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.
Origins. Ballet originated in the Italian Renaissance courts of the 15th century. Noblemen and women were treated to lavish events, especially wedding celebrations, where dancing and music created an elaborate spectacle. Dancing masters taught the steps to the nobility, and the court participated in the performances.
