Catch a Falling Star

Ok… A dying star. Here’s the before and after shot (images from the NASA Swift team):

supernovae 2007uy and 2008d

An the amazing thing is that they were able to watch and record the events in real time! The galaxy hosting the explosion was already under study because of an earlier supernova. This is wonderful, of course, and a big deal is made in various news articles about how great it is that this is the first time that a supernovae event was caught in real time from an earlier hint from an X-ray emission signature… Except that it seems that it isn’t!!! I do find it a tad annoying/puzzling that in a few seconds I was able to find pretty much the same sort of news announcement from two years ago. Does the press think that the members of general public are stupid, or have no memory? (I don’t yet have time to re-read both articles carefully, so I imagine this is maybe much better (it is rather closer), and there were more telescopes recording, and maybe from earlier, in a wider spectrum, and so forth, but not to mention the earlier event at all, as though a big news story was not made of it back then, is strange. (Perhaps the finding was discredited?) I did a blog post mentioning it entitled “When Stars Go Bang”, and you can link from there to a BBC news article for example of the coverage.)

Anyway, back to the excitement. We must not take away from the joy of discovery: From […] Click to continue reading this post →

cracks in ground (drying mud) at Death ValleyOh boy. Not what I really want to read just before going to bed. I’m likely to have dreams of falling into giant cracks* that open up under you no matter where you run. Did you have those when you were a child? I did. That one, and a slightly different version that involved a volcano, where….

Oh, wait. Back to the point. A report has come out with carefully researched projections from geophysicists and […] Click to continue reading this post →

Mountain Astronomy Party!

Mount Wilson 60 inch telescopeI was at an unusual and splendid event on Saturday. My friend and colleague, the writer Aimee Bender, organized a group of 25 of us to go to the top of Mount Wilson and spend the evening, mostly sitting in the dark, right up to well after midnight! What were we doing? Astronomy. We had the Mount Wilson Observatory’s 60 inch telescope entirely at our disposal!! This is not any old 60 inch telescope – it is one of the historic telescopes that’s up there, used since the early part of the 20th Century to discover things about our galaxy and beyond. (See also a post I did about the 100 inch, and the hike you can do up the mountain to see the site. [Update: Note – For this trip, we drove up, carpooling!])

Shelley giving information during the Mount Wilson observing sessionAimee had reserved the space well in advance, and we had a guide and a telescope operator (the excellent Shelley Bonus and Arbi Karapetian, respectively), and we brought food, which was spread out on a large table alongside vats of coffee and hot water supplied by the observatory.

This is an excellent way to spend an evening. Shelley is informative and enthusiastic, and does a great job of selecting various objects to be viewed (she also takes requests!) and giving lots of information and anecdotes about them, and much else besides. Arbi was also a gold mine of information.

The party was of 24 non-scientists (there were a lot of writers of various types, for example – poets, screenwriters, novellists, experts in poetry and literature and language…) and one physicist. As the latter, I tried to remain undercover, so as not to […] Click to continue reading this post →

Communion

Today I was at a Catholic church, attending the First Communion of the daughter of some friends and colleagues. This was a bit of a nostalgia trip for me, since I was brought up in the Catholic tradition. The mass was entirely in Polish, and the congregation was almost entirely Polish, and I enjoyed saying all the English responses on top of the Polish ones and seeing how well they fit (I also did it sotto voce over the bits the celebrant said too). Yes, the rituals are evidently frozen into my memory.

It’s exactly the same structure as the masses I attended hundreds of times during my upbringing, and I’m amused that I remembered everything even without being prompted by the company of English speakers in my surroundings. Very enjoyable to see the kids all done up in their finery, all nervous but excited, as they know it is all about them. Fun to see other remnants of my childhood imagery in the form of a super-splendid Sunday hat – so rare these days – and generally people of a certain look that’s so familiar from Catholic churches I’ve see in several places around the world. With that and the excellent food and conversation at the reception afterwards, despite my being tired from having only two hours sleep last night (more later), it was a lovely day.

