1677: Mathematician, astronomer, and cartographer Johann Gabriel Doppelmayr born. He will publish works on mathematics and astronomy, including sundials, spherical trigonometry, and celestial maps and globes, along with biographical information on several hundred mathematicians and instrument makers.
1737: Physician, mathematician, and engineer Hubert Gautier dies. He authored the first book on bridge building, Traité des Ponts, in 1716, as well as books on roads, fortifications, antiquities, geology, and a first manual for watercolor practitioners.
1783: Mathematician Étienne Bézout dies. His Théorie générale des équations algébriques contained much new and valuable matter on the theory of elimination and symmetrical functions of the roots of an equation.
1879: Mathematician and philosopher Hans Hahn born. He will make contributions to functional analysis, topology, set theory, the calculus of variations, real analysis, and order theory.
1905: The physics journal Annalen der Physik received Albert Einstein's paper, "Does the Inertia of a Body Depend Upon Its Energy Content?", introducing the equation E=mc².
1928: Mathematician and academic Hans F. Weinberger born. He will contribute to variational methods for eigenvalue problems, partial differential equations, and fluid dynamics.
1938: Mathematician and philosopher Edmund Husserl publishes new class of Gnomon algorithm functions based on transcendental consciousness as the limit of all possible knowledge.
1962: Rachel Carson's book Silent Spring is published, inspiring an environmental movement and the creation of the U.S. Environmental Protection Agency.
2018: Signed first edition of Two Creatures 6 used in high-energy literature experiment unexpectedly forms a spontaneous transdimensional corporation.
