Bernie Ecclestone
Ecclestone is the president and CEO of Formula One (F1) Management and F1 Administration. Originally a racer, he gave up the sport after an accident in 1951, later returning as a manager and, eventually, a team owner. In the 1970s, he negotiated broadcasting rights with major TV networks that helped market the sport worldwide. In 2004, his home became the most expensive house ever sold when a steel magnate bought it for how many millions of dollars?Czechoslovakia Gains Independence
The creation of Czechoslovakia was the culmination of the long struggle of the Czechs against their Austrian rulers. Benefiting from a liberal, democratic constitution, the new republic appeared to have a bright future. Yet the new state was far from being a stable unit. With its antagonistic and nationalistic ethnic elements, it reflected the inherent weakness of the Hapsburg empire. How did the nationality problem lead to a European crisis on the eve of WWII?Ancient Footprints Found in Mexico Desert
A trail of 13 fossilized footprints was found running through a valley in a Mexico desert. The footprints, which were embedded in a white rock called travertine, were made by hunter gatherers in the Coahuila valley of Cuatro Cienegas. They are believed to be between 10,000 and 15,000 years old. The oldest discovered footprints in the Western hemisphere are in Chile, and are believed to be 13,000 years old.Basket Weaving
Basketry is the art of weaving flexible materials to form vessels or other objects. The materials used include twigs, bamboo splits, rattan, raffia, grasses, and straw. Basketry is an ancient craft, and baskets used for storing grain in 4000 or 5000 BCE have been excavated in Egypt. The tombs of Etruria have also yielded ancient specimens that, along with much later Roman baskets, display weaving strokes still in use. What is the difference between "coiled" basketry and "plaiting" basketry?
