The mammalian jaw joint is composed of different skull bones, including the dentary (the lower jaw bone which carries the teeth) and the squamosal (another small skull bone). In mammals, the quadrate and articular bones have evolved into the incus and malleus bones in the middle ear. [20] [21]
The essential idea is that behavior can be modified by its consequences, as Thorndike found in his famous experiments with hungry cats in puzzle boxes. The cat was placed in a box that could be opened if the cat pressed a lever or pulled a loop. Thorndike noted the amount of time it took the cat to free itself on successive trials in the box.
During Beethoven's autopsy, pathologist Johann Wagner [12] sawed Beethoven's skull open and cut out his temporal bones. When his body was exhumed in 1863, the temporal bones and six of his teeth were missing. His skull was in nine pieces. Some fragments were taken before the body was reinterred. They were later found to be held by Franz Romeo ...
Original puzzle box designed by Edward Thorndike. In 1898, American psychologist, Edward Thorndike proposed the 'law of effect', which formed the basis of operant conditioning. [8] Thorndike conducted experiments to discover how cats learn new behaviors. His work involved monitoring cats as they attempted to escape from puzzle boxes.
Schrödinger's cat: a cat, a flask of poison, and a radioactive source connected to a Geiger counter are placed in a sealed box. As illustrated, the quantum description uses a superposition of an alive cat and one that has died. In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition.
The name describes the pattern of infolding of the dentin and enamel of the teeth, which are often the only part of the creatures that fossilize. They are also distinguished by a broad, strongly-built skull roof composed of many small heavily-textured skull bones.
The cat skull is unusual among mammals in having very large eye sockets and a powerful and specialized jaw. [28]: 35 Compared to other felines, domestic cats have narrowly spaced canine teeth, adapted to their preferred prey of small rodents. [29]
English: The Kennedy-Thorndike experiment. Key optical components were mounted within vacuum chamber V on a fused quartz base of extremely low coefficient of thermal expansion. A water jacket W kept the temperature regulated to within 0.001°C.
