After the introduction of the cinématographe, it took over 10 years before animated films returned to the theatres (with Humorous Phases of Funny Faces (1906) by J. Stuart Blackton). The animated segment in Winsor McCay's Little Nemo (1911) was probably the first animation to use more hand-drawn images than the 700 images of Reynaud's Un Bon ...
The year after Ross's expedition, in 1819, Parry was given command of his own Arctic expedition, and proved Ross wrong by continuing west beyond where Ross had turned back, and sailing through the supposed location of the Croker Mountains. The mountain range that had caused Ross to abandon his mission had been a mirage. Ross made two errors.
Schmidt–Cassegrain telescopes are one of the most popular commercial designs on the amateur astronomical market, [6] having been mass-produced since the 1960s. The design replaces the Schmidt Camera film holder with a Cassegrain secondary mirror, making a folded optical path with a long focal length and a narrow field of view.

The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...
