Though fracking is used worldwide to extract gas and oil, a fracking boom has occurred recently in the United States, partly driven by concerns over energy security and the costs associated with imported oil and other fossil fuels.
Early history. The Viennese Waltz, so called to distinguish it from the Waltz and the French Waltz, is the oldest of the current ballroom dances. It emerged in the second half of the 18th century from the German dance and the LÃ¤ndler in Austria and was both popular and subject to criticism.
The polonaise comes from the French word for Polish to identify its origin among the Polish aristocracy, who had adapted the dance from a slower walking dance called chodzony. The polonaise then re-entered the scene and became an integral part of Polish music. Poland's five national dances (Mazur, Polonez, Kujawiak, Krakowiak, Waltz), as well as modern dance, contemporary dance and ballet are all widely performed today throughout the Polonia community.
