Answer 2

I assume by this you mean Einstein's relativity, right? Because relativity in general has been around for a long, long time.

Answer 3

relativity plays a key role in a multi-billion dollar growth industry centered around the Global Positioning System (GPS)....

Answer 4

GPS is the classic example. You might explore this by thinking of the ways in which GPS influences your day-to-day life, or you might try something completely different. Relativity is the theoretical grounding of the electromagnetic doppler shift phenomenon, which allows police officers to pull you over for speeding with their radar guns, for instance. Einstein and his damnable science...

Answer 5

@jemurray, actually that's not right. The doppler effect was observed and quantified in the 19th C, well before relativity (special or general).

Answer 6

The theory developed in the 19th Century predated special relativity but did not correctly describe the apparent shift in the spectrum of electromagnetic radiation because it demanded a medium through which the waves were to travel. When the time-dilation effect and the lack of a physical medium are included, you obtain the correct relation for light, but this wasn't until later.

Answer 7

At least as far as I know, I suppose...
