Quote 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.
Summary
This quote is a whimsical way of explaining how telegraph and radio communication work. It likens a wire telegraph to a long cat, where pulling its tail in New York (sending a signal) results in its head meowing in Los Angeles (receiving the signal). Similarly, radio operates similarly, transmitting signals from one place and receiving them at another location. The difference, of course, is that telegraph and radio don't involve an actual cat; it simply highlights the concept of distant communication.
