Abstract: Through a study of the prizewinning scientific discoveries of the Nobel Prizes for Natural Science, we can discuss three basic and interrelated questions. First, were prizewinning achievements of the Nobel Prizes for Natural Science discovered or invented? Based on the broad concept of scientific discovery, the answer is that the essence of a scientific discovery is a complex and creative practice by mankind; regardless of the discoveries of scientific facts or the discoveries of scientific theories, discoveries are in essence discoveries including inventions. Second, what is the “discovery period” of the prizewinning scientific discoveries of the Nobel Prizes for Natural Science? The concept of “discovery period” is put forward and clarified in the paper. The main nature and properties of the “discovery period” are revealed based on statistical analysis, which has proved the “TenYear Rule” in the statistical sense. Third, how are prizewining scientific discoveries of the Nobel Prizes for Natural Science made? Through the case analysis of the specific processes that some noble prize winners carried out, this paper puts forward and explains the logicsuper logic mode of scientific discovery, elucidates respectively the view that a scientific discovery begins with the raising of questions and ends with the solution of questions and the view that many scientific discoveries are the results of accidental opportunities, and finally manifests some traits and virtues that prizewinners of important discoveries have acquired

Key words:  , Nobel Prize for Natural Science, scientific discoveries, “TenYear Rule”, logicsuper logic mode, discoveries resulting from accidental opportunities, statistical analysis,  , case analysis
