The First 'Pi Day' is Now Possible *
Actually the first 'pi day' will be March 14, 1592 (3.141592...) but you can't have the first pi day without accurately calculating pi out to at least 6 decimal places. But other than the novelty, why should we care? OK... if you are pouring concrete for a circular base for your water tank, or if you are using an auger to drill footings, you will need to know the number of square feet of concrete to have delivered to your job site but circles and cylinders are not square. The formula to make this calculation includes pi as a constant so having a good estimate of pi makes your final answer more accurate. For a small job it probably doesn't matter but as the jobs gets bigger, the errors increase. Many people in history can claim good estimates of pi using various methods. Even the Bible can make a kabbalistic mystical claim. Archimedes made the first generally accepted estimate. However, this year pi is finally presented as an irrational number that can be calculated accurately out to 6 decimal places so now we can have pi day. The man who accomplishes this is a French amateur mathematician, François Viète. His formula is unwieldy but its a first.      
Baby, It's Cold Outside... Hot Chocolate Comes to Europe
Hot chocolate wasn't invented in Switzerland. The word 'chocolate' comes from the Aztec name for the hot beverage they made out of the cocoa bean. Cocoa beans come from a tree that grows in the New World. The Aztecs believe it was brought down to them from the gods. Hence the scientific name for the cocoa tree translates into English as 'food of the gods'. After fermenting and drying, it is ground into a powder and made into a hot beverage which is thought to promote health. They also think it is an aphrodisiac. (Just wait until 'Lady Isabella' gets a swig of this stuff!) The Spaniards begin shipping the beans to Seville in production numbers this year. They will find the taste too bitter but mixing it with some honey or sugar makes it palatable.      
The Anglo-Spanish War and the Sum of Their Fears
The stuff has really hit the fan now. In general, the English have been supporting the Calvinists in small ways in the Netherlands as the Dutch continue their rebellion against Spanish rule. Queen Elizabeth the 1st of England has also authorized privateers to interdict Spanish shipments of gold and goods. Despite the King of Spain's previous marriage to Elizabeth's sister, Queen Mary, and Elizabeth's coy promises (your lips say, 'No, no,' but your eyes say, 'Yes, yes') the King has had enough. After the assassination of the leader of the Dutch rebellion, Queen Elizabeth has signed a treaty offering boots on the ground and enough money to constitute 1/4th of the budget of the rebellion. Sir Francis Drake sails to the New World and sacks Santo Domingo. England has joined the 80 Years' War.

His formula was: 2/pi = ((1/2)(((1/2 + 1/2 ((1/2))(((1/2 + 1/2((1/2 + 1/2(1/2))pi.... Unfortunately, this equation is not too useful in calculating ( because it requires too many iterations before convergence, and the square roots become quite complicated. He did not even use his own formula in his calculation of pi.”
- Pi - Wikipedia (2015). Retrieved on 29 May 2015. “Being an irrational number, π cannot be expressed exactly as a common fraction, although fractions such as 22/7 and other rational numbers are commonly used to approximate π. Consequently its decimal representation never ends and never settles into a permanent repeating pattern. The digits appear to be randomly distributed; however, to date, no proof of this has been discovered. Also, π is a transcendental number π a number that is not the root of any non-zero polynomial having rational coefficients. This transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straightedge.”

All historians have unanimously asserted that the Queen persistently starved her army and navy of money. One modern authority actually goes so far as to say that it is a misnomer to call the Anglo-Spanish war a war at all.
