Celebrating 10 years of the HLF, these are short, rapid-fire, one-slide talks that look back at the last 10 years in computer science and mathematics, or even risk a glimpse into the future. These range from an important breakthrough of the last 10 years, a challenge or problem for the future, or a piece of advice to attending young researchers. Moderator: Tom Crawford John E. Hopcroft: A Road to a Successful Career Shigefumi Mori: Rational Curves on Algebraic Varieties Butler W. Lampson: Safety of IoT Madhu Sudan: Reliability in Cumulative Knowledge Vinton Gray Cerf: Interplanetary Internet Joseph Sifakis: Testing System Intelligence Eric A. Brewer: Open Source is a Public Good Daniel Spielman: Computer Experiments for Computer Science and Mathematics Martin Hellman: Friends Are Better than Enemies Alexei Efros: Advances in Visual Computing The 10th Heidelberg Laureate Forum took place from September 24–29, 2023. #HLF23 The Heidelberg Laureate Forum (HLF) is an annual networking conference where 200 carefully selected young researchers in mathematics and computer science spend a week interacting with the laureates of the most prestigious awards in their disciplines: the Abel Prize, ACM A.M. Turing Award, ACM Prize in Computing, Fields Medal, IMU Abacus Medal and Nevanlinna Prize.
