Quote by Antonie van Leeuwenhoek

"I have always endeavored to use my eyes as accurately as possible."

"The more one observes, the more one sees."

"Nature is the greatest teacher if we are patient enough to listen."

"I do not pretend to know more than I can see with my own eyes."

"Education opens doors."

"Education opens doors to endless possibilities."

"I ain't got the education you got, bub."

"You can't put a price on history."
