            The Postcard

"Feb 19th. 1916.
Saturday.
From Maurice G. Cairns.

Ernst Mach

So what else happened on Saturday the 19th. February 1916?

Well, it was not a good day for Ernst Mach, because he died at the age of 78 on that day in Munich, German Empire.

Ernst Waldfried Josef Wenzel Mach, who was born on the 18th. February 1838, was a Moravian-born Austrian physicist and philosopher, who contributed to the physics of shock waves. 

The ratio of one's speed to that of sound is named the Mach number in his honour. As a philosopher of science, he was a major influence on logical positivism and American pragmatism. 

Through his criticism of Newton's theories of space and time, Ernst foreshadowed Einstein's theory of relativity.
