计算思维操作性定义;汇报提纲;缘与使命; Dragon Lady In 1983, I went to China for two months with a Chinese-American student tour group. We spent two weeks in Xian, where we were each handed a sword, and every morning we had to wake up at 5 oclock and we were supposed to learn this sword dance. I really took to it. To me, it was like ballet. ;缘与使命;汇报提纲;Peter J. Denning;对计算本质认知的变革;对计算本质认知的变革;Scientists from many fields were saying they had discovered information processes in the deep structures of their fields. Biology Nobel Laureate and Caltech President David Baltimore “Biology is today an information science. The output of the system, the mechanics of life, are encoded in a digital medium and read out by a series of reading heads. Biology is no longer solely the province of the small laboratory. Contributions come from many directions.”(The Invisible Future, Wiley, 2001,p. 45.);Natural information processes.: nature long ago learned how to encode information about organisms in DNA and then to generate new organisms from DNA through its own computational methods. Physics Physicists said that quantum waves carry information that generates physical effects. They have made significant advances with quantum computation and quantum cryptography. Nobel Laureate Richard Feynman became famous for showing that quantum electrodynamics (QED) was nature’s computational method for combining quantum particle interactions. In his book A New Kind of Science (2002), Stephen Wolfram proclaimed that nature is written in the language of computation, challenging Galileo’s claim that it is written in mathematics. Jeanette Wing has concluded that computational concepts are deeply embedded into everyday thinking in many fields .

Karp提出的“计算透镜”（Computational Lens）理念被认为是未来二十年计算机科学可能的发展方向之一。 其核心理念是将计算作为一种通用的思维方式，通过这种广义的计算（涉及信息处理、执行算法、关注复杂度）来描述各类自然过程和社会过程，从而解决各个学科的问题。 这一理念试图将计算机科学由最初的数值计算工具、仿真
