Teflon was discovered accidentally

Teflon is the trade name for polytetrefluoroethylene, which was discovered in 1938 by American chemist Roy J. Plunkett. He discovered the material accidentally while working to develop a non-toxic refrigerant from gaseous tetrafluoroethylene. Instead, he came up with a waxy white powder which indicated that the molecules polymerized or combined with each other.

Plunkett went on to develop a method for producing the powder commercially. Teflon was first used for producing gaskets and valves needed in the development of the atomic bomb. The first Teflon-coated muffin tins and frying pans were sold in 1960. Teflon is now used for artificial cornea, substitute bones for chin, nose, hip, and knee joints and other anatomical plants.

Love-True and Great

If you develop love truly and great, rid of the desire to hold and possess, that strong clean love untarnished by lust, that love which does not expect to be repayed, that love which is firm bout not grasping, enduring but not tied down, gentle and settled, diamond-hard, but not interfering, giving more than taking, dignified but not proud, soft but not weak, that love which leads to enlightenment, them you will be washed of all ill-will.
