A Treasure Trove!

As I’ve mentioned before, I listen online to Radio 4, one of the BBC radio stations I love for its variety, breadth and depth of programming. Between it and NPR affiliate KPCC, my day is usually rather full of (spoken-word) radio of a wide variety. I’ve noticed that Radio 4 has been doing a programme called “A History of the World in 100 Objects”. The Director of the British Museum does a 15 minute programme on each of 100 objects and talks about aspects of its historical significance. (If you think you don’t like history (maybe bad experiences in school or something like that) this might be a great way back into the subject for you. Not liking a subject is usually, I find, an issue with how it was presented to you and not with the subject itself.) It’s a lovely way of quickly plugging into aspects of world culture in interesting ways, and rather reminds me of the short series that we here at USC in the College Commons called The Cultural Life of Objects, organized by my colleagues Anne Porter and Ann Marie Yasin. (See also the Collections event, and my post about it.)

The BBC series is about half way now, and it has been quite wonderful. I strongly recommend it to you. Here’s the marvellous thing: The entire series can be podcast […] Click to continue reading this post →

Comments Off on Laserfest Videos

laser_beamI think I mentioned a while back that as a celebration of the 50th anniversary of the Laser, there was a video competition on Physics Central to make a fun video about the Laser. They were put on YouTube (tag is laserfest, I think) and then there was voting at some point (I imagine), and winners were chosen. You can see them here. Congratulations to the winners!

Actually, I think the whole playlist of Laserfest video entries is here, and you can jump through them by clicking the link to the next one in the top right hand area.

Are you aware of Laserfest, by the way? Go and check out the website and join in the celebrations of the Laser!

I should mention that the competition has all meant good news for my work as well. I […] Click to continue reading this post →

Planck Matters

You can read a bit about the work of my colleague Elena Pierpaoli and her postdocs and students in this article in one of USC’s in-house publications. It focuses on the Planck observatory (image right from NASA/ESA), which we’ve discussed here before. (Recall the launch?) There’s a lot of exciting physics about the very young universe to be discovered as more data from the mission get gathered and analyzed.

Enjoy the article!

He Had Problems…

vaderYeah, there was something wrong with that Darth Vader guy, don’t you think?

An official diagnosis was reported in the journal Psychiatry Research. Seems the poor fellow was afflicted with a personality disorder. This is the claim, anyway. There’s a post about it here that’s worth looking at*. The most entertaining bit (for me) is probably the comment stream from the rabid fanboysandgirls (as you might imagine for something about Star Wars).

For me, the best insights into the fellow are to be found in his blog which I remember from a few years back. Still quite brilliant. (Be sure to scroll to the bottom and read the posts in reverse order to get them in the right order.)

Back to the diagnosis post. One of my favourite comments, after all the people […] Click to continue reading this post →

Understanding Artificial Life

Comments Off on Understanding Artificial Life

You’ll remember the recent announcement about the first synthetic life form, created by team Venter. But what does that mean, really? How truly synthetic is it really? What aspects of Nature needed to be input in order for it to be viable? Too much for it to be called truly synthetic? What dreams are out there to do better? What’s the science behind such a challenge? How did the mechanisms for life that we know know actually evolve, and what steps are adjustable or reproducible?

These questions and many more are addressed in a lovely special edition of BBC […] Click to continue reading this post →

Search Results

Googling people is often interesting. One thing I’ve noticed is that in the search results it seems people are showing up a lot more on various kinds of databases, business networking groups, social networking groups (of course) and so forth. Is this a growing phenomenon? Are people joining more of theses, or are various network entries automatically generated? (I ask this as someone who walked away from facebook, for example. Perhaps I’ll talk more about why some other time…)

In this vein, I forgot to mention that a little while ago I discovered that I have a Wikipedia entry. I am not sure how I feel about this, but it is (I suppose) flattering that someone took the time to add this to the things out there on the web about me. (I don’t think it was automatically generated.) I’d previously assumed that if an ordinary person had a Wikipedia entry it must mean that they wrote it themselves. After all, who would be interested enough to write one about someone else? Seems […] Click to continue reading this post →

A Short Cut to Mushrooms (Again)

Yeah, I know I’ve used this post title before, but I do love it. So… sorry.

One of the things that really sets my week up nicely is my Sunday visit to the Hollywood Farmer’s Market. Today was an exceptionally nice day for it, but weatherwise and just the overall atmosphere of the market. The people making their food purchases and simply socializing, the vendors, the many musicians (even the corny ones sounded really good today), and of course – the food itself.

One of the highlights for me today was a new (ish) vendor, specializing entirely in mushrooms.

The variety was fascinating, and I stood there with a friend sniffing and sampling for a while (encouraged by the vendors, I hasten to add) before purchasing a lovely persimmon enoki (the ones in the middle of the first photo):

Organized Skepticism

By | | , ,

(The title is an important way of thinking about what science is all about, at least in part. It is one of the things mentioned and discussed in the lectures discussed below.)

martin_reesThe annual Reith Lectures at the BBC over in the UK are under way. This year, they are given by a giant of astrophysics, Sir Martin Rees. I strongly – very strongly – recommend listening to these lectures. There are four of them. Of the senior superstars of science who I’ve come to know a little, Martin Rees comes across as one of the most gentle and quietly thoughtful I can think of while at the same time being sharp and insightful on all sorts of aspects of science (not just the confines of his field). I mention these characteristics since they are of great value to me – I tend to be repulsed by the practitioners of the more arrogant style that is also common in prominent (and not so prominent) scientists, no matter how good their science might be. He’s the President of the Royal Society, the Astronomer Royal, and the Master of Trinity College (Cambridge), among other distinctions, and so naturally is called upon to express views on a range of topics about science, including how it intersects with society.

