## Cabinet Caper!

Remember I mentioned that I was building something? Well, I finished the project:

The usual thing happened. I could not find the right kind of cabinet that fit the space and function, and so decided that I might as well build one designed to fit exactly what was called for. It holds all the living room media needs, and keeps them discretely hidden away (no electronics and cables everywhere) until called upon. The top chamber opens up to deploy a projector (the holes […] Click to continue reading this post

## Pie Puzzle

A Thanksgiving Puzzle for you: From yesterday’s kitchen adventure. -> You decide which order I did things in….

## Monday’s Quarry

Monday’s quick grab on the subway on the way to work. I claim that one of the most useful aspects of the smartphone is its facility for holding people in predictable poses in order to be sketched.

He had a very elegant face and head, and was engrossed in his game, and I was done reviewing my lecture notes on scattering of light, so I went for it. I was able to get out my notepad and a pen and get a good fast […] Click to continue reading this post

## Look Up In the Sky…!

Yesterday’s graduate class in electromagnetism had a bit of extra fun. We did a particular computation in some detail, and arrived at a pair of results. We thought about the main features of the equations we’d derived and I then asked the class if they could think of an example. An example with those equations essentially written all over it. It was the sky. Not just the blueness of the sky (for which the result supplies a partial answer) but the pattern of blueness on the sky, especially when looking through your polarised sunglasses. (You know how you tilt your head when wearing them and you can darken or lighten the sky a bit? Well, that effect is way more effective if you are looking in a direction at right angles to the sun as opposed to either toward or away from the sun.)

So I took the class outside to gaze upon the sky in person, rather than just sit and talk about it. Actually, a little bit of knowledge about the pattern of blue in the sky is useful in a lot of ways. For example it is amusing to me to see how often architects and their artist collaborators get the sky wrong in renderings of […] Click to continue reading this post

## Luncheon Reflections

You know, I never got around to mentioning here that I am now Director (co-directing with Louise Steinman who runs the ALOUD series) of the Los Angeles Institute for the Humanities (LAIH), a wonderful organisation that I have mentioned here before. It is full of really fascinating people from a range of disciplines: writers, artists, historians, architects, musicians, critics, filmmakers, poets, curators, museum directors, journalists, playwrights, scientists, actors, and much more. These LAIH Fellows are drawn from all over the city, and equally from academic and non-academic sources. The thing is, you’ll find us throughout the city involved in all sorts of aspects of its cultural and intellectual life, and LAIH is the one organisation in the city that tries to fully bring together this diverse range of individuals (all high-acheivers in their respective fields) into a coherent force.

One of the main things we do is simply sit together regularly and talk about whatever’s on our minds, stimulating and shaping ideas, getting updates on works in progress, making suggestions, connections, and so forth. Finding time in one’s schedule to just sit together and exchange ideas with no particular agenda is an important thing to do and we take it very seriously. We do this at […] Click to continue reading this post

## Chalkboards Everywhere!

I love chalkboards (or blackboards if you prefer). I love showing up to give a talk somewhere and just picking up the chalk and going for it. No heavily over-packed slides full of too many fast moving things, as happens too much these days. If there is coloured chalk available, that’s fantastic – special effects. It is getting harder to find these boards however. Designers of teaching rooms and other spaces seem embarrassed by them, and so they either get smaller or disappear, often in favour of the less than magical whiteboard.

So in my continued reinvention of the way I produce slides for projection (I do this every so often), I’ve gone another step forward in returning to the look (and […] Click to continue reading this post

## Three Cellos

These three fellows, perched on wooden boxes, just cried out for a quick sketch of them during the concert.

It was the LA Phil playing Penderecki’s Concerto Grosso for Three Cellos, preceded by the wonderful Rapsodie Espagnole by Ravel and followed by that sublime (brought tears to my eyes – I’d not heard it in so long) serving of England, Elgar’s Enigma Variations.

