Stainless steel, which was developed in England in 1913, has a high tensile strength and resists abrasion, corrosion, and rust because of its high chromium content. Over 150 grades of this iron-carbon alloy now exist, and it is widely used to make cookware, cutlery, hardware, surgical instruments, watches, appliances, building materials, and industrial equipment. It is also used as a structural alloy in automotive and aerospace assembly. What is the passivation layer?

German physicist Wilhelm Wien was awarded the Nobel Prize for Physics in 1911 for his work on heat radiation. In 1893, he used theories about heat and electromagnetism to compose Wien's Displacement Law, which relates the maximum emission of a blackbody to its temperature. Max von Laue, a physicist who won the Nobel Prize for Physics three years after Wien, once credited Wien with â€œarray(leading); us to the very gates of quantum physics.â€ A crater on what planet is named in his honor?
