Scientists and Society face the ethical challenges of computational science together. The 3rd Heidelberg Laureate Forum (HLF) hosted a multi-faceted discussion riveted on Big Data and resolving challenges produced by computational science. The Hot Topic, ‘Brave New Data World’, was broken down into presentations from leading authorities, moderated workshops and an open debate among the participants. The Heidelberg Laureate Forum Foundation (HLFF) strives to create the opportunity for progressive discourse to flourish, which is most effectively championed by the conglomeration of diverse mindsets. The Hot Topic dove into enigmatic questions that are woven throughout computational science. How secure is our data? How is intellectual property evolving? Should we blindly accept massive data mining? How is computational science most effectively used for good? How should we regulate this ‘brave new data world’? Set to address these issues were: Alessandro Acquisti of Carnegie Mellon University, Kristin Tolle of Microsoft Research Outreach and Jeremy Gillula of the Electronic Frontier Foundation. The Hot Topic was coordinated by Michele Catanzaro, author of “Networks: A Very Short Introduction” and a highly accomplished freelance science journalist. Michele saw the 3rd HLF as an ideal environment and “fertile ground for making scientists provocative and constructive allies to the public”.

Background The Heidelberg Laureate Forum Foundation (HLFF) annually organizes the Heidelberg Laureate Forum (HLF), which is a networking event for mathematicians and computer scientists from all over the world. The 4th Heidelberg Laureate Forum will take place from September 18 to 23, 2016. The HLF was initiated by the German foundation Klaus Tschira Stiftung (KTS), which promotes natural sciences, mathematics and computer science, and the Heidelberg Institute for Theoretical Studies (HITS). The Forum is organized by the HLFF in cooperation with KTS and HITS as well as the Association for Computing Machinery (ACM), the International Mathematical Union (IMU), and the Norwegian Academy of Science and Letters (DNVA). www.heidelberg-laureate-forum.org
