british_library_1Well, it has been quite the week so far. I’ve been mostly in England. First I spent Tuesday getting over the main effects of jetlag and a short but strong cold (both more or less gone now), and then Wednesday I went to King’s College London to give a seminar to the three groups in the Triangle series of seminars – King’s, Imperial, Queen Mary are the three places the participating research groups in theoretical high energy physics come from. It was excellent to see so many old friends and colleagues, meet some new ones, and chat physics at the pub and over dinner later on. The seminar seemed to be well received, although I know I was far from my best, given jetlag and cold. The next two days saw me saying hi to family and friends at coffee and dinner in the evenings and visiting at Queen Mary and Imperial for the day, and hiding in the British Library for most of Friday, writing.

What am I writing? Four lectures on D-branes and string theory and M-theory, with a focus on some of the fun and instructive applications (and potential applications) of Click to continue reading this post →

rocking_chairsI had a lot of time to kill in Philadelphia’s International Airport on Sunday (I was changing planes), and I must say that is not a bad airport in which to be in such a situation. I like the city a lot, and so am not surprised that its main airport is to my liking. First of all, who can not like an airport that supplies you with… (you’re expecting free wireless, and they had that, sure, but no, I mean)… with… Rocking Chairs!!!

I saw some excellent art as well. And lots of displays of various types. I’ll share a couple more in a post or two, but look at some of the pieces I snapped pictures of for you. They are done with packing tape! Yes, packing tape. That brown thin stuff you know well… It was part of a series of scenes from noir films, rendered in this way. Very effective indeed, I felt. The series name is “Tape Noir”.

Comments Off on Market Matters

As you may know from earlier posts, I love markets, a place where people come together with lots to see, talk about, interact over, and of course to taste. Community. One of my favourite things. Here’s a lovely stall at Granville Island in Vancouver when I was there briefly a short while ago. (Click for larger view.)

The Leonids are almost here!

nasa sky mapAnother meteor shower is almost upon us. Next week it is the turn of the Leonids. Now, as the name implies, these have their apparent origin in the constellation Leo. So how visible it will be for you, if you live in an urban area, might depend upon Leo’s position in the sky relative to your local bright city lights at the time of viewing. But it is worth trying. Look for a public park, rooftop, or other open area of sky. Parks can be better for pulling you away from some of the immediate lights, and then sit still and look at one patch of sky steadily for a while (generally in the right direction!)

More Gold for Everybody!

metro_gold_celebrationI’ve learned over the years that news about public transportation often does not reach people in Los Angeles who aren’t already inclined to use it (that’s a lot of people) and so I ought not to assume that everyone’s heard about the exciting events of tomorrow. So here’s a quick post to let you know that the new Eastside extension of the Gold Line opens tomorrow! This is very exciting indeed! Spread the word! There’ll be lots of events to celebrate during the course of the day, and you can learn a lot about them at this link. You can ride the whole Gold line free to explore the system.

Those of you who will no doubt continue to insist that public transport in Los Angeles will never have anything to do with you (until there is a personal stop with a single-person train carriage right outside your home and a corresponding one wherever you want to go) can also join in the fun (just for the day, you understand) and come to the farmer’s market, see the bands and the people and so forth, and confirm your familiar position that it “won’t work for you” because it “doesn’t go anywhere”, just like the rest of the entire system supposedly doesn’t.

Soon, I’ll be doing a post on progress that has been made in recent months on the Expo line, by the way. That’ll be another celebration when that opens in late 2010 Click to continue reading this post →

Wet Moon

Aha! So you were thinking the mission last month was a bit of a failure, right? Because there was no big splash (literally) of a plume for the press to gush about? I’m talking about the October LCROSS mission on October 9th that smashed an impactor onto the moon’s surface (at the Cabeus crater) to create a cloud of dust for analysis. I remember people thinking, encouraged by various reports, that the event was rather a damp squib, since it did not produce a Hollywood-style flash and plume. See an NPR report on the mission here from back then.

lcross_dataWell, science is known for being able to carry on steadily even if there are no overt special effects and a catchy soundtrack. Today, NASA announced that their analysis of the data produced from measuring the dust cloud’s properties has shown very definite signs of water (confirming and strengthening the results accumulated by other missions (India’s Chandrayaan-1 and NASA’s Deep Impact and Cassini probes) that I Click to continue reading this post →

Help from the Bugs

Comments Off on Help from the Bugs

On NPR’s Morning Edition the other day there was an interesting piece by Nell Greenfieldboyce about a lovely piece of research on the effects of various cultures of microbial organisms in our stomachs on how we extract nutrients from food. The key point is that what lives in our stomachs and how it interacts with what we eat is a key consideration in worrying about issues like nutrition, obesity, and other issues. I recommend listening to the audio of the piece, which you can find (along with a transcript if you prefer) here. (Actually, while searching for the audio for the story I found a related story by Robert Krulwich from almost exactly a year earlier. You can listen to that here.)

