Out There

cvj_scribbling_boardWell, I’m always a bit embarrassed to point to articles that are about me, especially ones that are decidedly generous – I’m British, remember – but it is specifically about some of the work I do when I’m not doing research, classroom teaching, sitting on committees, and so on and so forth. Things like blogging, and things that might be called “media outreach”. Lots of people ask why I do so much of this sort of thing, and so it is worth pointing to this recent piece by way of a partial answer. (The other part of the answer is to do with the response to and (possible) lasting effects of this sort of work. It is surprising in both quantity and variety, and quite humbling at times, and I’ll tell you about it in another post.) The article, written by Laurie Hartzell (with photo above left by Mara Zimet) for USC […] Click to continue reading this post

Collections!

Well that was fun! I’m sitting on the bus on the way home [editorial note: I wrote most of this on Thursday afternoon], with the memory of the College Commons event that I just went to still fresh in my mind. (That and the tasty food at the end of the event.)

ivory-billed-etc

This event (“Discovering the World: Collections, Curiosity and Evolution”) was all about collecting and collections, from the institutional collections we have in our society today such as museums and libraries, through the “cabinets of curiosity” of earlier centuries, to the sort of obsessive collections of random stuff that sort of becomes a disease (I mentally glance over at the shelves, piles, and boxes of old New Yorkers in my house; I’ve not been able to throw away a single one since I started subscribing in the early 90s. Yes, I know, I know… I know.)

So many of these types of collections (and the resulting books and compendia which they themselves become the objects of collections and subjects of books and so on and so forth) formed the foundations of the culture, the raw material for scientific study, the inspiration for more collections and for more study, and so on…. So the event used that as a basis and dug out some wonderful articles for us to look and marvel at. The digging was done at USC’s own splendid Doheny library (original Audubon volumes, Cook’s journals, etc) the Huntington library (several illustrated tomes of natural history and an actual plate used long ago for printing Audubon illustrations which were then later hand-coloured by artists) and the Los Angeles Natural History Museum across the street. A number of my colleagues who are scholars in areas that these objects pertain to gave short, informative and […] Click to continue reading this post

New Beginnings

campus_1Yes, the new semester and new academic year started yesterday, and today saw my first class of a new course for me to teach – Physics 508b: Advanced Electricity and Magnetism. The bad news is that it is a new course for me and so I have to write new material, plan new things entirely, and generally put in a lot of raw preparation from scratch for some things. The good news is that it seems that I have, overall, a good group of students to teach, based upon the willingness to interact that I saw, with good humour, good questions, interjections, and so forth. Further good news is that I’ve an excellent TA for the course (who also does research with me and so we can go back and forth from teaching matters and research matters) and that I’ve taught Physics 408b for a few years. The latter is an undergraduate advanced E&M course (based on Griffith, in case you’re wondering), and while this 508b course (based on Jackson) is heavier in detail and depth on the same material, I can borrow some of the more challenging material from the […] Click to continue reading this post

Scenes from Work

cvj_at_workThe College of Letters, Arts, and Sciences here at USC has built a new website, and gone quite far in including extra media, and links and portals on YouTube, Facebook and so on. One of the things they did was have a filmmaker make lots of videos. Lots. Things about faculty, research, teaching, learning, etc. All very exciting. Have a look, here, if interested. Mira Zimet, who makes the films, gave me a call and asked me if I’d like to contribute, and I agreed. I chatted on and on for about 45 minutes to an hour and she cut two short films out of it. The shorter one is on the site and has me saying some general things about research, teaching, science, and USC. Mira made the second because she thought it might be a nice extra video for the College’s YouTube portal. It has me talking a bit more about what string theory is and does, […] 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

NSF and NSFW

I’m sure there have been times when you received that message from the National Science Foundation saying that your grant application has been turned down, and in disappointment you’ve muttered something like “…bunch of W*nkers!” before taking a deep breath and moving on.

Right?

Well, now it seems it is official! See this story on MSNBC*, which starts:

Uncommon Conversations

college commons logo smallI almost forgot to mention that tonight marks the launch of the series of events called the College Commons here at USC. Here’s a news story about the programme. This academic year, I’ve been working on the committee working on shaping the ideas that have come up from the faculty (I had promised to tell you more about this), and we’ve announced the short Spring programme, which you can see here.

There is a featured part celebrating 1859:

Where do ideas come from, and how far do they travel? One hundred and fifty years ago, the astonishing year of 1859 saw not only the publication of Charles Darwin’s The Origin of Species, but such pioneering works as John Stuart Mill’s On Liberty, Charles Dickens’s A Tale of Two Cities, Karl Marx’s Critique of Political Economy, and Richard Wagner’s first version of Tristan and Isolde. This year also marked amazing advances in travel and communications, the first battles prefiguring the Civil War and the first trapeze act performed in Paris. Can we imagine the world 150 years from now, and imagine the place our ideas will have in it? Scholars from biology, anthropology, physics, literature, history, and gender studies, as well as poets and artists, will explore these questions together this spring.

I hope there’ll be a lot of participation in the events (I’ll say more on this later). Tonight has a free movie, Master and Commander (so there’s a reason to go, right […] Click to continue reading this post

Not All Academic

I just have to say…Slumdog Millionaire is indeed a fantastic film. In case you were wondering if you should go…. just go. It is well written, acted, and beautifully photographed and directed. I’m pleasantly surprised that Danny Boyle could make a film that feels quite so authentic (while at the same time being essentially a fairy tale) as an Indian film. Quite splendid.

