物理学咬文嚼字之十四：正经正典与正则

"正"字在汉语里是绝对的褒义词,和"正"字结合的词组大约都可以作正面的解读."正"字字面上为"足前方"的意思,即(双)脚之前方为正.这个字包含很深的、朴素的科学道理:平面内事物的定标需选取参考方向,参考方向是任意的,且一簇平行线规定唯一的、相同的方向."正" 字的正面意思为带"正"字的事物带来了不可估量的附加价值,甚至具有道德制高点的含义.派别子系间的正宗之争,官位上的正副之争,便是聪明人也不得不投身其中.孔子有"席不正不坐,割不正不食"的说法,算来未必最极端.明亡以后,南方各地关于明正朔之争甚至造成血流成河的惨烈局面,给本已覆亡的中华民族又雪上加霜."正"字的威力,不可不察.     

读者来信

编者按 自2007年第7期开辟"物理学咬文嚼字"专栏以来迄今已经刊登了15篇,有不少读者向编辑部和作者来信表达对该栏目的关注,并与作者就文章中的一些问题进行交流和探讨,我们很高兴地看到该栏目引起读者对物理学名词讨论的兴趣.     

为了遥远的祭奠——漫话海森伯

最初,我深为惊恐.我感到,通过原子现象的表面,我正在窥测着一个奇妙的内部,而对自然界如此慷慨地展现在我面前的丰富的数字结构,使我感到眼花缭乱.     

Grid—Enabled Data Access in the ATLAS Athena Framework

Athena is the common framework used by the ATLAS experiment for simulation,reconstruction,and analysis,By design,Athena supports multiple persistence services,and insulates users from technology-specific persistence details.Athena users and even most Athena package developers should neither know nor care whether data come from the grid or from local filesystems.nor whether data reside in object databases,in ROOT or ZEBRA files,or in ASCII files.In this paper we describe how Athena applications may transparently take advantage of emerging services provided by grid software today-how data generated by Athea jobs are registered in grid replica catalogs and other collection management services,and the means by which input data are identified and located in a grid-aware collection management environment.We outline an evolutionary path toward incorporation of grid-based virtual data services,whereby locating data may be replaced by locating a recipe according to which that dta may be generated.Several implementation scenarios,ranging from lowlevel grid catalog services(e.g.,from Globus)through higher-level services such as the Grid Data Management Pilot (under development as part of the European DataGrid porject,in collaboration,with the Particle Physics Data Grid)to more conventional database services,and a common architecture to support these various scenarios,are also described.     

物理学难题选登V解答

题解134考虑一座平均密度为P的“盒子形状”的山脉，其底部面积A，高度为h．要使其底部厚度为d、比热为L的一层熔化，所需的能量为AdpL．山脉的总质量近似为Ahp，并且如果山脉下降一定的距离d所释放的能量为Ahpgd．     

物理学咬文嚼字之二量子与几何

中文“量子”是对西文“Quantum”的翻译。“Quantum”（复数形式为Quantus）是拉丁语，意思为多少（how much）。拉丁语古谚语云：“Res in tantum intelligitur，in quantum amatur”，译成中文就是“事物被爱到什么程度（置于多少爱之下），才会被理解到什么程度”，可看作是对“quantum”的应用举例。
