  2. Kinetoscope - Wikipedia

    en.wikipedia.org/wiki/Kinetoscope

    Kinetoscope production had been delayed in part because of Dickson's absence of more than eleven weeks early in the year with a nervous breakdown. [41] Hendricks, referring to various accounts, including ones in the July 22 Science and the October 21 Scientific American , argues that one Kinetoscope did make it to the fair. [ 42 ]

  3. Chemical kinetics - Wikipedia

    en.wikipedia.org/wiki/Chemical_kinetics

    Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate.

  4. Chemistry - Wikipedia

    en.wikipedia.org/wiki/Chemistry

    Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

  5. History of the Kinetograph, Kinetoscope, and Kinetophonograph

    The mechanics of primordial motion picture cameras and exhibition are explained, [4] with eponymous emphasis given to the kinetograph, the kinetoscope, and the kinetophonograph. Dickson worked with Edison on the development of these devices, which respectively capture pictures on film, play films back, and combine picture with sound. [ 5 ]

    is an alkaline solution of potassium permanganate; used in organic chemistry as a qualitative test for the presence of unsaturation, such as double bonds; N-Bromosuccinimide: used in radical substitution and electrophilic addition reactions in organic chemistry. Also acts as a mild oxidizer to oxidize benzylic or allylic alcohols.

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

    This was the first example of projected animation, [4] demonstrated in 1853; [5] it is also described as the combination of the zoetrope with the magic lantern. [6] It was called the kinetoscope, [7] a term later used by Thomas Edison (see kinetoscope). He applied it to lecture on ballistics. [8]

    For example, mass is an intrinsic property of any physical object, whereas weight is an extrinsic property that depends on the strength of the gravitational field in which the object is placed. Applications in science and engineering
