Now that you understand something about electrostatics and static electricity, it is easy to understand the purpose of the Van de Graaff generator. A Van de Graaff generator is a device designed to create static electricity and make it available for experimentation. The American physicist Robert Jemison Van de Graaff invented the Van de Graaff generator in 1931. The device that bears his name has the ability to produce extremely high voltages -- as high as 20 million volts. Van de Graaff invented the generator to supply the high energy needed for early particle accelerators.
If a player pitches 46 - 60 pitches in a day, two (2) calendar days of rest must be observed. If a player pitches 31 -45 pitches in a day, one (1) calendar day of rest must be observed. If a player pitches 1-30 pitches in a day, no (0) calendar day of rest is required.f a player pitches 46 - 60 pitches in a day, two (2) calendar days of rest must be observed.

The last pitcher to throw as many as 15 complete games in a single season was Curt Schilling, who accomplished that feat for the Philadelphia Phillies in 1998. The last pitcher to throw 20 complete games in a single season was Fernando Valenzuela, who did so for the Los Angeles Dodgers in 1986. The last pitcher to throw 25 complete games in a season was Rick Langford, who had 28 for the Oakland Athletics in 1980. The last pitcher to throw 30 complete games in a season was Catfish Hunter, who did so for the New York Yankees in 1975.
