Although No News is Good News…

…(as the saying goes) it’s nice to get the real thing from time to time.

I’m almost fully in retreat mode now, being back at Aspen and settled in to my office at the Center and so forth. It’s good to see some familiar faces and catch up a little on physics news, and gossip (still waiting for some good juicy stuff there). I’ve settled into my accommodation (which on the plus side has no wireless or other web connection, but on the minus has HBO, which I shall have to studiously avoid), and have done a quick cycle around town (brought the Brompton again of course) to check that everything is in order. So by mid-afternoon on day one, yesterday, I was settling into my project(s). All good.

The good news of the title? Well, usually when someone contacts me about my book, D-Branes […] Click to continue reading this post →

Stuff

Spent Sunday intensely preparing to leave on a trip, starting at 6:30am, with few breaks. This involved time spent preparing the garden to look after itself (I’d added several plants over the last six months that were not on the drip system), preparing various rooms to be more easily traversable for some contractors to do some plumbing and other work while I’m away, doing endless bits of paperwork and related things that I don’t want to deal with while I am on retreat thinking (almost) exclusively about physics, and so forth. At 3:30pm, in a panic I began the run around the house grabbing all the stuff I wanted to take with me, and going down to storage to bring up the two large bags I always take with me to Aspen.

hard case for the bromptonStuff includes notebooks, computer, hiking boots, bike, helmet, books, water bottles, drawing equipment, raincoat, umbrella, sketchbooks, shorts, t-shirts, underwear (yes, I did fly to a workshop one time and discover that I’d forgotten all my underwear…), various cables for charging various bits of consumer electronics, consumer electronics, shopping bag, small hiking pack, the pens I like to write with, the pencils I like to draw with, good tea, medium hiking pack, cloves, black peppercorns, good sea salt, whole nutmeg and a big stick of cinnamon (sort of hard to explain why these last several are important unless you’re also into a certain sort of cooking, and are familiar with […] Click to continue reading this post →

Fourth Thoughts

Have a Fantastic Fourth of July, to everyone who is celebrating it!

fantastic four promotional skywriting over LA on the July 2005

It’s been several days since my last confession. Sorry about the silence. I’m honestly not sure exactly what I’ve been doing, since it has been a mostly fragmented set of things, coupled with a generally down mood of introspection over matters personal. Hmm… So nothing new there.

Physics-wise I’m a bit stuck. Not on a particular project this time, but stuck on […] Click to continue reading this post →

Launch of an Idea

1 Comment

150 years ago today, Charles Darwin presented his theory of evolution to a group of his peers for the first time. It was read at the Linnean Society, and the reading didn’t really rock the world. That came later when Darwin published the Origin of Species. Either way, it is quite an anniversary today, since evolution is without question one of the single most important scientific discoveries ever made about how our world works. (Have a look at my earlier post on the Darwin Online Project, by the way. Lots to see there.)

Actually, Wallace had the idea some 20 years before Darwin, it is said, but few remember him. A recent NPR piece quotes the author David Quammen (”The Reluctant Mr Darwin”): […] Click to continue reading this post →

Goodbye to Correlations and WIRED Science

Over on Correlations, we’re in the process of saying goodbye. The PBS experiment with a genuinely new (for them) and fun science format, WIRED Science, along with its really fantastic online component (with resources for schools, the general public, the blog Correlations, and so forth), is officially over.

I don’t know exactly what went on behind the scenes at the PBS mother ship, but frankly, it seems that they just did not have the guts to try something new at this time, and are returning to their standard stuff. I thought that the show had a lot of good work in it, including several shining portions, and deserved a bit more time to find its feet. It may well have got there, building followers that would have tuned in regularly for years, becoming a sort of US (and science-oriented) version of the UK’s Tomorrow’s World (a BBC show that ran for 38 years and -despite its flaws- is fondly remembered by many generations). Oh well.

The mood at KCET (the local Los Angeles PBS affiliate that was making the show) was […] Click to continue reading this post →

Going Bananas…

…in the kitchen. A friend of mine has a number of banana trees that are producing fruit right now, and to help her get rid of her surplus I accepted a generous gift of bananas last week. (Thanks M!) It turns out that they have a remarkably strong flavour, concentrated a lot by the fact that they were already quite ripe when I got them. That strong flavour meant that I only managed to eat one of them in a given day, even though they are quite tiny.

Well, after some days I still had many of them, and now they were rather far gone down the road of ripeness. Too far, for my tastes, but I did not like the idea of throwing them away. It did not seem in the spirit of the gift at all. Then I hit upon the solution. This means, of course, a long overdue episode of: Asymptotia goes to the kitchen…!

