Yes, it’s very funny*, and awfully close to the truth as well, at least in terms of the final product. More seriously, it is worth noting that what they get wrong is the blaming of it on audiences. It is actually more about the channels (not just the Science Channel) themselves and the sort of business models they run. We, the scientists who care to, must carry on contributing where we can as well as encouraging and supporting the film-makers as much as we can. It’s not really their fault so much as the people who call the shots at the head of the money food chain. Most of the film-makers I’ve worked with on the many shows I’ve helped with (either in front of or behind the camera, or both) are passionate about the science, are keenly interested in understanding it more so as to tell the story to the public as well as they can, and are capable of doing so. They most often can’t get their shows past the people at the top who believe that the material is too inaccessible or not interesting to the public. (I’ve heard the same complaint from science journalists working in the print media too.) On the other hand, I get recognized and stopped on Continue reading ‘The Onion on Science Programming’

(Well, in the Ion Micrograph category, you understand.)

Sometimes extreme geekery is charming. (As you may know, I do not use the word “geek” lightly.) I spotted this on Phil’s Bad Astronomy Blog. You know what shape it is trying to evoke, I presume. Know also that this structure is 8.8 micro meters across, and that the subject was magnified some 5000 times normal size to make the image. I’ve no idea how they Continue reading ‘Best in Show’

These are not really my cup of tea (at least not first choice), so to speak, but they are very pretty.

While working at the countertop of a coffee bar at Mercado San Miguel, in Madrid, (drinking my usual café cortado) I watched the fellow at the counter making them for some customers.

It was a rather elaborate process, and quite fascinating to watch. It might seem odd Continue reading ‘Dessert Coffees’

I received an email the other day asking me if I had any connection to the new initiative announced at USC recently (link here), talking about a new partnership (involving USC and the NSF) for increasing and improving the amount of science in entertainment and media products such as films and television shows, and probably more. It is called the Creative Science Studio, or CS2. You’ve read me talk about these sorts of projects on the blog a huge amount, and so I won’t repeat the motivations here (you can find earlier thoughts if you look under some of the categories this post is in for other posts on the subject).

One of the fallouts (fallsout?) of being a dabbler, behind-the-scenes-agitator and general troublemaker is that one can never really tell what are all the final projects, initiatives (and so forth) that come about as a result (at least in part) of one’s actions. In trying to significantly move forward things such as this (involving public Continue reading ‘The Creative Science Studio’

Phil over at Bad Astronomy has posted about my childhood cradle (although I am sure he does not know that), the (still beautiful) island of Montserrat. I grew up there for ten years from ages 4 to 14. Many years later, in 1997, a volcano erupted there (in the “Soufrière Hills”) and devastated much of the Southern part (where I grew up) of the island wiping out almost all traces of where I lived. Much of the stuff of my childhood memories is buried under tens of feet of ash. In my more tender moments, this thought still brings me to tears, actually. (Yes, of course I do know that it is much more devastating for those whose lives it affects due to their living there in the present.) On a side note, I always find it slightly chilling that the mountain that erupted was one of a pair that I used to love to sit on a giant rock and stare at, for long periods, when I was in a contemplative mood (as I often was) when I was young. Furthermore, two weeks before the eruption I was actually visiting the island for the first time since I’d left it as a child. And guess what I did? One day I was in a foul mood over an issue, and I went and sat on that rock again and while brooding, looked over at the mountain for a long spell. (Just in case, I try not to get too angry these days… )

It turns out that the volcano has continued to rumble and burp over all these years, sometimes dangerously, with a growing dome that forms on top of the whole Continue reading ‘Collapse Results From Space’

A little while ago, this season’s edition of the USC College magazine came out, and it is available online. Notably, it is featuring writers and writing, and there are several pieces in there about both faculty and students and their writing, in various forms. There are articles about superstars such as TC Boyle and Aimee Bender, as well as pieces by excellent writers such as California Poet Laureate Carol Muske-Dukes, and M. G. Lord. I recommend having a read of it.

It is with a mixture of mild amusement and embarrassment that I mention that among all that excellent writerly material is, perhaps oddly, an article on yours truly. It is about this blog, what it is about and for, and why I do it. (The blog is, of course, not to be mistaken for great writing, and so I will apologize personally to Aimee Continue reading ‘The Write Stuff’

Here is a list of fifty videos with a space theme that might be worth bookmarking and coming back to during the quiet moments. Forget the “top 50″ business - I’ve no idea how the X-Ray Vision-aries arrived at this particular list or order - it is just another collection. There’s some really good stuff on it, and that’s all that matters, in the long run.

