Here are some one liners...
The House of Saud and the House of Wahhab -- The guy who will set up the ruling dynasty of Saudi Arabia takes control of the family this year. I also talk about the problem with fundamentalism.
Voltaire Is Given the Boot -- The French playwright and philosopher is exiled to England. I talk about deism, and science.
The Invention of the Gridiron Pendulum -- It is a clever design made by the fellow who will bring about accurate navigation at sea.
The House of Saud and the House of WahhabShaikh Saud has passed away and his son, Muhammad, has taken over the leadership of the House of Saud, turning it into a dynasty. He will expand its territories near modern day Riyadh into a small emirate. (An emirate is a territory or state and Muhammad will become its Emir.) During the mid-1700s the Emir will make a deal with the House of Wahhab, often called Wahhabists. They prefer to be called Salafists (meaning, the Pious Ones). There is a certain appeal to a religious movement with clear-cut rules. There is also a potential conflict with a ruling government since fundamentalists do not draw a clear line between the secular and the sacred. The House of Saud will agree to protect the House of Wahhab. In exchange the House of Wahhab will not take over the Emirate. It will be a difficult balance to maintain over the centuries. The Emir will rule until his death in 1765. He will be succeeded by his son, Abdul Aziz, who will expand the emirate into about two-thirds the size of modern day Saudi Arabia.     
Voltaire Is Given the BootLast year the playwright, Voltaire, was arrested for challenging a man to a duel. The Queen of France loved his plays and gave him money for his efforts, but some fellows didn't particularly like his haughty attitude so one evening a few ruffians gave Voltaire a beating. He knew who had ordered it since the man was shouting from his carriage "Don't strike his head; something good may come out of that." After some practice with his sword Voltaire challenged the man to a duel, but dueling is a capital offense in France, and the King was unwilling to have Voltaire killed so he had him put into the Bastille for his own good. Voltaire pleaded for his freedom willing to accept exile to England, and so it was granted. This year he lands on the shores of Greenwich in the midst of a festival. He is delighted and he will learn a lot about the freedoms granted Englishmen and the chains that still bind them. He will also find himself penniless. The line of credit he had arranged with a banker in London was no good. The banker had gone bankrupt, but Voltaire soon found many people willing to back him for the next three years. He will learn a lot that he can carry back to France, and it is going to rock the world.  
The Invention of the Gridiron PendulumThe fellow who will invent the marine chronometer will first have to solve certain accuracy problems with clocks. The current problem is the length of a pendulum. A pendulum is made from a metal rod and the rod has a certain length to ensure that it swings back and forth at a known and calculated speed. Unfortunately differences in temperature throughout the day and from season-to-season will cause the metal rod to expand and contract, thus lengthening and shortening the rod. Enough inaccuracies creep in that it has become a problem. John Harrison solves this problem with a clever combination of different metals arranged in a frame. The different metals expand and contract at different rates and offset each other, thus keeping the length of the pendulum constant.
