Talking about gauge invariance took a couple more pages than I planned…
Well, this conversation (for the book) takes place in a (famous) railway station, so it would be neglectful of me to not have people scurrying around and so forth. I can’t do too many of these… takes a long time to draw all that detail, then put in shadows, then paint, etc. Drawing directly on screen saves time (cutting out scanning, adjusting the scan, etc), but still…
This is a screen shot (literally, sort of – I just pointed a camera at it) of a detailed large panel in progress. I got bored doing the […] Click to continue reading this post
(Well, not really oops… It’s deliberate.) LIGO has announced another gravitational wave detection from a black hole merger! This time the black holes were 14.2 and 7.5 times the mass of the sun, and merged to form a new black hole of mass 20.8 times the mass of our sun, releasing a burst of energy […] Click to continue reading this post
Stephanie DeMarco interviewed me a few weeks ago for an article she was writing about the science in the TV show Agent Carter (season two). As you know, I did a lot of work for them on the science, some of which I’ve mentioned here, and we spoke about some of that and a lot of interesting other things besides. Well, her article appeared in Signal to Noise magazine, a publication all about communicating science, and it’s really a nice piece. You can read it here. (The excellent title I used for this post is from her article.)
It is a pity that the show has not been renewed for a third season (I’m trying not […] Click to continue reading this post
This year’s USC Science Film Competition saw another crop of films with a great variety of approaches, with live action and animation, comedy, drama and documentary, and all sorts of hydrids of those forms. Thanks to all who took part. As for the results, and seeing the films (do take a look!) I’ll repeat here the post I did over on the competition’s blog:
We had a lot of fun at the screening and showcase last Thursday. The films looked great on the Imax screen. Many thanks to Matt Scott for working hard to make sure it all looked great, and also to him and the Large Format Cinema Club for co-hosting the event! Once again, thanks to the Burg Foundation for supporting the competition financially with prize money, grants for helping with the filmmaking, and funds for refreshments and logistics.
The results are as follows: […] Click to continue reading this post
For the first time in its history, the Southern California Strings Seminar was held in Santa Barbara, at the KITP! It was probably the largest meeting that has been held under that banner, with attendance from all over the map of theory groups in the region. Thanks for Edgar Shaghoulian for organising it!
Although I was a bit under the weather (never really figured out what the matter was) and super-pressed for time, I went along to support it and learn a bit about what was going on. I think that there’ll be a posting on the KITP’s online talks website at some point with the various talks, so you can look in too (keep an eye on their website).
I did not fancy driving there and playing dodgems with the traffic and so -as seems to be my custom when [….] Click to continue reading this post
This month’s issue of Physics Today has a review that I wrote of the book “Quantum Field Theory for the Gifted Amateur”, by Tom Lancaster and Stephen J. Blundell. I took the opportunity to give a broader view (albeit brief, given the word limit) of the landscape of books on that subject and how it has changed a lot, in a way that I think reflects some excellent changes in formal theory brought about by (at least in part) research into the many topics pulled together under the broad umbrella of string theory. As you might know from reading here and elsewhere, I’ve long been pushing for the increased application of the ideas and techniques of string theory to other areas of physics, and it has become quite the thing these days, I’m happy to see. Such research has resulted in the blurring of the […] Click to continue reading this post
(Yeah, the headline. Seems you can’t have a story about science connecting with the rest of the culture without the word “nerd” being used somewhere…)
Well, that was a fun event. Here’s a photograph* of Sean Carroll and me as guests of the always-excellent host Patt Morrison at the Natural History Museum as we talk about aspects of the science of space (and time) as it appears in the movies, how we go about giving advice to filmmakers, and so forth. It was part of the First Fridays series which has a special focus on […] Click to continue reading this post
Extract from Wednesday’s General Relativity class:
Me, at the board writing equations: “…and so the ratio of the earth’s radius to its radius of gyration is about 0.577…”
Student raises hand and asks: “What’s radius of gyration?”
Me: “Er… It’s the average spacing everyone has to give you at the night club when you go Ker-ray-zay on the dance floor.”
As luck would have it, everyone laughed. That would have been a terrible time to have an awkward silence.
I’ll be on a panel about science (particularly space-related) and the movies, with fellow panelist Sean Carroll, and it is hosted by the awesome Patt Morrison! It’s part of the Natural History Museum’s First Fridays series, which you might recall me blogging about here before (actually, last time I was at one, I was a host so I imagine it’ll feel a bit different this time).
Here’s a website with all the details.
Apparently I was on an episode of the BBC program Horizon a couple of hours ago over in the UK. I completely forgot that was coming up and forgot to mention it. Sorry! I’ve no idea what parts of the interview with me they used, or what the final thrust of the episode is, but I did have a lot of fun shooting the episode with the filmmakers over in Joshua Tree some time last year. See a post I did about it here. I spent some time explaining why negative mass is problematic, especially in the context of gravity… The program talks a lot about people who are trying to find anti-gravity of various sorts. I was reminded that the episode aired since I found myself tagged on social media, and wondered what the ruckus was about. Then I found the following tweet by @homeworkjunkie with a screen shot, and the caption “Nice reaction to runaway problem;zero cost energy proposed by some people in BBC Horizon”:

Well, today’s hunt for a print copy of the New York Times (click for larger view) was easier than the Wall Street Journal hunt a couple of months back. Been a while since I was in the Science Times, and I’ve not been in it in this capacity before. The Simons Fellowship announcement was today, and I was awarded one. I’m honoured to be in such fine company! Nice to see my friends Lawrence Hall, Jeff Harvey, Petr Horava, Andy Strominger among my fellow Fellows, and congratulations to everyone!
This is a major part of my sabbatical planning for next academic year (half book-completing, half research), and it sure is great to get it. There aren’t many fellowships of this sort for my area of work. Thanks Simons Foundation and all concerned.
*And when I say fulfilled… Well, there’s still the matter of actually doing the thing and getting all my planning to work out… Click to continue reading this post
