Branson Adds Pickle

AP photo of Branson and GoreCalling all scientists and engineers. You’ll get a $25 million prize from Virgin’s Richard Branson if you find a way to extract greenhouse gases from the atmosphere. Get to work!

Continuing his admirable campaign to do more useful things with his money instead of engaging in the (let’s face it) mostly silly stunts that used to characterize news stories about him, Richard Branson announced his new prize today in London (in the company of Al Gore) People are indeed working on this sort of thing, in case you’re wondering (see a post I did earlier, for example).

No, this is not a replacement for increasing our efforts to change our habits […] Click to continue reading this post

Triton Talk

The title of Monday’s colloquium was “The Cryogenic World of Triton”, and the speaker was Gary Peterson of the Department of Geological Sciences, San Diego State University. Here he is in action:

The talk was very qualitative. Perhaps at times too qualitative for a lot of the Physicist audience, I’ve gathered from comments, but everyone agreed that it was still very interesting. Some of the qualitative aspects were necessary, since there’s not much data available for the sorts of things he wanted to talk about. So he was extrapolating […] Click to continue reading this post

Space Opera

Well, I tried to avoid blogging about this, starting yesterday since I was really annoyed that its initial appearance as a story was in the Science section of a number of organizations, and it has nothing whatsoever to do with science. But now that it has arrived in the more general news sections of some publications (see a nice Independent UK article here, for example), I am happier to talk about it, and also to briefly remark upon any tentative connection with science that might be there.

The case is the one concerning the arrest of astronaut Lisa Marie Nowak on what has now been alleged to be attempted first-degree murder. (It stated out as mere vehicle burglary, battery, and destruction of evidence, but was later upgraded.) Basically, in case you’ve not heard, Ms Nowak drove 950 miles from Texas to Florida to stalk and […] Click to continue reading this post

How Many Legislators Does it Take to Change a Lightbulb?

This is a joke (the title) that works rather well, while being a serious issue as well. It’s all about trying to reduce our energy waste here in California, and contribute to the commitment to reduce greenhouse gas emissions. The idea is to change from the garden variety incandescent bulbs … Click to continue reading this post

Philosophia Naturalis #6

the brainI just learned that the blog carnival Philosophia Naturalis #6 is underway. It is hosted at Science and Reason. Several city blocks have been shut down to make room for the revelry you get at carnivals.

The monthly collection of recent posts on physics and related topics from around the blog world is very good, and I bet that there are several that will catch your eye. Go and look!

Don’t forget to ask the Brain (click right) a question!

Sabine Hossenfelder: My Inspiration

Sabine HossenfelderToday, a guest post. I’m excited, because it’s from one of my favourite bloggers, Sabine Hossenfelder, or “Bee” as you may know her from her comments here, and of course her blog Backreaction.

Bee giving a guest post here on Asymptotia originated in a suggestion I made in the comments of an earlier post of mine. Bee had asked me to do a post on her blog as part of her excellent series of guest posts about what made her guest choose to go into physics. Pressed for time, and not sure whether I’d really have anything new or interesting to say about myself, I stalled for time (I thought) by saying I’d do it in exchange for her doing a post here on a similar subject. She rapidly came up with the post. And of course it’s a great one. I’m so on the spot now.

Anyway, here’s Bee! -cvj

I just sat down with the best intention to write a lengthy blah on Clifford’s question what inspires me. Now that I sit here, hands above the keyboard, I am facing a problem. It’s not that the question is too difficult, it’s too easy to answer. I get inspiration everywhere. Reading books, seeing movies, taking a walk – ah yes, also from scrolling through blogs. Most of all by talking to my friends and colleagues. The problem is now that I’m too inspired not to shamelessly use the opportunity of writing a guest post for Clifford 😉 So let me redirect the question to your opportunity to use your inspiration.

Hubble Trouble

hubble graphicAs you can tell by putting “hubble” into the blog’s search engine on the right, the Hubble Space Telescope has been a strikingly successful eye on what’s going on (and what went on) in the universe, and very powerful tool in lots of research. A lot of that research is done with the instrument called the Advanced Camera for Surveys (ACS), which have been the instrument in most heavy demand by researchers since it went online in 2002 (Hubble was launched much earlier, in 1990 of course). The instrument stopped working a few days ago (see e.g. stories here and here, [update: and especially here]), and is not expected to become operational again without direct intervention. Given that the Hubble orbits some 360 miles above the earth, this is not an easy thing to do.

There are other instruments on board too, but the loss of use of this one is a heavy […] Click to continue reading this post

Talk about the Talk

charles stevensChuck Stevens’ visit went very well indeed. The talk was excellent, and well attended by faculty and students from both Physics and Astronomy Department, and the Neurosciences Research Institute. I’ll tell you a bit more about what he said in a subsequent post, along with pointing to video and slides from the talk, I hope. (Click on left for larger view.)

By the way, when I got to the Steve Reich concert venue, there was a huge line of people waiting to get in. They eventually turned a lot of us (myself included) away due to lack of space.

So I got on my bike and cycled rapidly up Figueroa Street to downtown and found the restaurant where some of my colleagues had taken the guest for dinner. Excellent conversation instead of excellent music. A good trade.

Here’s something I passed on the way to the restaurant. Took a picture while waiting […] 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
