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.

Always know when to let go

Always know when to let go. When a thought is bringing you more misery than peace, let go of the thought; when a person is bringing more pain than joy to your life, let go… You cannot be your best if you lack joy and peace.
