Breakfast Guy

I’ve no idea who he was, but he made for an interesting subject for several minutes*, sitting eating his breakfast with his (I think) wife. I was staying at a hotel and having breakfast, just North of Santa Barbara. The person I set out wanting to draw (very interesting face) was sitting right opposite me, at the same table as me, looking over regularly, and so it seemed a bad idea to try to sketch him. Also, he turned out to be a physicist also visiting at the KITP for a workshop, and so it could have ended up quite awkward.

It was a pretty good week at the workshop. I had a number of interesting conversations with young people trying out ideas and calculations, who’ve actually read (!) various papers of mine, and so had questions and […] Click to continue reading this post →

Science Film Connections

So journalist Pamela Johnson (no relation!) did a nice article last week about the science+film competition I mentioned to you (see also here). It is entitled “It Could Happen One Night”, and you can take a look at it here.

If you’re a student at USC and thinking that you can’t do this because you don’t know about science, or you don’t know about film… don’t give up! You might just need help to figure out how to get in contact with students who also want to get involved in making a film and want to learn more about one side or another (so you’re in the […] Click to continue reading this post →

No. Uh-uh. Nope. Nuh-Uh.

I’ve received any number of emails from excited friends pointing me to articles in the news saying that particles have been discovered moving faster than the speed of light. Thanks everyone! My initial gut-response to the whole thing has been as given in the title of this post. My measured, scientist-response has been “this is extremely unlikely”. You see, it doesn’t seem to make much sense to me at all, and I expect that the scientists involved will at some point find an error, or other scientists will fail to reproduce the experiment. But, let’s see what happens. The great thing about science is that it is not about what people believe. It is about demonstrating phenomena with reliable, repeatable experiments. (The experiments were done by the OPERA collaboration, and their preliminary paper is here. I don’t need to point to the news articles since every news outlet has a bit on it.)

It’s funny, I’ve recently been writing about this in a part of the graphic novel. Somehow I think that the speed of light is presented too much as a speed limit in popular discourse, and so people naturally keep thinking that there’s some way of violating the law, like you can on the highway, or that some things are not subject to that law, like motorcycle cops, or people in a hurry to get home to watch Madmen, etc… I don’t expect this to be terribly clear in the short time I have to type this between this and that, but I think things are better thought of not in terms of a speed limit, but rather in terms of the fact that it all has to do with the meaning of what space and […] Click to continue reading this post →

Categorically Not! – Food

Comments Off on Categorically Not! – Food

The new season of Categorically Not! gatherings started last Sunday night. It went very well. You may recall that it is held at the Santa Monica Art Studios. It’s a series – started and run by science writer K. C. Cole – of fun and informative conversations deliberately ignoring the traditional boundaries between art, science, humanities, and other subjects. Here is the website that describes past ones, and upcoming ones.

This one was about food, and had musings on food and bringing people together at New York’s Cornelia Street Cafe, by the founder Robin Hirsch. He talked about the history of the place, read some extract from his writings about it, and also described the beginnings of the “Entertaining Science” series that got going when K C Cole, Roald Hoffman, and Oliver Sacks did a performance there many years ago. The Categorically Not! series, now five years or so in age, was a spiritual outgrowth of that series, and so it was great to see Robin speak at it. He was very pleasant and interesting to talk to before and after the event too. (I did a quick, rough, sketch during his 20 minute segment – with some tidying up later – and have included it for you to see. Click for slightly larger view.)

Robin was followed by Amy Rowat, of UCLA. Amy gave us a nice overview of what’s going on in her lab. She’s a physicist, and spends a lot of her time looking at food through that lens. The concerns she described were largely ones of structural, […] Click to continue reading this post →

Journeying

It is 8:20am, and only now is the sun appearing from behind the mist that seemed to cover the world since I got up this morning at 6:00am and since I boarded the Amtrak train at 7:30am, bound for Santa Barbara. We’ve arrived at beautiful downtown Northridge, and have another two hours and a half to go. I’ve got my bike folded neatly in the luggage rack above me (I tried not to look too smug when passing two cyclists struggling a bit to find room for their giant bikes in the space remaining to them), have had my second slice of multigrain bread smeared with whipped cream cheese and homemade fig jam (I made a batch a few weeks ago) and an sipping coffee while catching up on various things, such as telling you what I am doing. I think I’ll stop writing for the blog now, getting back to thinking about some physics I want to put into a new paper, looking out the window at the landscape as it opens up more (we’ll be running through farmland, and then along the seaside soon!), and letting my mind drift and be open to those expansive kinds of thoughts that typically come in when I am sitting on a train watching the world go by. I don’t get that with driving up here, since so much it put into driving safely and so forth, one’s mind is never fully free. I love train travel, and I love this journey, even though I know there’s no good reason why in the 21st Century in the USA it should take three hours. (Three and a half on the return – I mean, really).

Ok… back to stuff.

