[QUOTE]Originally posted by Mike111: [QB] fawal - You make such a pathetic supremacist - you source your foolishness to a forum page??? I had hoped to get some enjoyment out of kicking your pale butt around these pages for a while, but you are pure ignorant bullsh1t, incapable of providing anything worthwhile to argue about. And you don't even comprehend your own quotes. fawal Quote: - In fact, some of the calculations in the mathematical papyri are quite complex. Moreover, it would be wrong to suppose that what survives in such [b]student manuals[/b] represents the sum total of ancient Egyptian mathematical knowledge. {The repository of Egyptian knowledge - the Alexandria Library - was destroyed by a fire started by Whites in 48 B.C.} This was of course AFTER Whitie had transcribed all knowledge contained within, and carried it off to their newly conquered lands of Greece and Italy. Them being originally ignorant and illiterate Nomads, they needed to steal everything that they could get their hands on. This, because initially, they didn't know how to make anything that they had taken from the Black Europeans work! The Berlin Papyrus The Berlin Papyrus 6619, commonly known as the Berlin Papyrus is an ancient Egyptian papyrus document from the Middle Kingdom. This papyrus was found at the ancient burial ground of Saqqara in the early 19th century CE. The papyrus is one of the primary sources of ancient Egyptian mathematical and medical knowledge, including the first known documentation concerning pregnancy test procedures, and is thus part of the medical papyri. The Berlin Papyrus contains a problem stated as "the area of a square of 100 is equal to that of two smaller squares. The side of one is ½ + ¼ the side of the other." The interest in the question may suggest some knowledge of the Pythagorean theorem, though more likely the data shows a straight forward solution of two second degree variables stated as one unknown, and not two unknowns, as reported by Scott Williams: "100 square cubits is equal to that of two smaller squares, the side of one square is 1/2 + 1/4 of the other. What are the sides of the two unknown squares. In modern terms we would express this as x2 + y2 = 100 and x = (3/4)y. What are x and y? A modern solution in this form might be ((3/4)y)2 + y2 = 100 implies (1 + 9/16)y2 = (25/16)y2 = 100 implies y2 =(16/25)100 = 64 implies y=8 and x= (3/4)8 = 6. However, most translators believe the egyptians viewed this problem the way we do the simultaneous equations x2 + y2 = 100 4x - 3y = 0 What are x and y? Here was their solution. Assume the square of the first side (y) to be 1 cubit. Then the other side (x) will be 1/2 + 1/4. Then y2 = 1, and using Egyptian multiplication we determine x2 with 1 1/2 + 1/4 1/2* 1/4 + 1/8 1/4* 1/8 + 1/16 1/2 + 1/4 1/4 + 1/8 + 1/8 + 1/16 = 1/2 + 1/16 So x2 = 1/2 + 1/16. Thus, x2 + y2 = 1 + 1/2 + 1/16. Now (1 + 1/2 + 1/16)1/2 = 1 + 1/4 and (100)1/2 = 10 (we will discuss square roots later). Divide 10 by 1 + 1/4 and you get 8 (see the method of problem 24). So we get y=8. The Berlin Papyrus contains damage here so we can at best assume the solution for x was to divide 8 by 1/2 + 1/4 (as in the method of problem 24) to achieve x=6. [/QB][/QUOTE]
