Ishango bone The Ishango bone is a bone tool, dated to the Upper Paleolithic era. It is a dark brown length of bone, the fibula of a baboon, with a sharp piece of quartz affixed to one end, perhaps for engraving. It was first thought to be a tally stick, as it has a series of what has been interpreted as tally marks carved in three columns running the length of the tool, but some scientists have suggested that the groupings of notches indicate a mathematical understanding that goes beyond counting. It has also been suggested that the scratches might have been to create a better grip on the handle or for some other non-mathematical reason. Out of Body Experiences Out of body experiences (OBEs or OOBEs) involve the vivid sensation of moving outside your physical body and sometimes traveling far beyond it. OBEs are most likely to occur when you are asleep, meditating or practicing wake-induced lucid dream exercises. Indeed, many dream explorers agree that out-of-body phenomena are extensions of the lucid dream experience. Around 1 in 10 people have experienced an OBE at some time in their lives - and some people have them frequently. There are many ways to induce an OBE and we'll look at a practical technique for doing so at the end of this article. The Link Between OBEs and Lucid Dreams

Time Travel and Modern Physics First published Thu Feb 17, 2000; substantive revision Wed Dec 23, 2009 Time travel has been a staple of science fiction. With the advent of general relativity it has been entertained by serious physicists. But, especially in the philosophy literature, there have been arguments that time travel is inherently paradoxical. The most famous paradox is the grandfather paradox: you travel back in time and kill your grandfather, thereby preventing your own existence. To avoid inconsistency some circumstance will have to occur which makes you fail in this attempt to kill your grandfather.
The 5 Strangest Things Evolution Left in Your Body If you don't believe in evolution, you have to spend a lot of time wondering about the useless shit the creator threw into our bodies. Why don't our wisdom teeth fit in our heads? Why do we need an appendix? The answer is that evolution is a sloppy and haphazard process. Take a close look at your body and you'll see some of the leftover junk. Like...
Shortcut When his wife grew ill in the early 1960s, Indian farmhand Dashrath Manjhi took her from their home in Gelaur to the hospital in the neighboring town of Wazirganj.

Ancient Hunter-Gatherers Kept in Touch Until about 8500 years ago, Europe was populated by nomadic hunter-gatherers who hunted, fished, and ate wild plants. Then, the farming way of life swept into the continent from its origins in the Near East, including modern-day Turkey. Within 3000 years most of the hunter-gatherers had disappeared. Little is known about these early Europeans. But a new genetic analysis of two 8000-year-old skeletons from Spain suggests that they might have been a remarkably cohesive population both genetically and culturally—a conclusion that other researchers find intriguing but possibly premature.
