Beep…beep…beep…
Every day, I do a lot of things by radio. I send contact and appointment information from my computer to my telephone. I make telephone calls. I unlock the door at work. People don’t seem to think of these things as radio—the technologies have other names: Bluetooth, cellular, RFID, or just “wireless.”
I realized today that I like referring to such everyday actions as by radio because my mental picture of radio isn’t mundane. Radio is humming transformers, glowing tubes, and dials with needles flicking back and forth. Radio reaches out a hundred million miles, a whisper bearing pictures of Saturn. Radio is a colossal tower standing astride the North Pole, sending waves to reach the whole Earth.
It tickles me that I use essentially the same thing to open my garage door in the morning.
