This Chart Shows Who Marries CEOs, Doctors, Chefs and Janitors

When it comes to falling in love, it’s not just fate that brings people together—sometimes it’s their jobs. We scanned data from the U.S. Census Bureau’s 2014 American Community Survey—which covers 3.5 million households—to find out how people are pairing up. Some of the matches seemed practical (the most common marriage is between grade-school teachers), and others had us questioning Cupid’s aim (why do female dancers have a thing for male welders?). High-earning women (doctors, lawyers) tend to pair up with their economic equals, while middle- and lower-tier women often marry up. In other words, female CEOs tend to marry other CEOs; male CEOs are OK marrying their secretaries.

Johnny Depp est Donald Trump

Funny Or Die viennent de mettre en ligne un mockumentary de 50 minutes avec Johnny Depp dans le rôle de Donald Trump. Pour une fois qu'on prend plaisir à voir Johnny Depp grimé sous des tonnes de maquillage, ça se fête. On en oublierait presque que le milliardaire aux cheveux blonds pipi a remporté hier les primaires dans le New Hampshire. Notons, pour le plaisir, que ce moyen-métrage a été réalisé par Jeremy Konner, auteur de la géniale série Drunk History
Ci-dessous un trailer, et le film dans son intégralité ici .

From chrome plating to nanotubes: the 'modern' chemistry first used in ancient times

The ancient Babylonians were the first to use sophisticated geometry – a staggering 1,400 years before it was previously thought to have been developed. Sadly, these mathematical innovations were forgotten as the Babylonian civilisation collapsed and were only rediscovered this year as scientists took a close look at ancient clay tablets.

This surprising finding made me wonder about what other scientific methods that we put down to modern minds were actually discovered by ancient civilisations. So I decided to hunt down some of the most advanced uses of chemistry.

Qin Dynasty chrome plating

The mirrored shine of chrome-plated metal is almost a symbol of the modern era. A thin chrome layer coats metals and plastics in kitchens, bathrooms and cars. Credit for chrome-plating technology goes to George Sargent who published a method in 1920 that lead to the commercial plating that dominated the Art Deco period and beyond. In fact, other famous chemists including Robert Bunsen dabbled with chrome plating in the mid-19th century. But all of these may have been beaten to the shine by the metallurgists of the Qin dynasty in China some 2,000 years before chrome had even been identified in the West.

In the 1970s, razor sharp swords coated in a thin layer of chromium oxide were unearthed along with the the famous Terracotta army. The Chinese suggest that their 1st dynasty weapon smiths coated officers' weapons to protect them from corrosion. And indeed, two millennia later the blades are untarnished. However, whether this is really the case or in fact the chromium layer slowly formed from a peculiarity of the blade’s composition and the fires that ravaged the buried terracotta army is a matter of debate.

Roman concrete

Concrete is the mainstay of modern buildings, but ancient civilisations also used it to great effect. Concrete is a composite, meaning that it is made from two or more materials; cement is mixed with sand and gravel, which then sets into whatever structure is required. The most famous ancient concrete buildings are probably the Pantheon and Colosseum in Rome. Both are composed of fine volcanic ash mixed with lime (calcium hydroxide).

Together these make the cement, which sets and binds fist sized pieces of limestone together. This particular recipe produces a network of crystals that resist propagation of cracks, the bane of modern concrete. The result is an incredibly enduring material that is, in many ways, superior to today’s concrete. A testament to this is the majestic roof of the Pantheon, which, at 43 metres across, is still the world’s largest unreinforced concrete dome.

Damascene nanotubes

Carbon nanotubes are the strongest and stiffest materials known. They consist of cylinders with walls that are just one atom thick. When used within composite materials they can massively enhance the strength of an object resulting in super strong and light components, some of which you can find in wind turbines, sports gear and vehicles.

In 2006 researchers discovered that the people of Damascus were making use of nanotubes in their steel hundreds of years ago. The result was beautiful blades covered in swirling patterns. And more importantly for the soldiers of the time was the exceptional durability and the razor-sharp edges the steel held. We now know the exact composition of Damascus steel, yet modern metallurgists have failed to reproduce it so far.

Egyptian pigments

William Perkin is credited with producing the first organic dye (using chemists’ meaning of the word organic – in other words, carbon-containing chemicals) when he accidentally discovered purple mauveine while trying to make quinine in 1856.

But the first synthetic pigment of any type was probably made by the Egyptians as early as 3000BC. By heating a mixture of sand, ash, calcium carbonate (possibly from shells), and a copper containing ore to temperatures of over 800°C they manufactured blue calcium copper silicate. This could be then be used in glazes to produce a stunning range of hues.

Greek atomic theory

Democritus had it right all along.

The incredible technologies devised by craftsman and artists of ancient civilisations are astounding. Much of it can’t be bettered by modern techniques. But what separates science from skilled craft is an understanding of the underlying mechanisms involved in the making of the material. Underpinning this understanding in modern chemistry is the atomic theory often credited to John Dalton in the early 19th century. But philosophers of old also had a good crack at thinking about the nature of matter. And in fact atomism has sprung up multiple times in antiquity. Most notably from the Greek philosophers Democritus and Leucippus who speculated that everything is composed of physical, indivisible and invisible atoms back in the 5th century BC.
