1867: 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.
1932: In Washington, D.C., police fire tear gas on World War I veterans, part of the Bonus Expeditionary Force, who attempt to march to the White House.
