Today is the anniversary of the atomic bombing of Hiroshima. At left is a photo I made on the day of the 41st anniversary, looking through the canopy of the Memorial Cenotaph to the A-bomb dome in the distance. The dome capped the city's industrial exhibition hall in 1945 and was directly beneath the atomic bomb, which exploded in the air. The dome survived because it had a steel framework and wasn't subjected to lateral blast pressure; other buildings near ground zero were destroyed. People caught outside buildings were vaporized, some leaving only their shadows on sidewalks and stone steps.
