Iced cherry tree
We are back to something like normal early spring weather in Minnesota, which means the temperature may drop below freezing. I have not looked up how low it got last night, but as of 7AM this morning it was 25oF/-3oC.

Astronomy in the Movies

Read the book, see the video
I loved them both.

The Woodwright’s Shop: Elizabethan Joint Stool with Peter Follansbee and Megan Fitzpatrick (Why didn’t PBS list her?). As you might expect, there are several references to Shakespeare in the video.
