A worldwide survey was conducted by the UN. The only question asked was: "Would you please give your honest opinion about solutions to the food shortage in the rest of the world?" The survey was a huge failure. In Africa they didn't know what "food" meant. In Eastern Europe they didn't know what "honest" meant. In Western Europe they didn't know what "shortage" meant. In China they didn't know what "opinion" meant. In the Middle East they didn't know what "solution" meant. In South America they didn't know what "please" meant. And in the USA they didn't know what "the rest of the world" meant.

Johan August Brinell

Died 17 Nov 1925 at age 75 (born 21 Nov 1849).Swedish metallurgist who devised the Brinell hardness test, a rapid, nondestructive means of determining the hardness of metals. Brinell studied many aspects of iron and its production. Brinell´s important work on transformations in steel during heating and cooling. His discoveries about the control of the carbon containing phases is the present basis for the knowledge about properties of steel. The Brinell Hardness Test measures the relative hardness of metals and alloys, by forcing a 10mm hard steel ball into a test piece with a 3000kg load for 30 seconds and measuring the surface area of the resulting indentation. The load is reduced to 500kg for very soft materials and the steel ball is replaced with tungsten carbide for very hard materials.
