Just for Me

As they did with the Incredibles, Brad Bird and the team at Pixar made a movie just for me! No, really! How could they know so accurately about my likes, loves and interests in conjuring up such a perfect combination of the various themes, story elements, images, scenes, characters (and rat facial expressions and gestures)? This time it is all about food - good food - cooking, and kitchens, and you know how I feel about those topics.

Ratatouille is wonderful and I imagine that (even though they made it just for me) you Continue reading ‘Just for Me’

Taco Medley

While on the way to see a film celebrating good food (among other things) it makes sense to have some. This is Lotería’s taco sampler (click for larger):

iPhone Madness

As you might have guessed, I could not resist having a look at the line for the iphone at the Grove shopping mall/village/whatever. Here’s an overhead shot of a cluster near the Apple Store’s entrance just after the launch at 6:00pm:

line for iphoneWhat you can’t hear is people cheering as people either enter or emerge (with their new acquisition) from the store (I’m not sure which). It’s not everyday you see this many people (in a very long line indeed - see one of four segments at right) waiting to shell out so much money for something that they all know will be very obsolete a year from now. They just want to be part of what is (seriously for a moment Continue reading ‘iPhone Madness’

Making Real those Imagined

la bloggers liveA few hours ago, I got back from a rather pleasant event - LA Bloggers Live! What was it? LA Bloggers Live! Exactly what it says on the packet. So there were several bloggers from the Los Angeles area who met (at Tangier) to read out loud some of the posts from their blogs, listening to each other and meeting each other in the “real” world, as opposed to online. It was really great - there were several great readings, and it was excellent to meet and chat with some of the people whose blogs I’ve read from time to time. It was good old-fashioned community, plain and simple. There were readings on lots of topics, from joy and pain in relationships to learning how to swim and ride a bike as a child - the hard ways. Over on Leah Peah’s blog (she conceived and organized the event) (and also here) you can see the list of readers, and later there’ll be some links to the posts that were read along with some audio. (I was particularly pleased that Will Campbell, whose blog I read from time to time, read a post that I recognized fondly - in it he’s on his bike, and he gets to do one of those things that all cyclists have wanted to do at least once, Continue reading ‘Making Real those Imagined’

Rapid Changes in Los Angeles

Good News, Everyone!

Well, you know (if you’ve stumbled upon one of the posts in my long series of attempts -see end of this post- to remind one or two people that they should not believe all the myths about LA not having any public transportation) that I’m continually excited about the steady stream of improvements that are being made by Metro in response to the increased pressure of usage put on the system by the general public.

local long busWell, in addition to adding more and more of the red “Metro Rapid” bus routes*, which are faster than the locals (which -ridiculously at times- stop every block) because they stop mostly only at major intersections, and in addition to adding more of the nice and roomy double buses (”bendy buses”) they’ve done something just great (which I’d been hoping for for years) - introduced true express routes! It makes sense to have three levels of granularity on the bus service here since it matches the three levels of granularity on the road system! Continue reading ‘Rapid Changes in Los Angeles’

Philosophia Naturalis

powers of eleven distance scale chartI noticed that the eleventh edition of the blog carnival Philosophia Naturalis has been posted at Highly Allachthonous. Do follow the link and have a read of the various Physics (and related) posts that have been collected there*. The host Chris Rowan has organized things by distance scale (in powers of eleven!), and it’s at least worth seeing how he used the chart on the right. Also, you can read past such carnivals here at the home blog.

SciTalks

I learned from Jonathan Shock and Sara Tompson about SciTalks. In Jonathan’s words (from a comment on another post):

There’s now a site where people can link to, review and rate scientific videos online. This is a great step as there are so many wonderful lectures online but currently they’re spread all over the web and it’s always hard to tell the quality and level that a lecture is going to be.

