Waves and Beaches

Over 70% of the earth's surface is covered by water. The beaches, the boundary between the oceans and the other 30% of the surface where we live, is constantly battered by waves. This week I had a conversation with Kim McCoy, author of the third edition of Waves and Beaches. Kim has recently completed an Ironman and will continue to swim, dive, surf, sail, rock-climb and paraglide until motion stops, viscous drag ceases, buoyancy is lost, and gravity ultimately wins.
