  2. Telestrator - Wikipedia

    en.wikipedia.org/wiki/Telestrator

    Example of how a telestrator might annotate a medical image shared during a telemedicine session. The telestrator was invented by physicist Leonard Reiffel , who used it to draw illustrations on a series of science shows he did for public television 's WTTW in Chicago in the late 1950s.

  3. Finite sphere packing - Wikipedia

    en.wikipedia.org/wiki/Finite_sphere_packing

    An arrangement in which the midpoint of all the spheres lie on a single straight line is called a sausage packing, as the convex hull has a sausage-like shape.An approximate example in real life is the packing of tennis balls in a tube, though the ends must be rounded for the tube to coincide with the actual convex hull.

  4. Amateur chemistry - Wikipedia

    en.wikipedia.org/wiki/Amateur_chemistry

    Amateur chemistry or home chemistry is the pursuit of chemistry as a private hobby. [1] Amateur chemistry is usually done with whatever chemicals are available at disposal at the privacy of one's home. It should not be confused with clandestine chemistry, which involves the illicit production of controlled drugs.

    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 ...

  8. Excess property - Wikipedia

    en.wikipedia.org/wiki/Excess_property

    By definition, excess properties are related to those of the ideal solution by: z E = z − z IS {\displaystyle z^{E}=z-z^{\text{IS}}} Here, the superscript IS denotes the value in the ideal solution, a superscript E {\displaystyle E} denotes the excess molar property, and z {\displaystyle z} denotes the particular property under consideration.

  9. Optical rotation - Wikipedia

    en.wikipedia.org/wiki/Optical_rotation

    For example, nine of the nineteen L-amino acids naturally occurring in proteins are, despite the L- prefix, actually dextrorotary (at a wavelength of 589 nm), and D-fructose is sometimes called "levulose" because it is levorotary. The D- and L- prefixes describe the molecule as a whole, as do the (+) and (−) prefixes for optical rotation.
