The third video from Corning’s Museum of Glass shows that the path to science is not always smooth and that learning from mistakes is the norm. The original 200 inch pyrex disk for the Palomar primary did not go according to plan and had to be recast.

The Web of Stories project finds legends of many disciplines and lets them speak at length about their lives and careers. For years, one could only watch these on the project website and embed up to five videos. This was an unfortunate limitation since these interviews are broken into well over a hundred short segments. Now, WoS has uploaded a large fraction of its library to its Youtube channel with embeddable playlists.

The breadth of their accomplishments and their constancy over decades is astonishing, their modesty likewise even though none have anything to be modest about.
