You'd get even more disparate results if you polled people on who used (a) Facebook and (b) the photoelectric effect, despite every computing device with a display that renders Facebook being driven by the photoelectric effect.

"The Internet" is taken for granted and is so down in the weeds for most people that they don't realize they're using it. Similarly, every time that I glance at my watch to check the time, I'm not thinking about how it's using general relativity to calculate the time from its GPS sources, but it is.
