关于爱因斯坦的英语作文Title: Exploring the Genius of Albert Einstein。
Albert Einstein, one of the most renowned scientists in history, revolutionized our understanding of the universe with his groundbreaking theories. His contributions to physics, particularly in the areas of relativity and quantum mechanics, have left an indelible mark onscientific thought. In this essay, we delve into the life, work, and legacy of this extraordinary individual.Einstein was born on March 14, 1879, in Ulm, in the Kingdom of Württemberg in the German Empire. From a young age, he displayed an intense curiosity and a gift for mathematics and physics. Despite facing challenges in his early education, Einstein's passion for understanding the mysteries of the universe never waned.One of Einstein's most famous achievements is his theory of relativity, which he first proposed in 1905 withhis groundbreaking paper on special relativity. This theory revolutionized our understanding of space and time, proposing that they are not absolute but insteadintertwined in a four-dimensional continuum known as spacetime. The equation E=mc², perhaps the most famous equation in physics, emerged from his theory of special relativity, revealing the equivalence of mass and energy.Einstein later extended his theory to include gravity, culminating in the development of the general theory of relativity in 1915. This theory describes gravity as the curvature of spacetime caused by the presence of mass and energy. It provided a new framework for understanding the cosmos, predicting phenomena such as gravitational wavesand the bending of light around massive objects.In addition to his work on relativity, Einstein made significant contributions to the field of quantum mechanics, despite his initial skepticism towards its probabilistic interpretation. His work on the photoelectric effect, for which he was awarded the Nobel Prize in Physics in 1921,laid the foundation for the quantum theory of light.Einstein's scientific achievements were not limited to theoretical work; he also played a crucial role in the development of nuclear physics. His famous letter to President Franklin D. Roosevelt in 1939, warning of the potential military applications of nuclear fission, spurred the Manhattan Project, leading to the development of the atomic bomb.Beyond his scientific endeavors, Einstein was also a prominent advocate for peace, civil rights, and social justice. He was a vocal critic of nationalism, militarism, and authoritarianism, using his platform to advocate for international cooperation and disarmament.Einstein's legacy continues to inspire and influence generations of scientists, philosophers, and thinkers. His profound insights into the nature of the universe have reshaped our understanding of reality, challenging conventional wisdom and pushing the boundaries of human knowledge.In conclusion, Albert Einstein was not only a brilliant scientist but also a visionary thinker whose ideas continue to shape the way we perceive the world. His theories of relativity and quantum mechanics revolutionized physics, while his advocacy for peace and social justice reflected his deep humanity. As we reflect on his life and work, we are reminded of the power of curiosity, imagination, and perseverance in unlocking the mysteries of the cosmos.。

Einsteinsscientificachievement,爱因斯坦的科学成就All his life Albert Einstein was interested in trying to understand the laws of the Universe. He was atheoretical physicist, asking probing questions and carrying out experiments in his mind.In his Special Theory of Relativity, Einstein revolutionised the thinking about space and time. This theory provided the basis for the development of the famous equation E = mc2 which illustrates that matter and energy are interchangeable, and that a small amount of mass is made up of a large amount of energy.The year 1905 is sometimes called Einstein's annus mirabilis (miracle year). In that year he published four outstanding scientific papers:An explanation of the photoelectric effect indicating that light energy came in chunks or quanta.This changed thinking on the nature of light.A discussion of Brownian motion demonstrating the existence of molecules.The nature of space and time.The dynamics of individual moving bodies.These last two formed the basis of Einstein's Special Theory of Relativity and led to that famous equation,E = mc2.In 1921, Einstein was awarded the Nobel Prize