As a reminder, today I’ll be at the natural history museum (LA) as part of the “Night of Ideas” event! I’ll have a number of physics demos with me and will be at a booth/table (in the Black Market of Ideas section) talking about physics ideas underlying our energy future as a species. I’ll sign some books too! Come along!

Many years ago, even before the ground was broken on phase one of the Expo line and arguments were continuing about whether it would ever happen, I started saying that I was looking forward to the days when I could put my pen down, step out of my office, get on the train a minute away, and take it all the way to the beach and finish my computation there. Well, Friday, the first such day arrived. Phase two of the Expo line is now complete and has opened to the public, with newly finished stations from Culver City through Santa Monica. It joins the already running (since April 2012) Expo phase one, which I’ve been using every day to get to campus after changing from the Red line (connecting downtown).
On Friday I happened to accidentally catch the first Expo Line train heading all the way out to Santa Monica! (I mean the first one for the plebs – there had been a celebratory one earlier with the mayor and so forth, I was told). I was not planning to do so and was just doing my routine trip to campus, thinking I’d try the new leg out later (as I did when phase one opened – see here). But there was a cheer when the train pulled up at Metro/7th downtown and the voice over the overhead speakers […] Click to continue reading this post
Saving the world with better washing of dishes!?
Actually, every little bit of water-saving helps! Here’s a comedic* take on the small things we can all do that can collectively add up to a big help:

More adventures in communicating the awesomeness of physics! Yesterday I spent a gruelling seven hours in the sun talking about the development of various ideas in physics over the centuries for a new show (to air next year) on PBS. Interestingly, we did all of this at a spot that, in less dry times, would have been underwater. It was up at lake Piru, which, due to the drought, is far below capacity. You can see this by going to google maps, looking at the representation of its shape on the map, and then clicking the satellite picture overlay to see the much changed (and reduced) shape in recent times.
There’s an impressive dam at one end of the lake/reservoir, and I will admit that I did not resist the temptation to pull over, look at a nice view of it from the road on the way home, and say out loud “daaayuum”. An offering to the god Pun, you see.
Turns out that there’s a wide range of wildlife, large and small, trudging around on the […] Click to continue reading this post
Meanwhile, here at the Aviary (as we’re calling the garden because of the ridiculously high level of bird activity there has been in the last few months) there has been some interesting news. Happy news, some would say. This is hard for me since it is all about my arch-nemesis (or one of them) the Mockingbird. Many hours of sleep have been damaged because of them (they do their spectacular vocal antics during both night and day – loudly), and there seems to be more and more of them each year. I’ve been known to go outside (in various stages of undress) in the wee hours of the morning and thrash long sticks at parts of trees to chase persistent offenders away.
Well, we’d noticed that a particular spot in a hedge was being visited regularly some weeks back, and guessed that there might be a nest in there. Then one day last week, two juvenile mockingbirds emerged, practicing their flying! I knew immediately what they were since they have the same markings, but their feathers still have those fluffy/downy clumpiness in places, and of course they were not nearly as acrobatic as their adult counterparts. They hung out on […] Click to continue reading this post
On Friday the Los Angeles Institute for the Humanities went on another field trip. This time we went to the Natural History Museum. (Click the image for a larger panorama from one of the dinosaur halls.) If you’ve not been there for a while, this is not the museum you remember. It has been transformed, under the leadership of Jane Pisano (President and Director of the Museum, who gave us a splendid talk over lunch), adding several new spaces, a special garden, and new foci in its programming (such as special displays and research programs highlighting urban ecosystems – featuring coyotes, rats, squirrels, possums, Cooper’s hawks, doves, skunks, parrots, etc., (basically my back garden on a typical day, as you know from this blog), along with snakes, bedbugs, termites… The Nature all around us in the city of Los Angeles – fascinating actually.)
We had a tour of some of the spaces, breaking up into two groups (there were around 40 of us) and taking turns on two mini-tours (as we did for the Clark Library in December), one looking at the new dinosaur halls, the other the space dedicated to the urban environments I mentioned above. We learned a lot from our guides about what’s going on in the forefront of research in both […] Click to continue reading this post
The Nobel Prize in Physics this year is to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, for the blue LED. Seems like a small thing, but it is hugely important for a lot of reasons, not the least of which is the issue of producing energy efficient light sources for everyday use. We’re all benefitting from this recent discovery (how to actually make them!) already.
See the Nobel Press release here, and Congratulations to the winners!
There is a CicLAvia tomorrow*! I’m out of town right now (see next post) but I hope to make it back in time to enable me to go along at least for a little while. It looks like a fun route (see snap of map to left; click to enlarge), although it will be quite hot, so if you go, take it easy. The website is here, and you can find more information (like the 9-4 time) and so forth.
Enjoy!

