Gloomy Sunday

By | | , ,

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 →

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 →

Looking Forward…

new_books…to lots of happy reading soon! My new crop of shopping (click for larger view) includes three Octavia Butler novels, two Murakami novels (I think I’ve talked about both authors here before) and a science book by Garfinkle and Garfinkle (I’ve spoken about this excellent book here before) that is a gift for a friend. I actually tend to cluster authors from time to time, meaning that I read something of theirs and then consume several more of their pieces of work immediately after. I did that with Murakami a while back and it is time to come back to him and read some more. Then it’ll be a Butler cluster.

Now… just need to read them. I can’t wait…. but I must finish the astonishingly good […] Click to continue reading this post →

Blue Skies…

I always like an excuse to look for blue skies, and to have others look too, even in the worst of times. I had a great reason to do it today.

Early this morning before sunrise I settled down to write my ten o’clock lecture for my Electricity and Magnetism class. On Tuesday I had ended with a computation that is the essence of the reason the sky is blue, which is a nice enough thing to talk about, but today I wanted to go more in depth on the whole thing, and show that you can in a few steps show that the blueness has a particular pattern to it. I wrote out the final equations in a few steps and looked at them for a moment or two and realized that with the sun rising at that very moment, it was the perfect situation to have! So I went outside to enjoy the beautiful Autumn day and the beauty there is in seeing an equation writ large in the sky – and it really was all there.

It is particularly at times like this that one remembers why it is that it is hard not to just love Physics! (I hope you’ll forgive my unashamed love of what I do.)

Here is the sky I saw, looking toward sunrise, and directly in the opposite direction:

Oh, you’re wondering what I am talking about..? Why is the sky blue? What pattern in the sky? Thanks for asking! There are two things I’m looking at. First, light from the […] Click to continue reading this post →

Sketches while Zonked

Once again I find myself in the position of having far more to tell you about than I have either time or energy for – and so much of it is really good!!

I was supposed to tell you about the first of the Nobel Prize lunches that I helped put on last Thursday… Never got to blogging it, and now the second one finished an hour ago. The whole business was quite a success, I am happy to say. I’ll maybe come back to say some more… But I’m zonked right now with tiredness. Super-long day that started early, and I sort of started off tired to begin with. I’m sitting on the bus letting it drag me toward home… From the bus stop I will wheel the bike home because it has an inexplicable medium-slow puncture, and I’m too tired to ride anyway.

What other things have I not told you about?

Well, on Friday I went along to another wonderful event. The Los Angeles Institute for the Humanities had Josh Kuhn give a talk in their fortnightly luncheon at the USC campus. It was about Mexican music in Los Angeles. It was a wonderful and […] Click to continue reading this post →

A. S. Byatt

Following hot on the heels of Margaret Atwood coming to town last week (over at UCLA), we have A. S. Byatt over at USC today! Very exciting. It is actually partly one of our College Commons events as well, and last week as a College Commons event (with a Darwin tinge) we had a viewing of the film of her book Angels and Insects, which I thought was really excellent!

Her lecture is entitled: “The Novel as Natural History”, (and will resonate with some of the themes I talked about in my report on the CC event about Collections) and I expect it is going to be quite wonderful. Details here, and the blurb goes:

Saturday Shopping in Bed

buying_in_bedYes. Really. I got up early as usual and decided after to go back to bed with a cup of tea. Then I made a cup of coffee and retired again. I’ve decided to be a bit decadent this morning and try to take it slow and spend some quality time with my laptop doing some long overdue things such as replying to a number of emails, and….. shopping!

No, I’m not buying lots of shiny toys. It’s plane tickets and train tickets. For work travel. Three separate trips. Lots of planning, poking about on the calendar, hunting for good slots for flights, anticipating delays and building in appropriate lag times, coordinating various errands and meetings here and there… Basically, looking into the future and squeezing parts of it into some sort of shape. A scaffolding, as it were, for draping the details onto later.

One annoyance and one delight:

Audience View

Comments Off on Audience View

colloquium_audienceA shot of the gathering audience for my colloquium two weeks ago. (Click for larger view. I mentioned the circumstance behind it here.) It was a lot of fun, I must say. I spent a good deal of time preparing the slides in the day and a half leading up to it, and it was worth it. The audience seemed very attentive (or perhaps they are collectively very good at faking) and I got some great questions along the way, and at the end. My hope was to do a short and sweet colloquium […] Click to continue reading this post →

Emergence

emergence_snapYou might remember a post I did back in January from Cambridge (the one in England), mentioning what I was up to on that quick trip.

It was a board meeting of the Institute for Complex Adaptive Matter (ICAM), and I said, among other things:

ICAM has a great deal of interest in outreach -communicating science to the general public- and education, and this is one of the reasons I’ve been added to the board, since I’ve some experience and ideas to share in an advisory role. I’ll be giving a talk about some of these things using some projects of mine as examples (ASTI, blogging, etc). They’ve already been doing wonderful things in education and outreach, and have made it a priority to make it a major part of future activity. […]

I mentioned that one of the projects under development was their site called Emergent Universe, which promised to be rather fantastic to explore. It was under development at the time, and we (the board) spent some time at the meeting commenting on and making suggestions for its improvement. Well, it is finished, and boy it looks great! Suzi Tucker and her team should be immensely proud of their accomplishment.

There’s so much material there, beautifully presented (a still taken from it is […] 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.

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 →

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 →

Len Adleman: Quantum Mechanics and Mathematical Logic

By | | , , , ,
32 Comments

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.

For most of my academic life, my primary topic of research (and affection) has been […] Click to continue reading this post →
