# Paintings Reveal Signs Of Alzheimer's And Parkinson's In Famous Artists

Researchers from the University of Liverpool have shown that it's possible to detect neurodegenerative disorders in famous artists by analysing subtle changes in their brush strokes over time. The technique could eventually be used to flag Alzheimer's and Parkinson's in artists before they're diagnosed.

# The Twisted Logic Behind Why Airlines Sell Too Many Tickets

Each year, tens of thousands of passengers get bumped from their scheduled flights because of overbooking. A new video from TED-Ed explains why companies do it, and why you have a right to be pissed off when it happens.

# These Are The Four Stages Of Your Brain On Maths

Have you ever wondered what your brain is really doing as you sweat your way through a maths test? Now you can see for yourself, thanks to a new brain imaging study from Carnegie Mellon University that captured the brain activity of people in the act of solving maths problems.

# This Man's Explanation On The Way We Eat Pizza Is 'Remarkable'

If you fold a pizza in half lengthwise to eat it (the proper way to eat pizza), then you're actually utilising mathematician Carl Gauss's "theorem egregium" or the "remarkable theorem".

# Playing Super Mario Brothers Is Like Solving A Super Hard Maths Problem

If you've ever been frustrated at your inability to complete a level of Super Mario Brothers, here's a little something to cheer you up. Computer scientists have demonstrated that solving a level in the popular video game is tantamount to solving some of the hardest problems in computational science.

# We've Finally Solved The Mystery Of How Monarch Butterflies Navigate Thousands Of Kilometres

Each year, the migratory monarch butterfly embarks on an extraordinary journey from eastern North America to central Mexico. A multidisciplinary team of scientists has now created a model circuit that finally explains how these insects are able to navigate across such vast distances.

# Vintage Mechanical Calculator Shows Why It's A Bad Idea To Divide By Zero

Everyone learns in primary school that you can't divide by zero, but few of us ever learn (or fully understand) why. The stock answer is that it gives you an answer of infinity. The truth is a bit more nuanced than that, and an old mechanical calculator offers the perfect illustration.

# Does Infinity Really Exist?

Our universe appears to be bound by a finite set of laws, yet we often talk about things that go on for an eternity. "Infinity" is a strange idea. But it's crucial if you want to understand anything from philosophy to mathematics. Here's why.

# This Fractal Generator Is More Beautiful Than The Hypnotic Patterns It Creates

Designer Love Hultén is probably best known for his Pixel Vision, a tiny portable gaming machine made of wood that's reminiscent of the folding Game Boy Advance. His latest creation doesn't play games, but it does generate mesmerising fractals guaranteed to burn hours of time.

# Science Seems Like Magic As This Spilled Couscous Perfectly Organizes Itself

Video: Science presenter Steve Mould used a simple bow to demonstrate how when played like a violin, a metal plate will resonate and cause a bunch of spilled couscous to beautifully align into what are known as Chladni figures.

# This Babylonian Astronomy Text Changes History

More than a thousand years before the first telescopes, Babylonian astronomers tracked the motion of planets across the night sky using simple arithmetic. But a newly translated text reveals that these ancient stargazers also used a far more advanced method, one that foreshadows the development of calculus over a thousand years later.

# Fractal Analysis Proves People Hate The Suburbs

A new fractal analysis of London's dense network of streets and intersections reveals that a green belt meant to encourage migration to the suburbs had the opposite effect. The city has just became denser. People really seem to love urban living, especially in a thriving city like London. The work could shed light on how modern cities evolve, and help guide future urban growth policies.

# Meet The 2016 Winners Of The \$700,000 Crafoord Prize

The Royal Swedish Academy of Sciences has awarded its prestigious Crafoord Prize, honouring three scientists who have made outstanding achievements in black hole physics and a special kind of geometry.

# Fractals Make This Simple Nine Piece Puzzle A Nightmare To Solve

The complexity of a puzzle is usually dependent on how many tiny pieces are crammed inside its box. But by introducing mathematical fractals into the design, this plain nine-piece puzzle by Oscar van Deventer looks like a nightmare to solve.

# The First Mathematical Theory On Why There Are So Many Fricking Men

Men, am I right? They're everywhere. But why are there so many of them?

# No, This Viral Image Does Not Explain The History Of Arabic Numerals

Your cousin's Facebook friends are probably going nuts over this image that claims to show how the early history of Arabic geometric design informs how we write numerals today. "Each figure contains its own number of corners and angles," reads the text. That's half-true of the drawings in the image. The rest is patently false.

# Why Mathematicians Are Hoarding This Special Type Of Japanese Chalk

Earlier this year, an 80-year-old Japanese chalk company went out of business. Nobody, perhaps, was as sad to see the company go as mathematicians who had become obsessed with Hagoromo Fulltouch Chalk, the so-called "Rolls Royce of chalk".

# Did You Know You Can Subtract Large Numbers By Adding Them?

Video: The MinutePhysics series has always been a goldmine of interesting facts and science explainers. But prepare to have your mind blown wide open this time as Henry Reich shows you an alternate way to manually subtract large numbers — by doing addition instead.

# Singapore's Prime Minister Has Published His Own C++ Sudoku Solver

Everyone needs a hobby. For Lee Hsien Loon, that happens to be writing C++ Sudoku solvers and publishing them on the internet. Lee Hsien Loong also happens to be the Prime Minister of Singapore.

# The Golden Ratio Is A Lie

The Golden Ratio is the secret, silver bullet for refined design and balanced aesthetics. It's on display in great works of art like the Mona Lisa. Even the Apple logo leans on the Golden Ratio for mathematical order. At least that's what you've been told. FastCo Design's John Brownlee has news for you though: "It's bullshit."
