The Backwards Image of Yukawa and Feynman

The first episode of a series of my essays on Richard Feynman [1] is about the photo of Yukawa and Feynman that appeared backwards in Physics Today [2]. Last year I planned to make a book [3] by including the above series of essays, and wanted to use that photo by getting permission from AIP. So I searched it at AIP Emilio Segrè Visual Archives.

Bravo! The image was kept as printed previously [4], in spite of the fact that Peter Lee pointed out the backwards printing in a letter to the editor of Physics Today [5].

These days the normal image is simply gotten from the backwards one by a photo editing program, so that I was afraid that it might have been saved as the normal image. Permission to use the photo can be made easily at the Web site of Emilio Segrè Visual Archives. However, if the photo had been kept as the normal image, it should have been necessary for me to make special contact with them to get permission of the modified use of it, i.e., the use of horizontally flipped image as printed in [2] by describing the reason that my essay refers to . . .

By the way, you can also see the same photo printed backwards in the books [6] and [7] (in fact, the first mention of the photo in my essay is made of the one in [6]).