Indeed, the intersection between science and policy issues and society is the subject of the first of his lectures. The whole series is called “Scientific Horizons”. The first […] Click to continue reading this post →

Formal Physicists

Since (as high energy theorists working on foundational issues for most (but not all) of our effort) we can be called by some “formal” physicists, or physicists who are concerned with only “academic” issues, I thought our outfits in this picture from last month were quite appropriate*. (Now don’t you just want to hire this dream team to swoop in and solve all your problems? Click for larger view. )

Backstory: Some of the students in the group did a bit of pomp and ceremony to receive their Ph.Ds, and some of the faculty joined in.

Hilarity ensued.

Summer Reading: Of Bookstores and Lemon Cake

By | | , , , , ,

There’s something enduringly lovely about local independent bookstores. I love stopping by to visit them, try to give my local ones the first shot at supplying me with a book I’m looking for, but most of all I value them as community centres at the heart of the villages (real and virtual) that exist in our neighbourhoods, even in a vast city like Los Angeles. People gather and linger at them, bonding over the written word for the most part, but sometimes just for the sake of gathering and lingering. In that role they are a lot like public libraries, another favourite of mine. Much of what I said can apply to the large chain bookstores too, but somehow I find them less likely to have that community feel that independent stores have. I’m not sure why (location? focus? less of a personal touch in the organization of the material?), but this is the way it seems to me. (I’m speaking about the USA; the feel of bookstores is different to me in different countries.)

aimee_bender_reading_3Last night, after a quiet evening meal after a long day of working on the Project, I went for a nice long walk, heading to Skylight books in Los Feliz. (That’s the neighbourhood at the base of the hills of Griffith Park, in case you don’t know.) My friend and colleague Aimee Bender was launching her new (long awaited) novel “The Particular Sadness of Lemon Cake”, and I thought I’d go along to support the launch, hear about the book, and absorb a bit of the buzz. And buzz there was, since in addition to […] Click to continue reading this post →

CDF Says No

Recall the excitement last week about the D0 result? I wrote a post called “An Exciting Asymmetry?”. Well, there’s a rule that says if you write a title as a yes/no question, the answer is often (usually?) “No”.

Sure enough. over at Resonances, Jester reports that the CDF experiment, also at the Tevatron, has looked for a confirmation of the CP violating result that D0 claimed to see, and did not find anything abnormal where it should have. Find further details (on the technical side for the experts) and links at that post, which, as is usual with material from that blog, is well-written and interesting.

This is one reason why we (the particle physics community) build multiple detector/experiments on the same accelerator machine, and this is a prime example […] Click to continue reading this post →

Alternative Synopses

Will is annoyed by the Karate Kid (2010 version, not the 1984 version), not the least because with Jackie Chan involved, you’d be expecting… Kung Fu right? Weren’t we supposed to have stopped confusing the forms back in the 70s or so? People are up in arms about this all over the web it seems. I’ll lay off the whole thing since I’m not an expert in the etymology of the terms anyway, but more to the point I’m just tired of having my childhood memories cynically smacked around by pointless remakes, if the truth be told.

Anyway, to help himself vent, Will wrote some amusing synopses for other remakes Hollywood might do where the details are… modified. Here are a couple I liked: […] Click to continue reading this post →

The Runaway Black Hole

In recent years there was all the nonsense about how scientists were going to accidentally make a black hole with the Large Hadron Collider that would runaway out of control…. we would not be able to stop it. We scientists would have tampered with the murky depths of Nature and awoken a monster we could not control. Naughty scientists that we are. The LHC has been colliding away at unprecedented energies, and last time I checked (you can too – click here) we’re ok.

gusher_oilI just realized something. Now we do have a runaway black hole! But it was created by naughty engineers, tampering with the murky depths of Nature and awakening a monster they cannot control. That gushing well 5000 feet below in the gulf of Mexico is a black hole […] Click to continue reading this post →

Nostalgia

aollogoAOL is 25 years old today! Twenty Five! To help you understand that, those of you who where alive then click here for the list of number one songs in the charts at the time… Yes, Wham!, Tears for Fears, Huey Lewis and the News, Phil Collins, Jan Hammer, etc… Do you remember America Online? Dialing up to connect? (Perhaps some of you still dial up, to read this blog?) Ah yes, memories. I was never an AOL subscriber. I was, after all, not in America until the 90s, and only started connecting from home in that decade. By then several companies offered dialup service. Then I was of course, just like everyone else, familiar with the reassuring dialup noises to the point where by ear you could tell if the connection was going to work or not (huh, I just realized that sound is sort of from the same swatch of sounds as the TARDIS noise), and recall the sitting and waiting for files of just a few hundred kilobytes to download, and so on and so forth. (Amazingly, and wonderfully, we are now at the point where people are streaming movies and tv shows directly to their homes on their web connections.) The speed difference became a way of measuring the difference between work and home, in a way. At work, you had tons of storage space and perpetual connectivity, and once got home that went away. So waiting for data to squeeze through the telephone line using dialup was extra frustrating.

Truth be told, there’s a piece of me that does not mind that difference, at times. Being connected all the time at home – fast and conveniently – can bring down the […] Click to continue reading this post →
