This
legend, the truth of which is not necessarily related to its value,
concerns a question in a physics degree exam at the University of
Copenhagen: "Describe how to determine the height of a skyscraper with a
barometer."
One student replied: "Tie a long piece of string to the neck of the
barometer, then lower the barometer from the roof of the skyscraper to the
ground. The length of the string plus the length of the barometer
will equal the height of the building."
This highly original answer so incensed the examiner that the student was
failed immediately.
He appealed on the grounds that his answer was indisputably correct, and
the university appointed an
independent arbiter to decide the case. The arbiter judged that the
answer was indeed correct, but did not display any noticeable knowledge of
physics.
To resolve the problem it was decided to call the student in and allow him
six minutes in which to provide a verbal answer which showed at least a
minimal familiarity with the basic principles of physics.
For five minutes the student sat in silence, forehead creased in thought.
The arbiter reminded him that time was running out, to which the student
replied that he had several extremely relevant answers, but couldn't make
up his mind which to use.
On being advised to hurry up the student replied as follows:
"Firstly, you could take the barometer up to the roof of the skyscraper,
drop it over the edge, and measure the time it takes to reach the ground.
The height of the building can then be worked out from the formula H =
0.5g x t squared. But bad luck on the barometer.
"Or if the sun is shining you could measure the height of the barometer,
then set it on end and measure the length of its shadow. Then you
measure the length of the skyscraper's shadow, and thereafter it is simple
matter of proportional arithmetic to work out the height of the
skyscraper.
"But if you wanted to be highly scientific about it, you could tie a short
piece of string to the barometer and swing it like a pendulum, first at
ground level and then on the roof of the skyscraper. The height is
worked out by the difference in the gravitational restoring force T = 2 pi
sq root(l / g).
"Or if the skyscraper has an outside emergency staircase, it would be
easier to walk up it and mark off the height of the skyscraper in
barometer lengths, then add them up.
"If you merely wanted to be boring and orthodox about it, of course, you
could use the barometer to measure the air pressure on the roof of the
skyscraper and on the ground, and convert the difference in millibars into
feet to give the height of the building.
"But since we are constantly being exhorted to exercise independence of
mind and apply scientific methods, undoubtedly the best way would be to
knock on the janitor's door and say to him 'If you would like a nice new
barometer, I will give you this one if you tell me the height of this
building'."
The student was Niels Bohr, the only Dane to win the Nobel prize for
Physics.
Just goes to show that there are lots of different ways to measure the
height of a building. But suppose you wanted to measure
something a little more abstract -- your Christianity, for example.
How would you go about doing that?
Some folks simply look around at everyone else and see how their lives
compare. "Well, I'm not as immoral as most of the people I know."
"I'm certainly better than the hypocrites that go to church down there."
Paul said, though,
"For we dare not
class ourselves
or compare ourselves
with those who commend themselves.
But they, measuring themselves by themselves,
and comparing themselves among themselves,
are not wise."
(2 Cor. 10:12).
They're not wise because we
have to measure ourselves using a higher standard. The standard we must
use is nothing less than the life of Jesus Christ.
"....till we all come to the unity
of the faith
and of the knowledge of the Son of God,
to a perfect man,
to the measure of the stature
of the fullness of Christ."
(Eph. 4:11-13).
Using God's Word as our guide,
we all see just how far we have yet to grow.
I encourage you to take measure of your life today
as you strive to grow in Christ.

In Jesus'
name, Amen.
