Who invented longitude and latitude?

Hipparchus was a sharp critic of Eratosthenes' geography and improved upon his grid system, using trigonometry to plot exact locations upon the grid. Both Greek cartographers were indebted to the ancient Phoenicians, for they were the first to determine latitude, or distance from the Earth's poles. The Phoenician method was based on astronomical observations. Longitude cannot be determined via such observations, so the problem of accurately determining longitude from any location on Earth continued right up until 1762, when English inventor John Harrison developed a method for determ..

What did Albert Einstein contribute to mathematics?

It was Einstein's theory of relativity that gave the world the equation E = mc2. This equation was used with dangerous consequences as one of the key components to the building of the bomb in President Franklin D. Roosevelt's Manhattan Project. This atomic bomb would later be used against Japan to help end World War II. Einstein, however, was not involved in this process as government officials believed that he was a security risk and might compromise the operation.Einstein's theory of relativity proposed a radical idea that space must be curved around huge objects if it was to ..

What are some Charles Darwin inventions?

As a young naturalist and geologist, Darwin spent almost five years on a round-the-world voyage aboard a ship called the "Beagle." During that voyage, Darwin collected specimens and made observations that led him to conclude that all species descended from common ancestors and that the gradual change in biological populations resulted from a process he called "natural selection." This process explains the struggle for existence as survival traits are passed down. As a result, new species emerged.
