Lecture Thoughts

waveguide_plot._cropWaveguides are fun. I mean on the page, although I imagine that they are fun to play with as fully realized physical objects too. But I was talking about them in the context of teaching undergraduate electromagnetism, as I am doing on my class this semester. I tell the class after the second week of class or so that we’re essentially done, and can all head to the beach since by then we’ve completed the derivation of Maxwell’s equations, which describe fully all electromagnetic phenomena. The rest of the class is essentially a semester of picking various situations in which we deploy the equations and study particular solutions. Of course, they realize that there is reason to stay, since that’s really the heart of it – studying those various situations and appreciating the range of delights those equations can yield. Among the most fascinating and delightful of those, er, delights, is light. Electromagnetic waves in general, and we study them in a whole lot of situations, including nipping along unfettered in free space, in conducting materials […] Click to continue reading this post

Outcomes

Well, I am coming to the end of the week of hiding away in this undisclosed coastal town, and I can report that it was very good for me. I managed to get enough immersion to work hard on one of the stories for The Project, and this morning I read it through (I actually broke it into two stories) and turned out to be not too bad so far. Hurrah! Reading it next to the completed rough visuals really helps. I wish I’d had time to work on more stories, but that’s for another time. I’m just thankful to have had the time to have a good focus on one.

figures_20th_march_2013_smallWednesday I went back to that studio I visited on Monday as they were having another drop in and draw session and I felt it would be a nice end-of-long-work-day relaxation to go again. The model was actually rather excellent, and I wish my speed was a bit better to catch some of her faster 2 minute poses since she had a great […] Click to continue reading this post

Congratulations!

In other interesting announcements today, the great physicist Alexander Polyakov has been given the Fundamental Physics Prize. (See the announcement here.) There was a remarkable award ceremony in Geneva yesterday, hosted by Morgan Freeman, and with lots of Physicists and others celebrating great work in various areas of physics. Polyakov has been a key and brilliant leader in many areas of theoretical physics, and influenced so many ideas and techniques that have fed into the whole field, and so this is a well deserved recognition.

I must note that it is a bit sad (to say the least) to do a google search on the news about this prize and see so many articles with a lot of just plain stupid focussing on a big prize going to a “string theorist”, as though this is somehow negative or ironic, and also missing the fact that Polyakov’s contributions are so broad and far-reaching […] Click to continue reading this post

Known Unknowns Decreased a Bit

Well, the day is here. The Planck collaboration has announced a huge amount of results for the consumption of the scientific community and the media today. The Planck satellite looks with unprecedented precision at the very earliest radiation (“cosmic microwave background radiation”, CMB) from the universe when it was very young (a wee, cute 380,000 years old) and helps us deduce many things about what the universe was like then, and what it is like now. Here’s one of the representations of the universe using the new sky mapping Planck did (image courtesy ESA/Planck):

There’s a ton of data, and a raft of papers with analysis and conclusions. And there’s a very nice press release. I recommend looking at it. It is here, and the papers are here. The title of the press release is “Planck reveals an almost perfect Universe”, and some of the excitement is in the “almost” part. A number of anomalies that were hinted at by the previous explorer of the CMB, WMAP, seem to have been confirmed by Planck, and so there are some important things to be understood in order to figure out the origin of the anomalies (if they ultimately turn out to be real physics and not data artefacts). [Update: Andrew Jaffe has two nice posts I recommend. One on the science, and the other on the PR. Jester also has a nice post on the science from a particle physicist’s perspective.]

What is the title of my post referring to? Well, the refined measurements have allowed us to update some of the vital statistics of the universe. First, it is a bit older than previous measurements have indicated. The age is now measured as 13.82 billion years. (I’m already updating pages in the draft of my book…) Second, the proportion of ingredients […] Click to continue reading this post

Lunch and Work

Productive day yesterday, more or less. Yesterday’s lunch break (in my undisclosed coastal town) saw me take a pack lunch over to the beach, for a bit of reading while I sat in a change of scenery. I’d brought the bike, and so it was nice to be able to pack up some things I might need, like a beach towel, a portable seat (just in case…. I did not use it in the end…), my notebooks, and some reading materials on the ipad (I was reading a bit of Paradise Lost, in fact), and carry it in the bike basket. (Actually I did use the portable seat… but not for sitting. I used it as a stand for the camera that took the shot above right.)

What am I doing on The Project? I’m mapping out and editing one of the stories. It has turned into quite a long one with lots of complexity, relatively, speaking. This means that I need to be careful about designing the layout on the page, and actually try to get a good sense of how everything fits so that I pace things properly, and page things out in the right way. So I am thumbnailing carefully, going beyond simple thumbnails and doing a first pass rough of the page. It slows the writing down, but will save a lot of time later on. Also, when I turn myself back into the penciller/inker and come to draw all the pages carefully, my job will be much easier, and quicker, as I’ll have the directions in the written script and the page layout sketch to guide me. I’ll be able to focus more on being the artist and less the writer at that stage. See the right for a laid out page.

