Answer: Prohibition period from the early 1920s.
Explanation:
Many examples throughout history have had both positive and negative effects on society. Prohibition is one of the better examples. If alcohol were banned in the United States today, for example, there would be a "boom" of the country's black market. Alcohol would be made illegally and distributed on the black market. A positive response would be a reduction in the rate of violence and crime, given that a certain percentage of crime is linked to alcohol.
The Prohibition Period, however, proved to be a failed experiment in American history. The black market has risen sharply, and certain criminal groups have profited greatly. That profit is at the expense of the state since it is not legal. The ban creates a grey economy which badly affects the regular economy of the state.

Isaac Newton was creative in his use of prisms to show how white light is actually made up of multiple colors.  He used logic in the way he presented his arguments rhetorically in order to convince readers of the correctness of his conclusions.
Newton was not the first to experiment with passing light through prisms to determine how light works.  French philosopher Rene Descartes had done prism experiments of his own.  But Descartes had thought that passing through a prism actually modified the light in order to produce the color spectrum.  Newton correctly understood that when light refracted through the prism, it revealed the range of colors that were naturally in the light.  He then used a second prism, blocking all but one color, to show that a single color passing through a prism was not modified in color. He also showed--by positioning the second prism differently--how the multiple colors of light could be recombined into white light again.
Newton's 1672 paper on light refracting through prisms established his reputation as a scientist.  He continued to study light throughout his scientific career, publishing a larger work in 1704 on <em>Opticks </em>(as they spelled "optics" then).
