I've been studying for a test in Wireless Communications when I came across this quote I liked by Albert Einstein:
"You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat."
Doesn't that just make perfect sense?
