A little boy asked his teacher...

A little boy asked his teacher if he could go to the bathroom,so she said yes. When he went to wipe his bum there was no toilet paper so he used his hands. When he got back to class his teacher asked, 'What do you have in your hand.'The boy said, 'A little leprechaun and if I open my hand he'll get scared away.'
He was then sent to the principals office and the principal asked him, 'What do you have in your hand.'
So the little boy said, 'A little leprechaun and if I open my hands he'll get scared away.' He was sent home and his mom asked him 'What do you have in your hand.'
So the little boy said, 'A little leprechaun and if I open my hands he'll get scared away.' He was sent to his room and his dad came in and said, 'What do you have in your hand.' So again the little boy said, 'A little leprechaun and if I open my hands he get scared away.'
Then his Dad got really mad and yelled, 'Open your hands!'
And the little boy said, 'Look Dad you scared the crap out of him.'

Johan August Brinell

Born 21 Nov 1849; died 17 Nov 1925 at age 75.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.
