Wireless Telegraphy and Telephony Popularly Explained By Walter Wentworth Massie, Charles Reginald Underhill, Nikola Tesla: "A mass in movement resists change of direction. So does the world oppose a new idea. It takes time to wake up the minds to its value and importance. Ignorance, prejudice and inertia of the old retard its early progress. It is discredited by insincere exponents and selfish exploiters. It is attacked and condemned by its enemies. Eventually, though, all barriers are thrown down and it spreads like fire."
The above quote was given by Tesla in 1909, though I feel it is timeless. Google Books has papers and patents written by Tesla, the greatest electrical engineer of all time.
