Weber was a German physician who is considered one of the founders of experimental psychology. “In 1821, assisted by his brother Wilhelm,—then only seventeen years old and preparing for his university entrance examination—Weber began a long physical study of the flow and the progress of waves in fluids, particularly in elastic tubes. In their Wellenlehre (1825) they formulated the basic laws of hydrodynamics and were the first to apply that branch of physics to the circulation of the blood. Ernst studied—at first with Wilhelm, a precocious genius—the mechanical properties of the arteries, describing them as they would a technical device, the effect of elasticity transforming the pulsatile movement of the blood in the large arteries in to a continuous flow into the small ones (1827). He also showed that the pulse is a wave in the arteries caused by the heart action and that its propagation—calculated from the delay of pulsation in a more distant artery—is much faster than the flow of the blood (1834) and that besides dilatation due to the pressure inside an elastic tube, blood vessels also change their diameter under the influence of nerves on the muscle wall (1831). He summarized his findings, the theory of waves in elastic tubes, and they laws of the movement of blood in the vessels in 1850.” . 2
