Sam Browne belt Sam Browne belt The Sam Browne belt is a wide belt, usually leather, supported by a narrower strap passing diagonally over the right shoulder (although Royal Canadian Mounted Police non-commissioned members wear theirs over the left shoulder). It is most often a part of a military or police uniform. General Sir Sam Browne was a 19th-century British Indian Army officer who had lost his left arm; this made it difficult for him to draw his sword, because the left hand was typically used to steady the scabbard while the right drew out the sword. Browne came up with the idea
19th century in science for solids and discovery of Navier–Stokes equations for fluids. In the 19th century, the connection between heat and mechanical energy was established quantitatively by Julius Robert von Mayer and James Prescott Joule, who measured the mechanical equivalent of heat in the 1840s. In 1849, Joule published results from his series of experiments (including the paddlewheel experiment) which show that heat is a form of energy, a fact that was accepted in the 1850s. The relation between heat and energy was important for the development of steam engines, and in 1824 the experimental and theoretical work of Sadi Carnot was published.
