Wondrous devices
The Hudson River Museum's 'Wondrous Devices' exhibition explores the various scientific devices and instruments that helped shape what people now know about the Earth, the stars and planets. It's on display through Dec. 30. For people on the go in the 19th century, 'Walking Cane' allowed them to sightsee or look up at the night sky with a simple telescope held together by a walking cane.
