Big Draw LA

Big_draw_la_11th_october_2014_1_smallThe Big Draw LA event downtown today (in Grand Park) was a lot of fun! There were all sort of stations of activity, and lots of people were jointing in with drawing in various media, including making masks (so drawings and cut-outs) and making drawings on the concrete plaza area using strips of tape, which I thought was rather clever. (I forgot to photograph any of those, but look on twitter – and I presume instagram – under #thebigdrawla for things people have been posting.) One of the most interesting things was the construction made of drawings that people did on pieces of slate that lock together to make a larger structure. Have a look in the pictures below (click thumbnails for larger views). There were several, but maybe still not enough adults involved, in my opinion (at least when I went by). Perhaps this was due to a “I can’t draw and it is too late for me, but there is hope for the children” line of reasoning? Bad reasoning – everyone can draw! Join in, all ages. There are events all around the city (see links below).

On the Road, with Whiskey…

I’m on the road. I gave a seminar at the University of Michigan yesterday, and spent the working day chatting with various physicists at the department there, exchanging ideas, catching up on what people are up to, etc. The seminar itself went ok. I’ve been talking about extended gravitational thermodynamics, the subject of all my papers so far this year. I think I paced things a bit poorly (trying to squeeze in results from two papers while at the same time being pedagogical about the basic material since it is not familiar to most), so had to rush at the end, but I got the main points in. Lots of good questions.

At the end of the day, I was pleasantly surprised by the offer of whiskey in the break room. Apparently it is a Friday tradition. I began to wonder, and made some inquiries and found out to my delight that it is a direct decendant of a tradition that I (co-) started back in the mid-90s in Santa Barbara!

CicLAvia Tomorrow!

imageThere is a CicLAvia tomorrow*! I’m out of town right now (see next post) but I hope to make it back in time to enable me to go along at least for a little while. It looks like a fun route (see snap of map to left; click to enlarge), although it will be quite hot, so if you go, take it easy. The website is here, and you can find more information (like the 9-4 time) and so forth.

Enjoy!

Save “Krulwich Wonders”!

As readers of this blog who appreciate the idea of putting science into the daily routine for a balanced diet, of mixing in sketches here and there, of good humour and a wondering eye on the world…. you’ll agree with me that we need to raise our voices and call out to NPR to Save “Krulwich Wonders”. According to Robert Krulwich, they are planning to cancel his blog as part of cost-cutting… this would be a big blow for the (always in danger) mission to improve the public understanding of science. Many suggestions are in the comments to that post I liked above, so feel free to read them and follow the ones that make sense to you! [Update: I’ve put a hashtag #savewonderNPR into the accompanying tweet of this post, so feel free to use that in your own raising awareness efforts on this…]

Act fast to let your voice be heard. The axe is on its way down!*

Pot Luck

pot_luck_25_04_14_6Here in Aspen there was a pleasant party over at the apartment of one of the visiting physicists this evening. I know it seems odd, but it has been a while since I’ve been at a party with a lot of physicists (I’m not counting the official dinners at the Strings conference a fews weeks back), and I enjoyed it. I heard a little about what some old friends were up to, and met some spouses and learned what they do, and so forth. For the first time, I think, I spoke at length to some curious physicists about the graphic book project, and the associated frustrating adventures in the publishing world (short version: most people love it, but they just don’t want to take a risk on an unusual project…), and they were excited about it, which was nice of them.

pot_luck_25_04_14_1It was a pot luck, and so although I was thinking I’d be tired and just take along a six-pack of beer, by lunchtime I decided that I’d make a little something and take it along. Then, as I tend to do, it became two little somethings…and I went and bought the ingredients at the supermarket nearby and worked down at the centre until later. Well, first I made a simple syrup from sugar and water and muddled and worried a lot of tarragon into it.

pot_luck_25_04_14_2 Then in the evening, there was a lot of peeling and chopping. This is usually one of my favourite things, but the knives in the apartment I am staying in are as blunt as sticks of warm butter, and so chopping was long and fretful. (And dangerous… don’t people realise that blunt knives are actually more dangerous than sharp ones?) […] Click to continue reading this post

Fireworks!

