From time to time, when people find out that it took me two Ph.D.s to work out what I wanted to be when I grew up, they'll make comments about what a pain it must have been wasting those four-plus years learning chemistry stuff that is well-nigh useless for a professional philosopher.
Let the record reflect that last weekend, I made use of a skill that I honed in my graduate chemistry training.
Sadly, that skill was bottle-washing -- not the most intellectually stimulating thing to do. But, when the bottles need washing, knowing how to wield a bottle-brush with authority is important.
And, now we have apple cider (or more properly, the yeast contained in that cider) munching on sucrose in the bottles, developing some carbonation. Plus, the carboy is now free and ready for this Fall's press, which is good, as the apple tree is groaning under the burden of all those apples.
