Zeno's Paradox is an early (ancient Greece) confrontation with infinity and infinitesimal. It took around 2,000 years to resolve the paradox, using the methods of modern (post 1850) calculus. This video shows the paradox; a later one will explain it with calculus ideas. Infinity and infinitesimal are difficult concepts to apply to mathematics, producing a number of surprising results and observations. This video is part 1 of a series dedicated to discussing some of these ideas in layman's terms. I spelled his name Xeno in the video, but apparently Zeno is the more common spelling.
