Early ski poles were made of pine and bamboo, materials which today are used for novelty poles. [4] US patents for steel ski poles began in 1933 when John B. Dickson invented a new design calling for the use of steel as the shaft material. [6] This construction was superseded by Edward L. Scott, who is credited with popularizing the lightweight aluminum ski pole in 1959, deriving his modern design from golf club shafts. [7] [8] This new stiff and lightweight pole made it easier for skiers to pole-plant and initiate fast, short turns. [8]

We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta's pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications. The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery.
