The glass is never empty

I ask a lot of questions.

Siri, how many molecules are in a cup of water?

I know I don’t have to say her name. But it just seems polite in the presence of a palm-sized supercomputer. She doesn’t take long to calculate my quandary.

The answer is about 7.91 times 10 to the 24th power molecules.

Then another thought strikes me.

Siri, how many molecules are in a cup of air?

I almost expected to stump her with that one. But my pocket-god comes through.

The answer is about 6.27 times 10 to the 21st power molecules.

She talks with an Australian accent. This makes her sound more other-worldly. Or perhaps it just makes her sound under-worldly. I’m not sure, but it keeps me entertained.

One pint glass can hold two cups of liquid. Therefore, if it is filled half-way with water, it contains one cup. That’s 7.9 septillion molecules. That leaves the other half full of air. That’s almost 6.3 sextillion more molecules. Even half empty, that glass contains (give or take):

7,906,300,000,000,000,000,000 molecules
