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
My always-ignored advice to anyone studying for exams is that the best thing you can do the night before is get a good night’s sleep. Long study periods long before the previous night should have been used to build up your skills and knowledge. Late-night cramming at the expense of being fresh and having your wits about you in the morning is not really going to help much, if at all. (Heh… long study periods….call me old-fashioned.)
On this very matter, Yvette (one of our regular commenters here) has outdone herself once again with her literary skills! Here is part of her seasonal (as in finals season) poem:
The Night Before Finals
By Yvette Cendes
T’was the night before finals
And all through the dorm
Crazed cramming and panic
Was quite the norm.The students were restless
And none touched their beds
While theorems and formulas
Danced in their heads.With textbook in hand […]
Well, I don’t like this whole “nerd” business, a term that’s somewhat about marginalizing people who actually care to devote themselves to something*, but I lightened up for a while to take this test**. As you can see from the score on the left, I get to keep my membership card. I might even get to sit on some committees in the club. But I don’t think I get to chair any, and certainly won’t be president. That’s probably a good thing.
Why do it? Some of the questions are just really funny! […] Click to continue reading this post
Oh boy. I laughed very loudly in my office at this in many places. I had the door closed, mercifully. I’m sorry, but most of you won’t get this, but I need to let the relative few who’ll find this hilarious know about it. So scroll on down to another post if you’ve no idea why this would be funny for you. Basically, you have to be into Radio, and moreover into BBC Radio. Quite a bit. If you’re familiar with it (especially Radio 4 and Radio 3) then please please please listen to this new program: It’s called Listen Against. It is a remarkably good and hilarious parody of Radio 4 and a host of other […] Click to continue reading this post
Yesterday, on (one of) the biggest shopping days of the year, I went… shopping. Insane, I know. Oddly enough, it was not a disaster. After an hour or so the headache that usually develops (when I have to make so many decisions over prices and items of clothing and so forth) began to approach, but that was largely due to the barrage of Christmas Carols. I eventually found a way to see the humour in just how dreadful some of the treatments of various songs can be, and that kept me going a bit longer. The Mel Torme (“the velvet fog”) version of “Chestnuts Roasting on an…” (whatever it’s really called) has sunken to a new unanticipated low by having had a strangely irrelevant and mood-altering backbeat added to it for part of the song. I heard this in the Gap, which meant that I left rather hurriedly without buying anything because I was laughing too much. After three hours of this sort of activity in several stores, I came away with essentially one item. One. Sigh.
Anyway, where was I going with this? Well, nowhere in particular, but I thought I’d share my lunch scene with you. I was at Santa Monica for the shopping you see, and part of my agenda was to make the shopping bearable by having a late lunch down at the beach.
I’d packed a sandwich, brought a book and an apple, and everything. On my way, I stopped at a store I regularly stop at to get the best deal in Santa Monica – the aforementioned simple jam tarts. A dollar apiece. I got two. Dessert, you see. They packed them into the usual pink box, and after getting a cup of coffee next door I wandered down to the pier, past the pier, and walked toward the area where all the chess tables are set up. Chess players were there, including many of the regulars I’ve […] Click to continue reading this post
Surprisingly satisfying sound to it, that word… Bench.
Feeling a bit off the tracks, internally, in one way or another and so I’ve decided to opt out of Thanksgiving this year and spend some time hiding out on my own. Consequently, there’ll be no cooking post, I’m afraid. I’ll have to refer you to last year’s. However, there are other arenas of derring-do besides the kitchen. Today, Asymptotia goes down to the workshop…
I’ll probably be drummed out of the Theorists’ Guild for admitting this, but I can’t go for long without making or doing something constructive with my own hands. The mood to make something hit me hard the other day. Not long ago I began to eye various aspects of my office (at home) and try to understand why I only use it to pick up printouts, find a book on a shelf, and add to the giant piles of paper on every surface. I never sit in it and use it, and I did not know why, annoyingly enough. Well, I think I figured it out, and after making a series of investigations, and a series of detailed measurements, the solution is on order. I will report later. The solution (and some other projects I have in mind) will require some careful woodwork, and I’ve not really got a good working space for that, having mostly done all my woodworking on the ground, patio, steps, and other improvised places.
