Dr. Who’s Sonic Screwdriver For Real!
When I asked him what this thing is supposed to do he said “everything”. Except of course control wood.
A University of Dundee research team led by Prof. Mike MacDonald has demonstrated that both levitation and twisting forces can be applied to an object by application of ultrasonic beams. This latest breakthrough is part of a wide-ranging U.K. research effort to develop a device not unlike the “sonic screwdriver” made famous by the TV series Doctor Who.
The sonic screwdriver has been a favored tool of ten Doctors at this point in time (it was introduced by the second Doctor). It has evolved from a simple screwdriver and lock-pick to include such functions as repairing electronics, remotely controlling the Tardis, amplifying X-rays, and even converting a cellphone to truly universal roaming. Without the screwdriver, Earth would have fallen countless times to Daleks, Cybermen or Silurians.
