Are we heading towards a controlled society?

One of our latest arrivals.

Are we heading towards a controlled society?

Old news perhaps but I checked out the word Terahertz and it is part of the Spectrum.

(1984 could be upon us sooner rather than later)

I wouldn't worry about em radiation in the terahertz range. Research is looking at applications of this part of the spectrum and this is no more sinister than any other applications

From Wikipedia http://en.wikipedia.org/wiki/Terahertz_radiation

Research

• Medical imaging:
  • Unlike X-rays, terahertz radiation has a relatively low photon energy for damaging tissues and DNA. Some frequencies of terahertz radiation can penetrate several millimeters of tissue with low water content (e.g., fatty tissue) and reflect back. Terahertz radiation can also detect differences in water content and density of a tissue. Such methods could allow effective detection of epithelial cancer with an imaging system that is safe, non-invasive, and painless.
  • Some frequencies of terahertz radiation can be used for 3D imaging of teeth and may be more accurate than conventional X-ray imaging in dentistry.
• Security:
  • Terahertz radiation can penetrate fabrics and plastics, so it can be used in surveillance, such as security screening, to uncover concealed weapons on a person, remotely. This is of particular interest because many materials of interest have unique spectral "fingerprints" in the terahertz range. This offers the possibility to combine spectral identification with imaging. Passive detection of terahertz signatures avoid the bodily privacy concerns of other detection by being targeted to a very specific range of materials and objects.[SUP][12][/SUP][SUP][13][/SUP] In January 2013, the NYPD announced plans to experiment with the newfound technology to detect concealed weapons,[SUP][14][/SUP] prompting Miami blogger and privacy activist Jonathan Corbett to file a lawsuit against the department in Manhattan federal court that same month, challenging such use: "For thousands of years, humans have used clothing to protect their modesty and have quite reasonably held the expectation of privacy for anything inside of their clothing, since no human is able to see through them." He seeks a court order to prohibit using the technology without reasonable suspicion or probable cause.[SUP][15][/SUP]
• Scientific use and imaging:
  • Spectroscopy in terahertz radiation could provide novel information in chemistry and biochemistry.
  • Recently developed methods of THz time-domain spectroscopy (THz TDS) and THz tomography have been shown to be able to perform measurements on, and obtain images of, samples that are opaque in the visible and near-infrared regions of the spectrum. The utility of THz-TDS is limited when the sample is very thin, or has a low absorbance, since it is very difficult to distinguish changes in the THz pulse caused by the sample from those caused by long-term fluctuations in the driving laser source or experiment. However, THz-TDS produces radiation that is both coherent and spectrally broad, so such images can contain far more information than a conventional image formed with a single-frequency source.
  • Submillimeter waves are used in physics to study materials in high magnetic fields, since at high fields (over about 11 tesla), the electron spin Larmor frequencies are in the submillimeter band. Many high-magnetic field laboratories perform these high-frequency EPR experiments, such as the National High Magnetic Field Laboratory (NHMFL) in Florida.
  • Submillimetre astronomy.
  • Terahertz radiation could let art historians see murals hidden beneath coats of plaster or paint in centuries-old buildings, without harming the artwork.[SUP][16][/SUP]
• Communication:
  • Potential uses exist in high-altitude telecommunications, above altitudes where water vapor causes signal absorption: aircraft to satellite, or satellite to satellite.[SUP][citation needed][/SUP]
• Manufacturing:
  • Many possible uses of terahertz sensing and imaging are proposed in manufacturing, quality control, and process monitoring. These in general exploit the traits of plastics and cardboard being transparent to terahertz radiation, making it possible to inspect packaged goods.

It sounds all good to me but I gather the paranoia is about the potential for remote scanning for security reasons. I find this no more threatening than using infrared devices to detect fugitives at night or to locate people buried under rubble.

The tone seems a trifle 'shrill' to me but I'll read a few other of their articles out of interest to see which tack they're on.
It all sounds too sci-fi to me, emotions yes, but actual logical thoughts? What language do they read them in? Does it have a spellchecker?

What language do people born deaf think in?? Do they have translators on duty? What if it was a Koori who like one I read of lately was the last person on earth who could still speak their original tribal language? How would they know what someone was thinking then??
