Just like sending an email

The last thing we discussed before she closed her eyes to go to bed tonight:

“Daddy, how does the remote control for the TV work?”

“Well… the remote has batteries in it, and when you press a button, it sends a signal through a tiny little light bulb at the front end of the remote control.”

“Oh yeah! I’ve seen that little light bulb thingy!”

“Yeah – so there’s a little sensor on the TV that receives the infra red signal from the remote control, and that signal tells the TV to change channels, turn on or off, or turn the volume up or down.”

“So it’s kind of just like sending an email, right? It just sends it!?”

“You’re five. How do you know this stuff?!”
