Vernacular
The term "vernacular" describes the form of language and communication that the general public and the nonscientific community use. Moreover, it is possible for critical theorists to develop complex examinations and critical theories concerning many everyday topics. According to "Street Smarts and Critical Theory," savvy viewers of sitcoms and TV news, Elvis fans, Trekkies, labor organizers, school teachers as well as the average person on the street can all put together complex and observant social theories that resemble scientific theory.
Scientific Theory
The scientific method has been around at least as long as the ancient Greek temples. Aristotle really got the ball rolling by suggesting that knowledge is continuous and that measurement and observation are the foundations of science. Since the days of Aristotle, the Muslim philosophers Baghdad and Al-Andalus, Galileo, Isaac Newton, Francis Bacon and Charles Darwin have practiced scientific theory. In the 20th century, scientists used scientific theory to explain atomic physics and distant astronomical events.
Evolution
Evolution, as put forth by Charles Darwin, is still a popular discussion topic. Though Darwin's understanding of scientific method is not usually questioned, some of his conclusions have come under much scrutiny by other scientists, as well as many clergy, politicians and commentators. Some of the biggest questions revolve around lack of fossil evidence and no adequate explanation of the origin of life. Nonetheless, Darwin's ideas and the general concept of evolutionary theory provide a fascinating illustration of scientific inquiry being challenged by vernacular theorists.
Disproven Scientific Theories
Over time, a scientist's view of the world may be expanded upon or even replaced by other realms of theoretical thought. Take, for example, Copernicus' heliocentric theory that Earth revolves around the sun. In his day, this idea was considered heresy, yet, today, the sun is widely considered to be the center of the solar system. Sir Isaac Newton's theories of physics were widely accepted until the 20th century, when, a young man named Albert Einstein came along and presented a different view of physical realities that superseded Newton's world.
