and for the sake of redundancy's sake...
Here are some one liners...
The Origin of the Bayonet -- I talk about how fire rate determines when a bayonet charge will be successful and how the British used muskets during the American Revolution instead of the new Ferguson rifles. Big mistake.
OMG! No Smoking in Church! #IsNothingSacred? -- I talk about how the Pope prohibits smoking, and how modern rabbis did so too but no one checked to see if people obeyed. Sometimes we pass a law or use a hash tag and think we have solved a problem. We should check back to see if we really have solved the problem.
Silver Prices Have Dropped by One Third - I've talked before about the drop in silver prices due to inflation, but with the Chinese yuan and the stock market dropping like a rock, I am opening up the subject for discussion once again.
The Origin of the BayonetA flat-bladed knife about a foot long and a long handle has been around since the 1590s. Soldiers carry it on their belt. It is made in the town of Bayonne, France and thus the name "bayonet". This year soldiers have come up with a great idea. After firing their muskets, they shove the handle of the knife into the barrel and charge upon the enemy. In most instances, a charge with bayonets unnerves the other side and they are cut down mercilessly. By the 1660s the British will be using the bayonet. A ringed bayonet that leaves the barrel open to be fired again will be introduce in 1689 after a particularly gruesome defeat under enemy fire.    
OMG! No Smoking in Church! #IsNothingSacred?Smoking addiction is getting out of control. Soldiers are selling their weapons to buy smokes. Pope Urban the 8th has threatened to excommunicate anyone who uses snuff in church and he has prohibited his priests from smoking cigars during mass. Pope Innocent the 12th, who will succeed Pope Urban, will prohibit smoking entirely. Leaders should not issues orders that will not be obeyed. It weakens discipline. Centuries later, Pope Pius the 9th will have a tobacco factory built. Times change and then they change again.     
Silver Prices Have Dropped by One ThirdIn the last 100 years the price (or actually the value of what silver can buy) has dropped by one third. That is what has happened as silver has flooded the world market. Yet no adjustment for inflation has been made by government for taxes. Taxes remain fixed at a certain weight of silver so the amount of silver they take in has remained the same but the buying power of that silver has effectively dropped. In simple terms, if I owed the government 12 silver dollars in 1540, and today I owe 12 silver dollars, then the government can only buy 8 silver dollars (in 1540 dollars) worth of stuff with my 12 dollars due to inflation.
