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 playful analogy describing the functioning of wire telegraph and radio signals. It suggests that wire telegraph works like a long cat - pulling its tail in one place causes a reaction or a response in another place, just like pulling a cat's tail in New York makes its head meow in Los Angeles. Similarly, radio signals operate in a similar manner by sending signals from one place to receive them in another, but without the presence of a physical cat. The quote uses humor to simplify the concept of how communication signals travel through wire telegraph and radio technology.
