Another reason Lippmann's process of colour photography did not succeed can be found in the invention of the autochrome plates by the Lumière brothers. [1] A technique derived from the Lippmann technique has been proposed as a method of producing images which can easily be viewed, but not copied, for security purposes.
Umklapp scattering is one process limiting the thermal conductivity in crystalline materials, the others being phonon scattering on crystal defects and at the surface of the sample. The left panel of Figure 1 schematically shows the possible scattering processes of two incoming phonons with wave-vectors ( k -vectors) k 1 and k 2 (red) creating ...
Additionally the direction of motion can reverse due to the existence of multiple 3D visual solutions. Leaning tower illusion: The Leaning tower illusion is an optical illusion that presents two identical images of the Leaning Tower of Pisa side by side. Lilac chaser: Lilac chaser is a visual illusion, also known as the Pac-Man illusion.
Magic moving pictures were composed of images containing black vertical and regularly interlaced stripes, alternating between two or three phases of a depicted motion or between distinctly different pictures. A little transparent sheet with regular vertical black stripes was glued beneath a window in a cardboard envelope holding the picture card.
Ghost imaging (also called "coincidence imaging", "two-photon imaging" or "correlated-photon imaging") is a technique that produces an image of an object by combining information from two light detectors: a conventional, multi-pixel detector that does not view the object, and a single-pixel (bucket) detector that does view the object.

Thus, heat is motion at the atomic and molecular levels. The primary mode of motion in crystalline substances is vibration. Any given atom will vibrate around some mean or average position within a crystalline structure, surrounded by its nearest neighbors. This vibration in two dimensions is equivalent to the oscillation of a clock
