The Crystal Palace was originally erected in London, England in 1851. The construction system consisted of prefabricated and wrought iron elements along with glass. The palace was based on twenty-foot modules and designed by Joseph Paxton and Charles Fox. The Crystal Palace had extreme significance because it was the first large building constructed of metal and glass. In addition, the Crystal Palace was the first building erected in which the outer walls were not engineered to provide support for the structure. I believe the Crystal Palace's most significant contribution to building was it was the first building to be built pre- fabricated.
             The evolutionary model by Darwin is based on 3 primary functions. First, blind variation. Second, selection process. Third, selective retention. Our design and creativity comes directly from our evolution. As we retain past experiences, products, and ideas we build from them. For example, the stagecoach and its design carrying over into the automobile. The similarities between the two are extremely similar. This is a perfect example of how evolution molded our design of the automobile. As in Darwin's evolutionary model, blind variation plays a part in design and creativity also. For example, the first works that surfaced regarding the creation of the wheel. This invention was of truly blind variation.
             The principle of ceteris paribus applies to all research where the variables are being manipulated (experimental, quasi-experimental) and it also applies to studies where treatment is being controlled. Ceteris paribus means "all things being equal" and involves the procedures we use to control the variance in our study.
             All research is presented with innumerable opportunities for unpredictably varying the conditions in which the research is being performed. Controlling these is a hallmark of quality research. Some variance is to be expected and there's a way to measure these random errors....
