What do you plan to read this summer? What are you reading now?
I am currently reading "Degrees Kelvin" by David Lindley, published by Joseph Henry Press. The biography of Sir William Thomson, Lord Kelvin. He was a 19th century physicist probably best known for dicsovering the temperature at which atoms cease to move: -273.15 degrees Celsius (0 degrees Kelvin or absolute zero). He also performed a lot of the early groundwork for theories of electromagnetism and thermodynamics. Lord Kelvin devised a new compass for ships that would work well when surrounded by steel as the world's ship building began to move from wooden to iron vessels. A fascinating figure from history.
