Question: What professor of mathematics authored the book Fashionable Nonsense?

Context paragraphs:
Fashionable Nonsense: Fashionable Nonsense: Postmodern Intellectuals' Abuse of Science (French: "Impostures Intellectuelles" ), published in the UK as Intellectual Impostures, is a book by physicists Alan Sokal and Jean Bricmont.  Sokal is best known for the Sokal Affair, in which he submitted a deliberately absurd article to "Social Text", a critical theory journal, and was able to get it published.

Nairi Sedrakyan: Nairi Sedrakyan (born 1961 in Ninotsminda, USSR) is an Armenian mathematician involved in national and international Olympiads of mathematics, having been the president of Armenian Mathematics Olympiads, the Leader of Armenian IMO Team, jury member and problem selection committee member of International Mathematical Olympiad, jury member and problem selection committee member of Zhautykov International Mathematical Olympiad (ZIMO), jury member and problem selection committee member of the 1st International Olympiad of Metropolises, the president of International Mathematical Olympiad Tournament of the Towns in Armenia.  He has also authored a large number of problems proposed in these Olympiads.  Nairi Sedrakyan is the author of one of the hardest problems ever proposed in the history of International Mathematical Olympiad, 5th problem of 37th International Mathematical Olympiad.  This problem is considered as one of the hardest problems ever, because none of the members of the strongest teams, i.e. National Olympic Teams of the USA, Russia or China has succeeded to solve it correctly.  Moreover, the National Olympic Team of People's Republic of China has obtained a cumulative result equal to 0 points and was ranked the 6th in the final ranking of the countries instead of the usual 1st or 2nd place.  The British 2014 film X+Y, released in the USA as A Brilliant Young Mind, inspired by, Beautiful Young Minds focuses on an English mathematical genius chosen to represent the United Kingdom at the IMO.  In the film this problem is stated to be the hardest problem ever proposed in the history of International Mathematical Olympiad (minutes 9:40-10:30).  Other outstanding results of the author are having 4 problems in the Shortlist of the worldwide selected 27 problems of the 40th IMO (1999) in Romania and having 5 medals winner students in 41st IMO in South Korea, i.e. 2 silver medals and 3 bronze medals.  Moreover, only 1 point was missing for Sevak Mkrtchyan to obtain a Gold Medal (currently he is an assistant professor of mathematics in United States, Sevak received his PhD in mathematics from University of California, Berkley).  Nevertheless, Arthur Barkhoudarian, one of the first students of Nairi Sedrakyan has received a Gold Medal in International Mathematical Olympiad, later on Arthur received his PhD degree in mathematics from Charles University in Prague.  As all winner students were from the same school, where Nairi Sedrakyan was teaching mathematics, the government of the Republic of Armenia gave to the author the title of the best teacher of the Republic of Armenia and he received a special gift from the Prime Minister.

Alan Sokal: Alan David Sokal ( ; born January 24, 1955) is a professor of mathematics at University College London and professor of physics at New York University.  He works in statistical mechanics and combinatorics.  He is best known to the wider public for his criticism of postmodernism, after the Sokal affair in 1996 when his deliberately nonsensical paper was published by Duke University's "Social Text".  He also works to counter faulty scientific reasoning, as seen with his involvement in criticising the critical positivity ratio concept in positive psychology.

Titu Andreescu: Titu Andreescu (born 1956) is an associate professor of mathematics at the University of Texas at Dallas.  He is also firmly involved in mathematics contests and olympiads, having been the Director of AMC (as appointed by the Mathematical Association of America ), Director of MOP, Head Coach of the USA IMO Team and Chairman of the USAMO.  He has also authored a large number of books on the topic of problem solving and olympiad style mathematics.

Mark Steiner: Mark Steiner (born May 6, 1942) is a professor of philosophy at the Hebrew University of Jerusalem, where he specializes in the philosophy of mathematics and physics.  He is best known for his book "The Applicability of Mathematics as a Philosophical Problem", in which he attempted to explain the historical utility of mathematics in physics.  The book may be considered an extended meditation on the issues raised by Eugene Wigner's article "The Unreasonable Effectiveness of Mathematics in the Natural Sciences" .  The publisher writes, "Steiner argues that, on the contrary, these laws were discovered, using manmade mathematical analogies, resulting in an anthropocentric picture of the universe as "user friendly" to human cognition—a challenge to the entrenched dogma of naturalism."  Steiner is also the author of the book "Mathematical Knowledge".

Angus Ellis Taylor: Angus Ellis Taylor (October 13, 1911 – April 6, 1999) was a mathematician and professor at various universities in the University of California system.  He earned his undergraduate degree at Harvard "summa cum laude" in 1933 and his PhD at Caltech in 1936 under Aristotle Michal with a dissertation on analytic functions. By 1944 he had risen to full professor at UCLA, whose mathematics department he later chaired (1958–1964).  Taylor was also an astute administrator and eventually rose through the UC system to become provost and then chancellor of UC Santa Cruz.  He authored a number of mathematical texts, one of which, "Advanced Calculus" (1955, Ginn and Co.), became a standard for a generation of mathematics students.

Ruchir Puri: Ruchir Puri is the chief architect of IBM Watson, responsible for developing and deploying Watson platform architecture across the range of Watson offerings.  He is an IBM Fellow at IBM Thomas J Watson Research Center, Yorktown Heights, New York.  In the past, Ruchir has led the Deep Learning and Machine Learning Platform Initiative at IBM Research to advance IBM’s cognitive cloud platform vision and also led IBM's efforts in software-hardware acceleration for cognitive and analytic workloads and driven strategy for differentiated cognitive computing infrastructure.  Puri has received numerous accolades including the highest technical position at IBM, the IBM Fellow, which was awarded for his transformational role in microprocessor design methodology.  In addition, Puri has received “Best of IBM” awards in both 2011 and 2012 and IBM Corporate Award from IBM’s CEO, and several IBM Outstanding Technical Achievement awards.  Puri is a Fellow of the IEEE, a member of IBM Academy of Technology and IBM Master Inventor, an ACM Distinguished Speaker and IEEE Distinguished Lecturer.  He is a recipient of SRC's outstanding mentor award and has been a visiting faculty member at the Dept. of Computer Science, Stanford University, CA, and an adjunct professor at the Dept. of Electrical Engineering, Columbia University, NY and was also honored with John Von-Neumann Chair at Institute of Discrete Mathematics at Bonn University, Germany.  Ruchir received the 2014 Asian American Engineer of the Year Award.  He has delivered numerous keynotes and invited talks at major software and hardware conferences, National Science Foundation and US Department of Defense Research panels and has been an editor of IEEE Transactions on Circuits and Systems.  Puri is an inventor of over 50 United States patents (both issued and pending) and has authored over 100 publications as well as authored a book on Analyzing Analytics.  Ruchir is very passionate about technology among school children and has been evangelizing fun with electronics and FIRST LEGO LEAGUE Robotics in community schools.

P. K. Srinivasan: P.K. Srinivasan (PKS) (November 4, 1924 – June 20, 2005) was a well known mathematics teacher in India.  He taught mathematics at the Muthialpet High School in Chennai, India until his retirement.  His singular dedication to education of mathematics would bring him to the United States, where he worked for a year, and then to Nigeria, where he would work for six years.  He is known in India for his dedication to teaching mathematics and in creating pioneering awareness of the Indian mathematician Ramanujan.  He has authored several books in English, Telugu and Tamil that introduce mathematics to children in novel and interesting ways.  He was also a prominent reviewer of math books in the weekly "Book Review" column of the Indian newspaper The Hindu in Chennai.
