Trinity Test - First Atomic-Bomb Explosion

On Monday, July 16, 1945 - at 5:30 a.m., Mountain War Time - the United States tested the world's first atomic bomb.  It is said (although the source has not been verified) that Robert Oppenheimer called the explosion the "Trinity Test," based on a poem (the Fourteenth Holy Sonnet) of John Donne.

This clip of the test (filmed at 10,000 yards from "ground zero")  is one of the views of that explosion.

Beginning of John Donne's Holy Sonnet XIV:

Batter My Heart, Three-Personed God

Batter my heart, three-personed God; for, you
As yet but knock, breathe, shine, and seek to mend;
That I may rise, and stand, o'erthrow me, and bend
Your force, to break, blow, burn, and make me new.
