….In which Crystal and many of the crew chill out on the sofa after a long hard season of shows and express some of their gut feelings about the whole business. Well done on an excellent series of shows, Crystal, Patrick, James, and all the other behind the scenes people! (Warning: – This episode may not be for the squeamish!)

Well, since yesterday was all about eating here in the USA (Thanksgiving, in case you missed that), I thought I’d share a partially inked panel from The Project, of a meal in progress. I got a bit of quiet time to work on it this evening, while listening to Jimi Hendrix and then Freddie Hubbard. They helped a lot. It is at times like this I wonder what insanity has come over me […] Click to continue reading this post
This episode of Fail Lab gets down to the bone of the matter: Failure. The whole point of this excellently conceived series was to look at the fail videos all over the web (as everyone does) and instead of just laughing at the people in them (as most people do), take a different path and try to see the positive in the failure. Sometimes with humour, and/or with tongue in cheek, but with an eye on looking at things a bit differently. Now this special episode turns and looks the issue directly in the eye. I have the honor of being a co-presenter of this one again, again with the excellent Crystal Dilworth, and this time we break the pattern and have yet a third person as a co-presenter – Adam Steltzner from JPL, the chief engineer of the landing stage of the Mars Curiosity mission, you might recall. Crystal and Adam are on the left. (You might also recall that we teamed up for an event earlier this year at the Natural History Museum…)
Together, we talk in the episode about the whole idea of failure, making mistakes, and of course, experimentation. We highlight how it underpins all innovation, scientific, technological, artistic… all corners of human […] Click to continue reading this post
Did you hear about the “takeover” of Seventeen Magazine’s Manicure Mondays? Hearing about it really made my morning*. I read about it in Slate. Go and look at some of the photos on twitter (you don’t need an account to do so) – It is a great variety of images showing hands (male and female) doing things, including scientific activities from field work to lab work. A rather excellent enhancement of the intended scope of just having nail-art.
Jason Bittel, who wrote the Slate piece, says at one point: […] Click to continue reading this post
Fail Lab Episode 10 is available on Discovery’s Test Tube Channel, or on YouTube. It focuses on responses to dangerous situations. Crystal Dilworth and Heather Watts do a great presenting job once again, and as a bonus, the brain-dog makes an appearance this time!

I’m preparing some notes for my graduate Electromagnetism class, and I’ve finally arrived at the section on Special Relativity. We will end up discovering the fully covariant formalism of the equations of electromagnetism in a few lectures, and a number of mysterious things we’ve seen over the course of the semester will be more natural in this setting, showing how marvellously Maxwell’s equations from the 19th Century, unifying Electricity and Magnetism, actually herald (actually should out loudly for!) Einstein’s 20th Century physics – Special Relativity.
But first I must review Special Relativity, going back to the basic thought experiments I like to talk about that lead you to discover it. Traditionally this means lots of scenarios involving flashes of light, and long extended objects being boosted at speed in various directions and so forth… All very fun.
Well, over the years I’ve changed the characters in the scenarios a couple of times, and now I’ve firmly (as of 2012) left Harry, his broom, Hermione, and [...] Click to continue reading this post
(By the way, (spoiler alert) in the video they analyze this week, that looks like a bit like a Wing Chun move (and stance) to me… albeit a tad sloppy. And I note that it was used to end the aggression. A win for positive use of martial arts!)
I was sent* this delightful short film recently. It is by Shixie (Xiangjun Shi) done as a graduation project at Rhode Island School of Design. It seems that it won prizes – quite understandably! – at a number of short film festivals, including one about science communication (which reminds me of the one I run). The film is entitled “Why Do I Study Physics?” and it is a lovely piece of writing and hand drawn simple animation that’s very […] Click to continue reading this post
So I’ve been a bit quiet as I’ve had a lot going on. This includes preparing ten interesting slides to use as props for a talk I gave this evening to the USC Philosophy Club. It was entitled “Ten Things YOU Should Know About Black Holes”. It started with the original idea by Michell in 1783 (yes, really, that early!) and ended with topics of current research (what is the fate of the singularity? What really happens at a horizon? Etc., etc…) I spoke for a while and then fielded tons of questions, and am now (I am writing a draft of this on the subway train home – uploading later) suffering from a rather broken voice due to too much talking and projection…. Gosh. But it was fun. A really […] Click to continue reading this post
Here’s the next episode in the excellent web series Fail Lab, on Discovery’s Test Tube Channel. It’s all about testicles. Clearly no more motivation is needed to encourage you to watch. It’s in a slightly different style than the previous ones… An amusing format change, in fact. Of course, there’s still amusing shenanigans going on in the lab…

