False Start

Getting out of blocks quickly in a foot race is a difficult skill to learn, because it's counterintuitive and runs against every instinct.  You literally have to throw your arms apart in the pose of someone who's already at full speed.  This will unbalance you and force you to lunge forward or fall flat on your face.

If you spend any time at track meets with the same starter, you develop a certain sense of the timing on when the starting gun is going to go off.  For those of you who have never run in track, the cadence is for Runner to take you marks.  This is sign to get into your blocks.  Take your time, the next signal won't come until everyone is situated and motionless, and some runners deliberately slow-roll this to discomfit the others. Then the "get set!' command comes, and everyone raises in the blocks to prepare to run.  Seconds later the gun fires, and this where the sense of timing can pay dividends.

I was running at a track meet at Ridgefield.  I was in the second heat in the 220, and had drawn the inside lane, which meant I was in the back of the pack.  The starting lanes are staggered to account for the turn, and the inside guy is a good thirty yards from the starting gun, at least.  That's far enough that a sound delay can seriously affect your start.  The guy right beside the gun will be in motion before you even hear it.  We're told to watch for the smoke, not wait for the gun, but when you're on your toes in blocks, you can hardly raise your head to see the gun.

Right beside me was one of the referees, also with a starting pistol, to watch for false starts.  I knew this guy by sight, he'd been a substitute teacher a couple of times at our school, but I didn't know him well.  I knew what happened in a false start, though.  You heard the starting gun, and almost immediately after a second shot that ended the race.  Everyone returns to their places, and whoever false started is removed.

"On your marks!"  I shuffled into the blocks, wiggled around and got comfortable.

"Get set!"  Up on my toes.  Shit, I can't see the gun, all I see are butts in the air. But I was used to this starter, I knew his timing. Wait for it, a one and a two and there we. . . .

My timing was off.  I flinched into a start, my hands literally came off the track as I started to launch myself.  But, dammit, the gun didn't go off!  So I check myself.  I swear, my feet never moved.  As I was on the down stroke from that, the gun went off.  I was delayed for an instant as the downward momentum on my arms was absorbed and I could launch myself.  I must have lost a half a second there.  I launched out of the blocks, fully expecting to hear a second gun in my ear.  Nothing happened. 

I won the race, and qualified for the district meet.

It was a week or two later, again at Ridgefield for the district meet. Earlier I had seen the referee who had been right beside me in the previous race, and smiled and nodded a greeting to him. I was near the start with my coach, jumping up and down, getting ready for the race, when he walked up to me.  He came pretty close, and said quietly, "You false started last time.  Don't let it happen again!"

I just said, "Yes sir!" What else can you say?  Helluva guy though.

Physics

I loved physics in college.  It was a subject I could sink my teeth into, it describes the universe in rational terms.  It's reproducible. My introduction to Physics was physics 201, calculus based physics.  16 week course instead of the 12 normally offered, 4 credits and a lab credit.  It came with massive, expensive, comprehensive text book that I have to this day.  I loved it.

I was teeing up to take the second part of this to fulfill the degree requirement for two science classes, when the US government, in a cost saving measure, announced that they were moving my separation up by three months.  Suddenly I was behind the 8-ball.  My carefully laid plans of how to finish my degree requirements before I separated went out the window, and I was scrambling to finish on time.  I had to give up the Physics II course and settle for the 12 week 102 course, what we affectionately referred to as "Dumbshit physics."  The textbook was about a quarter the size of the one I had.  In the first class the British instructor announced that we would be graded on our mid-term and final only.  Well, shit, I won't need the textbook then, will I?  No homework!

I was also taking some ECI video courses through the university of Chicago to bang out some easy credit for history, as well as another regular class that doesn't come to mind. As well as working midnight to 7am. I showed up for about half the Physics class, and slept through some of those.  It was mostly administrative people and non-technical types, Law enforcement, etc, looking to fill their science requirement.  One night as class was letting out and I was waking up in the back row, the instructor came over and asked, "Mr. Emerson, you're not asking many questions.  How do you think you're doing?"

I was wiping sleep from my eyes, and looked up at him and said, "Shit, I could teach this stuff!"  I probably could.  I was just here for the credit.

Mid-term time was coming up, and I figured it might be a good time to take a few hours and crack a book and bone up a bit.  then the whiners and admin rangers, the guys who had been head scratching their way through the class, started pestering the teacher to make it open book.  After much wailing and crying, the prof relented and declared that it would be open book, open note.  Well, hell, why even study? 

I arrived at the mid-term and he announced, "All right, clear your desks of everything but scratch paper and a pen." WHAT??!!  What about the open book, open note?  "Yes, that's what I agreed. You may use my notes.  and he handed us a sheet of paper filled with formulae.  No explanations, and worse, no units of measure.

I was clueless, and the "notes" were no help at all.  I had a very solid foundation in my previous physics class, so I spent the next three hours re-inventing physics from the ground up. 

The next week he was handing out the results, and announcing the grades as he did so.  C, B, D, C. . . and then he got to mine. "Mr Emerson.  That was a rather creative solution you gave for the pressure-volume question."

"Did I get it right?" I asked hopefully.

"Yes, unfortunately," he said dryly, "A+"