Some rather exciting looking rainclouds, and a strong wind! Will we get some decent rain? Something like a biblical downpour, as promised by these clouds?
[Later:] A few spits of rain, but really nothing. Then back to sunshine again, disappointingly. We need some rain here in Los Angeles! Desperately.
To make the point more clearly, have a look at the site Climatestations.com for data on how we’re doing for rain as compared to the seasonal average. It is very disturbing.

I’ve a few things to tell you about from events over the last couple of days, and I want to mention some exciting events to come, but right now I must get on my bike again and head off up the hill in the park to the Griffith Observatory for an early morning meeting. As I was up again before the sun, I got to look out the window and see a wonderful – and rapidly changing – unfolding of the day. Thought I’d share it again*. Quite spectacular!

Up before the sunrise again this morning. Thought I’d share this slightly more abstract framing of the sun’s emergence with you, in contrast to an earlier post.
We’ve been having a virtual Summer here, almost consistently through the Winter. Very odd. One of the consequences is pictured. There’s a huge brush fire burning in Glendora right now, over in the foothills of the San Gabriels. I woke up to a lovely sky, and then noticed the strangest looking cloud in one part of it. Then I realised it was not a cloud. So I went on to the roof to capture a bit of the scene for you. I thought it would serve as a contrast to the photo from a few days ago.

Staying on the weather/climate theme a little bit, I should mention that we’ve been having some rather splendid sunrises these last few days. Spectacular colour combinations are run through in a matter of minutes as the sun emerges. I captured this image two days ago, stopping down a bit to get the cloud colours right, silhouetting a palm tree in the foreground to give a bit of context (also cropping some of the bottom off for better balance). Within a few minutes of taking this all the red had gone, pushing rapidly through yellow to white as the bright sun emerged.
By contrast, this morning was all billowing fog. The resulting visual range was […] Click to continue reading this post
I liked the piece on Morning Edition this morning about the experiments people were doing with the extreme cold in parts of the country, including making clouds, and seeing what happens to soap bubbles when they freeze!
The piece is here, and the “storify” box with some photos and videos is here. (The photo to the right -of frozen soap bubbles!- is by Beth Gilmore and I found it there.)
Today’s CicLAVia was, in my opinion, almost perfect. It was always my dream for it (long before it actually got off the ground) to be an event that closed all of Wilshire from Downtown to the beach, to allow the city to celebrate car-free-ness on a regular basis. For me, having Wilshire be the route would make it a core location that meant the city was serious about the event, would mean a lot of participation linking East and West, and perhaps most importantly, would give a lot of room, since Wilshire is a really wide street. Perhaps that it is a long way off to have the whole of Wilshire be used, but they came close to the dream by having a Wilshire one today. The route ran from where Wilshire starts (at Grand) all the way out to LACMA at museum square at Wilshire and Fairfax. I rode it with a friend in the middle of the day and it was a lot of fun. See below for some of the things we did. Also, watch the timelapse video I made (embedded later) which has some fun stills embedded in it as well.
You might recall some of the things that I felt the need to mention concerned me after the last CicLAVia. In that post I was most concerned about the narrowness of the route (they only used half of Venice for much of the way) and the fact that the resulting compressed group of people got even more compressed with the numerous traffic stops that there were. It was unpleasant and possibly dangerous. Well, there was not a hint of that here. They had both sides of Wilshire open, and relatively few traffic stops. This meant a lovely free flow of traffic for people of all speeds, ages, and mode of transport. The other main concern I had was that the event did not leave enough time for people to explore the route, leaving a number of people stranded, which is not good for a lot of people who are infrequent riders – they’ve got to get home cycling in traffic that they might not be ready to do yet. Well, today they extended the time by two hours, making it run from 9:00am to 4:00pm. Brilliant. I suspect that helped also with the potential congestion since people participating get spread out over a longer time.
Overall, I must congratulate the organizers for a nearly perfect event. Now if only we can have Wilshire open all the way to the beach for a CicLAVia, I’d be in heaven.
(Actually, just a few weeks ago I did my own all-Wilshire CicLAVia when I was heading to a couple of events at Westwood and Santa Monica. I started out planning to take my bike on the 720 bus but ended up giving up on the whole thing – there was a dreadful 45 minute hole in the schedule that made me horribly late for the first event and too many pushy people fighting to get on when the bus did show up – so I just cycled the whole way. It was a lot of fun, and helped me let off steam…but I’d love to participate in a whole group of LA residents doing it one day…)
So it was great. Having started Downtown and enjoyed the ride West, my companion and I […] Click to continue reading this post
