(Well, in the Ion Micrograph category, you understand.)
Sometimes extreme geekery is charming. (As you may know, I do not use the word “geek” lightly.) I spotted this on Phil’s Bad Astronomy Blog. You know what shape it is trying to evoke, I presume. Know also that this structure is 8.8 micro meters across, and that the subject was magnified some 5000 times normal size to make the image. I’ve no idea how they […] Click to continue reading this post
Happy New Year, dear Reader!
Forgive me for starting the year with an article on environmental problems, but it was Isaac Asimov’s birthday (at least the official one) on Saturday (I learned that here), and I found an excellent video of him talking wonderfully about global warming, united world action on such matters, and other issues back in 1988. It is below. I read a ton of Asimov back when I was a teenager. While not the greatest writing in a literary sense, it was full of wonderful ideas and compelling stories, and was quite inspiring for me at the time.
It is a pity that it was yesterday I switched on the little robot I use weekly to help me fight the good fight against dusty floors (see above right; the company that makes them is called iRobot, by the way – hardly any doubt that an Asimov reader was […] Click to continue reading this post
I’ve been wondering why over the last day or two I’ve been getting email about various apocalyptic scenarios. I’ve now figured out why, I think. On Tuesday, several scientists, myself included, played with the idea of how to destroy the earth! Well, it was on the History Channel in an episode of the show the Universe, (it was recorded back in June and July) entitled “Ten Ways to Destroy the Earth”. Of course, these are not scenarios we envision happening any time soon, but rather an excuse to talk about various kinds of science (from spontaneous symmetry breaking and the early universe, through planetary science, solar physics, and of course black holes and more). We list various favourite ways that were chosen to be discussed, and each physicist (although they called me an astrophysicist) picks a favourite. Fun stuff.
I chose putting a huge amount of antimatter at the core of the earth and letting it […] Click to continue reading this post
Forgot to report on this email exchange from last semester:
From one of the staff in the physics office:
Subject: 499 Syllabus
Date: Thu, 09 Jul 2009 14:01:38 -0700
To: Clifford V. Johnson
I was reading the syllabus you sent over for the 499 class. I am not sure if this is a type-o but in the Extra Books section it reads “/Black *_hoes_* and Time Warps: Einstein’s outrageous Legacy/” should it read
“/Black *_holes_* and Time Warps: Einstein’s outrageous Legacy/”.

I’m sitting here recovering from last night’s event (more later), which, when you clear away the details (and the large amount of left over food, huge number of dirty dishes, glasses, pots, pans, etc.), was all about science, filmmaking and the media. There’s something else that is being discussed a lot recently that is about that too.
It seems to be all over the blogosphere (e.g., here), since apparently Lost is a very popular show, and so I’ll mention it here. You can now enroll in Lost University as part of the DVD/Blueray release of Lost’s Season 5. What you’ll be able to do (it says on their website), is enroll and take courses in Psychology, Foreign Language, Jungle Survival, Philosophy, History, and Physics. The Physics part is all about time travel. Classes are being “taught” by real professors. I mean actual people, not characters. I know this since I’m one of these professors.
Who knew I’d end up being faculty at another university teaching such a popular […] Click to continue reading this post
So, apparently there is physics in the upcoming huge film Angels and Demons (and presumably the book). Lots of it. I did not know that until recently. So imagine my surprise a few months ago when I got a message from a producer (Natalie Artin of Prometheus Pictures) of a documentary about it, asking if I’d like to contribute, talking about aspects of the physics.
They wanted me to talk about anti-matter. This is as a result of finding a blog post of mine over on Correlations, entitled “Not Science Fiction”, which starts:
Anti-matter. Seeing the previous word, you immediately glance back at the title, right? Strangely, it has been 80 years since the discovery of anti-matter, and we use it routinely in our technology. Nevertheless, anti-matter is still thought of as something from science fiction (and mostly bad science fiction at that).
It all goes back to one of my favourite theoretical physicists, Paul Dirac, and you might like how he found it (roughly). He essentially did it by […]
I agreed to talk, if I could focus on one of the main issues of my post: That anti-matter is not weird stuff of science fiction, but actual routine science…. so routine that it is used commonly in medical diagnosis, for example. The “P” in PET scans stands for “positron”. The positron is the anti-electron. (The “E” does not […] Click to continue reading this post
Now I’d see this version of Alien Vs Predator:

Well, I probably am not worthy of the press credentials I was carrying around with me on Wednesday, as several days later I had still not done my “report” on the event. Well, here it is.
