Dan DeBra) once said, roughly, âall instruments are first and foremost thermometers, but sometimes they measure something else as wellâ. He was talking about temperature compensating strain gauges, but he was also in charge of an ultra-precision machining laboratory â the one that built the gyros for Gravity Probe B.
In mathematics, a quotient is the result of division. For example, when dividing 6 by 3, the quotient is 2, while 6 is called the dividend, and 3 the divisor. The quotient further is expressed as the number of times the divisor divides into the dividend, e.g. 3 divides 2 times into 6. A quotient can also mean just the integer part of the result of dividing two integers. For example, the quotient of 13 and 5 would be 2 while the remainder would be 3.
Reaction quotient. In chemistry, a reaction quotient (Qr) is a function of the activities or concentrations of the chemical species involved in a chemical reaction. In the special case that the reaction is at equilibrium the reaction quotient is constant and equal to the equilibrium constant that appears in the expression of the law of mass action. A general chemical reaction in which Î± moles of a reactant A and Î² moles of a reactant B react to give Ï moles of a product R and Ï moles of a product S can be written as