Oh, wait – Why am I going to Santa Barbara, you ask? Is it another “jump on the train and see where I end up” sort of day? (See an earlier post.) No, I’m going up there (actually my stop is Goleta) to spend a bit of the week at[…] Click to continue reading this post →

That Was the Week that Was

I might be losing my stamina, or have simply taken on more than I usually do, but it sure seems more tiring and hectic than it usually does this early in the semester.

It was a busy week, but I managed to get a few things done here and there that seem worthwhile, so I count my blessings, as they say. (Or used to say – maybe that’s somehow too loaded a phrase to use now? Not sure.)

To attempt to wind down yesterday after a tightly wound day and found myself walking with large sketchbook in hand in the warm evening sunlight to a studio to […] Click to continue reading this post →

Spin

This week marks a landmark in the class (Introduction to Quantum Field Theory) since it focuses on the seminal work of one my heroes, Paul Dirac, who quietly went about his business of puzzling over the issue of how to find an equation that describes the properties of electrons (particles of spin one-half), and in finding what is now called the Dirac equation (see snapshot from my notes on right), uncovered a hugely rich and bright cornerstone of fundamental physics. It is famously described as a sort of square root of the relativistic wave equation known at the time – the Klein-Gordon equation – and in that way of thinking you quickly arrive at the idea of anti-particles (as did Dirac), since taking a square root leads to two solutions (both +2 and -2 square to give you 4). One solution turned out to be the electron, and the other leads (by an appropriate path of reasoning) to its anti-particle, the positron*.

Besides leading inevitably to anti-particles, the equation (which Dirac pursued in […] Click to continue reading this post →

Reaching Out

So I’ve been spending a huge amount of time trying to generate awareness among the students and faculty about the newly launched film competition. I don’t know how much traction I’m getting, but we shall see. Lots of poster posting, and giving packets of postcards to colleagues in College departments such as Physics, Chemistry, and the Writing Program, and over in Annenberg School for Communications and Journalism, and of course the Cinematic Arts School. I need to figure out a way of getting a foothold over in the various areas of the Keck School of Medicine, on the other campus… It’s open to all students at USC, but I need to make sure I target certain concentrations to maximize chances of getting interested students’ attention.

On Monday I did an interview with a student reporter for the Daily Trojan and that appeared this morning. (Have a read.) I’m a bit embarrassed that they missed out mentioning my colleague and collaborator Anna Krylov, but the main thing is that more people will learn about the initiative though the article. It was fun talking to Jasmine, the reporter. The key thing, for me, is that the collaborative aspect of all of this is forefront, since that’s the most important aspect. As I said in an email to another reporter this morning (which may or may not result in an article, we shall see): […] Click to continue reading this post →

From C to Zee

End of the first week of semester. I’m already tired, I must confess. I think it is mostly a combination of running around doing various things for various projects including another big shoot this week for the science documentary series, and prepping all the publicity for the science film competition, which is now rolling along and gathering momentum, and through it all… the heat. It is just so very hot, and not using air conditioning much and walking and cycling in it to boot does mean that I’m tiring out a bit more. I’ve been waking up with those low level headaches from time to time that signal that I’ve not been cool enough during my sleep, despite having several windows open for throughput. Might have to give up and cool things down a bit with the air conditioning on a thermostat setting of some sort.

So through all that, (and not counting other things like steady progress with a research project, and the drawing here and there that I’ve told you about… oh! and the garden) I’ve also been teaching a course. It is on introductory quantum field […] Click to continue reading this post →

Announcing: Science Films USC!

By | | , , , , , ,

Ok, so here is the announcement I promised last week. Science Films USC! It is a film-making competition! The first of its kind at USC, I think. Right now, all there is to say is that we welcome teams of USC students from Cinematic Arts, Communications, Science, Engineering, and beyond, to enter the competition. They will present a short film that explains and/or illustrates a scientific concept, principle, or issue, for a wide non-expert audience. The first prize will be $2500. Yes, we are giving a serious prize for what we hope will be a serious competition with some wonderful entries. We’ll have a film festival in January, some prize-giving, and maybe some interesting people connected with the film world at the award ceremony. Of course, we’ll have it early in the award season, in January.

You can learn more at sciencefilms.usc.edu and for those of you who can’t bear to be away from facebook for long, also at facebook.com/sciencefilmsusc.

By August 31st, we will announce the details of the eligibility requirements, rules, and opportunities for those who are not well-resourced to get a small grant to help out with developing their film.

