small world in big China先开个头儿~ 回头来写~
有意思的事情。 嘿嘿了~(转载一下)
感谢@LIVE的投递 例如:https://signup.live.com/hmnewuser.aspx?mkt=en-us&revipc=US&ts=3967950&sh=62Zm&hm=1&ru=http%3a%2f%2fmail.live.com%2f%3fnewuser%3dyes&rx=http%3a%2f%2fget.live.com%2fmail%2foverview&rollrs=04&lic=1 want to be a computer scientist? Forget maths?A new book seeks to demolish the concept that computer science is rooted in mathematics and, in particular that the notion of the algorithm is fundamental to computer science.
In particular, he says the notion of the algorithm, "has been largely ineffective as a paradigm for computer science." Fant argues that, because mathematicians, notably John Von Neumann and Alan Turing, were intimately involved with the early development of digital electronic computers in the 1940s they transplanted a mathematical model of computation, including the algorithm - commonly understood to be an exact prescription, defining a computational process, leading from various initial data to the desired result - into the fledgling science of computers.
He claims that "What is essentially a discipline of pure mathematics has come to be called "the theory of computer science," and "the notion of the algorithm has been decreed to be a fundamental paradigm of computer science" However, he says this mathematical perspective "is the wrong point of view" and is asking the wrong questions. "Mathematicians and computer scientists are pursuing fundamentally different aims, and the mathematician's tools are not as appropriate as was once supposed to the questions of the computer scientist. The primary questions of computer science are not of computational possibilities but of expressional possibilities. Computer science does not need a theory of computation; it needs a comprehensive theory of process expression." This concept of 'process expression' is, he says, a common thread running through the various disciplines of computer science. "A logic circuit is an expression of a logical process; an architecture is an expression of a continuously acting process to interpret symbolically expressed processes; a program is a symbolic expression of a process; a programming language is an environment within which to create symbolic process expression; a compiler is an expression of a process that translates between symbolic process expressions in different languages; an operating system is an expression of a process that manages the interpretation of other process expressions; any application is an expression of the application process." And, he argues, important process expressions do not qualify as algorithms. "A logic circuit is not a sequence of operations. An operating system is not supposed to terminate, nor does it yield a singular solution. An operating system cannot be deterministic because it must relate to uncoordinated inputs from the outside world. Any program utilising random input to carry out its process, such...is not an algorithm." "The notion of the algorithm," he concludes "simply does not provide conceptual enlightenment for the questions that most computer scientists are concerned with." Fant is the founder and CEO of Theseus Research, a consulting firm specialising in the design and implementation of real-time image processing systems as well as ongoing research into the theory of computers. "Computer Science Reconsidered: The Invocation Model of Process Expression" is published by John Wiley. I've read this passage just now, wondered whether we should forget maths though I wanna agree the idea~ 先生,走好。 惊闻耀文乘鹤去,
得知泪水满衣衫, 人间少了一笑星, 天上增加一笑仙。 先生品德是榜样, 音容笑貌留人间! 先引段网友的诗。 ![]() 对于昨日大师的仙逝,深表悲痛。
![]() 刚又在网上看了些关于侯先生的文章,
心情沉重。
苦守门户
面对着相声的衰落,侯耀文选择了孤独的坚守。当有的单位请侯耀文出面去演小品时,他拒绝了,他对哥哥侯耀华说:“相声是我们的家传,就是死,我也要守着相声的门户。” 发展创新
在相声的变革过程中,侯耀华和侯耀文都认识到,观众的结构在变化,欣赏趣味也在变化,相声必须要吸引青年人的兴趣,否则就会丧失生命力,甚至存在的意义。因此,侯耀华建议弟弟在创作相声时要从选题开始注意,不要局限于市民生活的圈子,要考虑题材的社会广泛性,从题材到语言以及表现手法上都要有创新意识。 “侯耀文深受父亲侯宝林的影响,继承了师父赵佩茹的衣钵,不仅继承传统,更勇于创新,为相声的发展做出了很大贡献。”王晓导演还指出:侯耀文的贡献不仅仅是自身的表演,他更注重对新人的培养。
我们这代孩子,是听着先生的相声长大的。在皇城根儿,感觉离相声很近,很亲,有一种说不出的情感。觉得侯氏两兄弟像是北京的符号,京味儿十足,同时也传达着一种精神。他们的作品曾给我们带来了无尽的快乐。悲伤之余,却是一种责任感油然而生,相声需要不断发展,其他传统文化亦然。文化的,才是世界的。我们是主人,是我们的。 先生,走好。 [转帖]让我们把坐台小姐娶回家刚朋友发来一文章,读来很有意思,转过来,一起聊聊。 前言:这是一段发生在西院食堂的对话。我们都已经毕业不少年了,有事没事老爱去学校溜溜,顺道净化净化心灵,按摩按摩眼球。如果谁看见一辆黑色锐志又停在学校里了,那就是俺又去闲逛了~~~~
