Kleiber's plot comparing body size to metabolic rate for a variety of species. [1] Kleiber's law, named after Max Kleiber for his biology work in the early 1930s, is the observation that, for the vast majority of animals, an animal's metabolic rate scales to the 3⁄4 power of the animal's mass. [2] More recently, Kleiber's law has also been ...
Four Thirds logo. The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) design and development. [1] Four Thirds refers to both the size of the image sensor (4/3") as well as the aspect ratio (4:3). The Olympus E-1 was the first Four Thirds DSLR, announced and released in 2003.
In digital photography, the image sensor format is the shape and size of the image sensor. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. Because the image sensors in many digital cameras are smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras ...
A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a / b or , where a and b are both integers. [9] As with other fractions, the denominator (b) cannot be zero. Examples include 1 2 , − 8 5 , −8 5 , and 8 −5 .

In mathematics, the Farey sequence of order n is the sequence of completely reduced fractions, either between 0 and 1, or without this restriction, [ a] which when in lowest terms have denominators less than or equal to n, arranged in order of increasing size. With the restricted definition, each Farey sequence starts with the value 0, denoted ...
Common gauges are 7-1/2" (Western US) and 7-1/4" (Eastern US & rest of the world), 5", and 4-3/4". Smaller live steam gauges do exist, but as the scale gets smaller, pulling power decreases. One of the smallest gauges on which a live steam engine can pull a passenger is the now almost defunct 2 + 1 ⁄ 2 -inch gauge.
Micro Four Thirds system. The Micro Four Thirds system (MFT or M4/3 or M43) (マイクロフォーサーズシステム, Maikuro Fō Sāzu Shisutemu) is a standard released by Olympus Imaging Corporation and Panasonic in 2008, [1] for the design and development of mirrorless interchangeable lens digital cameras, camcorders and lenses.
