In scientific research, an experiment ( Latin ex- periri, "to try out") is a method of investigating causal relationships among variables, or to test a hypothesis. An experiment is a cornerstone of the empirical approach to acquiring data about the world and is used in both natural sciences and social sciences. An experiment can be used to help solve practical problems and to support or negate theoretical assumptions. 'Controlled experiments' Many people in science such as scientist can do an experiment or test something by using the scientific method.The steps are make an observation, ask a question, form a hypothesis, test the hypothesis, analyze the results, draw a conclusion, and comunicate results. The reason you test a hypothesis is so you can prove your question 100% right or wrong. An example that is often used in teaching laboratories is a controlled protein assay. Students might be given a fluid sample containing an unknown (to the student) amount of protein. It is their job to correctly perform a controlled experiment in which they determine the concentration of protein in fluid sample (usually called the "unknown sample"). The teaching lab would be equipped with a protein standard solution with a known protein concentration. Students could make several positive control samples containing various dilutions of the protein standard. Negative control samples would contain all of the reagents for the protein assay but no protein. In this example, all samples are performed in duplicate. The assay is a colorimetric assay in which a spectrophotometer can measure the amount of protein in samples by detecting a colored complex formed by the interaction of protein molecules and molecules of an added dye. In the illustration, the results for the diluted test samples can be compared to the results of the standard curve (the blue line in the illustration) in order to determine an estimate of the amount of protein in the unknown sample.

17. The Lesson of State Health-Care Reforms
October 13, 2009
Supreme Court Justice Louis Brandeis famously envisioned the states serving as laboratories, trying "novel social and economic experiments without risk to the rest of the country." And on health care, that's just what they've done.
