    In 1546, Niccolo Tartaglia became the first person to discover that a projectile should be fired at 45° to maximize range. His conclusion was based on incorrect theory as can be seen in his diagrams.pic.twitter.com/SoYlNXI7Yc

        Years later this idea was improved by Willya Schuttenau (1721-1783) in Düsseldorf who fixed a small cannon to the minute hand of a church clock. The gun fired at 7.5 minutes after every hour. Neighbors nearby sold their homes at a loss.

        Theory was incorrect but conclusion was perfect. In the end for people only result matters,all efforts are just ignored as if conclusion or end result was direct and a magic.

        In between two maximums - 0 and 90, someone could've easily guessed it to be 45

        Very much like between 0°C and 100°C, the 50°C is the ideal temperature for a human.

        Did this theory assumed zero air resistance, because it isn't true in practice! https://en.wikipedia.org/wiki/Range_of_a_projectile …pic.twitter.com/xXUiA5phTl

        Maybe a more striking historical example is Ptolemy's calculation of planetary orbits which gave more accurate results with the Earth at the center than Copernicus's until Kepler brought elliptical orbits into consideration.

        I can't read the language but the diagram appears to indicate an initial period of travel in a straight line without the immediate effects of gravity.
