Richard P. Feynman Quotes
If science is to progress, what we need is the ability to experiment, honesty in reporting results—the results must be reported without somebody saying what they would like the results to have been—and finally—an important thing—the intelligence to interpret the results.
Feynman, Richard P. The Character of Physical Law. MIT Press, 1967, p. 148.
A null hypothesis is a statistical scientific term that a researcher assumes and uses to compare other things to. If there are no significant, found differences, the null hypothesis is not rejected. If significant differences are found, then the null hypothesis (yesterday's truth) is then rejected. In science, no one has been right for 400 years since Aristotle. Truth is never eternal. It is continuously subjected to testing and conformation and history has shown that with new instruments, new techniques and new other findings to work from, sooner or later what we think is true today turns out to not quite be so. Often it is not completely wrong, but the old "truth" turns out to be not so in all cases or situations. For example, the mechanics of Isaac Newton was assumed for a few centuries to be true. Then along came Albert Einstein and he showed that Newton was right except when objects were traveling at very high speeds when Relativity explained them. And in less than one century, we realized that Einstein's Relativity explained everything except very small particles which are better explained by Quantum Mechanics. This process of will almost certainly continue.
about Iraq possessing weapons or mass destruction This is the one of the kind of statements which many felt were prevarications to justify the President’s desire to invade Iraq. See {618461} for an example of the reaction that was generated.
Richard Phillips Feynman was an American theoretical physicist and Nobel Prize winner who made significant contributions to quantum mechanics, quantum electrodynamics, and particle physics. He's known for his work on the Manhattan Project, developing Feynman diagrams, and explaining the interactions between light and matter. While studying for his PhD, Feynman participated in the Manhattan Project and helped develop the atomic bomb. For contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga.
