最近电子社的打折简直疯狂，双十一之前就搞了数次200-100，而11月底当当的200-100/100-50，规模比之前更大（一万本），而且很多刚上架的新书也参与了进来。
有一本《DK宇宙大百科》进入了我的视野。从亚马逊的定价与出版商来看，这显然是一本科普而非教材，虽然有不少整页图片，但是文字密度也相当高，内容上也是又大又全。具体的出版参数如下： DK宇宙大百科，电子社飞思少儿，889x1194 12K 45印张，1620千字，298元。
罗斯《概率模型导论（第11版）》试译
说明：译稿为序言部分。该书将由清华大学龚光鲁教授继续翻译新版。
本教材旨在介绍初等概率论与随机过程。对于想要了解如何使用概率论来研究各个学科中（比如工程学、计算机科学、管理科学、自然科学与社会科学、运筹学）种种现象的人士，本教材是特别合适的。

It treats R as a Matlab-like software, so that you have make great progress in Ng’s machine learning course where use Matlab frequently.
Recommend R Books for Brother Sen
Welcome to my personal blog. I have been reading some R books recently, and I want to share my experiments with you.
R for Everyone is the prescribed textbook in your class, which have already accumulated many 4-stars and 5-stars reviews on Amazon. It have not been introduced to China, so I just readed the contents and reviews from audiences. RfE is new, and it deals with some packages which were developed recently. You have told me that this book involved the usage of various packages only, lacking in programming. This book, however, is for beginners, not for intermediate or advanced readers who will take advantage of the programming features. RfE is readable and accessible for you, and maybe you have to read it carefully and thoroughly in order to get an A grade.