Share!

Speaking of videos. Have you seen my films yet? Even if you have, it’s always fun to look again. See here and here.

I’d been inside all day, working while listening to the rain and the occasional clap of thunder. They are rare here and so I’ve been making sure to thoroughly enjoy the parade of storms we’ve been having over the last several weeks.

Today (Tuesday 9th!) was definitely a day I’d planned to stay in, rain or not, since I wanted to dig further into a project I’m working on, and focus on it all day. And so focus I did, until late in the afternoon I noticed a lovely light on the buildings and trees, telling me that the sun had emerged from the clouds just before it dropped below the horizon - peeking through that gap between the clouds and the sea that, now I think of it, must always exist quite clearly if there is a localized set of clouds over the region, due to the storm. I thought I’d go outside for the first time of the day and look at this evening light, and I noticed it was still raining and there was a rainbow! Actually, it turned out to be two. A double treat stretching majestically across the sky. I grabbed a piece for you. [Update: Several pieces. Glued two together for you to get the full effect. See above. It was raining, so was not so careful with my alignments when snapping in my haste to escape....]

Notice that the colour sequence (ROYGBIV) runs backwards on one as compared to the other. Continue reading ‘Double Treat’

So yes, the Categorically Not! series was a bit thin on the ground in the last several months. I think KC was a bit busy travelling to tell people about her Frank Oppenheimer book.

Well, it is back on the calendar, and I probably should have mentioned it earlier, but the next one is tomorrow, so I thought I’d remind you. Remember that the series of events is held at the Santa Monica Art Studios, (with occasional exceptions). It’s a series - started and run by science writer K. C. Cole - of fun and informative conversations deliberately ignoring the traditional boundaries between art, science, humanities, and other subjects. I strongly encourage you to come to them if you’re in the area. Here is the website that describes past ones, and upcoming ones. See also the links at the end of the post for some announcements and descriptions (and even video) of previous events.

The theme this month is Grand Challenges!. Here’s the description from K. C. Cole:

Today I’ve got to give a guest lecture in a class of KC Cole’s at USC’s Annenberg School. I’m supposed to talk on the theme of Art and Science. I’ll cover a number of aspects, I expect (have not written it yet), but it put me in mind of two posts I did a while back on the subject. One was over at Correlations (remember that?) and the other, called Transcendence, was here. I thought I’d reproduce some of the Correlations post, called Essence, here. The back story was that I was working up a contribution to SEED magazine (the December 2007 issue I think) which was doing a cover story on Science and Art, and… well, I’ll let the 2007 me tell you the rest:

While working on the contribution, I was hugely conflicted, for many reasons (variety of themes, variety of pieces, art forms, only 100 words, etc…) and another major theme struggled for dominance - “essence”. How both science and art strive to identify the essential truth about a subject. My original contribution that I submitted to the editors to get their feedback on whether I was on the right track for what they were looking for therefore had a bit more of this in it, and referred to two pieces of art (I eventually chose one and focussed on developing and rewriting around that, using the “transcendence” theme). The piece I used that did I did not use for the final article is perfect for illustrating the “essence” theme, and so to provoke some thoughts in you [...] I include it here, along with some fragments of the paragraphs I was playing with at the time:

Continue reading ‘Essence’

This story has come along at just the right time, given that my last post was about Einstein. Seems that Niels Bohr (another giant from the same period, and another one of the founders of the quantum theory) was a big fan of cowboy movies, and thought a lot about gunfights. Yes, really! (There he is in the photo on the left hanging out with his friend Einstein in later years, perhaps 1925. Perhaps they’re at a drive-in movie? I got this photo here.)

It turns out to be all relevant to new studies about reaction time. The fastest person to draw does not necessarily win the gunfight:

So I was chatting with a friend of mine the other day about science and scientists, and in particular what on earth we theoretical physicists actually do.

She (mostly jokingly I think) said we’re really all a bit weird, just sitting around thinking about quantum physics all day. I tried to begin to explain that we don’t sit around thinking about quantum mechanics all day any more than a tailor sits around all day thinking about needles. (Or how many angels or demons can fly through the eyes of said needles at the same time.) No, we’re mostly getting on with using the needles in the making of new suits and so forth. (To continue the allegory.)

But I did not get to that analogy, because another thing came up. She went on to say “…like Einstein, with crazy hair…”, to invoke her primary example of the crazy quantum scientist. Now, given that she was talking to me (er… no crazy hair, in case you are wondering), she was clearly joking, but in my view, at the core of all that is a serious image problem that science has to deal with - bizarre clichés about who we are and what we look like. So I thought I’d point something out.

