Back to Bilbo, Again

Lorentz_DemoI’m preparing some notes for my graduate Electromagnetism class, and I’ve finally arrived at the section on Special Relativity. We will end up discovering the fully covariant formalism of the equations of electromagnetism in a few lectures, and a number of mysterious things we’ve seen over the course of the semester will be more natural in this setting, showing how marvellously Maxwell’s equations from the 19th Century, unifying Electricity and Magnetism, actually herald (actually should out loudly for!) Einstein’s 20th Century physics – Special Relativity.

But first I must review Special Relativity, going back to the basic thought experiments I like to talk about that lead you to discover it. Traditionally this means lots of scenarios involving flashes of light, and long extended objects being boosted at speed in various directions and so forth… All very fun.

Well, over the years I’ve changed the characters in the scenarios a couple of times, and now I’ve firmly (as of 2012) left Harry, his broom, Hermione, and […] Click to continue reading this post

Date Tastiness

walnut_date_bread_6Time for a quick visit to the kitchen. I woke up one Sunday morning with the urge to make a cake. I’d thought about a simple sponge cake for some reason in the days leading up to it, and that must have planted the seed. I was busy and so did not immediately jump into it. But I woke up the Sunday in the mood. (I think it was last Sunday.) So I looked at what I had lying around and remembered that I had some old dates that were needing a purpose. They’d dried out a bit and so were not so great for eating directly, but certainly had a use in cooking. A short time later I had a date and walnut coffee cake sitting on the counter waiting to be eaten.

It was all gone within a short time, and so this morning I thought I’d make some more. The pictures you see are some of the steps.

It is pretty simple, being a fairly basic (baking soda risen) batter. The key novelty is to put together a cup of dates and a cup of walnuts, all chopped, […] Click to continue reading this post

Fail Lab Episode 9 – Aggression

fail_lab_ep_9_stillFail Lab Episode Nine, all about Aggression, is now online. See earlier posts (listed below) for thoughts about this excellent series on Discovery’s Test Tube.

(By the way, (spoiler alert) in the video they analyze this week, that looks like a bit like a Wing Chun move (and stance) to me… albeit a tad sloppy. And I note that it was used to end the aggression. A win for positive use of martial arts!)

Why Do I Study Physics?

why_do_I_study_physics_stillI was sent* this delightful short film recently. It is by Shixie (Xiangjun Shi) done as a graduation project at Rhode Island School of Design. It seems that it won prizes – quite understandably! – at a number of short film festivals, including one about science communication (which reminds me of the one I run). The film is entitled “Why Do I Study Physics?” and it is a lovely piece of writing and hand drawn simple animation that’s very […] Click to continue reading this post

Consulting for a Cat…

love_me_cat_stillEver wonder what it is like to science consult for the entertainment industry? Read on. You may recall me mentioning in passing that I had an interesting time a while back on a sofa being interviewed by a cat, an owl, and a robot. Possibly you missed that remark, or tried to forget it!!! Well, the interview is now online, and you can enjoy it at your convenience. Embed below. The entirely spontaneous piece ended up being a humorous conversation that closely resembles a lot of serious conversations I’ve had with people trying to creatively mix science and a dramatic story (and in some depressing cases, documentary…) I try to help where I can, if I get the call in time! (Actually, to be fair, sometimes even the most bizarre creative free flow can end up being useful!)

The show is called Love Me Cat, and was created by Eric Kaplan, who does the voice of the cat, in collaboration with My Damn Channel. You’ll certainly know Eric’s work from things like Futurama and Big Bang Theory, for starters. I had a lot of fun on the show, and it was great to meet Eric, and all the

Sunday Fruit

sunday_fruit_10_Nov_2013_smallSunday saw me spend a bit of relaxing time in the morning at a breakfast bar sketching a colourful pan of tomatoes, apples, and a yellow pepper. I spend ten minutes doing a quick pen and ink outline sketch of all the elements, which was fun and pleasingly simple enough.

But then I decided to lay on some colour and so pulled the sketch into Brushes on […] Click to continue reading this post

Ten Things…

black_hole_phil_club_talkSo I’ve been a bit quiet as I’ve had a lot going on. This includes preparing ten interesting slides to use as props for a talk I gave this evening to the USC Philosophy Club. It was entitled “Ten Things YOU Should Know About Black Holes”. It started with the original idea by Michell in 1783 (yes, really, that early!) and ended with topics of current research (what is the fate of the singularity? What really happens at a horizon? Etc., etc…) I spoke for a while and then fielded tons of questions, and am now (I am writing a draft of this on the subway train home – uploading later) suffering from a rather broken voice due to too much talking and projection…. Gosh. But it was fun. A really […] Click to continue reading this post

