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

[Warning! This is an unusually technical post.]

Ok, so last time, I told you a bit about the motivations for what I’ve been up to. Now I want to simply show you some of the product. I’m going to use pictures, words, and equations. I will lose some of you, and for that I’m sorry. But I hope that the words will still give you the gist of the thing. I’ll answer some of your questions in the comments.

Consider the following equation (first found and studied in this context in about 1991/1992 and reported e.g. here, and here, and here):

Well, I suddenly have 45 extra minutes on my hands as I was supposed to be at a very interesting two hour lunch meeting which I’ve now missed. I learned the hard way that we have in addition to the Annenberg School for Communication, the Annenberg Center for Communication, which is of course in a completely different location, North of main campus. I spent half the meeting running around the wrong place trying to find it, and no-one at the School could help me because they did not know anything about it, until after a long time someone had the bright idea of telling me about the existence of the other place….sigh. So I have some time to devote to you, dear Reader, and it will help me calm down from the frustration of it all.

Well, I promised a long time ago (since some of you asked) to tell you what it is that I am working on in my physics research. The problem always was that if I had time to Click to continue reading this post

Below is a snapshot of a computation I was working on earlier this Summer. Will explain later. Spoke about it at the Southern California Strings Seminar.

I’m curious about what a physicist’s scribblings look like to others, regardless of field (science or non-science). So, non-specialists: What does this all look like, to you? What impressions do you get, if any? Do tell.

There’s no wrong answer here.

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.

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.

Ice, Ice, Baby

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.

This is a Tough One

blog on a bikeWith the rise in gas prices, I’ve been seeing more and more people on the streets, walking and cycling, and more people using the subways and the buses. While I know that it has been producing real hardship for some people, I have to admit that it has been fantastic to see this change. So many streets and street corners have come to life. It has always been clear that higher gas prices would have this positive change, and I’ve hoped for it in some ways, but I wish that it had not come about in this way. I’d rather that it was because we’d managed to break out of a political climate so selfish and naive that nobody could propose raising taxes to an extent that would simultaneously give an incentive for people to use their cars less while at the same time providing much needed revenue with which to improve public transport infrastructure. Sadly, instead we’re just having high prices with nothing to show for it but a bunch of expressions of anger, while the oil companies and producers get fatter and fatter.

When I say I’d been hoping for higher prices, I need to clarify. I’m completely aware of Click to continue reading this post

Infiltration

Ok, so which one of you is responsible for this? (Since I started writing the post, I’ve since learned the answer – see below.)

Inside CDF!

There’s a new website that allows you to tour CDF, the particle physics detector at Fermilab, in Illinois. Jenny Lee, who worked on the site, said that it is:

CDF detector, Fermilab“a sort of `virtual tour’ that takes the viewer through each section of a particle detector, and includes photos, interviews with physicists, and more”.

The link to it is here. It looks great. Go and look, and spread the word about it!

When We Left Earth

This is a quick note to let you know about the Discovery Channel show “When We Left Earth”, which celebrates NASA missions over the last 50 years. I have not seen it, but it looks like it’s rather good. It’s on Sundays, and started last week, but you can still see all the shows. Look here for the schedule. Tonight (Saturday) there is something special on (I got an email about this from one of the people who works outreach on the show). There’s a live chat with one of the executive producers. Here’s what they say:
