- July 18, 1853 - Dutch physicist Hendrik Lorentz is born. Lorentz received the 1902 Nobel Prize in physics for his work with Pieter Zeeman in discovering and defining the Zeeman effect. Lorentz is known best to posterity for creating a set of mathematical transformations for space and time under motion. These Lorentz transformations were ultimately used as part of Einstein's theory of relativity.
- July 16, 1888 - Dutch physicist Frederik "Frits" Zernike is born. Zernike received the 1953 Nobel Prize in physics for his invention of the phase contast microscope, which allowed the study of cells without the need of killing the cells through the "staining" process.
- July 16, 1945 - The United Success successfully tests an atomic bomb in New Mexico. This experiment is considered by many to initiate the atomic age.

- July 21, 1969 - Neil Armstrong and Edwin "Buzz" Aldrin become the first human beings to walk on the Moon's surface.
- July 16, 1994 - American theoretical physicist Julian Seymour Schwinger dies. Schwinger's work in the development of quantum electrodynamics resulted in the 1965 Nobel Prize in Physics, along with Richard P. Feynman.
- July 16, 1994 - Fragments of the Shoemaker-Levy 9 comet collide with the planet Jupiter, creating spectacular space images that quickly circulated around a nascient internet.
