Like da Vinci, Nikola Tesla had visions of creating flying machines. Since the Wright brothers had made the first practical, powered heavier-than-air flight in 1903, the development of airplane technology had proceeded rapidly. Fixed-wing aircraft, mainly biplanes, were widely used in World War I by both sides of the conflict. Never satisfied with standard airplanes, Tesla put his efforts into inventing a completely “new type of flying machine,” which he called a “helicopter-plane.” A precursor to what we today call a vertical takeoff and landing (VTOL) aircraft.
The invention consists of a new type of flying machine, designated “helicopter-plane”, which may be raised and lowered vertically and driven horizontally by the same propelling devices and comprises: a prime mover of improved design and an airscrew, both especially adapted for the purpose, means for tilting the machine in the air, arrangements for controlling its operation in any position, a novel landing gear and other constructive details, all of which will be hereinafter fully described.
The plane would look and act like no other plane. After rising from the ground vertically, the pilot would tilt the plane forward while his seat tilted to maintain an upright position and the wings repositioned horizontally. Besides the unique system for both vertical and horizontal propulsion, the helicopter-plane was also one of the first attempts to use turbine engines in rotor aircraft. Tesla may have been thinking of this technology for even more broadly useful purposes; he may have traveled to Detroit to market his design as a “flying automobile.”
Unfortunately, the aircraft idea was not further developed and became, in 1928 when he was seventy-two years of age, the last patent Tesla would receive.

The Philippines consists of 7,641 islands, although about 500 of them disappear at high tide. While the nation has growing industrial and service industries, about 30% of the labor force remains in agriculture, with rice as its biggest commodity.
My science education also didn’t stop with rice. Motag also showed us how to hack coconuts out of their outer husk using a sharp stick, then use another sharp stick to break up the coconut meat into flakes. We also got to taste coconut water and coconut milk. Coconut also played a role (no pun intended) as “paper” at the local toilet hole. Mixing coconut flakes with water makes a handy shampoo, while a coconut and leaves blend works great as a natural soap. These seemed to work better than the leaves sometimes used at the hole and sometimes to sandpaper the bark off trees (for which it worked way too well). Later I would enjoy the traditional coconut pie and 80-proof coconut wine/liquor.
On February 27, 1860, a tall, lanky lawyer from Illinois gave a speech at a place called Cooper Union in New York City. The speech would make Abraham Lincoln president. Sounds a bit hyperbolic to say such a thing, and there were many other factors that contributed to Lincoln’s success that election season, but the speech did more to make his name in eastern society than any other event.
William Wallace Lincoln, “Willie,” died of typhoid fever on February 20, 1862. President Abraham Lincoln and his wife Mary Lincoln were devastated. Willie’s younger brother Tad was also afflicted, but would live. This personal tragedy on top of the ongoing Civil War was almost too much to bear for both of them; Mary would never completely recover. But Willie’s death, and those of 700,000 soldiers during the Civil War, also ushered in advances in the embalming sciences.

For those who are local to the District of Columbia, we have monthly dinner meetings featuring well-known authors and Lincoln scholars, run at least one Civil War battlefield tour a year, have an engaging monthly book study group, and a host of other events and meetings. The Lincolnian newsletter comes out quarterly and includes news about the group as well as scholarly articles about Abraham Lincoln.
Although he was the last of seven children, Thomas Alva Edison was born into a largely empty household. February 11, 1847, was a cold, snowy night in the tiny village of Milan, Ohio, not far from the shores of Lake Erie. Edison’s mother, Nancy, who seemed always to be wrapped in black mourning garb, was eager to have more children to replace those who had not survived. One son, Carlile, died in 1842, when he was only 6 years old. A second son, 3-year-old Samuel Ogden, perished a year later while Nancy was pregnant with daughter Eliza. Eliza also lived only three years, passing away in late 1847, when Thomas was still an infant.
Most people of heard of Doris Kearns Goodwin from her bestselling book, Team of Rivals, about Abraham Lincoln picking many of his political rivals to key cabinet positions. Initially well sold, it got a huge boost after then-candidate Barack Obama was seen carrying it on the campaign trail prior to his 2008 election, then again when Obama picked his rival Hillary Clinton to be Secretary of State, much like Lincoln put William Seward in that position. Another boost came from Steven Spielberg’s movie, Lincoln, which was based on a tiny part of Goodwin’s book.
