Hawking Talking, and More

Gosh, time flies!

I almost did not get to announce this before it was upon us. Tomorrow and the day after combine into a notable event in the College Commons series here at USC. Some of us have been working on this for quite a while. On Tuesday we have Stephen Hawking giving a big public lecture entitled “Out of a Black Hole”. Here’s the announcement. Note that general tickets for seats in Bovard Auditorium all went within hours of us releasing the tickets several weeks ago, but there is room in the two spill rooms that we have set up where there will be screens relaying the talk. Make a bit of an event of it and go with friends! [Update: I forgot to mention that we had a competition in local high schools and also at USC where the prize was to ask Stephen Hawking a question. People submitted questions over the last few weeks and we selected some of the best. There will be three undergraduates and three high school students coming up from the audience (we’ve a lot of high school students visiting us for the talk) to ask him a question each at the end. Should be fun.]

The day after, there will be a related event. Some of us from the physics department […] Click to continue reading this post

It’s Not A Superhero Movie, II

watchmen smiley

Well, strangely, I was able to walk right into the Vista (one of my favourite movie palaces) and go to my favourite seat on Friday evening to see Watchmen, without even waiting in line. So I’m able to report on this rather sooner than I thought. (Or at least I was, but Friday night saw me busy, and Saturday night I was all prepared to do so after my long hike in the rorschach costumeSan Gabriels, but I feel asleep on the sofa still in my hiking gear and did not wake up until 6:00am.) So here we are. I’m happy to report that the owner or manager guy at the Vista, who wears a costume whenever a film of this genre shows, did not disappoint. There he is on the right in his Rorschach outfit. (Click for larger view.) Quite splendid.

This film is, on the surface, partly about my people (My people? Take your pick about what you think I mean here: (a) Physicists? (b) Superheroes? (c) Physicists who like to wear capes? (d) Physicists who like to go around in the nude and are sometimes blue?) and so of course I had to go along and see and report, but more urgently I have to report because I am quite sure that most film reviewers will not be able to see past the capes and tights. Having seen a few reviews since I’ve gone, I’m not wrong so far. I get to use the above title for the post, as I did last year for The Dark Knight, because the capes and tights are a red herring.

I’ll fold the rest of this away for those who don’t want to read about the film before seeing it first, so click to read on if on the front page or on a feed.

Expensive

One of the things I am most appallingly tardy about is filing expense claims. I’m really bad about this. Not just in terms of the amount of time it takes me to get to it, but in the actual amounts that need to be claimed. People who are smart about this take less time to file their largest expenses… it is usually the opposite with me. I know people who are essentially doing their expenses as the trip they are on proceeds, and by time they’ve landed back at their home city they are putting the completed forms and bundled receipts into the mail (internal or external) with one hand while still holding their luggage in the other. I on the other hand, find myself forgetting to do it again and again, losing track of what I actually spent and can claim back, and so on and so forth as the trip fades from memory. Yes, I have forgotten to claim for entire trips, in the past, remembering years later that I was supposed to (happily that has not happened too many times). I’m not sure why this is, but it is partly as a result of the immediate re-immersion back into local life after the trip. The trip is done and now I’m back to the everyday routine. Figuring out the expenses becomes a sort of distraction from moving forward. Or it just keeps slipping my mind.

It’s pretty stupid of me, and I acknowledge it every time, but I still end up doing it. Sometimes at great cost. Right now, I have four big trips I have not claimed my […] Click to continue reading this post

Twirling, Twirling, Twirling…

Oh, yes, the midterm. Well, apparently the students don’t hate me as a result of it. (Actually I have not seen any of them since before the midterm (I was away during the actual midterm itself), so I’m not entirely sure about that…)

notebook and coffeeI stayed up until 2:00am or so on Wednesday writing and typesetting the thing, and in the end I think I set a relatively straightforward exam. Furthermore, after I finished writing it, I realized that a good chunk of the computation I’d prepared for them had already been done in a previous midterm. I’d completely forgotten. You can see a (bit blurry, sorry – in a cafe trying not too look too conspicuous taking photos) snap of my notebook with the computations that I did in preparation for the midterm in the little photo to the right.

Since Elliot asked (thanks!), I’ll say a bit more about what they had to do. I decided to […] Click to continue reading this post

Midterm One

electrodynamics midterm preparationWell, it is that time again. The first midterm exam for my electrodynamics course is scheduled for Thursday and I have to decide today what to put on it.

A key factor is that it is an open book exam. Last week I explained to the class (I have another excellent group this year) that an open book exam is in fact more challenging than a closed book one, since some of them seemed to be under the opposite impression.

