Still So Far To Go

Sometimes one deludes oneself into thinking that progress has been made on some important social issue, and then out of the blue, there’s a reminder of just how far things still have to go. Check out this post - supposedly a report on the contents of a physics seminar given by a woman - on the blog “A Quantum Diaries Survivor”, and get a reminder of what women in physics are up against. Near the beginning of the post he spends one of the longest paragraphs of the piece talking about how her hair was done, how fit and attractive he thinks she looks, wondering whether she works out…(!) It’s so completely awful to do this sort of thing and he does it so spectacularly completely that I actually thought it was meant to be a parody of some sort! From his comments in response to people pointing out the inappropriateness of it, it turns out that he really does not get it at all. Not a bit.

It is really sad. It is so embarrassing too, when anyone female shows up in a physics context and guys just start behaving like they’ve never seen a woman before. That silliness alone is simply embarrassing, but this is quite a bit worse I would say, since it is damaging to the cause of women in the field.

I really shouldn’t go on, and I will risk sounding preachy and self-righteous (and I’ll just get yelled at and nobody will learn anything) but it’s important, so I will try some words:

Of course there are contexts in which we can discuss things about each other that take note of (even celebrate) our differences in gender, race, and so forth. I’ll be so bold Continue reading ‘Still So Far To Go’

They’re Out There (Probably)

alien from the movieLet’s talk about aliens. I don’t mean people coming across the borders of whatever your country happens to be (although I did giggle a decade ago when I was given an official “alien number” by the powers that be back then - though I always regretted bypassing the “alien with extraordinary ability” status that the O1 visa gives you), I mean living creatures from beyond planet earth (it’s also interesting to consider the possibility that the seeds for life on earth may also have come from elsewhere).

It’s one of my favourite topics to consider, which is why I like to follow a lot of the remarkable things we are learning about our neighbouring planets (and other bodies like moons, asteroids, comets, and, yes minor planets like our old friend Pluto), and of course the ever-increasing variety of extra-solar planets (the ones we are discovering orbiting other stars). Overall, it gives one the sense that it is overwhelmingly likely that we are not alone (to use the tired old phrase), which to me is tremendously exciting.

I think we’ll find lots of compelling evidence that there’s lots of simple life on other bodies relatively soon, and I think that when people on the street hear of this, they’ll find it interesting enough. But I suspect that this will completely different to an Continue reading ‘They’re Out There (Probably)’

Total Eclipse of the Moon

nasa total eclipse informationHow come there’s no song with this as the title? Sung by someone with a gravelly voice…. (Sorry, semi-obscure ’80’s music reference.)

Anyway, yes, there is one later tonight (more properly, early in the morning on Tuesday). For West Coasters, the interesting phase starts at about 1:50am, and it’ll last for well over three hours, going total at 2:52am and coming out of total at 4:22am. Please make the appropriate adjustment for other timezones.

This is good news for me, as I’ve got eight hour jet-lag from flying back from England Continue reading ‘Total Eclipse of the Moon’

Switching

Back in LA, and down at the USC campus. Good to be back! Click below for larger view.

campus overhead from google maps Well, it is the first day of the new academic year’s teaching cycle. I’m here in my office at 7:30am (the power of jet-lag) and somehow have to switch my mind back firmly onto teaching and other matters. It’s always tough to do this, since there are always lots of intensely interesting research issues that continue on my mind from the Summer, and I know that some of those will gradually begin to fade (if I am not careful) as my other duties take up so much of my day to day. My first class (part one of the upper level electromagnetism course) is at 10:00am, and I want to plan out the structure for the whole semester, and write a syllabus to hand out and discuss. As well as the first lecture, of course. I’ve not taught this part of the cycle before, and so I’ll have to be writing new lecture notes.

I want to try some new things this year. In particular, I’ve become increasingly Continue reading ‘Switching’

Congratulations Brian May!

brian may receiving his phd from paul nandraFor what? The story is here. Ok. Full disclosure - I was quite a Brian May fan as a teenager, and as a physicist in training while at Imperial College, London. Now I was going to do a long post about playing electric guitars, building electric guitars (because I was into electronics, physics and music, not because Brian May did it too), analyzing his guitar solos, endless listening to Queen, endless teenage arguing with anyone who would engage about why he was a much better guitarist than [pick the flashy guitarist from some other rock group], probably permanently diminishing my hearing a bit at two huge Queen concerts, and maybe best of all …practicing music with my friends in the same room (it was said) over in Beit Quad that Brian used to use for practice in the days before Queen began! That was quite a thing for me back then. Here’s a little interview with him about his Imperial College days from the IC student newspaper Felix

There would have been pictures of the guitars and so forth, a clever post title playing Continue reading ‘Congratulations Brian May!’

Exploring QCD in Cambridge

exploring qcd sign

So the conference here at the Newton Institute in Cambridge is simply marvellous. I’m so glad I came, and so happy that I was invited to attend and make a contribution to it by giving a talk and having discussions. It’s a rather splendid combination of experimentalists, phenomenologists, and various hardcore theorists of various sorts, and there are ideas just flying around and bouncing off the walls. The title is “Exploring QCD: Deconfinement, Extreme Environments and Holography”, (it’s organized by Nick Evans, Simon Hands, and Mike Teper) and the focus is very much the fascinating nuclear physics of heavy ion collisions at the RHIC experiment at Brookhaven, and the experiments to come on heavy ion collisions at the LHC at CERN. The latter is an aspect of the physics to be done at the LHC that you don’t hear about much because it is sidestepped in favour of discussions about the Higgs, origin of mass, supersymmetry, theories of everything - such as strings, microscopic black holes, extra dimensions and all that other good stuff. (See earlier discussions here, here and here.)

Well, the great thing is that there’s been plenty of discussion of black holes, extra dimensions, strings, and so forth at the conference because of a great deal of promise of its relevance to nuclear physics. It’s been right alongside the discussion of experimental results, and other theoretical approaches such as work on computer simulations of aspects of QCD (”lattice QCD”) and studies involving other techniques. There’s very much a spirit of open-minded exchange among all the various parties Continue reading ‘Exploring QCD in Cambridge’

The Scary Universe?

Ok, there’s “The Elegant Universe”, and “The Ambidextrous Universe”…. even “Stephen Hawking’s Universe”… and so on for these titles. But how about “The Scary Universe” or “The Dangerous Universe”? (Personally, I wish we’d just stop with the whole “The fill-in-the-blank Universe” stuff, so I probably should have not written this first paragraph.)

Well, I myself don’t think of the Universe that way, but tonight (at 9:00pm) the History Channel will be presenting the next show in their series (called “The Universe”), which is about (they say) the Most Dangerous Place In The Universe”. It looks as though it will be a survey of various places where a lot of very energetic activity is taking place, powering some of the most powerful phenomena we’ve ever seen, such as quasars, magnetars, and so forth. So black holes will feature quite a bit, I imagine, and although I probably should not really be telling you about it before I’ve had a chance to see it (recall my remarks about the windy shooting conditions), I think (I’m not sure) that I’ll be making an appearance as one of the contributors. (I did not get caught off guard this time.)

The whole “dangerous” motif is a sort of deliberately sensational way of presenting Continue reading ‘The Scary Universe?’

Brain Building

  brain from http://www.simpsonstrivia.com.arI’ve been sitting here for the whole evening building a set of slides for my talk here at the Cambridge conference (that I still have not got around to telling you about because I’ve been, well, attending it). My talk is at the start of the Wednesday session and so I’m starting early (yeah, I know) so as to build up all the introductory slides with the fancier graphics to lull the viewer into that comfort zone before bombarding them with technical results. You may well know the sort I mean. (image above right: click-to-enlarge-able “scan” of Homer Simpson’s brain, which I got from here.)

Anyway, I was sitting here thinking that what I could really do with right now (what with the jetlag, the sitting through five one hour talks - all great) is a rapid hike up to the top of Runyon Canyon or up to the top of Mount Hollywood in Griffith Park - two of my favourite pick-me-ups (or is it picks-me-up…?). This would get the blood flowing and give me that jolt I need to stay smart and alert for a few more slides before packing in for the night (and then panicking tomorrow that I did not do enough). All of this was running through my head when an email arrived* with this article about how exercise can boost mental function - actually promote the growth of new neurons.

Live Radio Footie Film Fun

football soccer ballradio dynamoSo you’ve already read my opinion about the Bourne Ultimatum after I returned from seeing it on the opening night - (In short, it’s just brilliant!) Well here’s something related that is rather funny, especially if you are a football (soccer) fan, although that is not necessary (I have little or no interest in it myself).

If you don’t already listen to Mark Kermode and Simon Mayo every week (most conveniently via their podcast), let me say right away that you should, since it is just an excellent and often highly entertaining discussion of film and movie releases. As a film reviewer, Kermode is not as good with words as, say, the New Yorker’s Anthony Lane (although it is not a fair comparison - the media are different), but his rants can be just great to listen to when he truly hates (and occasionally loves) something -whether you agree with him or not. Simon Mayo is sometimes thought of as his sidekick in this duo, but he’s really the anchor of the whole thing (and often the pragmatic link back to the everyday that keeps the whole show rooted), and from time to time the focus shifts to him. He’s also into his sports, while Kermode is not, which also makes for an amusing backdrop since the broadcast (on Radio 5 Live) is usually done live from some sporting context or other, which takes a sort of backseat role while they talk about movies. Anyway, it is an excellent podcast to listen to every week. I highly recommend it. You can find it on iTunes. (They also have started doing occasional video podcasts too, but the thing to go for is the radio show - another convenience of it is the fact that you can keep the podcast until after you’ve seen the films if you like (this is what I usually do - I mostly prefer to not hear anything about a film before I see it), and then listen to it and shout at Mark if you so desire.)

film roll images from usdojAs I mentioned, Mayo is a big sports fan, and his team, Tottenham, apparently got slaughtered by Crystal Palace and are now at the bottom of the premier league (can you tell I’m faking this and I’ve no idea what I’m talking about?) The next day, he’s interviewing (not with Kermode though) the director Paul Greengrass and the actor Matt Damon (both of the Bourne Continue reading ‘Live Radio Footie Film Fun’

101

mark bittman 101 coverHere’s something to shake up the cooking doldrums. Rather than bring you a report on one of my own efforts in the kitchen (and rest assured there’ll be more to come), I’ll step back and let you look at 101 ideas from a master. Mark Bittman, the food writer behind (among other things) the column “The Minimalist” for the New York Times, is extremely good at finding ways of producing more (in terms of taste) with less (in terms of substituting less costly ingredients while making a version of a more fancy recipe).

He’s recently tackled another cost factor: time. The claim (I have not tried any yet) is that these are ten minute preparation time recipes. This might be perfect for that busy schedule you have going there, or just a welcome shortening of hot kitchen time during the remaining long Summer days.

Don’t turn your nose up at the substitutions (sometimes discussed in his column) and Continue reading ‘101′

Newton in Bronze

newton by Eduardo PaolozziI’m writing from the courtyard of a particularly fine and (to my mind) vitally important institution, using their (surprisingly) free wireless (which runs at a charmingly-then-frustratingly glacial speed) to pop up these images of a huge statue, entitled “Newton”.

It is by the sculptor Eduardo Paolozzi.

Any idea where I am?

So in SEED…

seed august coverMy hand hovered over the August issue of SEED last night in the magazine section of a bookshop. I was not really sure whether I was going to buy it or not, to be honest. Then I glanced through, and two things made me go for it. The first was seeing that there’s something on Chuck Hoberman. I love his designs and constructions, and am dismayed by the fact that they are not just everywhere in our cityscapes. The second was a photograph. There’s some extracts from the collection of photographs of Nobel Prize winners taken by Peter Badge (beware, the cover makes you think that all 295 are in the magazine… there’s actually eight). I flipped to that part of the magazine and landed immediately upon the one of David Gross. It’s just great, in that it captures certain aspects of David just perfectly. There’s the intensely penetrating gaze of a great physicist combined with playful movie-star quality of the same. You end up convinced that if Hollywood was casting an actor to play the physicist, they’d have no choice but to use him to play himself.

There looks to be some interesting things in there to read. I see that there’s a piece on Science Journalism by Chris Mooney (also available here), and there’s what reads a bit like a commercial by Paul Steinhardt for his cyclic universe models with Neil Turok, and a discussion about the definition of life by Carl Zimmer. I hope it’s all as good a read as it looks.

My Springfield Persona

(I usually wear plain things with nothing written on them, but I suppose this particular design will do, for fun! Also, I could not really find the right hair.)

So what’s yours like? (Email me them and I’ll post them in the comments if you like. Or give a link to one on your page.)

P.S. The movie? Oh, it’s a pretty good extended Simpsons episode. I don’t know if it qualifies as a movie to see in the cinema, but then there’s an awful lot of really bad stuff out there that supposedly qualifies and can’t hold a candle to even a half hour Simpsons episode. Fun with a group out for a lark, I’d say.

Stargazing

(Shooting stars, that is. In other words, meteors. I’ll get to them eventually [or jump].)

runyon canyon bench

The evening started with a 10:15pm movie at the Arclight. I saw the excellent biopic “Talk to Me”, (all about Petey Green and his manager Dewey Hughes) which arclight cinemashappened to star two actors whose work I like a great deal, Don Cheadle and Chiwetel Ejiofor, who both seem to grow and get better and stronger with every performance. I could be very wrong, but they’re also both among that (much) shorter list of actors who seem to me like people it would be interesting to get to know and talk to as well (missed a chance earlier this year with the latter, who was rumoured to be one of the people they were trying to get to take part in that New York shoot for King Magazine I told you about here and here).

Then, at 12:30am I wandered over to my “local” (well, they treat me like one, which is good), and favourite English pub outside of England - the Cat and Fiddle. Said hi to and chatted briefly with the guy at the door (about Stephen cat and fiddleDonaldson books, of all things) and then ordered my customary thirst-quenching Hoegaarden and sat in the lovely courtyard for a while, reading some detailed notes of a series of what turned out to be startlingly excellent computations by my student Jeff Pennington. (Well, I don’t know if I should not call him my student any more. He’s graduated now and is off to do graduate work up North.) The Cat was relatively quiet (as it can be late on a Sunday night - it’s a very conservative town when it comes to staying up late; my theory is that it is partly because of all those early starts for shoots - and everybody seems to be connected to the Industry in some way), although I did get treated to the conversations of a group of people at the table near my bench. It seemed that all of a sudden, I was immersed in an episode of Entourage. The five women, dressed in severe (for a Sunday night) regulation “high powered 30-something person out on the town in Hollywood” outfits - more of the scary heel height and mercifully less flesh than the 10 years younger equivalent - seemed to be unabashedly discussing their various liaisons with members of the opposite sex, and two of the men from the group stepped aside (in my direction) to have a conversation about “the deal”, where one guy seemed to be seeking reassurance that he could pull off asking someone for 60 million. Ah, yes. It’s good to be back. Been several weeks since I intersected with this stuff.

The next stop - meteors. There’s nothing like a romantic evening under the stars - even if it’s a solo outing. I went to Runyon Canyon Park of course, getting there at about 1:45am. As I’ve mentioned before, it is another of those LA gems that most Continue reading ‘Stargazing’

MacArthur Park Theatre Event

Since, once again, the temperature is knocking on the door of insane outside, I’ll sit here on the sofa indoors for a while and tell you about the really fun thing I was doing earlier today. Back when it was much less hot.

