In conclusion, while the Cannon-Washburn experiment provided a crucial starting point for the scientific study of hunger, modern research has revealed a far more complex picture. The integration of hormonal, neural, microbial, cognitive, and environmental factors into our understanding of hunger and appetite regulation represents a significant ...
Walter Cannon began his career in science as a Harvard undergraduate in the year 1892. Henry Pickering Bowditch, who had worked with Claude Bernard, directed the laboratory in physiology at Harvard. Here Cannon began his research: he used the newly discovered x-rays to study the mechanism of swallowing and the motility of the stomach.
Washburn's equation is also used commonly to determine the contact angle of a liquid to a powder using a force tensiometer. [ 5 ] In the case of porous materials, many issues have been raised both about the physical meaning of the calculated pore radius r {\displaystyle r} [ 6 ] and the real possibility to use this equation for the calculation ...

The term sham rage was in use by Walter Bradford Cannon and Sydney William Britton as early as 1925. [3] Cannon and Britton did research on emotional expression resulting from action of subcortical areas. Cats had their neocortices removed but still displayed characteristics of extreme anger resulting from mild stimuli. [4]
Cannon summarises the observations that serve as the basis for his theory of emotion which claims the thalamic region is the coordinating center for emotional reactions. [14] First, after the removal of the cerebrum anterior to the thalamus in animal test subjects, the animals continue to display rage-like emotional responses.
However, when a cannonball was fired at a wooden wall, the splinters did not have enough power to pierce any of the pigs. To fully confirm or bust the myth, the MythBusters used an authentic Civil War-era cannon. Through preliminary testing, they proved the Civil War cannon was significantly more powerful than the air cannon.
An analysis and criticism of theomatics has been published by Tim Hayes, previously under the pseudonym "A. B. Leever". [3] [4]A German statistician, Kurt Fettelschoss, published an analysis [5] that claims that "The observed quantity of theomatic hits is significantly not random". [6]
