A colleague called my attention to “this post”:http://www.langner.com/en/2011/12/07/the-prez-shows-his-cascade-shape/ over at Langer.com’s “blog.”:http://www.langner.com/en/blog/

The post uses a photo from Iranian President Ahmadinejad’s 2008 visit to the Natanz FEP to determine the shape of the 164-centrifuge cascades. Specifically, it uses “an image”:http://www.langner.com/en/wp-content/uploads/2011/12/Natanz-SCADA-detail2.jpg from “the SCADA screens in Natanz’ control room.”

I won’t attempt to reconstruct the argument any further. Go ahead and read the whole thing.
