The correct answer is true.
It is true that Sir Isaac Newton not only described the law of gravity, but he also discovered a mathematical relationship to measure the force of gravity between any two objects.
It is well known that Isaac Newton was a man ahead of his time. He had a brilliant mathematician mind and could compare the acceleration of the moon with the acceleration of things on our planet. He discovered the dependence of gravity upon the distance of different objects.
It all started with the fall of an apple from the tree and ended up as the Isaac Newton Law of Universal Gravitation.

Explanation:
Eratosthenes (276-194 BC) was a Greek mathematician and astronomer who made an amazingly close calculation of the actual circumference of the earth. He did it by noting the angle of shadows in two cities during the summer solstice, and then doing geometric calculations that factored in the distance between the cities.
Oh, and besides math and astronomy, Eratosthenes was also a poet and music theorist, as well as pretty much inventing the field of study we call geography today. He was what we would call a "polymath" (a person of knowledge of all sorts of things) -- or, what the Greeks called a <span>Πένταθλος (pentathlos).</span>
