| burst | 1. To fly apart or in pieces; of break open; to yield to force or pressure, especially to a sudden and violent exertion of force, or to pressure from within; to explode; as, the boiler had burst; the buds will burst in spring. "From the egg that soon Bursting with kindly rupture, forth disclosed Their callow young." (Milton) Often used figuratively, as of the heart, in reference to a surcharge of passion, grief, desire, etc. "No, no, my heart will burst, an if I speak: And I will speak, that so my heart may burst." (Shak) 2. To exert force or pressure by which something is made suddenly to give way; to break through obstacles or limitations; hence, to appear suddenly and unexpecedly or unaccountably, or to depart in such manner; usually with some qualifying adverb or preposition, as forth, out, away, into, upon, through, etc. "Tears, such as angels weep, burst forth." (Milton) "And now you burst (ah cruel!) from my arms." (Pope) "A resolved villain Whose bowels suddenly burst out." (Shak) "We were the first that ever burst Into that silent sea." (Coleridge) "To burst upon him like an earthquake." (Goldsmith) Origin: OE. Bersten, bresten, AS. Berstan (pers. Sing. Berste, imp. Sing. Baerst, imp. Pl. Burston, p.p. Borsten); akin to D. Bersten, G. Bersten, OHG. Brestan, OS. Brestan, Icel. Bresta, Sw. Brista, Dan. Briste. Cf. Brast, Break. 1. To break or rend by violence, as by an overcharge or by strain or pressure, especially. From within; to force open suddenly; as, to burst a cannon; to burst a blood vessel; to burst open the doors. "My breast I'll burst with straining of my courage." (Shak) 2. To break. "You will not pay for the glasses you have burst?" (Shak) "He burst his lance against the sand below." (Fairfax (Tasso)) 3. To produce as an effect of bursting; as, to burst a hole through the wall. Bursting charge. See Charge. Source: Websters Dictionary (01 Mar 1998) |

| burst forming unit | <haematology> A bone marrow stem cell lineage detected in culture by its mitotic response to erythropoietin and subsequent erythrocytic differentiation in about 12 mitotic cycles into erythrocytes. (18 Nov 1997) |
| burst size | The number of phages produced by an infected cell. (05 Mar 2000) |
| respiratory burst | <biochemistry> Response of phagocytes to particles (particularly if opsonise d) and to agonists such as formyl peptides and phorbol esters, an enhanced uptake of oxygen leads to the production, by an NADH dependent system, of hydrogen peroxide, superoxide anions and hydroxyl radicals, all of which play a part in bactericidal activity. Defects in the metabolic burst, as in chronic granulomatous disease, predispose to infection particularly with catalase positive bacteria and are usually fatal in childhood. (27 Jun 1999) |

| spider-burst | Radiating dull red capillary lines on the skin of the leg, usually without any visible or palpable varicose veins, but nevertheless due to deep-seated venous dilation; sometimes referred to as skyrocket capillary ectasis. Origin: spiderweb + sunburst (05 Mar 2000) |
| atomic number | <chemistry> Symbol Z. The number of protons in the nucleus of an atom and also its characteristic atomic number. The atomic numbers of the known elements form a complete series from 1 (hydrogen) to 103 (lawrencium). (16 Dec 1997) |

| magnetic mach number | <physics> A dimensionless number equal to the ratio of the velocity of a fluid to the velocity of Alfven waves in that fluid. (13 Nov 1997) |
| mass number | The mass of the atom of a particular isotope relative to hydrogen-1 (or to 1/12 the mass of carbon-12), generally very close to the whole number represented by the sum of the protons and neutrons in the atomic nucleus of the isotope (indicated in the name or symbol of the isotope; e.g., oxygen-16, 16O); not to be confused with the atomic weight of an element, which may include a number of isotopes in natural proportion.
