCLA head to head in College Football. If USC wins, they go to the championship game, apparently. Yay.

So the usual articles about the cross town rivalry between the two institutions have shown up this week in print and on National radio and TV. There are two amusing (and interesting) ones that I looked at - one in LA Weekly (about academic performance, faculty recruitment, student acheivement, and much more - illustration above from it, by Deanna Staffo), and one in the LA Times (mostly about nightlife). Have a look. There are dozens of others -just type USC into the LA Times search engine for example. You learn things about both universities as well from those two, so it is not without some point. For example, our young ones clearly go to cooler bars, for a start, as you can see from the pictures in the LA Times article.

(Strange that the articles do not mention the cooperation and general fun had when their high energy physics groups get together to discuss topics in string theory and other physics. Very odd omission indeed.)

I would say a lot more about the articles, but time is not on my side, so I will instead leave you with a blog post I wrote (“Drag the Bear”) on December 2nd last year, upon encountering something strange on campus:
