Some big news:

wired science bannerAs I said in the previous post, there’s more to the new WIRED Science TV show on PBS than just the TV show. The website is going to be full of quite a lot of additional material, starting next Wednesday. There’ll be show episodes, extensions of some of the segments, extra links to expand upon the stories, materials for schools, and so forth. But there’s also something else in the works. There’ll be a dedicated blog for the show, and it is called “Correlations”.

Correlations is a new group science blog, with bloggers of a range of interests. It will be connected to the show in many ways, but will expand well beyond the show into aspects of science and technology of all sorts, according to the tastes of the bloggers involved. There’ll be all sorts of interesting material, from serious stuff to fun stuff, and points in between. I think that it’s a great combination of bloggers (the team was assembled by Leighton Woodhouse, of KCET – we had a great conversation about the whole business of science blogging and science bloggers back during the Summer) and I’m quite excited to see how it goes. Who are they? Well, here’s the list:

WIRED Science

I promised some interesting television news earlier, and here it is. Well, it is actually blogging news too. First let me step back a touch. Recall that some time back I mentioned that there were a number of new science shows vying for the nod from PBS to be their new primetime science show? Viewers could go in and vote on which show they preferred. Well, the show that won this was WIRED Science, the show I also told you more about here. I’m pleased about this since I thought it was actually the best of the bunch.

wired science bannerSo they’ve made some cast changes, and made new episodes (and are in the process of making more). The format is sort of like a magazine, so there are two people based in the studio (Chris Hardwick and Kamala Lopez) who introduce segments that are then played. These segments are essentially field reports from various reporters and agents in the field (Ziya Tong and Adam Rogers are two other principals in the studio at the start, but they are mostly doing field reports). There will also be some studio interviews (Ziya interviews Paul Kedrosky in the first show), and some other studio segments, like “What’s Inside” by Chris Hardwick, where he goes through a description of what’s inside an everyday household object or material. (I hope they do more of those – he’s really good at that.) For those of you from the UK, you’ll recognize the format – it is essentially like Tomorrow’s World used to be, but with more science1 (although since this is a WIRED project too, there’s going to be the fun/cool toys aspect).

The show’s headliners: Chris, Ziya, Adam and Kamala

The first one airs next week, on Wednesday October 3rd at 8:00pm. There’s a page here you can go to in order to have a look at the cast, and also see some clips from […] Click to continue reading this post →

Magnetic Vision?

garden warbler by Tommy Holden. British Trust for Ornithology websiteThis is simply fascinating. I heard about it on NPR. While it is well known that birds are sensitive to the earth’s magnetic field, and use it to navigate, apparently it’s only been recently shown that this sensitivity is connected directly to the visual system (at least in some birds). The idea seems to be that the bird has evolved a mechanism for essentially seeing the magnetic field, presumably in the sense that magnetic information is encoded in the visual field and mapped to the brain along with the usual visual data. (Image: A garden warbler, photographed by Tommy Holden. I found it on the British Trust for Ornithology website, here.)

Dawn at Dawn

Well, it is time for Round Two!

dawn spacecraft getting readyRecall that (as mentioned in my post with the doom-laden title) the Dawn mission was postponed by several months due to unfavourable launch conditions. Recall also that the celestial window for launching Dawn will not come again for another seventeen years, if it does not launch over the next couple of weeks or so! This is a bit scary therefore.

So the two week launch window is open, and Dawn is on the pad and ready to try to fly tomorrow, at around….. dawn. They’ve been preparing Dawn for this for a while now (you can see in the picture on the right some of the preparations – encasing it in the protective dressing for the rocket launch… I got this picture from this link and you can see more there), and from the press release of yesterday confirming that the mission is a “go”:

dawn spacecraft rendition“If you live in the Bahamas this is one time you can tell your neighbor, with a straight face, that Dawn will rise in the west,” said Dawn Project Manager Keyur Patel of NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “Weather permitting, we are go for launch Thursday morning – a little after dawn.”

Dawn’s Sept. 27 launch window is 7:20 to 7:49 a.m. Eastern Daylight Time (4:20 to 4:49 a.m. Pacific Daylight Time). At the moment of liftoff, the Delta II’s first-stage main engine along with six of its nine solid-fuel boosters will ….

MacArthur Mashup

The MacArthur Fellowships were announced today. These are particularly great, as it’s awarded across so many different fields, and I always learn about interesting work going on by reading the synopses at the website. Congratulations to all recipients!! Before I point to the list, I’d like to make a plea that will, of course, go unheeded.

Please please, people of the media, stop calling them “genius grants”. Just stop. By way of explanation, I can’t quite put my finger on it, but the term just seems to strike the wrong tone about what these things should be about. It seems to me to push the recipients away as being “other” rather than encouraging us all to embrace the qualities that they are being encouraged to show by getting the fellowships. Ok, that’s the end of my plea.

Here’s a reminder of what the Fellowship is about (extract from their site): […] Click to continue reading this post →

Tips on Global Warming

global warming book by Laurie David and Cambria Gordon This looks/sounds like fun.

I heard about it on NPR (audio about it here). I suspect that it will be useful and informative not just for kids, but for us older ones as well. It is by Laurie David and Cambria Gordon. I’ve not read it, but from what I gather from the interview, it is certainly worth a look if you’re in the market for accessible information that someone you know (or a whole household) might like to have.

ScienceWoman’s New Digs

Comments Off on ScienceWoman’s New Digs

Just thought I’d let you know that the blog of ScienceWoman (that I talked about in an earlier post) has now moved. Her blogging about her day to day experiences and thoughts as an early career woman scientist will be getting a whole lot more attention now that it is under the ScienceBlogs umbrella. Go and have a look at her new digs. She’s already started off nicely with a post asking readers to name their favourite woman scientist, with the resulting interesting contributions and discussions you’d expect in the comments. Go and add your two cents.

