The Hat

Here’s a strong clue that I’m supposed to be working on writing slides for an important presentation:

Albert Einstein in Aretha Franklin s Inauguration Hat

Yes. I’ve been playing with photoshop. What’s the story? Well, I noticed that there is a facebook page for Aretha Franklin’s wonderful Inauguration hat. You know the one. The page has a huge number of fans already, growing at a rate of something like 200 every ten minutes (when I last looked). People are adding photos of themselves, their pets, and other objects, all wearing the hat. It’s great!

So I, rather than settling down to design those slides I’ve been meaning to get to for the last few hours, thought I’d join in the facebook fun! I could not resist sneaking […] Click to continue reading this post →

Hope

Hope. This word has been used a lot in the last year or more. Sometimes it felt to me like it was overused, but now that the dust has settled, I think I’m quite sure that it is a good word to describe where we are, or what we have. Beginning early today, there will be a new President of the United States, Barack Obama. He’ll be bringing in a whole new regime that seems, given what we’ve seen so far with the work of the transition team and the various appointments to key positions, determined to do some truly good things. (See several related posts listed below.) There’ll be several huge obstacles to fulfilling the promise and potential of the new regime, some known, and some unknown. It’ll be hard to firmly move forward, but it is hugely encouraging to see the looks of delight and joy on people’s faces during these days of celebration, and to hear about their engagement with the idea that we can pull together and move forward on so many fronts on so many vital issues. We don’t know what will come to pass, but one thing we do know is that there is a marvellous window of opportunity. There is Hope.

Since the election result on the night of 4th November 2008, with all that had been achieved and overcome still fresh in the air, right up until today, there’s actually been a rather fitting song ringing in my head when I think about all of this. I find the chorus from the song “I Live In Hope”, by a musician friend of mine, Libby Lavella (you may recall her from posts here and here) extremely evocative of the mood.

So where am I and what am I doing? I’m in chilly Cambridge. The one in the UK. It is super cold over here. When we landed in Heathrow at lunchtime yesterday it was below freezing, and the thick cloud of the London sky was right down to the tops of the airport terminals. Everybody seemed to be talking about how cold it was. My wandering in central London for a few hours dragging my suitcase (before heading to Kings Cross and the train to Cambridge) was quite a bit uncomfortable – at least until I realized that a key mission should be to find on Oxford Street a branch of Marks and Spencer’s (now called M&S it seems… interestingly across the street from an H&M, and not so far from where the doomed C&A store used to be…) and buy some long thermal underwear. A bit elderly, perhaps, but very snug and warm against the icy winds and snow flurries, so I don’t care. (Yes, that probably falls under the category of “oversharing”, one of the words of the year 2008….)

Merry New Year!

pods on a tree at new year Yes, that’s right. You read Merry and not Happy.

I’m breaking the mould. I’m upping the stakes. I’m wishing one and all a year of merriment. I’m afraid it can’t be returned, so you’ll have to work with it as best you can. I’m certainly going to.

To achieve the mean of Happiness that the millions of Happy New Year wishes every year are evidently striving for, we need to be aiming for some Merriness from time to time to keep us on track at settling at this particular position on the multidimensional emotional landscape.

Someone has to take this important business in hand, and so I’m having a go, […] Click to continue reading this post →

Red, Yellow, Blue, Green…

red yellow green blue…among other colours.

View of the day from the garden. (Winter. Number x in a limited series of y.) (Click for larger view.) The rains have gone for a while. The sun is back, with clear blue skies to close out the year.

I’m trying to rest. Well, I’m working on various projects at home, mostly. Colours are on my mind a bit in one of these projects, actually. Later today I’m going to be down in the (only slightly mad-scientist) workshop making a portable screen on which to project films.

