One of Sigmund Freud's early patients rushed out into an Austrian afternoon on her way to meet her best friend at a coffee house.
Over Cappuccino and Viennese pastries, she suddenly burst out crying.
Her friend begged her to share what was wrong.
"Oh, it's just terrible," she wailed. "Today the doctor told me I'm in love with my father, and. . .and. . .and you know, he's a married man!"
CatalysisIn 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.« |
