The Rotary Dial Telephone and User Interface Errors
The current telephone system consists of switchboards and human operators. You "ring up" the operator (also called "Central") by turning a crank and then asking to be connected to "Bob Jones" or to a telephone number such as "KLondike-55311". Then the operator uses a plug-in connector to physically connect your phone to the proper circuit . Of course mistakes can be made and a little bit of corruption can occur. A local undertaker suspects that the operator is diverting calls from his business to a competitor. Since this sort of thing would be difficult to prove, he decides to solve the problem by bringing power to the people. He develops a direct connect system where you select combinations of letters and numbers by using a dial. Your selection automatically routes your call without human intervention. This is called direct-dialing and it seems like a great idea, but Bell Telephone won't adopt the rotary dial for another 28 years.  
The Mafia Puts a Hit on the Chief of Police
Italian immigrants have done well in Louisiana, working their way into the fruit business, and loading down at the docks. Their political influence has also grown. For example, Joseph Macheca is an Italian fruit merchant. He bought real estate in New Orleans during an economic downturn and now he is well off and politically active. He is part of the Regular Democrats which are made up of Irish and other white ethnics such as the Italians. The Mayor is a Reformer Democrat. The Reformers are elitists who are cultivating the black Republican vote. The police force has been in bad shape so a few years ago the Mayor appointed David Hennessy as Chief of Police to fix the problem. He has done a reasonable job, but there is a rumor that he supports one of the Mafia families down at the docks. As Hennessy is walking home, a shot rings out. He goes down and then whispers, "The Dagoes did it!"... meaning the Italians. (This is the equivalent of calling a Mexican, "Diego" but with the intent to dismiss or humiliate.) Hennessy dies the next day. About 100 Italians are arrested including a large number of the Mayor's political opponents. (Imagine that.) 19 men are charged with murder. The newspapers have already passed judgement, so after the first few "not guilty" verdicts come through, the Mayor's campaign manager organizes a lynch mob of 10,000. He leads a smaller armed force into the Parish prison and shoots 11 men dead, including Joseph Macheca, the fruit merchant. Then the mob goes home. Total elapsed time... 1 hour. No charges are brought. The Mayor is unrepentant. This is the single largest mass lynching in US history.        
The Tesla Coil for the Wireless Telegraph
WARNING: I am about to explain how a wireless telegraph works. In a few moments every Ham operator in the world will be tempted to strangle me, so if transmission is suddenly lost, you'll know why.
Radio technology of the 1890s requires an actual spark of electricity to generate radio static across a range of frequencies. If you have ever listened to a radio during a lightening storm, you will hear static each time a lightening bolt strikes the ground. The lightening bolt is generating radio static across a wide range of frequencies, so if we could create our own lightening and then filter out the other frequencies, we could transmit a message in Morse Code without need of the wire connecting the two stations. Such a transmitter would be "wireless." A radio receiver acts like a tuning fork. It resonates or is tuned to the same frequency. The receiver then translates those small bursts of static into something that humans can understand. The artificial lightening device used in the transmitter is called a spark-gap. (FYI, this is also why radio operators have the nickname of "Sparks".) I know it sounds crazy but for years after vacuum tube radios were the norm, naval vessels kept their spark-gap radios in reserve. The spark-gap transmitter is so dead simple that even an officer couldn't screw it up. (Wait. Did I say that out loud?) The spark-gap produces radio waves but Nicola Tesla has figured out a different way to produce the required sparks using AC power and two air-core transformers in very close proximity. This is the Tesla Coil. It's like using a shotgun as your master key. It gets the job done.

In January 1891, the knife received the official designation Modell 1890. The knife had a blade, reamer, can-opener, screwdriver, and grips made out of dark oak wood that some say was later partly replaced with ebony wood. At that time no Swiss company had the necessary production capacity, so the initial order for 15,000 knives was placed with the German knife manufacturer Wester & Co. from Solingen, Germany. These knives were delivered in October 1891.”

These models allowed Langley to test nearly 100 different aircraft configurations, but he eventually gave up this effort after learning little from the frail, breakable models. He then pursued a new and more sophisticated approach using steam-powered sub-scale flying machines that he called 'aerodromes' (from the Greek aerodromoi, or 'air runner'). Seven different aerodrome designs, numbered 0 to 6, were constructed, and Aerodrome no. 5 proved to be the most successful. Weighing in at 26 lb, the design featured twin tandem wings with highly cambered airfoils and two propellers driven by a 1-hp steam engine.”