Projecting onto the wall is good, but I want to make a silver-grey screen with a dark border that will really pop the colours out. Some of this is about not projecting onto […] Click to continue reading this post →

Cracked

christmas crackers crackedAt some point during Christmas dinner (prepared in collaboration between my mum and I) I remembered that on top of a high cabinet, out of reach and almost forgotten, there were a few Christmas crackers from three or four years ago.

We cracked a couple, of course. Wouldn’t you have?

These were rather good crackers, with solid presents in them. We popped them open simultaneously, and used the rule that who got the larger portion of a cracker won its contents.

Summer Reading: Falling For Science

By | | , , , , ,
4 Comments

(Yes, I know it is not Summer (here), but I love the idea of Summer reading lists so much that I will continue to discuss some books under this series title, whatever the time of year.)

I just heard a piece by Robert Krulwich on NPR about the book “Falling for Science: Objects in Mind”, which is a collection of essays with an introduction by Sherry Turkle, who’s a social sciences professor at MIT. Krulwich says:

“…written by senior scientists (artificial intelligence pioneer Seymour Papert, MIT president and neuroanatomist Susan Hockfield, and architect Moshe Safdie, for example) and by students who passed through her classes at MIT over the past 25 years. They were all asked the same question: “Was there an object you met during childhood or adolescence that had an influence on your path into science?”

And after a tidal wave of Legos (7 different essays), computer games and broken radios, I found a few wonderful surprises. One MIT student reported how she couldn’t stop braiding her My Little Pony’s tail, weaving the hairs into endlessly repeating patterns (a clue, perhaps, to her fascination with mathematics)….[…]”

He goes on to interview software designer Joseph Calzaretta about his childhood encounter with stop signs. It’s a really nice story. The whole radio piece is here, with audio and transcript. (There’s another version here with the excellent “Eggs in a Basket” story emphasized instead.)

This is actually an issue that fascinates me, and I don’t think that the question should be quite as narrow as above – focusing only on people who went into science. I think that -especially as children- we are all scientists, exploring the world around us, […] 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 →

Snowed Under

Ok. It’s official. This week I am snowed under with things. Every day I write half a blog post, and then something comes up and I do not got back to it and I fall into bed later, exhausted, some time in the wee hours, only to get up early the next day to carry on with things.

So in case you were wondering, I am still here. Just snowed under. I gave my final exam for my Physics 151 course (Fundamentals of Physics: Mechanics and Thermodynamics) on Monday (hurrah!) and I’ve spent a huge chunk of today playing with various excel files of various chunks of data from the course, trying to turns a sea of numbers into final grades for the students. It has been slow work, and I’m nowhere near done yet. It’s complicated because I must incorporate multiple components of assessment, from three different exams, laboratory work, online homework and written homework, to in-class responses using individual RF transmitters, and online quizzes of various sorts. (All a bit much, in my view, but, well that’s another story…) Every single bit has its own spreadsheet with data that must be uniformized and then combined to give the whole picture of each student’s performance.

It has made me a bit dizzy just talking about it.

But it’s not that simple. Oh no. Here’s a small part of the extra stuff: I’ve been trying to get the exterior of my house painted, and of course there have been (quite fantastic) rainstorms delaying everything and so I’ve been dealing with painters for longer than planned – with the Christmas holiday closing fast, and I’ve got my mum visiting me (hurrah!) and so I must be a good host and so forth and not just hide in the study crunching numbers (she arrived a day earlier than I expected – my fault! – so I’m a bit off-balance about that too), and… and…

Teachers Rock!

