A self-described “design scientist,” Buckminster Fuller is perhaps best known for his less-is-more approach to using modern-day technology to improve housing. That culminated in 1947 with the development of the geodesic dome, which uses lightweight materials to create large, enclosed spaces unobstructed by supporting columns. There are now more than 300,000 domes worldwide—just one relic of Fuller’s ingenuity.  A more recent addition to that list is Fuller’s Everything I Know, a 42-hour lecture series now available as a free download on the Internet Archive. Fuller recorded the 12 lectures in early 1975 and in them discusses the myriad concepts and applications he devised up to that point in his life—making for recordings that are as much his personal history as that of modern technological innovation.