Jonathan has also done posts about online resources in theoretical high energy physics, including a recent one where he discussed SciTalks a bit more.

jennifer goldbeck on the semantic webThis got me thinking a bit about where we are going with all these resources, how useful they are, and -very importantly- how easy it all is to find, and then to search through. (Imagine there are 10 hour long talks broadly on your favourite topic. Assuming there are no accompanying files, how can you search them to find a specific fact that they might mention, without sitting through ten hours worth of material?) Well, ironically, one of the first things that caught my eye on SciTalks was a rather nice talk by Jennifer Golbeck (given at FermiLab last year) entitled “Social Networks, the Semantic Web, and the Future of Online Scientific Collaboration”. She’s quite interesting about this very topic… She describes online collaboration, data sharing, social networks, etc, all in the context of helping us do science (not just physics by the way!). She also illustrates her subject matter -still staying on topic- using examples of data sets from Facebook, Myspace, Friendster, Continue reading ‘SciTalks’

99

The other day in the Hollywood Farmer’s Market I was having my regular moment of pure bliss (spinach and corn tamale from that amazing tamale stand) for lunch after a nice bit of shopping when I found myself sitting at a big outdoor table with a number of other people. Two of them were headed to the convention center for the afternoon and were wondering whether they might be able to find anything good to eat down that way. Of course, as a public-spirited person I had to tell them a bit about the options that popped into my head at that point (starting with La Taquiza of course), and ended up patiently explaining how to squint your eyes to look past all the fast food places to the culinary bliss that lurks just below the surface of the city. We had a delightful conversation and then they moved on, leaving me soaking up the sun for a while longer.

image from Jonathon Gold's 99 restaurants articleA woman who’d been sitting on her own (also enjoying a tamale) spoke up and said that she’d been interested to hear that I thought there was a lot of good food in LA since she could not really find much of it (and she’d been here for four years). Happily I’d finished my tamale and so did not choke or splutter at this revelation, in equal parts horrifying and deeply sad, and spent a few more moments listing some recommendations at her request. Unfortunately, the conversation turned (as it so often does) to one where I find myself defending LA against someone’s expectations of it based upon their own city, and their own requirements (instead of them learning how to navigate and understand the place they’ve chosen to live). Usually it is New Yorkers I have this sort of conversation with, but this time it was someone from Chicago. Her thesis was that good food is hard to find in LA and you’re just falling over it in Chicago. Two other diners arrived (also with tamales that they loved, I’ll point out) and guess where they’re from? Chicago. And so on it went… next they were bonding with each other about their favourite places in Chicago, which was fine, but… I wanted to get back to this nonsense about good food being rare in LA. I hate that myth almost as much as the “no public transport” one (but not quite since it is not as dangerous and destructive)…and particularly despise that habit people have of worshiping the thing they love about their home city by dragging down LA. Can’t people learn to just like what they like without having to enhance it by trying to dislike something else, as though Nature has a conservation law about the total amount of “liking” that can go on? (Above, Anne Fishbein photo from an article to be discussed below.)

I find it a cheap and lazy practice, in general - although to be fair to the woman of this Continue reading ‘99′

Blogging Strings 2007

I’ve just noticed that Jacques Distler will be blogging from Strings 2007 (his first post is here). Excellent! I hope that others will be too. If you learn of anyone else who will be blogging from the conference (either physics content or other aspects of the event), do let me know (either in comments or by email) and I’ll update this post with pointers. If you have anything interesting to share from it*, but don’t blog, consider sending it along too!

(*You know, anything from supplementary physics discussion to incriminating photos from those notorious string theory after-parties that plague the conference circuit…)

Strings 2007

goya strings The main annual conference in my main field of interest starts today. Strings 2007 is in Madrid, and runs all week. The website is here (while there, have a play with the front page image of the Goya painting - quite entertaining - snapshot right). They promise to update the schedule/speakers page with scans of slides, and video, so you’ll be able to keep track of some of the new developments online. There’s no system for doing this live, or asking questions remotely, so if you want to quiz Ed Witten about his new 83-page monster paper on three dimensional gravity that came out yesterday (just in time for the conference!), or feel the buzz of event-anticipation whenever Witten talks about a huge new sets of results, you’ll still have to show up in person.

Why am I not there? Well, it would be nice, but there are lots of reasons I’m not going Continue reading ‘Strings 2007′

Mathematics and Strings

Not long after I told you about the TASI school and the excellent online lecture resource they were rapidly building, I heard* about a school in Utah that might be of interest, especially if you’re interested in the fruitful interface between mathematics and string theory. The title: “Derived Categories”, and it ran for two weeks with lectures on mathematical aspects and stringy aspects. The main reason I’m telling you Continue reading ‘Mathematics and Strings’

Morning Computations

morning computations…and then you have days when nothing works. At all. This was not like last Saturday. Despite starting out nice and early with a cup of tea in the sunshine and scribbling away while wrinkling one’s brow. Things got worse and worse through the morning, as I realized that many things I so wanted to be right about the next stage of my computation (which perhaps I’ll tell you about one day) were in fact not going to work. Not even close.

