WebShow Daniel and Jorge Explain the Universe, Ep Why can't two electrons be in the same place? - Apr 12, 2024 WebThis came in 1931, with the invention of the electron microscope. Beams of electrons are focused on a sample. When they hit it, they are scattered, and this scattering is used to recreate an image. An electron microscope can be used to magnify things over 500,000 times, enough to see lots of details inside cells.