for Physics 'for his services to theoretical physics and in particular for his discovery of the law of the 'photoelectric effect'. When he made his delayed acceptance speech in 1923, he ignored the citation and spoke on his theory of relativity.Einstein was a great intellect. He came up with explanationswhich at the time could not be verifiedexperimentally and many of his theories took a long time to be accepted even within the scientific world.Greater credence was attached to his theories as science and technology advanced sufficiently to allow experimentation involving high speed travel and nuclear reactions.It is still difficult for many people to accept or understand his theories since they require thinking beyond normal experiences.Following is an outline of the principles that Einstein developed in a number of scientific fields.Special Theory of RelativityRelativity explains the way an object appears to be relative to an observer. You can understand this if you consider yourself in a car, observing other cars. Imagine you are observing a car travelling at 20 km/h. If your car is stationary, then the other car's speed relative to you is 20 km/h. However if you are travelling alongside the car also doing 20 km/h, then the other car seems to be stationary compared to you. Its speed relative to you is zero! (Ever been at the traffic lights when another car has moved away and you thought you were rolling backwards?)Einstein developed the special theory of relativity by thinking about travelling alongside a light beam at the same speed as the light. He determined that the speed of light is constant, no matter what you are doing or how fast you are travelling, light always travels through empty space at 'the speed of light'. This means that time and length are not absolute, but depend on the relative motion of the object and the observer. If you are stationary, an object that is moving seems to get shorter and heavier, and time slows down for the object. In everyday situations, the slight changes are immeasurable, but they becomeobvious as the speed increases towards the speed of light. As the object travels closer to the speed of light, the length of the object appears closer to zero. Its height stays the same unless it moves up or down —the contraction only happens in the direction of movement. However if you are travelling at the same speed as the object, then everything looks normal! The 'contraction' of moving objects is the contraction of space itself not the object within space.In moving through space, time changes. Space and time are two parts of one whole called spacetime. If you stand still, you are only moving through time. If you move at the speed of light, you move throughspace only and not through time —time stands still. In between, you move partly through one and partly through the other!So the famous twin trip example: Twin A travels round the world at fast pace in a space ship while the twin B stands still. When twin A returns, (s)he will be younger than twin B. Twin B has moved only through time, twin A has moved partly through space and only partly through time —less time than the twin who stayed still.The Special theory of relativity also led to the most famous equation which first appeared in an article by Einstein in 1907. There is a fundamental relationship between rest energy and mass according to the equation E = mc2 where E is the rest energy of an object, m is the mass of the object and c is the velocity of light. The mass of something is a measure of the energy within it; matter and energy are interchangeable, and a small amount of mass is made up of a large amount of energy.In the 1930s nuclear fission was discovered. This gave a wayto release the energy stored in the nuclei of atoms, and the possibility of nuclear weapons was realised.The General Theory of RelativityThe Special Theory applies to objects moving in straight lines at constant speeds. Shortly after its publication, Einstein started work on generalising the theory to include curved paths and accelerating objects, considering the motion that makes planets move in orbit, and the fall of objects to the earth. This led to the equivalence principle which states that in free fall the acceleration and the force due to gravity are equivalent, and the force due to gravity is neutralised, ie in freefall you are weightless.In 1907 Einstein developed the ideas that space and time are not