By lunchtime I’d given up, and summarized my thoughts on the research blog for my collaborators. Was probably not the most encouraging reading for them to encounter, but I tried to be as constructive in my deconstruction of our idea as I could. I’m hoping that they -or later, I- might find some useful threads to pick up on from my notes and remarks.

It’s not over yet.

Maybe I should have gone for that hike instead of sitting entirely at home on a Continue reading ‘Morning Computations’

Live Re-Entry

Is there a Perfect Pitch?

And the immediate followup question is “Should there be?” I’m referring to the story on NPR’s Marketplace the other day about the effects that some women’s voices have on whether they are taken seriously in the workplace. The audio is here, along with a transcript. The article, entitled “Professional women? With little-girl voices?”, is by Ashley Milne-Tyte.

The piece begins with a clip from the recent news, of Monica Goodling (Former Justice Department White House liaison) speaking in her defense during the hearings over the Justice Department firings. She has a noticeably “little-girl”-pitched voice. (I’m sure you remember hearing her during the news or the live broadcasts, and possibly your first instinct was to ask yourself why - in the political feeding frenzy aimed at bringing down Alberto Gonzales from the Attorney General position - the Congressional Democrats were now rounding up and grilling small children. (Or at least that was how it was for me for a split second since I mostly don’t watch television news - I find it too slow and otherwise annoying - and so I heard her on the radio.) It was then announced in the news piece who it was and I thought nothing more of it at the time…)

My own take on this is that it does not matter. You just learn, and move on. Since coming to the USA long ago, I adjusted my expectations about what are considered Continue reading ‘Is there a Perfect Pitch?’

The Two-Body Problem

Ah, the two-body problem. On NPR’s Marketplace last week, Kai Ryssdal had a piece entitled “Studying ways to help 2-career couples”, covering a “Dual Careers Conference” at Cornell. The audio is here, along with a transcript.

It’s an important issue, (which I’m not going to spend a huge amount of time on here, since I’ve been blogging too much this morning so far), and I’d no idea that there were conferences devoted to it.

From the point of view of academia, there’s one aspect of it which still has not penetrated very far in the minds of many, in my mind. It is one I tried to emphasize when this issue came up during various advisory committees I’ve served on with relevance to matters of hiring, diversity, etc. What’s on my mind is that the two-body problem (as it is jokingly referred to by some) is not always to be thought of as a “problem” from the point of view of potential employers. In fact, if you can work with a potential employee to find employment for their spouse at your or a neighbouring institution, it actually can strengthen your faculty roster in many ways. Aside from the obvious ones, there are the benefits of having happier employees who are committed to setting down roots, rather than an employee who is spending a lot of time travelling to or calling their spouse in another city, wondering every day whether their job is really worth that strain. Retention is a huge issue in managing your faculty. The value of settled employees cannot be overstated if you take the long view for your organization.

Anyway, have a listen to the article (or read the transcript). There’s the usual interview with members of couples who are academics and struggling with the issue, and it’s interesting if you’re not familiar with the matter, or perhaps if you’re in academia, early in your career and wondering about what the job market holds for you. And if you’re currently wondering whether to date other academics or not, don’t be put off (at least not by this issue!). Things are getting better. Employers are getting smarter Continue reading ‘The Two-Body Problem’

Gotta Love the Arclight!

silver surfer arclightsilver surfer arclightWhat was he surfing on anyway? Magnetic fields? Or just an all-pervasive Jack Kirby/Stan Lee medium? Or perhaps I’m making the same mistake that Nineteenth Century physicists made, thinking that light waves needed a medium in which to propagate? That’s it! The Silver Surfer needs nothing to surf on… Huh, why did I not think of that before?

Loud Laughter About To Happen

This is quite brilliant..! (Be patient… it gets even better as it goes along. Some familiarity with the Star Wars films required for full understanding, I’d say. There are some brilliantly conceived extensions of various scenes, excellent re-imaginings of others, completely new added scenes (the John-Cleese-esque scene is just perfect, for example), and so forth.

