The Universe Lives!

(Seems a highly appropriate title to use when up at 4:00am listening to the excellent violent wind and rain storm that’s going on outside.) This is mostly a note for fans of the show The Universe, on the History channel, or H2, and channels by other names internationally. I just wanted to say that the show is going to carry on, with a new season coming out early next year!

I mention this because it looked for a while (at least a few times) like there wouldn’t be another season (after a solid 7 or 8 seasons over as many years), and then at the last minute they greenlit that short season that aired earlier this year with the subtitle “Ancient Mysteries Explained” or something worrying like that (because it sounds a lot like the “Ancient Aliens” show which, well, I’d rather it did not sound anything like…) Then it was not clear again whether that was just a last hurrah or not…

Well, it was not, since we’ve been shooting for several episodes this last month or so! Looks like there will be at least a short season coming, with the same subtitle. I’ve done some work on a few segments that will appear in two or three episodes. They wanted me to do more but I had a rather busy period coming up and so declined to do any more shooting days after November, so I’ll be somewhat fleeting in my appearances, but hope that the physics I did get to talk about is clear and interesting – assuming they use those bits at all (you can never tell).

My favourite day was when we were out at Zuma Beach, which I think I mentioned in a short post a while back. The episode focuses on contrasts between Astronomy and Astrology, which is certainly a good topic! I came up with a fun analogy with which to explain a certain idea and we enlisted a group […] Click to continue reading this post →

Grabbing Fun Shapes

culver_city_building_8th_dec_2014_smallA quick sketch of a building in Culver City, done while waiting for a meeting to finish (I was in my occasional role as chauffeur). A very classic and pleasing combination of shapes for Southern California. (I splashed on ink and colour later on, once home).

In other news, I’m all ready for the last teaching event of 2014. I’ve written, typeset, and checked (multiple times) the final exam for the graduate electromagnetism class. There are some interesting things on there. I hope they like it!

LAIH Field Trip: The Clark Library!

laih_clark_library_visit_2014_07One of the things I want the Los Angeles Institute for the Humanities (LAIH) to do more of is field trips – Exploring the city together! We’re an LA resource (as I’ve said in earlier posts) and so we should visit with and strengthen our relationships with some of those other LA resources, whether they be physical places, or groups of people (like us), etc.

Friday saw us take a wonderful field trip to the William A. Clark Memorial Library. It is another of those classic LA things – an amazing gem hidden away that you pass every day and don’t see. It is not far from USC, and in fact a number of USC faculty I know have used it regularly for research, since it has several important collections of papers and rare books of various sorts (Oscar Wilde, Shakespeare, Edgar Allan Poe, etc).

A lot of these were put out for us to see by Head Librarian (and LAIH Fellow) Victoria Steele and her staff, and they gave us a guided tour. During the tour […] Click to continue reading this post →

Black Hole Slides!

black_hole_heat_engine_snapshot

Since people were asking for copies of my slides from my colloquium chalkboard-style talk on black holes and the things I call “holographic heat engines” last month at Harvey Mudd College, I decided to export them as a movie. You can find it on YouTube. Link below. It was a 50 minute talk, but all the builds are compressed down to a 6 minute file! I try to keep the bulk of the narrative in my head and speak it with the slides as visual aids (instead of writing everything on the slides as is often the practice) and so I do not know […] Click to continue reading this post →

The Imitation Game – Thoughts

Since this time I don’t think I’ll be getting the call from the folks at Screen Junkies to talk about this one, I’ll do a quick post on my thoughts while they are still fresh. (There are no real spoilers in what follows, but if like me you like to know as little as possible about a film before going to see it, forming your own opinion before having to see the film filtered through those of others, do wait until you’ve seen it before reading beyond the second paragraph.)

I enjoyed the film very much. As a piece of human drama, it was a great story to tell, and frankly it does fill me with dismay that few people seem to know the story, so I am glad it is getting mainstream attention. It was done extremely well, in terms of standard things like all the acting performances (more or less), photography, and the overall tone of the direction. Given the subject matter – its social and historical importance – this was a beyond the ordinary human drama well told. I enjoyed it.

But. BUT…

But it missed an opportunity to not just be “beyond the ordinary” but truly exceptional and ground breaking. All we needed was about 5 or so minutes of extra screen time to achieve this. I’m talking about the ironic fact that Interstellar, which is I remind you a science fiction film (which many scientists […] Click to continue reading this post →

Cabinet Caper!

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

completed_cabinet

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 →

red_line_guy_24_11_2014_smallMonday’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…!

graduate_electromagnetism_class_sky_watchingYesterday’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

LIAH_Hawthorne_luncheonYou 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!

black_hole_engines_slide

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

three_cellos_14_11_14These 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

UCB_nerd_offSo 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 →
