My colleague took his son of 7 years old to work. This is a realy nice kid, so once and a while this is fine.
I showed my colleague my new eXplorist. He was enthusiastic and of course the boy wanted to know why we were enthusiastic like that.
I did explain him that this gps device got the signal of at least 3/4 gps satellites and that they that were telling it where they are. By knowing that the device can make an calculation to know where it is itself…anywhere on the globe. This is the elementary version.
You could have talked about atomic clocks and the delay of the signal, but this is for an older age I would say.
I really like to explain things to others, I must be the trainer in me… But it is extra nice to explain things to kids(, especially if it is one of your favourite subjects). They are often so inquisitive.
I know, not all of them!
