Amy Mainzer has shared and discussed the first released picture from the WISE project that was launched (you’ll recall) not so long ago. It looks marvellous. Press release here.
By the way, I hope you’re following Amy’s blog to learn more about the mission now it is in full swing. She’s giving you a window into the science as it breaks and the excitement of doing the science itself, seeing a project come together Click to continue reading this post
Yes, I know: (1) Large head doesn’t make one smarter, but it was just so I could use the post title. (Maybe one or two of you see where it comes from…) (2) The final resort of a busy blogger: – cute animal pictures. Well, I already regularly share pictures with you concerning what I had for dinner, so no change there.

I just thought you’d like to know this. I’m a Specialty Act. Got that?
Last month, just before taping some material for a new TV show (that you can see on a major broadcast network starting in a week or so) I signed some routine documents. One of them involved me ticking a box to specify my official status for Click to continue reading this post
Happy New Year, dear Reader!
Forgive me for starting the year with an article on environmental problems, but it was Isaac Asimov’s birthday (at least the official one) on Saturday (I learned that here), and I found an excellent video of him talking wonderfully about global warming, united world action on such matters, and other issues back in 1988. It is below. I read a ton of Asimov back when I was a teenager. While not the greatest writing in a literary sense, it was full of wonderful ideas and compelling stories, and was quite inspiring for me at the time.
It is a pity that it was yesterday I switched on the little robot I use weekly to help me fight the good fight against dusty floors (see above right; the company that makes them is called iRobot, by the way – hardly any doubt that an Asimov reader was Click to continue reading this post

It has been rather pleasant here in Los Angeles over the last week or two, since there has been a mixture of rain, cloud, and sunshine that has been very good for all concerned: climate, mood, garden, etc.
Perhaps you’ll have noticed that I’ve been quiet with regards writing here over the holiday period. This is not because I’ve fallen off the planet or anything! I’ve been Click to continue reading this post

Happy Holidays, one and all!

I noticed yesterday that there’s a new group blog, at NPR, on science and culture, and – to my pleasant surprise – one of the co-authors is my friend and colleague KC Cole, the well known (and quite marvellous) science writer! I’ve met the physicist Marcelo Gleiser who will be a co-author and he seems like an excellent new voice to hear from. Astrophysicist Adam Frank and Biologists Ursula Goodenough and Stuart Kauffman round out the exciting-looking roster. (I cheekily grabbed a screen shot of the roster photos (left) from their site.) There are a number of lovely pieces up on the site already for you to read.
The blog is called 13.7, a number that might be familiar to you.
No? You might be thinking that it is the new high price for a basic over-priced cup of “gourmet” coffee in some new tediously pretentious cafe in LA (and believe me, I’d not be at all surprised), but I was in fact referring to the 13.7 billion years that is the age of our universe. I think that is the primary meaning they had in mind too. I’m pleased to see these new voices in the blogosphere, and pleased that authors of blogs of this sort can still come up with excellent names! 13.7 is a really rather nice name and, in a slightly inside way, captures the scope, variety, and grandeur of the themes I expect they’ll explore in much the same way that the name Cosmic Variance promised (and delivered) for that group blog back in 2005. I came up with that name a little before we launched the blog (we mulled Click to continue reading this post
Sometimes I find the most elaborate ways of procrastinating when faced with a tedious task (this time, gathering all my grade data for my class together and doing the analysis to produce a final letter grade):
It is good when the distraction produces good and useful results, of course, and a Click to continue reading this post
They’re sitting the final exam for my graduate electromagnetism class right now, having started at the ungodly hour of 8:00am. I’m sitting outside in the bright, lukewarm Winter sun with a cup of coffee, two cheesy biscuits I baked at 6:30am for no reason other than feeling in a baking mood (see right), my phone in case there’s a reason for the TA on duty to contact me, and my iPod, which I am of course using to write to you.
It has been an odd few days. Not so much because of the pair of them that had me wandering around a huge studio lot, being wardrobe-checked and make-up checked, shot from all angles with a live cheering studio audience in attendance (for your viewing pleasure on a new prime-time series on Fox to begin airing next month – more on this later, perhaps), but because early on Saturday I woke up with a severe vertigo attack. 
Very odd indeed and although I managed to get it under control and it had worn off over the days, every now and again it gets close to being triggered again. I don’t know the source for sure – I think it was correlated with a reaction to some of the food I had on set, maybe combined somehow with the severe ear blockage I had about a month ago after catching a (short-lived) cold on a long transatlantic flight? – but I have to say (and this is the point of my digression here) that it is a remarkably odd experience for me to feel slightly off balance for such an extended period. I’m used to being on the tips of my toes ready to skitter along the line at the edge of a low wall if the mood takes me while walking along. But I can’t imagine doing that now. I feel like I’ve lost my powers… it’s often amazing to me how little it takes to make a person feel very mortal, even fragile, again. It will no doubt pass.
I’ve been gentle on this final exam. I still find it disturbing that kids today (yes, I said “kids today” – perhaps my lack of equilibrium has put me in crotchety-old-man mode), even the very smart ones, typically do badly on any advanced exam that Click to continue reading this post
My friend, The Universe co-contributor, and colleague Amy Mainzer (JPL) is rubbing gloved hands together in the chilly night air up at Vandenberg. Well, ok, if not this very moment, she probably will be at various points this evening and into the wee hours of the morning. The launch pad for WISE (the mission on which Amy is deputy project scientist) is set, and everything is ready to go! See my earlier post about what Click to continue reading this post
The skies have cleared here in Los Angeles after a sequence of remarkably rainy days – really torrential downpours that have been very enjoyable. Happily, the clearing has taken place just in time to see the Geminid meteors, which I learned are likely to be quite striking this year*. After midnight or so ought to be good for viewing, and be sure to be looking at the right part of the sky (they originate from the direction of Gemini – see the NASA map on the right). There’s more about it on NASA’s site, and be sure to look at their tips for viewing.

