Dr. Who's Sonic Screwdriver a Step Closer To Reality 94

Posted by samzenpus from the daleks-are-coming dept.
cylonlover writes "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. The team of physicists at the University of Dundee in Scotland (with associates at Bristol University in England) have succeeded in generating an ultrasonic vortex beam strong enough to lift and rotate a rubber disk submerged in water. 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." We covered the beginning of the sonic screwdriver project by Bristol University engineers a little over a year ago.

      It was a magic wand in the old series too, after a time. That's exactly why it got written out after a while, resulting in the Fifth Doctor going "hands free", as Tenant put it.

      That is always a problem with Science Fiction. You have a writing paradox where the man from the future/advanced race. Has technology far exceeding our normal understanding, however if you use such technology you are using techno-babble to solve your plots.

      Lets say you have a Multi-Tool and you are thrown back to the Stone age Cave man. In their mindset your Multi-tool may not seem like a threatening object, small leather pouch. Compared to the Large clubs, and spears with sharp (largish) arrow heads this collapsed multi-tool may not seem like a threat, and say you are locked into a wooden cage. You could just use the saw attachment to cut the wood and your free. If this was a stone age science fiction it would be like you multi-tool has a tool for every situation.

        It's not really a problem: you establish upfront the kinds of things it can and can't do, and stick by that. That's exactly what distinguishes Science Fiction form Science Fantasy (and the flipside, whatever they call it: stories where magic has well-defined rules).

      It's disappointing the way the writers abuse it, but to be fair, if you had any piece of technology and upgraded it continuously for a few hundred years, it would like magic compared to the original version.

      Kind of like a modern cell phone that is a phone/personal computer/camera/video camera/GPS system and calling it a quill because that was what you originally had in the 15th century when you started..

  • In the series the screwdriver can do just about anything as long as it's not wood that it's working on (or some biological stuff). The good Doctor uses it to do just about everything. I seriously doubt we have the ability to create a magical device that can by pointing at a computer made by an alien species do what we want.

      This is a case of feature creep.

      In Fury from the Deep it was used to open things--exactly how you'd expect a futuristic, but single purpose, device to work. He uses it to weld in the Dominators, which is the start of it getting extra properties. The War Games again uses it to open things, but it became an out of control plot device soon after that.

      That's why they destroyed it in the Visitation. The new series brought it back and it seemed to have been an out of control plot device from the very start.

        As much as they want to call it "Sci Fi," Doctor Who is fantasy, and the sonic screwdriver is nothing short of a magic wand.

        The whole of Series 5 should have clinched that for anyone paying attention. In order to save the universe, the Doctor had to reboot it, requiring him to cease to exist, although he could be brought back as soon as Amy remembered him? It was even openly admitted that it was a Fairy Tail. This isn't sci fi. As soon as you let go of that, you can start to enjoy it again, like pure fa

    • In case you haven't noticed, most science fiction TV is really fantasy fiction.

      The things they do on shows like Who and Star Trek and Stargate are impossible in the real world, just like Harry Potter is impossible. The only show that could be called Science fiction is Babylon 5, though it too made some errors (the whitestar measured -400 celsius temperature on Jupiter). It's hard to make real honest-to-goodness science-based stories, especially on a TV schedule with one episode filmed every 10 days.

      • That's because they're not really supposed to be science based. Any good science fiction is about the people involved, not the technology. The tech is just a backdrop.

        • The technology may be the backdrop but it's supposed to be realistic. Imagine a science fiction story set in the present, and it had Americans simply teleporting themselves to work by saying, "I want to go to work." That's not science; that's not reality or even possible. It's fantasy fiction.

              Stupidest comment of the week. There's a lot of science fiction set in the present, or even some in the past (such as explaining how Jack the Ripper was actually an alien doing a brief Earth visit/experiment).

              The thing that separates *science* fiction from *fantasy* fiction is that the first can happen in the real world, while the second can not. This is self-evident in the very naming of each genre.

    Sorry, I'm going to be a little pedantic here, but the sonic screwdriver doesn't really have any set of capabilities to emulate. Something like the tricorder at least has some vague definition-- it's a set of sensors that can tell you about the material composition and structure of items at a distance.

    But the sonic screwdriver? How the device works is something like, "point it at anything in order to get the writers out of the corner they've painted themselves into". There's nothing that it can not do, except apparently that it doesn't work on wood. How are you going to build that, and how will you know when you've succeeded?

      It's called a plot device [wikipedia.org] in the industry.

      Reality isn't one of it's strong points.

    • Implying the the Name of the Device does not contain any form of description encoded in it's meaning.
      IMHO, "Sonic Screwdriver" is far more descriptive of the device's workings and operation than "Tricorder" is.

      But please, don't let me dissuade you from thinking that they are working feverishly to make a device that does everything that it's fictional TV Show counterpart did.

    • Personally, I've been wanting a good electric screwdriver for a long time, and I wish someone would invent such a device. There've been many lame attempts at making electric screwdrivers over the past 10-20 years, but they've all sucked: they're huge and heavy, and turn incredibly slowly, and have little torque. I want something that's no bigger than my little ratcheting screwdriver (fits in my hand), has variable speed controllable by pressure, and can turn as fast as an air impact wrench can zip off lug

    • You could ask your eardrums how well moving things with sound works in a less dense fluid...

      I suspect that the mathematical trickery required to get sound waves to push an object in a concerted way, rather than just bouncing around chaotically, was a fair trick; but (normally trivial) moving things is what makes sound sound like sound.

The new series has some Star Trek nerd BS that rubbed off on it where they feel the need to explain more detailed BS while in the old shows they rarely went into any more detail than necessary to the story. They were/are also more realistic in the sense that some expert (in a hurry) describes things to laymen in a simple metaphorical summation.
