WebShips have six degrees of freedom in ship motion as shown in figure 1 [SNAME (1950)]. Maritime lectures in a conventional classroom can only explain ship’s motions one by one, but those motions ... WebEinstein and Relativity. The ideas outlined in Newton’s laws of motion and universal gravitation stood unchallenged for nearly 220 years until Albert Einstein presented his theory of special relativity in 1905. Newton’s theory depended on the assumption that mass, time, and distance are constant regardless of where you measure them.
