Eric Laithwaite 1974 Christmas Lecture 2: Tweedledum and Tweedledee

In this video I have uploaded Eric Laithwaite's 1974 lecture titled Tweedledum and Tweedledee. This is the second of his series of Christmas Lectures at the Royal Institution. This second lecture explores symmetry in engineering, electromagnetism, and everyday life. He also explores the idea of right vs left handedness in many ordinary objects which we may not have suspected to be there. Eric also shows some very interesting and unique demonstrations with magnets.
