I suspect the world would be better if that percentage were even greater.
Internet Archive: The telescope by Louis Bell
Poking around on archive.org, I found that Louis Bell’s classic work The Telescope was available for download. It is a pretty nice book, well worth reading if one has an interest in astronomy and telescopes. It is part history, part engineering, and part user’s guide. It also includes some great illustrations such as the one below of Newton’s first reflecting telescope. Enjoy!
