1879年，美国科学家______________研制成功碳丝灯泡为世界带来了光明，他一生中有一千三百多种发明，被誉为_

Einstein was born in 1879 in Germany Oulmont (Ulm).As a child that he was slow,but in the 14-year-old,he was a self-study higher mathematics.In 1901 he began teaching,and later to save their own money in Zurich (Zurich) University to continue his studies,he received a doctorate in 1905,when he began the study,this research led to his famous "Theory of Relativity" .Einstein in 1914 to have been well known for community.However,at this time of the First World War broke out,a great impact on him.Hitler came to power in 1933.Einstein is due to the Jews,first lost his job and then be deprived of the nationality,escaped from Germany.Einstein went to France,Belgium,and then to Britain,in 1940 he settled in the United States,New Jersey Institute of Advanced Studies at Princeton hired him as a professor for life.5O

在冯特创立他的实验室之前,心理学像个流浪儿,一会儿敲敲生理学的门,一会儿敲敲伦理学的门,一会儿敲敲认识论的门.1879年,它才成为一门实验科学,有了一个安身之处和一个名字.（G．墨菲）

有记录的最早的心理学实验应该是1840奶奶德国心理学家韦伯通过实验发现了差别感觉阈限的定律,即韦伯定律
1879年,德国心理学家冯特在莱比锡大学创建了世界上第一个研究心理现象的实验室,这是科学心理学诞生的标志.

解题思路：解答此类题的关键是：提问要讲究一点技巧．首先提问要切中题意，其次提问质量要高一些，不能太浅．最后，提出的问题须自己能够解答，才是成功的．

问题：为什么灯丝较粗的灯泡额定功率较大？
简答：普通照明灯泡的额定电压相同为220V，当额定功率不同时，灯丝的电阻也不同．根据决定电阻大小的因素可知．越粗的灯丝在长度相同的情况下，电阻会越小，由公式P=
U2
R可知功率就会越大．

点评：
本题考点： 影响电阻大小的因素；电功率的计算．

考点点评： 本题是一道开放性试题，主要考查学生应用物理知识解释物理现象的能力．是一道中档题．

1875年,冯特应聘出任莱比锡大学哲学教授,开始了其最漫长但也是最重要的学术时期,他在那里工作了45年.
1879年,冯特在莱比锡大学建立了世界上第一个心理学实验室.该实验室的出现,应该说是心理学史上的一个里程碑,标志着新心理科学的诞生.他也因此被称为心理学之父

注意关键词“煤气”股票价格狂跌，这是因为爱迪生发明了白炽灯。电灯的明亮和清洁，导致煤气灯的销售大受影响，故出现了股票价格下降的情况。

严复先后四次参加科举考试,这是在强调a选项

Albert Einstein
Albert Einstein was considered the greatest scientist of the 20th century and one of the greatest of all time.His discoveries and theories have greatly influenced science in many fields.
Einstein was born in 1879 in Ulm,a city in Germany.As a boy,he was slow to learn to talk,but later in his childhood he showed great curiosity about nature and ability to solve difficult mathematical problems.After he left school,he went to Switzerland,where he graduated from the university with a degree in mathematics.
In 1905,Einstein began to publish a series of papers which shook the whole scientific and intellectual world,and for the theories he established in the papers he won the Nobel Prize for Physics in 1921.
Because Einstein was Jewish,when Hitler took over Germany in 1933,he had to leave the country and finally settled in the United States.There he continued his study on the structure of the universe until his death in 1955.
Among the several important discoveries Einstein made in his life,the greatest is the creation of his famous Theory of Relativity.

本题要结合条约内容和性质到理解。条约具有明显反俄性质。

是1977年发现的“哇”信号,是很有节奏的工程脉冲,此事过后便不了了之.
我个人认为不是什么外星生物发出的,古时候人们喜欢把无法解释的事归结于神灵,而现在喜欢把无法解释的事归根于外星生物.在银河系的深处很多天体的演化准备着给我们制造各式各样的信息,如果“哇”信息来自外星生物,那为什么只有短短的几十秒,而后却无法探测了呢?所以可能是天体的撞击,比如中子星的相撞等等.
即使是智慧生物,是离我们大概300光年的地方,也就是说这个信号已经过了300年才到达我们地球,我们不知道300年之后的他们是否存活,或许他们在300年中已经灭绝或许已经离开了他们所在的居所,就算我们发过去信号也要到300年后!
