4. Galileo and his telescope First Paradigm: For thousands of years, Science was about empirically describing natural phenomenon 4

5. Second Paradigm:Theoretical Science using models and generalization Newton Keplar Maxwell 5

6. Third Paradigm:Computational Science: Simulating Complex Phenomenon 6 Over the last 25 years Scientists have used computer simulation to validate theories. A hurricane computer simulation.

7. Are You Living In a Computer Simulation? Nick Bostrom. Philosophical Quarterly, 2003, Vol. 53, No. 211, pp. 243-255. [html] [pdf] (An earlier draft was circulated in 2001.) ABSTRACT. This paper argues that at least one of the following propositions is true: (1) the human species is very likely to go extinct before reaching a “posthuman” stage; (2) any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof); (3) we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed. 7

8. Fourth Paradigm:Data Intensive Science The scientific method was traditionally driven by hypothesis. First scientists predict a good response, then collect experimental data to validate the data against its predictions. However, in the new data-driven approach researchers start with collecting data and analyze data later. 8

10. Collaboration is the key to good science Isaac Newton famously remarked in a letter to his rival Robert Hookedated February 5, 1676 that: "What Descartes did was a goodstep. You have added much several ways, and especially in taking the colours of thin plates into philosophical consideration. If I have seen a little further it is by standing on the shoulders of Giants." 10
