博士家园(http://www.math.org.cn/ http://www.bossh.net/)
简介:虽然取名为博士家园,其实它是一个致力于数学学科讨论交流的学术网站,从它的域名math和办公地址为中国科学院数学与系统科学研究院应用数学研究所看得出来,管理员应该是一些从事数学研究的专业人员。由于专业所限,在线人数不是很多(平时100人左右,最高也才347,这也许是管理员将该网站定义为“博士家园”的原因)。但它仍不失为一个学数学专业同学较好的去处,网站提供最新数学新闻、数学进展、数学软件、数学竞赛、考研(博)信息、数学问题讨论、数学资源分享等内容。特别是数学资源库提供了大量考研考博真题、数学类教科书习题解答(对理工科的大学生帮助大大的哟!)、视频教案课件、笔记讲义试卷等内容,对大家比较有用,不过貌似在购买充值卡(10元含500个下载金币)。

chemistry.about.com是我最喜欢的国外化学网站之一,它由Anne Marie Helmenstine博士负责编辑,其实算是她的一个博客吧!该博客开始于2001年,里面有好多有趣的原版实验,化学基础的东西。通过这个网站你会发现人家的化学语言是如此生活化,没有艰深的专业词汇,而且时时有幽默的调侃和自言自语似的惊讶赞叹,学习化学的过程更像一个孩子在聚精会神的玩,好自然的感觉。让你寓学于乐,轻松投入化学的精彩世界,你还不赶快去?该网站偏重于化学科普,适合学习化学的每一个人,学生可以找到书本以外的化学故事,教师可查找备课资源和学习教学风格等。
Each site in About unique network is run by a professional Guide who is carefully screened and trained by About. Guides build a comprehensive environment around each of their specific topics, including the best new content, relevant links, How-To’s, Forums, and answers to just about any question.

今天,科学堂向大家推荐SCI.POLYMERS FAQ,通过这个页面大家可以查询一些关于聚合物方面的问题:
如:What is a “Polymer” 什么是聚合物
The word Polymer comes from the Greek “poly” meaning many, and “meros”, parts or units. A polymer is a group of many units. You combine many “monomers” (individual units) to create a polymer.
Polymer is often used as a synonym for “plastic”, but many biological and inorganic molecules are also polymeric. All plastics are polymers, but not all polymers are plastics. Plastic more commonly refers to the way a material behaves under applied forces, or behaves when it melts and flows.
