Toggle Fun
I just have to say this. Any project that gives me an excuse to install good old fashioned toggle switches is going to be extra fun.

Red, Yellow, Blue, Green…
…among other colours.
View of the day from the garden. (Winter. Number x in a limited series of y.) (Click for larger view.) The rains have gone for a while. The sun is back, with clear blue skies to close out the year.
I’m trying to rest. Well, I’m working on various projects at home, mostly. Colours are on my mind a bit in one of these projects, actually. Later today I’m going to be down in the (only slightly mad-scientist) workshop making a portable screen on which to project films.
Projecting onto the wall is good, but I want to make a silver-grey screen with a dark border that will really pop the colours out. Some of this is about not projecting onto […] Click to continue reading this post
Tracking Santa
Ok, since it is two days until Christmas I suppose I can stop ignoring all the flashing lights and twinkly things and incessant “Holiday Music”. (Yeah, how time flies..!) I’ll even do a post discussing Santa. You see, it came to my attention that Google Earth, in collaboration with NORAD, no less, will be tracking Santa on Christmas Eve. See here and here for more details.
It sort of got my attention for the obvious reason -they’re tracking Santa!- but then when I went to browse the site, I thought I’d certainly point it out to you since on the further information for kids page (yes, in case you weren’t sure, it seems that children are a major target in this operation – check out the links to, er, fun things for them) there’s an “About Santa” page. Well, I had to click, since I’d certainly learn something. Indeed, I learned that some physics thinking has gone into pondering the Santa Phenomenon: […] Click to continue reading this post
Snowed Under
Ok. It’s official. This week I am snowed under with things. Every day I write half a blog post, and then something comes up and I do not got back to it and I fall into bed later, exhausted, some time in the wee hours, only to get up early the next day to carry on with things.
So in case you were wondering, I am still here. Just snowed under. I gave my final exam for my Physics 151 course (Fundamentals of Physics: Mechanics and Thermodynamics) on Monday (hurrah!) and I’ve spent a huge chunk of today playing with various excel files of various chunks of data from the course, trying to turns a sea of numbers into final grades for the students. It has been slow work, and I’m nowhere near done yet. It’s complicated because I must incorporate multiple components of assessment, from three different exams, laboratory work, online homework and written homework, to in-class responses using individual RF transmitters, and online quizzes of various sorts. (All a bit much, in my view, but, well that’s another story…) Every single bit has its own spreadsheet with data that must be uniformized and then combined to give the whole picture of each student’s performance.
It has made me a bit dizzy just talking about it.
But it’s not that simple. Oh no. Here’s a small part of the extra stuff: I’ve been trying to get the exterior of my house painted, and of course there have been (quite fantastic) rainstorms delaying everything and so I’ve been dealing with painters for longer than planned – with the Christmas holiday closing fast, and I’ve got my mum visiting me (hurrah!) and so I must be a good host and so forth and not just hide in the study crunching numbers (she arrived a day earlier than I expected – my fault! – so I’m a bit off-balance about that too), and… and…

Tales From The Industry XXVII – Light Speed
Here we go again! Tonight sees another new episode of the new series of The Universe on the History Channel (you can watch it as a warm up to The Atom Smashers, on PBS), and the episode is all about the speed of light! I’ve no idea how this one will turn out, but for my segments we did some rather fun things to illustrate some of the key concepts. The main idea is that the laws of physics are rather different from ordinary Newtonian/Galilean ones when you are moving at an appreciable fraction of the speed the light. This is what we learned from Einstein’s Special Relativity. How do you illustrate this for a TV viewing audience? Well, one way is to imagine what would happen if the speed of light was a lot closer to everyday speeds. Then you could illustrate some of the effects in a fun way.
Well, one thing led to another and somehow (after a lot of email discussions of the physics with Darryl Rehr, the writer/director) it ended up that I was supposed to do […] Click to continue reading this post
Asymptotia’s Type
Following Janet, I decided to check to see what my “blog personality type” was supposed to be according to Typealyzer. Apparently, it (and hence, I suppose, the person who writes it) is of type ISTP – The Mechanics:
The independent and problem-solving type. They are especially attuned to the demands of the moment are masters of responding to challenges that arise spontaneously. They generally prefer to think things out for themselves and often avoid inter-personal conflicts.
The Mechanics enjoy working together with other independent and highly skilled people and often like seek fun and action both in their work and personal life. They enjoy adventure and risk such as in driving race cars or working as policemen and firefighters.
Aw shucks. You flatterer, you. (Wow, and they even got my overalls and hairdo right too!)
Then there was some sort of fanciful brain diagram, showing where things are on the […] Click to continue reading this post
Tales From The Industry XXV – Parallel Universes
While most of the episodes of the History Channel’s The Universe series are firmly about scientific knowledge of the universe that has been tested and verified (from planetary science, to solar physics, to stellar evolution, and various topics in cosmology, and so forth), they also like to treat topics that have a higher component of more speculative material. This is of course fine, as long as it is made clear what is speculation, and what is established. Recall that I took part in a really fun episode called Cosmic Holes, which talked about white holes and wormholes -entirely speculative objects – right alongside the physics of black holes, objects that we know are physically realized in our universe. (See here, here, and here.) I think that Laura Verklan, the writer/director, did a really excellent job of separating out the speculative from the established. Similar things can be said for the episode Cosmic Apocalypse, done by writer/director Savas Georgalis (see here), which focused on scenarios about how the universe might end, given what we have already established about how it was in early times and how it is now.
I’m hoping that the upcoming (tonight!) episode entitled Parallel Universes will also be a nice and clear piece of work discussing the speculative ideas concerning the possibility of parallel universes – what the ideas are, why it is a fun idea, what it […] Click to continue reading this post
Apollo
I’ve been running around so much today I forgot to actually mention the event for which I’ll be acting as host tonight, here at USC. This is how I quickly described it to my colleagues, but bear in mind that it is open to all:
I’d like to remind you one last time about the Apollo Visions and Voices event today. Whether it interests you or not, please encourage your students to go. It is the College Dean’s V+V event for the semester, and was chosen to have a focus that would attract science and engineering students and faculty to sit with our friends and colleagues from the arts and humanities. It is at 7:30 pm in Bovard, with a reception at the end. I think that it will be very interesting and enjoyable.
Information about it is here.
It should be fun!

