>> Hi, I'm Molly Wood. It's April 20, 2008 and here's what happened today in Technology History. In 1862, the first pasteurization test was completed by Louis Pasteur and Claude Bernard. Pasteurization is a process of heating liquids for the purpose of destroying viruses and harmful organisms, such as bacteria, protozoa, molds and yeast. This process differs from sterilization in that it does not intend to kill all microorganisms. Rather, it tries to achieve a logarithmic reduction in a number of viable organisms, thus reducing their ability to cause disease. On this date in 1964, BBC Two launched in the UK aimed at minority interests and more ambitious television programming. The launch itself was a bit of a fail as there was a massive electrical failure due to a fire at the Battersea Power Station, but things are going pretty well now. Finally on this date in 1972 Apollo 16 landed on the moon. It was the tenth manned mission in the Apollo program and the fifth mission to land on the moon. Now you know. I'll see you tomorrow.
