Trying to decide if it is worth including diagrams and formulas in the empty space of my celestial sliderule (now with lunar timekeeping on the reverse side)

A Navy Curtiss Helldiver (SB2C) is snapped against the background provided by its carrier as it returns from a strike at Jap shipping. Far below other planes are being spotted on the flight deck to which the SB2C will soon return.

The motion of its props causes an "aura" to form around this F6F on USS YORKTOWN. Rapid change of pressure and drop in temperature create condensation. Rotating with blades, halo moves aft, giving depth and perspective.

This short paper by Lander and Parkin from 1966 almost achieves xkcd's goal of a wordless proof.

COUNTEREXAMPLE TO EULER'S CONJECTURE ON SUMS OF LIKE POWERS BY L. J. LANDER AND T. R. PARKIN Communicated by J. D. Swift, June 27, 1966 A direct search on the CDC 6600 yielded 27^5 + 84^5 + 110^5 + 133^5 = 144^5 as the smallest instance in which four fifth powers sum to a fifth power. This is a counterexample to a conjecture by Euler that at least n nth powers are required to sum to an nth power, n>2.
