    What a coincidence this subject could come up.

    Here is an experiment on eye resolution.

    I was watching a documentary yesterday on the Battle of Jutland. One of the key matters was communication between two groups in the British Navy. Admiral David Beatty commanded a group of battlecruisers (lightly armoured battleships) and Admiral John Jellicoe commanded the larger Grand Fleet with battleships. Beatty's group was ahead of Jellicoe's group when a group of German warships were sited. Beatty signaled Jellicoe's group by the old traditional flag/penant method (too early for radio) and took off toward the German ships. Jellicoe (and his watchmen) did not see the Beatty's signal and actually continued away from Beatty.

    The point was that Beatty was too far for reliable communication using the flag/penant method.
