The Gospel Wealth is <span>An essay written by Andrew Carnegie in 1889 that described the responsibility of philanthropy by the new upper class of self-made rich. The central thesis of Carnegie's essay was the peril of allowing large sums of money to be passed into the hands of persons or organizations ill-equipped mentally or emotionally to cope with them. As a result, the wealthy entrepreneur must assume the responsibility of distributing his fortune in a way that it will be put to good use, and not wasted on frivolous expenditure.

Plate tectonics is a scientific theory that describes the movement of plates of the Earth’s lithosphere. The model builds on the concept of continental drift, which proposed that continents had “drifted” relative to each other across the ocean bed. The speculation was first put forward by Abraham Ortelius in 1596. The concept was developed independently by Alfred Wegener in 1912, but the theory was generally rejected.
It was only with the discovery of mid-oceanic ridges in 1947 that the theory began acquiring evidence. Scientists also used devices developed during WWII to study odd magnetic variations across the ocean floor. By 1967, plate tectonics were fully accepted in modern geophysics.
