There Goes the Weekend

viscosity_scatterI’ve no idea why I do this to myself. I was just about managing things schedule-wise and aiming to make sure I have some fun on the weekend when the following thing happened. I went to Monday’s departmental colloquium and before it, ran into Moh, our organizer this year. I’d been trying to see if there was still room to schedule a speaker I’d thought of inviting, and he mentioned that the dates we’d earlier discussed had all been filled. Then he mentioned that he was desperately trying to find a speaker for next Monday, and was thinking that he’d have to simply cancel it that week.

This was at 4:05pm. Now watch how rapidly I move to ruin a perfectly good schedule […] Click to continue reading this post →

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 →

Forward Looking

optometerySo, do you like it? My new glasses. Think it’s a good look for me? Sort of gadgeteer-scientist extreme. With this I get all the different optical instrumentation combinations I need in one nifty device. Long distance viewing for seeing whether my bus is coming from a long way away, lenses for extreme closeup work in the workshop, night vision, the works…Neat, no?

Ok, I’m being silly. I went to the optometrist today after a bit of a long period between tests, and I always find it an interesting experience. I’m not sure why, but it […] Click to continue reading this post →

Snooky

tribute-to-snooky

Still from the closing piece of the short concert in tribute to trumpeter Snooky Young on the occasion of being awarded the first LA Jazz Treasure award. This was on Friday 11th September, at LACMA. (Don’t you long for a time when everybody had nicknames like this as a matter of course? Well, it is more of a matter of place and culture than a time, in some ways, but anyhow… What would you choose yours to be, if you had the choice?) There are some trumpet players of note on the stage at this point (Arturo Sandoval is one, I cannot identify the others by eye), and Snooky himself is there too. He’s the one looking endearingly like a Mathematics professor (which, now I think about it, sort of fits for a trumpet player).

While it was a pleasant enough event, and I am glad it took place, I can’t help but think that it would have been greatly improved by not having quite so many official […] Click to continue reading this post →

Laser is Coming Soon!

Well, here it is. After lots of interruptions over the last 24 hours, I give you the trailer for Laser, the next of my films. I think it is a bit more playfully enigmatic than the trailer for the first film. (I’ve only just (half an hour ago) finished recording the music for it, and so it really is being rushed to you straight from the cutting room, as it were.)

See earlier posts for my thoughts about the project, and see the trailer for the first film here, and the actual first film, Shine a Light, here. Sorry it is so late… the semester started and I got swamped. See my chatter about that here.

Anyway, here it is! Enjoy!

A Little Behind…

By | | , , ,
1 Comment

Well, here are a few thoughts:

(1) I’m behind on pretty much every deadline. In addition to the externally set ones (article to finish, class material to prepare, etc), I’m behind on those I’ve set myself.

(2) An example of the latter is the fact that I am two weeks late bringing out the film “Laser”, the followup to “Shine a Light”. The semester started, and all the time I thought I’d have to sit and cut a trailer for it and record some music to go on it never materialised….

(3) …Until the last 24 hours. I cut together some images into an interesting (I hope) sequence, and just now finished recording some music onto it. It is more enigmatic than the last trailer, or at least that is the intention. It is being crunched on by YouTube right now and when it is ready I will release it to tease you to return for the […] Click to continue reading this post →

Thursday was Monopole Day

By | | , , , ,

Here’s an odd coincidence. Thursday, just for fun, I declared it Monopole Day in my facebook status. It was largely because I was prepping a class on Dirac’s ideas about magnetic monopoles (roughly: point sources of magnetic fields analogous to point sources of electric fields), why it seems (from looking at Maxwell’s equations – the defining equations of electricity and magnetism) that Nature might very much like the idea of them (using a symmetry argument – roughly: electric and magnetic fields can turn into each other so if there’s one kind of point source, isn’t it strange that there’s not the other?) but chose to hide them away…

monopole_workIt’s a favourite topic of mine (and many physicists – it is one of the first grown-up tastes of modern ways of thinking about physics that you get as an advanced undergraduate, actually), and so I was excited to lecture about it (as I am every year… I find en excuse to bring monopoles into every course I teach… almost). I even handed out one of my class worksheets, which was all about how to build a monopole (on paper – you take a semi-infinite solenoid (a “Dirac String”) and let the magnetic flux lines spill out […] Click to continue reading this post →

New Year Gear

One of the things I seem to do each year is replace my tyres (tires? always confused about the spelling there…) on the Brompton for another year of cycling around the city (often in combination with public transport).new_shoes_for_brompton_2 The beginning of the academic year seems to be about when I do it, which feels right somehow. It reminds me of my youth, when the night before the school academic year started there’d be frantic sewing of new school uniforms, or adjustment of old ones, to be worn the next day. I remember that always being a last minute thing, […] Click to continue reading this post →

