Einstein And Google Map
We all know Albert Einstein, German born physicist who developed the special and general theories of relativity and won the Nobel prize for Physics on 1921 for the explanation of photo electric effect. Do you know He also contributed indirectly on Google Maps!? Yes, Albert Einstein's theories of relativity, formulated in the early 20th century, had a huge impact on our understanding of the universe. One of the most unexpected applications of his theory is Global Positioning System.
According to special relativity , time appears to move differently for observers who are in relative motion. The GPS satellites are prone to time dilation effects because of their high orbital speed of 14,000 kilometres per hour. Because of their relative velocity, the clocks aboard GPS satellites tick somewhat faster than the clocks on Earth's surface. If this impact were not taken into account, the timing gap between the satellites and receivers would compound over time and cause a severe decline in GPS accuracy.
General relativity predicts that clocks in stronger gravitational fields run slower than clocks in weaker gravitational fields. Since GPS satellites are farther from the Earth's centre, they experience weaker gravity compared to clocks on the Earth's surface. This gravitational time dilation effect causes clocks on GPS satellites to tick faster relative to clocks on the ground. Without corrections for this effect, GPS position accuracy would also degrade over time.