Actually, using the brushes application on the ipad has been very valuable for this. I’ve not used it much in recent times, and so it was fun to rediscover it. I’ve been using […] Click to continue reading this post

Retreating

Probably not really the appropriate use to mean “on retreat”, but it makes for an interesting title. Anyway, I’m on retreat for a week. As you may know, I am in the habit of disappearing for Spring Break, and I try to get away from it all (or most) and have some time to myself, and maybe also work on a project. You will recall that Death Valley is often a destination, but for what I wanted to do this Spring Break, my old haunt won’t work. So instead I am in a small town somewhere on the California coast. I’ve set up shop in a little condo I’ve rented, and I’m trying to get some writing done on The Project. I need to do a lot on the computer, putting together a lot of the material and scripting it out properly, which also involves planning and thumbnailing the pages. This is a slow process that needs lots of immersion, and I’ve not been able to do that this semester much… so this is why I’ve devoted the Spring Break to it. My routine so far has been to go for a short run on the beach first thing in the morning (not for long….I am not a runner really, and only like running on surfaces like grass, and sand that don’t hammer back too much, but it is exhilarating to do a short run in the morning and get all the juices flowing…) and then sit down to work over breakfast. But since this is really day 2, it is not clear if this is really a pattern or not.

This afternoon I sought out the local “drop in and draw” session to do a bit of life drawing from a model. Just as I’ve mentioned before (see two posts ago for example) you can often find such things in your local town, and it is not too hard in areas such as coastal California towns since there are lots of artists living in such places, and they seem to like and appreciate the value of life drawing practice. So I showed up, paid my money, and went into the studio and drew. The people were welcoming, did not pry too much into my business, and it was quite […] Click to continue reading this post

We have a Higgs!

So it’s very much worth noting that there are some new announcements from earlier this week concerning last years’ landmark discovery at the Large Hadron Collider. The news is that a Higgs particle was discovered. There were several news stories about it in the last few days. This might be a bit confusing, and many of you are thinking that this is recycling news from last year concerning the discovery of the Higgs. It is not recycling. If you go back and look at the results that were announced last year, there was an important note of caution, notable in the fact that the particle discovered was referred to as “Higgs-like”. More analysis was needed to be sure that it was indeed a particle that fits the name Higgs. Well, that analysis has been done, with more data included and so forth, and both experiments (CMS and ATLAS) are now sure that they are seeing a Higgs particle, and indeed it is one that is very close to what you’d expect for the Standard Model of particle physics.

The latter is is important and interesting to note, since many people expect that there […] Click to continue reading this post

Rusty

Well, yes, I’ve been very busy with several things. After clearing away a lot of them, I decided last night that it had been long enough since I’d visited a “drop in and draw” studio to practice figure drawing, and so I went along. (I’ve written about this on previous occasions…you drop in, pay a fee towards the model’s salary, and then you draw. You can find such studios in your own city if you wish. There’s nothing like live figure drawing for practicing observation, hand-eye coordination, and a host of other skills that need regular maintenance.)

Anyway, I dropped in, said hi, started up some Kate Bush (“The Sensual World”) on the ipod (followed by Mayte Martin – “Al Cantar a Manuel”) and I drew. A great and […] Click to continue reading this post

Another Quantum

So were you, back in 2008, among the many wondering what a Quantum of Solace was, and probably coming up blank? Did you eventually give up and put it out of your mind? Well, there’s another quandary at large that might trouble you for a while, and for the same reasons as before. Royal Caribbean International have launched the new name for their new oceanliner(s).

It is… wait for it… “Quantum of the Seas”. (I learned this from an ad break during the Oscars last weekend.) Now, the “of the Seas” bit continues a tradition of names over the […] Click to continue reading this post

Air Lines

Continuing my recent series of short trips around the country for various reasons means that I continue my series of that fun pastime and practice routine of flicking through the airline magazine and finding interesting people to draw (some recent ones are here and here). I did three this time, and here are a couple.

The first one was a quick warmup (I cleaned out some lines since it was on top of another drawing), and it turned out nicely although it looked not a lot like the actual […] Click to continue reading this post

Chicago

I find myself in a cold climate for a short while, once again serving on a committee that needs my in-person participation. It is snowing outside here in Chicago, and it is nice to look at the snow from the window, and occasionally pop from one building to another.

This allows me to pretend that as a Southern-California-softy I’ve had my annual dose of proper cold weather, with a real opportunity to wear a heavy coat and a thick jumper (sweater to those State-side) for at least one time this year. My hotel room is in a tower, and has a nice view out of the window. I tried to take a shot that captures the spirit of it. Pity I’m not able to enjoy it much, given […] Click to continue reading this post
