What reading level is Practical Talks By An Astronomer book?
To quickly assess the difficulty of the text, read a short excerpt:
If we were asked to sum up in one word what photography has accomplished, we should say that observational astronomy has been revolu- tionized. There is to-day scarcely an instru- ment of precision in which the sensitive plate has not been substituted for the human eye ; scarcely an inquiry possible to the older method which cannot now be undertaken upon a grander scale. Novel investigations formerly not even possible are now entirely practicable by photog- raphy ; and the end is not yet. Valua...ble as are the achievements already consummated, photog- raphy is richest in its promise for the future.
Astronomy has been called the " perfect sci- ence " ; it is safe to predict that the next gen- eration will wonder that the knowledge we have to-day should ever have received so proud a title.
