- Interstate State Park (mnopedia.org)
The Interstate State Park, located on 295 acres in Taylors Falls, is the second-oldest state park in Minnesota. Created in 1895, its unique topography and geological history draw many visitors to the area. It is the first park in the United States to be located in two states, Minnesota and Wisconsin, with the St. Croix River serving as the border. The two parks are operated separately by the states’ Departments of Natural Resources.
- Ptolemy (Wikipedia)
Claudius Ptolemy (/ˈtɒləmi/; Greek: Πτολεμαῖος, Ptolemaios; Latin: Claudius Ptolemaeus; c. 100 – c. 170 AD) was a Roman mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the Almagest, although it was originally entitled the Mathēmatikē Syntaxis or Mathematical Treatise, and later known as The Greatest Treatise. The second is the Geography, which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the Apotelesmatika (lit. “On the Effects”) but more commonly known as the Tetrábiblos, from the Koine Greek meaning “Four Books”, or by its Latin equivalent Quadripartite.