The most famous image of the crazy/eccentric scientist is largely based on a lie (or Continue reading ‘Crazy Al’

Terry Gross interviewed Scott Patterson and Ed Thorp on NPR’s Fresh Air. I heard it yesterday. It was very interesting to listen to Thorp in particular, a mathematician, describing his curiosity about how to construct a system for beating various gambling games, and going from there to the stock market, in effect becoming one of the earliest of the “quants”,

Thorp and the people who use such systems have come to be known as “quants” — it’s a reference to the quantitative-analysis techniques they employ — and their stories are told in Scott Patterson’s new book The Quants: How a New Breed of Math Whizzes Conquered Wall Street and Nearly Destroyed It.

You can hear the interview here, and read an extract from the book. Very interesting are the questions about what they think really went wrong in the market crash of Continue reading ‘Mathematics in Your Business’

This is a fun poster I saw at the Grove the other day. (Click for a larger view.)

The good fairy (Tinkerbell, apparently) speaks the truth!

It’s nice to see such a campaign, and aimed at the younger set (who in turn might bug their parents into thinking about it too). It is sponsored by the Department of Energy (the same people who sponsor most of my research), and you can look at the website here. Maybe you’ll direct some others to it too! There’s an energy action checklist, and lots of useful tips and guidelines for everyone (young and old) to follow in order Continue reading ‘You Don’t Need Magic To Use Energy Wisely’

Did you watch Meteorite Men last week? If not, you can probably catch a repeat. It is a new series, airing 9pm ET/PT Wednesday nights, on the Science Channel about two guys who search for meteorites. Check your local listings for times. (Photo cheekily snapped from their site. Copyright aerolite meteorites.)

I learned about it from Bob Melisso, my producer/filmmaker friend (and occasional collaborator: see here, here and here) who made the pilot and is the supervising producer for the series. From the website:

“If you want your children to be intelligent, read them fairy tales. If you want them to be more intelligent, read them more fairy tales.”

Do you know who said that? I’ll break the post here to give you a moment to think about it. I’m not going to ask for the answer in the comments since you have Google on your side, but you can, if you like, share in the comments whether you knew or guessed it right before you moved to the rest of the post below to learn the answer. (Image above is an illustration by Walter Crane for ‘Snow White’ (1882).) Continuing…

…more to go. I’ve finished one of the papers I’ve been writing (this one co-authored with my student, Tameem) after delaying on it for months. I’m not sure how things got quite this backed up in terms of things I have to do, but they have. I meant to start on a new, long project last week, and all my efforts these days have been toward clearing away all those things I want to get done and dusted before focusing on that. It is taking time, but gradually the clearing is happening. Two more manuscripts to complete.

This paper reports on the continuation of the work we’ve been doing over the years in understanding the physics of various model systems in an applied magnetic field. This is in the context of holographic models of important strongly coupled phenomena that are of considerable interest in lots of fields of physics (particle physics, nuclear physics, condensed matter physics, atomic physics). (Since I don’t want to explain holography and so forth every time I talk about it, see a post I did about some of that here, and related posts in the list at the bottom of this one, if not sure what I’m talking about.) (Hmmmm, I see from my SPIRES listing that I’ve got seven papers mentioning magnetic field explicitly in the title in the last three years, and three or four more of the rest are occupied in large part with the issue too. No, really, I’m not obsessed.)

The issue here is the study of structures that suggest themselves as earmarks of Fermi surfaces in strongly coupled systems. It has been a goal for a long time in the context of gauge/gravity duals to understand what the signals of a Fermi surface would be. Would it be some geometrical object in the dual gravity theory, perhaps? Access to a computationally tractable description of such an object would be rather Continue reading ‘News From The Front, VIII: One Down…’

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 Continue reading ‘Eye on the Sky’

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 Continue reading ‘Tales from the Industry XXX - Specialty Act’

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 Continue reading ‘Amazing Asimov’

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 Continue reading ‘New Voices, Great Name’

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 Continue reading ‘Final Morsels’

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 Continue reading ‘Imminent Launch’

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.

Don’t forget: - don’t assume that being in a large city means you can’t see anything Continue reading ‘Geminids!’

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 Continue reading ‘A Gripping Read’

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). Continue reading ‘On Science and Politics’

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 Continue reading ‘OctoTriple’

It was Darwin’s birthday earlier this week, with lots of celebrations of the man and his work going on in many places (in addition to the year-long celebrations for Darwin year). On the other hand, there was at least one events last week that were rather sad and definitely not cause for celebration. You may have heard that evangelist Ray Comfort decided to launch an anti-science campaign on 100 university campuses by distributing copies of Darwin’s Origin of Species with a 54 page introduction written by Comfort which is basically a poorly written misleading piece of nonsense.

