Physics Nobel for String Theory Instead?

So I don’t usually talk too much about raw politics here, but when the news broke early this morning about the Peace Prize for Barack Obama, I was sure it was a joke. (Or perhaps I was mishearing given that it was almost 2:00am and I was just coming home from a long night downtown which finished with several hours at the Edison bar.) When I woke up five hours later and heard that he’d accepted, I was a bit sad. I think it is simply a mistake, and a distraction. You give the prize to someone for having done stuff. Plain and simple. He has not really left the starting gate yet. (And frankly, on almost all counts – not just peace – he seems to be still at the starting gate trying to find his way out of that little box.) But it is nine months into his presidency, so good or great things can happen yet. But they have not yet. So this prize looks like a lazy political slap in the slap in the face of the Bush administration, a cheap political statement that backfires and cheapens the prize. Obama would have had a huge amount of respect from me if he’d at least tried to respectfully decline.

So stepping away from direct politics I was trying to think what might be a fun and instructive thing to think about this. How about alternative prizes for this week’s categories? Prizes to work (or authors of the work) that while extremely promising, Click to continue reading this post →

Margaret Atwood

I’m not normally a giddy fan of anyone, but I’m super-excited! Margaret Atwood is talking at UCLA on Friday about her new book (The Year of the Flood, sequel – kind of – to the excellent Oryx and Crake) and I managed to snag a ticket online to see her. (There’ll be readings from the book and also some illustrative performances/enactments by actors and musicians.) I was scalped 25% on the ticket price in “service charges” by ticketmaster, which left a bad taste in my mouth, but then I remembered her voice and wit and humour and it somehow made it all ok.

If you’ve not read any of her work, perhaps begin with The Handmaid’s Tale and go from there. I love her brilliant writing style, wit, cleverness, humour and searing Click to continue reading this post →

jane_goodall_bovardJust went to a marvellous talk by Jane Goodall here on the USC campus, in Bovard auditorium. She’s signing her new book as we speak! Among the many things she said, she emphasized one of my favourite themes with regards the environment (and so many other things, like community, education, etc): Act locally.

Have a look at her roots and shoots organization for example. It is very youth driven Click to continue reading this post →

The Nobel Prize Week is here!

As you already know, I am sure, it is Nobel Prize week. (See posts below for earlier such discussions.) Physiology/medicine has already been announced (see here: Yes, I definitely approve any effort to encourage research work on how aging and related mechanisms work)…. what was I saying again?… Oh, right …and Physics, Chemistry, literature, Peace and Economics will trot along into the spotlight day by day, into next week. All very exciting.

[Update on the Physics prize at bottom of post!]

Now I have to say I don’t have any good ideas or strong feelings for what the Physics prize might be this year. Do you? I’ve a vague feeling that it might be some sort of important experimental effect (you know, like GMR a few years back – perhaps whatever it is that makes my ipod know which way is up all the time) instead of something flashier (but no less important) like inflation (the cosmic kind), which I am sure will have its day one day soon.

Ideas?

By the way, my “Nobel Prize: Who/What/Why” colloquium idea of a few years back has now been converted into a pair of lunches for the College Commons series. Click to continue reading this post →

All Went Well…

When all is said and done (and since it is midnight and there’s nobody else here, I’ll take it that it has been and is) it was a good day at the West Hollywood Book Fair. I made it there in time to wander a bit and take in a number of the things on offer, just flitting from booth to booth and stopping to listen at various panels on various of the stages. chair_at_pdcI arrived early enough to check to see where my panel would be, double check that there were no schedule changes, and then set about to look around. Just before the panel I found a place doing a nice tasty hot sausage on a bun for lunch (plenty of fried onions and a sliver of mustard to top it all) and nibbled on that while listening to some poetry readings. (Or at least I think that is what they were.) (The picture shows the late afternoon sky with the giant chair sculpture at the Pacific Design Center across the street from the park the fair was in.)

