‘Tis the Season

By | | , , , ,

There are a lot of silly, ill-informed things said about Los Angeles, mostly in the form of lazy clichés. Sometimes said by people who are otherwise quite sensible, but the power and groove of a truism is hard to resist, even when it is an untrue one. One of them is that there are “no seasons” here. This is just a silly thing that people say in place of saying that they are used to seasons from a different climate and they have not taken the time to listen and watch for the march of the seasons that is evident here. (I think also that we have it amplified by popular culture that the standard symbols of the Spring, Summer, Autumn, Winter cycle involving snow and red and gold leaf colours and bare trees and jack frost nipping at your nose and so forth are “the way things are supposed to be”.) A friend of mine has in her email signature the slogan “I have a life. It is just different from yours”, and so I will retool it here: “We have seasons. They are just different from yours.”

jasmine_in_bloomJust like anywhere else, the seasons wink or call (sometimes even shout) at you through certain combinations of colours, smells, temperatures, and so on. I think people miss a lot of cues in Los Angeles because they don’t get out of their cars and walk the streets very much. Even a few gardens or hedgerows passed along the way can show a lot about the mood of the season the city is in. For me, colours and smells are very big cues in Los Angeles, and there are times when large parts of the city seem to be dominated by a single plant’s smell or colour or sometimes both. For me, it is the Jasmine time of year now. This is when the night-blooming jasmine bushes (cestrum nocturnum, apparently) of the city all seem to work in concert and fill the air with a great scent, and lovely clumps of creamy […] Click to continue reading this post →

Rain, Dear. Games. (1)

double_rainbow_small So today’s rain-storm-driven activities involved staring out of the windows at various impressive downpours and marveling at the lightning and thunderclaps. This latter formed an interesting coincidence since I was reviewing grant proposals this morning, and one of them was about the science of certain types of high energy phenomena associated with lightning bolts. They were good to see, since Southern California (at least the LA part) has relatively few and relatively lame offerings in the way of thunderstorms. I miss them terribly.

In the early afternoon, we finally decided to go off to a museum. A good indoor activity. However, we got caught in a downpour between parking and museum and decided that, despite the two giant umbrellas we had deployed, our coverage was wanting and we were all too damp to continue. So we returned home. It was a good […] Click to continue reading this post →

Collapse Results From Space

montserrat_dome_collapsePhil over at Bad Astronomy has posted about my childhood cradle (although I am sure he does not know that), the (still beautiful) island of Montserrat. I grew up there for ten years from ages 4 to 14. Many years later, in 1997, a volcano erupted there (in the “Soufrière Hills”) and devastated much of the Southern part (where I grew up) of the island wiping out almost all traces of where I lived. Much of the stuff of my childhood memories is buried under tens of feet of ash. In my more tender moments, this thought still brings me to tears, actually. (Yes, of course I do know that it is much more devastating for those whose lives it affects due to their living there in the present.) On a side note, I always find it slightly chilling that the mountain that erupted was one of a pair that I used to love to sit on a giant rock and stare at, for long periods, when I was in a contemplative mood (as I often was) when I was young. Furthermore, two weeks before the eruption I was actually visiting the island for the first time since I’d left it as a child. And guess what I did? One day I was in a foul mood over an issue, and I went and sat on that rock again and while brooding, looked over at the mountain for a long spell. (Just in case, I try not to get too angry these days… 😉 )

It turns out that the volcano has continued to rumble and burp over all these years, sometimes dangerously, with a growing dome that forms on top of the whole […] Click to continue reading this post →

Smarter than the Average Panda?

yun-zi-01 Yes, I know: (1) Large head doesn’t make one smarter, but it was just so I could use the post title. (Maybe one or two of you see where it comes from…) (2) The final resort of a busy blogger: – cute animal pictures. Well, I already regularly share pictures with you concerning what I had for dinner, so no change there.

Blue Skies…

By | | , , , , ,

I always like an excuse to look for blue skies, and to have others look too, even in the worst of times. I had a great reason to do it today.

Early this morning before sunrise I settled down to write my ten o’clock lecture for my Electricity and Magnetism class. On Tuesday I had ended with a computation that is the essence of the reason the sky is blue, which is a nice enough thing to talk about, but today I wanted to go more in depth on the whole thing, and show that you can in a few steps show that the blueness has a particular pattern to it. I wrote out the final equations in a few steps and looked at them for a moment or two and realized that with the sun rising at that very moment, it was the perfect situation to have! So I went outside to enjoy the beautiful Autumn day and the beauty there is in seeing an equation writ large in the sky – and it really was all there.

