Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Charles douard Guillaume (15 February 1861, Fleurier, Switzerland - 13 May 1938, S vres, France) was a Swiss physicist who received the Nobel Prize in Physics in 1920 in recognition of the service he had rendered to precision measurements in physics by his discovery of anomalies in nickel steel alloys. Guillaume is known for his discovery of nickel-steel alloys he named invar and elinvar. Invar has a near-zero coefficient of thermal expansion, making it useful in constructing precision instruments whose dimensions need to remain constant in spite of varying temperature. Elinvar has a near-zero thermal coefficient of the modulus of elasticity, making it useful in constructing instruments with springs that need to be unaffected by varying temperature, such as the marine chronometer.show more
