“The forces which displace continents are the same as those which produce great fold-mountain ranges. Continental drift, faults and compressions, earthquakes, volcanicity, transgression cycles and polar wandering are undoubtedly connected causally on a grand scale. Their common intensification in certain periods of the earth’s history shows this to be true. However, what is cause and what effect, only the future will unveil.”

– Alfred L. Wegener, German meteorologist and geophysicist (1880 – c. 1930)

“Measure what is measurable, and make measurable what is not so.”

– Galileo Galilei, Italian astronomer, physicist, and mathematician (1564–1642)
