Scientists who study clouds and water droplet formation help us
understand why rain never pours from the clouds in a stream but
falls in drops.
Clouds are simply very small particles of water. They stay
suspended because the force of gravity pulling them down is less
than the resistance of the air through which the raindrop has to
move.
Raindrops start when water condenses on a tiny dust
particle. These invisible droplets soon attract enough extra
water to form a visible drop. The smallest drops we call
drizzle. They hardly seem to fall at all - travelling only at
about one kilometre an hour. In comparison, during a tropical
downpour, raindrops can get as large as six millimetres. They
can fall at about thirty kilometres an hour, before breaking up
again into smaller drops because of air resistance.
There are several forces at work when raindrops develop. A
force called surface tension causes water to stick together and form
little balls. When the balls are big enough, gravity pulls
them down as raindrops. As they fall, the raindrops gradually
grow by colliding with other water drops. As they grow, they
accelerate under the influence of gravity. But frictional and
aerodynamic forces are also at work on the drops to limit their
size.
So next time you're caught in a storm, be thankful that the
balance of forces favours drops rather than streams when rain falls
from the sky.
MOVING BEYOND MATTER
by Ron Hughes
Even raindrops are subject to scientific laws, preventing them from
forming drops too large, or worse yet, falling in a solid
mass. If they were not subject to these laws, the weather
would cause a lot more damage to the environment than it does.
And if raindrops need to be governed and controlled, how much
more do we need the same? To be without law would lead the
whole human race into chaos. True, there are demagogues,
despots, and dictators who abuse their power, subjecting their
people to untold horrors in the name of law. But think what
chaos would reign if there were no laws at all. I mean,
none. No traffic lights to hold us up at an intersection, no
traffic police to deter us from speeding, no laws to prevent
employers from abusing their workers. You can make your own
list, but you get the point. Excessive or unjust laws can be
oppressive, but no laws at all - well that leads to disaster.
It's true that law applied wrongly can bring us into
bondage. Yet the answer is not to do away with law, but to
bring other laws into play that will modify the effect those laws
have on us.
Let me explain: - We are all acquainted with the law of
gravity. We cannot live without it, but there are times it can
be very restricting, particularly when we wish to fly. Before
the Wright brothers came along, human flight was only a dream.
Now we know there are other laws in the universe that can overcome
the law of gravity, namely, the laws of aero-dynamics. By
applying those laws we can, for a time, be free from the restricting
effects of gravity.
Well. something similar is true for us in the spiritual
realm. We cannot banish law entirely from our lives. If
we do, we will court disaster. But we can apply other laws
that can free us from the bondage of law. I am thinking particularly
of the law of forgiveness. God extends mercy and forgiveness
to all who will trust Him. Applying these laws, we can fly
into the atmosphere of God's love.
