We Interrupt This Broadcast…

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!

war of the worlds tripod illustrationThe 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

Pauli’s Other Principle

Do you know about Pauli’s Other Principle? One statement of it is:

Fermions are discovered in the US, whereas bosons are discovered in Europe.

(In case you don’t know, it is useful to classify particles according to whether they come with integer (0, 1,2,…) multiples of a basic unit of spin, or half-integer (1/2, 3/2,…) multiples. Fermions include the electron and the quarks, bosons include the photon and the gluons…)

Jester at Resonaances examines the striking evidence for the Principle in modern particle physics, and examines some of the predictions that follow from it. It was clear from the principle, for example, that the SSC (Superconducting Super-Collider) in Click to continue reading this post

Good Company

Brian May. Photo from: http://www.guitar-poll.com/BM.phpHey, guess who was at Griffith Observatory recently? Brian May! He’s that astrophysicist who took some time off to play (excellent) guitar and compose songs in the band called Queen. Ring any bells? (I found the nice photo here.) So why was he in town? Well, a slightly giggly (but always great) Madeline Brand (of the NPR program “Day To Day”) went along to interview him, and you can listen to the interview here, and read a transcript, as well as see extracts from him book (written with Patrick Moore and Chris Lintott), charmingly and blatantly (but knowingly?) unrealistically called “Bang! The Complete History of the Universe”. I actually looked through it in a bookstore the other day – looks rather nice. Wonderfully produced and I read some well-written passages, so might be worth picking up if you’re looking for a fresh read about the universe.

As a side note, I was a huge fan of his during my middle to late teenage years and Click to continue reading this post

Random Web Stuff, I – The Princes

Well, every now and again the link tracker from google’s blog search engine (which reports some links to the blog to me on the blog software’s control panel) throws up some weird random stuff. the princesThere was a funny one today. Some site that aggregates random stuff had a post about the Fresh Prince. It then gathered images from the web to illustrate, and somehow grabbed an image from this blog among the haul, which is why I knew of this. Two that ended up together are to the right.

Prince pictures, it said. Excellent.

Inside the LHC!

I recommend these videos that show the inside workings of the ATLAS detector of the Large Hadron Collider (LHC) using animation. They are quite stunning and simply lovely. Science aside for a moment (and you can learn about it in the posts listed below), remember that the LHC is simply the largest and most complicated device ever constructed, with the largest team of scientists assembled. It is a wonderful reminder of the international, collaborative, and cross-cultural nature of science.

So Have You Been There Yet?

I’ve mentioned it twice (here and here) in other posts, but I think it is worth a post of its own.

Have you been yet? I’m looking at you, USC-area person. There’s a fantastic new wine-bar in the neighbourhood, a relatively short walk north of campus at Union and Hoover. I’m so pleased to see it, and it is extremely welcome as far as I’m concerned. It is called Bacaro, and I’ve been there a lot already with several different groups of friends and colleagues.

Why? Well, the wine is just great (various Italian wines) and the menu is fantastic too Click to continue reading this post

Tired

It has been rather a tiring last several days. I’ve been focusing on writing a big report on various internal matters that my committee was charged to study for the whole academic year. The issues are rather large, and the solutions I was trying to present require not just cosmetic tinkering but major changes in the way things are done. So the key thing to get right in writing it is a tone that is critical of what there currently is in place while at the same time painting a picture of what could be in its stead, while also beginning to show how to get there. If you don’t balance all three just right, there’s no chance that anything will change, since either lots of people will just be pissed off that you trashed their system, or threatened the status quo, or they’ll agree but say there’s nothing that can be done, or they’ll say you have not really thought it through. I think I’ve managed to get the balance right.

It was due on Monday. On Sunday night, I had something down, but I did not really like Click to continue reading this post

Major Cyclone

Update: 11th May ’08. Well, as you probably know, estimates have surpassed 100,000. An urgent concern now is the additions to the death toll resulting from the lack of emergency relief, brought on by the restrictions placed by the Myanmar government. See a BBC report here, or an NPR report here, for example.

