Freely accessible books






Recently I prepared some of my books for free access on the Web (after gaining agreement from the publishers). Here are the corresponding links. They actually point to pages that present the respective books and have further links to the actual PDF versions. Although the texts are essentially those of the books as published, I … Read more




A remarkable group photo






On 13-15 September 1999 a symposium took place in St Catherine College in Oxford,  in honor of Tony Hoare’s “retirement” from Oxford (the word is in quotes because he has had several further productive careers since).