Fail Lab, the web series on Discovery’s TestTube channel that I’ve been telling you about, is growing in popularity. People are hearing about its unusual charms as an edgy, funny, quirky, smart vehicle for some food for thought and are going to see. That’s great. There was a review on VideoInk today that seems to “get” series creator Patrick Scott’s “Zoochosis” point of view that informs his particular style of filmmaking, and that was good to see (although I don’t agree that the hard science can get lost sometimes – this is the online world where the viewer can take charge – if you miss an idea, just scroll back and watch it again. That creates opportunity for density in making intelligent programs, and hopefully steers us away from shallow, lowest-common-denominator programming).
Anyway, episode seven is now up, and fueled by a remarkable video it delves into ideas about how we relate to each other, within and without social groups. Here’s the embed: [...] Click to continue reading this post
You’ll recall that I was in New York a short while ago to film some promotional material for a new TV series. It is called Big History, and it will be on History Channel’s H2 channel (and eventually on various international channels, but I’ve no idea which – similar ones to where you find the other show I’ve mentioned a bit, The Universe, I expect).
Rather than be primarily about astronomical and cosmological things, the show will focus each week on one of a list specific items that have affected our history, and take the long view about that item. How long a view? The longest known possible! So take something like Salt, and examine its role in civilization and culture, bringing in historians, anthropologists, etc… and physical scientists to trace that object back to its roots in the early universe… (the big bang, the cores of stars, etc.) Update: For you Breaking Bad fans, note that it’ll be narrated by Bryan Cranston, by the way.
Here’s one of the promo videos:
Managed to find a little time over the last few days to lay out, draw, and ink a page in The Project. It has been insanely busy for me, so this is a little bit of a triumph in stealing some time back. It’s actually the same seminar that you saw in earlier posts (here and here). Now it is over. It remains a tradition in our field to give a little round of applause after a talk, which I find rather nice and quaint. It was a pleasure to depict that.
It is a wider view of the room, which meant (aaaargh!) drawing even more faces and bodies than before. Then there’s the challenge of doing them in different states of attention, applauding, with different faces, bodies, states of dress, etc. When I come to paint it I’ll be wanting to pick colors that together communicate the right mood for the panel and for the whole page it is part of, and so forth. It can be daunting to do all those faces, bodies, shirts, feet, and […] Click to continue reading this post
I just spotted (a bit late) that Steven Weinberg (one of the giants of my field) has written a piece in the New York Review ofBooks entitled “Physics: What We Do and Don’t Know”. I recommend it. He talks about astronomy, cosmology, particle physics, and by casting his eye over the arc of their recent (intertwined) histories of ideas, experiments and discoveries, tries to put the Standard Models of particle physics and of cosmology into perspective.

Fail Lab Episode 6 has a lot of things blowing up, so that’s good, right? We actually had a lot of fun mixing in a little bit of comedy with the science. (See an earlier post I did after shooting this episode.) I hope you have fun watching it! As a bonus, everybody’s favourite, petal the brain dog, makes an appearance again. Well done once again, director/writer/producer Patrick and his team for their work on making it such a visual treat – and James, it was fun to write with you and Crystal!

Friday’s meeting was rather nice. There was a really good turnout (especially from UCLA) and so in the end we had the perfect combination of an attentive and receptive audience and four really good speakers. As per design of the whole thing, plenty of time was allowed for discussion and pedagogy, and so I got the feeling that people felt really comfortable raising points during the talks and also chatting further during the breaks and lunch and dinner. It was really good to catch up with friends and colleagues from groups in the area, [...] Click to continue reading this post
Oh! I forgot to mention that the next Southern California Strings Seminar is today! It is being hosted for the first time by the group at UC San Diego. (Thanks Ken!) There’s a webpage with the talk schedule here.
Now, better head there….
Creating a structure for benefit of the students (for no reason other than it seems like something that can do some good) – a structure in which they can participate entirely voluntarily, and after almost two months of advertising it, and showing up in all sorts of classes to tell people about it, doing interviews about it, and so forth, and not knowing if anyone really will be bothered to get involved… getting lots (still counting) of teams of students registering. With lots of enthusiasm in various emails! Thanks everyone! It’s going to be great to see your projects develop. I hope you enjoy collaborating on making films about science – it will stay with you throughout your careers as a hugely valuable and fun thing to have done. Thanks to those faculty and staff who helped me spread the word by circulating emails, letting me show up to your classes, suggesting ideas, etc!
Dealing with faculty and staff who, despite the jobs they hold, really don’t have much interest in a new structure put in place for the benefit of the students especially if it means even slightly going out of their way to help out… some would rather come up with mountains of reasons and/or rules why they can’t or won’t help, or why I’m making their life hell for asking them if they might. They helped make this all far more stressful and difficult than it really should have been. Ugh… is all I can say. UGH!

