The language of science
Sometimes I lament being so old, when I realize how the very language changes, in ways I resist.
Like when "bad" meant bad, not good.
Or, when being "chivalrous" was a good and welcome and admirable thing.
Or when "scientific method" (largely the process of falsification) didn't mean "Why should I make the data available to you, when your aim is to try and find something wrong with it?"
Just don't understand the way these kids talk today.. !
