Dark Matter in 3D

Have a look at this:

hubble 3d dark matter

What is it? It is an image of part of the three dimensional (see below) distribution of clumps of dark matter in our universe, produced by an extensive survey using the Hubble telescope. How did they produce it, given that dark matter is -by definition- not visible? They deduced the presence of the chunks of dark matter by looking at the gravitational […] Click to continue reading this post

Potential

Recall that a little over a month ago I reported about the Tesla electric car to you? In that article, I congratulated the car makers on their choice of name, and speculated about what other names might be used in the future when more car manufacturers get into the game. One of my favourites was the “Volt”. Well, today, GM announced a new electric car in development, and guess what they called it? The Volt! I was rather prescient, it seems! More on the announcement of the Chevy Volt at Newsweek (I borrowed the picture from there) and the San Jose Mercury News.

What will the Volt do? It is a hybrid, but the driving mechanism is purely electric. This is different from what other well-known hybrids do”: […] Click to continue reading this post

The New Plastic Revolution

The writing’s on the wall. Well, it really will be, and in several other places. The revolution’s very nearly here, you see. We’re on the cusp of it. It’s been talked about before, but it’s really here. Within a year or few we’ll be carrying around completely new devices based on this technology, and there’ll be all sorts of things in the household and office. You may have heard the buzz, but if not, I’ll say it here too. It’s all about microscopic electronic circuitry based on polymers that conduct electricity. The novelty here is the plastic nature of the resulting circuitry and devices that you can build, where I am using the word “plastic” in its descriptive sense – it is flexible and can take lots of shapes quite readily.

There’s a revolution on the cusp, not because this is hugely new (it is not, and the […] Click to continue reading this post

Just So You Know I’m Not The Only Nut In The Fruitbowl

share the road You may have read my most recent two posts (here and here) on commuting by bike (maybe combining it with bus, and subway as well, which is what I do most times – there are excellent express bus routes through the city: the Metro Rapid system). I’m not the only person cycling in this city. For more on cycling in LA there is a host of resources. There’s the Los Angeles County Bike Coalition for example, the Bike Kitchen, the Midnight Ridazzz, and many more activities and associations. There are maps of cycle routes and cycle lanes on the LACBC site too, as well as recreational bike paths.

Here’s a recent Los Angeles Times profile, written by John Balzar1, of Monica Howe, who is a major mover and shaker in the local bike and biking awareness scene. (I borrowed the photo, above right, from the article. It was taken by Al Seib.)

It’s very nice to read about people who are super-enthusiastic about the same issue. It is an uphill struggle, but I think I see more cyclists on the roads these days.

One thing that is mentioned a lot in the article and in other discussions of this sort is the safety issue. For what its worth, in my opinion the danger risks are often overstated, or perhaps not properly represented. While there are accidents due to careless drivers not paying attention, etc., I have to say that there’s not enough mention in these discussions of the far too many cyclists who are doing stupid things. I can’t help but wonder how many of those stupid acts contribute to the number of accidents that people count […] Click to continue reading this post

Categorically Not! – Movement

The next Categorically Not! is Sunday 7th January. The Categorically Not! series of events that are held at the Santa Monica Art Studios, (with ocassional exceptions). It’s a series – started and run by science writer K. C. Cole – of fun and informative conversations deliberately ignoring the traditional boundaries between art, science, humanities, and other subjects. I strongly encourage you to come to them if you’re in the area. There’s a website of past and upcoming events here. You can also have a look at two of the last two descriptions I did of some events here and here, and the description of a recent special one on Uncertainty that was held at the USC campus is here.

Here is K.C. Cole’s description of the upcoming programme:

“Movement: You can’t leave home without it. In fact, you can’t get anywhere without it—whether you’re trying to bring about political change, compose music, send a robot to Mars, or merely make your way across a room. You can’t even […] Click to continue reading this post

Science on TV – Having Your Say

Recall that I told you about the pilot for the upcoming show Wired Science in an earlier blog post. It airs today, (Wednesday, January 3) on PBS. It was made by KCET here in Los angeles, and as you may recall from the post, in August I learned some interesting things about the context in which the show sits. It is rather interesting. It’s all part of a head-to-head competition, or “experiment” as PBS are calling it.

You see, there are two other shows being piloted on PBS over the next couple of weeks too. One is Science Investigators, made by WGBH, Boston, and the other is 22nd Century, made by Towers Productions (I think). They are three different takes on a science TV show format. The casting, scripting, presentation… all these things vary a great deal.

They’re really trying to come up with newer, more accessible formats, with the aim of getting science out there to the general public. This is a great thing. Only one show will “win”, sadly. The prize is the go ahead to make more episodes, and have them air on PBS. The judges…. this is the important part… The Judges are YOU. Go to the PBS site […] Click to continue reading this post

Science Sense

I learned just now that there’s a charity in the UK called Sense About Science. From their website, I read:

Sense About Science is an independent charitable trust. We respond to the misrepresentation of science and scientific evidence on issues that matter to society, from scares about plastic bottles, fluoride and the MMR vaccine to controversies about genetic modification, stem cell research and radiation.

Our recent and current priorities include alternative medicine, MRI, detox, nuclear power, evidence in public health advice, weather patterns and an educational resource on peer review.

This is good to hear about. Recall earlier that I was wondering aloud whether there was anything in the UK that is equivalent to the USA’s Union of Concerned Scientists, or the recently formed Scientists and Engineers for America. This is not really an equivalent organization (they consult with scientists, rather than being a scientist-run organisation for example, and they seem relatively disconnected from the makers of public policy, where a lot of the real battles are to be fought), but they are at least swimming in the same waters.

I learned about them because they’re in the news today. ‘Tis the season for […] Click to continue reading this post

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 bit […] 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 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: […] Click to continue reading this post

What is it with Saucers?

No, 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

lorenz manifold

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
