    This animation from Moonwalk One shows all the stages of the Apollo 11 mission, which launched 45 years ago on July 16, 1969.  As designed, the only component to return to Earth was the Command Module Columbia.

    Moonwalk One, ca. 1970

    The Brachistochrone
    This animation is about one of the most significant problems in the history of mathematics: The Brachistochrone Challenge:

    If a ball is to roll down a ramp which connects two points, what must be the shape of the ramp’s curve be, such that the descent time is a minimum?

    Intuition says that it should be a straight line. That would minimize the distance, but the minimum time happens when the ramp curve is the one shown: a cycloid.

    Johann Bernoulli posed the problem to the mathematicians of Europe in 1696, and ultimately, several found the solution. However, a new branch of mathematics,Calculus of Variations, had to be invented to deal with such problems. Today, calculus of variations is vital in Quantum Mechanics and other fields.
