On 18 March 2016 this conference celebrated the 50 years of philosopher of science, structural realist and rock guitarist extraordinaire Professor John Worrall at the London School of Economics.

The 50 years of Worrall took place on 18 March 2016 and include cutting-edge work on the philosophy of science, structure, and of course rock-n-roll, with an appearance by The Critique of Pure Rhythm in which Professor Worrall shreds the electric guitar. An unforgettable event.


Read the whole John Worrall story … and take a look at Worrall through the ages.

Graduate Essay Competition Winner

50 Years of Worrall held a graduate student essay competition. The winner of the competition was Laurenz Hudetz, a PhD student at the University of Salzburg, for his essay:

Laurenz Hudetz, “Strengthening Categorical Equivalence: Towards an Adequate Notion of Structural Equivalence of Theories”

Laurenz will receive a copy of Proofs and Refutations, and will be joining us to give a version the paper at the conference with travel and accommodation costs covered. We received many very strong submissions for this contest and would like to thank all the students who participated.


The morning session took place in the Hong Kong Theatre, on the ground floor of Clement House, Aldwych. After lunch we moved up to room CLM 5.02, on the 5th floor of Clement House.
