Newton's theory of gravity
Discussed in relation to experiments and measurements, particularly Newton's law of universal gravitation and his inability to measure the gravitational constant 'G' separately from other masses. It's also presented as a predecessor to Einstein's theory, containing problems that Einstein's theory solved.
