It was a book from 1970s or 1980s about physics written in a popular informal way. It described relative motion by example of shooting an arrow from the back of a train, it described the Michelson-Morley experiment and it contained a quote from Lewis Carroll.
But I was thinking of a plan
To dye one's whiskers green,
And always use so large a fan
That they could not be seen.
Can you help me identify the book?

Additional info: I think that it also contained a description about two lightbulbs inside a closed box and that the two lightbulbs are turned on, then the question is whether or not there will be a shadow from any of the lightbulbs.
I think I remember that the cover was white and green and that it was quite easy reading and popular science because I could understand it even though I did not know calculus at the time but it did explain relativity with words and examples instead of mathematical equations.
