Nostalgia Furniture

New acquisitions. I’ve been a fan of the work of Marcel Breuer for many years now, going back to my first postdoc in the early 90s, at the Institute for Advanced Study in Princeton. There, I lived (over three years) in some lovely 1957 apartments designed by him, with furniture of his design in them too. (It’s a bit different now, I understand.) The Wassily (or, Model B3) chair is one of my favourites of his, and two days ago, when I got an email from a friend I’d not heard from in a while that she was getting rid of a leather-finished pair of them, I went to see them as soon as I could (especially when I heard of their colour, which I’d decided would match my floors rather well). I came back from the visit with (after some negotiations and handing over of payment) the pair and set them up.

Yes, they are just as wonderful as I recall (and this set is particularly well made – very good reproductions), beautiful, very comfortable, and a good fit for my living room… […] Click to continue reading this post →

I’ve had a fun time over the last few lectures with some more mature topics, pointing the students to things that they will see more (I hope) in the advanced class next semester. We covered the large N Gross-Neveu model in some detail, giving me the opportunity to give a glimpse of several important topics and techniques… at large N the 2 dimensional model’s solution is exact, and it shows important phenomena such as spontaneous chiral symmetry breaking, dynamical mass generation for the fermions and dimensional transmutation. These are all important phenomena shared by (the more difficult to study) quantum chromodynamics, the theory of the strong nuclear interactions. (See an earlier post about some of these properties and what they are… there’s also a mention of a new general level book that goes into some detail on the physics and the history.)

The other thing I took some time to explore was the diagrammatics of the model, and the interesting patterns that emerge […] Click to continue reading this post →
