Ch. 2: Review Questions: The Scientific Method

The following questions relate to the following story:

The discover of Neptune is another excellent example of the scientific method in use.

Scientists had noticed that the planet Uranus did not orbit around the sun exactly as Newton's Law of Universal Gravitation predicted.

French scientist Urbain Jean Joseph Leverrier assumed this was because a previously undiscovered planet was interfering with Uranus's movement. He made some calculations using Newton's Law of Universal Gravitation and determined where this undiscovered planet had to be in order for Uranus's motion to be consistent with Newton's Law.

German scientist Johann Gottfried Galle used a telescope to look in the sky at the position Leverrier had predicted, and he saw the planet on the very first night of the search.

The planet was named Neptune.
