I would put “radio” a little higher on this list. A new survey commissioned by Thomas & Friends ranked the 20 most important inventions of all time. And radio just missed the Top 10 at #11. Here are the top ten inventions in order:
1. Electricity. Or technically, harnessing electricity.
2. The telephone.
4. The lightbulb.
5. The Internet.
Radio is 11th. Here’s the rest of the Top 20 that ranked lower: Steam-engine trains . . . cameras . . . the printing press . . . clocks . . . optical lenses . . . the compass . . . boats . . . helicopters . . . and tractors. (SWNS)
