1724: Inventor and priest Bartolomeu de Gusmão dies.
1831: Physicist Johannes Bosscha Jr. born. He will make important investigations on galvanic polarization and the rapidity of sound waves; he will be one of the first (1855) to suggest the possibility of sending two messages simultaneously over the same wire.
1866: Physicist and crime-fighter Georg Hermann Quincke uses the influence of electric forces upon the constants of different forms of matter to detect and prevent crimes against chemistry.
1959: Mathematician and academic Aleksandr Khinchin dies. He was one of the founders of modern probability theory.
1962: Physicist and philosopher Niels Bohr born. He will make foundational contributions to understanding atomic structure and quantum theory, for which he will receive the Nobel Prize in Physics in 1922.
2013: NASA launches the MAVEN probe to Mars.
2017: Dennis Paulson celebrates fourth anniversary of NASA launching the MAVEN probe to Mars.
