学术之道与媒体之义

学术之道可以有多种理解, 韩非释:“道者,万物之所然也,万理之所稽也。……万物之所以成也。故曰:‘道,理之者也。’”庄子则称:“行于万物者,道也。”并进一步阐述为“道,覆载万物者也, 洋洋乎大哉!”梁启超曾论到:“学也者,观察事物而发明其真理者     

弗洛伊德理论是赝科学吗?

许多权威学者都崇尚“有系统的实证性研究”,认为“只有能够实验的理论,才有资格称为科学”。在心理学这个特殊的研究领域也是一样,所以,弗洛伊德的理论等了二、三十年才跻进了美国教科书内,但还是没有洗刷掉‘不科学’的罪名。[1]可以说,精神分     

Inspiration in the harness of daily labor. Darwin, botany, and the triumph of evolution, 1859-1868

Charles Darwin hoped that a large body of working naturalists would embrace evolution after the Origin of Species appeared in late 1859. He was disappointed. His evolutionary ideas at first made painfully little progress in the scientific community. But by 1863 the tide had turned dramatically, and within five years evolution became scientific orthodoxy in Britain. The Origin's reception followed this peculiar trajectory because Darwin had not initially tied its theory to productive original scientific investigation, which left him vulnerable to charges of reckless speculation. The debate changed with his successful application of evolution to original problems, most notably orchid fertilization, the subject of a well-received book in 1862. Most of Darwin's colleagues found the argument of the Origin convincing when they realized that it functioned productively in the day-to-day work of science-and not before. The conceptual force of the Origin, however outwardly persuasive, acquired full scientific legitimacy only when placed "in the harness of daily labour".

Autoionization in atomic and molecular physics

The important role of ionized atoms and molecules in many aspects of physical and chemical phenomena is being increasingly recognized. Typical research areas are astrophysics and interstellar molecular syntheses; plasma physics and fusion research; aeronomy and effects of ultraviolet irradiation on high atmosphere constituents; ion-molecule reactions; mass spectrometry; fundamental research on structural problems; behaviour of excited species; quantum theory of molecular structure and chemical kinetics. This paper emphasises the role of the autoionization process and discusses some of its characteristics, as well as the experimental methods used for its study.     

钱三强与中国原子弹

20世纪50年代,我国曾不断受到帝国主义的核威协和核讹诈,迫使中国领导人下决心研制核武器。50年前的今天——1955年1月15日,中共中央书记处扩大会议上,决定建设原子能工业,从此中国开始了强国防,振国威的核弹研制事业。为纪念这个具有历史意义的日子,本刊特组编如下两篇文章以飨读者。