I realized just now that since I set a midterm exam on Monday for the graduate electromagnetism class, and since there’s only one midterm for the class, it really is… midterm. The semester is sort of half over already. And indeed, a glance at my calendar shows this to be more or less true. I’ve mixed feelings about this since on the one hand it is a busy and tiring semester and I’m glad to have it go by, but on the other hand… slow down life! What’s the rush!? Yes, I definitely keep wanting to make sure I stop to smell the flowers, or what’s the point?
The midterm itself (Monday, in class) was fun. Or at least, I found it fun to put together on the weekend. There were no complaints from the students, so I hope that means I got the balance about right. We shall see during class tomorrow, when [...] Click to continue reading this post
Tuesday means there’s a new episode of Fail Lab, the online series on the Discovery channel Test Tube that I’ve told you about! (See several previous posts, listed below.)
Today’s excellent episode is about rodents. This is a subject I care about a bit since I’m in constant battle with them in the garden, as some of you who follow that part of the blog know… This might be why I think the actual “fail” video this episode is based on is hilarious!! Have a look at the episode, which is a lot of fun:

Last night’s event was wonderful. The actors had such passion, and it was all done with great pacing and flow. This was a most marvellous play reading – the cast’s performances felt so fully inhabited by the text of the play that it hardly felt like a reading at all.
They (Nike Doukas as Margrethe Bohr, Arye Gross as Neils Bohr, and Leo Marks as Werner Heisenberg) and director Jack Rowe, should be very proud. They did very little rehearsal for this, which is makes it all the more impressive.
I gave an opening address* (and also introduced the evening**, as usual forgetting to introduce myself…) and the text of my address follows:
Good evening and welcome!
Yesterday, the Nobel Prize in Physics was announced. You might recall that it was for the discovery of the mechanism that gives all elementary particles their masses. A profound mystery about the universe was solved. While that’s a wonderful thing, and many people acknowledge that, many people don’t connect anything about that quest to understand the universe to themselves.
I’ve been thinking about the early 20th Century recently, and the development of quantum mechanics, as a result of re-reading Michael Frayn’s play Copenhagen. There’s going to be a staged reading of it tonight at USC, put on by the School of Dramatic Arts, and I’ll be giving an opening address. I sat in a bar late last night over a fine oatmeal stout, thinking a little bit about what I might say in the address, and I expect I’ll put the finishing touches on the brief sketch of ideas while sitting on the subway to work this morning. We shall see. I’ll try to remember to post the text of it here if it turns out to be not entirely dreadful.
I’ve very clear memories of this play, and my first encounter with it. I was lucky to get to go to a special pre-opening performance of it when it debuted in New York (in the year 2000) I and got to meet and talk to Michael Frayn (and if I recall correctly, Claire Tomalin) about the writing of the play at the after-party at Sardi’s – a very interesting conversation it was too. I also (by a happy coincidence) got to sit next to Freeman Dyson during the performance, and was able to glance over occasionally to see the delight on his face at seeing old acquaintances of his brought back to life. (Well, I learned afterwards that this was the reason for the delight…)

This is by far the most provocative (and cleverly playful with your expectations) of the episodes so far. See my earlier posts for background on this creative, playful, and grown-up web science series. (List of posts below.) Have a look at the new episide, and stick with it all the way through before passing judgement. Warning – if you’re of the squeamish persuasion, maybe don’t look at it over lunch.
Well done, once again, everyone involved!

