What we also learned observationally before and after
deflecting the peas
experimentally was that gravity went to work on the
peas as soon as they left the tube, and
that as the peas were decelerated by air resistance
below the rate of acceleration that
rendered them approximately immune to the pull of gravity,
that latter force became ever
more effective as the air resistance took its toll of
energy from the peas, and the peas were
deflected progressively Earthward. We also observed
that no wind was blowing, and when
we did not deflect the peas with our finger, they all
followed a progressively descending
path in exactly the same plane until they hit the ground.
Next we learned that if we
intruded our finger horizontally a discrete distance
into the tubular space-path of the peas,
they were deflected at some discrete angle (less than
90 degrees, diametrically away from
the point of entry of our finger into the peas' tubular
space-path), and that if we did not
move our finger further into the tubular space-path,
each traveling pea thus interfered with
deflected the same angular amount horizontally away
from our intruding finger and held
that newly angled direction, yielding further only to
air resistance and gravity, with the
result that each successive pea thus discretely deflected
proceeded in a progressively
curved trajectory, but always within the same vertical
plane. In other words, successively
separate and discretely distanced progressive intrusions
of our finger into the tubular
space-path of travel deflected the vertical plane of
the trajectory of the peas into a new but
again sustained vertical plane of travel, that new vertical
plane occurring each time at a
more abrupt angle from the original nonintruded vertical
plane of the stream of traveling
peas. Thus we learned that we could deliberately aim
the peas to hit targets within the
range of such traveling. (We have all succeeded in deflecting
the trajectory of a pressured
stream of water in just such a manner, but we cannot
see the individual molecules of water
thus deflected and think of it as a continuous stream.)
The discretely modified behavior of
our pea-shooter's individual peas and the individual
steel-ball "hammers" of the Olympic
hammer-thrower altogether permit our comprehension of
the parts played by individual,
but invisible-to-human-eyes energy quanta in bringing
about only superficially witnessed
motion phenomena that most often appear deceivingly
as motionless solids or as swiftly
rotating solid flywheels such as those of gyroscopes.