Then I went to find my fellow panel members and we, uh, panelled away for an hour. Crucially, I found out what my panel was really about, which is good. The title “Eyeballing the Universe: Big and Small” was intended to invoke not just the act of Click to continue reading this post →

There Goes the Weekend

viscosity_scatterI’ve no idea why I do this to myself. I was just about managing things schedule-wise and aiming to make sure I have some fun on the weekend when the following thing happened. I went to Monday’s departmental colloquium and before it, ran into Moh, our organizer this year. I’d been trying to see if there was still room to schedule a speaker I’d thought of inviting, and he mentioned that the dates we’d earlier discussed had all been filled. Then he mentioned that he was desperately trying to find a speaker for next Monday, and was thinking that he’d have to simply cancel it that week.

This was at 4:05pm. Now watch how rapidly I move to ruin a perfectly good schedule Click to continue reading this post →

Out There

cvj_scribbling_boardWell, I’m always a bit embarrassed to point to articles that are about me, especially ones that are decidedly generous – I’m British, remember – but it is specifically about some of the work I do when I’m not doing research, classroom teaching, sitting on committees, and so on and so forth. Things like blogging, and things that might be called “media outreach”. Lots of people ask why I do so much of this sort of thing, and so it is worth pointing to this recent piece by way of a partial answer. (The other part of the answer is to do with the response to and (possible) lasting effects of this sort of work. It is surprising in both quantity and variety, and quite humbling at times, and I’ll tell you about it in another post.) The article, written by Laurie Hartzell (with photo above left by Mara Zimet) for USC Click to continue reading this post →

Clusters

I’m sitting on the sofa watching what has so far been a really excellent episode of The Universe on the History Channel. It is entitled “Cosmic Clusters” and it has been a lovely journey (15 minutes show time gone by so far) on an imaginary spaceship ride through the galaxy looking at formations of star clusters, and discussing the process of star formation in those clusters, their birth and the conditions involved, how those conditions change as things progress, the different kinds of stars that can result, the curious case of globular clusters (M13 is pictured below, by Yuugi Kitahara) and so forth. I think it is going to go on to discuss clusters of galaxies, and clusters of those…

bookfair_homeMark your calendar for Sunday! The West Hollywood Book Fair is on from 10 am to 6:00 pm that day, and there’s so much to see and do with readings, panels, discussions, authors, special celebrity guests, food, exhibitions, writing workshops, discount book offers, signings, swag (no doubt), and so forth. I’ve not been before, but as you know from reading here I’m a big fan of cities going gaga over books for a while, being a regular visitor to the LA Times Book Festival when it comes in the Spring. The calendar of events and much more about the event can be found at the website here.

Here’s another thing. Despite the fact there was no mention of a spankingly splendid Click to continue reading this post →

optometerySo, do you like it? My new glasses. Think it’s a good look for me? Sort of gadgeteer-scientist extreme. With this I get all the different optical instrumentation combinations I need in one nifty device. Long distance viewing for seeing whether my bus is coming from a long way away, lenses for extreme closeup work in the workshop, night vision, the works…Neat, no?

Ok, I’m being silly. I went to the optometrist today after a bit of a long period between tests, and I always find it an interesting experience. I’m not sure why, but it Click to continue reading this post →

Ahmad Jamal

ahmad_jamal_concert_3Yesterday at some point I decided I was in the mood to see some good live Jazz, and checked out the program at the Catalina and considered John Patitucci and his trio. There was still no Jazz Bakery schedule to check as there is as yet no news as to whether they will be really coming back at some venue somewhere… I thought I’d scan a few more places and noticed that a venue I’d not been to before had… Ahmad Jamal! Gosh, how did I never notice Jazz at the Nate Holden Performing Arts Center before? It is right in mid-city on Washington between Crenshaw and La Brea, near where in days past, there were several Jazz clubs such as The Parisian Room, The It Club and The Hillcrest Club. (All now gone, sadly, leaving a relative vacuum in terms of support for regular live Jazz in the heart of the city.) While the Nate Holden does not look to be set to become a regular Jazz venue featuring great music every night, there were encouraging things said in the announcements before Ahmad Jamal came on to play. Things that voiced an awareness that people miss those places, and the Click to continue reading this post →

Speed Demons

karpov-vs-kasparovHave you heard about the rematch between Kasparov and Karpov, in commemoration of the classic matches of the 1980s? (I was always a Kasparov fan, myself). What is different about this time is that they are playing speed chess. (Collective sharp intake of breath… distant tinkling sound of dropped gins-and-tonic all over the web…) There’s a nice story by Giles Tremlett in the Guardian with some background on the earlier matches, their rivalry, and some discussion of the 80s era for those of you who suspect that period was only in black and white. There are some nice pictures (old and new) here. I cheekily borrowed the one above right (credited Kai Foersterling/EPA) for this post.

