Recovery and Jumping Back in

So that was by far the most ill I’ve been in many years. The flu wore on for five days, with two and a half of them having me mostly in delirium, fighting highs and lows of fevers… quite remarkable. Then I had two extra days of eating very little, so that by time I started eating real food again on Saturday, and going outside, it was as though the world had been made anew to see and taste various things I’d not had in a while…

Ok… I suppose this means maybe next flu season I’ll finally start taking flu shots? We’ll see.

Anyway, I am reasonably sure that I caught that virus while passing through Atlanta airport on my way back from New Orleans. There, so many paths cross as it is a major hub. Spending two hours there gave me ample time to pick something up. Then there’s the plane as well, with four hours to sit in one space in contact with the things a possibly infected traveller before me had contact with. Nice.

I’ve been much better for a few days now, and semester has got going here. I’ve given Click to continue reading this post →

Music Matters

(Photo: Taken during the break in the back room at Howlin’ Wolf in New Orleans. The Hot 8 were playing late into the night – super loud and energetic in the tiny space – and it was great. A really classic New Orleans sound.)

Having returned from the (excellent) New Orleans trip (lots of food, lots of music), I started to turn my attention to things like the final preparations for the Science Film Competition – the submissions are due Monday and the showcase is on the 23rd – and preparations for the lecture course on Electromagnetism I’ll be giving, starting Monday. But then I got hit by a virus, and yesterday was lost to the violent swings between freezing cold and boiling hot that accompanies an intense shivering fever. Click to continue reading this post →

I’m in New Orleans for a few days. Exciting, as I’ve never been here before, but it has been on my list of cities to visit for a long time…

I thought I’d share with you the above photo of an important (to me) artifact that I visited in the old US Mint building, which has a number of exhibits. This is the cornet that, as a boy, Louis Armstrong leaned to play trumpet on!

This is sort of a big deal for me. It would be like finding a set of notebooks that the young Click to continue reading this post →

Interview with TAEM

I was interviewed by an online publication called The Arts and Entertainment Magazine for their 1st January edition. You might find it interesting, since I talk about some of the themes I bring up here a lot, such as trying to improve public understanding of science, and various projects connected to that sort of thing. It is here. Enjoy!

Actually, they’ve started doing a series of spotlights on various scientists, so browse through the website for other interviews, if that interests you.

Happy New Year!

Happy New Year! I wish you all the best for the New Year. If I’m lucky enough to have one half as good as last year, I’ll be a very lucky man indeed.

The photo shows the cufflinks I wore last night to a very special celebration that I co-organized and co-hosted for New Year’s Eve. It was a private party and the Los Angeles Natural History Museum was the venue. We were honored to get to do the first ever New Year’s Eve celebration there! With the help of some friends (and three months of planning) we were able to turn the Hall of North American Mammals into a great party space, (with the appropriate security and so forth needed to use such a space for a safe private function), and celebrate in a sort of art-meets-science environment. Music (live and recorded), food, drink, dancing, and general merriment prevailed until the wee hours, and then we went off into the night on the Expo line. It was an excellent evening.

A great start to the year…

Now, about the cufflinks. I love them. They’re made with vintage watch movements, and you can see some of the rubies Click to continue reading this post →

Critter Battles

I seem to be having a bit of friction with Nature right now. Need to sort this out. Monday, waking up in the desert (family visit – staying in a house not a tent), I put my hand on my pants to put them on and go out into the world. There was a strikingly sharp and hard jab, as though I’d grabbed a needle with my finger. I thought it odd, not having had a needle or other pointed object in my clothing. I decided to have a look… There, partly visible in one of the pockets was a scorpion! I thought about this for a few seconds and tried to recall whether there was some kind of venomous variety in this area, and whether this was one of them. Pausing for a while, I felt slightly dizzy for a tiny moment and then decided that was my imagination, and then I carried the pants out to the kitchen to discuss the matter with one of my hosts. After some research (and his rapid dispatching of the unfortunate beast), I decided that it was the wrong sort, and moreover, at only a few inches in length, probably too juvenile. Also, my finger showed no signs of distress, and so I got on with the day.

Last night, back home in Los Angeles, I discovered an unwelcome visitor in my crawl Click to continue reading this post →

I hope you’re having a really great and peaceful holiday time, whatever tradition you use to celebrate the season. I’ve been rather taken up with a number of things, including a bit of family travel, and family visits, which meant that I lost some blogging days. Sorry about the quiet.

Is anyone else hoping that (when they release it in the future on DVD/Blueray) the director’s cut of Peter Jackson’s “The Hobbit” will actually be 40 minutes shorter than what’s out in cinemas now?

Taste

…of Mexico. It was an excellent evening again this year (November 30th, actually). This was the second one (the first was in 2010) and I think the idea is to try to make it an annual event. It is in that great space downtown, Vibiana, the former Cathedral of St. Vibiana (now de-frocked, I suppose).

