The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on ...

A radar altimeter measures altitude above the terrain beneath an aircraft as opposed to a barometric altimeter which provides the distance above a pre-determined datum, usually sea level. Radar is the underpinning principle of the system. Radio waves t...

A pH meter, typically consisting of a special measuring probe connected to an electronic meter, is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid. The probe measures pH as the hydrogen ion activity that surrounds a ...

The fortune cookie, made of flour, sugar, vanilla, and oil, is a crisp cookie with a fortune wrapped inside. Generally these fortunes are words of faux wisdom or a vague prophecy possibly including a Chinese phrase with translation. Fortune cookies are...

A flyswatter, usually consisting of a small rectangular sheet of flexible material, is a handheld device for smashing flies and other insects. The material is vented, thus reducing wind drag making it move faster in order to hit the target. The beginni...

Fiberglass consists of numerous extremely fine fibers of glass. Although experimented with throughout history actual glass fibers were not mass produced until the invention of finer machine tooling. A dress with glass fibers was first worn in 1893 by...

Cotton swabs, made of a small wad of cotton wrapped around both ends of a short rod, are commonly used in a variety of applications including first aid, cosmetics application, cleaning, and arts and crafts. Leo Gerstenzang created the cotton swab in th...

A mercury arc valve converts high-voltage or high-current alternating current into direct current. It is an electrical rectifier often used to provide power for industrial motors, electric railways, streetcars, and electric locomotives. Peter Coope...

The Kinetoscope is an early motion picture device although not a movie projector. It is designed to be viewed by an individual through a window of a cabinet housing its components. It works by creating the illusion of movement by conveying a strip of p...

The bolometer, invented in 1878 by Samuel Pierpont Langley, measures the energy of incident electromagnetic radiation. It consists of an absorptive element connected to a heat sink through a thermal link. The absortive element raises its temperature ab...

Photographic film is a sheet of plastic coated with an emulsion containing light-sensitive silver halide salts that when exposed to light it forms a visible image. Through film developing, a chemical process applied to the film, a visible image is crea...
