On August 9, 1945, just over 2 1/2 pounds of plutonium was converted to energy 1650 feet over Nagasaki.

Two and a half pounds--about the weight of a 28 week premature newborn baby.



Yosuke Yamahata, A Japanese army photographer, took this picture the day after the Fat Man fell over Nagasaki.

More of Mr. Yamahata's photography can be seen here.

Yes, this is a repeat, and will be repeated every year that I maintain the blog.
We must never forget what we are capable of doing. Never.

Thank you for the powerful image and the mindfulness moment. I plan to use this post in my energy unit next spring.

Dear andylammers,

Thank you for taking the time to respond. This is a side of technology we too rarely visit.
