[Post reconstruction in progress after 25.10.07 hack (body, comments and images to follow)]:

We had rain again! Quite a big deal here. Well, this meant that some rose bushes that I’d been letting grow well out of control were bent over with the weight of the water. So lots of pruning yesterday. Here’s one of the sweetly scented blooms I harvested along the way:

Some of What Matters

Below I’ve reproduced the text of the approximately 20 minutes of that which I presented at the What Matters to Me and Why event on Wednesday. I mentioned my preparations for it in a previous post. The event was well attended, in an excellent setting (a hidden campus cafe I’d somehow not known about before, Ground Zero). There were students, faculty, staff, alumni, and several others. I chose to give a structured address to start so as to make sure that I did not go on for too long, as I might in a more off-the-cuff delivery. I very much wanted to leave plenty of time to interact with the audience through their observations and questions. I delivered it partly from memory and partly from reading, and wanted it to have a bit of a feel of being read a story, rather than a formal speech. I don’t know how successful that was, but it was fun for me. I think I might try that approach again some time.

Overall, I think the event worked well, and I had a great time. A number of people (kindly) said at the end that they had a good time, and I hope everyone else did too!

Hello Everyone.

First let me say that it is an honour to be here. I’d like to thank everyone concerned for inviting me to speak in this series. I imagine that everyone starts their piece by saying that they struggled to find a way of saying What Matters to them and Why in a short time. So I won’t dwell on that, except to say that it’s especially hard when, the day before preparing, you realize that it’s not going to be that hour long presentation you were expecting to squeeze your essence into, but 20 minutes!

Some time ago, when people started mentioning that they’d seen that I was a guest in this event, and that they were looking forward to hearing what I will say (!), I’d respond that I too was curious about what I was going to say, and would also try to show up and find out. This was actually true. The other thing that I (half-)joked was […] Click to continue reading this post →

What Matters?

palm flower frondsI’ll let you know.

Huh? Today, I’ve to think about two things I have to talk about over the next couple of days. I’ve to give a physics seminar on Thursday at UCSB, but more urgently, I have to think about What Matters To Me and Why. Why? This is because in the Spring I agreed to be one of the presenters of the four-times-a-semester USC event of the same title, hosted by the Center for Religious Life. This excellent series is run by Rabbi Susan Laemmle, the Dean of Religious Life, with a committee of students. Here’s how it is supposed to work (extract from their site):

At each WMMW session, the featured guest spends about twenty minutes addressing the topic “What Matters to Me and Why,” and then the floor is opened to informal dialogue for the remainder of the hour. Just as there is no one way to address the topic, so there will be no one direction in which dialogue will proceed. The student contact from the WMMW committee introduces the speaker and makes sure that the session goes forward in a professional yet friendly manner. An indirect purpose of WMMW is to maintain an arena in which people can talk about important, personally charged questions in an open, mutually respectful way.

A typical session is described here. This is going to be a tough one. Not because nothing matters to me but because everything seems to matter, and I cannot effectively rank these things to say what matters most in any way. I only learned yesterday that I only have about 20 minutes to say what it is that matters. This either makes things harder or easier, I can’t decide yet. Probably harder. Now I really have to think.

I jokingly thought a few months ago that I ought to just look at my last few blog posts the day before and just talk about what’s in those. What can I see… Well, there’s public transport, community and the environment, composting and gardening, science and television (and scientific honesty). Not bad. (Good thing I did not do that post on dating. Probably not a good topic for WMMW…) I can probably weave something out of those. Do I blog about those things by accident, or because there are some themes there that are being brought out? What are the big themes in those then? Random scattered thoughts follow….

Composing Compost: Fun with Microorganisms

So finally I completed the project that began with the chicken wire matters I spoke of a while ago. Work and such things have a way of intervening for weeks, preventing a good idea from going from conception to completion in what should be a day or two. The plan? To stop throwing away lots of wonderful organic matter and keep it instead, turning it into compost. This makes sense because so much of my garden has rather poor soil, for a start, and for a second matter it just seems wrong to not do it. for a third, it’s fun to do experiments with some microbiology for a change. Microbiology? Well, the object of the exercise is to let nature turn any organic material that you have into compost – full of nutrients for growing new things. Compost is also good for moisture control, good drainage, and a host of other things that are beneficial to plants in the garden. How does nature do this? Bacteria, mostly. But for the bacteria and other microorganisms to do their job (digesting the material), one needs to give them good conditions to live in. Conditions involve the right amount of moisture, air, and food, and the point of my project was first to prepare containment for the compost manufacturing process, and then to prepare a good combination of raw materials, place them properly, and then leave the little organisms to their own devices to do their thing. Here’s a good webpage at Cornell about the various stages of composting, the temperatures involved, and the various organisms (bacteria of various sorts, actinomycetes (a kind of filamented bacterium), fungi (various molds and yeasts), protozoa) that come into play at the various stages.