Fail Lab Episode 8 – Testicles

fail_lab_ep_8_stillHere’s the next episode in the excellent web series Fail Lab, on Discovery’s Test Tube Channel. It’s all about testicles. Clearly no more motivation is needed to encourage you to watch. It’s in a slightly different style than the previous ones… An amusing format change, in fact. Of course, there’s still amusing shenanigans going on in the lab…

Late Arrivals

20131103-074202.jpgThe garden is quite dormant right now, after a busy Summer. But not as dormant as I thought. I spotted these a week ago, to my surprise, and gave them a bit of extra time. Today, I harvested them, mostly because they are close enough to ready, partly because Fluffy is very active in all trees outside, gathering Fall finds, and anything round seems fair game for being picked, and then mostly discarded. (Because of a fortuitous alliance with Flitty, which can raid my traps for nuts without being caught, annoyingly, Fluffy is difficult to control right now.)

Anyway. A pleasant arrival in the kitchen…

KRKD Downtown LA

It has been a long and tiring week so far and I decided that I needed to withdraw for a little while. So I left campus early and went on a wander downtown. My goal? It is the last day of the worldwide Big Draw month of October (but see below*) aimed at raising awareness of drawing (you may have seen events in your own town – maybe even participated in some), and I’ve been so busy I’ve not done much outdoor on-location drawing this month (not counting subway drawing) and so I thought that I’d get one in on the last day. My own little contribution to the local Big Draw LA, if you will.

Anyway, I considered doing some well-celebrated landmark like one so many of the splendid buildings available (Union Station, Central Library, Eastern Building, Walt Disney Concert Hall…), and as I walked I pointed myself in the direction of some of these, but just after I turned away from the library on Fifth, heading to Pershing square, I saw what I wanted to draw.

Fail Lab Episode 7: Tribalism

fail_lab_ep_7_still

Fail Lab, the web series on Discovery’s TestTube channel that I’ve been telling you about, is growing in popularity. People are hearing about its unusual charms as an edgy, funny, quirky, smart vehicle for some food for thought and are going to see. That’s great. There was a review on VideoInk today that seems to “get” series creator Patrick Scott’s “Zoochosis” point of view that informs his particular style of filmmaking, and that was good to see (although I don’t agree that the hard science can get lost sometimes – this is the online world where the viewer can take charge – if you miss an idea, just scroll back and watch it again. That creates opportunity for density in making intelligent programs, and hopefully steers us away from shallow, lowest-common-denominator programming).

Anyway, episode seven is now up, and fueled by a remarkable video it delves into ideas about how we relate to each other, within and without social groups. Here’s the embed: […] Click to continue reading this post

Big History is Coming!

big_history_promo_still

You’ll recall that I was in New York a short while ago to film some promotional material for a new TV series. It is called Big History, and it will be on History Channel’s H2 channel (and eventually on various international channels, but I’ve no idea which – similar ones to where you find the other show I’ve mentioned a bit, The Universe, I expect).

Rather than be primarily about astronomical and cosmological things, the show will focus each week on one of a list specific items that have affected our history, and take the long view about that item. How long a view? The longest known possible! So take something like Salt, and examine its role in civilization and culture, bringing in historians, anthropologists, etc… and physical scientists to trace that object back to its roots in the early universe… (the big bang, the cores of stars, etc.) Update: For you Breaking Bad fans, note that it’ll be narrated by Bryan Cranston, by the way.

Here’s one of the promo videos:

Seminar Done

seminar_over Managed to find a little time over the last few days to lay out, draw, and ink a page in The Project. It has been insanely busy for me, so this is a little bit of a triumph in stealing some time back. It’s actually the same seminar that you saw in earlier posts (here and here). Now it is over. It remains a tradition in our field to give a little round of applause after a talk, which I find rather nice and quaint. It was a pleasure to depict that.

It is a wider view of the room, which meant (aaaargh!) drawing even more faces and bodies than before. Then there’s the challenge of doing them in different states of attention, applauding, with different faces, bodies, states of dress, etc. When I come to paint it I’ll be wanting to pick colors that together communicate the right mood for the panel and for the whole page it is part of, and so forth. It can be daunting to do all those faces, bodies, shirts, feet, and […] Click to continue reading this post

Weinberg on Physics Now

I just spotted (a bit late) that Steven Weinberg (one of the giants of my field) has written a piece in the New York Review ofBooks entitled “Physics: What We Do and Don’t Know”. I recommend it. He talks about astronomy, cosmology, particle physics, and by casting his eye over the arc of their recent (intertwined) histories of ideas, experiments and discoveries, tries to put the Standard Models of particle physics and of cosmology into perspective.