It is the 4th of July, and I hope you who are celebrating it have a good time today!
fail_lab_ep_6_still_2

I can’t really let the day pass without sharing with you the episode of Fail Lab in which we examine fireworks and pyrotechnics with an appropriate cautionary note, and a dash of humour. Enjoy it again if you’ve seen it before, and don’t forget to check out all twelve episodes. You can read my discussion of the whole series (excellently made by Patrick Scott) starting here, and there’s more here. Click below for the episode: […] Click to continue reading this post

Honest Time Travel?

On Tuesday I hung out with some of the Screen Junkies folks who you may know from the hilarious “Honest Movie Trailers” web series (seriously, if you’ve not seen any of them, please go right now and have a look). We had a fun chat about time travel in movies, and presenter Hal Rudnick and I bonded over various movies old and new. The final version of the show is up on YouTube (embed below), and I’m bummed that I did not get to meet the other guest, Christina Heinlein (JPL), who seems fun – and is a descendant of, yes, that Heinlein. I love the idea that she works at JPL, helping make possible the space exploration that Robert Heinlein helped inspire us all about in his writing. Anyway, enjoy the short piece (I wish you could see a bunch of the other material too… we really had a great chat about the ins and outs of time travel, but a lot of it inevitably ended up not making the cut…)

I could not resist talking about my view of this (perhaps growing) trend of using time travel as a means of resetting movie franchises (see Star Trek, X-Men…). It’s a great way of repairing writing and other filmmaking wrong turns. Feel free to imagine your own version of this – Star Wars anyone? Another pass at […] Click to continue reading this post

Commencement Capers…

bromptons_and_robesIt is Commencement day today at USC! In celebration of that I thought I’d post a picture of my colleague Krzysztof Pilch and I, being a bit silly. We each have one of those excellently practical Brompton bikes (splendidly finished in British racing green, of course) you sometimes have read about here, and Krzysztof suggested that we take a picture or two of us in academic robes riding our bikes. Krzysztof had his academic full gear ready because […] Click to continue reading this post

Debate about Forever…

This is a good one from the Onion. (I’ve not looked in on them for a while, so this was a funny thing to return to see…*) The title says it all: “Top Theoretical Physicists, R&B Singers Meet To Debate Meaning Of Forever”. Extract:

[…] at the four-day symposium, where they grappled with extant questions regarding the concept of forever that remained unresolved, such as whether forever is better conceived as an infinite, four-dimensional expanse of space-time or, rather, what one second feels like when you’re away from your girl.

“For many years, the R&B community has posited the classic notion that forever is presumed to go on and on like our love,” said Edward Witten, a string theorist at the Institute for Advanced Study, who acknowledged that while time appears to extend unendingly, it is paradoxically composed of discrete moments such as a tender embrace or a single perfect kiss. “This assertion then raises a problem of even greater […]

Science Films Galore!

Sorry that it has taken me so long to get to posting the results of the USC Science Film Competition. It has been super-hectic. In addition to the usual things I have to do, I had to give a talk about science education to the Society of Physics Students – that went well, I heard – read and examine another PhD. thesis (twice in one week), do battle with two fronts of vermin attacks on my house, and prep a whole lot of other things I won’t trouble you with… Also, oddly, the time change seems to have left me in a state of exhaustion each day.

