To those of a physics or engineering bent, the name Nikola Tesla is a well-known and illustrious one. To even attempt to provide a biography of the man within the confines of this humble blog would be to do him an injustice, so I will leave it to you, dear reader, to find out more about him should you so wish.
Suffice to say that, as this story proves, he was a man ahead of his time. Like so many scientists and writers of the period, such as Thomas Edison, H. G. Wells and Jules Verne, they postulated machines and ideas that were totally beyond the technology that was only just becoming available then. This is the mark of a true inventor - the ability to see beyond what is currently possible and to create new technologies that move things on to the next level.
At a time when wireless telegraphy was at its height, and the telephone a relatively new invention, Tesla was already looking ahead to the next stage. Whether he could have foreseen the debilitating dependency many people have nowadays on these Blackberrys and similar devices, or the other adverse effects on society that these machines often engender, is another matter. From a scientific point of view, however, Mr Tesla's prediction is worthy of high comment.
