um, can we borrow a can of beer?

maether decompreththing aether createth light waveth, and

on the wayside,
one should preliminarily determine what a "beam" is,
that is split by the beamsplitter; people,
who habitually think of a particle, when use
of the word, quantum, is made for the click
of a geigercounter (well, those might be ions) or what ever.

that is, a laser beam is just a very special case,
a highly modified or shaped set of waves, or
a standing wave of some sort, frequency, polarity
of lightwaves ... not Newton's clacking balls!

can a photon be only one cycle of light?

thusNso:
hey; maybe they'd let you look at your trophy
with your old 3d glasses!

thusNso:
dood, my valu of pi is lots simpler to calculate
than yours -- seven cans of beer & a string!

thusNso:
nice cartoon; is there only one beamsplitter in Sagnac?

--Pi, the surfer's canonical value, is not constructible
with a pair of compasses .. but, could be with a pair and
a half of compasses; dyscuss.
