Two links of interest today. First off, Josh pointed me to this fantastic size comparison of various planets and stars. Some of the image resolution is prettier than on other pictures, but the concept is great. The thought of sitting some size comparison planets on my desk is a lot of fun.
The second is an issue where museum preservation of biological species meets art. An ineffectively preserved shark is shrinking, so the artist wants to replace it with one more properly preserved. Not a bad idea. The question then becomes whether or not this modification changes the value of the art. Heck, does the rotting of the current shark in the container change the value of the art? Big questions.
