  • The inside of a magnetron removed from a microwave oven.  The magnetron is a device that creates microwave radiation. A magnetron consists of an electron tube surrounded by a magnet. As electrons are released from the heated cathode they are forced to take a spiral path to the anode by the magnetic field, creating microwaves. This magnetron creates a microwave radiation that is the same frequency as a water molecule vibrates.  When water is exposed to just the right frequency, the water molecules will gain kinetic energy and become hotter.

  • A scanning electron microscope image of the leaf of the lavender plant (Lavandula augustifolia ).  The branching cells give added protection from insects.  The pillow shaped structure produces the aromatic sent that gives lavender it characteristic smell.

  • The electrostatic field lines around a point charge and a cylinder.   The electric fields are shown by placing the two charged objects in a pan filled with cooking oil and pepper flakes.  The pepper flakes align in the electric field and allow visualization of the field.  In this image the left point is charged to -30,000 volts while the right ring has a potential of + 30,000 volts.  This image is part of a series showing different charging conditions.  Of special importance is the lack of fields showing inside the cylinder.  This is the classic case of no electrical fields inside an electrical conductor.  In this image the cylinder acts as a Faraday cage and shields the enclosed area from any external electrical fields..

  • An X-ray of Yellow Perch (Perca flavescens). The Yellow Perch (Perca flavescens) is a favorite for anglers due to its firm white flesh when cooked. Easily caught in all seasons, this is a popular sport fish. Perch prefer a diet of young fish and aquatic insects and can reach a length of up to 30 centimeters and a mass of 2 kilograms.
