POPSThe Mathematical Lives of Plants The seeds of a sunflower, the spines of a cactus, and the bracts of a pine cone all grow in whirling spiral patterns. Remarkable for their complexity and beauty, they also show consistent mathematical patterns that scientists have been striving to understand. ... Scientists have puzzled over this pattern of plant growth for hundreds of years. Why would plants prefer the golden angle to any other? And how can plants possibly "know" anything about Fibonacci numbers? For the first time, scientists have found convincing biochemical mechanisms responsible for the interlocking spiral growth patterns seen in many plants. (The Romanesco broccoli plant is a striking example.) The video of the experiment with magnetized liquid iron droplets demonstrates how the geometry of such growth could occur in nature.

POPSSaudi woman to be beheaded for being a "witch" Being beheaded by sword in a public place... For being a "witch" or practising "witchcraft"... Welcome back to the Middle Ages: "Burn the witch!" or "Behead the witch!", by the name of God. Correct me if I'm wrong, Saudi Arabia is a close ally of the US, who enthusiastically invaded Iraq to bring "human rights and democracy" to Arabs, right?

POPSCaral: The first city in the New World A brief article on a stunning archaeological discovery in South America. About six years ago, Peruvian/American archaeologist Ruth Shady , introduced the "oldest city in America" to the world. It was Caral; an ancient city on the Pacific coast of Peru, with trade centers, temples and a pyramid complex not less impressive than its counterparts in Mexico and Guatemala. The most exciting thing about Caral was its age: The city was carbon dated to ca. 3000 BCE, which strongly suggested a radical change in history textbooks. All evidence show Caral was not an exception in the region and there are many more ancient towns, waiting to be discovered. Another interesting thing about Caral is, its surprisingly peaceful social order. Archaeologists found no city walls, no forts, no signs of an army and even not a single weapon in Caral. Once again, thanks to Ruth Shady for this fantastic discovery.

POPSNo Moses, no Joshua, no (so-called) monotheism "In the text you have the story of the Israelites coming from outside, and then besieging the Canaanite cities, destroying them and then becoming a nation in the land of Canaan. Whereas archaeology tells us something which is the opposite. According to archaeology, the rise of early Israel is an outcome of the collapse of Canaanite society, not the reason for that collapse." * The principle of monotheism (the worship of a single deity), established first by the Jews and later to form the foundation for both Christianity and Islam, took much longer to take root than most people assume. In fact, the archaeological discovery of troves of household idols in ancient Canaanite towns and cities proves that the Israelites practiced polytheism long after they had been thought to have discarded the practice.

POPSGiveaway of the day - Free Licensed Software interesting marketing technique... & free software ... !!! I guess I'll make a daily visit here The idea behind this initiative is that many sites and publishers offer trial downloads; but only we offer giveaway downloads. What does that mean?

POPSThe universe... we're not the first I have always said there can't be something from nothingness without a grand creator. I am not sure which side of the fence I sit on now but in order to support my thoughts of the ever expanding and contracting universe, let me say that I don't feel time is what we think it is. :)