Speaking of excellent films of 2008, and turning to a more academic context, I’d like to urge you to take a second look at The Visitor, if you’ve not yet seen it. It’s nice, from time to time, to see films where the principal characters are academics, and this one does a very good job at having a good feel to it – in the sense that the lead (played wonderfully by Richard Jenkins) felt believable as a professor going through a strange time in his life, and then finding himself increasingly falling into an unfamiliar world. It is one of my favourite films of the year, and it seems that few people I know have even heard of it.

While on the subject of 2008 films featuring academics, I’d like to mention Smart People. I really did not like it at all. It is not that most of the principal characters […] Click to continue reading this post

Snowed Under

Ok. It’s official. This week I am snowed under with things. Every day I write half a blog post, and then something comes up and I do not got back to it and I fall into bed later, exhausted, some time in the wee hours, only to get up early the next day to carry on with things.

So in case you were wondering, I am still here. Just snowed under. I gave my final exam for my Physics 151 course (Fundamentals of Physics: Mechanics and Thermodynamics) on Monday (hurrah!) and I’ve spent a huge chunk of today playing with various excel files of various chunks of data from the course, trying to turns a sea of numbers into final grades for the students. It has been slow work, and I’m nowhere near done yet. It’s complicated because I must incorporate multiple components of assessment, from three different exams, laboratory work, online homework and written homework, to in-class responses using individual RF transmitters, and online quizzes of various sorts. (All a bit much, in my view, but, well that’s another story…) Every single bit has its own spreadsheet with data that must be uniformized and then combined to give the whole picture of each student’s performance.

It has made me a bit dizzy just talking about it.

But it’s not that simple. Oh no. Here’s a small part of the extra stuff: I’ve been trying to get the exterior of my house painted, and of course there have been (quite fantastic) rainstorms delaying everything and so I’ve been dealing with painters for longer than planned – with the Christmas holiday closing fast, and I’ve got my mum visiting me (hurrah!) and so I must be a good host and so forth and not just hide in the study crunching numbers (she arrived a day earlier than I expected – my fault! – so I’m a bit off-balance about that too), and… and…

Are We There Yet?

Well, no we are not.

Are we making progress? Sometimes I think we are, and other times I’m not so sure, but what do you think?

I’m talking about that thing I talk about a lot: science and scientists being part of the broader culture. This time on TV. A recent LA Times article by Mary McNamara (one of their television critics) surveys a number of shows on TV in this context and is, on balance, rather positive about where things are compared to where they used to be. I’m inclined to agree (and I should say that I found the article itself rather valuable as a quick survey – I don’t keep up with all the TV produced out there, and found myself surprised here and there). She also quotes conversations with Jennifer Ouellette (of Cocktail Party Physics) and yours truly on the issue, (mentions the recently established Science and Entertainment Exchange I blogged about two weeks ago), and overall produced a pretty good article. (The full article is here.)

I’m still on the fence about all this, though. Once you scratch the surface a bit, I don’t think there is yet a single example of what I think is possible, and what I think should be fairly routine before we declare that […] Click to continue reading this post

One in the eye for Big Textbook?

Well, back to teaching issues. Textbooks. I know the following is illegal, but I will admit to being hopeful that this will supply a much needed kick in the rear end for the “textbook industry”. (The very term makes me a bit ill sometimes.) In teaching the big courses at freshman or sophomore level to classes that have a couple of hundred students (broken into sections – we don’t like super huge classes here at USC) enrolled, it is hard not to notice that there’s something slightly insidious about aspects of the textbook game. Despite the fact that we are teaching subjects (Newtonian physics, thermodynamics and a brief bit of “modern physics” that is mostly from no later than 1905) at levels that have not significantly changed for over a century (in some parts, several centuries), the Industry (shall we call it “Big Textbook”?) keeps finding new excuses to come up with new editions. These editions get more and more expensive, and heavier and heavier to carry around. I don’t know why this is necessary, except to force new students to buy the books all over again.

Additionally, the new hook is to combine the book with an access code for further […] Click to continue reading this post

Thoughts During Break Time

Ah. I see that it’s been three days since my last confession. Gosh.

Well, it’s been a quiet weekend here in, er, my part of the universe. Good time for reflection and rest. I had a couple of posts I was going to do but in the end decided to break the pattern and change up my Saturday and Sunday, and the “change up” did not include the blog. So sorry about that.

I’m taking a break between an interesting meeting (that I will tell you about) and my office hour. The sun’s shining outside and it is not oppressively hot, surprisingly, so I’ll keep this short and poke my head out there again before my Physics 151 visitors arrive.

Some of the things on my mind: […] Click to continue reading this post

On Good Ideas

A commenter, slim potato, implicitly asked a really good question earlier. It was a comment on a post I did yesterday about my struggles with a computation I was working in a notebook working on. I gave an answer, but since I know that a lot of readers don’t read the comments, and because one of the missions of this blog is to give a window on what scientists such as myself do and (importantly) how we do it, I thought I’d elevate the comment and my response into a post. Feel free to add your own thoughts to it in the comments, either as a non-scientist, a scientist, a specialist from another field, or other.

I would have assumed that most of your time when working on a paper was involved on catching good ideas, not getting muddled with conventions and calculations.

Hi,

Thanks. That’s a common misunderstanding of what we do. What makes a field of physical science like physics work is computations – all of that business with calculations (including checking that your computations conventions are internally consistent) is vital to the field.

Frankly, “Good Ideas” are a dime a dozen. Anyone in my field ought to be able to think of at least six of them before breakfast. What makes a good idea go […] Click to continue reading this post
