<p>Lindendragon: </p> <hr /> <div>The wheel was a revolutionary invention by the [[Mesopotamia|Mesopotamians]]. It reduced [[friction]] in movement by rolling. The wheel is ideal for transportation applications where it is generally important to waste as little [[energy]] as possible.<br /> <br /> == History ==<br /> <br /> The ancient Mesopotamians invented the wheel originally in the form of a potter’s wheel. It then developed into a solid wooden disk with a hole in the middle for an axle. To make the wheel lighter and more practical, the spoked wheel was developed. The [[Greece|Greeks]] used this type of spoked wheel. The [[Celts]] introduced a [[bronze]] rim around the outside of the wood to strengthen the structure. That was how the wheel remained, without major modifications, until the [[19th century|1800’s]] when rubber (made from latex) tyres started being developed. <br /> <br /> In 1845, Scotsman Robert William Thomson patented the vulcanized rubber pneumatic tyre in [[Scotland]]. Pneumatic means the tyre is made from reinforced rubber and filled with air to provide a &quot;...cushion of air to the ground.&quot; This type of tyre was originally used on bikes but soon moved on to the automotive world. To this day, pneumatic tyres are used on bikes and [[Automobile|automobiles]].<br /> <br /> The [[rubber tyre]] was never truly popularised until [[World War I]], when the combined forces of the [[Triple Ententé]] ([[Britain]], [[France]], and [[Russia]]) started using it for military vehicles against the [[Triple Alliance]] ([[Germany]], [[Austria-Hungary]], and [[Italy]]), before the incidence of [[trench warfare]] which would have made using [[vehicles]] useless for battle with the exception of the largely helpful [[tanks]]<br /> <br /> ==Alternatives to Wheels==<br /> There are many alternatives to using wheels for transportation over land.<br /> Different methods include:<br /> <br /> * Human body (running or walking)<br /> * Riding a horse or other mountable animal<br /> * Dragging (as with a sled in arctic conditions)<br /> * Electromagnetic trains (or similar technology)<br /> * Gondola<br /> <br /> [[Category:anthropology]]</div>
