Leatherback Trust also recently embarked on an environmental education program at the local and national level. Two of the most successful public outreach programs cosponsored by The Leatherback Trust were The Great Sea Turtle Race and Cheer For The Turtles. The Great Sea Turtle Race used data from satellite tracked leatherback turtles leaving their nesting beaches at Playa Grande and heading to their feeding areas south of the Galapagos Islands. Using the tracking date a hypothetical race was staged between the turtles, with the winner being the turtle who reached the Galapagos Islands first. The race, co-sponsored by Conservation International, occurred on
History of manifolds and varieties spaces with a differentiable or topological structure, while "variety" refers to spaces with an algebraic structure, as in algebraic varieties. In Romance languages, manifold is translated as "variety" – such spaces with a differentiable structure are literally translated as "analytic varieties", while spaces with an algebraic structure are called "algebraic varieties". Thus for example, the french word "" means topological manifold. In the same vein, the Japanese word "" (tayōtai) also encompasses both manifold and variety. ("" (tayō) means various.) Ancestral to the modern concept of a manifold were several important results of 18th and 19th century mathematics. The oldest
