Thanks to Ben Franklin, for his flying kite on June 10 1752, for his 1st setting up library, fire dept, hospital..

It is in 1752, Benjamin Franklin conducted an experiment in connection with electricity charged clouds. He flew a homemade kite during a thunderstorm. The kite was made of a silk cloth mounted on a wooden cross, with about one foot of iron wire protruding above the kite. A key was tied to the end of metal string connected with the kite and the other end of the key was tied to a silken ribbon which Benjamin held while flying the kite. A bolt of lightning struck the kite wire and traveled down to the key causing a spark. This proved that lightning is electricity from charged clouds that can be brought to earth. There was a time when high-rise buildings were destroyed quite frequently by lightning. Benjamin Franklin invented lightning rod for the safety of buildings.

The iconic Golden Gate Bridge in San Francisco, California, turned 72 years old on Wednesday. The Golden Gate Bridge is one of the most beautiful, and most photographed, bridges in the world. Its 4,200 foot long main suspension span was a world record that stood for 27 years. It is still the second longest in the United States after the Verrazano-Narrows Bridge which links Staten Island to Brooklyn in New York. The bridge's two towers rise 746 feet making them 191 feet taller than the Washington Monument. read more »
Vauban's streets are nearly "car-free": on outskirts of Freiburg, Germany - suburban pioneers give up their cars

(quote)
VAUBAN, Germany - Residents of this upscale community are suburban pioneers, going where few soccer moms or commuting executives have ever gone before: they have given up their cars.
Street parking, driveways and home garages are generally forbidden in this experimental new district on the outskirts of Freiburg, near the French and Swiss borders. Vauban’s streets are completely “car-free” - except the main thoroughfare, where the tram to downtown Freiburg runs, and a few streets on one edge of the community. Car ownership is allowed, but there are only two places to park — large garages at the edge of the development, where a car-owner buys a space, for $40,000, along with a home. As a result, 70 percent of Vauban’s families do not own cars, and 57 percent sold a car to move here. Vauban, completed in 2006, is an example of a growing trend in Europe, the United States and elsewhere to separate suburban life from auto use, as a component of a movement called “smart planning.”

"Up" by Disney/Pixar becomes the first animated movie ever to open the Cannes Film Festival (2009)

(quote)
The tenth Pixar movie, "Up", has the honor of being the first animated picture ever to open a Cannes festival. Carl Fredricksen (voiced by Ed Asner) is a 78-year-old widower who has always longed to visit the mythical lost worlds of South America. When developers conspire to pack him off to a nursing home, he ties up thousands of balloons to the roof of his house and flies away to fulfill that dream. Alongside him, rather unexpectedly, is an 8-year-old Wilderness Explorer named Russell (Jordan Nagai), a peppy naïf who offsets his grousier temperament.
It's utterly delightful, certain to appeal to audiences young, old and all points in between. Cannes audiences are notoriously vocal. They'll whistle if they're unhappy -- a French version of a boo -- and a movie that doesn't meet the audience's high standards will be treated to the repeated "whop" sounds of theater seats banging shut as patrons leave. "Up," on the other hand, received little but cheers.
