Notes From the Day

By | | ,
23 Comments

The other day (some weeks ago now) I started a sort of “day in the life” post, to give you more of an idea of what a typical day was like at work (and maybe also a bit at play). Somehow I never finished it, and then I looked at it a while later and could not remember the rest of the day, and so just deleted it.

I’ve decided to do something different. There really is no typical day. So I will try to do a series of days instead. Of course, I’m not going to have tine to sit and do a long, detailed entry about these days, and so instead I’ll just do a sort of sketchy notebook, with some time stamps. From time to time during the day I’ll stop in and add to it, and then post the whole thing at the end of the day before going to sleep. I won’t include all details (I’ll spare you bathroom breaks, personal grooming, and things of that nature, you’ll be pleased to know), but will try to give you some impressions of how the day goes. If people are interested (and people did ask for such a “day in the life post” before), I might try to do them more frequently. But for now, I’ll try and do one for each day of this week. Average over them to get the typical day.

So here goes.

Well, this work week really started on Sunday night.

  • 11:15 – 11:48 pm (Sun): Thinking about structure of E&M course. When to set the next midterm (we agreed that the previously announced date was too soon). Also thought about what homeworks to set for the last part of electromagnetic waves in dispersive media, and though wave guides. Sent email to whole class about this.
  • 12:30am (Monday) After reading a random entry or two at the ever-brilliant Girls Are Pretty blog (e.g. here), I fall asleep listening to podcast of the BBC’s wonderful Broadcasting House (radio 4). I still miss the excellent Eddie Mair, but this new guy seems pretty good.
  • 7:15am (Monday) (Later rising today since it is Monday and I don’t have any early appointments and I try to get a good night’s sleep when I can.) Over cup of tea, read email. Delete about 30 spam messages that have arrived overnight. I note the kind letter from Dean X at institution Y acknowledging receipt of the long detailed letter in support of a promotion for candidate Z, and thanking me. Good that he/she did that. Took a good chunk of Friday and Sunday afternoon to write that epic.
  • 7:45am Not in a rush to go in yet, I have a longer breakfast – cooked some […]

That Feeling

By | | , , , ,
57 Comments

It is on the list of my top five all-time favourite feelings. But I know of no word for it in English that properly captures it. This is strange, since so much of our society relies on things that probably came about in accompaniment with this feeling. I’m sure you know what I’m talking about. Sometimes it come on so strongly that it feels like a switch has been flicked inside my head, with an almost audible “click”, often accompanied by a smile, an oral exclamation, or even a moan. Why can I not think of a word for it? Perhaps my vocabulary is failing me, but if there is not such a word, then we should set about forging a new one, since it is so important.

Those Fun Paper Titles

By | | , ,

Scanning the listings on the arxiv just now, I found what has to be the best paper title I’ve seen for a while:

“Would Bohr be born if Bohm were born before Born?”

It is a paper by H. Nikolic, in the history of physics classification, and I have not read it, but I love the title. It’s brilliant!

This reminds me of the process that happens to me sometimes when I’m working on a research project. I suddenly think of a really great title, and then get excited about finishing the project so that I can write the paper with that title! (You’ll have noticed that I do that with some of my blog posts too.) It’s often just a nice turn of phrase, like […] Click to continue reading this post →

Not Improbable

elaine chewOn Wednesday night, accompanied by Tameem, a student of mine, I wandered across campus to attend the “Mathematics in Music” event. I blogged about it earlier. I don’t really want to talk about the event itself in this post. It was a nice enough recital of three pieces. I don’t know why, but the promised “mathematics” was disappointingly virtually non-existent. I’m not exaggerating, I’m afraid.

Keep in mind that it may simply just be my misunderstanding of the intent of the event, but there’s simply next to nothing to report in the way of what was said about mathematical aspects of music. There were plenty of opportunities, but (almost) none were taken. I got out my notebook and pen, all excited at what the presenters might say at various points… and the mathematics never showed up. There were a few extremely elementary remarks about tonal ratios in chords, about scales, keys, and time, and that was it, more or less. This was a bit of a shame, since I suspect that Elaine Chew could have talked at length and with some authority on the matter (given the projects she’s involved in see e.g. here), but mathematics was almost completely missing in the event – despite the title. I imagine there were what seemed like good reasons for this. I was not party to decisions made behind the scenes, so cannot comment further.

More interestingly on that front was what took place in the minutes leading up to the delayed start of the event. First, although it was a free event, they pointed us to the box office where an attendant printed us two tickets from the computer so that we can show them to someone at the door who wasn’t really looking anyway. Fine. We got into the recital hall, but rather than sitting at the obvious available seats, I suggested that we move to the other side of the room where one can get a better view of the piano keyboard. I’m less than happy when I can’t see what a musician is doing, you see, so I always try to sit with the pianist’s view of the piano. So we did that, and found two seats. While we chatted and looked around us at the growing assembly, I spotted a friend and colleague of mine, the composer Veronika Krausas. She was in the company of someone who she introduced as Brian Head, who is a composer, performer (guitar) and music theorist (a “triple threat”, Veronika joked), also in USC’s Thornton school of music. They were looking for seats and there was one on either side of the two we were sitting in, and so they joined us and we chatted some more.

When the event start was about ten or fifteen minutes late -they were trying to get the reassuringly large crown all seated, they announced- Veronika idly looked at her ticket, pointed out that they were numbered, and wondered if we should have been […] Click to continue reading this post →

Unexpectedly On YouTube

third law jet demoI don’t know why this possibility did not occur to me before. So let me give you a heads up if you do demos in your lectures. In Physics 100 (which I taught last semester) and in Astro 100 especially, we do a lot of demos to demonstrate various physics concepts. I did a post on the Newton’s third law jet propulsion demo some time ago (linked photo right). My colleague Ed Rhodes did this same demo in his Astro 100 class.

