Speed of Sound Table Chart 
Speed of Sound table chart including Speed of Sound at a known temperature and density of air, Speed of Sound vs Density of Air. 

Air Density Equations and Calculator 
The following is a Air Density and Specific Weight Equations and Calculator. Variables required include Temperature, Humidity, Barometer and altitude 

Leidenfrost effect 
The Leidenfrost effect is a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer keeping that liquid from boiling rapidly. 

Resultant Vector Physics 
A resultant is a single vector which represents the combined effect of two or more othervectors (called components). The components can be determined either graphicallyor by using trigonometry. 

Vector Quantities Physics 
A vector quantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities. 

Ray Optics Simulation and Calculator 
This application will simulate reflection and refraction of light with optics such as: A single ray of light defined by two points, A parallel beam of rays emerges from a linesegment, with density controlled by the "Ray density" slider, A mirror whose shape is part of a circle, which is defined by three points., Glass with any shapes constructed from line segments and circular arcs, including prisms and "spherical" lenses., etc.
