	Foil (fluid mechanics) - Wikipedia, the free encyclopedia
		A foil is a surface designed to maximize lift (force generated perpendicular to the fluid flow) while minimizing drag (force generated in the direction of the fluid flow) in a given range of conditions.
		Foil design is strongly influenced by Bernoulli's principle, which states that high speed fluid flow results in lower pressure on surfaces parallel to the flow, and the related Coanda Effect, which states that a fluid stream will follow a surface that curves away.
		A good example of foils of this type are symmetric NACA 00xx foils, which have very low drag at zero angles of attack, and will generate lift equally well with positive or negative angles of attack.

		The equation states that the static pressure ps in the flow plus the dynamic pressure, one half of the density r times the velocity V squared, is equal to a constant throughout the flow.
		Thermodynamics is the branch of science which describes the macro scale properties of a fluid.
		The molecules within a fluid are in constant random motion and collide with each other and with the walls of an object in the fluid.

		Ongoing experiments aim to determine kinematics parameters for enhanced vehicle performance, often drawing inspiration from live fish: flapping foils yield high thrust and offer enhanced maneuvering capabilities; undulating body motions tend to decrease local near-body turbulence levels; and live fish reveal complex three-dimensional ring-like vortical structures in their wake.
		Hydrodynamic characteristics will be discussed for problems ranging from flapping foil propulsors, undulating hull-forms, and live fish swimming to the energy extraction from unsteady flows by flexible membranes.

	Obituaries: Dietrich Wolfgang Bechert - Physics Today August 2005
		The fluid mechanics community has lost Dietrich Wolfgang Bechert, retired chief scientist at the Institute for Turbulence Research of the German Aerospace Organization (now called DLR) in Berlin.
		Dietrich's passionate dedication to his work and his refusal to grant requests for quick results made him one of the preeminent experimentalists in fluid mechanics; he was also well versed in theory.
		Dietrich worked with the 3M Co on a riblet foil that was later used on a prizewinning America's Cup yacht (Cup rules have since barred its use) and tried on commercial airplanes.

		To understand the mechanisms of incapacitation and death caused by sharp force injury to the respiratory system, a brief explanation of the anatomy and mechanical function of this system will be helpful.
		Upon exhalation the process is reversed, generally through a passive mechanism produced by the elastic character of the lungs, chest wall, and abdomen.
		In the first installment of this essay modern forensic evidence indicated that exsanguination is the principal mechanism of death caused by stabbing and incising wounds, but that death by this means is seldom instantaneous; victims frequently capable of continued physical activity, even after being stabbed in the heart.

		Newtonian mechanics was an enormous success, but some difficulties started appearing in the latter part of the nineteenth century.
		Likewise, quantum mechanics was developed as a result to various paradoxes of Newtonian mechanics, like why electrons do not spiral into atomic nuclei and why a thermally-glowing object does not glow across the entire electromagnetic spectrum.
		Quantum mechanics was then applied to atoms in an initially kludgy "old quantum theory" fashion, but one that reached mathematical elegance in the formulations of Erwin Schr�dinger and Werner Heisenberg in the 1930's.
