Fair Play

Yesterday saw my annual stint of judging at the California State Science Fair. Somehow it managed to sneak up on me this year, and so I did not get to do what I planned to do, which is encourage one or two scientist/engineer friends of mine in the area to sign up to get involved, since it is such fun and quite rewarding (ahem: Michelle P., Amy M., mark your calendars for next year! I’m going to come a-calling…) See earlier posts (e.g., here, here) for science fair descriptions, and the fair’s own site with lots of photos each year is here.

(Ok, there’s the whole getting up in time to arrive there by 7:00am or so. That bit is less than good, perhaps.) I arrived a bit later than 7:00, due to some breakfast procrastination that science_center_parkingI somehow sometimes manage to do even when I wake up with plenty of time (a whole hour this time) to get ready. My plan to simply set out by 6:10am and pleasantly walk/bike and bus down (my usual mode) was thwarted by this and so I had to take a somewhat quicker mode of transport, launching out of the batcave in a hurry at 6:50am! By 7:15am the parents and students in their SUVs and minivans were arriving at the California Science Center in droves, and so this meant that parking was a bit more of a challenge that it would have been 15 minutes earlier. But as you can perhaps see on the right (click for larger view), it all worked out in the end… ( 🙂 )

Here’s a shot of the annual morning briefing of the volunteer judges (all well fed, […] Click to continue reading this post →

Herschel & Planck Ariane 5 ECA V188 Launch CampaignTomorrow is the Big Day. For what? The launch of Planck and Herschel – Major new windows on our universe. Keep your fingers crossed for luck!

They’re on the launch pad right now. See here.

So, what are the missions and objectives of these fine spacecraft, I hear you ask.

Well, from the Planck site: […] Click to continue reading this post →

Professors Do It Too

Remember a couple of weeks ago I was mentioning an outbreak of schoolboy(-like) giggles from my physics 408b class due (it turns out, if you did the homework on the equation) to some audience-perceived off-colour hidden joke in some of the material I was presenting? (I’m still a bit embarrassed since I had no intention of making the joke they saw.) Well, just a couple of days later, I was witness to it again, but this time it was in a lecture by someone else, and the audience was mostly professors, and it was one of my esteemed colleagues who couldn’t help himself and broke out giggling. Well, actually, there was a short loud guffaw which burst out. So you see, even the fine upstanding citizens can submit to juvenile giggles.

Let me tell the story. We had the eminent evolutionary biologist Patricia Gowaty (UCLA) give an excellent talk entitled “Darwin and Gender”, as part of the College […] Click to continue reading this post →

Unintended Giggles

Quick question:

So, has anyone else, while teaching a class, heard a breakout of schoolboy giggles behind them upon sketching the typical shape of the spatial intensity of the synchrotron radiation from a charged particle? You know, this:

As soon as I drew it and heard the giggles I knew what they were getting at. I had not anticipated it at all. It did not help that I drew it in the more exaggerated fashion that […] Click to continue reading this post →

Making Movies, 2

still_from_shoot_5_smallReally, I suppose this should be entitled “Making Movies, 1”, but I think that the earlier post “Call Me Cecil…” is morally the post of that title. Several days of insanity later (from worrying more about insurance, to locking in locations, worrying we would not get the HD cameras in time, trying to find a PA for the shoot, negotiating with various parties here and there about various things – in between the usual activities of physics professoring), the first big shoot day came. That was yesterday.

It was a day with record (for the date) heat (90+, in F), which was not helpful, but overall it was fun. On Thursday, in my location scout mode, I was to be found popping over once every hour or so to a particular location on campus and taking a snapshot. Why? I wanted to see where the sun would be at what time, so that we could figure out exactly when we could use the location, and for what shots. The sun […] Click to continue reading this post →

Call Me Cecil…

…Well, just for a 24 hour period or so.

Why? Well, it’s just that one of the many projects I’ve not yet had time to report to you about is inching along, growing ever more involved, has been sucking up a huge amount of time recently, and is going to go really large this week.

What’s “going large”?

Ok, here goes. I’ve been taking a turn at being a filmmaker, on and off, for over a year now. I hope that the products of this will be coming to a theatre near you one day soon (probably your computer), but let’s not get ahead of ourselves. What is it? Much more later, but I’ll just say now that it’s got science, and it is educational and – I hope – fun.

So far, what have I been doing? Writing a script, sketching storyboards, waving my arms about trying to explain the concept to actual filmmakers (you know, ones who […] Click to continue reading this post →

Pit Visit

I promised a report on last week’s College Commons trip to the Page Museum at the Tar Pits, here in Los Angeles. It was an excellent trip. The usual thing I do for blogging these things is, some time later, as time allows, I sit down and do a sort of brain-dump. I tried to do something different this time, and walk on the tour with my Palm Tungsten (yes, really really old technology, I know) and simply write a sort of narrative into it as I went along. Then I combined the uploaded file with the images I took as I went along, and supplemented with some extra sentences here and there. The overall effect should be a sketchier description of the event than I usually do, which may or may not be an improvement given that everybody seems to skim everything these days anyway. (Click on the photos for larger views.) So, here goes:

tar_pits_trip And so it begins. And it begins well – after a name tag is given out, upon check in for the bus, we are given a little brown paper bag of snacks. Hurrah!

3:39 and we’re off! (We run by the excavations for the Expo line and since it is an elevated bus, I get a nice view of what’s going on for quite a way. Wish I’d had the camera out to make a video for you.)

My colleague David Bottjer, a paleontologist, gives a little run down of the history of the region (both social and paleontological) as we go north on La Brea (appropriately – they are the La Brea Tar Pits… Or given that La Brea means The Tar, they are The Tar Tar Pits…)

4:05 We’re here! Somehow, the little bag of goodies is all empty already. Except for […] Click to continue reading this post →

Pit Stop

saber toothed catI’m going to another interesting College Commons event today. It’s an away mission. We’re off on a specially arranged tour of the La Brea Tar Pits! This is part of the 1859 celebration series, and of course Darwin is the focus here to some extent. We’re going to be taken around the famous Pit 91. I shall try to take some pictures and report later. The image on the left is a painting of the saber toothed cat, by John C. Dawson. (It is in the LA Natural History Museum.)

The Spiritual Life of Plants

cvj sowing seedsGiven all the gardening I’ve been doing over the last week or so (there’s some seed-sowing action going on to the right – more later), it may be fitting to go and sit and participate in the event coming up today. It is another of the College Commons events I’ve been mentioning here.

It’ll be a round table discussion and workshop to kick off a series, and here’s the summary:

“The Spiritual Life of Plants” series, arranged by Natania Meeker and AntĂłnia Szabari of French and comparative literature, aims to reunite urgent contemporary conversations around ecology and the built environment with an early modern past — a past in which plants existed both at the limits of being and at the frontier of new forms of knowledge. What might these animated plants have to tell us about the ways in which humans experience, regulate, and are transformed by the non-human beings that surround them? How can we carry these conversations forward into the present and the future?

Waiting for Stephen

Well, the last couple of days events were tiring, but good overall. The Hawking event was a bit like a rock concert. I made a video of some of the long line for you, and also take you into Bovard Auditorium with me to see the rather nicely packed crowd (well the downstairs part) of about 1200 excited audience members. At the end of the video are a few stills, showing Dean Howard Gillman during his welcoming remarks to the College Commons event, Nick Warner introducing Stephen Hawking, the man himself, and some of the high school students and the undergraduate student, who won the prize to get to ask Stephen questions. (The high school students had all asked similar questions, and so were all asked up to ask one question.)

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 →

Expensive

By | | , , ,

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 →