My mum’s recipe could not be used at this point since she was travelling, and there’s an eight hour time difference, so I could not call her to ask for her method. Instead I consulted a replacement that’s sometimes acceptable in times like this: Jim Fobel’s Old Fashioned Baking Book. What was I looking for? Banana Bread.

Most, if not all, of what you need for a quick banana bread is probably in your cupboards already, if you’ve much of a cooking bent, so no special shopping […] Click to continue reading this post →

I Went Walking…

stairs in the hills. Los Angeles In some parts of the city, mostly older parts, while out on a walk you can stumble across lovely staircases nestled between houses.

Like many things in Los Angeles, they’re hidden gems – you’ll hardly hear about them outside the city, or even much beyond the neighbourhood they’re in, and you’ll certainly never encounter them by staying in your car.

So they remain largely unknown to that majority who don’t walk – even if they live near them! Here’s a particularly lovely one, spotted while I was lost in thought on a long wander (right: click for larger view), which had lots of welcome shade on a hot day.

Thesis Thoughts

Recently I was reading the PhD thesis of my student, Veselin. He was going to have his examination and so I was looking through a draft. He recently received a fellowship to go to do a postdoc abroad and so has decided that it’s best to write up and get everything done before it gets too late into the Summer. His new job requires him to have a PhD, of course. (He was, I’m happy to report, successfully doctored (as it were), after an excellent performance in his exam.)

I recall being in the same situation myself, 16 years ago. (Wow, so long…) Happy memories. I got a fellowship to go to my first postdoc in the mythical land across the sea, where so much of the wonderful physics I’d been studying was done by the giants of the field. I was going to get to go there and join them. But I had to write up and graduate first.

I loved writing (and, as you may have noticed, still do) and so relished the prospect. I procrastinated an awful lot (as I do…) for a while before getting down to it, even managing to catch chicken pox for a while (which helped keep me at home for a bit, usefully), and then eventually settled down to it. I essentially locked myself away at home for three or four solid weeks, with a little computer, in my room at the top of the […] Click to continue reading this post →

The next three posts are repeats of posts I did on CV in 2005. They were the first three in the series entitled “News From The Front”, and their subject matter partly lay the groundwork for a post on some new results that I hope to write soon. Enjoy! -cvj

Seven Hours of Wonder

One great thing to do when it is super-hot outside is to sit in an air-conditioned movie theatre. Yes, and watch a movie. And when its really hot, do it for a really long time. How about seven hours?!

movie poster of Bondarchuk's War and PeaceOver the last two nights I watched something wonderful on screen, at the Bing Theatre at LACMA (Los Angeles County Museum of Art). A rare gem, in fact*. Sergei Bondarchuk’s film of Leo Tolstoy’s War and Peace, (Voyna i mir) released (USA) in 1968, and in four parts (matching those of the book), each a full movie. I went with three friends (M, R, and R), since movie marathons are fun in company. The full print, in Russian and French with English subtitles, is seven hours long. This is not to be mistaken for the relatively paltry dubbed version cut down to a fleeting six hours duration. This is (closer to) the proper original version. It is rare…apparently not shown in the USA for a very long time, and apparently not available on DVD. (Arguably, it shouldn’t be seen on DVD on a screen that is inappropriate to the task, and without good company. This is a movie theatre movie if there ever was one.) It’s a national treasure, and frankly I have no clue how they made it so well.

The cinematography, set/production design, art direction, and – of course – direction […] Click to continue reading this post →

Happy Summer!

The first day of Summer sees us deep inside a heat wave here in Los Angeles. It was already very hot before 8:30 this morning, and the temperature continues to rise. Yesterday, I was booked to do some shooting for another episode of The Universe (History Channel), but happily it was cancelled due to the heat. I’m grateful since I was to be demonstrating aspects of Einstein’s Special Relativity by cycling at relativistic speeds* around a racetrack. More superpowers on display, or another remarkable feature of the Brompton? More later. This was to take place in the Valley, where temperatures were touching on 107 F, apparently.

Wandering the city on days like this can be fun. The first trick is to accept that it is super-hot and that you’re going to be sweating, and so dress appropriately. I always wear a hat too, and carry a filled water bottle, as it is easy to get dehydrated here. Everything then ends up being done in a dreamlike state. Everybody seems a little […] Click to continue reading this post →

Phoenix trench showing suspected uncovered iceHave you been keeping track of what Phoenix has been finding on Mars? There’s been lots of digging of holes, baking, peering at things under microscopes, and so forth. And, wonderfully, it has all been guided, monitored, and watched from here on earth. From all of this, there’s now very direct evidence for ice, for example. (Dig a hole, find white flaky chunks which disappear after exposure to sunlight…) (Image left (click for larger) is from the mission (credit: JPL/Caltech/NASA) and shows the before and after. Keep your eye on the darker corner, blown up in the inset.)
