“Igor Sikorsky (May 25, 1889 – October 26, 1972), born Igor Ivanovich Sikorsky was a Russian American pioneer of aviation in both helicopters and fixed-wing aircraft. He designed and flew the world's first multi-engine fixed-wing aircraft, the Russky Vityaz in 1913, and the first airliner, Ilya Muromets, in 1914. After immigrating to the United States in 1919, Sikorsky founded the Sikorsky Aircraft Corporation in 1923, and developed the first of Pan American Airways' ocean-conquering flying boats in the 1930s. In 1939 Sikorsky designed and flew the Vought-Sikorsky VS-300, the first viable American helicopter, which pioneered the rotor configuration used by most helicopters today. Sikorsky would modify the design into the Sikorsky R-4, which became the world's first mass-produced helicopter in 1942”. – Wikipedia

Randy Scott Slavin's photography is surrealism based in reality. His work portrays land and cityscapes in a 360 degree view, a perspective closer to that of the human eye than a 2D photograph, he says. Slavin's "Alternate Perspectives" is a series of photographs of a single location or landmark pieced together to create a 360 degree perspective in a flat image. The results are whimsical, and occasionally eerie, scenes that reflect the portion and scale of Slavin's surroundings when he took the photo.

The President tree is the name of a giant sequoia located in the Giant Forest of Sequoia National Park in the United States, east of Visalia, California. The tree is believed to be at least 3,200 years old.
The tree was named after President Warren G. Harding in 1923. Nearby trees include Chief Sequoyah, the 27th largest giant sequoia in the world, and the Congress Group, two dense stands of medium sized sequoias that represent the "House" and "Senate".