compost projectSo, phase one: Containment. Well everything is going to be kept together with a cylinder of chicken wire, and so measurement of the desired radius [tex]r[/tex] followed by a quick computation ([tex]d=2\pi r[/tex]) to give me the length I needed to cut, and I was away. Shortly after I realised that my measurements were to be determined by the size of the mouth of the large trash bags I’d bought to add as the liner of the containment cylinder. So I ended up readjusting everything to fit that. I cut everything a bit big to allow for the overlap I […] Click to continue reading this post →

Rain!!!

Finally. I never thought I’d see the day again. Finally and end to the seemingly perpetual sunshine. It has not been since March (unless I’m very mistaken) since there’s been any serious rain here, and more than five months since there’s been any officially measurable rain of any sort in Los Angeles (as measured by the official station down at USC).

I was beginning to despair a bit. I need rain, psychologically as well as for more mundane reasons like wanting my garden to get a good soaking. There’s something about the way my outlook on the world works that needs to have good rainfall sometime. Rainfall where I live, I mean. I’d seen some wonderful rain over the summer (almost daily afternoon thunderstorms in Aspen for a few weeks, nice rain and drizzle for a week in Cambridge), and that did help me with the waiting, but I’ve been needing rain at home.

And so here it is! There’s the wonderful sound of it on the roof, and then there’s the […] Click to continue reading this post →

Soon They Will Come

So the mexican sage (salvia leucantha) has started its new crop of flowers. The purple bobs pictured below right mexican sage(click for larger – yes, there is a little bee resting quietly on a leaf there for some reason) will turn into long purple fronds with lots of individual bells containing flowers. Soon they will come, and they will keep coming. They’ll come and examine each flower closely and attentively, and I’ll be waiting for them, since they are so magical – appearing suddenly and dramatically as though dropping out of warp, with a wonderful and powerful hum. I’m talking about hummingbirds, of course. They love these flowers, and come and feed on them regularly.

The warp reference? They are fast – incredibly fast, and they can accelerate and decelerate astonishingly effectively. So if you’re lucky and standing still at the right point, there’ll be a hum and suddenly one […] Click to continue reading this post →

Chicken Wire

That’s such a lovely sound. Chicken wire, or maybe better: “chickenwire”. (I would put it alongside “cellar door”…[update: almost. I suppose it is not as transcendent, really.])

I digress. I just thought I’d share with you a picture of the things I went to the hardware store to get last night1 (Click for larger view):

    chicken wire project

  • Several feet of chicken wire (it really is called that on the labeling, but better: Poultry netting. Excellent. I like the idea of going home to construct an enclosure for my wayward happy fat chickens), 3ft high.
  • A collection of bricks (I chose some nice miniature ones… they called out to me while I was trying to find the regular bricks).
  • Large black plastic bags. Heavy duty.
  • Steel wire.
  • A 25 inch machete. Annoyingly, it comes from the store so (deliberately) blunt I’d be better off using a wet fish to perform the tasks intended for it2. Going to have to put an edge on it later.

Yes, you guessed right, I’m going to be constructing something. Any idea what the project is?

But I won’t start now. Just got back from a hike over at Runyon Canyon among the […] Click to continue reading this post →

Return to the Nest

Sorry about the silence. Odd thing: As a result of my (I think) growing absent-mindedness, it turned out that my flight was on Sunday night and not on Saturday night (as I thought when I did the previous post), so I suddenly had an unplanned 24 hours on my hands in Aspen.

ground dove nextI decided to spend the extra day lying low getting some work done – various things I thought would get undone on this trip suddenly had another chance to get done! Mostly administrative stuff. It is amazing how much one can get done when there’s a whole extra day suddenly appearing in your schedule, and so that’s what I worked on.

One thing I could have done was reminded you that the Phoenix was due to launch Saturday, and indeed it did! Be sure to check out a post about it on the Bad Astronomer with some links to really nice launch videos. The Phoenix mission plans rather wonderful things when the craft gets to Mars (including making the old reverse-thrust landing maneuver vogue again), as you can learn from their site.

phoenix spacecraftToday, Monday, saw me running errands. Boring things, really. Things you do after being away from the nest for three weeks. Anyway, I’m trying to get to used to all the extra oxygen, and the unbelievable dryness. There’s still been no rain. I will miss the daily downpours and thunderstorms of Aspen. This leads me to the garden report. Nothing to say except that there’s been a bit of loss – the relentless sun and dryness […] Click to continue reading this post →