The Universe: Cool Cars, Hot Sand, and Fast Balls

flows in death valleyYou may recall my mentioning a desert trip to shoot something for TV, some time back. One done at precisely the wrong time of year. And to Death Valley, one of the hottest places on earth, to boot. Well, I meant to mention that the episode of the History Channel’s The Universe that the shoot was for aired a week or two ago and it was really excellent. It was entitled “Liquid Universe” and it was a rather beautiful and thoroughly pleasant episode exploring the role of liquids in our universe, a matter not often raised in questions of astronomy except when it comes to matters of water from time to time. This was not about water per se, but rather the whole matter of material that flows and the role it plays in diverse areas of the solar system and perhaps the universe at large. I was using sand to demonstrate how sometimes there are surprising places where you can find fluid/liquid behaviour, and mentioned some of the new phases of matter found in the context, for example, of quarks and gluons at RHIC. (I’ve spoken about that here a number of times in the context of some of my research. See the archives.)

It was an excellent episode and another example of how one can take a topic under the “The Universe” heading and showcase lots of exciting science quite accessibly Click to continue reading this post →

Gloomy Sunday

vancouver_boatsDespite the title, which is also the title of an utterly depressing but wonderful song that I love, which starts out: “Sunday is gloomy/my hours are slumberless/dearest the shadows/I live with are numberless/…” and wallows in further and darker gloom for the rest of the song until near the end, I mean gloomy here in a neutral way.

It applies not to my mood but to the skies over Vancouver on the Saturday and Sunday set aside for wandering and exploring. I actually found a lot of it quite refreshing (recall that we’ve not had much rain in LA all year) and managed to see several beautiful scenes made all the more lovely for the shades of grey provided by the rain and clouds. The scene with the boats above left is an example. Overall I had a great time exploring, and was shown some nice parts of the city by my hosts, Moshe Rozali and his family (thanks guys!).

The trip was a success, in that I had a lot of great conversations with various people about physics research matters, and also in terms of the main point of the trip which Click to continue reading this post →

Slaughter at the Podium

debate_on_catholic_church1I simply insist that you take the time out to watch this video*. It is of a debate that took place on BBC television, the motion being “Is the Catholic church a force for good in the world?”. It was between Christopher Hitchens and Stephen Fry on one side (against) and Anne Widdecombe and Archbishop John Onaiyekan on the other (for). Dogma vs Reason, when it comes down to it. Now, it is one thing for the side that is in favour of the motion to be a bit lame compared to the duo they are up against, but it is really unfortunate that Anne Widdecombe was put up as the defender of the church as she has been so utterly arrogant and unpleasant in every appearance I have ever heard or seen her in, Click to continue reading this post →

dining_at_vijs_3Well, that was not altogether terrible, I gather, but I was so tired and a little bit out of sorts* when I started giving the talk that I was running very slowly. So by time I got to the end (even though I hit my right pace later on) I was some 15 minutes over. Ugh. People seemed to like it, but I definitely need to whittle out a few of the more superfluous slides (which I’d always intended to) and strike the intended pace I wanted to hit earlier than 3/4 of the way through the talk. My reward (besides some nice remarks at the end of the talk that sort of made my day) was a visit to another excellent restaurant for dinner, with some good company. The extraordinarily good Vij’s. The hour’s wait for the food was perfectly fine given the nibbles they bring you while you wait, and the food itself once you get it. Here’s a shot or two of some of the excellent food just after its arrival, and the empty dishes and satisfied hosts just after polishing it all off: Click to continue reading this post →

Remote Office

I’m in remote office mode again. I’ve to give two colloquia while visiting two physics departments in Vancouver area over the next two days. (Subject matter will be essentially the same as the one I gave a month ago.) So tonight, I’m eating dinner at the splendid restaurant Banana Leaf not far from my hotel while reviewing the slides of my presentations on my pda (my iTouch dining_at_banana_leaf– I dump lots of files I want to read on it using an application called filemagnet. Very useful. See here. In this case I’m looking at the pdf output from the keynote presentation software I use. ) I’m making a few notes on changes I’ll make when I get back to my hotel. I’m also reviewing a few other documents that were sent to me for response, and tying off various loose ends here and there before the evening ends.

I sometimes worry that it might be considered rude that I’m apparently doing a bit of work and so not fully paying attention to the food, but I’m not too worried, really. Once the actual food arrives I’ve been quite appreciative of it, giving it my full Click to continue reading this post →

Brian Cox on Colbert

brian_cox_colbertPhysicist Brian Cox had a bit of fun on Colbert a few nights back*. At Stephen Colbert’s prompting he mentions the nonsense about time travel and the Higgs boson, (which I decided not to blog since it was so frustratingly idiotic and had no business in, for example the science section of a national newspaper not the least because it just serves to confuse readers with even more nonsense about the Large Hadron Collider (LHC) than they already have been) and then has a blast (it seems) discussing the importance of Special Relativity, [tex]E=mc^2[/tex], and why you should care, which is the subject of his new book with Jeff Forshaw.

Unfortunately he seems, at one point, to fall into the usual (high-horsed physicist) pattern of dismissing another legitimate science endeavour (food science in this case) as not science, but I’ll give him the benefit of the doubt and assume it was just a joke made in the heat of the moment. He’s too smart and likeable a guy, (and a very good public spokesperson for science education by all accounts and past appearances), to be quite so dismissive. Riffing fast and furious with Colbert will no doubt sometimes produce such slips.

By the way (and Brian does not get this wrong, but does not get the chance to say it, and I’m sure he knows it) people often get left with the impression from press releases about the LHC (see related posts below for lots of LHC background) and other Click to continue reading this post →
