Being the boss

A henpecked husband was advised by a psychiatrist to assert himself. "You don't have to let your wife bully you," he said. "Go home and show her you're the boss."

The husband decided to take the doctor's advice. He went home, slammed the door, saw his wife and growled, "From now on you're taking orders from me. I want my supper right now, and after you get it on the table, go upstairs and lay out my clothes. Tonight I am going out with the boys. You are going to stay at home where you belong. Another thing, you know who is going to tie my bow tie?"

"I certainly do," said his wife calmly, "the undertaker."

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.
