Hello
I left my birth town of Sofia in 1996 and I am currently located in Paris. My interests include almost every musical style, motorsport and of course medicine which also happens to be my job. You may also see me trying to correct some inaccuracies in articles concerning Bulgaria.

A male Mallard in mid-flight. The fundamentals of bird flight are similar to those of aircraft. Lift force is produced by the action of air-flow on the wing, which is an airfoil. This occurs because the air has a lower air pressure just above the wing and higher pressure below. When a bird flaps its wings continue to develop lift but they also create an additional forward and upward force, thrust, to counteract its weight and drag. Photo credit: Alan D. Wilson |
