** Superscalar architecture — The Pentium has two datapaths ( pipelines ) that allow it to complete two instructions per clock cycle in many cases.

** The microcode can employ both pipelines to enable auto-repeating instructions such as rep movsw perform one iteration every clock cycle, while the 80486 needed three clocks per iteration ( and the earliest x86-chips significantly more than the 486 ).

** the former yat is pronounced " e " in all positions.

** the former yat alternates between " ya " and " e ": it is pronounced " ya " if it is under stress and the next syllable does not contain a front vowel ( e or i ) – e. g. мляко ( mlyàko ), хляб ( hlyab ), and " e " otherwise – e. g. млекар ( mlekàr ) – milkman, хлебар ( hlebàr ) – baker.

** The breech refers to the mass of solid metal behind the bottom of the bore extending to the base of the breech and including the base ring ; it also generally refers to the end of the cannon opposite the muzzle, i. e., the location where the explosion of the gunpowder begins as opposed to the opening through which the pressurized gas escapes.

** Dean Cain in the 1990s series Lois & Clark: The New Adventures of Superman showed Clark as a normal and shy everyman demonstrating occasional touches of clumsiness ( e. g., pretending to burn his mouth on coffee ), but still a highly skilled journalist, much like the current post-Crisis portrayal.

** Social Security number, no dashes or spaces, followed immediately by branch ( i. e., 123456789USCG )

** Brownian dynamics, the occurrence of Langevin dynamics in the motion of particles in solution ( e. g. a grain in water, as was first seen by Brown ); its famous property is: MSD ~ t, where MSD is the mean squared displacement, and t is the time the process is seen