Back To the Future

Chesley Bonestell fifties science fiction spaceshipThe BBC Radio 4 program Archive Hour was just brilliant on the weekend. Here is the synopsis:

Adam Hart Davies looks at some of the predictions made in the past by scientists, programme-makers and politicians about how future society and technology would develop. He explores some of the moral and ethical dilemmas arising from mankind’s thirst for new inventions, new technologies and new ways of life.

(Image right: Chesley Bonestell painting for a cover of The Magazine of Fantasy & Science Fiction in 1950. See more art from that era at this excellent site.)

It brings to the issue a lot of archival footage of interviews, debates, and other material. There are interviews with many interesting people, including scientists and science fiction writers. The role of science fiction (the really good stuff, not the stuff that’s purely space opera… although sometimes it is hard to know which is which without the benefit of hindsight) is discussed quite a bit too.

There are the usual discussions about mobile phones, communications satellites, and the like, well-known things that were anticipated by writers of fiction, but the programme is much more interesting than that, reflecting upon the impact of various technologies and medical techniques (e.g. heart transplants) and how they were regarded and debated at the time, since they were often seen as either assaults on, or enhancements of (depending upon point of view) our humanity. This discussion is all in aid of reflecting upon us in the present. (Consider carefully the face transplant, for example, and how people react to what that means…)

There’s also very interesting discussion of the moral/ethical responsibility of the Continue reading ‘Back To the Future’

Nooooooooo….!

A disaster of a few days ago:

It was on a window sill, and after shutting the window rather suddenly, my hand slipped down and severed the plant’s trunk! Drat!

Nuts and Bolts

notebook workingYes, part of my job is to sit and think about how the universe works. People hear this, and they wonder exactly what that entails. Well, it entails a lot of things - sometimes there’s the grand thoughts and the thought experiments and the like that you hear of from documentaries and books about Einstein and other famous scientists - but more often that not it is grungy nuts and bolts.

Take yesterday for example. After a week of working on various calculations and chipping away at improving my understanding of how to approach a certain problem, I decided to take Saturday and be outdoors a bit more…see what it was like outside. You know…. Have an actual Saturday Saturday. (I did not end up being booked to do that TV shoot, by the way, so I had a nice clear day ahead of me.)

What actually transpired was this:

Sundogs

Yvette (one of our regulars here) let me know about a photograph that she took of a sundog the other day. It appeared on the Spaceweather website (you’ll need to set the calendar there to June 14th to see it in context), and since there may be a few of you (like me) who wonder what a sundog (or sun dog) is, here it is:

sundog by yvette cendes

Yvette also put it up on her blog (which is an interesting and nicely illustrated read, by the way) together with a picture of the broader view showing the nearby sun.

My confession today is that I had no idea that is what those optical phenomena were called! No, really. You’ll also find them called parhelia (the plural; singular “parhelion”)…. they are always near the sun, you see. (Less common are the images that form somewhat further away from the sun (a “paranthelion”), or quite a bit further away (an “anthelion”). These are not, as I understand, properly referred to as sundogs.). I always used to wonder about them (and their cousins, the halos you sometimes see around the sun) when I was a child, but never talked to anyone about them back then (I kept a lot of wondering to myself) and the urge to find out what they were called was never strong enough I suppose. I think I’d satisfied myself that they were caused by refraction in the atmosphere, but again, I’ll admit that I’d never really gone and verified this anywhere. (Same for the effects around the moon you can sometimes see.) So I never learned of the significance of 22o, which is the angle the light from the sun bends through when it passes through the hexagonal ice crystals floating in concert in the upper atmosphere. (The other, further away ones are formed at larger angles.) It was when Yvette said sundog that I went a-Googling (as one does) Continue reading ‘Sundogs’

Name That Particle!

As a followup to the post on Roz Chast’s Symmetry magazine cartoons, I get to tell you* about a fun competition! The prize? A Roz Chast autographed copy of the May edition of Symmetry magazine (yes, that’s the one she did the cover for) and an appearance in a later edition of the magazine!

You can find the entry details at Symmetry magazine here, and I quote:

roz chast on physicsFlerbs? Marteenies?? Tom, Dick, and Harry???

