We have all seen interesting patterns of tiling the plane with interlocking shapes, known as a tessellation. The process of producing a complete inventory of all possible tessellation has resisted solution for over a century, until now.
The honor goes to Michael Rao of the Ecole Normale Superieure de Lyon in France. He has completed a computerassisted proof to complete the inventory of pentagonal shapes, the last remaining holdout. He identified 371 scenarios for how corners of pentagons might fit together, and then checked, by means of an algorithm, each scenario. In the end, his computer program determined that the

The Abel Prize
On 21 March 2017 the Norwegian Academy of Science and Letters announced that the 2017 Abel Prize for mathematics, thought by many to be on a par with the Nobel Prize, has been awarded to Yves Meyer for his groundbreaking work on wavelets.
Many of the leading awards made in the field of mathematics are for highly abstract theoretical work. But wavelet theory is certainly in the area of applied mathematics, as it is now used in many different realworld arenas. Applications include data compression, acoustic noise

Victoria Stodden, Marcia McNutt (President of the American Association for the Advancement of Science), David H. Bailey, Ewa Deelman, Yolanda Gil, Brooks Hanson, Michael Heroux, John Ioannidis and Michela Taufer have published an article in Science (the principal journal of the AAAS) entitled Enhancing reproducibility in computational methods.
In this article we argue that the field of mathematical and scientific computing lags behind other fields in establishing a culture and tools to ensure reproducibility. All too often, the authors of computations, even those that are published in peerreviewed conferences and journals, have not fully documented their algorithms, code, input data

The Breakthrough Foundation has announced a new set of winners of their awards, including recipients in mathematics, physics and life sciences. The founders of the Breakthrough Prize are Sergey Brin (cofounder of Google) and Anne Wojcicki (cofounder of 23andme), Mark Zuckerberg and Priscilla Chan (founder of Facebook and his spouse), Yuri Milner and Julia Milner (Russian venture capitalist and his spouse), and Jack Ma and Cathy Zhang (founder of Alibaba and his spouse).
Mathematics prize
The Breakthrough Prize in mathematics (USD$3 million) was awarded to Jean Bourgain of the Institute for Advanced Study in Princeton, New Jersey. Bourgain’s work

The American Mathematical Society has announced that David H. Bailey, Jonathan Borwein, Andrew Mattingly and Glenn Wightwick will receive the 2017 Levi L. Conant Prize. Bailey is a retired senior scientist at the Lawrence Berkeley National Laboratory, and a research associate at the University of California, Davis. Borwein (deceased 2 August 2016) was a Laureate Professor of Mathematics at the University of Newcastle, Australia. Mattingly is senior information technology architect at IBM Australia. Wightwick is deputy vicechancellor and vicepresident (Research) at the University of Technology Sydney.
This year’s prize was awarded for the recipients’ 2013 article The Computation of Previously

It is my sad duty to report that our colleague Jonathan Borwein, Laureate Professor of Mathematics at the University of Newcastle, Australia, has passed away at the age of 65. He is survived by his wife Judith and three daughters. For details on his funeral and for making donations to a scholarship fund in his name, see the obituary below.
Jonathan M. Borwein
What can one say about Jon’s professional accomplishments? Adjectives such as “profound,” “vast” and “farranging” don’t really do justice to his work, the sheer volume of which is astounding: 388 published journal articles, plus another 103
