Webster's 1913 Dictionary
 
 Definition: 
  1. \H\ ([=a]ch),
    the eighth letter of the English alphabet, is classed among
    the consonants, and is formed with the mouth organs in the
    same position as that of the succeeding vowel. It is used
    with certain consonants to form digraphs representing sounds
    which are not found in the alphabet, as sh, th, [th], as in
    shall, thing, [th]ine (for zh see [sect]274); also, to modify
    the sounds of some other letters, as when placed after c and
    p, with the former of which it represents a compound sound
    like that of tsh, as in charm (written also tch as in catch),
    with the latter, the sound of f, as in phase, phantom. In
    some words, mostly derived or introduced from foreign
    languages, h following c and g indicates that those
    consonants have the hard sound before e, i, and y, as in
    chemistry, chiromancy, chyle, Ghent, Ghibelline, etc.; in
    some others, ch has the sound of sh, as in chicane. See
    {Guide to Pronunciation}, [sect][sect] 153, 179, 181-3,
    237-8.
    
    Note: The name (aitch) is from the French ache; its form is
          from the Latin, and this from the Greek H, which was
          used as the sign of the spiritus asper (rough
          breathing) before it came to represent the long vowel,
          Gr. [eta]. The Greek H is from Ph[oe]nician, the
          ultimate origin probably being Egyptian. Etymologically
          H is most closely related to c; as in E. horn, L.
          cornu, Gr. ke`ras; E. hele, v. t., conceal; E. hide, L.
          cutis, Gr. ky`tos; E. hundred, L. centum, Gr.
          'e-kat-on, Skr. [.c]ata.
    
    {H piece} (Mining), the part of a plunger pump which contains
       the valve.
    
    
  2. \H\ (h[add]). (Mus.)
    The seventh degree in the diatonic scale, being used by the
    Germans for B natural. See {B}.

 Definition: 

1. A simple markup language intended for quick conversion of existing text to hypertext.

2. A method of marking common words to call attention to the fact that they are being used in a nonstandard, ironic, or humorous way. Originated in the fannish catchphrase "Bheer is the One True Ghod!" from decades ago. H-infix marking of "Ghod" and other words spread into the 1960s counterculture via underground comix, and into early hackerdom either from the counterculture or from SF fandom (the three overlapped heavily at the time). More recently, the h infix has become an expected feature of benchmark names (Dhrystone, Rhealstone, etc.); this follows on from the original Whetstone (the name of a laboratory) but may have been influenced by the fannish/counterculture h infix.

 Definition: 
  1. The heat in a system.
  2. Hydrogen is a gas element which has an atomic number of 1 and an atomic weight of 1.0079. It combines with oxygen to form water (H20) and is present in all organic compounds. A few types of bacteria can metabolize atmospheric hydrogen (H2). Hydrogen gas itself is not poisonous, but when it mixes with air it can easily ignite or explode.

    Hydrogen was discovered by Henry Cavendish in 1766 and was named by Lavoisier. There are two main isotopes of hydrogen: deuterium (2H) and tritium (3H, which is radioactive and is used in some glow-in-the-dark paints and as a tracer in biological studies).
