We just learned all about light microscopy, which was the standard until the middle of the 20th century, and remains tremendously useful today. But as we began to learn more about the microscopic world, using light microscopes that could visualize individual cells, we started to become curious about structures that are smaller than a cell, some details of which were difficult to visualize and study under standard light microscopes. Fortunately, electron microscopy, developed in the 1930s and 40s, proved to be much more powerful and allowed scientists to view these smaller structures. Some electron microscopy techniques employ a resolution of 0.2 nanometers, which is more than 1,000 times better than light microscopy. With this higher resolution, electron microscopes are able to magnify their specimen up to 1,000,000 times their original size, allowing researchers to study proteins insid
