Nikola Tesla was born July 10, 1856 and passed away on January 7, 1943.
Nikola Tesla was a Serbian American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.
Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant. His work in the formative years of electric-power development was involved in a corporate alternating current/direct current “War of Currents” as well as various patent battles. He became a naturalized US citizen in 1891.
Tesla went on to pursue his ideas of wireless lighting and electricity distribution in his high-voltage, high-frequency power experiments in New York and Colorado Springs and made early (1893) pronouncements on the possibility of wireless communication with his devices. He tried to put these ideas to practical use in an ill-fated attempt at intercontinental wireless transmission, his unfinished Wardenclyffe Tower project. In his lab, he also conducted a range of experiments with mechanical oscillators/generators, electrical discharge tubes, and early X-ray imaging. He also built a wireless controlled boat, one of the first ever exhibited.
Tesla was renowned for his achievements and showmanship, eventually earning him a reputation in popular culture as an archetypal “mad scientist”. His patents earned him a considerable amount of money, much of which was used to finance his own projects with varying degrees of success. He lived most of his life in a series of New York hotels through his retirement. Tesla died on 7 January 1943. His work fell into relative obscurity after his death, but in 1960, the General Conference on Weights and Measures named the SI unit of magnetic flux density the tesla in his honor.

Happy Summer Solstice for those in the northern hemisphere.
The summer solstice occurs when the tilt of a planet’s semi-axis, in either the northern or the southern hemisphere, is most inclined toward the star that it orbits. Earth’s maximum axial tilt toward the Sun is 23° 26′. This happens twice each year, at which times the Sun reaches its highest position in the sky as seen from the north or the south pole.
The summer solstice occurs during a hemisphere’s summer. This is the northern solstice in the northern hemisphere and the southern solstice in the southern hemisphere. Depending on the shift of the calendar, the summer solstice occurs some time between June 20 and June 22 in the northern hemisphere and between December 20 and December 23 each year in the southern hemisphere.
When on a geographic pole, the Sun reaches its greatest height, the moment of solstice, it can be noon only along that longitude which at that moment lies in the direction of the Sun from the pole. For other longitudes, it is not noon. Noon has either passed or has yet to come. Hence the notion of a solstice day is useful. The term is colloquially used like midsummer to refer to the day on which solstice occurs. The summer solstice day has the longest period of daylight – except in the polar regions, where daylight is continuous, from a few days to six months around the summer solstice.
Worldwide, interpretation of the event has varied among cultures, but most recognize the event in some way with holidays, festivals, and rituals around that time with themes of religion or fertility.
Solstice is derived from the Latin words sol (sun) and sistere (to stand still).

Please Help Save Net Neutrality.
PLEASE EVERYONE. DO THIS OR YOU WILL REGRET IT!!
CONGRATULATIONS everybody! We only have 7 days to fight the FCC & the repeal of #NetNeutrality! Thanks to John Oliver there’s a SUPER easy way to do this. Do you enjoy Netflix? Do you find yourself spending too much time on FB? If net neutrality goes away, our Internet bills go up and we give power to companies like Comcast and Spectrum to control what information we can access.
Here’s what you can do – takes less than a minute.
1. Go to gofccyourself.com
(the shortcut John Oliver made to the hard-to-find FCC comment page)
2. Click on the 17-108 link (Restoring Internet Freedom)
2. Click on “+Express” under Filters on the left side of the screen (in the bottom of the Docket 17-108 box).
3. Be sure to hit “ENTER” (or return) on your keyboard after you put in your name, so it registers. (They make it a tad tricky there.)
4. In the comment section write, “I strongly support net neutrality backed by Title 2 oversight of ISPs.”
5. Click to Review, then Submit, done. – Make sure you hit submit at the end!
Copy & paste to repost this, pls., rather than ‘Share’-ing, as it will be seen by more people. (And if the “CONGRATULATIONS everybody” at the beginning of this post confused you as it did me, it’s utilizing a Facebook algorithm to make sure this post appears on more of your friends’ feeds).
This is one of those posts that it’s better to copy and paste than to share.
