New Atomic Bomb Photos - Unique

[Michael Fanelli]

These photos were taken using a 100 foot camera with an equivalent shutter speed of about 1/100,000,000 sec. I assume they are not faked. Take a look, it is stunning to see what the explosion looks just as it's happening, long before the famous mushroom cloud, blast, etc.

Frightening, awe inspireing, terror inducing.

Those photos are awesome. Edgerton was a genius. It's hard to even really comprehend what I'm looking at.

The ads on that page were heinous. Ouch. I almost had a seizure.

Wow. Just wow.

Doesn't look faked to me. The apparent smooth fireball we see in most photos is smoothed by motion and usually taken later than these.
I wonder how many other photos there are in this series that haven' t been released, and what they reveal about the trigger?
If the implosion trigger was uneven you would be able to deduce the layout from the uneven distribution of the shell in the very early images.
Perhaps a google image serach is needed ... very cool photos.

I have forgotten that there was such a thing as ads. I use Camino on my Mac and it has a advertisment blocker.

That is truly beautiful, yet extreamly frightning at the same time. I am sure glad I am not a Joshua Tree.

Wondered where I'd heard the name recently ...
"Dr. Harold E. Edgerton, professor at MIT and inventor of the electronic flash,"

The highest speed is really a sham, because the film is fixed around the periphery of the camera and a spinning mirror projects the image on the stationary film.
Add to that a high speed (electro-optical) shutter and you can get mayye 24 frames at 1 million fps.

The high speed camera here http://homepage.mac.com/andreaspape/...503/index.html is tantalisingly close, in fact it looks just like the descriptions of the rotating mirror design.
See the array of projection lenses and mirrors around the centre?
See what could be a film locator around the circular housing?
I reckon this is a high-speed explosion imaging camera.

Alternatives that use travelling film and swept image projection are somewhat slower, but can obviously work for a longer period.
The hard parts are getting the film up to speed without wasting it all, keeping running speed constant, and synchronised with the spinning shutter (or prism), and managing the output film.
Come to think of it - it's all hard

Amazing, thats all I can say about those images.

What adds?? I'm using FireFox.

When I was in the amy, I saw the real things. You would be shocked as how small they have become. But the only images that we were shown happened to be in color. Sorry I have no photos

Shocked? Not really.
I think the original Little Boy gun design was 50Kg target and 30Kg slug.
Only 2% of the fissionable material in the original bomb actually took part in the explosion.
So you ought to be able to make a bomb of that yield with only 2% of the material.
With some rather clever implosion mechanism of course.
Not quite the nuclear hand grenade, but yes, pretty small.

Did anyone take the kissing test?
