I'm thankful for vibration

I'm thankful for vibration. Why?

Here's why. Vibration makes it possible for waves to exist. Something vibrates up and down, or back and forth, or around and round, and a wave is created. So who cares?

Waves are really important. If you live near the ocean, or any other large body of water, waves can kill you, or help transport you, or bring things to you, or give you occasion for recreation. That's one sort of wave, and it is, I believe not nearly as important as some other kinds of waves.

The most important kind of wave is electromagnetic. I have posted on this type of wave in the past, and tried to indicate why I (and you) should be grateful for its existence. Let me just indicate some reasons why I'm thankful for electromagnetic waves, in brief. Without them, there would be no light, and we couldn't see. Our appreciation of beauty would be much diminished. Without them, I wouldn't be able to listen to a radio, or watch television, or connect, through our wireless router, to the Internet, or through our cell phone, to other people. Without them the sun's energy would not reach the earth, and power photosynthesis, the water cycle, and keep us from freezing solid.

Another kind of wave is sound waves. (Many of the principles that apply to electromagnetic waves also apply to sound and other mechanical waves, but there are significant differences.) Without sound, I couldn't hear voices or music or various kinds of signals and warnings. I love to hear music and other sounds. God must, too. In Job 38:4-7, Job is told that, at the creation of the earth, heavenly beings shouted and sung! In Revelation 5:6-14, we are told that, when Christ is honored in heaven, heavenly beings, and humans, will shout and sing! (I recognize that it is possible, perhaps even likely, that neither of these passages are meant to be taken absolutely literally. But they mean something. I believe that God likes sound, including music. After all, He designed the universe so that mechanical waves would make them possible.

I have posted about other things I am thankful for, probably including vibrations, at other times. See here and here for links to these posts.

I'm also grateful for readers like you. Thanks!