Enough with the excuses. What are the results, you ask? And is it true the winner was controversial?!

usc_science_film_showcase_2014_1Well, first and foremost we had a fantastic time celebrating the work of all the students in the competition. About 75 or so people turned up, making all my frantic buying of things in Trader Joe’s and so forth all worth while, and there were two screening sessions separated by a coffee and snacks break. Since there were twelve films this year (a 50% increase!) there were six per session (I curated things so that the sessions were about the same length), which worked rather well. A lot of the films used quite a bit of their 10 minute allowed duration, and so given that I pause between films to give each team a chance to take a bow, it was in danger of being a long evening, and for that I apologize to everyone, but I do think that the students should get a fair amount of individual recognition for their hard work.

Anyway, to cut a long story to medium, the standard was quite high this year, with several good films at the top that were hard to choose between, but I think the 15 judges (from academia and the film industry, with scientists and filmmakers and scientists-turned-filmmakers on both sides) got it right.

The first prize winning film has resulted in raised eyebrows from some, including the filmmakers themselves who apparently were sure that their film would be overlooked due to its content. I think that the judges got it exactly right. It is a fine example of exactly what I’m looking for in this competition- a […] Click to continue reading this post

Showcase and Awards Today!

science_film_competition_logo_smallJust a reminder: The USC Science Film Competition Showcase and Awards are tonight (March 7th) at 6:00pm. I’ve been tallying up all the judges’ input and have the results in special envelopes to give out tonight. Very exciting. Come along (event information here), and enjoy celebrating all the students’ hard work. There will be twelve films on display!

Festival of Joe

20140226-214941.jpgEarly evening. Cocktail (made with Hendricks gin, muddled tangerine, and basil…). Roast pork on the way. Old haunt.

Where am I? At Roy’s, in Santa Barbara. I’m here for a two day celebration of the work of Joe Polchinski, one of the giants of my field. It all begins tomorrow, and I am taking the opportunity to have a quiet bit of time in an old haunt. I was a postdoc of Joe’s back in the mid 1990s, just when the world of theoretical physics was waking up to the awesome power of D-branes. D-branes are a special type of dynamical extended object in physics, and Joe had discovered their importance for string theory just around that time. Roy’s opened around that time too, if I recall, and a group of us became regulars, helping it along in those early days when it was smaller than it is now. (That small group included my friend and fellow postdoc Andrew Chamblin, who passed away some years ago.)

A D-braneSo I am here to help celebrate Joe’s work on the occasion of his 60th (hard to believe that number, frankly), and it will be good to see all the people who show up, and of course it’ll be excellent to see Joe. Part of my help in the celebrations is to organize and run a panel about D-branes, which will be on at 11:00 tomorrow. I’ll be reflecting a bit on the good old days when D-branes really broke, and turned out to be the key tool of the Revolution that took place in the field. In lectures and writings from that time and long after I used to refer to them as the Heroes of the Revolution, and in honor of that and of Joe I have named this session D-Branes, Tools of the Revolutionary, or something like that. Joe helped bring about the revolution, and his tools were D-branes, you see.

I was lucky to be here as a postdoc at that time, and happily I had the good sense to be quite sure that it was going to be important to quickly spread the […] Click to continue reading this post

Frozen – Not the Movie

beth_gilmore_bubblesI liked the piece on Morning Edition this morning about the experiments people were doing with the extreme cold in parts of the country, including making clouds, and seeing what happens to soap bubbles when they freeze!

The piece is here, and the “storify” box with some photos and videos is here. (The photo to the right -of frozen soap bubbles!- is by Beth Gilmore and I found it there.)

New Year Renewal

renewal_bike_standHappy New Year, to all readers of Asymptotia!

I bought myself a treat for the new year, after much deliberation and hesitation. I hesitated because it is not something I needed, but definitely something that would improve things a bit. It is a stand at which to do repairs and general maintenance on the bike. I really don’t like fiddling with things like adjusting gears, changing and balancing wheels, and so forth when the bike is on the ground. You have to wrestle with it a bit as it squirms around, and for a long, subtle task (like adjusting gear shifts and so forth as I had to do recently), it can be tiring on the back too. So I bought a nice stable stand (pictured*), and […] Click to continue reading this post
