Mr. J.N. is currently on leave from his post as mathematics tutor, perhaps permanently. He has retreated to an unknown location to work on his magnum opus (Latin, "great work") and learn a little bit of various languages. He studies mathematics, physics, and philosophy in his free time, and is keenly interested in the creation-evolution debate. Mr. J.N. has used Edmodo since he was a student at Edmodo's inception, and frequently recommends it as a social network superior to FaceBook, an upstart company about which he knows and cares nothing.
