Here are some one liners...
Franklin Stove 1.0 -- Benjamin Franklin does not patent his famous stove which allows for people to improve on his idea. I talk about copyrights and patents and why they should be short.
Cotopaxi Is Rumbling. What Could go Wrong? -- I talk about an existing problem with this volcano and how 300,000 are engaged in normalcy bias.
The Adams Family Roundup -- Abigail Adams is born. I talk a little bit about the love affair between her and John Adams and her help in forming the USA.
Major Events -- Gerrymandering, Wahhabism and the founder of British India arrives on the scene.
Franklin Stove 1.0Benjamin Franklin has been trying to increase the heat efficiency of the colonial fireplace. In fireplaces, most of the heat goes up the chimney with the exhaust gases rather than radiating into the room so Franklin funnels the gases past an iron plate that presumably radiates its heat back into the room. Then he tries a freestanding stove, but it smokes too much so he contracts with Robert Grace to build a new design. This is the familiar Franklin Stove but Franklin calls it a Pennsylvania Fireplace. The price is 5 pounds sterling or about $1,000 in 2014 dollars. It funnels exhaust fumes past a baffle to absorb the heat. The baffle is connected to a duct of cold-air that is drawn upward by the convection current of warm air in the baffle and radiates out the back as heated air. The Governor of Pennsylvania suggests that Franklin patent his design, but he refuses saying, "...as we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours, and this we should do freely and generously." Unfortunately the 1.0 design is not a great success due to its complexity and the cold air only draws when the stove is really hot. Nevertheless, later improvements will be made to the Franklin Stove over the years and these will help its popularity considerably.   
Cotopaxi Is Rumbling. What Could go Wrong?This is not the first time the volcano Cotopaxi, in present day Ecuador, has blown its top. The last time was two years ago. Nevertheless, the volcano eruption has flattened the town of Latacunga which is about 21 miles away. The volcano will do so again in 1789. Then almost a century later (in 1877) the town will be buried in a mudslide as the snow cap melts from volcanic steam and carries away the earth and ash. This is a very active volcano and will remain so into the modern day.  
The Adams Family RoundupAbigail (Smith) Adams is born this year in Weymouth, Massachusetts. Her father is a congregational minister whose preaching focuses on reason and morality. She will eventually fall in love with and marry John Adams, the first Vice President of the United States and the second President of the United States. That will make Abigail, the first "Second Lady" and the second "First Lady". (Say that three times fast.) She will also be mother to John Quincy Adams, the 6th President of the United States. She will be related to just about everyone including her own husband who is already hanging around. He is currently 9-years-old and her 3rd cousin. She will be home-schooled by her mother, and will become one of the most well-read First Ladies of the United States and the first to reside at the White House which will be only partially completed by that time. She will also involve herself so much in politics that people will call her "Mrs. President."
