Flight Record: Songbirds Trek 9,000 Miles to Africa. Tiny songbirds weighing no more than two tablespoons of salt apparently globe-trot regularly from the Arctic to Africa, crossing either Asia or the Atlantic to do it, scientists find.
Researchers had known the northern wheatear (Oenanthe oenanthe) had one of the largest ranges of any songbird in the world, with breeding grounds extending from Alaska and extreme northwestern Canada across northeastern Canada and into Europe and Asia. The insect-eating birds apparently leave the Arctic region of the Western Hemisphere for the winter, but it was a mystery as to precisely where they migrated. Now, using light-sensing tags strapped onto these songbirds, investigators find these birds overwinter in sub-Saharan Africa.
Their one- to three-month voyages can reach distances of up to 9,000 miles (14,500 kilometers), covering up to 180 miles (290 km) per day. The songbirds apparently follow two routes across ocean and desert from the Arctic to Africa. Online Dictionary Search Results. Top 6 Sites that Inspire and Educate.

Amputation Knife (1700s) Knives used for amputations during the 18th century were typically curved, because surgeons tended to make a circular cut through the skin and muscle before the bone was cut with a saw. By the 1800s, straight knives became more popular because they made it easier to leave a flap of skin that could be used to cover the exposed stump. Amputation Saw (1600s) While some surgeons chose to flaunt their wealth with elaborately decorated saws like this, the crevices in the intricate engravings proved to be a breeding ground for germs.

The mere act of observation can completely change the outcome of an event! Before I get too ahead of myself, you need to watch the video below to understand: (Forgive the corny cartoon character explaining the concept — at least he knows his stuff) Recap: When a camera observed the electrons, they acted as particles. However, when the no equipment was used to observe the electrons, they acted as waves and particles simultaneously.
