DAGUERRE PHOTOGRAPHIC SYSTEM
January 7, 1839 - Académie des Sciences, Paris
Louis Daguerre made the first announcement of his photographic system at the Académie des Sciences in Paris, though details were not presented until 19 Aug 1839 when the process was announced publicly. By that time, the French government had bought the rights to the process from him, and then made them freely available to the world. However, this process had also been patented in England and Wales on 14 Aug 1839 - only five days previously.
THERMAL CRACKING PATENT
January 7, 1913 - U.S. patent (No.1,049,667)
A U.S. patent for the thermal cracking of crude oil was issued to William Merriam Burton (No.1,049,667). A crude petroleum mixture of various hydrocarbons can be separated into several groups of constituents by physical means, commonly distillation. His thermal cracking process used high heat and high pressure to chemically break longer molecules of less volatile components into smaller molecules, more than doubling the yield of gasoline which was much needed to fuel the motor industry. In its first 15 years of use the process saved more than 1 billion barrels of crude oil. In 1937 the invention of catalytic cracking superseded the Burton process, but it remains in wide use.

about Stolen On New Year's
More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)

about Eyesight Myth and Fact
Myth: Staring at a computer screen all day is harmful to the eyes.
Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them. Make sure lighting doesn't create a glare on your screen. When spending long periods at your keyboard, take a break now and then to rest your eyes to reduce fatigue. Also, don't forget to blink. Your eyes need to stay lubricated to feel comfortable.