He received an email from one of the students in the class recently saying “Congratulations, you’ve been YouTubed…”.

Apparently, one of the students in the class used his or her mobile phone camera to […] Click to continue reading this post →

All Hands on Deck

all hands on deck Well, it’s the middle of the Bleak Midwinter, and the first day of classes of the new semester. Mine start tomorrow. It is time to get myself back into the classroom-teaching frame of mind -although to be honest I don’t think the break was long enough for me to have got sufficiently far removed from it: 85% of the research tasks that I wanted to do during the break remain undone.

Anyway, I must sit and contemplate what I am going to talk about in the graduate course entitled “Selected Topics in Particle Physics”. It’s my lunch break, so I thought I’d chat to you for a bit.

Rumour has it that everyone is expecting some sort of string theory course, reasonably complementary to the one that my colleague Nick Warner taught here two years ago. I’ve no interest in just teaching the standard string theory topics – a good and motivated graduate student can just look them up in a book if motivated enough (if they can’t they’re in the wrong business) – and so I’d like to throw in some material that is not packaged together in the standard way, and give them an education that emphasizes powerful ideas and techniques that are relevant to more than just standard string theory research, but theoretical physics in general.

You see, this is one of the wonderful things about the topic that you don’t hear about much when people say things (and write books for a general audience) about how much it is supposedly taking over smart young minds and leading them astray: It is a fantastic framework for training good physicists for whatever new and useful ideas and physics will come along in the future, whether it is string theory or some other topic. The point is that string theory has developed in so many different ways, and […] Click to continue reading this post →

Last of the First

The other day, in a nice cafe on the boardwalk at Venice beach, I was working with Veselin Filev, a student of mine, on a paper that he would later submit to the arXiv. The end of the year was approaching and I wandered off into some irrelevant anecdote or other (as I am wont to do), explaining to him a bit about little traditions concerning the arXiv, from the “old days”. I mentioned in passing that one last tradition will come to an end because the numbering system for papers will all change sometime this year (apparently the mathematicians are close to producing too many papers in each month – more than the 1000 the system can handle1.)

I explained that in days of yore, some people would try to get the very first paper of the year, so that they would have a rather special number, of the form hep-th/XX01001, where XX denotes the year. By far the coolest of these was […] Click to continue reading this post →

Tales From The Industry X – Wired Science

Well, there was something I could not tell you about before that I now can. There’s a new TV show called “Wired Science” about to launch. It is made by the PBS affiliate KCET, and will air on your local PBS station (on Wednesday, January 03, 2007, 8:00-9:00 pm ET). It looks like it is going to be informative and fun!

wired science banner

Here’s some of their blurb from the press release:

WIRED SCIENCE is a one-hour program that translates Wired magazine’s award-winning journalism into a fast-paced television show. WIRED SCIENCE brings Wired magazine’s cutting-edge vision, stylish design and irreverent attitude to the screen with breakout ideas, recent discoveries and the latest innovations. The pilot episode takes the viewer into the world of meteorite hunters, where space, commerce and art intersect; travels to Yellowstone National Park to harvest viruses that may hold the key to a technology revolution; and dives underwater to explore NEEMO, NASA’s extreme astronaut training program. Viewers will meet rocket-belt inventors, stem cell explorers and the developer of an electric car that goes from zero-to-60 in under four seconds. As a series, WIRED SCIENCE hopes to span the globe to uncover novel developments in biomedicine, space exploration, artificial intelligence, neuroscience, robotics and military technology.

You can go to this Wired blog post to see the rather nice title sequence of the show, and the teaser trailer. To the right, there’s a screen shot I made just now (click for larger).

I don’t think that they have the go ahead to make a full series yet. This is a pilot. I imagine that whether they get the full series go ahead depends upon whether it is well liked and supported by you, the viewer. I’d say support it. the people behind it really care about getting good science programming out to you.

So what’s the big deal? Why did I not tell you about it if I’ve known about it for so long? Well, nobody told me not to tell you, but it seemed the right thing to do. You see, I have a little secret. How do I put this? I’m going to get so beaten up in the playground for this. […] Click to continue reading this post →

Research Blogging

Time to talk briefly about other uses of blogging. Some time ago I spoke about the idea of using blogging as a sharper tool for exchanging and even developing research ideas. The conversation about the suggestion degenerated into vapour, at some point, and having floated the idea and learned from the conversation, I left it alone. In public at least.

In private, I continued. The fact is that I have other blogs on the go. I’d like to tell you about one of them, since it might be a useful tool for you too. The way I use it is simple. I run my “lab” with it. It’s my virtual lab-space. I have about five students working with me, and a million and one projects, and not enough hours in the day. The students all are working on several projects with me, with each other, and alone…. but all under the umbrella of being part of my little “subgroup” of the larger high energy theory group here at USC. I want us all to have conversations, point at new papers, throw out ideas, show partial computations to each other (and definitely to me) for comment, share drafts of papers with each other, etc.

So far so standard. Normally, this is all done with emails back and forth, one on one conversations, etc. Sometimes those conversations can be supplemented by one or other person from the group (me, or anyone else) dropping in and setting the whole thing straight with a comment. Sure, you can do this with email in the “reply-to-all” mode, but…. […] Click to continue reading this post →