The day after this happened (I’d forgotten all about it as I am on a mission in Europe right now) I got an email from a USC student, Arvind Iyer, who was not only concerned about the content of what was being given out, but the very idea that such access could be given to the Comfort group. He wrote a letter to the campus newspaper, the Daily Trojan, about this, but they chose not to take up the issue at all. I’ll reprint it (with Arvind’s permission) and the end of this, and you are free to discuss with him in the comments what you think of his thoughts.

The issue of access (and freedom of speech, etc) aside for a moment, there is the issue of what kind of response is worthwhile. Most people just ignore the issue, saying that it does not matter, or that we should “live and let live”, etc., and in an ideal world where our society has a better grasp of basic science education, and where science and religion are not so tangled up in so many political discussions, I’d have agreed, but we do not live in that world. As a result, there needs to be some Continue reading ‘DisComfort’

I got these two items about lists of 50 things within 8 hours of each other. They don’t seem connected, so I think it is a coincidence of some kind. Interesting…

(1) The e-Health news blog has published a list of 50 websites under the heading “Top 50 Free Open Courseware Classes for Aspiring Scientists”. It includes sites with open access course materials.

(2) The site Accredited Colleges Online (.org) has compiled a list they call “50 Best Physics Blogs”. Our* little effort, Asymptotia (which I think of as a blog that happens to be Continue reading ‘Twice 50 Science Online Destinations’

Once again I’m excited about a new piece of machinery. This time it is a space mission again. There have been several remarkable missions launched (many in very recent years), doing all sorts of excellent science, helping us discover all sorts of things about our universe, near and far, young and old. I’ve spoken about (and sometimes followed live) the launches of some of them here on the blog, or spoken about the science results they’ve helped produce. See the graphic on the right for some of them.

Well, very soon (possibly as early as December 9th), there will be the launch of WISE, the Wide-field Infrared Survey Explorer! I learned from my friend, colleague and fellow presenter on History Channel’s The Universe, JPL’s Amy Mainzer, who is a senior scientist and the deputy project scientist on the WISE mission, that they made a series of exciting videos about WISE for you to learn about the science that WISE will do and how it will go about Continue reading ‘Get Wise to WISE’

Ah yes. I’ll admit it: Except for the moustache and a few other details, the scene is eerily familiar… (The embed for the video is below.)

Does anyone know who originally started this brilliant series? For those who don’t know it is a 4 minute clip from the 2004 film Der Undergang that several people have periodically re-subtitled with words that have Hitler reacting to an event of some sort. (Warning: Many of them are full of language some might find a bit strong, so watch out!!)

Here it is*:

Well, I’m simply exhausted. I gave my second two-hour lecture today and drained my energy resources quite a bit. This is after an early(ish) start to the morning (7:30am) and with going late to bed last night (1:30am). A good lunch afterward helped restore things to a balance a bit, but I need to rest some more.

I’ve been modifying my lectures during the process of giving them, making adjustments for time and the kind of questions I get. This means that I end up kicking some parts to later lectures, and then trying to spend some of the afternoon writing new material, as well as on the train back to my hotel, and in the evenings.

Well, briefly in the evenings so far. That is because last night was set aside for a tour of some of the tapas you can find in the old part of Madrid. I had the presence of mind to go back to my hotel and get a short nap first, and then met my gracious Continue reading ‘Working and Playing Hard’

Well, a very gentle sort of wham. Yesterday the Large Hadron Collider at CERN had its first collisions of protons! It is a warm start, making sure everything is working before ramping up the energies to regimes where we hope to see new physics, but it is a very exciting milestone nonetheless*. Recall that a few days back they hit the landmark of getting the machine to circulate beams again for the first time. (If you’ve forgotten what all of this is for, please search the blog for “LHC” and/or look in the related posts list at the bottom of this one.) Above right is a visual reconstruction of some of the collision data seen at the ALICE detector, and you can see more of this sort of data at CERN’s website (from where I got this graphic).

From the press release:

It was in the news today, I’m told*. The LHC is circulating beams again!! This is exciting news indeed. Look out for a press conference on Monday, and here is a press release about the event that took place yesterday. Also, collisions are said to be going to happen next week! This is all very wonderful.

