This is a quick note to point you to the Women in Physics conference (aimed primarily at undergraduates) being held at USC again this year. It’s on Saturday and Sunday coming. It looks like another excellent program (see here), so well done to the organizers for keeping going what Amy … Click to continue reading this post
Tomorrow afternoon at 4:00pm there’s be an interesting conversation on campus for sure. It’ll be between the science writer and journalist KC Cole and the actor Alan Alda. He’s such an interesting person, and (among other things) currently presents Scientific American Frontiers.
KC’s always so good at steering these conversations, so while I’ve no idea […] Click to continue reading this post
Now have a look at this object (and its enlargement on the right):
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
This is a quick note to let you know that today’s Science Friday will feature the Science Debate 2008 (which has been nicely gathering momentum since I blogged about it): Friday, January 11th, 2008 Hour One- 2pm EDT The Call for A Science Debate “Should the presidential candidates participate in … Click to continue reading this post
Being a loyal fan of Scottish single malt whisky, I never thought I’d be blogging about Irish whiskey, but this is why we get out of bed in the morning – we seek the stuff we can’t guess*.
So I was going to point out to you an amusing distraction. The series of radio ads for Jameson Irish Whiskey that you can listen to here. There’s one featuring a physicist, you see, and a friend of mine sent me the link for that reason**. There’s the idea of attraction, and so gravity is brought in by the ad man trying to use the concept to sell the product, and the physicist is obviously not having it… a short bit of fun play between segments of some program on some station somewhere or another. I can see that they’d work rather well. Have a listen.
That was going to be it, until I found another – real – physics connection. Turns out that Guglielmo Marconi – he of the use of electromagnetic waves for telegraph communication, Nobel prize, and so forth – is the the key to the connection. Do you know what it is?

… but pass it on a retake!
While quickly building an ad hoc washing line pulley assembly from a bag of hooks, eyes, and pulleys, and a 2×4, I put this together at first (blotted out some background for privacy of myself and neighbours – click for larger view):
Huh. Does not want to hang level. Why? A tenth of a second after the thought, I burst out laughing loudly at my error. Ironic since I love teaching about pulleys in basic physics, and for some reason students are scared of pulleys. (Not as scared as they are of torque (why?), but scared nonetheless. I try to help them overcome those fears.) I made an obvious mistake. (Do you see it?)

It all began over dinner on Thursday night, before the rains began. Some of us met up at Ciudad (a favourite place of mine to eat in downtown Los Angeles, primarily for the mojitos) and the began to get to know each other in person, as opposed to online. I’m talking about the Correlations bloggers, and members of the team who work on the entire Wired Science website (which is excellent, by the way) with which Correlations is embedded. I met most of the latter group at various KCET events (the first screening of episode 1, the wrap party a few weeks ago I never got around to blogging, etc). This however, was the first time I got to meet Sheril Kirshenbaum, although we’d got to know each other so well online I have to say that it sort of felt as though we’d already met. Co-blogger (and show producer) Damon Gambuto arrived a bit later – I’d met him before at the party. The other bloggers coming from out of town to the meeting, Tara Smith and Michael Tobis, I would meet the next day since Michael’s flight was coming in late, and Tara was not feeling well. Tamsin Gray, being stationed in Antarctica, was not going to attend. Of the show host co-bloggers, Chris Hardwick (who I’d already met at the wrap party) would be there next day too. Ziya Tong was away.
Here’s a shot of some of us chatting at dinner (see also Sheril’s thoughts on this here):
Damon Gambuto is second from left, and there’s Sheril Kirshenbaum and cvj on the right – click for larger view. There’s also Liz on the left, and Philip Dunn in the centre, both from New Media.
The main purpose of all of this from the bloggers perspective was simply to meet and […] Click to continue reading this post
Has the ring of a Harry Potter novel’s title, doesn’t it? Well, it’s about physics. The history of the physics of cold, particularly its extremes. It’s a TV show on PBS’ Nova (based on the Tom Shachtman book of the same title), to appear this week, and it looks rather good! You can see the PBS website for it here. The good news is that this program has been a while in the making, with lots of physicists involved behind the scenes to get it right, so I’ve got my fingers crossed that it will not just be entertainment for the moment, but actually a rather good information resource (as well as being entertaining – the two are not mutually exclusive). It first airs on January 8th and 15th (there are two hours, one on each day). There are preview videos to look at […] Click to continue reading this post
This might be a bit late for some of you, but since it’s rather good I’ll mention it anyway. Recall that I was discussing various “top n of the year†lists that came out in various publications over the last few weeks. Well, I thought that the Physics World one, a list of twelve (one for each month), was rather nice. I saw it only recently*, and […] Click to continue reading this post
On Space.com, Joe Rao talks about comet Tuttle’s return, and reminds us that comet Holmes (see here and here) is still worth a look. In fact, he gives a little bit of history of Tuttle, which is worth a read.
He also tells us, in another story, about the Quadrantid meteor shower. The what? I hear you cry. Well:
The meteors are named after the obsolete constellation Quadrans Muralis, the Mural or Wall Quadrant (an astronomical instrument), depicted in some 19th-century star atlases roughly midway between the end of the Handle of the Big Dipper and the quadrilateral of stars marking the head of the constellation Draco. (The International Astronomical Union phased out Quadrans Muralis in 1922.)
(Cartoon shaking of fist… “Curse you, IAU!!!”) (Er…. remember Pluto.)
This is not the most well known of meteor showers, but this year it was set to have […] Click to continue reading this post
It’s time to do that other thing that people do at this time of year: Reflect upon the year that is coming to an end. People start doing highlight programs on the radio and tv, surveying the year of blog posts on blogs, and so forth. Also, various science editors start doing their “top science stories” of the year. They are usually smart enough not to try to rank them, but even so, I do find myself wondering about what makes it to the lists and what does not. I’m particularly curious as to the nature of the discussions that must have taken place in order to compile the list.
Of course, science does not work to a tidy calendar (even though that would be rather nice and neat for our funding agencies), and – more significantly – it is often very hard […] Click to continue reading this post
How about a bit of chemistry? My Correlations colleague Chris Hardwick, one of Wired Science’s presenters, did another excellent demo on the show. This time he did it with chemistry teacher Chris Schrempp, who showed us how to make nitrocellulose in a few simple steps, using common cellulose sources such … Click to continue reading this post
While I’m on the subject of art and science, I should point out that QMUL’s David Berman told me about an exhibit of drawings by scientists on various themes in physics. He was looking for contributions too (although it may be too late now, I’m not sure). The website is here. He told me a while ago, and I apologize for neglecting to point it out to you sooner (for a while I was sure that I’d done a post on it, but cannot find one).
David said (back in October): […] Click to continue reading this post
Over on Correlations, I posted about the second of the two pieces I was considering as exhibits for some of my thoughts on science and art for Seed magazine. Recall that my first post on this – about the piece and text that I finally submitted for publication – was done a few weeks ago. The theme I brought out there was “transcendence”. For […] Click to continue reading this post
A little over a month from now, Mars might be hit by an asteroid! There’s a 1 in 75 chance (due to uncertainties about the exact trajectory), according to the people tracking the object’s progress right now. The 50 metre wide object is due to pass within 300000 miles of Mars at about 6 a.m. EST (3 a.m. PST) on Jan. 30, 2008. Quoting quite a bit from the press release from JPL/NASA: […] Click to continue reading this post