MacArthur Park Theatre EventThe mission: First show up at Mama’s Hot Tamales Cafe. (So since at the very least, ridiculously tasty tamales are involved, clearly anything beyond this is just a bonus.) This is located across 7th Street from the South side of MacArthur Park, just West of Alvarado (map link).

Next, after saying hello to the friendly peopleMacArthur Park Theatre Event who are happy to see that you showed up for the event (a friend of mine and I were the first to show up), you sit at a table for a little while and read six plays. Don’t worry, since the average length of one of the plays is less than a page, so it won’t take long -and they’re all rather good!

MacArthur Park Theatre Event

Next, you go outside, cross the road, and spend some time in MacArthur Park. Why? Well, it is park with a bit of a bad reputation that is seriously underused and under-appreciated by many, so that’s a good reason right there…

…but the main reason for this visit at this point in the mission is to wander the park and see if you can spot some of the performances or, as one woman put it, Continue reading ‘All The Sweet, Green Icing’

Over the next few nights, you should have a good chance of seeing some of the Perseid meteor shower. They’re going to put on a rather splendid show this year, I hear. From the NASA news site, I’ve grabbed a a diagram of the region of the sky (containing the constellation Perseus, of course - that’s where they’ll seem to be coming from, and so that’s what gives them their name) that you ought to be looking toward. (The red dot is not a star, but the central point of (apparent) origin, and the red lines are some example paths of the streakers that you’ll see):

The Universe On TV

Something funny happened to me last night. I was reviewing some television programmes that my system had recorded earlier, by fast-forwarding through them. In particular, I was skimming (I’ll admit) through an episode of a series that I was wondering whether to do a quick blog post about, in order to remind you to watch it. It’s the History Channel’s venture into science programming called “The Universe”, which has been running for some time now. Well, I was zipping through the one about stellar evolution called something like “The Life and Death a Star”…. and someone familiar popped on and off the screen. It was me. Took me a few beats to register full recognition, which was amusing.

I’d forgotten that I was to appear in this episode. Or, better put, I was not aware I would be in this one. I thought the ones I contributed to would air later, like next month or something. I thought there was a separate episode on neutron stars, but I see now that they included it all in an episode about the whole life of a star, which makes sense. (I chatted a bit about the filming of it in an earlier post.)

Anyway, as I was going to say (whether or not I was in it) was that it’s a nice series so far, and so consider having a look at it. If you have not been watching it, I imagine Continue reading ‘The Universe On TV’

Supporting the STEM

Your opinion is needed.

The National Science Board at its August 8, 2007 meeting approved a draft “national action plan” for improving the quality of elementary and secondary education in science, math, technology and engineering and ensuring an adequate supply of teachers in those subjects. The plan, which will be available for public review and comment today on the science board’s Web site, calls for a range of actions by the federal government, states, and school districts, including creating an independent, non-federal National Council for STEM Education, establishing a new assistant secretary position in the Education Department, and developing strategies to pay teachers in those fields at “market rates.”

They are inviting public comments through August 30th, 2007.

Not a lot to say here except that you (as a member of the public who knows the value Continue reading ‘Supporting the STEM’

A Bit Jittery

endeavour at cape canaveral getting ready (AP photo)

Working by remote control, engineers at the Kennedy Space Center began pumping a half-million gallons of super-cold liquid oxygen and liquid hydrogen rocket fuel into the shuttle Endeavour’s external tank early Wednesday, setting the stage for launch on a space station assembly mission at 6:36:42 p.m., ….

(That’s Eastern time.)

…if all continues to go well, Endeavour’s crew — commander Scott Kelly, pilot Charles Hobaugh, Tracy Caldwell, Rick Mastracchio, Dave Williams, educator-astronaut Barbara Morgan and Al Drew — will begin strapping in around 3:15 p.m.

I always get a bit uneasy when one of these things is about to launch or land. This mission has added significance (re: Challenger), as you may know. There’s more in the story by CBS’ Bill Harwood, from which I quoted above. (See also an AP/Yahoo story by Rasha Madkour…and there’s a slide show.)

