Die ersten Millisekunden einer Atomexplosion

Irgendwie ist es ein wenig schockierend, dass man selbst in einer explodierenden Atombombe noch etwas SchÃƒÂ¶nes entdecken kann. Zumindest wenn man sich die ersten paar Millisekunden ansieht.
“Rapatronic” nannte sich die Technik, mit dere…

I believe that the 1/100,000,000 is fairly accurate. I will be looking in to this to see how it was done. You have to remember it was an atomic bomb. This is a series of three photographs.

1/10,000 of a second would not catch that photo, sorry.

Good catch, Zowie – I must admit, I quoted the website directly on that and had no idea on what the shutter speed equivalent of taking a blast 7 miles away with a 10 foot lens.

Wait – 10 foot lens? They *make* that?

That’s 1/10,000 of-a-second, please! The confusion probably comes from someone, at some point, saying “a hundred millionths of a second” and someone else hearing “a hundred millionth of a second”, something else entirely! Edgerton’s shutter was most likely a “curtain shutter” – a narrow slit in a piece of lightweight material. To achieve a 10-nanosecond exposure the shutter would have to be moving at something like 10 km/sec — which is Earth’s escape speed! Not likely.
