Provided work to help prove Christian Doppler's sound and light wave propagation concepts. Mach devised a simple experiment that was able to prove that the Doppler effect was real, at least for sound. He developed techniques to measure sound waves and created a scale for measurements. He named it after himself. The Mach number. It was the ratio of speed of sound to the speed of the object. It's not absolute and is relative. Doppler Effect

Studies physics, mathematics, and philosophy
-
Although his primary studies were in physics he was very interested and studied philosophy and human physiology.

Published this as his interpretation of the conservation of energy. Claiming that it's not a product of mechanical physics and provides his definition of mass. First published in German, 1872. Translated to english 1911. Ernst, Mach. "The History and Root of the Principles of the Conservation of Energy" 1872

This is his primary study. His comprehensive work on the foundations of mechanics. Mach shows that the laws of mechanics are not absolute but are relative to the observer. He counters Newton's Laws. He also shows that inertia is not a property of matter but is a result of the interaction of bodies with the rest of the universe. Mach's Principle Mach, Ernst. "The Science of Mechanics". 1883

Develops his philosophy of science. That all knowledge is based on sensory experience and that the mind is a result of environment on the senses and perception.

Einstein's work is heavily influenced by Mach's ideas on motion, mechanics, and constancy of speed of light. The Mach principle was paramount in the development of his theory of general relativity.

Moves closer to his son Ludwig Mach, a long time contributor who helped him with many of his experiments over his career.
