Dedicated Outdoor Air Systems
Engineers at Pennsylvania State University have devised an air conditioning system that is more efficient than current standards and is highly resistant to dangerous airborne microbes such as anthrax. Because the Dedicated Outdoor Air System (DOAS) does not use recirculated air, a letter contaminated with anthrax would not spread throughout the building. A detailed technical overview of the concept is given on the DOAS home page, as well as an assessment of its benefits over traditional air cond

Manipula math with Java : Hyppocrates' lunar
This applet leads students through a proof of how the area of two lunar sections is equal to the area of a triangle inscribed in a semicircle. The illustration uses color-coded sections and gives students hints to help find the theorem. The proof uses the Pythagorean theorem to establish the relationship between the lunar sections and the triangle. A separate sequence of diagrams shows the outline of the proof to simplify it.
