I have seen so many grimaced faces when "physics"
is mentioned, that at some point I started believing I had actually majored in
the subject and hated it, too. So when I
signed up for a Physics class this week, I mistakenly thought I was taking a
refresher.
I was eight when my first real physics lesson
happened at the fat end of a Wiffle Ball bat. Wiffle balls were the brainchild of
parents who'd had enough of the
broken windows caused by regular baseballs, so they invented something that
could only break their cheap stuff. The oddly
shaped plastic bat that sent the Wiffle ball flying would also - if swung just so against a car hood - have enough
momentum to hit the person swinging it between the eyes. Twice.
I've heard.
That is precisely
the moment a smart person should appear to inform all onlookers that they're witnessing
physics in action! And the way their
bodies convulse with laughter? More
physics!
The only real physicist I've ever known is my friend
David. He's so smart it's scary, but
he's real nice and never makes me feel dumb.
He'll tell me just enough about the Universe so that my eyes don't dry completely out, but I'm guaranteed to
have much more pleasant dreams than my usual Gilligan's Island nightmares.
David worked on some kind of refrigeration unit that was
sent into outer space for testing.
Or something.
I was surprised by all the information in this week's
Physics Class. (Not Wiffle-Ball-Bat
surprised, but still - pretty surprised.)
I'd stashed a few Keep Awake distractions in my backpack just in case,
but everything - including the HoHos - were still in their wrappers when I left
for home.
I learned that Einstein was an island unto himself, meaning
he used very few citations in his work.
I did not learn what 'citation' meant back then, but I'm thinking he did
not loiter or violate speed limits.
Maxwell, a mathematician from Scotland, developed the concept
of 'fields' to unite electrical theories, but all I remember is that his middle
name sounds like "Clark" and is spelled "Clerk."
A guy named Michaelson trained at Annapolis before measuring
the speed of candlelight moving in different directions. A German guy named Planck (pronounced
"Plonk" - what is it with scientists?) was interested in the theory
of heat, so he went ahead and put the Quantum
in Quantum Physics.
I do not even understand how my toaster works.
But the most interesting story, about a guy named Newton,
was also the most familiar. My mind went
immediately to that shot of him relaxing under a tree, eating an illegal apple
- no, wait - that was Adam and Eve - this guy was reading a book and got hit by
a gravitational apple. Big difference.
I think the apple part is what confused me for years,
obscuring the fact that Newton was not around at the beginning of time. I should have put that two-plus-two together from the wrinkled blousy shirt he wore over
those brown pants that were tucked into his big-buckled boots.
Adam and Eve wore plants.
Newton survived his awkward teenage years, but was only 22 when a Big Plague hit England.
He couldn't go outside - and Nintendo was a few years off - so he invented
calculus. Then he riffed off everybody
else's stuff, explaining Copernicus's theory about planets revolving around the
sun and Keppler's theory of elliptical orbit.
Then he went ahead
and developed the theory of "force" after rearranging furniture for
the hundredth time and writing letters to every budding microbiologist pal trapped
in their homes working on ways to help fellow earthlings survive the plague.
Those guys knew how to handle boredom.
I have developed a theory about why today's 22-year-olds play
Grand Theft Auto instead of inventing
more science: If those kids from the past had
just slowed down a little - we would
still have stuff to invent. They were so
intent on figuring out the exact distance to the moon that today's youngsters
don't have a reason to wonder about anything.
Oh, wait. How to explain
my friend David? All theories discussed
in today's class had been floated and validated and big trophies had already
been awarded at whatever kinds of dinner parties they had in the 1500s - but
David still wonders about lots of things.
A few years ago he explained (in my language) Einstein's
Theory of Relativity. Apparently, there
is an unsolved mystery there and I said I'd go ahead and figure it out in my
spare time. This made David laugh, but I
got the distinct feeling he believed on some level that I could do it.
I learned in class about a gentleman named Hippolyte Fizeau
(incredibly, pronounced as spelled) who hauled mirrors up a giant mountain to
measure the speed of light. Thanks to
Mr. Fizeau, I know that the light I see from a star is the same light I'd see
if I ever got close enough to hold hands with it. But like so many other messages, it gets a
little diluted on its way to me.
I'm still working
on the Einstein thing, but my research is easily bogged down by distractions I'm blaming on every scientist who came before me. I drive
my automatic car home after work,
take dinner from the freezer, heat it in the microwave, find a
ballgame on television, use my cell phone to check for emails, then write a little on my laptop before turning out the lights and hopping into bed. Thanks a lot, guys with funny names!
Same sun.
Same moon.
Same 24 hours for solving questions that arise in the time
we stop to sit and think. If a giant technological
virus causes the next Big Plague, what would we choose to invent again?
Maybe we'd reinvent
communication. That's where all the
practice I've given my friend David will really pay off.
He can start us back on the right path by instructing his
physicist friends in a class called "How to Explain Anything to Anybody."
(Want that wind-blown
look without the flashy-convertible expense? Um, no. No, you don't. I've got real-life motorcycle information for you here next Friday.)
