Std- 10 Vanijya Patravyahar and Sec.Practice Textbook
When preparing school laboratory reports, students are frequently told to present their methods clearly so that others could repeat the investigation. The conclusion that students will likely to draw from this requirement is that professional scientists are also constantly reviewing each other’s experiments to check up on each other.

Unfortunately, while such a check and balance system would be useful, the number of findings from one laboratory checked by others is small. In reality, most scientists are simply too busy and research funds too limited for this type of review. It is interesting to note that when scientific experiments are repeated it is usually because a scientific conclusion attacks the prevailing paradigm.

In the recent case of cold fusion, scientists worldwide dropped what they were doing to try to repeat the findings provided by Fleishman and Pons. In fairness, these two scientists not only assailed the conventional wisdom but presented their results in a press conference rather than in a peer-reviewed journal. Therefore, the community of scientists had two reasons to be suspicious. One can infer a measure of the disdain exhibited by the scientific community toward cold fusion and its “discoverers” in the titles of several new books on the subject.

Bad Science: The Short Life and Weird Times of Cold Fusion (Taubes, 1993) and Cold Fusion: The Scientific Fiasco of the Century (Huizenga, 1992) both tell the tale of what happens when a new idea is too far outside scientific norms – at least as far as those norms are presently perceived. The fact that cold fusion did not exist likely vindicated those who quickly attacked it, but the more interesting lesson is that is was attacked because the idea was so distant from the expectation on the part of the scientific community. The result of the lack of oversight has recently put science itself under suspicion.
