As previously mentioned
, the Open Logic Project now has a separate repository for photos of logicians to illustrate your OLP-derived materials. They are automatically included in the biographies that live in
. I’ve just uploaded a whole bunch of photos that don’t have associated biographies (yet). Some of them are not well-known, even.
For the technicalities, I’ll repeat myself from the previous post:
We have a separate repository for photos:
github.com/OpenLogicProject/photos. We’ve separated them because (a) the licensing issues are more complicated: some of the photos are under copyright, and we wanted everything in the main repository to be available under a Creative Commons license; (b) the main repository would become very large if it included all these pictures. To use the pictures, clone the photos repository into the
assets/ subdirectory of your local OLP clone. There’s a PDF with all the photos on the build site.
Tracking down these pictures and getting permissions was (and continues to be) a surprising amount of work. Thanks to all the people and archives who provided them and granted permissions: the IAS archives, Princeton University Library, Berkeley’s Bancroft Library, the Russell Archives at McMaster, the Archives of the Universities of Warsaw and Wittenberg-Halle, the ILLC, the Austrian National Library, the NSUB at Göttingen, the National Portrait Gallery, the Oslo Museum, Neil Reid (Julia Robinson’s brother-in-law), Libby Marcus (Ruth Barcan Marcus’s daughter), Kim Heffernan (Haskell Curry’s granddaughter), Eckhardt Menzler-Trott, Craig Smorynski, and Peter van Emde Boas. Detailed photo credits are included with the photos. Thanks also to the Alberta OER
initiative for providing some funding to do this. And last, but not least, thanks to Joel Fuller
for doing an awesome job with PhotoShop restoring some of these photos (the original Curry photo, in particular, had a big tear right through the middle)!
More to come!
An article just published in Quanta Magazine by Natalie Wolchover covers a recent result from reverse mathematics. Keita Yokoyama and Ludovic Patey showed that Ramsey’s theorem for pairs is finitistically reducible, i.e., it is \(\Pi_3\) conservative over \(I\Sigma_1\). The article explains Ramsey’s theorem, but also Hilbert’s program and its more recent relativizations, i.e., the reverse mathematics program.

In the course of the last century, different general frameworks for the foundations of mathematics have been investigated. The orthodox approach to foundations interprets mathematics in the universe of sets. More recently, however, there have been other developments that call into question the whole method of set theory as a foundational discipline. Category-theoretic methods that focus on structural relationships and structure-preserving mappings between mathematical objects, rather than on the objects themselves, have been in play since the early 1960s. But in the last few years they have found clarification and expression through the development of homotopy type theory. This represents a fascinating development in the philosophy of mathematics, where category-theoretic structural methods are combined with type theory to produce a foundation that accounts for the structural aspects of mathematical practice. We are now at a point where the notion of mathematical structure can be elucidated more clearly and its role in the foundations of mathematics can be explored more fruitfully.
The main objective of the conference is to reevaluate the different perspectives on mathematical structuralism in the foundations of mathematics and in mathematical practice. To do this, the conference will explore the following research questions: Does mathematical structuralism offer a philosophically viable foundation for modern mathematics? What role do key notions such as structural abstraction, invariance, dependence, or structural identity play in the different theories of structuralism? To what degree does mathematical structuralism as a philosophical position describe actual mathematical practice? Does category theory or homotopy type theory provide a fully structural account for mathematics?

My friend and colleague Helmut Veith died yesterday. His death is a great and shocking loss to his family and friends, and the logic community, especially in Austria.
I’ve known Helmut since we were undergraduates in computer science at Vienna Technical University in the early 1990s. We shared a passion for theoretical topics in computer science, a love of Robert Musil; we took many courses together. In fact, we liked logic so much that together we created a specialized course of study (a studium irregulare) in computational logic. At the time this still required approval by the federal ministry of science and research, and it was a lot of work, but we got it approved. It has since morphed into a standard stream in the computer science curriculum at the TU Vienna, and more recently a doctoral program, all in no small part due to Helmut’s tireless organizational work. I was a year ahead of him, but he was the better student. He literally had straight As throughout high school and university. In Austria, that earns you a doctorate sub auspiciis praesidentis, and the president of the republic himself hands you your diploma. His Diplom was on finite model theory; his dissertation on the complexity of database query languages (supervised by Georg Gottlob). Helmut had a stellar career: appointments at TU Munich, TU Darmstadt (two of the centers of computer science in Germany), and finally a full professorship at our alma mater in 2010; add to that an adjunct professorship at Carnegie Mellon. Not only was he the better student, he had the better sense to stay in computer science, and to do something useful with logic. He was one of the leading experts in computer aided verification, especially model checking, with over 120 papers to his name. After his return to Vienna, he was instrumental in getting the Vienna Center for Logic and Algorithms off the ground, led the organization of the Vienna Summer of Logic, and helmed the Austrian doctoral program on logical methods in computer science. Helmut wasn’t just an outstanding researcher, he was also passionate about improving undergraduate education in logic and computer science (he served on the ASL’s Logic Education committee, and we co-organized a special session at the 2014 Logic Colloquium), about diversity in the field, and about science policy.
We need more people like him. I miss him.
