Here are some one liners...
Global Cooling, Monster Storms and the Coming Maunder Minimum - I note the flooding, the Plague and the death of King James. I then complain about Global Warning panic.
What a Relief! Glauber's Salt is Discovered -- This chemical is a laxative but it is interesting because it is also used in solar energy applications.
The Slide Rule and the Old School Mystique -- Yes. The Slip Stick is invented. I talk about how I got a job because I knew how to use one.
Global Cooling, Monster Storms and the Coming Maunder MinimumWe are currently midway through the Little Ice Age, and unusually strong storms are the rule now. The Pilgrims have logged a 20 foot tide at New Plymouth due to a major storm. Back in England, the Thames has risen to such a height that the sea wall at Kent has collapsed. Essex and Lincolnshire are inundated. Take note. This is not the normal flooding that might torment the average yeoman or minor nobleman. This is record-breaking flooding. This bad weather is a terrible omen for the future. Speaking of bad omens, King James the 1st has died and his son, Charles the 1st has taken the throne of Great Britain, but it's not as if England has been hit by Plague too. Oh... wait. Over 68,000 die of Plague this year... most in London itself. The bad times are not over yet.       
What a Relief! Glauber's Salt is DiscoveredThe official chemist of the Holy Roman Emperor, Johann Glauber, discovers hydrated sodium sulfate. It's main use at this time is as a laxative called Miracle Salt. Later it will be known as Glauber's Salt and it's uses will be wide ranging, included in the processing of paper, glass and use in some laundry detergents. It can also be used for solar energy applications since it changes from solid to liquid at 90 degrees Fahrenheit.     
The Slide Rule and the Old School MystiqueIn the last few years logarithms have been introduced, but now a practical use for logarithms allows one to multiple and divide using two scaled rulers slipping past each other. This device is called the slide rule. It is invented by William Oughtred who is the same guy who invented the x used for multiplication. Example: 5 x 5 = 25.
