Ever since the Sonic Screwdriver first appeared in Fury From The Deep , it has fascinated viewers. Starting off as a futuristic way to remove a screw it progressed and gained additional functionalities over the years. The Second Doctor used it to screw/unscrew screws, burn through a door, and hack a computer. The Second Doctor used the screwdriver a total of seven times during his three year tenure , and it was viewed as just one of many contraptions the Doctor used.
Future Doctors, with some exceptions, used more of the ever-increasing functions of the screwdriver to save the world, the galaxy, or even the universe—much to the chagrin of many a viewer who take polarising views of the little device. Some people refer to it as the Doctor’s Gallifreyian Army Knife, yet other complain it’s nothing more than a deus ex machina.
Since 1967 it has gone from being a curious tool the Doctor occasionally pulled to a device that is constantly in his hands. In the 50th year of the Doctor, it seems odd to see the Doctor without the screwdriver in his hand.
But this is not an article to discuss whether the screwdriver is overused or not. I am here to explain, in real world acoustic sciences, how the sonic screwdriver could possible do what it does. Not every function will be explained as that would create n article far too long. Instead I will cover the acoustic basics of the better known uses.