I’m mid-travel, and should be sleeping for an early start tomorrow, and so I’ll simply point over to Continue reading ‘Coming Around the Bend Again’

Well, it has been quite the week so far. I’ve been mostly in England. First I spent Tuesday getting over the main effects of jetlag and a short but strong cold (both more or less gone now), and then Wednesday I went to King’s College London to give a seminar to the three groups in the Triangle series of seminars - King’s, Imperial, Queen Mary are the three places the participating research groups in theoretical high energy physics come from. It was excellent to see so many old friends and colleagues, meet some new ones, and chat physics at the pub and over dinner later on. The seminar seemed to be well received, although I know I was far from my best, given jetlag and cold. The next two days saw me saying hi to family and friends at coffee and dinner in the evenings and visiting at Queen Mary and Imperial for the day, and hiding in the British Library for most of Friday, writing.

What am I writing? Four lectures on D-branes and string theory and M-theory, with a focus on some of the fun and instructive applications (and potential applications) of Continue reading ‘Here, There, and Everywhere’

I had a lot of time to kill in Philadelphia’s International Airport on Sunday (I was changing planes), and I must say that is not a bad airport in which to be in such a situation. I like the city a lot, and so am not surprised that its main airport is to my liking. First of all, who can not like an airport that supplies you with… (you’re expecting free wireless, and they had that, sure, but no, I mean)… with… Rocking Chairs!!!

I saw some excellent art as well. And lots of displays of various types. I’ll share a couple more in a post or two, but look at some of the pieces I snapped pictures of for you. They are done with packing tape! Yes, packing tape. That brown thin stuff you know well… It was part of a series of scenes from noir films, rendered in this way. Very effective indeed, I felt. The series name is “Tape Noir”.

Another meteor shower is almost upon us. Next week it is the turn of the Leonids. Now, as the name implies, these have their apparent origin in the constellation Leo. So how visible it will be for you, if you live in an urban area, might depend upon Leo’s position in the sky relative to your local bright city lights at the time of viewing. But it is worth trying. Look for a public park, rooftop, or other open area of sky. Parks can be better for pulling you away from some of the immediate lights, and then sit still and look at one patch of sky steadily for a while (generally in the right direction!) To get Continue reading ‘The Leonids are almost here!’

Aha! So you were thinking the mission last month was a bit of a failure, right? Because there was no big splash (literally) of a plume for the press to gush about? I’m talking about the October LCROSS mission on October 9th that smashed an impactor onto the moon’s surface (at the Cabeus crater) to create a cloud of dust for analysis. I remember people thinking, encouraged by various reports, that the event was rather a damp squib, since it did not produce a Hollywood-style flash and plume. See an NPR report on the mission here from back then.

Well, science is known for being able to carry on steadily even if there are no overt special effects and a catchy soundtrack. Today, NASA announced that their analysis of the data produced from measuring the dust cloud’s properties has shown very definite signs of water (confirming and strengthening the results accumulated by other missions (India’s Chandrayaan-1 and NASA’s Deep Impact and Cassini probes) that I Continue reading ‘Wet Moon’

On NPR’s Morning Edition the other day there was an interesting piece by Nell Greenfieldboyce about a lovely piece of research on the effects of various cultures of microbial organisms in our stomachs on how we extract nutrients from food. The key point is that what lives in our stomachs and how it interacts with what we eat is a key consideration in worrying about issues like nutrition, obesity, and other issues. I recommend listening to the audio of the piece, which you can find (along with a transcript if you prefer) here. (Actually, while searching for the audio for the story I found a related story by Robert Krulwich from almost exactly a year earlier. You can listen to that here.)

You may recall my mentioning a desert trip to shoot something for TV, some time back. One done at precisely the wrong time of year. And to Death Valley, one of the hottest places on earth, to boot. Well, I meant to mention that the episode of the History Channel’s The Universe that the shoot was for aired a week or two ago and it was really excellent. It was entitled “Liquid Universe” and it was a rather beautiful and thoroughly pleasant episode exploring the role of liquids in our universe, a matter not often raised in questions of astronomy except when it comes to matters of water from time to time. This was not about water per se, but rather the whole matter of material that flows and the role it plays in diverse areas of the solar system and perhaps the universe at large. I was using sand to demonstrate how sometimes there are surprising places where you can find fluid/liquid behaviour, and mentioned some of the new phases of matter found in the context, for example, of quarks and gluons at RHIC. (I’ve spoken about that here a number of times in the context of some of my research. See the archives.)

It was an excellent episode and another example of how one can take a topic under the “The Universe” heading and showcase lots of exciting science quite accessibly Continue reading ‘The Universe: Cool Cars, Hot Sand, and Fast Balls’
