Any listing
of the most notable pedagogues from my past would have to include amongst its
upper ranks my high school Physics teacher.
And any listing of the most notable lessons he taught me would have to
include the lab and lecture on the latent heat of fusion. The lecture ended with an admonition that has
remained with me all these decades -- "Do Not Confuse Heat with
Temperature!"
There is one
particular member of our congregation with whom it has been amply shown that I
cannot work. I have nothing particular
against him, but he just does not think the same way I do. The kerfuffles we have gotten into have
included, but not been limited to, (A) why is it necessary for me to back into
parking spaces instead of going in head-first with my car; (B) why was it
necessary for me to take a phillips-head screwdriver and tighten the screws in
the shul refrigerator (the handles were coming loose, shmuck!); and why did I
have to park my bicycle in the back yard of the shul (did you want me to bring
it INTO the shul?). He sees no problem
with New York's firearm restriction laws, he doesn't understand how illegal
aliens are costing American taxpayers any money, and when Obamacare first was
legislated, he was incredulous that I and a few other individuals were saying
that it would actually increase the cost of healthcare.
In any event,
for those who have not noticed, there has been a significant amount of snow
deposited here on Long Island during the past week or so. T but today was supposed to be (and in fact
was) significantly warmer than the past few days. I took. the snow shovel and started throwing
snow and ice that was on the walkway up to the shul out onto the street, to
facilitate its disappearance. So this
fellow congregant whose mental processes (?) are incompatible with my own
started with me. "It's going to be
in the 40's today, so it will melt anyway!"
After
mentally marshalling the physics lectures regarding how the white snow reflects
the sun's rays and their concommitant heat, and how the snow evaporates into
the atmosphere with a liquid water stage that is brief if it happens at all, and
the latent heat that must be absorbed when water transitions from solid state
to liquid state, and how temperature and heat are not necessarily the same
thing, and how we need to get rid of the snow and ice, et cetera, I realized
that there can be no rational discussion with this man. So instead of reprising all of those
informative and valuable lectures from my high school physics course (and a few
from my college physics course -- my Physics 101 professor was no slouch
either), I just said to him, "This is what I am doing. If you don't like it, then report me to the
Rabbi!"
Meanwhile, even
before today, my own driveway was clearer than almost all of my neighbors'
driveways because I took pains to expose the bare black asphalt and let the sun
do its thing. The temperature may be low,
but there was plenty of sun for most of the day. We didn't have much in the way of
temperature, but the rays of the sun did deliver sufficient energy to dispatch
most of the ice and snow away.
Temperature and heat are not the same things.
