Beginning and Ending Years of Technological Revolutions Estimated by Tabular Pattern Calculations as well as Further Thinking.

In the past 200 years, five technological revolutions have occurred. What makes us curious is the information concerning the sixth and the seventh ones, as a topic of future measure. In this paper, we use the tabular pattern calculations method, which is based on the separation and combination considerations of the data, to make predictions concerning the possible beginning years and ending years of these technological revolutions. Besides, we conduct further thinking based on known data and predicted results. Moreover, we discuss the possible themes of the seventh technological revolution. Finally, we draw the summary that the fifth technological revolution would be related to 1971 - 2029; the sixth technological revolution would be related to 2029 - 2072; the seventh one would be related to 2072 - 2124.
