Did you know that Chopin didn't give any programmatic titles to his pieces? He always preferred to refer to them by opus and number; he thought that the idea of artificializing the music of a piece with a title was repulsive.
That's not to say, though, that programmatic titles can't reveal a lot

that eating before swimming is really not harmful at all. The common misconception is that one should not eat before swimming. The only harm in this is that you will feel uncomfortable but it is not hazardous to your health.

I hang out with a lot of math students at my university because we're in the same faculty, I can barely go a full hour without a math pun.
But, fun fact, there are just over π*10^7 seconds in a year.

There is approximately one mole mL of water in the Pacific ocean
Relative atomic mass of water = 14
mL = 1cm^3
Density of water is 1g/1cm^3
So there is 1g of water in 1mL
and 1/14 moles in that 1g
Using Avogadro's number 6.022 x 10^23
We can find the no. of atoms in that 1g of water
6.022 x 10^23 x 1/14 = approx. 4.30 x 10^22 atoms in 1g or 1mL of water.
