Virtual event description:

Telescopes then and now. We have been watching the stars for centuries and our tools have changed dramatically since the time of Ptolemy and early astronomers. This panel will explore how tools and practices have changed over time.

Sajjad Nikfahm-Khubravan will trace the history of tools and ideas down from Greek astronomers to Islamic observers, and from the golden age of Islamic astronomy to European observers. Dallas Wulf will balance this historical tour with a talk on the powerful tools used by astronomers today. Join ROAAr and the McGill Space Institute for this special collaborative panel, and get a peek at some of the history of astronomy treasures in the McGill Library’s rare and special collections with librarian Lauren Williams.