So today’s project was to fix this. The plan began with a spontaneous purchase (for […] Click to continue reading this post
Since everything seems to be degenerating all too rapidly into holiday mood (giant Santas and huge batteries of lights and so forth have started appearing in my neighbourhood1 … students are leaving early to go home for Thanksgiving…which is this Thursday, by the way), this year I’ve decided to give in rather than resist. So my first holiday act of the year was to let my class know this morning that I won’t hold a Wednesday class after all. They must agree to do the homework and other practice I assign, and to use that hour (when it comes) to curl up with and start a new novel of their choosing1. My second holiday act is to get everyone singing. Yes. Singing.
What shall we sing?
Well, Oliver Rosten has written a song that’s quite appropriate, since it is related to physics and mathematics, in a way. It’s about an aspect of the Department of Applied Mathematics and Theoretical Physics at Cambridge, so I’ll be listening out for especially enthusiastic singing from you readers over there (you know who you are), ok?!
I’ll steal the words from his site by way of explanation, followed by the song itself. The tune should be familiar to many. Let me/him know what you think in the comments (be sure to close your office door the first time around until you get the rhythm right):
By the way, don’t forget the Leonids over the next few nights, if you happen to be out and about. There’s no exceptionally high activity expected, but that does not mean you won’t see a few if you’ve a mind to look up. It’s at least a good conversation point … Click to continue reading this post
Well, that was a bit of an odd day. Let me explain.
An email and then a call with a producer at Comedy Central last week led me to the (historic) Hollywood Center Studios today. I was to do an appearance in a little comedy “bit” that will be part of a show to air next year. They wanted scientists for a fun piece, but I won’t say what they were doing with us since I don’t know if they’d like it revealed before airing (probably not). It’s a new show too, with some very well known and smart comedians on it. I’ll tell you more when I can. All I can say is that it looks as […] Click to continue reading this post

This was originally posted on Cosmic Variance on May 3rd 2006. It was a report on the Categorically Not! event that took place on 23rd April 2006, entitled “Really?”. I’ve decided to reproduce it here as a happy memory of the wonder that Artist and Educator Bob Miller brought into the lives of many. (See next post.) It was a marvellous event overall (probably my favourite Cat Not! event), with several excellent presentations, and so I’ll reproduce the post in its entirety (with slight corrections) to give you a sense of the evening. -cvj

Well, apologies to all concerned for taking so long to post this, but here it is. The Categorically Not! two Sundays ago was -as usual- extremely enjoyable and informative. This one was all about Illusion, in some sense, the theme being “Really?”.
We started out with a few opening remarks by Bob Miller, who specialises in what 
some might call “light art”. He’s well known for creating a large number of wonderful works using light and shadow, several of them forming the cornerstone of exhibitions in the Exploratorium in San Francisco, for example. Have a look at the “lightwalk”, linked here.
Bob did not talk much, because he wanted everyone to just play, learning from getting involved. And play they did. He’d been up all night preparing (with KC Cole’s help) various fun things for people to do (see the table in the picture above, for example). All simple, and all with a little printed explanation about what to do, and the operation of the thing they were playing with or effect they were seeing.

The photos record scenes from an excellent use of the Los Angeles Natural History Museum’s large exhibition halls after hours: Live music. (They’re not super-great – I only had my phone with me.)
A friend took me as a guest to a filming of Josh Ritter and his band for a TV show. Lots of Lovely Bones everywhere*, stuffed animals, loud (but not too loud) good music (I’d not really listened to Ritter before – hey, not bad at all), and free martinis on tap (surprisingly not watered down!) from Grey Goose. How could I not go?
(You can see the exhibit hall (North American Mammals, I think) with the activity in the distance between the bones of Mr/Ms Triceratops here.)