There’s a physics angle to the Tiger Woods business of last week (that I’d not really been following since I was, thankfully, out of the country during the media blitz).
A physics angle? Really? Surely in my attempts to show the science angle in everyday things I’ve gone too far?
Well, actually there is. So there was some business with a car crashing and so forth, and there are photos of the interior of the car. There’s a book visible. It’s a physics book! It is John Gribbins’ Get a Grip on Physics, from 1999. 
It is out of print now, but apparently its Amazon (USA) sales rank shot from 396,224 to 2,268 over a short period. (For the record, before you ask about the other items in the photos (from Getty images), I’ve heard no news on whether umbrella sales also spiked. Or bottled water sales, for that matter.)
I like this story for lots of reasons, but the main one is that this shows to the Click to continue reading this post
When I’ve got a decent amount of jetlag, coming West, I find it not so much of a drawback as a way of seeing how to arrange one’s days differently. Sometimes the results are tasty. I had to leave a birthday party early last night due to the need to sleep, but this meant that at 6:00am today I suddenly felt in the mood to make a walnut Click to continue reading this post
No doubt you’ve been aware of the recent debate that has been raging about whether or not the scientific case for climate change has been exaggerated by various scientists, in the light of the content of a long series of emails. It’s all over the news, and so I am sure I don’t need to point to all the news stories, commentaries, and – sad to say – convenient distractions that have been constructed on the basis of them by the climate change deniers, especially those with vested interest in the status quo. (Follow the climategate tag at The Intersection for some of the links, and a sampling of the discussions, and do look at the Nature editorial for example.) This matter, and the debates it has reignited, is of course a major issue in view of the upcoming work to be done by the leaders of the world’s major economies in Copenhagen later this month.
A key point here is to realize that when science intersects with politics – especially the kind of rabid, personal, dirty politics that surrounds the climate change issue – the grey areas that are already present in honest science can get further muddied by the fact that scientists are human beings who don’t always act perfectly in all situations, and whose actions (well emails suggesting certain actions) can also be subject to question (especially when we don’t have all the facts concerning context, etc, on several of the emails which seem very ambiguous to me).
There are two things to keep in mind. The first is that there is a global community of scientists at work here, with so many different approaches, motivations, contexts, data sets, and so forth that have been brought to bear on the matter of climate science. To think that a series of emails from some small subset of them (that may or may not suggest that data have been presented unevenly, for whatever reasons) can undermine a huge body of work and conclusions from an entire worldwide scientific community is to seriously misunderstand what science is about, and how it works. 
It is not a tall, tottering late-stage game of jenga, where there’s a danger that at any moment one of the little wooden sticks will wobble and bring the whole game crashing to the ground. Instead, it is a highly interwoven collection of findings, ideas, analysis, and conclusions that are supported by a wide variety of pieces of evidence, all arriving at the same striking picture – Our world is changing fast and our actions are highly relevant to these changes both past, present and future. Instead of a jenga construction, think more of a woven tapestry. Pulling out a few threads changes it a little bit, but it does not make the whole thing unravel and destroy the picture. Or, if you like, think of a pyramid structure, like the lovely Pyramid of the Sun at Teotihuacán in Mexico (image borrowed from here). Click to continue reading this post
Yes, I sometimes find myself asking the question “Is it just me or…?” from time to time. Something to do with the issue of differing views of the world and so forth… This time it is about this bag.
To me, there’s a huge Pi on it, first and foremost. Just Pi. You know, the ratio of a circle’s circumference to its diameter. When I first saw it I had not seen the octopus written below, and so was feeling pleased to see a commercial logo on a shopping bag that simply had Pi on it. It fit with my oft-expressed desire to see more science and science related things out there in the general culture. This stretched to plays on numbers, mathematics, and so forth.
So then I wondered what the Pi stood for, or what clever pun they were going to work into the mix to connect it to their product. Then I saw that they simply meant it to be octopus eyes. (On a severely deformed octopus – I always thought that they had eight legs…). Given that the blob has the wrong number of legs and all, I can’t properly make it work for me as an octopus. How about you?
Bit disappointing that Pi is not involved. Perhaps it could have worked if the store was using the plural form of the animal’s name.
I’ve been saying legs. Perhaps I should say “appendages”. This all puts me in mind of Click to continue reading this post
