I forgot to post this yesterday, when it was more relevant, but here I go anyway. I’m not looking to offend anyone here, I’m just curious, and have been puzzled about this for years. I’m reminded of it every year at about this time. What am I talking about? Wimbledon.

venus williams wimbledon 2007 (AP Photo/Andrew Parsons, PA)Not the event itself (which I have not followed in over a decade or so) but the word, or rather its pronunciation. I’ve noticed that a lot of people in America – from people I encounter day to day to newscasters on NPR – seem to get very confused about the “d” and pronounce it as a “t”. So you get people talking about the “Wimbleton” final a lot at this time of year, especially when someone from the US is in it (see photo at right [credit: AP Photo/Andrew Parsons, PA]). Has anyone else noticed this, or is it just my hearing? (Or worse, perhaps it is pronounced with a “t” and I’ve just not been paying attention all these years, and somehow I just hear it more clearly over here when some people say it.)

I’ve been wondering why this happens. Here’s some additional data, I’ve painstakingly […] Click to continue reading this post

Fluored

Here’s a little bit about how fluorescent lamps work, from Wikipedia. The old-style big fluorescent lights you recall from a while back (with that more industrial or corporate feel) are very different than the modern compact fluorescent lights many people would like to see used more in your homes (and elsewhere). This produces a lot of […] Click to continue reading this post

Memorising Mingus

Mingus Lives!

Just now I noticed to my horror that it was on the 1st of September of last year that I intended to get around to repairing Mingus, my G4 powerbook, at the time the main workhorse of my away-from-campus computer arsenal. There was an unexpected failure which I could not figure out the source of, and I managed to get it partly alive -alive enough to drag about 12 GB of data from the hard drive via booting it as a target disc of an iMac, Ella. Well, I never sent it off as I was (1) thrown by the fact that I had no coverage on it, and so any repair would have to be paid for, and (2) in the middle of the semester – a really busy one – and so I did not really have that much time to devote to the issue.

Well, it all got put on a back burner because I decided to use my teaching laptop (a little iBook) as my main laptop -just for a week or two, I told myself. Eventually, last […] Click to continue reading this post

The Cat

The Cat

  by Ryan Alexander

She came to me skittish, wild.
The way you’re meant to be,
surrounded by cruelty.
I did not blame her.
I would do the same.

A pregnant cat, a happy distraction;
some sort of normal thing.
Calico and innocent.

The kittens in her belly said feed me.

And I did.

She crept with careful eye,
Body held low to the dirt,
Snagged a bite,
And carried it just far enough away.

She liked the MREs,
the beef stew, the chicken breast, the barbeque pork,
but she did not like canned sardines.
I do not blame her.
I would do the same.

She came around again and again
finally deciding that I was no threat,
that this big man wasn’t so bad.

I was afraid to touch her as the docs warned us. […]

Consider a Spherical…

So I went out to get a new kettle a few days ago. I’ve now given up on a rather lovely design by the company Chantal that I’ve been using for many years since on two models in succession (or is it three?) the same flaw has revealed itself – the plastic parts of the Hohner whistling lid began to loosen gradually (probably from too much heat up the sides, which may be my fault) and then you eventually end up with a non-fitting non-whistling lid.

I began to assess other kettle designs, and in doing so found myself thinking idly about a number of physics issues. One of the main ones was energy. If I got a smaller kettle (the one I had before had a capacity of 1.8 quarts, and I was considering ones as big as 2 quarts and ones as small as 1.5 quarts), which I was leaning heavily toward, it would probably encourage me to save energy and not boil so much water. On the other hand, maybe that’s really silly, since I might just be putting the same amount of water into the kettle anyway… I’d never fill either up all the way in any case. But if I put the same amount of water into both kettles, would the smaller one end up using less energy anyway as I don’t have to heat up the extra air in the chamber, or does that not matter…? It’s not that simple since the chamber is not sealed. Hot air (and later, steam) is escaping all the time. Well, this is all complicated by the fact that the smaller kettle has less of its base in contact with flame, so I’d have to turn down the flame, and heat it for longer on a lower flame than with the larger kettle… would that make a difference? Perhaps a smaller chamber at lower flame means slower steam escape velocity, and so a quieter whistle. Not good if you’re prone to forgetting that you’ve put the kettle on during an absorbing computation…downright dangerous, in fact!

This was not an entirely serious discussion, you see, but it’s sort of fun sometimes to find these things floating around in one’s head. Physicists (and I imagine, other scientists) have this sort of thing flit through their heads a lot. The key thing -especially as a Theoretical Physicist- is knowing when to engage with one of these problems, and when to ignore them. Is there are clear route to tackling the problem? Is it worth it? Is there something to be learned from solving this problem that might be useful elsewhere? In fact, I was trying to explain this all to a writer friend of mine […] Click to continue reading this post
