### Outside!

So there I was, waiting for my name to be called. She came out of the small room, reading off several names from a list. Not yet. I looked around the room, nervous people, some chatting some staring blankly off into space. Some studying the backs of their fingernails with feigned interest.

Twenty minutes passed. She came out again, read off another handful of names, then she looked at me, and nodded. It was time.

Sometimes, when I was a kid, I would ride my bike down to the beach to go body surfing. During the summer, the weather was hot, and the water was warm, so I enjoyed it just as much when there weren’t any waves as when there were. Sometimes I just enjoyed floating, letting the slow in and out of the tide move my body about. Every once in a while I would hear somebody say “outside set,” which meant that not the current set of waves, but the next one coming looked to be pretty decent.

Of course, a decent wave to a fourth grader on summer vacation means something completely different than what you may think of as a decent set of waves.

There is an interesting phenomenon regarding wave interference patterns when studying light. There is a famous double slit experiment, where they take a piece of material, and then put two small slits in a certain distance apart. Then they shine some light through on the other side of the slit, and measure the interference pattern on the other side with a special photographic plate. Because light travels in waves (sometimes) when it shows up on the other side, there will be peaks and troughs. The peaks are where the crests of waves coming through slot A line up with the peaks coming through from slot B. The troughs are where the lowest points from A overlap with B. The blank spaces in between are when a peak coming through slot A meets up with a trough from slot B, and they cancel each other out.

You can see this for yourself, by holding up your forefinger and thumb. If you hold you forefinger and thumb as close to your eye as possible, and then look through the space between them at a light source, as you bring your two fingers together, you can see the interference pattern start to form just before your fingers touch. You’ll see a small, but distinct pattern of darker and lighter “lines” between your fingers.

They say that physics is only makes sense because we see it over and over again, on a regular basis. Those that study quantum physics, or particle physics, knows that it follows a set of rules that is completely different than the rules we are used to in the macro world.

Not exactly.

There is the thing called the “correspondence principle,” and basically says that the laws of physics are the same for huge bodies, like planets, people, and trucks, as they are for tiny bodies like neutrons and photons, it’s just that the laws are specific to the condition.

Like the speed limit on the highway is 75 miles per hour, but through the small town is 35 miles per hour. They both still fall under the same speed limit law, but the law specifies different behaviors based on the environment.

But when I bought a boogie board, everything changed. Instead of swimming furiously to get to a wave that would only carry my poor body surfing skills so far, I could paddle out a lot quicker, and ride a lot longer. Simply by adding a simple tool to my pastime, I was able to get much more enjoyment, with much less effort. The only thing that became difficult was getting out through the waves as they were coming in. Before, as only a body surfer, I could simply duck under the wave and wait for it to pass over me. But with my boogie board, it became difficult. Many times I would paddle directly at the oncoming wave, only to get knocked back further than where I originally started.

Before, when I was body surfing, and I looked out at the waves coming in, and I wanted to get to a spot out beyond them, I didn’t give the waves a second thought. I just ducked under the water and let them pass over me.

But with my new toy, that made surfing a lot more fun, sometimes it was a hassle. How what used to be nothing more than some simple waves became a complex issue of timing. I had to wait until the waves were just right before I had a chance to paddle out beyond them, and wait until the new set came in.

Until my friend told me the secret. Get this thing called a leash, and attach one end to the boogie board, and the other end to your wrist. Then you could duck under the waves like before, you just had to sometimes fling your board up in the air before you did so.

Kind of like a tool added to a tool to make the tool more useful. With that added skill, boogie boarding was a breeze. And instead of floating just by myself, I could sometimes even pull myself up, lay on my back and stare up at the blue sky as the waves tossed me about.

When she finally called my name, I was about to fall asleep. I went into the small room, and I was surprised to see that it was just like the big room, only smaller. They had magazines, a couple of tables, and one of those bottled water fountains.

Then I had to wait there for another twenty minutes or so, but that is another story.
