  GREAT, FINE AND NICE THINGS DECLARED OBSOLETE


A personal selection of subjects of general interest and of subjects in the areas of mathematics and physics education that were declared obsolete by The Powers That Be (*)  





 

(*) The Powers That Be:: the infinitive "be" in this expression comes among all possible and meaningful interpretations of the infinitive tense closest to the Greek aorist tense .By the way, the Greek language has an Infinitivus Aoristi.
Indeed: The Powers That Be did exist in the past, do exist nowadays and will continue to exist as long as mankind will exist. So this infinitive carries very much the meaning of indeterminacy.
