A colleague called my attention to this post over at Langer.com’s 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 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.
