Imagine finding the next rich oil deposit in the world. Marvin Mangus, with the help of a team, discovered the Prudhoe Bay Oil Field, the largest of its kind in North America. Mangus suspected the existence of a large oil field when he helped find the massive Kavik natural gas field in the area. He was able to convince ARCO to drill an exploratory well in Prudhoe Bay, which led to the discovery of oil. It also led to the creation of the Alaskan pipeline.
Glory comes into play when you are able to make the world a better place, or to at least help your fellow man understand it better. Who doesn't feel glorious when they make a discovery? (Probably the woman who discovers too late that her husband left the toilet seat up.)