Look, the K vs K speed chess thing was bound to happen, given our increasingly limited collective attention span. Everybody is apparently too busy to take time to focus on anything for much of a length of time, so adjustments are happening to…

moonWell, I’ve been somewhat neglectful of lots of space and astronomy type noticing (here on the blog) in the last couple of months or more, but it is not unusual for me to re-balance my foci a bit as my interests and available time permits. However, I’ve been meaning to point to the quite astonishing results that are being discussed in recent days… The confirmation of what appears to be a remarkable amount of water on the moon. It is an indirect set of measurements, using spectroscopy, (using results from three separate spacecraft) and is quite an interesting story. Happily, Phil over at Bad Astronomy has just put up a rather splendid summary of the story and I’m simply going to recommend that you pop over there and have a read. (There’s also a Space.com story by Andrea Thompson that is nice too.) Very interesting in the whole thing is the discussion of how the water got there, and why it is rather more mobile than you might expect (clue: the sun might be involved).

Doomsday Fun and Games

Comments Off on Doomsday Fun and Games

the_universeI’ve been wondering why over the last day or two I’ve been getting email about various apocalyptic scenarios. I’ve now figured out why, I think. On Tuesday, several scientists, myself included, played with the idea of how to destroy the earth! Well, it was on the History Channel in an episode of the show the Universe, (it was recorded back in June and July) entitled “Ten Ways to Destroy the Earth”. Of course, these are not scenarios we envision happening any time soon, but rather an excuse to talk about various kinds of science (from spontaneous symmetry breaking and the early universe, through planetary science, solar physics, and of course black holes and more). We list various favourite ways that were chosen to be discussed, and each physicist (although they called me an astrophysicist) picks a favourite. Fun stuff.

I chose putting a huge amount of antimatter at the core of the earth and letting it Click to continue reading this post →

Len Adleman: Quantum Mechanics and Mathematical Logic

Today I’m pleased to announce that we have a guest post from a very distinguished colleague of mine, Len Adleman. Len is best known as the “A” in RSA and the inventor of DNA-computing. He is a Turing Award laureate. However, he considers himself “a rank amateur” (his words!) as a physicist. len_adleman He’s one of my colleagues on whom I can always rely for a fun and interesting conversation, even if it is just for a fleeting moment during a chance encounter in an elevator. The other day he told me he’d been thinking a lot about quantum mechanics, and it seemed like it would be fun to share his thoughts with others here on the blog. So join in using the comment form if you’ve some thoughts of your own in response.

Here’s Len.

For a long time, physicists have struggled with perplexing “meta-questions” (my phrase): Does God play dice with the universe? Does a theory of everything exist? Do parallel universes exist? As the physics community is acutely aware, these are extremely difficult questions and one may despair of ever finding meaningful answers. The mathematical community has had its own meta-questions that are no less daunting: What is “truth”? Do infinitesimals exist? Is there a single set of axioms from which all of mathematics can be derived? In what many consider to be on the short list of great intellectual achievements, Frege, Russell, Tarski, Turing, Godel, and other logicians were able to clear away the fog and sort these questions out. The framework they created, mathematical logic, has put a foundation under mathematics, provided great insights and profound results. After many years of consideration, I have come to believe that mathematical logic, suitably extended and modified (perhaps to include complexity theoretic ideas), has the potential to provide the same benefits to physics. In the following remarks, I will explore this possibility.

But, be warned: I am not a physicist and these ideas are embryonic. At best they indicate a possible direction; a fully functional theoretical framework, if possible at all, would be the work of lifetimes.
