The Vault of the Heavens Taught by James B. Kaler (Portable Professor series)

Not one of the better offerings in the Portable Professor series. While quite informative, it was full of way too many instances that required visuals. Professor Kaler repeatedly described objects as “about this big” or as moving “like this”. I believe that taking a class from him in person would be fascinating and very enjoyable, but this did not translate well in the audio format.