I went to a press conference and a symposium that relates directly to the issues I was talking about in my Tuesday post and its comment stream. All the things I was talking about with regards better contact between the science community and the filmmaking community so as to make films (and shows) that better represent science and scientists more accurately through something closer to a collaborative mode were brought up in these meetings and discussions. It was great to see this issue being taken seriously, and a well-meant effort being made. The core of the idea is to set up an office that will coordinate things – acting as a sort of clearing house that will put filmmakers (of all aspects of the process whether screenwriter or director) in touch with willing scientists who can be helpful in various topics. This is the Science and Entertainment Exchange.
A key thing that I have mentioned here many times before is the issue of it being about more than just fact-checking near-completed work. If scientists are involved at […] Click to continue reading this post
I got this cute postcard from the people at Workaholic Productions. (Click for larger view.) You may recall a post I did some time ago about some things I was doing in a demo lab here at USC for a pilot for a new TV show. (Or, you may not. That’s what the archive is for – browse several of the Tales From The Industry” series here.) At the time I did not tell you about the show in detail, since I don’t like to reveal details of show ideas and so forth when things are still in development.
Anyway, the show is done. It’s a pilot, and so with your support, they may well get the go ahead to make more. So if you’re inclined, go and have a look. What is it about? Well, the idea is to start off with some standard (pulp) sci-fi scenario (alien invasion in this case) that you might see in a movie or tv show, and then through the course of the show examine aspects of what you see to investigate the science behind it. They have actual scientists (and engineers, since a lot of can be really about technology) come on and discuss things, explain science, do demonstrations, and so on and so forth.
This particular show, the pilot, has a lot of the standard alien invasion combat weaponry on display – shooting of ray guns, casting of lightning-bolt-like bursts of […] Click to continue reading this post
Sorry. Didn’t mean to cry wolf, but I always think of that great (as in camp and amusing) ending scene when I think of The Fly. The movie, anyway. (That’s in the original 1958 movie version – clip at bottom of this post.) Now there’s an opera! I am not joking. David Cronenberg has teamed with composer Howard Shore to create an opera. (You know the work of both of them rather well, actually, from film work together, and separately – Shore did the wonderful music for films such as The Lord of the Rings trilogy, and Cronenberg the film director needs no introduction.) I love the play on Da Vinci’s iconic drawing for the production’s publicity and so forth. See above right.
The artists are of the opinion (and I agree, in principle) that the themes visited in the story are powerful and resonant enough for an opera. Science, science ethics, new technology, fear of same, mercy killing… and presumably devotion to a cause, […] Click to continue reading this post
I love “do-overs”. Not because I want to change anything in particular about my life, but because they are so rare, and so interesting. On my way to Vancouver on Monday, I got to do one.
We (myself and the other passengers) boarded our flight at Denver. I usually get on the plane early, and so have the change to watch people go through their routines of boarding and all that entails. After that was all, the plane full of passengers waited for the plane to get ready, doors to close, and so forth. It did not happen. After a while, the pilot came on and explained that they were trying to fix the radio, and it would be another half an hour. So we waited. After another long while, the pilot came on and said that they did not expect that the radio would get fixed in a timely manner after all, and so they were going to try something else. We would “de-plane” (a word I hate by the way – what is wrong with the perfectly good word “disembark”?) and all make our way to another gate where eventually another plane would arrive, and we’d take that one. It would be exactly the same type of plane. We would keep our ticket stubs and just re-board an hour and a half later.
I wandered for a bit, found something not too repulsive to nibble on (seems to get harder and harder in some airports), was disappointed by the meagre bookstore once again, and otherwise killed some time. Then the boarding started again. A “do-over”. Everybody would be going back to the same seats, it would be exactly the […] Click to continue reading this post
I spent an awful lot of time as a child and teenager tinkering with various projects. I’d have lots of projects on at any one time, brewing in my head for a while, and making their way to notebooks and scraps of paper, then to elaborate drawings showing the technical details, and ultimately to some sort of realization in the real work, some percentage of the time. In the Summer time, I would probably have one Big Project and that would occupy my thoughts for a great deal of time, and would involve a lot of hiding away doing things. Lots of these projects would involve electronics (increasingly as time went by and I Learned more and my various part time jobs could support more) and there’d be lots of tinkering with all sorts of items, and a constant feature would be the soldering iron, one not so different from the one that you see to the right.
