The resulting oxide was supposed to possess marvelous powers, and it was thought that there resided within it the individualities of the various metals -that in it their various substances were incorporated. History of Alchemyįrom an early period the Egyptians possessed the reputation of being skillful workers in metals, and, according to Greek writers, they were conversant with their transmutation, employing quicksilver in the process of separating gold and silver from the native matrix. To this name the Arabs affixed the article al, resulting in al-khemeia, or alchemy. Wallis Budge, in his Egyptian Magic, however, states that it is possible that alchemy may be derived from the Egyptian word khemeia, "the preparation of the black ore," or "powder," which was regarded as the active principle in the transmutation of metals. The Aryan root is ghu, (to pour), whence comes the modern word gush. One highly possible origin is the Arabic al (the) and kimya (chemistry), which in turn derived from late Greek chemeia (chemistry), from chumeia (a mingling), or cheein (to pour out or mix).
There is also considerable divergence of opinion as to the etymology of the word. There is considerable disagreement as to which, the scientific or the philosophical, is the dominant aspect and the manner in which the two were integrated (which to some extent varied tremendously from alchemist to alchemist). Alchemy is also the name of the Gnostic philosophy that undergirded the alchemical activity, a practical philosophy of spiritual purification. Finally, for good measure, I used the dwell locations to generate trade areas incorporating the closest 75% of those points, to give the client a visual of where the bulk of his customers were coming from.The art and science by which the chemical philosophers of medieval times attempted to transmute the baser metals into gold and silver. These were the "traffic drivers" the client was looking for. I used FME's ability to compare adjacent rows to figure out how far a phone traveled in a certain time period and filter out "on the road" pings, leaving only those locations where a phone "dwelled" for a period of time.
Using FME, I created workflows to figure out which phones belonged to employees and filter them out. Unfortunately, there's a lot of noise in that data: phones belonging to employees, not customers "pings" located on highways, in transit or pings in the parking lot of your store.
You can obtain location information for smartphones that have visited your store, and in that data you see where each phone went in the hour before, and the hour after, the store visit. UberMedia collects (and sells) smartphone location "pings" recorded whenever an associated smartphone app serves you an ad. In my internship, I was faced with a challenge: a client with a chain of restaurants wanted to know if he could use UberMedia smartphone location data to discover where his customers were coming from, how far they traveled, and what nearby businesses were driving traffic to his restaurants. But what can anyone DO with that much data? Can you create something meaningful from that ocean of noise?
