Strings 2007: Share the Memories

trees near the aspen center for physicsA big chunk of yesterday (recall, I’m visiting at the Aspen Center for Physics) was spent chatting with old friends in the field I have not seen in a while, including going for a walk or two in the local surrounds with colleagues, discussing some of the physics issues of the day.

One of the things that comes up a lot with everyone I spoke to (and met at lunch, and in corridors and so forth) was Strings 2007, the big annual meeting that was held in Madrid last month (blog post here). It comes up in the form of people asking each other things like: “were you at Strings?”, “what did you think of Strings?”, “what were your favourite talks?”, “is there any interesting gossip about…?” (where the latter is not necessarily directly about physics).

So it occurred to me that some of those conversations and responses might be useful to workers in the field. Of course, you can just sit and work your way through the entire collection of online talks, a good thing to do. But it’s interesting to hear from others what talks they liked, and why, just as we do (and maybe have done) over tea and coffee in lounges all over the world after someone returns from a meeting. Often, this is where we hear of some excellent work by the less famous speakers (or even by someone who did not talk at all), etc.

So I’ll kick off. Although I was not there, and have yet to start a serious assault on […] Click to continue reading this post

Twenty Thousand Bikes

velib bike from parisSo, has anyone who reads the blog used the new Velib system in Paris yet? A new layer of public transport has been rolled out (yes, I know) onto the streets of Paris, as of last Sunday (July 15th). The Bicycle. A publicly funded scheme (familiar to some from elsewhere, such as Lyon and Amsterdam (?), if memory serves) called “Velib” where there are special bike racks all over the city. One of the (charmingly European-looking) bikes is pictured on the right. From a BBC story by Emma-Jane Kirby:

The local authority in Paris has deposited 20,000 heavy-duty bicycles in 750 or so special racks around the city and anyone who wants one simply swipes his or her ordinary travel card and pedals off wherever they want to go.

The bike does not have to be returned to the same pick-up point – you can take a bike from a rack near the Eiffel Tower, cycle to the Pantheon and leave it in the nearest Velib stand there.

This sounds great, from my point of view, you’ll not be surprised to learn! I’m finding it hard to see a downside here at all. A bit more:

The Velib scheme is aimed at people who are making short journeys.

The first half hour of pedalling time is absolutely free but, if you fail to return the bike after 30 minutes, you get charged an extra euro and the penalties go up the later you are.

(So European… penalties. They could not find another, more positive word?)

The Velib website is here. And of course it is only in French. What did you expect? (Actually, it is rather entertaining to read, all the same, since it is mostly easy-to-guess French, and knowing the context helps.)

I can’t see what’s stopping such a system from being introduced in cities in America. I think that we should start with….. Los Angeles, of course! It is one of the cities that […] Click to continue reading this post
