Molecular footballs, knotty headphones and a naming contest for exoplanets

Is this exoplanet more of a Joanne than a Derek? You could soon be casting your vote to name 305 explanets

With the final two matches of the FIFA World Cup to look forward to this weekend, I thought I would sneak one more football-related story into the Red Folder. Over on the arXiv blog, there is a nice commentary about the topological nature of World Cup balls through the ages. Why? Well, two chemists in Taiwan have worked out a way to create a carbon-based molecule with the same shape as the football currently being used in the tournament in Brazil. Called the Brazuca, the ball is made from six panels that each have a four-leafed clover shape. Together, they form a structure with octahedral symmetry.

A network analysis of the FIFA World Cup

The FIFA World Cup is under way in Brazil as the national teams from 32 nations battle it out on the pitch for the most prestigious prize in football. It is also an exciting month for football fans across the world as everyone suddenly becomes an expert on the game. Offices, bars and cafes around the world echo with the sound of post-match analysis.

This post-match dissection has now been taken to another level by a pair of computer scientists at the University of Pisa in Italy. At the request of Physics World, Paolo Cintia and Luca Pappalardo have carried out a network analysis of the opening match of the tournament, which saw the hosts Brazil defeat Croatia by three goals to one. Cintia and Pappalardo have viewed the match as if it were an evolving network where players represent nodes that interact by passing the ball to each other along “edges”.

A day in the life of an astronaut, Hawking’s football conclusions, politics and science and more

For most of us, the life of an astronaut is one of excitement and adventure. Indeed, the mere thought of being a “real live astronaut” brings out the gleeful inner child in many, and photographer Tim Dodd is much the same. After purchasing a Russian high-altitude space suit from an online auction website, Dodd put together a series of photographs titled “A day in the life of Everyday Astronaut”, my favourite of which you can see above. Do take a look at the rest of the excellent series on Dodd’s website and follow him on Instagram for even more of the same.

Intelligent life on a doughnut, how cats and skiers spin, a marriage made at CERN and more

By Hamish Johnston

There’s definitely an educational vibe to this week’s picks from the Red Folder, which begins with Tanner Higgin’s selection of “Five apps that test your physics skills“. Writing on Mind/Shift, a website based in California and dedicated to learning, Higgin highlights Crayon Physics Deluxe, which allows users to draw physical objects and then let gravity and other physical effects take over. Also featured is Amazing Alex, which allows users to combine more than 30 different household objects to create fantastical Heath Robinson/Rube Goldberg contraptions.

Can Andy Murray give graphene a boost?

By Matin Durrani

Novak Djokovic uses a Head tennis racket containing graphene.

Novak Djokovic uses a Head tennis racket containing graphene.

It has become a cliché to call graphene the “wonder material” because of its incredible physical and electronic properties – this 2D honeycomb of carbon atoms is not only the strongest ever discovered, but also the stiffest, being able to sustain a current density a million times that of copper.

Having such great attributes is all well and good if you’re a researcher who’s fascinated by the subtleties of graphene’s electronic properties such as its lack of a band gap – but what if you’re a hard-nose business executive? Graphene will only be any good if it can help you to sell a product that’s somehow better than what’s already on the market and if it can at also make the company money at the same time.
