  • Interesting fact: Hard Bean means the coffee was grown at an altitude above 5000 feet.
    • Hardness (Min) The cohesion of the particles on the surface of a body, determined by its capacity to scratch another, or be itself scratched; -- measured among minerals on a scale of which diamond and talc form the extremes.
    • Hardness (Chem) The peculiar quality exhibited by water which has mineral salts dissolved in it. Such water forms an insoluble compound with soap, and is hence unfit for washing purposes.
    • Hardness The quality or state of being hard, literally or figuratively. "The habit of authority also had given his manners some peremptory hardness ."

  • Interesting fact: Human teeth are almost as hard as rocks.
    • n hardness The state or quality of being hard, in any of the senses of that word; solidity; density; difficulty of comprehension, accomplishment, control, or endurance; obduracy; harshness; severity; inclemency; adversity; roughness; uncomeliness; want of sensibility.
    • n hardness Specifically That quality in fountain-water which is imparted by the presence in excess of earthy salts, especially calcium sulphate.
    • n hardness In medicine, that quality of the pulse which is due to tension of the artery, which in this condition does not readily yield to the pressure of the finger.
    • n hardness In art and music, harshness or coldness of execution; unsympathetic treatment, as of a tone or the details of a picture; want of feeling in performance.
    • n hardness In mineralogy, the comparative capacity of a substance to scratch another or be scratched by another; the quality of bodies which enables them to resist abrasion of their surfaces. Scales have been constructed in which a set of standard bodies are arranged and numbered, and other bodies are referred to this scale in respect of hardness. The diamond is the hardest body known, and in the scale of Mohs its hardness is indicated by the number 10. The scale is as follows: Talc, 1; rock-salt, 2; calcite, 3; fluor-spar, 4; apatite, 5; feldspar, 6; rock-crystal, 7; topaz, 8; corundum, 9; diamond, 10.
    • n hardness Water, as found in nature, containing salts of lime or magnesia or both of these in considerable quantity, is said to be hard; it curdles or precipitates soap bv forming insoluble lime or magnesia salts of the fatty acids. Any lime or magnesia present in the condition of carbonate is held in solution by carbonic acid, and if this latter is driven off as carbon-dioxid gas by boiling the water, the earthy carbonates are precipitated, so that the water is to this extent softened. The part of the original hardness which is thus removable by boiling is called temporary hardness. The part due to calcium or magnesium in the condition of chlorid or sulphate is not thus removable, and is called permanent hardness. The sum of the temporary and permanent hardness constitutes the total hardness. Hardness is frequently stated in degrees, each degree representing hardness equivalent to that caused by 1 grain of calcium carbonate in 1 imperial gallon of water; or, now more commonly, 1 part of calcium carbonate in 1,000,000 parts of water.

The first is that “reconstructing” the object from class C may be hard, and the second is that sampling approximately uniform random satisfying assignments from the reconstructed object may be hard.

The first example of such effects due to hard-photon bremsstrahlung is given by the O(α) NLO corrections arising from the emission of a hard acol linear photon by the initial state, because hard collinear photons are already taken into account by the leading logarithmic (LL) prescriptions (see Appendix A).

The former arise from the configurations where a hard photon is radiated off in the direction of incoming electron or positron in association with a large-angle, acollinear additional hard photon, and provide corrections of the order of α2L.
