The ultimate cause of much historical, social and cultural change is the gradual accumulation of human knowledge of the environment. Human beings use the materials in their environment to meet their needs and increased human knowledge of the environment enables human needs to be met in a more efficient manner. The human environment has a…[Read more]

This paper reviews some of the literature on the philosophy of quantum mechanics. The publications involved tend to follow similar patterns of first identifying the mysteries, puzzles or paradoxes of the quantum world, and then discussing the existing interpretations of these matters, before the authors produce their own interpretations, or side…[Read more]

This paper addresses the question of whether the fetus is human and its effect on the abortion debate. It investigates the concept of “human” and asks whether the concept of human has an essence or is best understood by the idea of family resemblance. It asks whether DNA is the essence of humanity and concludes that it is not and that humanity is…[Read more]

Organic chemistry in the nineteenth century developed with a specific order of discovery, which was the inevitable path by which our knowledge of organic chemistry had to develop. New methods of analysis of organic materials led to new experimental results, which led to new theories about the nature of organic chemistry. Some of those theories…[Read more]

The ultimate cause of much historical, social and cultural change is the gradual accumulation of human knowledge of the environment. Human beings use the materials in their environment to meet their needs and increased human knowledge of the environment enables human needs to be met in a more efficient manner. When human knowledge of the…[Read more]

The ultimate cause of much historical, social and cultural change is the gradual accumulation of knowledge of the human environment. The invention of glass and microscopes and telescopes, substantially increased human knowledge of the human environment. Microscopes and telescopes would not have been possible without the prior discovery of…[Read more]

The invention of photography was only possible due to the camera obscura effect which produces an upside down image of a scene on the back wall of a box when light is reflected through a tiny hole in the box. The camera obscura effect has been known since classical times. The invention of photography required that the image be fixed and…[Read more]

The invention of motion pictures was only possible due to the prior discovery of the phenomenon of persistence of vision, the prior invention of photography and the ability to produce photographs with very brief exposure times. These discoveries were necessary before motion pictures could be invented, and given how human beings like to be…[Read more]

This paper was written in order to study the development of stone tool technology throughout the Paleolithic. It finds the technology developed, with the simplest discoveries being made first and more complex discoveries being made later. The chemical structure and the properties of the raw materials determined that stone tools could be useful to…[Read more]