Reading, Writing, and ’Rithmetic

Yesterday was (depending upon who’s counting) the 16th anniversary of that thing we call the World Wide Web becoming a public entity. The Web is not to be confused with the Internet, which is much older, of course1. I’m talking about Tim Berners-Lee’s idea and implementation thereof. (I should not neglect to mention that this was done at CERN, the particle physics laboratory in Europe.) His original posting (on the newsgroup alt.hypertext) proposing the structure can be viewed here, and here’s an extract:

The project started with the philosophy that much academic information should be freely available to anyone. It aims to allow information sharing within internationally dispersed teams, and the dissemination of information by support groups.

Reader view

The WWW world consists of documents, and links. Indexes are special documents which, rather than being read, may be searched. The result of such a search is another (”virtual”) document containing links to the documents found. A simple protocol (”HTTP”) is used to allow a browser program to request a keyword search by a remote information server.

The web contains documents in many formats. Those documents which are hypertext, (real or virtual) contain links to other documents, or places within documents. All documents, whether real, virtual or indexes, look similar to the reader and are contained within the same addressing scheme.

To follow a link, a reader clicks with a mouse (or types in a number if he or she has no mouse). To search and index, a reader gives keywords (or other search criteria). These are the only operations necessary to access the entire world of data.

What am I going to do to celebrate?

letter to anonSince everyday I celebrate the WWW by using it a lot, to commemorate the event I think I’m going to pay a visit to the (real, physical) library, then read a good old-fashioned book for a while, and then hand-write a letter. I used to write so many letters, long ago, and from time to time I try to stop everything and pick up a pen and write one. I got in the mood the other day while in Aspen, and went and found some letter-writing paper and envelopes, curled up on a sofa, and wrote for a Continue reading ‘Reading, Writing, and ’Rithmetic’

Return to the Nest

Sorry about the silence. Odd thing: As a result of my (I think) growing absent-mindedness, it turned out that my flight was on Sunday night and not on Saturday night (as I thought when I did the previous post), so I suddenly had an unplanned 24 hours on my hands in Aspen.

ground dove nestI decided to spend the extra day lying low getting some work done - various things I thought would get undone on this trip suddenly had another chance to get done! Mostly administrative stuff. It is amazing how much one can get done when there’s a whole extra day suddenly appearing in your schedule, and so that’s what I worked on.

One thing I could have done was reminded you that the Phoenix was due to launch Saturday, and indeed it did! Be sure to check out a post about it on the Bad Astronomer with some links to really nice launch videos. The Phoenix mission plans rather wonderful things when the craft gets to Mars (including making the old reverse-thrust landing maneuver vogue again), as you can learn from their site.

phoenix spacecraftToday, Monday, saw me running errands. Boring things, really. Things you do after being away from the nest for three weeks.

This leads me to the garden report. Nothing to say except that there’s Continue reading ‘Return to the Nest’

The Walk Up Mount Wilson

[A friend of mine in LA told me today that she was planning to go with a group of friends to do some observing up at the big telescope on Mount Wilson. This put me in mind of a post that I did on CV two years ago (how time flies!) about some of the science done up there at the Mount Wilson Observatory, thoughts surrounding, all combined with a hike up to it that I felt compelled to do upon seeing it from the air. I thought I’d bring that old post back for you to read, with enlargeable pictures as a bonus. Enjoy. -cvj]
___________________________________________________________________________________

sign to mount wilsonAs you know from an earlier post, I left Aspen on Friday and headed home. This involves changing planes at Denver, and then flying over the strange, beautiful, and changing landscape West to Los Angeles. It only takes about a couple of hours. I was thinking hard about our discussion about the Greatest Physics Paper! and trying to think of those forgotten examples of great work. The people who’s songs are seldom sung. The unglamourous “bread and butter” works that seldom get written up in the newspapers near the time that they are produced, if ever. These solid works are examples of what every scientist should do as a matter of course: You look at the evidence you have before you, gather more if necessary, make some assumptions, form a hypothesis, and test it against the data. Next, come to a conclusion, and report your results as clearly and honestly as you can, and so on.

