The OpenScience project is dedicated to writing and releasing free and Open Source scientific software. We are a group of scientists, mathematicians and engineers who want to encourage a collaborative environment in which science can be pursued by anyone who is inspired to discover something new about the natural world. Much of the work of science depends on having appropriate tools available to analyze experimental data and to interract with theoretical models. Powerful computers are now cheap enough so that significant processing power is within reach of many people.
