The Big Bang, by Ricky


In 1966 I was a senior at South Tahoe High School (now the Middle School). One of my classes was Ecology and was team taught by Mr. Harold Mapes and Mr. Al Hildinger.  Mr. Hildinger also taught a lapidary class during the evening adult education program.

Our ecology class was taught in the biology classroom of the science wing of our school.  At the time, the school was laid out like a giant letter “E” with the science wing at the top “arm” of the “E”.  The administrative offices and library were located along the main corridor representing the upright line of the “E” with other classrooms off the other arms of the “E” shape.  The science wing had five classrooms with the biology/ecology classroom at the beginning of the hallway followed by the chemistry classroom, two more classrooms, and at the end of the hall was the physics room.

On one particular spring day near the end of term with graduation rapidly approaching, Mr. Hildinger was teaching our ecology class, as previously indicated, in the biology room.  He was teaching the adult lapidary class in that same room later in the evening and wanted to have his rock-saw moved from the physics classroom at the end of the hall to the biology room and asked for a volunteer to go get it for him.  No one volunteered.  After waiting a few seconds, he told me, “Please go get it.”  I said, “I don't want to.  I'll probably break it.” (I was not having a good day.)  Handing me the key to the room, he said, “Just go get it.”  I left the room to do so.

Upon arriving at the physics room, I used the key to gain entry and immediately saw the rock-saw several feet in front of me.  It was basically an electric motor looking to weigh in at about 30 pounds, attached to a mechanism to hold a rock sample while a diamond tipped circular-saw blade would spin while slowly moving forward and slicing its way through a rock sample.  The result would be a thin slice of rock to be turned into jewelry or other item of display.

The rock-saw was sitting in a large 5 inch deep tray located on the top of a metal cart about 5 feet tall, 20 inches wide, and 3 to 3 ½ feet long.  The cart was supported by 4 spindly metal legs on small wheels with two metal platforms located at the bottom and middle of the cart’s legs to provide stability for the legs and thus the cart itself.  Along with the rock-saw in the 5 inch deep tray at the top of the cart was approximately 3 gallons of kerosene used to cool the saw blade and lubricate the rock sample while it was being cut.

The whole contraption was heavy and did not want to roll very well so I had to push hard to get it moving.  Fortunately, the cart was aligned with its long axis towards the door so I was able to push and pull it out the door into the hallway after draping the power cord up along the rock-saw.  It was not easy to get it out the door because the wheels would not pivot.  I locked the room and prepared to complete the task.

Since I could not get the wheels to pivot, I decided to push the rectangular cart sideways down the hall.  I began by placing my hands on the top tray and gently pushing.  Nothing happened.  I pushed harder.  Still no movement.  I pushed even harder.  Finally, the cart began to move towards the biology room some little distance away.  I passed one classroom.  I passed the second classroom.  I was nearly at the chemistry room door when Murphy's Law teamed up with the laws of physics and gravity.

As I neared the chemistry room door, I failed to notice that the power cord had fallen off the rock-saw down to the floor.  It landed in front of one of the little wheels.  When the wheel made contact with the power cord it stopped turning and the leg it was attached to stopped moving forward causing all the legs to stop moving forward.  However, I was still pushing on the top of the cart which did not stop moving forward.  By the time I noticed, the top of the cart was leaning away from me not very far but beyond the center of gravity and inertia was in control.  I could not hold it and pull it back to upright.

Time slowed down as I watched in horror as the momentum kept the rock-saw and cart top moving to the inevitable conclusion.  In less than three heart beats it hit the floor with a resounding BANG which echoed down the halls, around the corner, and alerted most of the administrative personnel, librarians, and all the classes in the science wing that the chemistry lab had exploded.  Instantly, it seemed, all the students in the science wing classrooms began to empty out into the hall and I was caught like a deer in headlights.  As bad as this was, 3 gallons of kerosene were now flowing down the hall towards the chemistry room.  The floor having been depressed by many years of students walking into the room, the kerosene made a 90-degree right turn and began to flow into the chemistry room.  I could envision a real explosion if kerosene fumes reached a Bunsen burner.

