Exact ratio is 256:135 but it is commonly referred to as 1.9:1 [32] [33] or 1.90:1 [34] [35] and sometimes 1.896:1. [36] Used by Diao Yinan's The Wild Goose Lake. [35] 2:1 = 18:9 Recently popularized by the Red Digital Cinema. Original SuperScope ratio, also used in Univisium. Used as a flat ratio for some American studios in the 1950s and ...
Only the fraction of the mass and energy labeled "atoms" is composed of elements. Only about 4% of the total mass of the universe is made of atoms or ions, and thus represented by elements. This fraction is about 15% of the total matter, with the remainder of the matter (85%) being dark matter. The nature of dark matter is unknown, but it is ...
A polymer (/ ˈ p ɒ l ɪ m ər / [4] [5]) is a substance or material that consists of very large molecules, or macromolecules, that are constituted by many repeating subunits derived from one or more species of monomers. [6]
A 95% confidence level does not mean that 95% of the sample data lie within the confidence interval. A 95% confidence level does not mean that there is a 95% probability of the parameter estimate from a repeat of the experiment falling within the confidence interval computed from a given experiment.

DNA is a long polymer made from repeating units called nucleotides. [ 6 ] [ 7 ] The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. [ 8 ] In all species it is composed of two helical chains, bound to each other by hydrogen bonds .
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells.
For the nominal horsepower to equal the actual power it would be necessary for the mean steam pressure in the cylinder during the stroke to be 7 psi (48 kPa) and for the piston speed to be that generated by the assumed relationship for paddle ships. [29] The French Navy used the same definition of nominal horse power as the Royal Navy. [29]
