- Johannes Kepler (December 27 1571 – November 15 1630) was a German Lutheran mathematician, astronomer and astrologer, and a key figure in the 17th century astronomical revolution. He is best known for his laws of planetary motion, which provided one of the foundations of Isaac Newton’s law of universal gravitation.
- Denny Mountain (summitpost.org)
Denny Mountain is the prominent peak seen to the northwest of Snoqualmie Pass and to the north of I-90. The mountain consists of a one-mile long ridgeline oriented to the NNW with many jagged outcrops. The southern buttress of Denny can be seen towering above I-90 as the road approaches the pass from the west but the actual highpoint of the summit is hidden from eastbound freeway vantage points. The summit can be spotted by westbound drivers from the pass. Its NE face is home to the notoriously challenging Alpental ski area that boasts of having only 3% “easy” slopes and 75% “expert” with 22% in between.
Geometry has two great treasures: one is the Theorem of Phythagoras, the other the division of a line in extreme and mean ratio. The first we can compare to a mass of gold; the other we may call a precious jewel.
Johannes KeplerI much prefer the sharpest criticism of a single intelligent man to the thoughtless approval of the masses.
Johannes KeplerI used to measure the heavens, now I measure the shadows of Earth. Although my mind was heaven-bound, the shadow of my body lies here.