Well, one of the many things I liked about the Iron Man movie (yes, I was right there to […] Click to continue reading this post
One of my favourite topics to think about, since I was very young, is the effect that direct contact with intelligent alien life would have on our society. It would be transformative, I think, whether it be initially seen as for good or ill. Of course, most imaginings of such an event usually considers the “ill” aspect. I was chatting about the issue recently with a friend of mine while hiking the other day and then I recalled that I forgot to do a blog post on last week’s Sunday night radio listening, part of which was about just this very topic!
The show was in two parts (both good… more on the second later) and the first was a 1994 recreation of the classic War of the Worlds broadcast of 1938. You know the one, I hope… It was a CBS radio broadcast by the Mercury Theater company, masterminded and led by Orson Welles, and was a Howard Koch radio adaptation of the 1898 H. G. Wells novel. As you may know, the radio show created a huge panic among the listening audiences at the time, brought on by a combination of the relative newness of the medium (it was done in the style of a series of on-the-scene breathless news reports) and the general atmosphere in world politics at the time. (There’s a rather good Wikipedia collection of information about it here.)
All of this puts me in a nostalgic mood, since during some of my school days I loved that War of the Worlds rock musical concept album by Jeff Wayne from 1978 (I knew of it only in the early to middle 80s), with a star-studded cast of musicians (Justin Hayward, Phil Lynott, Julie Covington, David Essex and Chris Thompson), and the wonderful voice of Richard Burton as the main protagonist (a journalist). Anybody else remember that? From so many listenings to it, I used to be able to sing along to every note and word of that album! Probably still can, even though I’ve not heard it in so long. Altogether now – Uuuu-Laaaa!!!, or Come on Thun-der-child!!… Here’s a Wikipedia link.
Anyway, I highly recommend the recreation of the broadcast. Find an hour and curl up next to your computer and pretend it’s a warm old valve radio. Leonard Nimoy plays […] Click to continue reading this post
Tomorrow I’m shooting all day for a TV show that is going to focus on the idea of alternative universes (or parallel universes, if you prefer). Should be fun. The setting at least will be interesting (more on that later) and it ought to be interesting to see how the writer puts all the material together into a coherent narrative. Part of my job will be to try to emphasize that while parallel/alternative universes show up a lot in actual scientific discussions (and have done for a long time), we have not yet had anything like a good observational or experimental reason to believe in their existence anywhere other than in our imaginations. It’s vital to get this across (I hope they don’t just edit it out) because people are so willing to believe in many half-baked fanciful ideas – and this is one of them – and when they show up in a science documentary (this is (again) for the History Channel’s “The Universe” series, which has been very good) with actual scientists being quoted, one should be especially careful (as we were on the “Cosmic Holes” episode (with different filmmakers), which has proven to be rather popular, and is full of speculative ideas like travel using wormholes and time machines right alongside equally fantastic-sounding things, like black holes, which are in fact a scientific reality). The rest of my job will be to talk about some of the places where the idea shows up in modern thought, some of the reasons why, and some of the opportunities for solving various challenging problems (and maybe creating a host of others!!) can be afforded by such ideas.
All that aside, this reminds me of something else entirely – Do you ever have those days when you feel like you’ve accidentally stepped sideways into an alternative universe? I do. Recently, I had a huge dose of it. Sit back and I’ll tell you the story…[…] Click to continue reading this post
A silly lawsuit vs the search for physical law, that is. What’s the story?* An attempt to stop the Large Hadron Collider (LHC) in Geneva from operating over fears that the experiment will destroy the earth by creating a black hole that will swallow it up. Or some other bogeyman. Article by Dennis Overbye here, or here, and there’s a Fox News story by Paul Wagenseilhere.
The lawsuit, filed March 21 in Federal District Court, in Honolulu, seeks a temporary restraining order prohibiting CERN from proceeding with the accelerator until it has produced a safety report and an environmental assessment. It names the federal Department of Energy, the Fermi National Accelerator Laboratory, the National Science Foundation and CERN as defendants.
Quite an entertaining read can also be found at the two plaintiffs’ website. The main […] Click to continue reading this post
