It is with great sadness that we announce that Joseph (Joe) Polchinski has died on February 2, 2018. Polchinski made fundamental contributions to Quantum Field Theory and String theory. Joe is best known for his discovery of D-branes – the key elements of string theory. For his many contributions to theoretical physics Joseph Polchinski has … Read more

The Selection Committee of the 2018 Sackler Prize in the physical sciences has decided to award the 2018 Sackler Prize in the field of “Quantum Field Theory (QFT) – Novel Developments and Applications” to Professor Zohar Komargodski from the Weizmann Institute, Israel and the Simons Center for Geometry and Physics, US, and to Professor Pedro … Read more
By George Sterman, Director of the C.N. Yang Institute for Theoretical Physics Most of us would agree that addition and subtraction are simpler than multiplication and division, at least for big numbers. And this is not just for people who lack an affinity for math. When quantitative astronomy began in earnest, astronomers like Tycho Brahe … Read more
By Kenji Fukaya Recently there has been a discussion among mathematicians, as well as in press and several blogs, covering the developments in symplectic geometry. Professor Fukaya expressed interest in giving his opinion and we are happy to present it here: The set of the solutions of the equation x2 + y2 – z2 = … Read more
By Simon Donaldson If we have four objects—say A, B, C, D—there are just three ways of dividing them into pairs: (AB)(CD) (AC)(BD) (AD)(BC). The salient property is that 3 is less than 4. This simple fact expresses something special about the number 4. For example if we take 6 objects there are 10 ways to divide … Read more
