Do we need 48 fps?  

The answer isn’t as simple as it might seem.

For example:

“Imagine yourself in a very dark room. You have been there for hours and it’s totally black. Now light flashes right in front of you. Let’s say as bright as the sun. Would you see it, when it’s only 1/25th of a second? You surely would. 1/100th of a second? Yes. 1/200th of a second? Yes. Tests with Air force pilots have shown, that they could identify the plane on a flashed picture that was flashed only for 1/220th of a second.”

From 100fps.com: How many frames per second can the human eye see?

Werner Herzog

From a letter to Werner Herzog by Roger Ebert:

It is safe to say you are as admired and venerated as any filmmaker alive—among those who have heard of you, of course. Those who do not know your work, and the work of your comrades in the independent film world, are missing experiences that might shake and inspire them.

Unobtanium


This is a photo of a real piece of metal that has been cooled to the point that it has become a superconductor. In the movie Avatar they say that Unobtanium is a room temperature superconductor. The unobtanium article on Wikipedia.
