🔬 The World Invisible to the Naked Eye
For thousands of years, humans could only see what their eyes allowed them to see. Then in the late 1500s, Dutch lens makers began creating the first microscopes, opening up an entirely new world of discovery. When Robert Hooke peered through his microscope at a slice of cork in 1665, he saw tiny box-like structures that he called "cells" - launching the field of cell biology.
Today, microscopes are essential tools in biology, allowing us to explore the intricate structures that make up all living things. From the delicate organelles inside a single cell to the complex tissues of multicellular organisms, microscopy reveals the hidden architecture of life.
