#The barn and ladder paradox: Person A has a ladder too long to store in his barn. Person B takes the ladder and runs very fast into the barn. For A, who is at rest with respect to the ladder, the ladder will contract, and if the velocity is fast enough, it will fit in the barn. But to B, who is moving with the ladder, it is the barn that will contract, making the problem even worse. So, who is correct? Does the ladder fit in the barn? This problem was considered in the book Introduction to Electrodynamics by David Griffiths, and the author, who supports Relativity, claim that both are correct. The ladder both fit and doesn’t fit in the barn. This is obviously against elementary rules of logic.

#Spin is an effect introduced by relativity into quantum mechanics. Spin stands for a rotation of electrons, but that rotation makes the surface of the electron move faster than the speed of light, which is prohibited by relativity itself.
