Illusive patterns in math explained by ideas in physics
Patterns appear widely throughout nature and math, from the Fibonacci spirals of
sea shells to the periodicity of crystals. But certain math problems can sometimes
trick the human solver into seeing a pattern, but then, out of the blue, the pattern suddenly disappears.

NWC September Math Links: Prime Numbers and The Riemann Hypothesis, by
Barry Mazur and William Stein
"This book is a soaring ride, starting from the simplest ideas and ending with one of the deepest unsolved problems of mathematics. Unlike in many popular math books puffed up with anecdotal material, the authors here treat the reader as seriously interested in prime numbers and build up the real math in four stages with compelling graphical demonstrations revealing in deeper and deeper ways the hidden music of the primes. If you have ever wondered why so many mathematicians are obsessed with primes, here's the real deal."

Generalized Hardy's paradox shows an even stronger conflict between quantum and classical physics
In 1993, physicist Lucien Hardy proposed an experiment showing that there is a small probability (around 6-9 percent)
of observing a particle and its antiparticle interacting with each other without annihilating - something that
is impossible in classical physics. The way to explain this result is to require quantum theory to be nonlocal:
that is, to allow for the existence of long-range quantum correlations, such as entanglement, so that particles
can influence each other across long distances.

Researchers prove Huygens was right about pendulum synchronization
In 1665 Christiaan Huygens discovered that two pendulum clocks, hung from the same wooden structure, will always oscillate in synchronicity.
Today, some 350 years on, Eindhoven and Mexican researchers present the most accurate and detailed description of this 'Huygens synchronization'
to date in the journal Scientific Reports.
The moon thought to play a major role in maintaining Earth's magnetic field
The Earth's magnetic field permanently protects us from the charged particles and radiation that originate in the sun. This shield is produced by the geodynamo,
the rapid motion of huge quantities of liquid iron alloy in the Earth's outer core. To maintain this magnetic field until the present day, the classical model
required the Earth's core to have cooled by around 3,000 C over the past 4.3 billion years. Now, a team of researchers from CNRS and Universite Blaise Pascal1
suggests that, on the contrary, its temperature has fallen by only 300 C. The action of the moon, overlooked until now, is thought to have compensated for this
difference and kept the geodynamo active. Their work is published on 30 march 2016 in the journal Earth and Planetary Science Letters.

UMD Researchers Build a Smaller Device to Pick up Bigger Noises
Researchers, Radu Balan of the NWC, Justinian Rosca, of Siemens Corporate Technology, and Mark Lai (PhD, UMD), of UT Austin, build a smaller device
to pick up bigger noises.
"Imagine being able to stand in the middle of a loud party or an airport with hundreds of people, and selectively single out voices that you need to
analyze for security reasons. At the other extreme, imagine you are in a factory with many noisy machines running, and you can actually single out
the noise from a specific device you are interested in..."
Blooms: Strobe-Animated Sculptures
These are 3-D printed sculptures designed by John Edmark to animate when spun under a strobe light.
The placement of the appendages is determined by the same method nature uses in pinecones and sunflowers.
The rotation speed is synchronized to the strobe so that one flash occurs every time the sculpture turns
137.5 degrees (the golden angle). If you count the number of spirals on any of these sculptures you will find
that they are always Fibonacci numbers.

Multiple Authors Detection: A Quantitative Analysis of Dream of the Red Chamber
From the abstract "Inspired by the authorship controversy of Dream of the Red Chamber and the application of machine learning in the study of
literary stylometry, we develop a rigorous new method for the mathematical analysis of authorship by testing for a so-called chrono-divide in writing styles...
Applying our method to the Cheng-Gao version of Dream of the Red Chamber has led to convincing if not irrefutable evidence that the first 80 chapters and the
last 40 chapters of the book were written by two different authors."

The father of the World Cup hero, Mario Goetze, worked on wavelets.
In 1995 and '96, Mario's dad, Jurgen Goetze, was a postdoc researcher at Rice's electrical engineering department. While here, he co-authored papers such as "Approximate Moments and Regularity of Efficiently Implemented Orthogonal Wavelet Transforms" and "Parameterization of Orthonormal Wavelet Transforms and Their Implementation."

An Illustration of the Loss of Data Due to Repeated
"Every time you upload... their video servers will re-encode it again.
Encoding the video means that it will be compressed, taking details out of
the image and audio, and producing artifacts. When you do this once, the details
and the artifacts are not noticeable.... The problem occurs when you go through
this process many times. The artifacts and lack of detail get fed again to
the compressor, which takes out even more details and introduces new glitches.
The second time you do it, you probably won't notice it. But every time this
process is repeated, more will go off.