Anyway, the fellow (photograph right) making something (whatever it was) using liquid nitrogen caught my scientist’s eye (I usually carry a couple with me when I go out). It reminded me of the ice-cream people used to make at various departmental parties in physics departments in my past. (Always seemed like a good idea for novelty, but I never ate any of the ice-cream. I think I’m a fan of making things like that the slow way, letting the flavours settle in…) I wondered what he was making, but did not wait to find out since I was not on my own and a crowd immediately formed around him.

What happened a short time later was a bit unexpected. I enjoyed listening Click to continue reading this post →

They Seemed to Like It

What? The final exam I set on Friday. I spent a lot of time trying to get this final exam right. The problem is that I tend to decide at some point that I want to set an “interesting” exam, and then this usually ends up being more work for me than for the students, since I not only have to think of the questions and make them the right level of difficulty (made harder by being open book and, in this case, a take home -well, take to where ever for 4 hours), but then endlessly debug to see that it has no mistakes (since I won’t be present to answer questions). This time, I spent a lot of time on units, since I wanted to set an exam that kept all the factors of c and mu and epsilon present in all the relativistic notation and right down to the final unpacked Maxwell equations and all the quantities they computed in various examples. I decided to have them explore a little non-linear electrodynamics, since everything they’d seen was mostly linear. You start with the familiar (Maxwell) form of the equations:

[tex]
\nabla\times\mathbf{E}=-\frac{\partial\mathbf{B}}{\partial t}\ , \qquad \nabla\cdot\mathbf{B}=0\ , \\
\nabla\cdot \mathbf{D}=\rho\ , \qquad \nabla\times\mathbf{H}=\mathbf{J}+\frac{\partial \mathbf{D}}{\partial t}\ ,
[/tex]

where [tex]\mathbf{D}[/tex] and [tex]\mathbf{H}[/tex] are related to [tex]\mathbf{E}[/tex] and [tex]\mathbf{B}[/tex] using the “constitutive equations”: Click to continue reading this post →

Local Connections

Well, Thursday’s meeting was a blast! I had decided not to try to get people to RSVP for the meeting this time, and so when it came down to the day before, I had no idea how many were going to show up. This meant that I had to make some guesses about how much coffee and tea and cookies to organize, which was a little bit of a challenge. But just before 9:00am people began to show up, and kept showing up, and by time I was ready to start off the day’s meeting, there was a really good crowd!

In the end it was a great day, with five really good talks and lots of excellent discussion. Click to continue reading this post →

Premiering…!

You might remember that during the Spring and early Summer I was deeply embroiled in making a film. (See several earlier posts, e.g. here, here, here, and here).) It was a short film to celebrate the 50 year anniversary of the Aspen Center for Physics, and I was keen (in my role as filmmaker) to give it a treatment that benefits from my being a theoretical physicist, and one who is familiar enough with the Center, all in order to get the right tone of the film. (Jump to the end of the post if you want to see it without more background thoughts.) There’s a spirit of the Center that is quiet, reflective, and inspiring of thoughts that need time to be explored, so I definitely did not want the usual loud, buzzing, overly busy type of film that you often see about science activity. It did not seem appropriate. Working with Dave Gaw (who was an awesome principal cinematographer and editor for the project) and with Bob Melisso (who shared some of the production and direction work with me), I think the result strikes the right note overall. A fun side note: I got to design a number of unique (and definitely handcrafted) elements for the look that I think you’ll like and recognize from other visual work of mine you’ve seen on this blog, and just as with my earlier film projects from 2009 (see here and here) it was a real buzz to help figure out how to make them fly, and then see the elements come together in their final form up on screen.

People really seemed to like the film a lot, from what I’ve heard. (It was shown extensively at many of the Summer events celebrating the 50th at the Center.) So while it did take a lot of my time, it seems like it was time well worth spending since Click to continue reading this post →

Southern California String Seminar May 2011 in progressThe next Southern California Strings Seminar is on Thursday 13th December! I’ve now made the website for this one and it is here. Come back to it from time to time to see the updates of talk titles as speakers let me know what they are. It is a one-day event filled with five talks and plenty of time for discussion. I’ve snagged a lovely room in the Doheny library again. (Photo left has a shot of the room we used last time it was at USC in May 2011. The most recent one was over at UCLA.)

You are welcome to come and do physics with us! Also, if you’re part of a group in Click to continue reading this post →

Slow

Sort of stuck this morning. I was up at 6:30am (more or less my usual time these days) with good intentions to get back to do a nice stretch of work on The Project for the first time in a while. But it is almost 10:30am and I’ve done nothing (not counting procrastinating, making fruit compote for pancake breakfast, sending a bunch of emails, and so forth).

It is difficult sometimes to reboot back onto task on a project when one is suddenly done with one of the major things pulling you away from it. Classes are over, you see, and so I am transitioning into a different mode, and not super-efficiently.

I think maybe before I have to leave to run errands out in the world (after lunch), I must get something done toward Click to continue reading this post →
