I love symbols, and I love spirals and how they are used in architectural symbolism. The following videos are not about architectural symbolism, but the principles that are presented are worthy of consideration on a whole myriad of levels.
Vi Hart, the woman presenting the videos talks a little fast which can be a little irritating but I love how she explores spirals so these are definitely worth the watch. All the information builds up to a very interesting theory as to why these numbers appear in nature and I think it’s spot on.
There are some really interesting implications behind what she presents here that apply to many different topics, but I’ll let you ponder those things for yourself ;)
