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 polka was introduced in England by the middle of the nineteenth century. However, it did not achieve the popularity it had achieved on the Continent. By this time, it had also reached the United States.he dance was first introduced into the ballrooms of Prague in 1835. The name of the dance (pulka) is Czech for half-step, referring to the rapid shift from one foot to the other. In 1840, Raab, a dancing teach of Prague, danced the polka at the Odeon Theatre in Paris where it was a tremendous success.
