I’ve spoken about Haruki Murakami, one of my favourite writers, here before (Image right by Elena Seibert). See my earlier post, which highlighted an essay of his. Well, I learned from The Writer’s Almanac that it is his birthday today. Since I’ve been thinking a lot about great writing recently, I thought I’d celebrate by noting it here to you on the blog. Do go over there and read a bit about what Garrison Keillor and his writers say about him. Extract:

Yes, still with the morning baking. I feel a bit bad about not getting bagels from Brooklyn Bagels (on Beverly) anymore (after six years of being a regular), but there’s only so much I can eat in baked goods and I seem to be in the mood to do it all myself these days.

Not sure why I’ve never done these before:

Sweet potato biscuits*. Perfect for using up that left over sweet potato, and, like all Continue reading ‘Nine’

I’m taking a short break from it while I wait for my soup - that wonderful soup I made a huge vat of last night, using the essence of the left over carcass of a roast chicken I served on Christmas day combined with various delicious vegetables from the farmer’s market - to heat up for dinner. I need the break, as I’m mentally exhausted. Although I strongly feel like having a nice evening glass of wine, I am forbidding myself from having one since I must stay sharp for much longer this evening, despite my exhaustion. So a bit of blogging about my ongoing task will somehow serve as my relaxation. Oddly enough. Well, let’s see if it does.

I’ve been wandering an incredibly striking landscape, with such remarkable variety, detail, texture and hue. There are features that move me to tears at times, reduce me to fits of uncontrollable laughter at others, but mostly intense reflection throughout. I should be simply enjoying it for its own sake, drinking it in where I want to, letting it simply wash over me at times, while at others, cupping some of it in my hands and looking at it close up, before letting it flow away and moving on. But I do not have that freedom. Instead I have to look at it all with a view to ranking various features over others - putting it all into some sort of order. This is a terrible task to have to do, since so very much of it is simply wonderful in its own right, and there’s hardly any meaning to ranking some parts over the other.

What on earth am I talking about?

Well, as is so often the case with some of the things I get myself involved in, I can’t tell you much detail, since the process itself is ongoing, and rather sensitive. I’d not Continue reading ‘The Read’

So have you been to Griffith Park recently? I went for a short hike there this morning for the first time in a month or so. The first time this year. (I’ve not been hiking much the last month due to several things, including waiting for a full recovery from my mysterious vertigo which still pops up from time to time…)

Well, I had a nice hike, and cleared away some cobwebs in my head, which was nice to do. I’m in the middle of writing two research papers, and reading a great deal of material for a search committee I’m on (meeting imminent) and so a bit of clearance is good.

The thing is this. The park was with teeming with people, of a broader range than is usual for the park, in those numbers. Not sure why, but it was good to see. Is it all those New Year’s resolutions? People resolving to use the city’s wonderful park areas Continue reading ‘Back on the Trail’

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’

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.

This is Yun Zi, (”Son of Cloud” I hear) who arrived in the public eye (at five months Continue reading ‘Smarter than the Average Panda?’

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’

(Since it is bowl season…)

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 Continue reading ‘Happy New Year!’

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’

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 Continue reading ‘Wants and Kneads’

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’

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 Continue reading ‘Jetlag Benefits’

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’

Well, I’m back.

It is early in the morning, at home. At 5:30 am, with my first cup of tea in hand as I breathe in deeply and simply listen, the rest of the City of Angels seems asleep still. It is covered with a fluffy blanket of grey clouds, and it looks strangely snug under it.

It has been quite the trip, as you may have gathered from the past several posts. I managed to get a great deal done in that last day or two, as I was planning when I last reported in. This included more food, jazz, some flamenco in two unexpected but fascinating settings, the excellent collection at Reina Sophia (focused mostly on Picasso), and more.

I’ll try to tell you some of it in the next few days.

