Patton Oswalt: The Apocalypse

Were probably going to die in the f**king apocalypse, but you know whats kind of exciting about that is that if the apocalypse actually goes down -- and I mean the f**king biblical apocalypse -- and if that starts to happen -- I mean, like, the ground opening up and demons flying out and gnawing on your flesh -- it means a couple of things. One: It means that Im wrong, and there is God and there is an afterlife. Two: It means that since there is an afterlife, you will be in the f**king VIP section of the afterlife.

First U.S. Bessemer steel rails

In 1865, the first Bessemer steel rails ever rolled in the U.S. were a few rolled at the North Chicago Rolling Mill from hammered blooms made at the Wyandotte rolling mill from ingots of steel made at the experimental steel works at Wyandotte, Mich. The American Iron and Steel Association was in session in Chicago at that time, and several of its members witnessed the rolling of these rails. The North Chicago Rolling Mill was the first large iron and steel plant in the Chicago area, founded in 1857. The first steel rails rolled for a business order in the U.S., were made at the Cambria Iron Company, at Johnstown, Pa., in Aug 1867, from ingots manufactured at the works of the Pennsylvania Steel Company, at Harrisburg, Pa.*[Image: detail from engraving of the much larger area covered by the factory buildings.]
