The lorentz transformations can be (probably invalidly) derived using simple algebra. The idea is to use the postulate that there is no "right" frame of reference, all are equally valid, to show that there is no contraction in the directions perpindicular to motion. Two equal sized (at rest) rings travel towards each other. If contraction occurs perpindicular to direction of motion, one ring becomes smaller and fits inside the other. That ring is at rest in its frame and sees the other ring as contracting and fitting inside of it. Why is that argument flawed (if it is) in proving that the direction perpindicular to motion doesnt contract and is a simple logical algebraic derivation based on that not mathematically sound even if it produces the correct transformations.

"Oh, no," said the priest, thinking of the most promiscuous women in town. "Was it with Marie Brown?"

"I'd rather not say who it was."

"Was it with Betty Smith?"

"I'd rather not say," says Joe. So the priest gives him absolution and Joe leaves. While
leaving the church, Joe's friend asks if he received absolution.

"Yes, and two very good leads!"
