Electricity & Magnetism - Download free content from MIT Board Game: VIKINGS: The North American Saga This is an old Norse game that is found in many Viking and Norse sites. It consists of a board (which can be cardboard or even paper) and game pieces. Students can make their own board and playing pieces and challenge each other to games until there are two champions of the class. The appendix includes a starting board layout and information on the game. The Old Norse played and a lot of board and card games in the winter. Can you guess why? Hnefatafl (or hneftafl) [Nhev-eh-TAH-full] means the "king's board or game". SET-UP: Hnefatafl simulates a Viking raid. On the set-up diagram (above) attacking warriors are represented by the horizontal striped circles while the defenders are vertically striped. For our game, the attackers are made of antler disks, the defenders of glass drops, and the king is pewter. The attackers' goal is to capture the king. This can be done by surrounding the king on all four sides of the center square. Players play only one piece at a turn.

100 Very Cool Facts About The Human Body The Brain The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.The brain operates on the same amount of power as 10-watt light bulb. Hair and Nails While they’re not a living part of your body, most people spend a good amount of time caring for their hair and nails. Facial hair grows faster than any other hair on the body. Internal Organs Though we may not give them much thought unless they’re bothering us, our internal organs are what allow us to go on eating, breathing and walking around. Bodily Functions Senses

Twisting Radio Waves Could Give Us 100x More Wireless Bandwidth | Light As more people stream video to their mobile devices, wireless bandwidth is becoming an increasingly precious commodity. Data traffic increased 8,000 percent in the past four years on AT&T’s network alone. In trying to avoid what the Federal Communications Commission calls a “looming spectrum crisis,” telecommunications companies are lobbying the government to assign them more spectrum space in the 300- to 3,000-megahertz range, the sweet spot for wireless communication. But Italian astrophysicist Fabrizio Tamburini says a solution may lie in making better use of the frequencies already in use. In a recent paper, he demonstrated a potential way to squeeze 100 times more bandwidth out of existing frequencies. The idea is to twist radio waves like corkscrews and create multiple subfrequencies, distinguished by their degree of twistedness. The next step is to design small, cheap smartphone antennas that can transmit and receive the warped signals.
