Monday, August 20, 17:00 – 17:50 h, H 1012
Horst Zuse: The origins of the computer
Chair: Martin Grötschel
Abstract:
Many outstanding scientists and managers were necessary to get the computer to the point of development that we know today. Konrad Zuse (19101995) is almost unanimously accepted as the inventor of the first working, freely programmable machine using Boolean logic and binary floating point numbers. This Machine  called Z3  was finished by Konrad Zuse in May 1941 in his small workshop in BerlinKreuzberg. In this presentation the achievements of Charles Babbage (1823), the development of the secret COLOSSUSProject (UK, 1943), Howard Aiken’s Mark I (USA), and the ENIAC (USA) are outlined. Konrad Zuse’s contributions to computer development are presented, of course, as well, with many surprising pictures and videos. It is not well known, that Konrad Zuse founded, in 1949, a computer company that produced 251 computers of a value of 51 Million Euros. It was the first company which produced computers in a commercial way.
Biographical sketch: Horst Zuse, the oldest of Konrad Zuse’s five children, was born on November 17, 1945 in Hindelang (Bavaria, Germany). He received his PhD degree in computer science from Technische Universität Berlin (TUB) in 1985. From 19752010 he was a senior research scientist at TUB. His research interests are information retrieval systems, software engineering, software metrics, computer history and computer architectures. In 1991 he published the book Software Complexity  Measures and Methods (De Gruyter Publisher). In 1998 the book A Framework for Software Measurement (De Gruyter Publisher) followed. In 1998 he received the habilitation (Privatdozent) in the area of Praktische Informatik (Practical Computer Science), and since 2006 he has been a Professor at the University of Applied Sciences in Senftenberg.

Eberhard Knobloch: Gottfried Wilhelm Leibniz – Universal genius and outstanding mathematician
Chair: Günter M. Ziegler
Abstract: The universal genius Gottfried Wilhelm Leibniz (16461716) contributed to nearly all scientific disciplines and left the incredibly huge amount of about 200,000 sheets of paper that are kept in the Leibniz Library of Hannover. About 4,000 of them regarding natural sciences, medicine, technology have been digitized and are freely available on the Internet: http://ritter.bbaw.de. Less than half of them have been published up to now. Hence we know for example  for the time being  only about one fourth of his mathematical production. The lecture will give a short survey of his biography and mainly deal with the following six aspects: 1. Leibniz as an organizer of scientific work: his presidency of the Berlin Academy of Sciences; 2. His rigorous foundation of infinitesimal geometry; 3. Leibniz as the inventor of the differential and integral calculus; 4. His conception of and his contributions to a general combinatorial art (symmetric functions, number theory, insurance calculus); 5. His proposals for engineering improvements in mining; 6. Leibniz's invention of the first real fourfunction calculating machine.
Biographical sketch: Eberhard Knobloch, born in 1943 in Görlitz, Germany, studied mathematics, classical philology, and history of science and technology at Freie Universität Berlin and Technische Universität Berlin. In 1972 he did a PhD in history of science and technology, in 1976 he passed the habilitation for university professors at Technische Universität Berlin. Since 2002 he is professor of history of science and technology at this university and Academy professor at the BerlinBrandenburg Academy of Sciences and Humanities (BBAW). He is a member of several national and international academies of sciences, president of the International Academy of the History of Science, past president of the European Society for the History of Science, Honorary professor of the Chinese Academy of Sciences. He published or edited more than 300 papers or books on the history of science and technology, he is a member of the editorial boards of sixteen international journals. His main scientific interests concern the history and philosophy of mathematical sciences and Renaissance technology. He is project leader of the A. v. Humboldt research group and the two Leibniz research groups at BBAW.

Günter M. Ziegler: Leonhard Euler: Three strikes of a genius
Chair: George Nemhauser
Abstract: We will explore three of Euler's genius contributions:  The seven bridges of Königsberg: How a problem of "Recreational Mathematics" led to the creation of Graph Theory.  The Basel problem: A healthy dose of serious numerical computing on the way to a zeta(2).  The polyhedron formula: Tracing the polyhedron formula from Stockholm to the Berne mountains.

Ziegler, born in München, Germany, in 1963, got a PhD at MIT in 1987, became a Professor of Mathematics at TU Berlin 1995, and moved to FU Berlin in 2011 as a MATHEON Professor. He became the founding chair of the Berlin Mathematical School in 2006. His interests connect discrete and computational geometry (especially polytopes), algebraic and topological methods in combinatorics, discrete mathematics and the theory of linear and integer programming.

Jürgen Sprekels: Karl Weierstrass and optimization
Chair: Richard Cottle
Abstract: The work of Karl Weierstrass, the outstanding Berlin mathematician who was one of leading mathematical researchers of the second half of the nineteenth century, had a deep impact on the theory of optimization and on variational calculus. In this talk, we review some aspects of his contributions to the field.
