Quotations about data analysis
"The traditional rationale within applied mathematics has been to solve
or provide insight for equations which describe some part of the
physical world. .... But there is a paradigm shift afoot. Mathematics
is used to describe data, without the benefit of an interpolating
equation or physical principle."
(J. Glimm, Bulletin of the American Mathematical Society, 47, Jan
2010, p. 127136.)
"The analysis of large data sets to provide understanding, and
ultimately knowledge, is one of the fundamental
intellectual challenges of our time. It falls to
practitioners of the mathematical sciences
(mathematics, statistics, and computer science) to
devise new methods for carrying out analysis tasks,
as well as to construct new models or paradigms for
thinking about data."
(Gunnar Carlsson and Robert Ghrist, SIAM News, April 2012).
