In this review, we place laboratory natural selection in context with other selection experiments, identify the characteristics which make it well suited for particular kinds of applied research and briefly cover key examples of the usefulness of selection experiments within applied science. Finally, we...

In laboratory experiments, it is very difficult to control, as well as identify, all the possible variables that may have an influence on a particular scenario in the past. Positivists see it as possibly unethical to control all of the variables within laboratory experiments as most of the ...
Give two advantages and two disadvantages of quasi-experimental designs. What are the strengths of correlation research, observational/descriptive research, and experiments? What are the different types of quantitative research methods? What is the difference...
The Hall effect has a history of over a hundred years, but it has not been significantly applied until the last thirty years. The first practical application (outside of laboratory experiments) was as a microwave power sensor in the 1950s. With the large-scale production of semiconductors, th...
Despite being applied with success in many fields of materials science, Raman spectroscopy is not yet determinant in the study of electroceramics. Recent experimental and theoretical developments, however, should increase the popularity of Raman spectros

He developed an interest in physics and mathematics from the early days of his education. With no laboratory available in school and college, he would perform experiments in his father's laboratory. His first work on surface tension was done here,for which he won the Gold Medal in 1906 from...
