About Time: A First Look at Time and Clocks

(4) K-3 Koscielniak focuses his impressive history of timekeeping on clock technologies developed over centuries. He starts with the employment of natural events; moves to the design of sundials, water clocks, and mechanical clocks; and ends with today's use of crystals and atoms to keep time in increasingly smaller increments. The loose watercolors have an amateurish quality except when portraying the detailed schematics of various clocks.
