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 History of manifolds and varieties The study of manifolds combines many important areas of mathematics: it generalizes concepts such as curves and surfaces as well as ideas from linear algebra and topology. Certain special classes of manifolds also have additional algebraic structure; they may behave like groups, for instance. In that case, they are called Lie Groups. Alternatively, they may be described by polynomial equations, in which case they are called algebraic varieties, and if they additionally carry a group structure, they are called algebraic groups. The term "manifold" comes from German "Mannigfaltigkeit," by Riemann. In English, "manifold" refers to