This morning the 2013 Nobel Prize in Physics was announced, and it was given to Francois Englert and Peter Higgs for the 1964 theory of what’s now often called the Higgs mechanism, recently directly confirmed experimentally by the Large Hadron Collider at CERN (as you might recall) by the finding of the Higgs particle. You might recall that the mechanism, also associated with the term “symmetry breaking”, is responsible for the masses of the elementary particles, as has been discussed here and elsewhere a lot. (And recall, that it has little to do with the mass of everyday objects, as people sometimes say. That’s a different matter… everyday objects’ mass is dominated by their binding energy… coming from the forces that hold them together… not the Higgs mechanism.)
The first thing to say is “Congratulations!” to the winners. It is sad that Robert Brout (Englert’s co-author) passed away before he could get the prize as well. A nice thing you can do is take a look at the actual papers that are central to the citation in Physical Review Letters right here, as the APS have made them specially available. It’s good to take a look at what the actual papers look like, to get a sense for how our field works, so go ahead. I also recommend the lovely book of Frank Close, “The Infinity Puzzle” for a very good presentation of much of the ideas and history of this and related chapters in the field of particle physics.
My own thoughts on all of this are mostly of delight, but there’s something else there as well. Without a doubt, it is great to see particle physics and the pursuit of [...] Click to continue reading this post
I did an interview last week Tuesday with the channel CU@USC. It is a chat show, and so I did the sitting on the couch thing and so forth. All very amusing…
…And hopefully useful. I am spending many hours each day building awareness for this year’s USC Science Film Competition, an annual project you might remember me starting back in 2011, and stressing over a lot. And then again in 2012. It continues to survive for another year. This is year three, and although it has given me many grey hairs, I fight on, because I think it is of value to get students from all fields, whether scientist or engineer, writer or filmmaker, journalist or artist, to learn to collaborate in the art of telling a story that has science content. (Actually, learning to collaborate to tell a story about any issue of even moderate nuance is an important skill, science or not.) Anyway, the interview material is now up online and so you can have a look here. (The site uses flash, so might not work on some devices.)
I speak about the competition and also my own take on bringing science to film both fact and fiction (which for the latter especially is probably different from many others in that I don’t think it is always productive for a scientist in a film project to be [...] Click to continue reading this post
Fail Lab Episode 3 is up at Discovery’s Test Tube channel. This week talks about electricity a little bit, again in the context of an online fail video that we unpack a little. I say “we” since this time I’m on the show (accidentally showing off my energy-manipulating powers in public again – I really need to stop doing that).
It was a lot of fun to help out with the show that day, and (for better or worse!) there’s a bit more with me on the way, and of course lots more of the whole Fail Lab series to look forward to.

I find myself in New York for a few days. (Sorry for the gap in blogging this week!) The blurry picture summarizes one of my favourite things to immerse myself in when in the city. A great upstairs bar on the corner of 2nd street and avenue A, and a great band of young jazz players that gives one hope that the art is not dead.
My main business was earlier today, at a studio in Brooklyn, shooting some promo material for the new big documentary show on the History Channel (probably on H2) that will air later this Fall. I’m not sure if it is out there what the new show is so I will hold off until I know what I can tell you. Needless to say it involvs science, and I think it mixes science and other topics together in a nice way that makes for a nice concept for a show. More later, I hope. Here’s a shot with me in the middle of the setup*! Charmingly made up to give he impression of a star field, perhaps, when viewed through the A and B cameras: [...] Click to continue reading this post
By the way, I’ll be on the local TV show CU@USC tonight (6:30pm – live), talking about things like communicating science, science and film, and of course the USC Science Film Competition that I run that I’m trying to let students and faculty know about as much as I can. (Perhaps we’ll talk about other topics as well. We shall see.) I’ll also be joined by Simon Wilches-Castro, a student who was in the competition two years ago. He did the lovely animation for the film on fractals, called Yaddda Yadda Yada.

Interesting (and not surprising) decision over at the Popular Science website* concerning comments on articles. It’ll probably remind you a little bit of my post from a few days ago about the kinds of behaviour surrounding blog discussions of research in my field. At some point, especially for a complex subject and in times when people are not inclined to really dig deeply to learn the issues, it all can get very counterproductive.

Episode two of Fail Lab is up now! (I told you quite a bit about this new series on the Discovery web channel Test Tube last week.) This is another excellent quirky and fun one, talking about the dynamics of sexual selection that’s going in all those fail videos you see online, where the guys are making a pig’s ear of some trick or other. This week you get to see the show’s brain on display too!