It is particularly at times like this that one remembers why it is that it is hard not to just love Physics! (I hope you’ll forgive my unashamed love of what I do.)

Here is the sky I saw, looking toward sunrise, and directly in the opposite direction:

Oh, you’re wondering what I am talking about..? Why is the sky blue? What pattern in the sky? Thanks for asking! There are two things I’m looking at. First, light from the […] Click to continue reading this post →

A. S. Byatt

Following hot on the heels of Margaret Atwood coming to town last week (over at UCLA), we have A. S. Byatt over at USC today! Very exciting. It is actually partly one of our College Commons events as well, and last week as a College Commons event (with a Darwin tinge) we had a viewing of the film of her book Angels and Insects, which I thought was really excellent!

Her lecture is entitled: “The Novel as Natural History”, (and will resonate with some of the themes I talked about in my report on the CC event about Collections) and I expect it is going to be quite wonderful. Details here, and the blurb goes:

jane_goodall_bovardJust went to a marvellous talk by Jane Goodall here on the USC campus, in Bovard auditorium. She’s signing her new book as we speak! Among the many things she said, she emphasized one of my favourite themes with regards the environment (and so many other things, like community, education, etc): Act locally.

Have a look at her roots and shoots organization for example. It is very youth driven […] Click to continue reading this post →

Collections!

Well that was fun! I’m sitting on the bus on the way home [editorial note: I wrote most of this on Thursday afternoon], with the memory of the College Commons event that I just went to still fresh in my mind. (That and the tasty food at the end of the event.)

ivory-billed-etc

This event (“Discovering the World: Collections, Curiosity and Evolution”) was all about collecting and collections, from the institutional collections we have in our society today such as museums and libraries, through the “cabinets of curiosity” of earlier centuries, to the sort of obsessive collections of random stuff that sort of becomes a disease (I mentally glance over at the shelves, piles, and boxes of old New Yorkers in my house; I’ve not been able to throw away a single one since I started subscribing in the early 90s. Yes, I know, I know… I know.)

So many of these types of collections (and the resulting books and compendia which they themselves become the objects of collections and subjects of books and so on and so forth) formed the foundations of the culture, the raw material for scientific study, the inspiration for more collections and for more study, and so on…. So the event used that as a basis and dug out some wonderful articles for us to look and marvel at. The digging was done at USC’s own splendid Doheny library (original Audubon volumes, Cook’s journals, etc) the Huntington library (several illustrated tomes of natural history and an actual plate used long ago for printing Audubon illustrations which were then later hand-coloured by artists) and the Los Angeles Natural History Museum across the street. A number of my colleagues who are scholars in areas that these objects pertain to gave short, informative and […] Click to continue reading this post →

Pit Visit

I promised a report on last week’s College Commons trip to the Page Museum at the Tar Pits, here in Los Angeles. It was an excellent trip. The usual thing I do for blogging these things is, some time later, as time allows, I sit down and do a sort of brain-dump. I tried to do something different this time, and walk on the tour with my Palm Tungsten (yes, really really old technology, I know) and simply write a sort of narrative into it as I went along. Then I combined the uploaded file with the images I took as I went along, and supplemented with some extra sentences here and there. The overall effect should be a sketchier description of the event than I usually do, which may or may not be an improvement given that everybody seems to skim everything these days anyway. (Click on the photos for larger views.) So, here goes:

tar_pits_trip And so it begins. And it begins well – after a name tag is given out, upon check in for the bus, we are given a little brown paper bag of snacks. Hurrah!

3:39 and we’re off! (We run by the excavations for the Expo line and since it is an elevated bus, I get a nice view of what’s going on for quite a way. Wish I’d had the camera out to make a video for you.)

My colleague David Bottjer, a paleontologist, gives a little run down of the history of the region (both social and paleontological) as we go north on La Brea (appropriately – they are the La Brea Tar Pits… Or given that La Brea means The Tar, they are The Tar Tar Pits…)

4:05 We’re here! Somehow, the little bag of goodies is all empty already. Except for […] Click to continue reading this post →

Snow!

Today’s shooting circumstances (see previous post) produced an unexpected bonus: Snow. Lots of it! It is always a pleasant surprise to me how quickly you can get from Los Angeles to some good snow cover. I was not expecting to see any snow – or trudge through any – this season, but it turned out that lots of it had fallen where we were scheduled to shoot. So much so that we could not get to where we wanted to […] Click to continue reading this post →
