For example, oxygen ions move to a zinc or iron plate, become chemically attached and deliver charge. By carefully measuring currents

diseases were beriberi (a word derived from the language of Polynesian natives meaning “I can’t move, I can’t move”) and scurvy, an illness well known to seamen. It took researchers until 1912 to uncover the [...] that the white rice contained the germ that caused beriberi and that the red coating, which was re- moved by polishing the rice, provided an antitoxin. This point is crucial to understanding why successful