Meanwhile, poor Matt Strassler, who means well, is re-discovering the frustratingly convenient (for some) fact that blogs (or is it blog readers?) have no memory for stuff that has scrolled off the page, so attention-seekers get to make the same deliberately wrong claims and misrepresentations they did before, and that were thoroughly addressed before, and a whole new bunch of people who want to learn a bit of science will be drawn in to a non-debate, not knowing that none of this is new. Attention-seekers get the attention they desire, and since attention is the main point for them (not actual progress in science, oh no, not at all!), they succeed.
Matt is discovering this now… By trying to discuss a little nuance about what recent discoveries at the LHC may or may not mean for string theory, he has wandered into the same old tired shouting match about string theory with attention seekers who have nothing better to do but put their hands over their ears and yell misleading slogans from the sidelines to generate fake controversy, and/or split the world into pro-string vs anti-string which is so simplistic and, frankly, juvenile. An interesting game, if you’re up for it, would be to look at the noise in the long comment stream there, and then look at almost any of my Scenes from a Storm in a Teacup posts (from 2006!!!) and the long comment streams accompanying them (look at, for example IV, V, and VI), and see if you can see the same sorts of patterns. I deliberately collected those posts together to form a partial* record of some of that time’s discussion for precisely this purpose, for those who care to read and see that all attention-seekers (who have no real interest in letting science research run its course) have to do is wait for a while and then start yelling the same faux claims all over again to get attention, sell books, enlarge their mutual admiration society membership, etc.
You know, all this behaviour is hardly different from that of the annoying squirrels I have to deal with at my fruit trees from time to time. Not being so good at cultivating [..] Click to continue reading this post
Because I love classic Queen, and because I work on string theory, but mainly because he did such a great job on everything (writing, production, puppets, singing…) I had to share this video with you, made by Tim Blais at a cappella Science:
(Embed is below…enjoy!)
So episode 1 of the new show I told you about, Fail Lab, is live!
And now I can tell you what it is about.
I think the core concept is a nice idea. You know all those “fail videos” that are so popular online? It’s all about laughing at people who’ve been filmed with something going wrong… they’ve been trying a trick that fails and they get hurt, or an accident happens, or something like that. Well, rather than just laugh about it and make fun of the people in the video, Tosh.0 style, the show is (in a fun, and yes, decidedly edgy, way) built around trying to find a bit of science in the fail video. In fact, the idea is that at the end of the segment, presenter Crystal Dilworth (a smart young scientist on the neuroscience PhD program at Caltech) discusses (and in some instances, argues) with the guest scientist presenter about whether the video is a success or a fail, and sometimes it is a success for showing science! Each week on Discovery’s new(ish) TestTube Channel (excellent name) there’ll be a new episode (Tuesdays around 9:00am) coming up, so stay tuned. Episode 1 is here.
It’s fun (with puppets, dancing, music, and a great eccentric set for the lab!), and will be definitely playing on the edge for some (perhaps too much for those who are skittish about mixing sexuality with science), but from what I’ve seen, the show looks to be on [...] Click to continue reading this post
Reportedly it’ll be “a new kind of science series”, so we shall see!
That’s all I know so far as regards the launch.
More when I know more.
By the way, it relates to this, and indeed that is Crystal Dilworth, the presenter, in the poster.
Er, the picture/poster is blatantly borrowed/stolen from writer/director Patrick Scott’s twitter feed.)
Last year I mentioned the fantastic work of Julien Bobroff and his collaborators in developing an impressive science outreach program that does wonderful demos of the physics of the quantum world, using superconductors (and other things). He gave a talk about it at the Aspen Center for Physics and took part in some discussions about outreach at a nearby conference that David Pines had organized. Well, he’s written an article about the program and it appears in this month’s Physics Today and it seems that you can get it for free if you go here. I strongly recommend it since it might give you some ideas about how you might go about explaining some of the science you do to people (if you’re a scientist) or it might excite you to learn more about the science if you are not already familiar with it. Maybe even a show featuring science that might be coming near you one day, and/or go to a science fair.
