The name 'Mount Everest' was named when Sir George Everest, the surveyor general of India from scaled the peak in1856. It was called Peak XV until before 1856. The height measurement of the peak was done through the Great Trigonometrically Survey in 1850. Nepali name of the Mt. Everest is 'Sagarmatha', meaning "Sky Mother." However, the Tibetan people love to call it 'Chomolungma', which refer to "Mother Goddess of the Country."
There is a great controversy regarding the exact height of Mount Everest. Andrew Waugh, the successor of George Everest had given its height 29,002ft (8842m. Later, this height was increased to 29,028ft (8,848m) which is the universally accepted altitude. In 1999, the Boston Museum of Science GPS system attached to Bishop's Ledge, the outcrop just below the summit, suggested the height no more than 8,830m (28,970ft). Similarly, the National Geographic Society announced that the correct height of the Everest was 8,850m (29,035ft). Let the geologists go on exploring the actual height of the Everest; it is anyhow, the highest mountain in the world. It is reported that the mountain is rising a few millimeters each year due to geological forces.