Update: 7th May ’08. It is much worse. I’ve seen a BBC report with a figure above 22,000.

The news is not good for Myanmar (Burma). The death toll due to cyclone Nargis has apparently passed 10,000 (see CNN and the BBC), making it the deadliest storm since 1999.

Sheril and Chris are blogging about it on the Intersection, (see e.g. here) and so keep Click to continue reading this post

JPL Open House!

Oh! It is the open house for the Jet Propulsion Laboratory this weekend (both today and tomorrow)! I almost missed it since it was two weekends later last year.

I went last year and had a great time and so I strongly recommend it. Go along for your own interest, of course, but if you have any kids, take ’em along*. If interested, have a look at my detailed post from last year entitled “JPL the new Disneyland?”

Oh Dear, I Liked Ken…

ken livingston on tube - from http://www.geocities.com/themole7/tuberules.htmlOh dear, I liked Ken. Now he’s gone from office. Ken Livingstone really understood public transport and did something about it. And the congestion charge…(which was my idea!!!*)… took someone with real guts to push it through. We need more people like him to fight the car lobby – to get people to change their behaviour and do something for their environment.

Thanks, Ken.

Sad Ending

sam smith’s oatmeal stoutThat’s it. The class is over… I have to admit that I’m pretty sad to see the end of it, although I’m very very tired. It was such a great group. (I’ll be toasting the end of it all with some of the splendid stuff to the right.)

Recall that we stepped away from black holes. After a look at cosmology for some lectures, where we understood the role of four crucial components in determining a universe’s properties (curvature, matter, radiation, and vacuum energy) we dove back into formalism for a short while (one lecture) to develop a little more the tools we needed to properly under stand how to formulate Einstein’s field equations.

It did not take long… You need only the idea that it makes sense to formulate everything in terms of objects that allow you to express the full sense of an equation in any coordinate system you care to write. Once that is done (the objects are called tensors, and the idea and how they work is pretty simple to get to grips with) the key to formulating the field equations of gravity is to have a look at the structure of other familiar systems. The field equations of electromagnetism (Maxwell’s equations) and the field equations for Newton’s formulation of gravity give the required clues. A rummage around the geometry to find the appropriate object to express the physics in terms of uncovers the Riemann tensor and its cousins (“contractions” to get Ricci and so forth), and you’re almost there.

Center For Inquiry: Chris Mooney on The War

Well, here’s a turn up for the books. I pass the buildings of the Center for Inquiry (West) in Hollywood quite regularly on my to-ings and fro-ings, and always wondered what it was. About what were they inquiring? My inquiring mind wanted to know, but by time I got back to a computer, I’d forgotten all about intending to Google it. I was sort of expecting that it might be some, er, fringe organization, given the neighbourhood (not 1/4 of a mile away is uncle charles - center for inquirythe mother ship (or one of them) for the Scientologists, and a similar distance in the other direction is the “Scientology Celebrity Centre” too, where John, Tom, Kirstie, and others from the remarkably large movie star Scientology set presumably go and hang out and feel… celebrated).

Well, it turns out that it’s not like that after all, but a place where, as far as I can tell, serious reason-based inquiry into issues surrounding the places where, e.g., science, religion, culture and superstition intersect (such as, you know, real life) is encouraged. I like that poster of theirs I found, for example (image to the right).

Phil at LHC

Do you listen to the CERN LHC podcasts? They can be good. Every now and again, there’s a visitor there, and Brian Cox interviews them on site at the Large Hadron Collider. (Search archives for LHC or see links to lots of posts on it below, such as this one.) The most recent visit is by Phil Plait, aka the Bad Astronomer. They chat together about various aspects of the science to be done at the (soon to be switched on!) LHC, research in basic science in general, the scare-mongering business about the black holes destroying the earth (see here and here), conspiracy theories, and – of course – Click to continue reading this post
