## Main Question or Discussion Point

Dear forum members,

My 10 year old son intuitively figured out the concept of frames of reference. After a series of questions regarding walking down the aisle of an aircraft at x mph and how that would appear to a fellow passenger versus someone on the ground, he startled me by asking whether the photons emerging from the flashlight shone by the passenger on the plane would seem to move at 300,000 km/sec plus the speed of the plane to a terrestrial observer.

I would like to explain special relativity to him but need some help with analogies that would get the key concepts across without delving into the math (he is working on basic algebra but clearly not ready for anything serious).

Are there any books that would help me articulate in simple terms the concepts of special relativity? It does not have to be something he can read - it is more for me to read and give me ideas to communicate to him.

Any help would be appreciated.

Thanks!
