Rip Bob , you will be truly missed ! <| sep |> The current way of thinking about progress , from a scientific point of view , in my country ' s academia is that the word basically doesn ' t mean anything . Its a complicated topic that is hard for me to put it in english too much lingo , but the gist of it is that to think about previous knowledge as obsolete and current ones as correct is an horrendous anachronism . All of them were momentary and ephemeral stepping stones in the history of science , all of them necessary to expand human knowledge . It also ignores the fact that most of what we know its either very incomplete , or just flat out false . <| sep |> Grasshoppers . 1 oz clear creme de cacao 1 oz green creme de menthe 1 oz heavy cream .