Here’s a thing, though…

The Universe Laughs

So here’s a little irony. On Wednesday which was, I note:

(1) The day before Bike To Work Day in California…

(2) The day after I replied to a commenter that the extra investment in getting a folding bike like mine was well worth it (over getting a cheaper model) since -among other reasons- cheaper models would be more likely to fall apart while mine will last a lifetime…

I set off at 1:10pm on my bike to head (via the bus) to my office at USC, photocopy the final I’d spent the morning refining, and arrive at class at 2:00pm to set the final. Everything went fine, as usual, and as I did one last turn after waiting at the lights to head into the home stretch to catch the bus…

…my bike suddenly lost power. The chain had not slipped or broken though… An examination revealed that the crank arm/lever had completely broken away from the wheel holding the teeth and the chain. To be fair, I put an awful lot of regular stress on it (see below), but isn’t that ironic?

I got off the bike and wheeled it briskly to the bus stop I was headed for, managed to [..] Click to continue reading this post →

Ferrous Thoughts

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 soldering iron, meter, …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 →

Final Thoughts

Well, it was a full day. Since this morning I’ve been putting the last touches on a paper with my student, V. I’ve been working at my home office (something odd going on with my office computer) while he’s elsewhere but present via IM. We can chat, exchange equations, drafts, and so forth, so it is good medium. Then mid-morning, I had a moment of confusion for a while, and progress stopped while I sorted that out. Discussions with V and another student, T, via IM about this and some other matters ensued, and then I was back on track, inputting edits from a session yesterday of reading it with pen-at-the-ready in a bookstore, inputting edits from V, and then another printout and review to add more.

duvel, bike, etc

Every now and again, a check of email, a walk around and a pull of the odd weed in the garden, and then back to it. Somehow this went on until 3:00 – three hours […] Click to continue reading this post →

Idiocracy

Three things:

(1) Did you, like most people, miss the movie Idiocracy* last year? It looks like yet another lame comedy, but bear with it. It actually isn’t, really. It is one of the best indictments of what seems to be happening to a large part of the core of our society that I’ve seen in a while. You know what I mean… lower and lower thresholds for waiving all sorts of basic things that were once part of our required education… not just the awful spellings on signs that some of us whine about (sometimes too much, I’ll admit), but the necessity to use a severely reduced vocabulary to make yourself understood in the local store…or the lack of patience people (and the media) have for a reasoned, structured argument, focusing rather on looks, personalities or sound-bites (look for example at some the political headline discussions in both US and UK news at this moment)… the worry that fewer and fewer people seem to read a book from time to time**… The fact that nobody who works in stores seems to know anything about the merchandise they are employed to sell you… Or that situation you’ve had where the person behind the counter gets confused and can’t serve you because the item that you want to buy does not have a little picture of it at the checkout that they can click on in order to ring up your order/total…

Well, this film imagines a future where that sort of thing has become the least of your worries. The “dumbing-down” has just continued unabated. Everybody is essentially […] Click to continue reading this post →

The Earthquake

Comments Off on The Earthquake

[Update 19/05/08: It is expected that well over 50,000 people have died. There are several updates on the NPR sites mentioned below. See a BBC article here for a recent summary.]

Well, they’re estimating 10,000 casualties so far from the earthquake in China that measured magnitude 7.9 on the Richter scale. NPR’s Melissa Block and Robert Siegel were actually in the area when it took place and they are filing lots of reports. Melissa had her equipment running at the time of the quake and so you can hear her reactions here. […] Click to continue reading this post →

It’s Bike to Work Week!

blog on a bike!It’s bike to work week here in [LA] California again! Do consider participating (even if it isn’t where you are…) The MTA here in Los Angeles is doing a good job of pushing the idea that biking to work is a good alternative to fighting with other drivers on the highway*. Have a go! (I’ve been noticing more cyclists on the roads in the city in recent times, by the way, so you won’t be alone.) [Update: Click here for the website of the California Bicycle Coalition for events near you.]

If in LA, pop over to the MTA website. They’ve got a number of things going on. There are pit stops along the Red Line today, and on Thursday, if you show up on a bus or the subway with a bike helmet, you can ride for free! (I wonder if they actually bother to check if you have a bike with that helmet…?)

And get this… I’m a bit shocked by this, but if you pledge/register for the bike to […] Click to continue reading this post →

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 →
