I am in highschool, but many of these people are incredibly educated and smart, and come from incredibly esteemed backrounds. I sometimes feel very small and insignificant in comparison. I think PF will change the world one day, Hey, maybe i will be the one to change it
The learned ones span from high school kids to old men(myself included- old anyhow). Education from HS to PHD and physics/chem/other researchers I believe. And from many different countries in europe, asia, and the americas.