If you’ve never been the the Natural History Museum here before and you are in LA, please go along. It’s really very good indeed. As an incentive, you can go to the new spider pavillion and wander around with live spiders everywhere. (What’s that? That’s not an incentive? I see…Well, there’s lots to see besides rubbing shoulders with spiders, from dinosaurs, mammals and birds to wonderful gemstones and minerals…) I’m thinking of going to check it out some time, and maybe report back here on the blog about it some time.
This event is sort of typical of LA, in both good and bad ways. There are all these […] Click to continue reading this post
I don’t know if you’ve been watching the new PBS series WIRED Science, but I recommend that you give it a try. There was another excellent episode Wednesday night, covering topics as diverse as organ regeneration, neutrino oscillations, and research in supersymmetry (interview of Jim Gates by Zia). You can see video of lots of the segments here.
To my delight there was another excellent new short segment, called “Hack”, again done by Chris Hardwick in the studio. Recall I spoke about the “What’s Inside” pieces a few weeks ago. “Hack” shows you how to make something familiar, as opposed to just find out what’s inside something. In this one, Chris (who’s impressively very funny while he does the chemistry: : “a funnel…’cos it’s got the word `fun’ in it”) shows you how chemoluminescence works by demonstrating how to reproduce what glow sticks do! Here’s the video:
While I’m on the subject, there’s some news over on my other blogging gig, […] Click to continue reading this post
[Post reconstructed after 25.10.07 hack]:
The strange object pictured above is a rather nice demonstration of the “field lines†around a bar magnet. It is not a great photo (all my fault), but the demo is great. The designers suspended the tiny bits of iron in oil, inside a sealed chamber, forming a block. There’s a little cylindrical hole through the centre of the block (but still outside the chamber) that allows you to put a bar magnet in. This makes for a demo far more exciting than any shake-it-up snow scene: You shake block and the iron filings are all over the oil in three dimensions, randomly arranged. You then insert the magnet. They slowly but determinedly arrange themselves into the familiar pattern, in three dimensions. It’s great. (Why didn’t they have these when I was growing up?! I might have gone into science… Oh, wait…)
I was looking around one of our demo labs last week for things to use to demonstrate some of the principal effects of magnetism. The above demonstration was one of the […] Click to continue reading this post

Don’t forget the Orionids over the next night or two (peaking late tonight, the wee hours of Sunday morning). As the name implies, look for them coming from Orion, although even if you don’t know exactly where that is, you’ll see them almost anywhere you look in the sky if you’ve enough dark. Recall that Orion has those three bright equally spaced stars in a line, making up his belt. I spoke about this, and gave more directions about the Orionids in a post last year.
There’s a Space.com piece by Joe Rao with more discussion. About sightings, it says:
Expect to see few, if any Orionids before midnight – especially this year, with a bright waxing gibbous Moon glaring high in the western sky.
But moonset is around 1:30 a.m. local daylight time on Sunday, and that’s a good time to begin preparing for your meteor vigil. At its best several hours later, at around 5:00 a.m. when Orion is highest in the sky toward the south, Orionids typically produce around 20 to 25 meteors per hour under a clear, dark sky.
Today’s StarDate (as usual, read on NPR by the wonderful Sandy Wood) has a piece on it too. Here’s an extract from the transcript (written by Damond Benningfield):
A quick reminder. The show WIRED Science (that I mentioned earlier) debuts tonight! Notice also that the website with all the extra material is now live (and rather amazingly well designed -well done the New Media division at KCET), and – don’t forget – debuting also (and already live) is the new blog Correlations (I gave you the back story on that here). You can find a link to it from the site, or go directly here (but go look at the main site too). Please go along and say hi to us over there on our welcoming blog posts. And Tell Your Friends! (That includes you, science-oriented bloggers, it’s in a good cause!).
Here’s a teaser for the program, and one of the reasons I have high hopes for it. Here, they strip aside all the fancy stuff and just put a good person in front of the camera to get people thinking about something simple. This is a great thing when done well, and they’ve got the people who can do it. Here’s presenter Chris Hardwick doing a brilliant job of telling you what’s inside a simple everyday product in an entertaining way (link with transcript here, or play right here by clicking below): […] Click to continue reading this post
