适用的哲学与认识的工具

一、适用的哲学最近几十年来,科学信息空前爆炸,以致就具体而积极地研究认识方法来说,"自然哲学"变得太广泛了.对此,物理学家、生物学家、心理学家以及其他在本学科领域进行创造性工作的专家,都应该加以研究;或者自己研究,或者和相应的科学史专家合作研究.严肃的科学著作不能没有哲学,但哲学应该是"具     

美东地区罗德河流域地下水中铝形态分布的化学平衡模式计算

美东地区的罗德河流域遭受着严重的酸沉降侵蚀．在酸性条件下,铝从土壤中大量溶解并迁移到水环境中．地表水中升高的铝浓度对鱼类产生毒害,监测地表水和土壤水中的铝形态及浓度变化已成为问题的关键．本文报导了用化学平衡模式计算法分析美东地区罗德河流域地下水中的铝形态分布,获得了有价值的结论     

A massive phytoplankton bloom induced by an ecosystem-scale iron fertilization experiment in the equatorial Pacific Ocean

The seeding of an expanse of surface waters in the equatorial Pacific Ocean with low concentrations of dissolved iron triggered a massive phytoplankton bloom which consumed large quantities of carbon dioxide and nitrate that these microscopic plants cannot fully utilize under natural conditions. These and other observations provide unequivocal support for the hypothesis that phytoplankton growth in this oceanic region is limited by iron bioavailability.     

Anthropologist fired: Stanford plays its China card
