31 Days of Wonder

Vacation is about letting go, relaxing and recharging. That’s what this blog will be about for the month of August, and I hope you’ll join me.

There is beauty, wonder and inspiration everywhere. Tomorrow, I’ll lead off with videos of a couple of teenagers whose friendship changed one of them from social outcast to international star. We’ll see where the month takes us from there.

The Nyquist–Shannon Sampling Theorem

Nyquist-Shannon SamplingAt a Meetup group last week, one of the conversationalists mentioned the Nyquist-Shannon Sampling Theorem.

As applied to sound waves, this theorem states that if you want to know everything there is to know about a sound, you must measure (“sample”) it twice as frequently as the highest-frequency pitch it contains.

I immediately thought of the increasing rate of information-flow in our society. In the old days, knowledge came at us much more slowly. You didn’t have to take stock of it all that often.

These days, according to a study out of Berkeley, we produce about 5 exabytes of information every year. That’s the equivalent of 37,000 Libraries of Congress. Every year. And the deluge is only accelerating.

This is happening in every field, including whatever field is most prominent in your worldview.  If you want to have a clue, you must sample this information more frequently than ever.

Fifty years ago, a man would take a serious look at his beliefs maybe once in his life. It was called a midlife crisis — a one-time episode of questioning and irresponsibility. Now I think we can say that a midlife crisis is irresponsible because it’s only one-time! With 5 exabytes of information coming at us every year, we ought to be questioning continually.

We can’t spend every day in crisis, obviously, but at a minimum we can learn something every day, right?

Now that you know what the Nyquist-Shannon Sampling Theorem is, you have met today’s obligation. Congratulations! My wish for you is that tomorrow will bring more learning or, better yet, more questions.

Why I Became a Christian

“Wait, what!? I thought you weren’t a Christian!” That’s true now, but this post is about when I was a child of about 11, and what took place at  Camp Sandy Hill.

I don’t remember much exposure to the Christian faith before that summer. Our family had attended church when I was quite young, but for whatever reason we hadn’t attended regularly for several years.

I did think about God, but mostly in the negative. I recall that when we said the Pledge of Allegiance in elementary school, I was uncomfortable with the “under God” part. Sometimes I didn’t say it, and sometimes I said it but gave myself the excuse that God didn’t exist anyway so it didn’t matter.

I also recall an episode in first grade. This was in the 1960s, when prayers were still said in public school. After one prayer, one of my classmates told the teacher that I had had my eyes open. She was a wise lady and replied, “You wouldn’t have seen that his eyes were open if yours hadn’t been open, too.”

But I did have beliefs. My cornerstone belief was in Justice: I thought that good would eventually be rewarded and evil recompensed. Just how this happened I didn’t know, but it was almost like the Law of Conservation of Mass that I would later learn in high school. The universe would always be in balance.

That was my frame of mind when I went away to my first summer at camp. Sandy Hill was a Christian boys’ camp, with all that entails: fun crafts and activities, listening to Christian messages and singing Christian songs. One song was by far my favorite:

He’s Everything to Me
by Ralph Carmichael 

In the stars His handiwork I see;
On the wind He speaks with majesty.
Though He ruleth over land and sea,
What is that to me?

I will celebrate Nativity,
for it has a place in history.
Sure, He came to set His people free.
What is that to me?

Till by faith I met Him face to face
and I felt the wonder of his grace.
Then I knew that He was more
than just a God who didn’t care
That lived a way out there

And now He walks beside
Me day by day,
Ever watching o’er me lest I stray,
Helping me to find that narrow way
He’s Everything To Me.

Here’s a cheesy version sung around a campfire:

I had always wanted to do the right thing, so the idea that the majestic creator of the stars would be “ever watching over me lest I stray, helping me to find that narrow way” was very appealing. The evangelical Christian message that someone had to pay for our sins fit well with my idea of Justice. It made perfect sense to me that either I could pay (in hell) or I could accept Jesus’ payment on the cross and go to heaven instead.

So one night, lying on my bunk, I committed my life to Christ. I felt quite a rush. It was mind-blowing to have a connection — nay, a relationship — with he who “speaks on the wind” and “ruleth over land and sea.” Being even then a truth-seeking beagle, it also felt good to be right. It felt even better to be right with God.

Regular readers of the blog know that I look on faith differently now, but that was a very genuine experience of my 11-year-old self and I don’t want to tear it apart it in this post. I just wanted to tell that story, and now you have it.
