This lecture is about a new method that helps to recalculate the elevation of Mountain Everest. A team of scientists used the Global Positioning System, which relied on advanced technology, to figure out that the peak’s actual height is higher than the previous value. In fact, the lighter receiver was easier for climbers to carry to the summit. Finally, satellites provided a more precise elevation through transmitting signals.