But now I must focus on being back. I spent a long day travelling back from MAD to LAX yesterday and need to recover and get on with business immediately. There is a final big lecture for my Electromagnetism class to write and deliver, for example. All Continue reading ‘MAD to LAX’

I spent an astonishing stretch of time in the Prado on Saturday, in an operation that experience and aesthetics have taught me to pace properly. I pick a particular artist or cluster of artists and focus on them for an hour or ninety minutes (visiting the parts of the museum that are relevant to them, not focusing on anything else, more or less), then I find the cafe, get a cup of coffee and a tasty, and relax for a bit, glowing from the experience. Then I plan the next pieces of the museum I will visit next and begin my focus on that part. The temptation with a museum the size and complexity of the Prado, with the remarkable depth it has in its collections, is just to show up and try and see everything in whatever order you find them. This results in confusion, superficiality, and major headache and backache, at least for me. I’m happy to go in and see a subset of what is there really properly and in context rather than just “see stuff”.

So of course I mostly focused on Spanish painters - several of the masters before the 20th Century - and later, other masters who perhaps were creating work in a Spanish context of some kind, and later, particular masters who happen to have examples of some of their great work housed in the Prado, whether there be a Spanish context or not, of which there are several such examples.

The collection is amazing. About 1/3 of my time was spent on Goya, in fact. (I wisely Continue reading ‘So Much To Do…’

Well, the weekend is here and so I have wrapped up most of the official part of my visit to Madrid. Lest you think that I spent most of my time eating (not that there’s anything wrong with that), let me mention that I ended up, from Monday to Thursday giving about eight hours of detailed exposition at the board and fielding questions (the lectures and seminar), umpteen (an official number, I’ll have you know) hours of preparation of the notes needed to do this in a successful and clear way, and several more chunks of time in private physics conversations of various sorts. Quite fulfilling, tiring, but worthwhile for all concerned. (I even heard that various people liked the lectures and the seminar, so that’s a real bonus!) It has been a good week.

Thursday night saw me wandering the city streets in the drizzle for several hours. It all started out with a quick walk near my hotel to see if I could stumble on a restaurant, but eventually turned into a longer walk and then an epic quest, as happens to me so often in such situations. I start applying a list of criteria for what I Continue reading ‘Less Work, More Play’

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:

Continue reading ‘Wham!’

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”.

As you may know from earlier posts, I love markets, a place where people come together with lots to see, talk about, interact over, and of course to taste. Community. One of my favourite things. Here’s a lovely stall at Granville Island in Vancouver when I was there briefly a short while ago. (Click for larger view.)

I can’t resist showing you this display: (Click for larger view.) Continue reading ‘Market Matters’

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!’

I’ve learned over the years that news about public transportation often does not reach people in Los Angeles who aren’t already inclined to use it (that’s a lot of people) and so I ought not to assume that everyone’s heard about the exciting events of tomorrow. So here’s a quick post to let you know that the new Eastside extension of the Gold Line opens tomorrow! This is very exciting indeed! Spread the word! There’ll be lots of events to celebrate during the course of the day, and you can learn a lot about them at this link. You can ride the whole Gold line free to explore the system.

Those of you who will no doubt continue to insist that public transport in Los Angeles will never have anything to do with you (until there is a personal stop with a single-person train carriage right outside your home and a corresponding one wherever you want to go) can also join in the fun (just for the day, you understand) and come to the farmer’s market, see the bands and the people and so forth, and confirm your familiar position that it “won’t work for you” because it “doesn’t go anywhere”, just like the rest of the entire system supposedly doesn’t.

Soon, I’ll be doing a post on progress that has been made in recent months on the Expo line, by the way. That’ll be another celebration when that opens in late 2010 Continue reading ‘More Gold for Everybody!’

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’

Despite the title, which is also the title of an utterly depressing but wonderful song that I love, which starts out: “Sunday is gloomy/my hours are slumberless/dearest the shadows/I live with are numberless/…” and wallows in further and darker gloom for the rest of the song until near the end, I mean gloomy here in a neutral way.

It applies not to my mood but to the skies over Vancouver on the Saturday and Sunday set aside for wandering and exploring. I actually found a lot of it quite refreshing (recall that we’ve not had much rain in LA all year) and managed to see several beautiful scenes made all the more lovely for the shades of grey provided by the rain and clouds. The scene with the boats above left is an example. Overall I had a great time exploring, and was shown some nice parts of the city by my hosts, Moshe Rozali and his family (thanks guys!).

The trip was a success, in that I had a lot of great conversations with various people about physics research matters, and also in terms of the main point of the trip which Continue reading ‘Gloomy Sunday’
