牛顿力学在物理学中的地位

章简要介绍了物理学发展的历史，从中引出了牛顿力学在物理学中的重要地位，以牛顿的《自然哲学的数学原理》为代表的经典力学体系的建立，是科学发展历史进程的一个重要里程碑，除此以外，牛顿还在光学、热学、数学、天学等方面为人类做出了不朽的贡献，本通过对牛顿力学内容、地位的简要介绍，使我们认识到牛顿以及牛顿力学对当今物理世界乃至全人类科学起到的巨大作用．     

牛顿力学三百年

本文简要介绍了牛顿的生平及其代表作《自然哲学的数学原理》。从物理学、科学哲学和科学史的角度探讨了牛顿力学的形成与发展、牛顿的公理方法,以及牛顿力学在中国的传播。     

“牛顿运动定律”的教材分析及教学处理

“牛顿运动定律”在力学乃至整个物理学中占有重要的地位，它是经典力学的基础，整个力学教学结构是以牛顿三大定律为核心展开的。尤其是牛顿第二定律，不仅是力学教材的重点，也是整个中专物理的重点之一。可以说，物理学作为一门科学是肇始于牛顿运动定律的，学习和掌握牛顿     

牛顿时空观

<正> 时间与空间理论对于哲学与对于物理学有着同等重要地位。可以说,不同的时空理论从根本上区别了不同的物理学体系,也从根本上提供了理解不同哲学体系的钥匙。本文拟影响了物理学也同样影响了哲学的牛顿时空观作些简要的论述。 一 要理解牛顿的时空理论的实质及其在经典物理学中的地位,应该首先弄清牛顿时空理论的出发点。关于这一点,我们可以从以下两个方面考虑。 第一,力学体系的实现,取决于时空问题的研究。牛顿力学的基本轮廓——运动三定律及万有引力定律,构建了经典力学的雄伟大厦。当我们探究其何以可能时,时空的研究是必     

正确理解牛顿三定律

牛顿运动定律在力学乃至整个物理学中占有重要的地位。它是经典力学的基础。牛顿力学三定律又是高中物理的重点内容。只有对牛顿定律正确理解,才能够熟练掌握,正确运用。     

牛顿第二定律的“五性”

牛顿第二定律是动力学的核心规律,在力学乃至整个经典物理学中均有十分重要的位置,因此在对牛顿第二定律的学习中应有科学的、全面的理解。现就牛顿第二定律的“五性”     

爱因斯坦及其六大科学成就与意义

爱因斯坦是20世纪最伟大的科学家,他的理论及思想在人类科学、哲学、思想发展过程中起着至关重要的作用．尤其是他创立的相对论,取得了前所未有的成就,其地位堪比经典力学领域的牛顿力学体系,电磁领域的麦克斯韦电磁理论,对科学及科学方法、哲学、社会有着重要的意义．     

物理学与人类科技进步--2005国际物理年

本文以牛顿力学、电磁场理论、相对论和量子力学为主线,概述了物理学的重要发展历程,阐明物理学在第一争第二次工业革命及现代科技革命中所发挥的重要作用.“2005-国际物理年“,表明科教界、政界和公众对物理学的支持和重视.     

物理学与数学

勤于思考的学生经常问:牛顿力学基本定律做出科学有力的系统论述的代表作是《自然哲学的数学原理》,怎么不是物理学原理呢?这问题的实质就是物理学与数学的关系问题。真正弄清两者的关系,既不仅对物理研究、物理教学有重要意义,而且对数学研究、数学教学同样有重要意义,从物理学发展     

“我站在巨人的肩膀上”——牛顿创立微积分的故事

在意大利科学巨星伽利略陨落的1642年,近代科学史上的经典物理学大师牛顿就“迫不及待”地来到人间。这位早产儿在他长达85年的生命旅程中,给人类带来了无价的科学发现。 他发现了力学三大定律:惯性定律,落体定律,作用与反作用定律。 他还创立了万有引力定律。 此外,牛顿对光的分解研究,打开

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
