Taylor and McDonald's coordinated to block independent diagnostic tools, preserving a lucrative repair monopoly rather than deploying secret self-destruct code. More

How Einstein's Theory of Relativity Prevents Your Phone's GPS From Drifting Miles Off Course Every Day

GPS satellites run on atomic clocks that tick faster than identical clocks on the ground. Weak gravity in orbit speeds them up, while their orbital speed slows them down, leaving a net gain of roughly 38 microseconds every day. Without compensating for Einstein's theories of relativity, navigation apps would drift by about 10 kilometres every 24 hours. More