While I was over at ScienceBlogs (haven’t been in a long while) I spotted a rather […] Click to continue reading this post →

Tales From The Industry, XII – A Shooting Diary

By | | , , , , , , , ,

Here’s my promised report/diary on yesterday’s adventures in film-making.

history channel shoot september6:45am Got up a bit earlier than perhaps I should have, given that I got to sleep at 1:00am. Spent a while reading a ton of email, and sending some more. Will be away from my regular professoring duties for the whole day, and so wanted to make sure the fort was held. Prepared some appropriate TV clothing (pretty much what I wear normally anyway – simple solid colours), and so forth. Attempted to beautify myself just a tad (with the usual…inconclusive results). Shower and so forth. Coffee and oatmeal, sprinkled with NPR… Read a bit of stuff on dates of historical background on material I’ll be talking about. I often forget that sort of thing, and its never ever needed whenever I do remind myself of it, so after a few minutes I decided not to bother. The core physics ideas are more important, ultimately. Spent time looking for rain gear (the micro-brolly, basically), since supposedly there’s going to be a rainstorm later (hurrah! finally!). Ready to go.

8:45am Fifteen minutes later than I intended to (how did that happen?), I set off to walk to the Sunset/Vermont Red Line subway station. Waved to a neighbour, and we exchanged pleasantries about how nice a day it was.

8:47am Walked past surprised neighbour back toward home…. briskly.

8:52am Riding the Brompton (the folding bike, for those of you not keeping up), I cycled off to the Sunset/Vermont station.

9:01am Arrive at said station on schedule (one minute late does not count in LA), and […] Click to continue reading this post →

Whither String Theory? – Too Soon To Tell

By | | , , ,
160 Comments

stringscape image from physics worldGosh, a thoughtfully-written general level (more or less) article on some of the general outcomes of string theory research! It’s written by Matthew Chalmers, and is in the Sept. ’07 edition of Physics World*. The article can be read online here, and downloadable pdf is here. The graphic on the right came with the article. I don’t fully understand what it is, but the title, like that of the article, is “stringscape”… Look, let’s not over-think this cvj – it’s a pretty decoration.

I’ve done a quick read of it (should re-read more carefully later on – it will no doubt have some emphases with which I disagree somewhat**) and I’d say it is very much worth reading. While not a perfect summary (what is?), compared to a lot that’s been out there, you’ll find it rather more informed, less sensational, (refreshingly unpoisoned by various prejudices, such as the presentations of Smolin and Woit – see numerous earlier discussions in the “More Scenes from the Storm in a Teacup” series of posts, and others), and unafraid to go to some length to unpack the issues somewhat carefully.

Very importantly, it contains numerous quotes from various respected researchers in […] Click to continue reading this post →

Home School

By | | , , , , ,

simpsons schoolThis is very interesting to me. I just heard a story (by Nancy Mullane) on NPR’s Weekend Edition about home schooling. (The link is here, and audio will be available at that page shortly). It focuses on the issue that African Americans are the fastest growing group of adopters among minorities in the US. I was also not aware that homeschooling is on a rapid rise.

This raises all sorts of questions for me. Very basic ones. How well does homeschooling work? Does the “product” – an educated person – perform well afterwards, once they’ve rejoined educational settings with the more traditional social environments (colleges and universities). Does the reduced level of social interaction during those homeschooling years have an adverse effect, or is it compensated for by social interaction that presumably takes place after school? Perhaps there are arguments that the reduction in social interaction even helps in some ways? I really don’t know much about this. Do you? I presume there’s all sorts of statistics on this, but I’d be curious to hear a bit of anecdotal discussion in the comments. Perhaps you were homeschooled? Have friends who were? Are homeschooling someone now? Are being homeschooled now? Tell us what you think!

I wonder about this since I’m curious as to whether this results in a different (better, […] Click to continue reading this post →

I’ve Got Next

Ok. So I want to make this post timely, but it means that it will begin to let a cat out of the bag. We’ll see how much I can save for a later post as I write1.

So, as I walked to the subway this morning (yes, they have one in LA), I went through my little checklist of things I take on self-assigned assignments of this sort.

Notebook for scribbling: Check
Pen for scribbling: Check
Camera: Check
Phone (now with decent back-up camera): Check
Spare battery for camera: Check
Decent excuse/reason for being spectacularly late: Check
Water: Check
Good footwear for endless walking back and forth: Check

By now you get it. I’m either doing one of my parade reports, or perhaps a street fair/party, museum exhibit, or some random science fair, object or installation or other. Yes, but which? Well, apparently I was going to the future:

From the Earth to the Moon

Well, I’m reporting on this as part of a longer blog post about an event I attended today at the Los Angeles Convention Center, but since it’ll take me a while to finish, and it will be buried in all the other stuff (including pictures and so forth), I’ll snip out a bit of what I’m saying there to inform you of this interesting development:

google lunar x-prize posterSo what were some of the big ticket items, at least in terms of where all the regular press were? Well, the biggest was of course the X-prize. There was a long movie with lots of stuff about space, and dreams about our future in space, and animations and things of roving robots on planetary surfaces, and all that good stuff…. very nice, I thought, and began to wander off…. and then there was a round of applause from everyone and I came back as a voice announced “The Google Lunar X-Prize”, and various other people showed up on the stage (like one of the founders of Google – forgot his name, and later, good ol’ Buzz Aldrin, who seems to be required at these sorts of events). The Google co-founder guy began his speech by acknowledging all the Google engineers… and announcing that they’d just launched a new version of the moon. Applause. (I’m pretty sure that they mean Google Moon, by the way.)
