Race I like race. I know it sounds odd, even politically incorrect. But I really enjoy the differences among people around the world. One aspect of this is all our different cultures. But another is all our different physical types. I get a kick out of reading and thinking about how we got to look the way we look, where our characteristics came from, why they are there at all. The races are definitely not "subspecies." Because the concept of race has been confused so thoroughly with our terrible history of racism, many avoid the term altogether. Skin Speaking of the "red" man, the "white" man, and the "black" man, skin color is perhaps the first characteristic we think of when we think of race. Skin, hair, and eye color are due to relative amounts of melanin. The experts are pretty much in agreement about how the varieties of skin color came about. Once people were out of Africa, there was a lot more variation in levels of sunlight. Hair Eyes Blood Genes Another approach uses the term lineages.
50 Things Everyone Should Know by Mark and Angel Self-reliance is a vital key to living a healthy, productive life. To be self-reliant one must master a basic set of skills, more or less making them a jack of all trades.

Electronic Text Center, University of Virginia Library | Table of Contents for this work | | All on-line databases | Etext Center Homepage | In Lecture V we found reason to think that the ultimate constituentsn27 of the world do not have the characteristics of either mind or matter as ordinarily understood: they are not solid persistent objects moving through space, nor are they fragments of "consciousness." The physical classification of particulars collects together all those that are aspects of one "thing." This gives us, so far, only those particulars which constitute one thing at one time. aspects through the laws of perspective. The definition of a "momentary thing" involves problems concerning time, since the particulars constituting a momentary thing will not be all simultaneous, but will travel outward from the thing with the velocity of light (in case the thing is in vacuo). photographic plate. 27. 28.
Goody on the Differences between Orality and Literacy | Chapter 1: Literacies on a Human Scale | Literacies | New Learning Cambridge Anthropologist Jack Goody writes about some of the differences between oral and literate societies: The written word does not replace speech, any more than speech replaces gesture. But it adds an important dimension to much social action. This is especially true of the politico-legal domain, for the growth of bureaucracy clearly depends to a considerable degree upon the ability to control ‘secondary group’ relationships by means of written communications. Indeed it is interesting to note that the terms in which Cooley originally defined the primary group are very close to those used for pre-literate societies. Other social institutions are affected more directly. Much of the discussion and much of our thinking about other cultures has been based on the misinterpretation of the nature of oral ‘tradition’.
Pythagorean cup Cross section Cross section of a Pythagorean cup. A Pythagorean cup (also known as a Pythagoras cup, a Greedy Cup or a Tantalus cup) is a form of drinking cup that forces its user to imbibe only in moderation. Credited to Pythagoras of Samos, it allows the user to fill the cup with wine up to a certain level. Form and function A Pythagorean cup looks like a normal drinking cup, except that the bowl has a central column in it – giving it a shape like a Bundt pan in the center of the cup. When the cup is filled, liquid rises through the second pipe up to the chamber at the top of the central column, following Pascal's principle of communicating vessels. Common occurrences A Pythagorean cup sold in Crete A Pythagorean cup sold in Samos Hero of Alexandria (c. 10–70 AD) used Pythagorean cups as hydraulic components in his robotic systems.