Cartoonist Roz Chast has busted the field of particle physics wide open with her pioneering cover for this issue of symmetry. We say it’s about time: Why limit ourselves to the same old list of particles that have actually been discovered, or at least properly theorized? So here’s the challenge: Invent an elementary particle and tell us what it does in 30 words or fewer. A drawing would be nice, but not mandatory. […]

Reality Calls

american inventor logoIn a bizarre twist, after a satisfying day of calculating I switched on the television, accidentally pressed a wrong number, and ended up on ABC just as a program called “American Inventor” was starting. I’m not really up on all these “reality” format shows, so I’ve no idea how long this has been in existence, but I must say that it was good to see a program in this format that was primarily about using one’s brain, inventiveness and engineering/construction skills! The format is a bit too gimmicky for my tastes (I’m not partial to all the fake drama and overwrought background music), but that’s probably because I don’t watch much of this sort of thing, so I probably won’t be a regular viewer. But again I must say it was good to see that such a show exists. Perhaps there are more that I don’t know about. It seems that I just saw the phase where they filter out all the silly ones (and goodness were some silly!) and pick the finalists from each city who get $50,000 worth of development money. They did LA and SF in this show, and apparently they’ll be doing the North East next. Questions you might be able to help me with: Do all these shows have a British judge on the panel to play a sort of mean guy? Is it a sort of requirement? The one other such show I’ve seen, American Idol, has that, and like a good theorist I am extrapolating wildly from two data points.

logo for design squadSeeing a reality show based on some intellectual skill actually reminds me. Even though I got a reminder from some of the people behind the show, I’m embarrassed to say that I completely forgot to tell you about the show on PBS for youngsters aged 9 - 12 called “Design Squad”. From the “about” part of their site:

Borrowing from the hugely popular reality competition format, DESIGN SQUAD is aimed at kids and people of all ages who like reality or how-to television. Its goal is to get viewers excited about engineering!

Over 13 episodes, eight high school contestants tackle engineering challenges for an actual client—from building a machine that makes pancakes to a “summer sled” for LL Bean. In the final episode, the top two scorers battle for the Grand Prize—a $10,000 college scholarship from the Intel® Foundation.

I think it has now concluded, but you can watch all 13 episodes online here. Did anyone see it? (I did not.) What did you think? You can get more involved with Design Squad by following up on this part of their website.

Design Squad was co-sponsored by the IEEE, which is excellent to see. So will the American Physical Society (and other science societies) be doing something similar, one wonders? It’s a potentially good way of getting people interested in participating in science - on prime time television. We could, for example, have members of the Continue reading ‘Reality Calls’

New Toy Tool!

Trying to calculate all day long. Lunch break. During this moment of procrastination, I thought I’d tell you about the product of yesterday’s procrastination. At some point in the morning I decided that I was not thinking straight about aspects of my computation (like what it all means), and that this could be helped by having a bigger space to work on that I have at home right now.

I don’t know about others, but sometimes in addition to the need to change venues during research thoughts, I also need to change the medium I’m writing on. So at lunch I went shopping and after visiting far too many stores (art supply for one part, office supply for another) to get the right things, look what I got (see left picture)!

Otherworldly Top Ten!

extra solar  planet GlieseAfter reading an article about how the “trickle of planet discoveries” as become a “flood” -referring to the many discoveries of extrasolar planets that are being announced these days, since they first started being discovered in 1995 1988/9 (there are more than 200 known now)- I looked at space.com’s “top ten most intriguing extrasolar planets”.
[Update: First detection of extrasolar planets is probably more accurately to be dated 1988/9. The first confirmed one was in 1995, but the planet Gamma_Cephei_Ab, detected in 1988(9) by two separate teams, took until 2002 to be confirmed. See e.g. here for more. Thanks commenter molliska!]