## Nerd-Off Results

So I’m supposed to be writing 20 slides for a colloquium so let me see if I get this right really fast:- First round, the Koch Brothers bested the Justice League and Ultron was beaten up by Inspector Gadget meanwhile Ice Cube trumped Mr. Rogers and Stephen Hawking battled Charles Darwin but the audience loved them so much that they were asked to team up for the next round (before which Jon Snow did standup in the break) and in which they lost to Inspector Gadget who […] Click to continue reading this post

## Nerd Judgement

I’ve judged Poetry battles a number of times, essay competitions, art displays… but never Nerd-offs. Until tonight. Come to the Tournament of Nerds around midnight tonight at Upright Citizen’s Brigade. I’ll be one of the guest judges. I’ve no idea what I’m supposed to do, and my core “nerd” and … Click to continue reading this post

## Interstellar Science at Screen Junkies!

As promised on Tuesday, below you will find my Screen Junkies interview where I chat with Hal Rudnick about some of the science in Interstellar. We covered a lot of topics and went into a lot of detail, but a lot of that is on the cutting room floor in order to make a svelte (but relatively generous) ten minute cut. I hope you enjoy it. (See my earlier thoughts on why I think scientists need […] Click to continue reading this post

## Subway Glances

Just a few grabs of parts of faces of people who I see on the subway journey to and from USC each day. Sometimes I get a good look, other times not… Sometimes they disappear before I get anywhere. I’ve been busy on other things (like prepping lectures and reading endless books and files for one duty or another) and so have not got as many done as I like to. This collection is about three weeks’ worth. Also, when travelling in rush hour I seldom get a […] Click to continue reading this post

## Southern California Strings Seminar

The UCLA group is hosting the next Southern California String Seminar, the long running once a semester (mostly) regional event that roves around the various high energy groups in the region (more here). It is on Friday!

There’s schedule and other information here. The schedule goes something like this: […] Click to continue reading this post

## Hanging out at Screen Junkies!

Just finished another enjoyable hour of chatting about movies and science with the Screen Junkies guys! You’ll recall the fun results of the last two (see here on Time Travel and here on Guardians of the Galaxy). We were talking about… wait for it… Interstellar! Their legions of fans have been shouting at them to do something about the science in Interstellar for weeks now, and they heard them, and called me in to chat. In the course of an hour we talked about a lot of fun things, but remember – they’ll cut it all down to 5 minutes or so, and so we won’t get to a lot of things. I do not know what bits will be used… (It will be different from my spoiler-free recent Interstellar discussion.)

In my previous visits there I’d never got to see the famous Screen Junkies wall in front of which they have conducted so many fun interviews (see their site […] Click to continue reading this post

## Interstellar Thoughts

After emerging from a spectacular 70mm viewing of Interstellar at the Arclight Dome last night, I was grinning from ear to ear, which is unusual these days after seeing a film in this subject area (science fiction, space travel, the future of humanity, etc). (And by science fiction here I mean proper science fiction, not space opera or space adventure. There’s a lot of that and some of it is fun and makes me grin too, like this Summer’s Guardians of the Galaxy. But that’s not at all the same sort of thing.)

I’m not going to go into any details, since I am very tired of the practice of talking about films to the extent that you say so much of what happens that it is impossible for someone to enjoy watching the film unfold in front of them without knowing what comes next, the way I like my films best. So I’m not going to ruin things for you.

Everybody keeps asking me “what did you think of the science?” since they know that there’s a lot of stuff in there that relates to my subject area and interests. Many seem to want me to pronounce on what’s “good” and whats “bad” about the science, as though I’ve (like many scientists in the public sphere seem to have done) elected myself some sort of guardian of scientific ideas. Let me say two things. The first is that this is a science fiction film, not a science documentary. I’m already hearing all sort of humourless declarations about this and that and the other being wrong and how shameful it is, as happened with Gravity last year. Done right, such discussions can be an opportunity to teach a bit about science ideas, but most often it just comes across as being a smartass, which is a bit tedious, and leads me to my second point.

The second point is something I say a lot and needs to be said a lot more: Scientists don’t own science and its concepts and ideas. We should be careful […] Click to continue reading this post