THe great thing about the article is that it is passing on lessons learned – sharing both good and bad news. One of the the frustrations for me about the whole science outreach effort that is done by so many of us is that we’re largely reinventing the wheel every time we decide to do something, and moreover it isn’t actually always the wheel. We’re trying stuff and we’re not measuring its effectiveness, and we’re not sharing much about what works and what does not, so the outreach effort goes only so far, largely. It is one of the reasons you read me writing a lot about trying to do different things beyond just the usual- putting science where you don’t always expect it, since most of what is done is picked up by people who are already predisposed to pay attention to the science, which does not expand the reach of the outreach very much. Julien picks up on an aspect of this issue nicely. Quoting [...] Click to continue reading this post
This is the last day before the new semester starts here at USC. I’ve been wandering around the house a bit slowly. One reason is probably the excellent dinner party last night, which involved a lot of cooking for a lot of Saturday. That went well, and people seemed to enjoy themselves a lot. Good reason for a slow day the day after. The other reason is that it is simply nice to enjoy the calm before the storm of the new semester begins in earnest… So slow wandering around the house doing various simple tasks seems about right.
At some point I decided to start looking for my materials for tomorrow’s class. I teach graduate level electromagnetism again this semester (part two of a two part course) and so it is a good time to start looking into old folders and so forth, trying to see what I’ll re-use, what I’ll re-do, and so forth. It seems that last Fall was the first time I did a complete scan of all my hand-written notes into pdfs to allow me to deliver them from my iPad, and so that’s good news right there. I can annotate right on top of those and add new pages if I want to… but it is nice to start with a base of good material to hand right at the starting gate.
While I’ve been looking through materials I’ve also been making bread. I’ll need some for the week, what with sandwiches and all that, and it is a also a pleasantly slow and endlessly rewarding thing to do. I decided to make a more moist final dough than I have in recent times. I think that this will give both a nicer crust and crumb. That blob in the bowl in the picture above left is the result of a very successful first rise. Most of bread making is waiting, and so it is perfect for when you are doing slightly mundane but time-consuming tasks like looking at old files of course notes.
I rolled everything out into 12 rolls and a good slicing sandwich loaf and put them to rise again and went back to tinkering with files (analogue and digital). The picture to the right shows the result of that second rise. The oven is being preheated and they are nearly ready to go in. Already the smell is great, even though right now it is just a yeasty-doughy smell.
I’ve been wondering whether to jump ship and abandon Jackson as the main text for the class (shock! horror! – Jackson is a staple of so many graduate courses in physics) and go with something new. There have been two texts of note (that I know of) in the last couple of years that have risen to challenge Jackson’s supremacy, the one by Anupam Garg (“Classical Electromagnetism in a Nutshell”, Princeton), and the one by Andrew Zangwill (“Modern Electrodynamics”, Cambridge). My feeling is that both these books (I’ve looked at Garg more than Zangwill [update: see later remarks]) do a good job of making the subject seem alive and modern. Jackson has a great deal of useful material, presented in a firmly sensible way that is hard to argue with, and it will always remain a classic, but sometimes I think it suffers a bit from feeling somewhat old. I like that, for example, there’s a nice treatment of the beam of a laser in Garg as an [...] Click to continue reading this post
For those who have a thirst for something physics-y to follow the tomato chutney post, here’s a decorated physics diagram I made in Matlab this morning. Click for a larger view. It’s the phase diagram of interesting black hole transitions* (that I co-discovered 14 years ago) associated with part of the story I mentioned last month. On the right of the line you have small black holes favoured (of a given charge, so move horizontally), and on the left side of the line the system favours large black holes and so when you cross the line you have a sudden jump from one type to the other. That second order critical point I talked about there is the end of the line of first order points. The blue dot. Above there, you cross over smoothly from small to large holes. The blue dot is the border between the two cases.
It is a bit like having steam (or water vapour) on the left and liquid water on the right, and crossing the line is what you call boiling. The second order point is the place [...] Click to continue reading this post
Yeah! It feels great when I get the workhorse computer really chugging along. 85% is unusual to see on a normal run, since this beast (a 2010 3.32 Ghz Mac pro quad core) has a lot of computational capacity that you don’t need for most tasks. I’m getting up to 85% because all four cores are crunching away independently on the same problem (written in MatLab) but different parts of it. Each point on the resulting graph will be the result of having computed 2000 points. Each of those 2000 points comes from computing a boundary value problem discretized into a million points. See an earlier post for more about that.
