Different Teacup, Same Storm

By | | , , ,

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 →

Fail Lab

So episode 1 of the new show I told you about, Fail Lab, is live!

fail_lab_ep_1_still

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 →

Completed Seminar

institute_seminar__finished_smallWell, it is still in progress, as you can see from the picture, but my work on rendering it is completed, more or less. (One never stops tinkering at these things, but I’m going to move on.) This is the more refined version of the rough I showed you a couple of posts ago here. This panel is part of the opening splash page for this particular story of the graphic book project and so what you’re actually seeing is one of three tiny inserts on top of a larger establishing-shot kind of splash/bleed page. So the truth is that it’ll be so small on the page that almost nobody is likely to […] Click to continue reading this post →

fail_lab_poster Fail Lab is coming in five days.

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.)

Seminar in Progress

By | | , , , , ,

institute_seminar_smallI recently spent a bit of time (quite a bit of time) carefully reconstructing details of a certain Institute in Europe from memory (I visited some years ago) and some photos in order to set the opening scenes of one of the stories for the book project. (What sort of details? Things like what the layout of the rooms are, the style of the building, the number of radiators along the walls, types of windows and black boards, chairs, and so forth. I’m a tiny bit detail-oriented at times, you may have noticed.) I’ve been laying out the opening splash page and the inset panels have a seminar in progress. This was fun to draw. I started out with this view partially roughly constructed with pencil and then since it was small and fiddly, decided to pop it onto the ipad (legacy model) and finish and refine aspects of the drawing digitally.

I remain in two minds about sketching digitally like this. One the one hand, it does […] Click to continue reading this post →

Quantum Physics for Everyone

By | | , , , ,
1 Comment

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 →

Abacus Cadabacus! – Flash Anzan

sorobanI was quite stunned by this. For the first part, it is great (and charmingly bizarre) that there is a craze based around the abacus that has such a following (abacus or “soroban” championships), and for the second part… it is nothing short of remarkable when they get to the stage where they go “beyond the abacus”, and are just doing it in the head, but using abacus moves. And so fast!!! The radio program “Land of the Rising Sums” by Alex Bellos that I learned this from is here. There’s also a Guardian article here. It is all mostly about how numbers and arithmetic are taught in Japan. I think it is great that (from the people they interviewed) there’s a sheer love of calculation and of numbers and that there’s none of the lamentable “I’m not good at this I’m a languages/sports/art person” attitude that is so common in our society and which is responsible for poisoning children’s education so early on. I also love that the abacus is so fundamentally old-fashioned – […] Click to continue reading this post →

Sunday Preparations…

By | | , , ,

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.

sunday_bread_1At 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.

sunday_bread_2I 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 →

Phase Diagram

Comments Off on Phase Diagram

phase_diagramFor 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 →

Steamin’

CPU_usageYeah! 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.

(Update: Now running even more tasks associated with this problem: Up to 96% now:
CPU_usage_2
…with nothing idle at all. This is probably not as efficient any more, but it is for a few hours and then back to 85%. In the meantime, it is amusing how it makes me feel I’m doing more work somehow…)

I assigned different parts of the graph to different processes by hand, not using a […] Click to continue reading this post →

Tales from the Industry XXXX – Comedy Moments and More

crystal_D_and_cvjWhat happened here? Who is that, and what exactly made her so annoyed? Read on!

There are a number of new things coming out on screens near you (or may have already aired) that might interest you. For fans of the History Channel’s The Universe (thanks so much for all the emails with kind remarks, and so forth, by the way) there’s a new show in the works that’ll mix science and history (and other disciplines) in an interesting way. I’ve no idea when it is set to air though, and frankly I’m very confused as to what is on History and what is on H2, the companion channel, so I’ll just say watch out for that. We shot a lot of material for that earlier this year, and I hope you enjoy the show overall, despite my mumbling mug appearing on your screen a bit!

Apparently the many of the Weather Channel’s science-y segments were shown, in a series called “Deadly Space Weather”, which imagines what would happen on earth if you brought various prevailing conditions on other planets back here. Yeah, I know… but actually it’s a good opportunity to think about science ideas, at least in principle. You’ll recall that I did some demos for that which were rather fun – and hopefully interesting too. I saw a piece of one of them online (10:44 or so), and got rather annoyed at one point. There’s a segment where I demonstrate – with real sulphuric acid – the effect it has on organic compounds, using sugar. It is quite spectacular. And of course quite dangerous, so I’m actually wearing a lab coat (yes, there are occasions where real […] Click to continue reading this post →

Franklin Vs Watson and Crick

By | | , , , , , , ,

Wow! This is exactly the kind of thing I’ve been hoping to see more of! When the report on this started on NPR about having students do music and video about science topics, I groaned a bit (while making breakfast) when I heard the Watson and Crick mentions in the clip in the background, saying to myself that it is so unfair that once again, Rosalind Franklin is being forgotten and a whole bunch of kids will miss the opportunity to learn about the nuances involved in doing science, and miss that she did such crucial work on this most important discovery…. I continued making my coffee, listening to the report with half an ear…. and then! …more of the clip was played and a girl’s voice came on, singing a bit about Rosalind Franklin, and then I realized that this was exactly the story they were telling in the video*. The whole NPR report, by Adam Cole, is here, with a short video doc. It is about not just the Rap B.A.T.T.L.E.S. doing songs and videos about various science topics, but also about other programs as well, started by people such as Christopher Emdin at Columbia, and others. Excellent.

I’ve embedded the Franklin/Watson/Crick video below. It was made by students in the Bay area, guided by Tom McFadden at Stanford. I think this is great piece of work since they did a great job on production, particularly with casting and costuming everyone to play the principals, cutting in reaction shots and so forth… It’s a real film! And for a change, for a popular rap about science that a wide variety of young people might be attracted to, this time the music is actual contemporary rap (which usually means well thought out lyrics combined with rhythmic devices that are definitely post 1980s, and not just a bunch of lines recited over a corny background beat – see another excellent example at the end of this post) which is great!

Science Slams!

Comments Off on Science Slams!

One of the things that came up in conversation in my meeting at the APS on Tuesday was Science Slams. These are a lot of fun, and are growing in popularity and frequency. Maybe you might want to take part in one, or organize one. There’s a lot of great theater to be had, and its fun for wider audience, just as poetry slams when done well can be fun for an audience that might not have chosen to study or listen to poetry. (See earlier posts on the local Dead Poets’ Slam, for example.)

My friend Herbi Dreiner, at the University of Bonn in Germany, (he’s in the photo at the right, used with permission) is one of the most active and experienced people I know of in the area of successfully combining physics, theatre, and (if you like) performance art. If you don’t know about his herbi_dreiner_slamminphysics show, that has even gone on tour internationally, have a look at an article he wrote about it (with links to video and photos) for the journal The Physics Teacher here (arxiv version here).

Herbi’s been getting involved in physics slams too, and he wrote a very nice piece about his own participation in the Guardian. Have a look here. He went into some nice detail about how (with the help of the audience) he illustrated the issues [..] Click to continue reading this post →
