We see things as solids because of our limits of observation. In reality, everything physical exists in a wave like state. Until we “collect” a particle from a fixed point, they exist in a wavelike form and function in a wavelike manner.
We only need a frame speed of 24fps to produce the illusion of continuity of motion.
When sound film was first introduced in 1926, variations in film speed were no longer tolerated as the human ear was more sensitive to changes in audio frequency. From 1927 to 1930, the rate of 24 FPS became standardized for 35 mm sound film; a speed of 456 millimetres (18.0 in) per second. This allowed for simple two-blade shutters to give a projected series of images at 48 per second. Many modern 35 mm film projectors use three-blade shutters to give 72 images per second—each frame flashed on screen three times.
But here comes,
Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look “around” corners or see inside the body without X-rays.
Seems to me this is similar to an electron microscope, but of moving objects.