Listening live (over a late breakfast coffee) to the press conference led by President Elect Obama announcing the Secretary of Education. Arne Duncan is the nominee. This is an underrated post in terms of how high profile it is compared to the other cabinet posts… but of course it’s super-important. So it is wonderful to hear the lovely speech from the pres-to-be (and also the one from the vice-pres-to-be). Just really great. It is especially good to hear recognition of the fact that the core of […] Click to continue reading this post →

Physics Intervened…

Comments Off on Physics Intervened…

Well, I’d have hoped to have done a post today on a few things, but physics intervened. Recall that the Southern California Strings Seminar is on right now here at USC, and since I am the organizer, I’ve been nipping about serving up piles of various types of tasty cookies (hunted down on a late night visit to Trader Joe’s last night – gotta have good cookies to go with the coffee you see), announcing the speakers, and so forth, as well as actually sitting and enjoying the really excellent talks that we’ve had from several young people. Day one (finished off with dinner, wine, beer, and chats with people from USC, UCLA, and UCSB at Bacaro) was just great and day two is in the morning and so I’d better finish up this post and get to sleep.

Illy Taste Test

By | | ,
21 Comments

Well, I did a bit of an experiment the other day. I tend to have Illy coffee when I am away – Originally in Italy, when I used to visit the International Centre for Theoretical Physics (ICTP) in Trieste, in the early ’90s. (Sigh….some very happy days were had on those trips…) At home, I routinely have reasonably good coffee made cafetiere style, using beans from GroundWork. Some months ago, however, I rediscovered one of my favourite stovetop espresso makers and started to use it again, grinding my usual coffee finer and getting quite a good cup. It started out as a treat in the morning, but gradually replaced more and more of my cafetiere cups of coffee. (Contrast here and here for example.) Then, after conversation with a friend of mine I found myself thinking about Illy coffee again and getting misty eyed. I got thinking – is it really as good as I remember it? Maybe it is partly just to do with being on my travels – the novelty, and some nostalgia for my days in Italy. Surely, a freshly ground set of good but non-Illy beans is enough to make as good a cup? I decided not to try this out, since I didn’t want to get hooked on the very expensive stuff when I was perfectly happy with my GroundWork beans.

But. I stumbled on a sampler pack of two 4.4 oz. cans of espresso preparations from Illy while browsing in a shop the other day, and so gave in.

Drat. Drat. It is so really very very good. And I’ve gone through one tasty can (the […] Click to continue reading this post →

Redemption

A few Tuesdays back, I went for an early evening hike in Griffith Park to get a burst of energy and clear out the mess in my head, as I am wont to do. I went straight and fast up to the Observatory and then beyond to Mount Hollywood’s lookout point. It was a lovely evening, with a number of people out and about enjoying it. This visit had a different treat than I usually encounter. There was a guy up there playing his guitar… and he was rather good to listen to. mount_hollywood_view_guitar_guy I listened to him for a short while and then he stopped (sadly, just before going beyond four notes of Purple Haze), as his fingers were getting chilly. I applauded, and he looked around, thanked me (not having previously noticed me listening there) and then started to pack up. Then he changed his mind and began playing just one more tune. Wonderfully, he started on one of my favourites, “Redemption Song”, which fit my mood then perfectly, fit with many people’s moods a week after the Presidential elections, and also fits my somewhat brooding and contemplative mood now. It certainly works well on this Thanksgiving Day here in the USA.

It was a lovely few minutes there in the low golden sunlight, with a sense of rest and […] Click to continue reading this post →

Tales From The Industry XXVII – Light Speed

By | | , , , , , , ,

Here we go again! Tonight sees another new episode of the new series of The Universe on the History Channel (you can watch it as a warm up to The Atom Smashers, on PBS), and the episode is all about the speed of light! I’ve no idea how this one will turn out, but for my segments we did some rather fun things to illustrate some of the key concepts. The main idea is that the laws of physics are rather different from ordinary Newtonian/Galilean ones when you are moving at an appreciable fraction of the speed the light. This is what we learned from Einstein’s Special Relativity. How do you illustrate this for a TV viewing audience? Well, one way is to imagine what would happen if the speed of light was a lot closer to everyday speeds. Then you could illustrate some of the effects in a fun way.

Well, one thing led to another and somehow (after a lot of email discussions of the physics with Darryl Rehr, the writer/director) it ended up that I was supposed to do […] Click to continue reading this post →