Have a look at that interesting article about the pace of discovery, and then when you’re done, peruse the top ten here. You’ll find:

  • 10: 51 Pegasi b, the first confirmed (see above update) one found, 1995;
  • 9: Epsilon Eridani b, the closest known one (only 10.5 light years away);
  • 8: the class of planemos, the extrasolar planets which are not orbiting any stars;
  • 7: SWEEPS-10, a “zippy” planet, that orbits its star every 10 hours as opposed to our sluggish 365.25 days;
  • 6: Upsilon Andromeda b, a planet which is tidally locked to its star so that it presents only one face to it all the time. So one side is always super hot, while the other is very cold;
  • 5: The youngest one known (it’s been in existence a bit less than a million years), orbiting the star Coku Tau 4;
  • 4: PSR B1620-26c, the oldest one known (12.7 billion years…wow!);
  • 3: The “shrinking one”, HD209458b, that orbits so close to its star that it’s Continue reading ‘Otherworldly Top Ten!’

Amusement With Physics

I learned from an NPR report today on Day to Day (by Robin Sussingham) that around the country there’s a nice combination of physics and fun going on in various amusement parks! You can hear the story here. From the website:

roller coasterPhysics students in Utah recently attended an event where they learned about concepts like acceleration, velocity, magnetism, and centripetal force.

But this was no boring science fair: It was Physics Day at the Lagoon Amusement Park, north of Salt Lake City. The kids tested theories by riding roller coasters and dropping raw eggs from the towering Sky Coaster ride.

One Utah high school that takes part in “amusement park physics” reports that it now needs three full-time physics teachers to meet growing student interest.

(”Boring science fair”. The cheek. Science fairs can be fun! Anyway, moving on…) It’s an interesting report. It’s been going on for some time, and this event is organized by the Utah State University Physics Department. I also found a report in the Deseret Morning News by Tammy Walquist, which was quite informative. (Photo above by Laura Seitz, of Jessica Rocha (left) and Shelese Sheffield, Kaysville Junior High eighth-graders, is from the article.) An extract:

Amara Graps: What happened to Bush’s Cadillac One?

amara grapsNow for something a little different…

I’ve been trying for some time to get one of Asymptotia’s regulars, Amara Graps, (click on image to the right for larger view) to give us a guest post. She sent me one by email, somewhat unexpectedly, a couple of hours ago, and I must say I did not anticipate the topic!

So here we have it… Amara telling us a bit about certain recent events in Rome. Enjoy!

-cvj

_________________________________________________________________________________

What happened to Bush’s Cadillac One?

As recorded by a viewer of the motorcade and posted to YouTube [jump to 3:15 point to get to the main event]:

It apparently sputtered to a stop. It broke down, right there, on via del Tritone (near the Trevi fountain) in Rome, in the middle of the motorcade. He was ripe picking for a sharp shooter too; no wonder the police were pushing people further back, off of the street. It looks like the solution was to switch limos, because he got out of the limo with Mrs. Bush and climbed into another one.

This is a very special car. If it is a mechanical failure, then the manufacturers have a lot of explaining to do. His visit to Rome had been preceded by a large security operation (perhaps inconsistently). The Tiber was dragged. The sewers were searched. Squares were cleared and roofs occupied. The presidential motorcade Continue reading ‘Amara Graps: What happened to Bush’s Cadillac One?’

Entertaining Saturday

Eight o’clock on Saturday morning. I’ve been up since before six (I don’t know why) and somehow I’m still late. The car wakes up easily, eager to go for a run. It seems to have extra enthusiasm, as though it knows that somehow I’m going to tear all the way across the city and back as quickly as I can, an adventure it is always willing to participate in. I’ve got a guest coming over for lunch at eleven and I think I’ll assemble a nice meal from scratch. I’ve made my mind up to go for ingredients to the Santa Monica Farmer’s Market instead of the more local, smaller one in Silver Lake. Although I’m more of a fan of shopping locally, my usual market run is on Sunday, in Hollywood, and the Silver Lake one does not have most of the vendors that I know well from the other two markets, and I want to take no chances with my menu today. So, the highway for me this time.

The plan is to wander the market in head chef mode, looking for which items look good, choosing some of them and planning something simple and tasty around them. At the back of my mind is a salad, and maybe asparagus or artichoke as a central feature. I’m open to ideas, however, but the watchwords are fresh and simple. But I’ve got to get there, find the ingredients, and get back and make it all before eleven.

farmer's market and saturday lunch menuI break some kind of record for getting over to Santa Monica. Road was pretty open, and while I’m not saying whether I violated any speed limits, you can be pretty sure I hurt their feelings a bit. The market is still pretty empty and I can wander through at a good pace with my basket and check out the whole scene, retracing my steps on a second pass in reverse, this time buying things as I go. Three different kinds of tiny potatoes to form the base of a salad (after roasting them) along with two colours of carrot from the same people. For dessert I pick up three types of delicious berries -blackberries, strawberries, and blueberries- making a mental note to get some whipping cream (for hand-whipping later) as a topping.

