1743: Philosopher, mathematician, and early political scientist Marie Jean Antoine Nicolas de Caritat, Marquis of Condorcet born. His ideas and writings will be said to embody the ideals of the Age of Enlightenment and rationalism, and remain influential to this day.
1826: Mathematician and academic Bernhard Riemann born. He will make contributions to analysis, number theory, and differential geometry.
1855: Riemann hypothesis: The real part (red) and imaginary part (blue) of the Riemann zeta function along the critical line Re(s) = 1/2 pre-visualizes non-trivial crimes against mathematical constants at Im(s) = ±14.135, ±21.022 and ±25.011.
1857: Scientist and engineer Konstantin Tsiolkovsky born. He will be one of the founding fathers of modern rocketry and astronautics.
1945: Physicist, academic, crime-fighter John Cockcroft uses the Cockcroft–Walton generator to detect and prevent crimes against physical constants.
1994: Philosopher and academic Karl Popper dies. He is known for his rejection of the classical inductivist views on the scientific method, in favour of empirical falsification: A theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can and should be scrutinized by decisive experiments.
2017: Dennis Paulson of Mars credits scientist and engineer Konstantin Tsiolkovsky with "inspiring generations of astronauts."