The point is that since we all know that if they have the textbook and their class notes and so can look things up, I certainly can’t ask them anything that they can lift from those sources without thinking. Therefore I will be able to focus on testing their ability to think and apply the techniques that they have been (I hope) studying. This is, after all, the point of the exercise, isn’t it? More so than remembering equations, in any case. (Although one hopes that all physics students can remember Maxwell’s equations…)

The drawback to all of this is that I myself have to think harder in preparing the […] Click to continue reading this post

Bikes and the City, 2

blog on a bikeYou’ll notice that I often talk about alternatives to driving everywhere in Los Angeles. Sometimes I talk about bikes (see for example the last post) as part of a range of options. Well, in December last year a student at USC doing a project in journalism (Lauren Lee – she’s at the Annenberg School) did a short report on bikes and the city for her project. (See also some of my posts about this issue, such as here, here, here, and several posts in the list at the bottom of this one). In her research, Lauren found this blog, gave me a call, and I agreed to make a few comments to camera for her as part of her larger report on some of the changes that are happening here in Los Angeles. (She also interviews Adam and Josef Bray-Ali, owners of the Flying Pigeon LA bike shop (hey, they have a blog)- a bike that might interest you.)

I should preface it with some remarks of my own. It is a nice report, but she edited out all the things I said that I think get at a central and key point. (To be fair, she was trying to make a two minute report, and I was babbling on enough for a Spike Lee four-part documentary…) I’m not advocating that everyone cycle everywhere they need to get to. Instead, I’m trying to get across the idea that cycling works really well in combination with the public transport system that already exists. One of the reasons people give most often for not using public transport is that the bus or subway stop is not quite close enough to where they want to get to, and/or close enough to their home. Leaving aside the cases where that sometimes this means “more than one block” or “not right next to my garage”, I’m trying to get across the […] Click to continue reading this post

Some Articles

Well, as I mentioned in the last post, Sunday’s symposium at the AAAS meeting in Chicago went very well, and we successfully communicated a lot of the physics results, ideas, and excitement to the audience. One of the team, Peter Steinberg, did a blog post, and he’s also got some more pictures that you’d perhaps like to see.

Some of the journalists who were there have already produced some pieces reporting on the physics. It is actually interesting to see all their different takes on the same presentation and discussion event. So far, I’ve seen the one by Glennda Chui at Symmetry Breaking, which had the mixed blessing of being tagged by Digg (the server was down for hours as a result!), one at Physics World by Margaret Harris (this one sort of missed the key physics point a bit – see below), one at the Discovery Space Blog by Dave Mosher, and one by John Timmer at Ars Technica (He misquotes me a little here and there, but I do like the “String Theory Officially Useful” phrase in the title!). [Update: There’s also an AAAS publication here.]

Anyway, as I said, I think that the Physics Today one sort of got sidetracked a touch and so I placed a comment there to clarify some points. I realized that they might be useful to some reading here, and so I reproduce it here. Enjoy: […] Click to continue reading this post

24 – Physics Edition (Day Two)

February 14th 2009: Valentine's Day.

9:00pm – 10:00pm

…Must be here somewhere. Maybe inside the monolith? No. Seems it is not inside the jumbo suitcase, which I have not used since Aspen last year anyway, and I’m pretty sure that I did not use it on that trip. Where can it be? That box over there? No. (But I found that bag of plastic book covers that I’ve been using sparingly since I left Preston for London in 1986. Excellent. The things I don’t throw away…) Well, never mind, would be silly to make myself miss a flight over an inflatable pillow that I have not seen in over a year. If I play my cards right, I won’t need it anyway….

9:10pm Now to put all those things I set aside earlier into my trusty little day trip bag. Change of clothes, electric shaver, toothbrush and so forth. I suppose I will bring the laptop. And some bits of equipment that might be useful as backup for Peter’s plan. Or whatever. You never know. Yes, I throw in my copy of Accordion Crimes. Almost finished it, and if I do, would be good to get another Annie Proulx to continue enjoying her wonderful writing…

9:17pm Will someone tell me how I managed to be perfectly on time, and then fritter away some of it to make sure I’m slightly panicky late again? Sigh. I was more or less ready at 9:00, when I should have left. Despite all the events of the previous 24 hours ((Day One) – Valentine’s Day Diary – Available on DVD) I got everything together on time, and wouldn’t it be rich if I missed the flight?

9:23pm I leave finally, using the batcave, slowing to check that entrance closes, then vanish into the night toward the airport. Saturday night late in LA. Surely everyone is out having awkward dates? The roads will be clear this late on a Saturday night, right? I can make my 10:07 check-in cutoff, I’m sure.

9:33pm. 101 Freeway. Full of traffic. Don’t you people have dates you’re supposed to be on!!?? This is my road! My! Road! […] Click to continue reading this post
