Comments Off on Categorically Not! – Science Goes Hollywood

Reza Aslan at Categorically Not!The next Categorically Not! is on Sunday January 27th (upcoming). The Categorically Not! series of events that are held at the Santa Monica Art Studios, (with occasional exceptions). It’s a series – started and run by science writer K. C. Cole Reza Aslan at Categorically Not! – 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.

Here is the website that describes past ones, and upcoming ones. See also the links at the end of the post for some announcements and descriptions (and even video) of previous events. (Above right and left: Reza Aslan speaking on the origin of various ideas in Religion at the event entitled “Beginnings” on 16th December, 2007. Click right one for larger view.)

The theme this month is Science Goes Hollywood. Here’s the description from K C Cole:

Despite our prejudices to the contrary, Hollywood and Science have a lot to say to each other. Take special effects: Nothing Disney dreams up can […] Click to continue reading this post →

Lousy Book

louse by louis de vosWell, actually it sounds like a really lovely book, and the louse to the right (among other creatures) is featured. (Photo by Louis de Vos.)I read about it in a splendid little article in LA Weekly today on the bus home on a wonderfully rainy afternoon here in LA. The book’s all about the common creatures in our homes – “bugs” of various sorts, and the LA Weekly article by Gendy Alimurung is mostly an interview with the authors, Joshua Abarbanel and Jeff Swimmer. The book is called “A […] Click to continue reading this post →

Asymptotia Attacked!

Sigh. It was too good to be true. Hours after updating the site (and feeling pleased with myself) because I caught a whiff of something threatening it, a blistering attack came along, in the form of essentially a denial of service attack from hundreds of separate machines/robots all from the same referring site. (See Josh Davis’ report on such things for the Wired Science TV show last year. Video here.) I tried everything I could think of to get rid of it and could not win. In the end, my hosts shut down my account and suspended the domain (fair enough – actually might have helped), and (not cool) one of their fine technical support people blamed me for the problem […] Click to continue reading this post →

Not Science Fiction

Anti-matter. Seeing the previous word, you immediately glance back at the title, right? Strangely, it has been 80 years since the discovery of anti-matter, and we use it routinely in our technology. Nevertheless, anti-matter is still thought of as something from science fiction (and mostly bad science fiction at that).

dirac_equation.jpgIt all goes back to one of my favourite theoretical physicists, Paul Dirac, and you might like how he found it (roughly). He essentially did it by […] Click to continue reading this post →

Put Yourself In Their Shoes

alan alda and kc cole

Excellent evening on Wednesday night. As I expected, KC worked her magic and steered the conversation in many interesting directions, with Alan Alda turning out to be – not unexpectedly – quite the character. I suspect that it was recorded (on video) and so I will update this post or do a later post with a pointer to it later. Alda was swamped by people buying his book and getting is signed and so forth at the reception. It was great to see such a good attendance at this Visions and Voices event all about science and the arts – very much in the spirit of what this is all supposed to be about.

Messages from Inside

By | | , , ,

Inside meaning the inner part of the Solar System. Messages meaning the new pictures from MESSENGER spacecraft.

MESSENGER is short for MErcury Surface, Space ENvironment, GEochemistry, and Ranging. Now you and I know that they spent a bit of time coming up with the unpacking of the name, wanting of course to have the name MESSENGER because that’s what the Mercury of mythology was – the messenger of the Gods, among his other duties. Nice. However I’d have been really impressed if they’d managed to call it QUICKSILVER, and found a way to unpack that – any takers?

Anyway, I digress. In more news showing the triumph of the wisdom of relatively cheap unmanned exploratory craft, MESSENGER sent some wonderful pictures of Mercury this week, along with lots of other scientific data that will help us learn a great deal about the innermost planet. Here’s the one that’s been going around a lot (click for impressive larger version):

Lecture One

lecture notes

So it is that time. A new semester is upon me, and a totally new course to deliver. Today was my first day back on campus after the break (at least during a regular working day).

Sunday saw me sitting down (in the newly completed study) thinking about how I was going to structure the course. This usually has me sitting with the textbook, a pen, a hand drawn calendar on a big sheet of paper, and a frown on my face trying to figure out roughly what topics I will cover, how many lectures I will devote to each, how many class worksheets (see earlier post) I might have, when the midterms will be, and so forth.

What I am teaching? Why, only one of my most favourite topics to teach in the entire […] Click to continue reading this post →

KC’s always so good at steering these conversations, so while I’ve no idea […] Click to continue reading this post →

Two Rings

Now have a look at this object (and its enlargement on the right):

double einstein rings

What is it? It’s a double Einstein ring! An Einstein ring is formed by gravitational lensing – the bending of light from one object by the gravity of another object – and is typically formed when a distant galaxy lines up with another, closer galaxy. The result is a rather nice ring shape.

To find a double Einstein ring is rare! In fact, this is the first one that’s been announced. Not only is it novel, it can also use used to do a good deal of science, such […] Click to continue reading this post →
