Physics of haiku, blizzards, and Thor’s hammer

By Hamish Johnston

Students at Camden School for Girls in London have published a lovely book of haiku about science. Called Sciku: The Wonder of Science – in Haiku!, the volume contains 400 poems and is on sale with proceeds going to upgrading the science labs at the school. The students are not the only ones at the school with literary ambitions. Their science teacher Simon Flynn has also written a book called The Science Magpie, which we reviewed two years ago.

Below is a little taste of what is inside the book of haiku and you can also watch several of the students read their poems in the above video.

Gravity:
An attractive force
Between all objects with mass
Just like you and me

A visit to an island called Nuuk

The story of Nuuk began in the early 18th century when a French naval officer landed on a barren, ice-covered island and noted its coordinates in his logbook. The island, he reported, was volcanic in nature, but little else was known about it; indeed, later visitors to its supposed location found no sign of land. Rediscovered in the 20th century, Nuuk was soon visited by a series of scientific expeditions, one of which noted that the island’s surface area was shrinking. An observation station was set up on a prominent headland, but in 2012, it abruptly ceased transmitting; satellite images later revealed that Nuuk had vanished entirely beneath the ocean surface. Coincidentally, the final signal from Nuuk arrived just as the 34th International Geological Congress was meeting in Australia to discuss the emergence of a new, human-influenced geological age: the Anthropocene.

Nuuk and the various forces that contributed to its demise are the subject of a fascinating exhibition currently on show (until 29 November) at the GV Art gallery in London. Lost in Fathoms is a collaboration between an artist, Anaïs Tondeur, and a physicist, Jean-Marc Chomaz, who specializes in fluid dynamics. To develop her ideas about Nuuk, Tondeur spent a year in residence at Chomaz’s Laboratoire d’Hydrodynamique at the Ecole Polytechnique in France, while other parts of the exhibition grew out of a summer school in Cambridge, UK, that focused on fluid dynamics, sustainability and the environment.

A huge cycle in Sheffield, $30,000 for falsifying global warming and another physicist goes into advertising

Sports fans in the UK are spoiled for choice this weekend, with the Wimbledon finals in London and the kick-off of the Tour de France in Leeds. This is only the second time that the famous bicycle race has started in the UK and to celebrate, the University of Sheffield has created a huge image of a bicycle in a field near to the route. But as well as celebrating the passing cyclists, the image honours a very different cycle that makes the race and indeed much of life on Earth possible.

A new Longitude Prize, global cooling in the 1970s, inspirational creatures and more

A bird of prey swoops out of the sky, grabs its victim from the ground and flies off into the distance. It’s what a bird does instinctively, but how could we get a drone aircraft to do the same thing? That’s the subject of one of the papers in a special issue of the journal Bioinspiration & Biomimetics that focuses on “Bioinspired flight control”.

The above sequence of images is from a paper entitled “Toward autonomous avian-inspired grasping for micro aerial vehicles” by Vijay Kumar and colleagues at the University of Pennsylvania. The special issue also includes work on aircraft inspired by flying snakes, flocking birds and incredibly stable moths.
