I want to inaugurate my new category "Wireless Life" with this quotation of Albert Einstein describing the radio :
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.
