宇宙的構造

廣泛地展開自然科學中關於物質和宇宙的構造方面知識的宣傳,對於破除迷信、建立科學的宇宙觀起着巨大的作用。這種工作也是科學館、圖書館、文化宫、文化館(站)等宣傳機構中的經常任務之一。目前在我國,人们很需要這方面的知識,可是這種工作做得很不夠,特別是很不普通。形象化的展覽是容易收到效果的,然而這方面的資料尤其缺乏。     

有用矿物的生成

各种金属矿物——铁、铜、铝等和非金属矿物——食盐、钾盐、煤、石油和磷块岩等,所有这些巨大的财富都是在地球内部或地球表面上生成的。在地球表面上生成的矿物叫做沉积矿产;在地球内部深处生成的叫做深成矿产。流动的水——小溪和河流,冲击着河岸,从河岸上带走了石头、砾石、砂子和泥土的细粒,然後把它们沉积在河床、海底及湖底的平静的水中,生成由黏土和砂子构成的沉积岩的堆积。河流带入海洋及湖沼中的不仅是固体的细粒,同时还带入溶解的物质——盐类。在干燥及炎热的地带,海水猛列地蒸发着。这种蒸发的效力,在接连着一个狭小海峡

A summer program designed to educate college students for careers in bioinformatics

A summer program was created for undergraduates and graduate students that teaches bioinformatics concepts, offers skills in professional development, and provides research opportunities in academic and industrial institutions. We estimate that 34 of 38 graduates (89%) are in a career trajectory that will use bioinformatics. Evidence from open-ended research mentor and student survey responses, student exit interview responses, and research mentor exit interview/survey responses identified skills and knowledge from the fields of computer science, biology, and mathematics that are critical for students considering bioinformatics research. Programming knowledge and general computer skills were essential to success on bioinformatics research projects. General mathematics skills obtained through current undergraduate natural sciences programs were adequate for the research projects, although knowledge of probability and statistics should be strengthened. Biology knowledge obtained through the didactic phase of the program and prior undergraduate education was adequate, but advanced or specific knowledge could help students progress on research projects. The curriculum and assessment instruments developed for this program are available for adoption by other bioinformatics programs at http://www.calstatela.edu/SoCalBSI.
