The abiogenesis problem
Exactly how life first emerged on Earth (the “abiogenesis” problem) remains a critical unsolved question in biology. Was it inevitable, given a favorable environment, or was it a fantastically improbable event? All we know for sure is that it occurred at least 3.8 billion years ago and possibly more than 4 billion years ago. The fact that life arose relatively soon after the surface of the Earth solidified indicates to some that abiogenesis was inevitable, but there is no way to know for sure. For further

A pandemic is upon us
As this is being written (April 2020), the entire world is gripped in the throes of the rapidly spreading and deadly Covid19 pandemic. International travel has been greatly curtailed worldwide; many businesses, large and small, have shut their doors; many K12 schools and universities have closed; and entire regions and nations, encompassing well over one billion people, have been ordered to remain in their homes.
As of the current date (28 April 2020), the Johns Hopkins University Coronavirus Resource Center has tallied 3,062,000

We are happy to announce the publication of “From Analysis to Visualization: A Celebration of the Life and Legacy of Jonathan M. Borwein”, a compilation of research papers devoted to the memory of Jonathan Borwein. The book is the proceedings of a conference held in Borwein’s honor in September 2017 at Newcastle, Australia, near where Prof. Borwein taught for several years before passing away in August 2016.
The volume has been published by Springer, and is available for purchase from the Springer website, or from Amazon.com.
The individual papers are authored by many of Jonathan Borwein’s colleagues and collaborators. Here

An age of unparalleled progress
Though many do not recognize the fact, behind the disturbing headlines that dominate the news today, scientific progress marches forward, unabated and undiminished. Just within the past 100 years, researchers have discovered the theory of relativity, quantum mechanics and the standard model; unraveled the structure of DNA; sequenced the human genome; discovered the accelerating universe; observed extrasolar planets orbiting thousands of distant stars; and detected the collisions of black holes. See this Math Scholar article for additional details.
Spurred by these scientific advances, human technology has advanced at an astonishing pace: advances in medical

I have prepared a new paper containing a catalogue of 72 summation formulas, integral formulas and iterative algorithms for Pi. The catalogue contains both classical and modern formulas, ranging from Archimedes’ 2200yearold algorithm to intriguing formulas found by Ramanujan and the quadratic, cubic, quartic and nonic algorithms of Jonathan Borwein and Peter Borwein, the latter of which double, triple, quadruple and ninetimes, respectively, the number of correct digits with each iteration.
The catalogue of formulas and iterative algorithm is followed by results of carefully designed computer implementations, which enable one to compare the relative speed of these formulas.

Yes, it is that time of year — Pi Day (March 14, or 3/14 in North American month/day date notation) is here.
So in honor of the occasion, I have constructed a new crossword puzzle — see below. This puzzle honors several of the key persons through history who have made significant contributions to the theory and computation of Pi.
This puzzle conforms to the New York Times crossword conventions. As far as difficulty level, it would be comparable to the NYT Tuesday or Wednesday puzzles (the NYT puzzles are graded each week from Monday [easiest] to Saturday [most difficult]).

Introduction
A growing controversy over the multiverse and the anthropic principle has exposed a major fault line in modern physics and cosmology. Some researchers see the multiverse and the anthropic principle as inevitable, others see them as an abdication of empirical science. The controversy spans quantum mechanics, inflationary Big Bang cosmology, string theory, supersymmetry and, more generally, the proper roles of experimentation and mathematical theory in modern science.
The “many worlds interpretation” of quantum mechanics
Since the 1930s, when physicists first developed the mathematics behind quantum mechanics, researchers have found that this theory appears to

Introduction
Both traditional creationists and intelligent design writers have invoked probability arguments in criticisms of biological evolution. They argue that certain features of biology are so fantastically improbable that they could never have been produced by a purely natural, “random” process, even assuming the billions of years of history asserted by geologists and astronomers. They often equate the hypothesis of evolution to the absurd suggestion that monkeys randomly typing at a typewriter could compose a selection from the works of Shakepeare, or that an explosion in an aerospace equipment yard could produce a working 747 airliner [Dembski1998; Foster1991; Hoyle1981;

Factorization and cryptography
Until a few decades ago, number theory, namely the study of prime numbers, factorization and other features of the integers, was widely regarded as the epitome of pure mathematics, completely divorced from considerations of practical utility. This sentiment was expressed most memorably by British mathematician G.H. Hardy (best known for mentoring Ramanujan and results on the Riemann Zeta function), who wrote in his book A Mathematician’s Apology (1941),
I have never done anything “useful”. No discovery of mine has made, or is likely to make, directly or indirectly, for good

Gregory Zuckerman, author of The Greatest Trade Ever, has published a new book highlighting the life and work of Jim Simons, who, at the age of 40, walked away from a very successful career as a research mathematician and cryptologist to try his hand at the financial markets, and ultimately revolutionized the field. Zuckerman’s new book is titled The Man Who Solved the Market: How Jim Simons Launched the Quant Revolution.
Upbringing and academic career
Simons’ background hardly suggested that he would one day lead one of the most successful, if not the most successful, quantitative hedge fund operation in
