From Bacteria to Bach and Back: The Evolution of Minds is a 2017 book about the origin of human consciousness by the philosopher Daniel Dennett, in which the author makes a case for a materialist theory of mind, [1] arguing that consciousness is no more mysterious than gravity.
Gravitational biology is the study of the effects gravity has on living organisms. Throughout the history of the Earth life has evolved to survive changing conditions, such as changes in the climate and habitat. However, one constant factor in evolution since life first began on Earth is the force of gravity.
In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as a mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force, and 10 29 times weaker than the weak interaction.
He rejects the idea that because the mind is not objectively viewable, it does not fall under the rubric of physics. Searle believes that consciousness "is a real part of the real world and it cannot be eliminated in favor of, or reduced to, something else" [1] whether that something else is a neurological state of the brain or a computer program.
The theory posits that the human mind once operated in a state in which cognitive functions were divided between one part of the brain that appears to be "speaking" and a second part that listens and obeys—a bicameral mind—and that the breakdown of this division gave rise to consciousness in humans.
[99] [100] However the theory of gravity itself was not accepted quickly. The theory of gravity faced two barriers. First scientists like Gottfried Wilhelm Leibniz complained that it relied on action at a distance, that the mechanism of gravity was "invisible, intangible, and not mechanical".
In theoretical physics, particularly in discussions of gravitation theories, Mach's principle (or Mach's conjecture [1]) is the name given by Albert Einstein to an imprecise hypothesis often credited to the physicist and philosopher Ernst Mach.
Hypergravity is defined as the condition where the force of gravity (real or perceived) exceeds that on the surface of the Earth. [1] This is expressed as being greater than 1 g . Hypergravity conditions are created on Earth for research on human physiology in aerial combat and space flight, as well as testing of materials and equipment for ...
