Double-slit experiment
Videos
In modern physics, the double-slit experiment demonstrates that light and matter can exhibit behavior associated with both classical particles and classical waves. This type of experiment was first de
Same double-slit assembly (0.7 mm between slits); in top image, one slit is closed. In the single-slit image, a diffraction pattern (the faint spots on either side of the main band) forms due to the nonzero width of the slit. This diffraction pattern is also seen in the double-slit image, but with many smaller interference fringes.
Fig. 442 in a 1807 book about Young's lectures with a caption by Young that reads: “the manner in which two portions of coloured light, admitted through two small apertures, produce light and dark stripes or fringes by their interference.”
Schrödinger's cat

In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition. In the thought experiment, a hypothetical cat inside a closed box may be considered to be simultaneous
Double-slit experiment
…Feynman stressed that his formulation is merely a mathematical description, not an attempt to describe a real process that we can measure. Like the Schrödinger's cat thought experiment, the double-slit experiment is often used to highlight the differences and similarities between the various interpretations of quantum…
A life-size cat figure in the garden of Huttenstrasse 9, Zurich, where Erwin Schrödinger lived from 1921 to 1926. Depending on the light conditions, the figure appears to be either a live cat or a dead one.
This drawing by F. Gwynplaine MacIntyre, originally published in Analog magazine, illustrates MacIntyre's science-fiction story "Schrödinger's Cat-Sitter". The cat is depicted simultaneously in front of and behind the impossible trident in an optical illusion.
