  • 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.

  • This is an X-ray of a child's boot with electronics.  The batteries are mounded in the sole of the boot and the lights are placed along the sides.  A motion detector in the sole controls the flashing of the lights (light emitting diodes) as the child walks.  These types of boots rise many security issues when a child travels with them on an airplane.  The layout of the electronics and batteries is almost identical to a terrorist bomb placed in the sole of the boot.

  • An electrical spark created when a sheet pf photographic film is placed between two high voltage electrodes. Initially, the film builds up a charge on the surface and acts like as a capacitor. At a certain potential voltage the film, which is a dielectric material, breaks down and allows electrons to flow. The flowing electrons superheat the air resulting in an electrical spark which is recorded in the film emulsion. These are often called Lichtenberg Figures after the German physicist Georg Christoph Lichtenberg, who originally discovered and studied them.

  • Crookes tube. Invented by William Crookes (1832 - 1919) in the late 19th century.  This apparatus was used to investigate the path taken by electrons or cathode rays as they were called then.   In this experiment the electrons are emitted from a central disc towards the glass.  As the electrons collide with the glass they fluoresce.   The metal star pattern blocks the electrons causing a shadow on the glass.  Crookes showed from the resulting shadow that electrons travel in straight lines.  The overall glow of the apparatus is caused by the excitation of the remaining gas molecules in the tube.

  • Colored scanning electron micrograph (SEM) of the head of a bedbug (Cimex sp.). It has a compound eye (grey) on each side of its head. Antennae protrude on either side of its mouth. The stylet, a piercing mouthpiece (red, center,) is used to suck blood from warm-blood animals, including humans. Bedbugs are generally only active at night, hiding in crevices in walls and furniture and in bedding during the day. Although they do not transmit disease, their saliva can cause itchy swellings on the skin.

  • Thermophilic bacteria . Collected in the summer of 2012 in 60C water in Yellowstone National Park, Wyoming USA.  This scanning electron micrograh (SEM) was shot at 6,580X magnification and the filed of view is 20 um.  This type of bacteria is adapted to thrive at high water temperatures and is currently the focus of biological researchers.   Bacteria that can live in these extreme conditions are called thermophiles or extremophiles.

  • Scanning electron microscope image of the dark flower in the center of a Queen Anne's Lace ( Daucus carota) Flower. Queen Anne's Lace , is also known as Wild Carrot or Bird's Nest . An introduced weed that is abundant throughout much of temperate North America east of the Sierras. It is the wild form of the domesticated garden carrot.  The USDA has listed it as a noxious weed. The calibration bar is 200um or .2mm.  This image was collected at 231x..The luna moth has one of the most sensitive antenna of any insect.  The males antenna has the sole purpose of smelling out a female for mating.

  • This image of an electrical discharge was made by placing a block of Lucite in the 6 megavolt (6Mv) electron beam of a linear accelerator. The Lucite gained a tremendous electrical charge when a grounded electrode was placed near it. The current flowing to ground melted the Lucite, leaving a record of the current flow. This fern-like fractal structure is quite common in electricity.

  • A scanning electron microscope image of the football shaped bract of the female  cannabis (Cannabis sativa) flower. The oval bract structure houses the stigma and is responsible for producing seeds when the flower has been pollinated. This bract structure is also the location of the highest concentration of cannabinoid compounds on the plant.  This site is also the location of the highest concentration of THC. There are a number of different types of cell structures called trichomes in this image. The thorn-like trichomes use a physical defense while the circular glandular trichomes use chemical defense. Combined, these defenses keep insects and animals from eating the plant. Each circular glandular trichome is 50 um in diameter in this image. The filed of view of this image is 3 mm wide.
