New article: The secret of the Aleph - Karl-Ludwig Butte - 07-22-2017 03:59 PM
Did you ever wonder what’s the use of set theory ? Do you remember those long gone schooldays when your mathematics teacher bullied you with subsets, cartesian product or even power sets and the only thing you ached for was the sound of the schoolbell to indicate the end of the lesson ? Or perhaps you wondered who in the world did ever come up with that and why ?
Find out all the answers in this new article in the Articles Forum and be rewarded with a HP-50G program to calculate power sets.
Best regards
