This One's for Pepys

[rinue]

The sort of thing historians get excited about when they read old journals: when I went to the dentist last week, they took digital x-rays of my teeth. For my whole life, x-rays have been on film - little sharp rectangles I hold in my mouth while a large machine fires radiation at my teeth. This time, I bit down on a reusable digital sensor instead of film, and the image came up immediately on a computer screen, at a variety of resolutions. In the case it wasn't a clear image, it could be retaken immediately. The ray gun and lead apron were the same.
