Southern California String Seminar May 2011 in progressThe next Southern California Strings Seminar is on Thursday 13th December! I’ve now made the website for this one and it is here. Come back to it from time to time to see the updates of talk titles as speakers let me know what they are. It is a one-day event filled with five talks and plenty of time for discussion. I’ve snagged a lovely room in the Doheny library again. (Photo left has a shot of the room we used last time it was at USC in May 2011. The most recent one was over at UCLA.)

You are welcome to come and do physics with us! Also, if you’re part of a group in […] Click to continue reading this post →

The Fifth Feeling – All Episodes!

Recall the mock science doc I pointed you to earlier, the Fifth Feeling? Well, all the episodes are now online in HD, on Funny Or Die. You can see the remaining episodes (3, 4, and 5 since I posted) now, or watch them all, since they look great in HD. (Or maybe because you’re simply a huge Ray Wise fan from the good ol’ Twin Peaks days..?) Here’s episode 1 again to get you started if you’ve not seen the setup, and from there you can jump to the others*:

Ok, ok. I can’t resist posting episode 4 as well, because that doorstep conversation cracks me up every time… […] Click to continue reading this post →

Talking

Comments Off on Talking

…Again. I’ll be on the road again this morning. Heading to California State University Long Beach. They invited me to give a colloquium a while back and I agreed, and when I returned from New York last week I realized I needed to urgently spend a chunk of time thinking about what I was going to talk about, and designing a set of slides for it. The last couple of days saw me devoting a lot of time to it. Eventually I decided to dig back into ancient times (the 1990s) surveying some of the interesting things we’ve learned about strong coupling phenomena (involving unexpected reorganization of degrees of freedom and the number of spacetime dimensions at times), and then discuss what it all might be good for in view of work going on in the last decade or so.

Come to think of it just this moment, this is a chance to do a tribute to David Olive, who passed away earlier this month. (He was one of my professors when I was at Imperial College in the ’80s.) Ideas of strong/weak coupling dualities and their utility were given a huge boost by his work in this area from decades ago, perhaps the most famous being Montonen-Olive duality… I must remember to mention that in the talk. (See here for an archive of 2004 talks in celebration of his work. I borrowed the image to the right from there. I do not know who took it.)

Here’s the title and abstract: […] Click to continue reading this post →

Components

Here’s the first slide of my TEDYouth talk from Saturday. It was time consuming but fun to draw all those hands and tiny items of various sorts. The whole talk was about what I call “hidden structures”, which in a sense is what my field (high energy physics, particle physics, cosmology, string theory, etc.,) is all about. To help motivate it all, I started by talking about opening up your smart phone and figuring out how it works by taking it apart and discovering the components inside, and using the rules of how to put them together to deduce the structure of other things (see that second stage of the slide being delivered on stage*).

Since I’m hugely into getting people to learn by really getting stuck into things […] Click to continue reading this post →

So Good They Named It Twice

Well, it is great to be back in New York. Multiple times this year – hurrah! I’ve just got back from the Times Center where all the speakers have been running through their talks to smooth out kinks of various kinds (technical glitches, run time, etc). The senior TED people are here sitting in the auditorium and one by one we come up and go through things to give us a chance to get familiar with the stage, and to hear any thoughts or comments. (See tiny picture on the left.) People have done really good jobs preparing, and so most comments are simply ones of congratulations, with some small suggestions here and there with regards points of confusion, or sound levels, or run time. We’ve got six minutes. You heard me right – I must explain all of particle physics and research in string theory in six minutes. I like my challenges… Well, I spent a lot of time designing the content of the talk […] Click to continue reading this post →

Magnify!

Somewhere in there, somehow, I am keeping my head above water…just. But then I decide on something equivalent to tying extra weight to my ankles. Last week, while deciding on what I would talk about in the short time I have, I decided to do the whole TEDYouth talk graphic novel style of course… Which means hundreds of drawings… Why do I do this to myself? (I can recycle some of this for The Project, I suppose…) So I sat in the sun on Saturday afternoon […] Click to continue reading this post →

TEDYouth Approaching!

Ack! As you know, it has been an incredibly busy semester for me, but I still try to find time to tell you a bit of what is going on. Not long ago I got an email from the TED people asking me if I’d like to talk at one of their events. This event is for young people, called TEDYouth. It’ll be on November 17th. Well, this is such a good cause – how can I not do this?

TEDYouth speakers photoYou can see the announcement of the “incredible lineup” of speakers on TED’s site here. (I linked the photomontage they used there.) I’m looking forward to being in the audience to hear some of these guys talk!

So of course, I now find myself a week behind where I should be in terms of preparation, and in the middle of a whole bunch of other deadines… […] Click to continue reading this post →

100 Registered!

So one of the things that has been taking up my time is the USC Science Film Competition. Well, last week, an important (slightly nail-biting) deadline passed, and that was the date by which interdisciplinary teams should have formed (finding each other due to the awareness campaign I’ve been running around doing since August – with the help of faculty who kindly spread the word in their classes, the blog I set up, an article by Pam Johnson in the Dornsife News, and ads in the Daily Trojan), come up with a film idea, and registered it.

So the day came, and (of course) within 20 minutes of the appointed cut-off hour […] Click to continue reading this post →

It has been quite the busy period the last few days, so much so that one is tempted (but not overwhelmingly) to neglect to take note of wonderful things like the discovery of a planet in the Alpha Centauri system, or the awesomeness of my group of students in my graduate electromagnetism class who all did quite well in the midterm I set them. But I took […] Click to continue reading this post →

Chasing Tail…

At around 11:15pm, after driving for a while toward the general area, we spotted it. The tail, poking high above the trees, gas station, and power lines, with people walking purposefully groups with only two flows of pedestrian traffic: to or from something that must be a viewing spot. I quickly (and in retrospect, miraculously) found a nearby parking spot (at a prohibited time for that spot, like for all the other cars, but I figured even the parking enforcers were looking at other things at this time) and we walked over to where we saw the tail to find places where we could see the whole craft. And there it was, the space shuttle Endeavour, the youngest of the fleet of re-useable spaceships, the one from which they did the historic and crucial spacewalk that repaired the Hubble telescope that allowed us to see so much about the universe in which we live… parked next to the Randy’s Donuts donut. After a back view of the engines, we found an even closer view, from the side, where most of the people were, and marveled for a while.

Nobel Prizes!

Comments Off on Nobel Prizes!

So this first half of the week finds me largely trapped in meetings from 9:00am into the evening, as part of a task force I’m on. so I cannot write anything substantive about any of the prizes, nr point you to interesting material written about them. What I can do is (a) remind you that they are being announced daily this week, and (b) remind you that a first place to look to find out more about what a prize means and the significance of the work is the Nobel Prize site itself, which often has good explanations. In the past, I’ve also found that NPR has a good interview or two about the prize of the day, with a reporter valiantly trying to make sense of it for the host of Morning edition, so I recommend seeking those out by searching their site… If you find good sources, let us know in the comments if you like!
