Work on the Play Day

science play cartoon cvj“The Play’s The Thing!” you yelled, as you got out of bed this morning. Well, at least for today. Today, you’ll mostly be sitting in one place with manuscript, paper and pencil. Scribbling. Crossing out. Scribbling some more. Making notes, etc.

Yes, today is work-on-the-play day and it will be very interesting, since you’ve not looked at the thing for a long time due to other commitments. Certainly not since it was read by real actors with real people in the audience at the Pasadena Playhouse during the Summer, although you could not attend, due to being out of town. You wonder if it was as fun as the other public reading, and whether readings will ever be as magical to you as that first private one.

Looking at the manuscript with fresh eyes, you’ll form the opinion that it has become a Click to continue reading this post →

Time for the Inventor Story

three way ping pong by katrin stantonYes, right on schedule! The UFO story was yesterday, and today the Inventor story.

It starts out with his revolutionary three-way ping-pong table (of course! – and it’s called TriPong1), but before I even clicked on it I knew there’d be a “oh, and by the way, he has an alternative theory of the universe”, at the end.

I was not disappointed. My favourite bit of Katrin Stanton’s AP story (the photo at left is from the article):

What is it with Saucers?

flying saucer sketchNo, really, I want to know what the reason is. Most times you hear these Unidentified Flying Object (UFO) stories (or Unidentified Aerial Phenomenon stories, as we’re supposed to say these days, according to the Chicago Tribune’s Jon Hilkevtich), it’s a flying saucer that’s been apparently seen Why this shape? Where did it come from? Did it predate ficition writings, or come as a result of them? It is an idea that they ought to be symmetrical somehow? Then why not a flying sphere (which would be awfully cool)? Or a flying cylinder? Given that aerodynamics are not really at issue (it seems) with the astonishing technology these things are usually reported to have, why on earth not a flying teacup, for that matter?

Does anyone know or have a good theory about the origins of the flying saucer in our collective imagination? Do people report other shapes more commonly in other cultures?

Yes, there’s always the explanation that you hear about flying saucers more than other shapes because that’s the preferred choice of vehicle of the Visitors, but I’d like to Click to continue reading this post →

Hooking Up Manifolds

I love crochet. I spent a huge number of hours doing it when I was young, and only in later years did I realize that the same things that attracted it to me then are the same things that drive and motivate a lot of my research interests. (I many have mentioned this before, but it’s worth saying again).

It’s the love of patterns, plain and simple. If your child -of whetever gender- gets 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 →

A Different Perspective

The Bad Astronomy Blog gives a top ten list of astronomy images for 2006. There are some really wonderful choices there, and Phil Plait gives a good deal of discussion of each one. The winner is this fantastic back-lit (by the sun, not some giant NASA flashgun) image of Saturn taken -of course- by the Cassini mission:

This is a diagram of the layout of the equipment on the Corot (COnvection, ROtation and planetary Transits) space telescope, launched recently from a site in Kazakhstan.

corot satellite

It’s a European Space Agency (ESA) mission, primarily run by the Centre National d’Etudes Spatiales (CNES – the French Space Agency, if you will) and it’s going to be looking closely at about 120,000 stars for signs of planetary bodies in orbit around them, in addition to studying the stars themselves. There’s a BBC story here, with video, more figured and images, and links to other sites, such as this condensed mission guide. The Proteus platform in the diagram refers to that fact that this is but one of a series of craft in the “Proteus” series, the platform itself being the design of the core containing the instrumentation and control systems of the device.

Attack of the Clones?

cloned cowsNo, probably not, but we are probably in for a battle. The FDA is said to be about to announce the approval of using cloned animals for food. The announcement will be on Thursday, but there are several news reports about it already. Here is a link to an AP article written by Libby Quaid. (I also borrowed from that article the picture -left, by Chris Gardner- of cloned dairy cows Cyagra1 and Genesis.)

What will the battle be about? Well, Let’s get the fear-mongering (that opponents of this announcement will use to their advantage) out of the way first. If these were indeed clones in the purest sense of the word, produced in unquestionable circumstances, in an industry that did not already have several unsettling and dysfunctional features to it (see for example here) then there would be no issue. The bottom line is that we should be no more scared of clones than we should be of twins.

But it is not that simple. According to the article to which I pointed, here are claims -backed up with documentation- (I have not read the research, so am merely reporting that it exists) that the cloned animals are not produced in a manner that would be acceptable for the production of animals by other means -there are still many deaths and deformities in the process, and these birth defects are still not fully understood.

Carol Tucker Foreman, director of food policy at the Consumer Federation of America, said the FDA is ignoring research that shows cloning results in more deaths and deformed animals than other reproductive technologies.

The consumer federation will ask food companies and supermarkets to refuse to sell food from clones, she said.

“Meat and milk from cloned animals have no benefit for consumers, and consumers don’t want them in their foods,” Foreman said.

That alone might not be so terrible, you’re thinking, but the big thing (to Click to continue reading this post →

Really Old Stars?

One sees them a lot around here, given the town I’m in, but that’s not what I’m talking about.

There’s a Spitzer telescope press release about the possible discovery of the most early stars detected to date. These would be the very first stars to have formed in the universe. Remembering that the universe is 13.7 billion years old, pause for a moment to be impressed by the claim of Kashlinsky, Arendt, Mather and Moseley that these stars appeared less than a billion years after the big bang. You should also read some discussion in John Baez’ recent post. [Update: See remarks from Ned Wright at the end of this post.]

The new milestone on the timeline of the universe’s history, if this is correct, would look roughly as in this image (from the press release):

james brown image from concertshots.comOh, man ! Right now I’m seriously jammin’ along to NPR’s Fresh Air. Why? It is a retrospective on James Brown (you’ve heard the news, I imagine). Terry Gross (the show’s presenter) has lined up a 2005 interview with him, and also has cut in interviews with Bootsy Collins, Maceo Parker, etc. It’s all about his music’s history – the influences, the influenced, the ideas, the groove, the politics, the movement, the Movement, and so much more.

If you’ve not listened to James Brown’s music before, this is a good chance to learn what it’s all about. (Image right from concertshots.com.)

Heat Engine – The Original Hot Boy Band

Read about the long lost history of Thermodynamics over at Lounge of the Lab Lemming. There you’ll find out about the 19th Century Boy Band Heat Engine, whose original membership was:

  • Rudolf Clausius: bass
  • Emile Clapeyron: percussion
  • Sadi Carnot: vocals
  • Hermann Helmholtz: calorimeter

… and much much more.

In this history, the laws of thermodynamics were motivated by the same old thing that motivates so many things, it seems: Attracting the opposite sex. Why am I not surprised?

CMB Anomalies

CMB anomaliesYoung1 Bee does it again, this time with an excellent post entitled “Anomalous Alignments in the Cosmic Microwave Background”. You’ve heard a huge amount about the success of modern precision cosmology, driven so muchn in recent times by the extraordinary data from the Cosmic Microwave Background measured by experiments such as WMAP. Well, there are some very interesting anomalies in the CMB data that have yet to be properly understood, and Bee discusses them in her post. I’ll do no more than send you over there to read it and join in the discussion if you wish. Nothing wrong with a bit of Cosmology conversation during the holidays.
