:baker's dozen: (p12)  A {loaf} {hassle}d by two {block}s and two
   {caterer}s.  The original form (using p4 and p6 oscillators to
   do the hassling) was found by Robert Wainwright in August 1989.

:barberpole:  Any p2 oscillator in the infinite sequence {bipole},
   {tripole}, {quadpole}, {pentapole}, {hexapole}, {heptapole} ...
   (It wasn't my idea to suddenly change from Latin to Greek.)
   This sequence of oscillators was found by the MIT group in 1970.
   The term is also used (usually in the form "barber pole") to
   describe other extensible sections of oscillators or spaceships,
   especially those (usually of period 2) in which all generations
   look alike except for a translation and/or rotation/reflection.

:B-heptomino: (stabilizes at time 148)  This is a very common
   pattern.  It often arises with the cell at top left shifted one
   space to the left, which does not affect the subsequent evolution.
   B-heptominoes acquired particular importance in 1996 due
   to Dave Buckingham's work on {B track}s - see in particular
   {My Experience with B-heptominos in Oscillators}.

:blinker ship:  A {growing spaceship} in which the wick consists of
   a line of {blinker}s.  An example by Paul Schick based on his
   {Schick engine} is shown below.  Here the front part is p12 and
   moves at c/2, while the back part is p26 and moves at 6c/13.  Every
   156 generations 13 blinkers are created and 12 are destroyed, so the
   wick becomes one blinker longer.

   repeatedly push a block further away.  The following pattern,
   in which three gliders push a block one cell diagonally, is an
   example of how this can work.

:blonk:  A {block} or a {blinker}.  This term is mainly used in the
   context of {sparse Life} and was coined by Rich Schroeppel in
   September 1992.

:boat-bit:  A binary digit represented by the presence of a
   {boat} next to a {snake} (or other suitable object, such as
   an {aircraft carrier}).  The bit can be toggled by a {glider}
   travelling along a certain path.  A correctly timed glider on a
   crossing path can detect whether the transition was from 1 to 0
   (in which case the crossing glider is deleted) or from 0 to 1 (in
   which case it passes unharmed).  Three gliders therefore suffice for
   a non-destructive read.  The mechanisms involved are shown in the
   diagram below.  Here the bit is shown in state 0.  It is about to be
   set to 1 and the switched back to 0 again.  The first crossing glider
   will survive, but the second will be destroyed.  (In January 1997
   David Bell found a method of reading the bit while setting it to 0.
   A {MWSS} is fired at the boat-bit.  If it is already 0 then the
   MWSS passes unharmed, but if it is 1 then the boat and the MWSS are
   destroyed and, with the help of an {eater1}, converted into a glider
   which travels back along exactly the same path that is used by the
   gliders that toggle the boat-bit.)
