joke hollywood star of brian greene Sometimes the journalists and editors get it right. In fact, they get it right a lot of the time, but you hear more about the complaints (sometimes from me, sometimes elsewhere) about them getting it wrong, when it comes to things like science coverage especially. What am I talking about? I’m talking about the set of questions and answers that are in a new article on MSNBC that a number of people pointed out to me yesterday and today. It starts out as an article about Brian Greene’s science outreach efforts (books, and tv and movie appearances, including a new one), with some discussion of how this is regarded by his colleagues, the value it has had in raising public awareness of physics (and fundamental science in general, I would argue), and so forth. All that is interesting, but not nearly as interesting to me right now as the later parts of the article which is simply a question and answer session. (Picture above right is from a fun joke I carried out last year that you can read here – be sure to read the comments too.)

Alan Boyle, the science editor, asks Brian a series of very thoughtful questions, and Brian gives some very thoughtful answers. The topics include research in string theory (of course), hopes and possibilities for experimental and observational results (such as from the LHC and Planck) that can inform and ultimately test the ideas coming from string theory and open up new vistas in fundamental physics, research on issues such as the landscape and the idea of multiple universes, research on better developing our understanding of string theory (to the point where we can, it is hoped, extract firm predictions from it), and many other things. (I wrote an introduction to aspects of the landscape issue here, and talked a bit about a Tom Siegfried article on the discussion amongst researchers here.)

It is nice to see an honest, non-inflammatory and non-hyped conversation about the issues, and read Brian’s personal take on some of these matters. The bottom is, […] Click to continue reading this post →

All Hands on Deck

all hands on deck Well, it’s the middle of the Bleak Midwinter, and the first day of classes of the new semester. Mine start tomorrow. It is time to get myself back into the classroom-teaching frame of mind -although to be honest I don’t think the break was long enough for me to have got sufficiently far removed from it: 85% of the research tasks that I wanted to do during the break remain undone.

Anyway, I must sit and contemplate what I am going to talk about in the graduate course entitled “Selected Topics in Particle Physics”. It’s my lunch break, so I thought I’d chat to you for a bit.

Rumour has it that everyone is expecting some sort of string theory course, reasonably complementary to the one that my colleague Nick Warner taught here two years ago. I’ve no interest in just teaching the standard string theory topics – a good and motivated graduate student can just look them up in a book if motivated enough (if they can’t they’re in the wrong business) – and so I’d like to throw in some material that is not packaged together in the standard way, and give them an education that emphasizes powerful ideas and techniques that are relevant to more than just standard string theory research, but theoretical physics in general.

You see, this is one of the wonderful things about the topic that you don’t hear about much when people say things (and write books for a general audience) about how much it is supposedly taking over smart young minds and leading them astray: It is a fantastic framework for training good physicists for whatever new and useful ideas and physics will come along in the future, whether it is string theory or some other topic. The point is that string theory has developed in so many different ways, and […] Click to continue reading this post →
