Ugears STEM lab Curvimeter
$21.99
Whether you are planning a cross-country bike ride or a hiking trip with your mates, trying to measure your forest jogging route or simply curious about how a real distance-measuring tool works, the new ‘Curvimeter’ STEM lab model from Ugears will satisfy all of these urges!
It comes in handy specifically when the lines which need to be measured are curved rather than straight (hence, the name) and a regular ruler is of no use. Before the birth of the internet and all the modern gadgets, it was the only reliable way to measure the distance on the map. You can feel the spirit of those times when you assemble your own curvimeter and put it to good use!
Although the first person to patent the device was Edward Russel Morris (in 1873), the issue of who the original invention belongs to is still viewed differently by various nations. Some attribute it to the prominent Russian mathematician Mykhailo Lomonosov, others claim that Zhāng Héng of the Chinese empire was the one. Certain sources suggest yet another locale – Rome – and a much earlier date of 23 BC, when a certain Virtuvius, an engineer by trade, mentioned a device greatly resembling its later versions.
