In a flight from Minneapolis to Memphis, Tim Wildmon, the President of American Family Radio (AFR), was perplexed because the blue dot on Maps, displayed on his iPad, was following the flight he was on, and he was not even connected to the Internet. On his radio program, Wildmon asked how this was happening.
A retired Merchant Naval officer telephoned to give the answer. The Global Positioning System (GPS), according to the caller, does not use the Internet. It is a system of twenty-four or more active data satellites that are in earth’s orbit. A cell phone or iPad has a receiver inside which receives the signals. The computer in the cell phone will compute the angular differences and find your position. This information will provide your direction, your velocity, and altitude. This is the same system that works from the GPS in cars.
It’s easy to assume that everything is dependent on the Internet; this anecdote illustrates that not everything is.

Let’s see how you’re doing.

It’s easy to assume that everything is dependent on the Internet; this anecdote illustrates that not everything is. The preceding statement qualifies for an antithesis (an-TITH-uh-sis), which puts two opposing statements together to make a point. My favorite antithesis came from the beloved John F. Kennedy: “Ask not what your country can do for you; ask what you can do for your country.”
