For those of you unable to attend the recent meetings of the Sigma Club, you can now view photos from our regular philosophy of physics lectures on Flickr.
The Sigma Club is a historic lecture series in the philosophy and foundations of physics, founded in 1987 by Michael Redhead at Cambridge, and moving to LSE in 1997 where it is now hosted by the CPNSS.
The Sigma Club meets on Monday evenings during regular term-time. Join email list
