Stephen Rannazzisi: Slow Pitch Softball

I joined a softball team, which I thought was a great idea... but the guys on my team are crazy. These guys show up to games -- slow pitch softball games -- with cleats, stirrups, the Barry Bonds arm guards on, the black crap under their eyes. Im like, Fellas, the ball is this big. If you cant see it, you probably shouldnt have driven to the game today.

Catalysis

In 1823, the effect of platinum as a catalyst was investigated by Johann Wolfgang Döbereiner, who found that hydrogen combined with air in the presence of platinum powder to form water, in a reacttion so vigorous that the filter paper holding the powder was charred. (It was later that the term catalysis was coined by Berzelius, in 1835.) Within a few days, on 3 Aug 1823, he invented the Döbereiner lighter process using the effect he had observed. He ignited a thin jet of hydrogen by passing it over spongy platinum in air. He designed a jar-type lighter using this method. Within three months, news of his discovery had been reported in some dozen European science journals. His lighter design was taken up by manufacturers to replace starting a fire with flint and tinder, and was in production for several decades.«