Hollywood Halloween
Hollywood Halloween. How about that…. two perfectly matched words side by side like that, and in context. Well… last night’s West Hollywood Halloween Carnaval confirmed my faith in Los Angeles (in the broader sense) as a city where people can indeed come together in vast numbers in if there’s enough will to do so. And boy do I mean vast. I’ve never seen this many people in good spirits in such […] Click to continue reading this post
Categorically Not! – Entanglement
The next Categorically Not! is on Sunday October 19th (tomorrow!). The Categorically Not! series of events that are held at the Santa Monica Art Studios, (with occasional exceptions). 
It’s a series – started and run by science writer K. C. Cole – of fun and informative conversations deliberately ignoring the traditional boundaries between art, science, humanities, and other subjects. I strongly encourage you to come to them if you’re in the area. Here is the website that describes past ones, and upcoming ones. See also the links at the end of the post for some announcements and descriptions (and even video) of previous events. (Image on left is of bubble master Stirling Johnson, in action during the September 14th 2008 event on Bubbles.)
The theme this month is Entanglement. Here’s the description from K C Cole: […] Click to continue reading this post
Tales From The Industry XXIV – Equation Wrangler
I’m sitting in one of my favourite cafes (Groundwork at Cahuenga) after a couple of hours work with some filmmakers. I’ve mentioned them to you before, you may recall. Eric Salat and Philip Shane are making what is gearing up to be a really fantastic documentary. I’m still not sure whether I’m supposed to talk about the content just yet, and so I won’t be to specific. As I mentioned before they are really trying to tell the science story in some depth. They’re illustrating the development of an idea, the wrong turns, the frustrations, the moments of elation, depression, and everything that goes into the process of doing the sort of work we do. And here, “everything” includes the confrontation of the ideas with the elation of seeing the success of a long struggle to understand Nature. I’ve spent some time chatting with Eric and Phil about the physics ideas, as have other scientists, and I have a good sense that they are so keen to tell the story well, and give the science and the scientific process a chance to shine – something that can often get neglected in some of these shows.
What was I doing today? […] Click to continue reading this post
Will Explain Physics For Food…?
It’s been super-busy here in my universe, coupled with turmoil of various sorts. This has kept me away from doing some of the sorts of posts I’ve wanted to do. I hope to tell you a bit about what I’ve been up to when I get a chance. I managed to squeeze in some time for a movie last night, and I’ll do a post on that shortly, since I thought it was wonderful. In the meantime, I thought that while I do a quick breakfast before diving into the day, I’d mention the following.
Alternative Title: A Physics Blind Date
A couple of weeks ago, I got an email out of the blue from a lawyer from out of town. He explained a bit about the type of law work he does, and then went on to say that this was nothing to do with what he was emailing me about. He was emailing me about physics. Turns out that in their spare time, he and his law partner spend time discussing and arguing about physics concepts such as General and Special Relativity, and Cosmology. They’d got to a point where they were confused about various details. The popular level books that they were reading did not really do it for them in terms of getting them past certain concepts and they thought that they’d just contact a physicist and ask.
Hence the email. He wondered if I’d be able to take some time to answer questions. He was terribly apologetic for bothering me, and knew that I might decline since I’m probably very busy.
Well, my response you can guess. […] Click to continue reading this post
Little Bang
Well, they aired it. Gosh. It’s a pared-down version of what we shot (there were three questions for The Big Bang Theory’s Jim Parsons in all… one asking him to explain the Big Bang Theory, the entropy one you see in the clip, and finally “Newton Vs Einstein – Who’s funnier?”), but amazingly they actually aired it on Monday in the […] Click to continue reading this post
Bubbles Galore!
There were three excellent presentations under the theme Bubbles at the most recent Categorically Not! at the Santa Monica Art Studios. See here. The final one was a visual treat which got everyone on their feet applauding at the end. It was Sterling Johnson, lawyer by day, bubble superhero by night, showing us some of his superpowers. I captured some clips of it, and edited them together for you. (Sorry about my laughing into the microphone at one point. I couldn’t help it.)
My two favourite moments are at 5:28 when he does his “Invisible Bubble Trick” -it is […] Click to continue reading this post
Tales From The Industry XXIII – Big Bang Theory
Thursday is my first day I can take a breath this week. The last few have been crazy and so I’ve not found time to edit that bubble video I promised, but it is coming. I hope I can get to it tomorrow.
Today is still full of stuff here and there, including a referee report, another report, some administrative things for my class, and then another attempt to think through a thorny puzzle on a research project. The class admin should have been done last night since Thursday and Friday are supposed to be free of undergraduate teaching issues, according to my agreement with myself. However, we had a seminar visitor – Rene Meyer – and so after my class ended at 7:00pm, instead of doing the administration I went to get a bus to downtown to meet with him and my student Arnab for dinner, at the excellent Blossom, one of my favourites down there. There was a bit of walking around to show them some of downtown’s lovely hidden treasures in the form of so many elegant buildings that are ignored by most. (Yes, people, there are restaurants and cafes and things open downtown at night. And of course bars. Go see.)
Now on to the other thing:
As a result of a phone call that came through while I was hosting Rene yesterday, it […] Click to continue reading this post
