Bird Flight

Exactly how birds acquired the ability to fly has baffled scientists for years. Archaeopteryx provided a starting point for speculation. Built like a dinosaur, but with wings, scientists guessed at how a hypothetical ancestor might have taken flight. Some scientists support the arboreal hypothesis (e.g., Feduccia 1996) and suggest that the ancestors of Archaeopteryx lived in trees and glided into flapping flight (Figure to the right). But others argue that the claws of Archaeopteryx weren't suited to climbing. So, others support the cursorial hypothesis (e.g., Burgers and Chiappe 1999) and suggest that these ancestors used their long, powerful legs to run fast with their arms outstretched, and were at some point lifted up by air currents and carried into flapping flight.

Clipper Round The World Race

The Clipper Race is one of the biggest challenges of the natural world and an endurance test like no other. With no previous sailing experience necessary, it’s a record breaking 40,000 nautical mile race around the world on a 70-foot ocean racing yacht. The brainchild of Sir Robin Knox-Johnston, the first person to sail solo non-stop around the world, the event is now in its twelfth edition, the Clipper 2019-20 Race. Started from London on 1 September 2019, the fleet will complete its circumnavigation when it returns eleven months later, in August 2020. Divided into eight legs and between 13 and 16 individual races, you can choose to complete the full circumnavigation or select individual legs. It is the only race in the world where the organisers supply a fleet of eleven identical racing yachts, each with a fully qualified skipper and first mate to safely guide the crew. Normally the domain of seasoned pros, this supreme challenge is taken on by ordinary, everyday people. Having completed a rigorous training course, participants are suited and booted in the latest extreme protection gear to commence the race of their lives - an unparalleled challenge where taxi drivers rub shoulders with chief executives, vicars mix with housewives, students work alongside bankers, and engineers team up with rugby players. The sea does not distinguish between Olympians or novices. There is nowhere to hide - if Mother Nature throws down the gauntlet, you must be ready to face the same challenges as the pro racer. Navigate the Doldrums en route to South America, endure epic Southern Ocean storms, experience South African sunsets, face the mountainous seas of the North Pacific - and bond with an international crew creating lifelong memories before returning victorious.

BigDog is the alpha male of the Boston Dynamics robots. It is a rough-terrain robot that walks, runs, climbs and carries heavy loads. BigDog is powered by an engine that drives a hydraulic actuation system. BigDog has four legs that are articulated like an animal’s, with compliant elements to absorb shock and recycle energy from one step to the next. BigDog is the size of a large dog or small mule; about 3 feet long, 2.5 feet tall and weighs 240 lbs.

The study of artificial arms and hands began in 1967 incorporating the technological assets gained from developing the active prostheses started three years before. The studies had at first aimed only to develop machines to perform manual labor in lieu of persons and emphasized development of artificial hand mechanisms. Recently the aim has been to develop robots which can perform intelligent work as well as manual labor.
