The Wall

“What a dear old wall that is that runs along by the river there! I never pass it without feeling better for the sight of it. Such a mellow, bright, sweet old wall; what a charming picture it would make, with the lichen creeping here, and the moss growing there, a shy young vine peeping over the top at this spot, to see what is going on upon the busy river, and the sober old ivy clustering a little farther down! There are fifty shades and tints and hues in every ten yards of that old wall. . . . It looks so peaceful and so quiet, and it is such a dear old place to ramble round in the early morning before many people are about.” Jerome K. Jerome, “Three Men In A Boat (To Say Nothing of the Dog)” Ch. 6 (1889)

Finished Reading: Ptolemy

-

 

Finished reading Book 1 (Sections 1-8) and Book 3 of The Almagest by Ptolemy (c 100. - 170 AD).  Ptolemy, known for his contributions in the fields of mathematics, geography and astronomy is perhaps most well known for the idea of an earth-central universe though the idea was not unique to him. While Ptolemy was wrong in some areas of astronomy, he should be credited for the depth and breadth of the science his attempts. For example, his argument for the spherical shape of the earth is held against the possibility that the earth could be no other shape: flat, square, pyramid or cylindrical. Ptolemy held that our seasons are controlled by the proximity of the sun to the earth as it circles the earth—closer in summer than in winter. Contrasted against Aristotle who held that heavenly bodies consisted of four elements (earth, air, fire, water), Ptolemy recognized differences in  stars and planets  they orbit, fixed in their enveloping shell.

The Smooth-flowing Life

Legend has it that the astronomer Ptolemy (1st century A.D.) suggested that falling stars were caused by the gods moving in the heavens, thus knocking stars out of their places. Somehow people reasoned that that if the gods were moving, they must be getting close to earth so they would lift their "prayers" or "wishes" (literally, "desires") whenever they saw the stars falling in hopes the gods would notice and grant a favorable answer. But how does one wish on falling star? Once you see it, it's gone before the wish or prayer can be made! The answer is simple: meteor shower. That's how to get your wish. Mrs. Ann Hodges had a wish fall right into her lap. Sort of. In 1954 Mrs. Hodges was sleeping on the couch when a 8 1/2 pound meteorite fell through her house and into her living room where it bounced off the radio and struck her left hip leaving her with a bruise. Not sure what she was wishing, but that's not how to do it. Epictetus hel...