Head in the Clouds…

clouds_and_smoke_2Stepping back from the unpleasantness going on at ground level for a moment (see the four previous posts, 1, 2, 3, 4), it seems that there is something else going on that’s actually quite fascinating. I went over to the top of one of the USC campus parking structures to take a look and gather some data and I’ve been chatting to people at random about it*. (This might also be a sign that I’m procrastinating on some other task… 🙂 ) That white part of the cloud is not smoke, is it? It is actually a cloud of vapour. Like a cumulus cloud you’d normally see in various weather conditions. I’ve heard some chatter about these systems “making their own weather”, and I can see that you could get a lot of localized heat dragging air in from other areas and so creating winds and so forth, but is that also generating this cloud? If so, how? Where is it getting all this moisture from? Is it from the water that is being […] Click to continue reading this post →

My Achilles Heel

Heat. Following is a little bit of a whine. You’ll be even less sympathetic once you read the postscript, but such is life. Once the temperature gets up to a certain point, I can’t think any more. Well, not at the level needed to earn my living, if you see what I mean. Long periods of concentration start out well, but usually just turn into a nap. Not good at all, really. For the second or third day running we’ve had super hot temperatures with little movement of air to ensure a decent amount of throughput. This is not always unworkable, since one can simply nap during the day, do tasks that don’t require much sitting and thinking, and then work in the very early morning hours, but this time around there are two additional effects that ruin that approach.

fires_with_downtown_laThe first is that the heat has been carrying on into the night (as opposed to dropping away rapidly in the evening as is the usual pattern), and the second is that there are two huge fires nearby, making the air a bit… chewy. (Left is a shot I took of downtown Los Angeles from the South showing the huge clouds of smoke from the La Canada and Altadena fires in the San Gabriels’ foothills in the background. From some views it looks like there’s been a small nuke detonated. Anyone remember 24 a few seasons ago? For some maps of the fire’s progress see here, and a view from one of the Mount Wilson observatories is here*.)

Both of these make for less than great sleeping conditions, and the feeling of lack of […] 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 →

Toe Temptation

By | | , , ,
8 Comments

So the other day I was sitting chatting with someone I’d just met and at some point I looked down…and jumped a little in surprise at what I saw. Those shoes were a surprise since for a moment there I thought the person is rather unexpectedly barefoot – but the colour is even more unexpected. Then there was maybe a tiny X-Men moment (Oh! It’s Mystique…) but this all happened all in a flash before settling on the correct answer – it is a kind of shoe I have not seen before. I’d seen the cloven hoof type of shoe, which can have a sort of cheeky and slightly electric beguile to them when worn by a woman with the right devil-may-care attitude, but these were new to me. Worn with boldness, these can really work too, and maybe in the same way, but it is a dangerous tightrope to tread (the person I was meeting with pulled it off admirably!).

Upon returning home I looked them up a bit more (they are called Five Fingers shoes) and I oscillate between giggling at the whole idea and being intrigued. I gather that they are hugely comfortable and that grabs me. But yes, they are somewhat singular. They are so utterly unconventional that I find myself amused by the idea of all the “inappropriate” places I could wear them to. Witness some of the levels of amusement:

tomato_red_gold_green

Harvest time. Seriously depleted crop due to the Great Tomato Atrocity, but the countermeasures have allowed me to claw back a little satisfaction. Now time to see about making some nice chutneys or other preserves. By the way, have you noticed all the stories in the press about the sudden rise of interest in gardening to grow food at home? See/hear an interesting NPR one here. (Many claim it has much to do with the Obamas’ White House garden, but you and I know it is all because of my blogging about it here over the years, right? …Right? ;))

Aaaaanyway… here are some other shots of the harvest/harvesting: […] Click to continue reading this post →

Of Red Carpets, and Cooking

premiere_prepMy films are finished! There’ll be more on them here later (including their online premiere), so check back. I might even try to find time to cut a trailer for the first one soon.

Being somewhat insane, I’ve decided on the (sort of) spur of the moment to have a (tongue in cheek) red carpet premiere of the films this weekend. I’ve a confirmed list of 20 hungry guests coming (mostly friends who are filmmakers, writers, actors, journalists, educators and other related professions), and I’ve promised to prepare them lots of food and drink. (Well, the films are very short.) It is already late in the day and I’ve been procrastinating instead of starting my prep. As usual.

Anyway, I’ve decided to plan a few long-prep centerpieces, and will improvise all the other dishes based on whim, the Farmer’s market offerings later, and how many of […] Click to continue reading this post →