Teams, said I? Yes. As you know from many of my posts here and the work I’ve done in the past, I think that the future of better presentations of science in the media and entertainment, etc, is to get communicators and scientists working together and […] Click to continue reading this post →

Crazy Week…

Feels like a crazy week so far. Not sure why. I’m sort of recovering from a bamboozling amount of sunlight yesterday, so maybe I’m a bit addled in the head, compromising perspective. I was up in the brown hills somewhat North of LA on an old disused airstrip, shooting a very interesting segment for a TV show. I’ll tell you more later, but it involved being in the unforgivingly intense sunlight from 10:00am to 6:00pm… with only my hat to protect me between takes… long, sunbaked, takes. I’ll tell you more a bit later. It was very worthwhile. The whole thing is what can definitely be thought of as a great “teaching moment” which will be lovingly done in HD, and well-edited and so forth. More later.

Had to find some time today to email and chat with a couple of other writer directors for two other TV episodes that will appear. I was trying to get an idea of what science story they are trying to tell and help shape the kinds of questions and answers we might be able to explore in the (minor) contribution I’ll make to their shows. Tomorrow morning I will have to make myself presentable again in order to discuss the material on camera… one a 3D HD show, the other just garden variety HD. We’ll shoot until well after lunch, and then hopefully I can get back to other projects for the rest of the day once that has done. I’m behind on a number of things.

I’m supposed to be able to point you to the websites where we announce the […] Click to continue reading this post →

Multiverse Musings

As you may know already there’ll be a new NOVA series on PBS in the Fall, based on one of Brian Greene’s books, The Fabric of the Cosmos. Last Fall I did some a shoot with them for my role in it (I’ve no idea how much they will use), and I learned a short while ago that they’ll be using some of it on the NOVA website too. They extracted some parts of the on-camera interview segments I did concerning the idea of multiple universes and transcribed them into something you can read online. Have a look here. I touch on the idea in a fragmented way, mostly being led by the questions I was asked, but it’s a fun topic to chat about, and may lead you in interesting directions should you wish to learn more, so have a look.

A word on the picture they are using (er…see above left). It seems to be one that the […] Click to continue reading this post →

So, here’s yet another project I’ve been working on. I forgot to tell you about it. After the success of the short films I produced and directed (etc) two Summers ago (remember? Shine a Light and Laser), the next step was to get more people involved in the film-making, to learn more about how it is done, and what is involved, both on the science side and the film-making side. Specifically, I want students from both sides of the divide (science, and film, journalism, communications, etc) to have to work with each other to learn more about communicating science.

So, Anna Krylov (Chemistry dept., and a collaborator on an NSF grant) and I wrote a […] Click to continue reading this post →

Heretic…?

We had a really interesting discussion of the quantum physics of de Sitter spacetime yesterday here in Aspen, starting with a review of the behaviour of scalar fields in such a background, led by Don Marolf, and then, after lunch, an open-ended discussion led by Steve Shenker. This is all quite difficult, and is of course quite relevant, since a piece of de Sitter is relevant to discussions of inflation, which seems (from cosmological observations) to have been a dominant phase of the very early universe. As the most symmetric space with positive cosmological constant, de Sitter may also be relevant to the universe today, since dark energy (first recognized after 1998’s observations of the universe’s accelerating expansion) may well accounted for by a positive cosmological constant.

So we need to understand this type of spacetime really well… and it seems that we don’t. Now there’ve been a lot of people looking at all this and doing really excellent work, and they understand various issues really well – I am not one of them, as I’ve not worked on this in any detail as yet. Do look at the papers of Marolf, and of Shenker, and collaborators, and references therein, and catch up with what’s been going on in your own way. For what it is worth, the sense that I get is that we’re trying to solve very difficult issues of how to interpret various quantum features of the spacetime and getting a lot of puzzles by trying to make it look a lot like things we’ve done before.

Now, we may solve all these puzzles…. but my current take on this all is that we’re […] Click to continue reading this post →

On Physics, Spiritualism, Fiction, and Non-Fiction

On Monday evening I chatted with Deborah Cloyed, author of the recently released novel “The Summer We Came to Life”, which I finished reading over the weekend. The conversation was recorded for Rare Bird Literature’s Rare Bird Radio site, and so you can listen. (Embed at the end of this post.) We talked about her use of various physics ideas (Copenhagen and Many Worlds quantum mechanics interpretations, parallel worlds) in her skillfully crafted novel about four friends, loss, the afterlife, and friendship.

At this point, some of you are yelling “Run, run for your life, Mr. Scientist!”. But No. No, no, no. I think that’s a mistake. Deborah is, first of all, writing a novel, not trying to push some self-help book that cherry picks a few ideas from science, conflates them with some stuff people want to hear, and trying to make a buck out of it. Second of all, she really loves the science, and seems to have read a lot about the subject, unusually widely. You don’t ignore someone who really cares about the subject and wants to know more, especially when they want to include it in the work they are producing. So when we were introduced a while back, she thought it would be fun and interesting to have a conversation about various things, and I agreed. I got the chance to comment (at her request) about what I thought she was doing with the science, and how the final result worked, I got to ask her what she thought of it, and from there we talked about lots of related topics, including the whole idea of mixing […] Click to continue reading this post →