Yellow Pear Tomatoes

Tasty yellow pear tomatoes (click for larger):

tasty yellow tomatoes

They have been showing up all of a sudden (it seems) on this plant from last year. I’d read that this is quite a hardy plant and it certainly is, lasting through from last season, through the cold snap, and now coming back more strong than last year. Apparently, it is quite an old variety, going back to at least the 1750s.

Griffin Apologizes

Interestingly, NASA’s chief administrator, Michael Griffin, apologized for his somewhat bizarre remarks of last week. What remarks? The ones that (among other things) essentially sidelined a huge amount of the work people in his own organization are busy with. See here for a reminder. He made his apology at JPL on Monday:

TASI@Home

This year’s month-long Theoretical Advanced Study Institute -TASI- looks especially good, from my point of view, with a great combination of topics and lecturers. As usual, it is held in Boulder, Colorado. It’s all about current ideas and experiments and observations in particle physics and cosmology. Three USC students are there and I’ve heard from them that things have been great so far.

raphael bousso at TASIWell, the great news is that the TASI people are making the lectures available online a fairly short time after their delivery. The link is here. So even though not there, you can schedule some time to take these lecture courses if you like. I glanced for a while at Raphael Bousso’s first lecture in the series “Cosmology and the Landscape”, and it was clear and very well presented. (This is not entirely surprising - Raph is always an excellent lecturer.)

Hunting the Higgs is not a (D)Zero Sum Game

D0 data shotWriting in Slate magazine, James Owen Weatherall seems a little confused about how particle physics works. Based on a rumour that there’s a new and significant signal seen at the DZero detector at the Tevatron at Fermilab (Illinois), one of the article’s titles is “Why the rumored discovery of the Higgs Boson is bad news for particle physics”. Supposedly, the big new machine, the Large Hadron Collider (LHC - see more about it here, and what physicists are hoping for from it), about to switch on later this year, would have nothing to do, and would be a waste of billions of dollars. You can read about the original rumour here. (Above right: A random collision event I grabbed from the DZero experiment.)

Well, this is wrong for so many reasons. It is hard to know where to start with this. The major fallacy with the whole thing is that these machines are just somehow discovery devices (in the most naive sense) of some sort. You build it, switch it on, see what’s there, write the paper and the press release (not necessarily in that order) and then you’re done. Completely neglected is the notion of such an experiment as a device for Continue reading ‘Hunting the Higgs is not a (D)Zero Sum Game’

Wave It Like You Just Don’t Care

Although we care deeply. It’s just late, I’m a bit woozy as I write this, and so I’m stretching a bit for a good title. This post is about gravitational waves. More accurately, it is about a rather good BBC programme about gravitational waves: What they are, why they are important, why we care, and what we’re doing to detect them. It’s Melvin Bragg and some guests on the “In Our Time” prime time programme. I recommend it as a pleasant, unscripted chat which has quite a bit of good introductory information. Even if you’re a bit busy, you can listen to it while doing some other task. Go on. Also, even if you know this stuff, it’s always amusing to hear the host apparently getting terribly confused and hung up on some points while trying to get to grips with the material. I can never tell if he’s faking it because he has decided that he has to reinforce the cliché -it’s physics so it must be hard, especially at this time in the morning- or whether he’s for real at these points. Either way, it makes for a rough-and-tumble conversational feel to the programme which is not altogether disagreeable.

Anyway, the key thing is this (and you’ve probably not heard this here first): In the entire history of science, every time we’ve figured out a new way of looking up at the sky, we’ve revolutionized our understanding of the universe. We’ve every right to expect the same of gravitational waves, once the technology matures. It’s exciting just thinking about it!

I’ll end with some relevant things to look at. Above is part of the LIGO detector (photo from NASA’s website). Here’s a link to the LISA detector that everyone hopes will Continue reading ‘Wave It Like You Just Don’t Care’
