EINSTEIN BONUS: Go Geo-caching around Cedar City.
In our unit on Einstein and relativity, we are learning how modern day GPS uses the theory of relativity because gravity curves space and time which results in orbiting clocks ticking slightly faster on Earth.
“General relativity predicts that time will appear to run slow under stronger gravitational pull which means the clocks on board the satellites will therefore seem to run faster than a clock on Earth. Furthermore, special relativity predicts that because the satellites’ clocks are moving relative to a clock on Earth, they will appear to run slower. The whole GPS network has to make allowances for these effects.” ~Physics.org
Yay for cool science! So go with your family and teach them about all you are learning in class.
