Introducing – Tools for Cinema Quality Assurance

Cinema Test Tools for the non-Technical Manager – Post Installation Quality Assurance Has Begun

Cinema Test Tools is a free resource for the cinema industry, tuned most particularly for the non-technical manager. The tools include several DCPs, all with interesting means of testing the sound and picture quality for the interested by lightly trained staff. The lessons on sound and light are written to provide a foundation to communicate with the technician who must respond quickly and well to the information that they discover.

The key is a free Managers Walk Through Checklist that correlates with the many DCPs. It helps bring an understanding of the many nuances of the auditorium's situation in a straightforward way. 

Since we became our own secretaries, it seems that we have to know nearly everything these days.

Manipulating Light On A Chip For Quantum Technologies

Completely useless Pretend Photon PictureA team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light — photons — on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements.

The Bristol Centre for Quantum Photonics has demonstrated precise control of four photons using a microscopic metal electrode lithographically patterned onto a silicon chip.

The photons propagate in silica waveguides — much like in optical fibres — patterned on a silicon chip, and are manipulated with the electrode, resulting in a high-performance miniaturized device.

“We have been able to generate and manipulate entangled states of photons on a silicon chip” said PhD student, Jonathan Matthews, who together with Alberto Politi performed the experiments. “These entangled states are responsible for famously ‘weird’ behaviour arising in quantum mechanics, but are also at the heart of powerful quantum technologies.”

Wind Basics

What a find~! All that we ever wanted to know about the basics of wind, and wind as energy.

We'll only quote the first few paragraphs, and naturally, give the links:

  • Danish Wind Industry Association Site


  • The Power of the Wind: Cube of Wind Speed
  • The wind speed is extremely important for the amount of energy a wind turbine can convert to electricity: The energy content of the wind varies with the cube (the third power) of the average wind speed, e.g. if the wind speed is twice as high it contains 2 = 2 x 2 x 2 = eight times as much energy.

    Now, why does the energy in the wind vary with the third power of wind speed? Well, from everyday knowledge you may be aware that if you double the speed of a car, it takes four times as much energy to brake it down to a standstill. (Essentially this is Newton's second law of motion).

Swiss Cliff

John Mauldin has an excellent piece this week in his Thoughts From The Frontline series entitled The Swiss Start Their Engines. For those who haven't followed John's weekly writings, he is a conservative of the old school, who holds a pretty consistant view that we are in a Muddle Through clip of time.

We'll quote a few paragraphs, then send you to the site link to make it easy to see the graphs that he has with the essay.
