Parallax
Greek for alternation, often used to denote subscreen systems in video games
used to enhance the feeling of depth and movement (a division of fore-,
middle-, and back-ground graphic fields scrolling at different rates), thus
contributing to
EHSPF
functionality. A prime
example being the

title. Parallax also
applies to the derivation of various stellar distances via techniques like
triangulation and the measurement of
Doppler
redshift. Results from these
measurements are given in units called parsecs, where
d=1/p
when the parallax is given in
arcseconds. However, this approach has proven
insufficient when applied to Venus'
black drop effect. Astrophysicists have
speculated this shortcoming is due to the infamous "parallax" error, a
mathematical glitch requiring an equational addendum [see below] to compensate
for what is essentially a rounding error when dealing with distances of
stellar magnitude.

1 A title later re-skinned as Punch-Out!!! Featuring Mr. Dream. It was widely and errantly reported the re-skinning was due to Tyson's 1992 conviction of raping Miss Black Rhode Island in an Indianapolis hotel room - however Nintendo cancelled Tyson's contract immediately following his stunning upset to Buster Douglas under the Tokyo Dome in 1990.
