No pencils use “lead”. It’s just called lead because the original material used looks similar to lead ore.

The words we use are funny.

I had a conversation with my wife yesterday explaining to her that "gas" (gasoline) wasn't a gas. (it can become one, but that's not where the name comes from)

Well, but in this case they're just homonyms, like how the word "bank" can refer to the edge of a river or a financial institution. The gas in your car is short for "gasoline"; you wouldn't call oxygen a type of gasoline, it's a gas.

And if you push the gas pedal, it does not mean more gasoline comes in, but more air (which then makes more gasoline comes in).

And people fear, that soon too many of the undividable atoms will be divided.
