thought for the day/ the way we think about numbers and geometry is culturally influenced

This article says on the one hand, there is no universal mathematics, and on the other that we do so based on our cultural upbringing.

Yes, there's different cultures that have their kids grow up thinking about things(almost as if the mind comes with ingrained notions); and yes, mathematics is probably not 'out there'; but, we do learn from the very beginning from our current perspective.

When mankind first starting thinking about the universe, they thought the earth was the center of the universe, that the earth was flat because that's what our senses show us when we first start looking at it.
Genius is overcoming our cultural upbringing!(like religion)
