minus-squarechonglibloodsport@lemmy.worldlinkfedilinkarrow-up0·13 days agoPeople who lived before the invention of zero counted like that!

minus-squarechonglibloodsport@lemmy.worldlinkfedilinkarrow-up0·13 days agoThe idea of zero being a number rather than the absence of a number took a very long time to settle on. There’s a whole history book on the topic!
minus-squareApathy Tree@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up0·13 days agoI listened to an audiobook about the history of zero years ago (can’t remember the name, might be that one). I thought it would be dull enough to fall asleep to. It was not.