When the mess was finally cleaned up and I helped Mr. Hildinger lift the cart upright and moved it into the biology room, he determined that the rock-saw was okay but the diamond saw blade had been warped by the force of the fall.  It cost him $100 to replace but he never asked me to help out.  This was my own personal experience with an Alexander's Terrible, Horrible, No Good, Very Bad Day!

About the Author 


I was born in June of 1948 in Los Angeles, living first in Lawndale and then in Redondo Beach.  Just prior to turning 8 years old in 1956, I was sent to live with my grandparents on their farm in Isanti County, Minnesota for two years during which time my parents divorced.

When united with my mother and stepfather two years later in 1958, I lived first at Emerald Bay and then at South Lake Tahoe, California, graduating from South Tahoe High School in 1966.  After three tours of duty with the Air Force, I moved to Denver, Colorado where I lived with my wife and four children until her passing away from complications of breast cancer four days after the 9-11-2001 terrorist attack.

I came out as a gay man in the summer of 2010.   I find writing these memories to be therapeutic.

Hmmm, Strange by Betsy


I have an in-law, a cousin, who, himself is not so strange, rather his world of knowledge and know-how seems strange to one who does not study physics. Bill, and his wife Marion, my cousin, are a couple of those spoon benders you may have heard about. Because of his knowledge and belief in the world of quantum physics, and, shall we say some sort of a heightened awareness, Bill and his associates are able to bend heavy spoons with their bare hands, no tools. They twist the handles into cork screw shape using nothing but 10 frail digits and the power of their minds.

Now, you may be saying, “Well, it’s some sort of trick, perhaps a visual trick.”

Trust me, it’s not a trick. Gill and I witnesses the feat with our own eyes.

My cousin gave us the spoon as a souvenir, or as a reminder of the power of the mind. The twisted spoon was carefully laid away amongst our most prized possessions, but somehow is not making its presence known when we most would like to put our hands on it. Perhaps we hid it too well or the magic continues and it has vaporized into a billion particles, but the tortured tool is not to be found in the house. Hmmm, strange.

Bill did the spoon bending as a demonstration of a concept of quantum physics. The fact that it works, perhaps is the result of synchronicity. The phenomenon is based on the theory of quantum mechanics which explains the synchronization of the vibrations of the particles that make up energy with matter. Now apparently, if you can synchronize these things, you too can be a spoon-bender. Hmmm, strange.

String theory is another subject on the agenda of these scientists. String theory has to do with particle theory. I do not speak the language of physics and do not have the concepts and therefore can neither understand nor attempt to communicate what any of it is about. Only that it has to do with the make-up of subatomic particles--the make-up of all matter. The recent discovery of the so-called God Particle has brought much of this to light recently. Even the popular explanations are mind-boggling, I find.

Subatomic particles leave me cold. I cannot see them bouncing around when I look at something and, therefore, am not terribly interested in them.

The theories of quantum physics are to an unsophisticated mind such as mine are, well, strange. Take for example the concept that time is not moving. According to some physicists the idea that the past is gone, the present is here now, and the future is yet to come is but an illusion to us earthly creatures. All of time, all that ever was and all that ever will be is actually present now.

We’ve all heard the advise given that we should live in the NOW, not worry about the future or live with regret for the past. The idea that the Now consists of the past and the future as well as the present moment in time, that the flow of time is an illusion, I find, presents problems when trying to apply this simple advise, live in the now.

All I can do is continue to try to live in my illusionary world and try to focus on what appears to me to be the NOW, hopefully learn from the past, and look forward to the future, but mind you, stay focused on the NOW-- and right at this particular NOW I can’t stop scratching my head when I think of my cousin and all those twisted spoons. Hmmm, strange.
