Contributions to the 'Doppler theory' Ernest Mach, Born, February 18, 1838 – February 19, 1916
Mach created a simple device demonstrating that the Doppler effect was real. He created a tube with a whistle at one end mounted to rotate in a vertical plane. When the listener stood in the plane of the rotation axis, no pitch changes could be heard. But if the observer stood in the plane of rotation, variations in pitch that corresponded to the rotation speed could be heard.

"The Science of Mechanics: A Critical and Historical Account of Its Development"Ernest Mach, Born, February 18, 1838 – February 19, 1916
Mach studied the mechanic's process, offering an analysis combining history and philosophy. He examines the evolution of the theories, shedding light on principles and notions. This ensured his work remained a resource for physical mechanics.

Principle in cosmology, Ernest Mach, Born, February 18, 1838 – February 19, 1916
One of his most significant contributions came in 1897 with Mach's principle in cosmology, which theorized the concept of inertia originating from the interaction between the mass of objects within the universe.Banerjee, S.
