"An experiment without a control is an act of faith."
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. The
"great difficulties are felt at first and these cannot be overcome except by starting from experiments .. and then be conceiving certain hypotheses ... But even so, very much hard work remains to be done and one needs not only great perspicacity but often a degree of good fortune.If we wanted to be straight, we would be (Tue 14 Dec 2004 02.55 GMT)"
Experiment"... in an experiment, there are sort of two kinds of exercises. In one, you might collect more data and bring down your s. In another, you have a concern, what we call a , and you check it, whether it exists at all or not."
Experiment"I became captivated by the edifices chemists had raised through experiment and imagination—but still I had a lurking question. Would it not be better if one could really “see” whether molecules as complicated as the sterols, or strychnine were just as experiment suggested."
Experiment"To engage in experiments on heat was always one of my most agreeable employments."
Experiment"In general, we look for a new law by the following process: First we guess it. Then we – now dont laugh, thats really true. Then we compute the consequences of the guess to see what, if this is right, if this law that we guessed is right, to see what it would imply. And then we compare the computation results to nature, or we say compare to experiment or experience, compare it directly with observations to see if it works. If it disagrees with experiment, its wrong. In that simple statement is the key to science. It doesnt make any difference how beautiful your guess is, it doesnt make any difference how smart you are, who made the guess, or what his name is. If it disagrees with experiment, its wrong. Thats all there is to it."
Experiment"Mere numbers cannot bring out... the intimate essence of the experiment. This conviction comes naturally when one watches a subject at work ... What things can happen! What reflections, what remarks, what feelings, or, on the other hand, what blind automatism, what absence of ideas!... The experimenter judges what may be going on in (the subject’s) mind, and certainly feels difficulty in expressing all the oscillations of a thought in a simple, brutal number, which can have only a deceptive precision. How, in fact, could it sum up what would need several pages of description!"
