History tells us that the astute observations of Issac Newton, in relation to a particular apple he watched fall to the Earth long ago, ultimately let to the foundations of what became mankind’s understanding of gravity and the forces exerted by objects against one another in the universe. Since Newton first questioned what might have “pulled” fruit from the branches of trees, other similar questions have been pondered. For instance, do apples and oranges fall the same speed, or differently? Is the rate of speed at which they fall the only difference in how gravity might affect them? Even stranger, does the time of the year affect these differences (after all, Newton’s apple feel in August of 1666; what if he had witnessed it falling in the spring of that same year… not that the difference would likely have been perceptible)?
According to New Scientist Magazine, such questions might seem like peculiar concerns, but Indiana University’s Alan Kosteleckby
