Scientifics Theories
In science, a theory is a reasonable explanation of observed Coogi Jeansevents that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. rosetta stone spanishA good example of this is found in the kinetic molecular theory, in which gases arewholesale football jerseys pictured as being made up of many small particles that are in constant motion.
A useful theory, in addition to explaining past observationsCHANEL HANDBAGS, helps to predict events that have not as yet been observed. After a theory has been publicized, scientists dnike air max 90esign experiments to test the theory. If observations confirm the scientists predictions, the theory is supported. If observations do not confirm the predictions, christian louboutin salethe scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected.
Science involves imagination and creative thinking as well as collecting informationchicago blackhawks jerseys and performing experiments. Facts by themselves are not science. As the mathematician Jules Henri Poincare said,ed hardy hoodies "Science is built with facts just as a house is built with bricksAbercrombie and Fitch, but a collection of facts cannot be called science any more than a butterfly valvepile of bricks can be called a house."
Most scientists start an investigation by finding out what other sseamless steel pipecientists have learned about a particular problem. After known facts have been gathered, the scientist comes to theyiwu tradepart of the investigation that requires considerable imagination. Possible solutionsMenu Holder to the problem are formulated. These possible solutions are called hypotheses.
In a way, any hypothesis is a leap into the unknown.solar water heater supplier It extends the scientists thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observationselectrolytic capacitor to test hypotheses. Without hypothesis, further investigation lacks purpose and directionsolar light supplier. When hypotheses are confirmed, they are incorporated into theories.
