Obituary: Amir Pnueli, 1941–2009 Krzysztof R. Apt and Lenore D. Zuck
Obituary: Amir Pnueli, 1941–2009 Krzysztof R. Apt and Lenore D. Zuck Amir Pnueli was born in Nahalal, Israel, on April 22, 1941 and passed away in New York City on November 2, 2009 as a result of a brain hemorrhage. Amir founded the computer science department in Tel-Aviv University in 1973. In 1981 he joined the department of mathematical sciences at the Weiz- mann Institute of Science, where he spent most of his career and where he held the Estrin family chair. In recent years, Amir was a faculty member at New York University where he was a NYU Silver Professor. Throughout his career, in spite of an impressive list of achievements, Amir remained an extremely modest and selfless researcher. His unique combination of excellence and integrity has set the tone in the large community of researchers working on specification and verification of programs and systems, program semantics and automata theory. Amir was devoid of any arrogance and those who knew him as a young promising researcher were struck how he maintained his modesty throughout his career. Amir has been an active and extremely hard working researcher till the last moment. His sudden death left those who knew him in a state of shock and disbelief. For his achievements Amir received the 1996 ACM Turing Award. The citation reads: “For seminal work introducing temporal logic into computing science and for outstanding contributions to program and system verification.” Amir also received, for his contributions, the 2000 Israel Award in the area of exact sciences. More recently, in 2007, he shared the ACM Software System Award. -

The Advent of Recursion & Logic in Computer Science
The Advent of Recursion & Logic in Computer Science MSc Thesis (Afstudeerscriptie) written by Karel Van Oudheusden –alias Edgar G. Daylight (born October 21st, 1977 in Antwerpen, Belgium) under the supervision of Dr Gerard Alberts, and submitted to the Board of Examiners in partial fulfillment of the requirements for the degree of MSc in Logic at the Universiteit van Amsterdam. Date of the public defense: Members of the Thesis Committee: November 17, 2009 Dr Gerard Alberts Prof Dr Krzysztof Apt Prof Dr Dick de Jongh Prof Dr Benedikt Löwe Dr Elizabeth de Mol Dr Leen Torenvliet 1 “We are reaching the stage of development where each new gener- ation of participants is unaware both of their overall technological ancestry and the history of the development of their speciality, and have no past to build upon.” J.A.N. Lee in 1996 [73, p.54] “To many of our colleagues, history is only the study of an irrele- vant past, with no redeeming modern value –a subject without useful scholarship.” J.A.N. Lee [73, p.55] “[E]ven when we can't know the answers, it is important to see the questions. They too form part of our understanding. If you cannot answer them now, you can alert future historians to them.” M.S. Mahoney [76, p.832] “Only do what only you can do.” E.W. Dijkstra [103, p.9] 2 Abstract The history of computer science can be viewed from a number of disciplinary perspectives, ranging from electrical engineering to linguistics. As stressed by the historian Michael Mahoney, different `communities of computing' had their own views towards what could be accomplished with a programmable comput- ing machine. -
Alfred Tarski and a Watershed Meeting in Logic: Cornell, 1957 Solomon Feferman1
Alfred Tarski and a watershed meeting in logic: Cornell, 1957 Solomon Feferman1 For Jan Wolenski, on the occasion of his 60th birthday2 In the summer of 1957 at Cornell University the first of a cavalcade of large-scale meetings partially or completely devoted to logic took place--the five-week long Summer Institute for Symbolic Logic. That meeting turned out to be a watershed event in the development of logic: it was unique in bringing together for such an extended period researchers at every level in all parts of the subject, and the synergetic connections established there would thenceforth change the face of mathematical logic both qualitatively and quantitatively. Prior to the Cornell meeting there had been nothing remotely like it for logicians. Previously, with the growing importance in the twentieth century of their subject both in mathematics and philosophy, it had been natural for many of the broadly representative meetings of mathematicians and of philosophers to include lectures by logicians or even have special sections devoted to logic. Only with the establishment of the Association for Symbolic Logic in 1936 did logicians begin to meet regularly by themselves, but until the 1950s these occasions were usually relatively short in duration, never more than a day or two. Alfred Tarski was one of the principal organizers of the Cornell institute and of some of the major meetings to follow on its heels. Before the outbreak of World War II, outside of Poland Tarski had primarily been involved in several Unity of Science Congresses, including the first, in Paris in 1935, and the fifth, at Harvard in September, 1939. -

Alan Turing was a brilliant original thinker. He made original and lasting contributions to several fields, from theoretical computer science to artificial intelligence, cryptography, biology, philosophy etc. He is generally considered as the father of theoretical computer science and artificial intelligence. His brilliant career came to a tragic and untimely end in June 1954. In 1945 Turing was awarded the O.B.E. for his vital contribution to the war effort. In 1951 Turing was elected a Fellow of the Royal Society. -

The Best Nurturers in Computer Science Research
The Best Nurturers in Computer Science Research Bharath Kumar M. Y. N. Srikant IISc-CSA-TR-2004-10 http://archive.csa.iisc.ernet.in/TR/2004/10/ Computer Science and Automation Indian Institute of Science, India October 2004 The Best Nurturers in Computer Science Research Bharath Kumar M.∗ Y. N. Srikant† Abstract The paper presents a heuristic for mining nurturers in temporally organized collaboration networks: people who facilitate the growth and success of the young ones. Specifically, this heuristic is applied to the computer science bibliographic data to find the best nurturers in computer science research. The measure of success is parameterized, and the paper demonstrates experiments and results with publication count and citations as success metrics. Rather than just the nurturer’s success, the heuristic captures the influence he has had in the indepen- dent success of the relatively young in the network. These results can hence be a useful resource to graduate students and post-doctoral can- didates. The heuristic is extended to accurately yield ranked nurturers inside a particular time period. Interestingly, there is a recognizable deviation between the rankings of the most successful researchers and the best nurturers, which although is obvious from a social perspective has not been statistically demonstrated. Keywords: Social Network Analysis, Bibliometrics, Temporal Data Mining. 1 Introduction Consider a student Arjun, who has finished his under-graduate degree in Computer Science, and is seeking a PhD degree followed by a successful career in Computer Science research. How does he choose his research advisor? He has the following options with him: 1. Look up the rankings of various universities [1], and apply to any “rea- sonably good” professor in any of the top universities. -

ABSTRACT (Maxrmum 200 words) Abstract. It has been repeatedly observed that the standard safety-liveness classification of properties of reactive systems does not fit for real-time proper- ties. This is because the implicit “liveness” of time shifts the spectrum towards the safety side. While, for example, response - that “something good” will happen, eventually - is a classical liveness property, bounded response - that “something good” will happen soon, within a certain amount of time - has many characteristics of safety.
