Seven packed days of events, from the science of tall sailing ships to Orkney's latest developments in tidal power and hydrogen for transport. There are plans to row the North West Passage through the Canadian Arctic, and the story of the cave bear and other European Ice Age animals. There are bees through the microscope, black hole discoveries, new ideas for the origin of life, and the story of a possible extraterrestrial contact. We'll look at the uninhabited island of Swona, with its distinctive feral cattle, plants and seals; hear about a Shetland weaver who developed his own inoculation system against smallpox two centuries ago; and learn about the Caithness man who invented the electric clock and fax machine. We'll also take a musical journey along the old northern sea-routes of saga times. All the presentations are online and free. Wildlife walks are also available to book.