Whether or not you have some vision about what it all means does not necessarily qualify or disqualify the resulting paper as a candidate for being a great paper. It can still take its place in the tapestry that is the sum of efforts of generation after generation of physicist to make sense of our world, and find its meaning there.

Mount Wilson Hike -  foliageSo I was thinking about this all, and my mind switched to some recent reading I’d been doing. Simon Singh’s excellent book, “Big Bang” had been on my bedside table recently, and although I’d not had a lot of time to read it, I was curious to dip into it from time to time. This is partly because, while I know several of the stories and the history that he tells, it is always of great value to see how another tells those stories. I always learn something, either in the facts or in the telling.

As we’d been discussing before, Einstein’s papers are modern examples of work that changed our entire view of how the universe that we inhabit is really put together. How can those fail to be top candidates for the best physics papers ever? Same thing for Newton, and for Galileo, etc.

However, it’s easy to forget that for several years after Einstein’s breakthrough with General Relativity [see a later post I did here], the world still thought that the entire universe was just the Milky Way Galaxy. It was not until the year 1923 that Edwin Hubble (in one of his many great contributions) established extremely cleanly that the Andromeda Galaxy was several times further away from the center of the Milky Way than the edge of the Milky Way itself. This was a truly shattering change of perspective Continue reading ‘The Walk Up Mount Wilson’

Showing a Different Way

danica mckellar Getty imagesDanica McKellar (the actress who played Winnie in that show The Wonder Years that many of you might remember) has been working to try to encourage young girls to go more for “Cute and Smart”, as opposed to “Cute and Dumb”. Bottom line: Less Lindsay Lohan, and Paris Hilton, and more…. well, Danica. (I’m sure there are other Tinseltown examples here… can I have some help?).

Danica sets an excellent example of why the two (being considered attractive on the one hand, and smart on the other) are not mutually exclusive, while not suffering from the “geek” or “nerd” label that is attached by the entertainment industry to certain groups of people who enjoy using their brains a lot. She trained as a mathematician, in fact, doing her undergraduate work at UCLA so well that she did rather good published research work (NPR piece here Update: It is actually more of a theoretical physics problem, it appears.). This is from someone who struggled with the subject in sixth grade. Why is she in the news? She’s written a new book “Math Doesn’t Suck”, the aim being to encourage girls to avoid the (social) barriers to getting into mathematics. Excellent title. (I wonder if they’ll change it to “Maths Doesn’t Suck” if they publish it in Britain? “Suck” British kids have adopted from the USA cultural juggernaut, but “Math”? Not yet.)

danica mckellar math doesn't suckActually, looking at her website, I see that the full title appears to be “Math Doesn’t Suck: How to Survive Middle School Math Without Losing Your Mind or Breaking a Nail”, which is more of a mouthful, a bit less zippy, but oh well. It’s all very Clueless, in a good way. Here’s a link to the book’s site, and it is due out tomorrow.

There’s an article1 on her recent Newsweek quote at CNN, from which I grabbed this:

“When girls see the antics of Paris Hilton and Lindsay Lohan, they think that being fun and glamorous also means being dumb and irresponsible,” the 32-year-old McKellar told Newsweek for editions to hit newsstands Monday.

“But I want to show them that being smart is cool,” she said. “Being good at math is cool. And not only that, it can help them get what they want out of life.”

but you should go and read the whole thing, by clicking here. [Update: Better article here by Corey Binns in Good Magazine. Extract:

“The book hones in on middle school’s trickiest points-––like fractions, ratios, and percentages—and presents them in a style that’s appropriate for the cool kids’ lunch table. Figure out your “type” in boys and you’ll understand greatest common factors. All of those iced lattes celebrities drink make multiplying fractions tasty. Plus, savvy shopping requires killer decimal skills.”

Go Danica!