constant, but they change, and that gravity was a property of spacetime rather than being an external force. As he put it: "Matter tells space how to bend and space tells matter how to move." A glimpse into the workings of Einstein's four dimensional spacetime can be gained by imagining the spacetime as a rubber sheet. Stars and planets have mass and cause the sheet close to them to change shape and curve around them. Another massive object coming close will have its motion affected by this deformation of spacetime.The general theory predicted that a light beam passing near a massive object would actually be bent, and by how much. This prediction was supported during a total eclipse of the Sun in May 1919, and again by observations of a total eclipse in Australia in 1922.One of the predictions of the general theory is that the Universe is expanding, giving a basis for the 'big bang' theory of the origins of the Universe. It has also been used to explain black holes and quasars. Quantum TheoryThe nature of light had been debated for many years. Was it made up of particles or waves? Isaac Newton believed light to be made up of particles, Christiaan Huygens stated it was a wave phenomenon, and this was reinforced when Thomas Young demonstrated interference. Later Maxwell suggested and Hertz proved that light was part of the electromagnetic spectrum.In 1905 Einstein reintroduced the particle theory of light. A few years earlier, Max Planck had proposed that energy in an atom occurs in little chunks called quanta. Einstein suggested that light also existed in chunks or quanta. These quanta are now called photons. He concluded this by examining the photoelectric effect – the release of electrons from metals when light shines on them. To make this happen, the light needed to be high frequency (ultraviolet). Low frequency light (red) would not make it happen, no matter how bright the light was. Einstein explained this by thinking of light in terms of photons. Each electron is pushed out from the metal by one photon — as long as that photon has enough energy. Only high frequency light has photons with enough energy. Low frequency light has low energy photons, and no matter how many there are, none of them has enough energy to dislodge an electron.Between 1916 and 1925, Einstein made other contributions to the study of light, including the idea of stimulated emission of radiation – a concept which led to the development of the laser.Unified Field TheoryThe quest to explain gravity and electromagnetism together as aspects of a common phenomenon occupied Einstein's scientific thoughts for much of the last thirty years of his life until he died in 1955. He wanted to provide a basis to explain the Universe in a way other than quantum mechanics whichdescribed activities in terms of probabilities. He did not succeed. Since then the weak and strong nuclear forces have been discovered.Electromagnetism and the nuclear forces can be explained using quantum mechanics, and the search continues for a theory to explain everything!。
爱因斯坦的科学思想爱因斯坦是德裔美国物理学家,并且还拥有瑞士国籍,是伟大的思想家哲学家,是犹太人,是现代物理学的开创者和奠基人,是相对论——“质能关系”的提出者,“决定论量子力学诠释”的捍卫者(振动的粒子)——不掷骰子的上帝。
代表作品有《论动体的电动力学》《广义相对论的基础》,1999年12月26日,爱因斯坦被美国《时代周刊》评选为“世纪伟人”。
爱因斯坦所以能够在科学上做出划时代的贡献,是与他先进的科学思想和科学方法是分不开的。
爱因斯坦的科学成就与他的哲学思想密切相关,他坚持了一个自然科学家必然具有的自然科学唯物论的传统,吸收了斯宾诺莎等的唯理论思想以及休漠和马赫的经验论的批判精神,经过毕生对真理的追求和科学实践,形成了自己独特的科学思想和科学研究方法。
坚信自然界的统一性和合理性,相信人的理性思维能力,求得对自然界的统一性和规像姓的理解,是他生活的最高目标。
统一性思想、简单性思想、相对性思想、对称性思想作为科学活动的指导思想始终贯穿和广泛应用于他的科学探索之中。
他也是一位纯熟地运用思实证、想象与逻辑、直觉与数学等科学方法的大师。
他一生都非常关注对科学发现中的认识论和方法论的讨论,他晚年在“自述”中写道:“像我这种类型的人,一生中主要的东西,正是在于他想的是什么和他怎样想的,而不在于他所做的或者所经受的是什么。
”这说明科学思想和科学方法对于他取得的科学成就的巨大作用。
爱因斯坦的科学思想体现了物质世界统一性的思想。
自19世纪能量守恒定律发现后,许多物理学家都相信物质世界的统一性。
爱因斯坦则把探索和理解自然界的这种统一性作为他的最高目的,并贯穿于整个探索过程中。
正是因为他对自然界的统一性具有强烈的深挚的信念,所以他在1905年发表的几篇文章,都具有同一风格,在文章的起始都提出了不对称性问题,即统一性遭到破坏的问题。
狭义相对论的第一篇论文“论动体的电动力学”开头的第一句就是:“大家知道,麦克斯韦方程应用到运动的物体上时,就要引起一些不对称,而这些不对称似乎不是现象所固有的。
艾尔伯特爱因斯坦物理学的天才艾尔伯特·爱因斯坦:物理学的天才艾尔伯特·爱因斯坦(Albert Einstein)是二十世纪最杰出的科学家之一,他以其独特的天才和创新思维,为我们的物理学理论和人类对宇宙的理解做出了重大贡献。
他的相对论和光量子假设改变了我们对空间、时间和能量的理解。
本文将探讨艾尔伯特·爱因斯坦的杰出贡献和其对物理学的深远影响。
一、相对论的革命性艾因斯坦的相对论是他最著名的研究成果之一。
他在1905年提出了狭义相对论,进一步在1915年发展出广义相对论。
相对论颠覆了牛顿力学的观念,提出了新的对时空的解释。
狭义相对论主要研究了在惯性系中的物理定律,其中著名的E=mc²公式揭示了质能等效原理,也被称为质能守恒定律。
这个公式意味着质量和能量是可以相互转换的,也揭示了核能释放的原理,对核能的发展起到了重要的推动作用。
广义相对论则进一步扩展了相对论的范畴,提出了引力是由质量和能量所产生的弯曲时空所造成的。
他的理论成功地解释了水星的轨道偏移、光的弯曲以及黑洞的存在。
广义相对论对于我们对宇宙和宇宙中大规模结构的理解都起到了重要的作用。
二、光量子假设的建立除了相对论,爱因斯坦对光的性质也做出了重要贡献。
1905年,他提出了光量子假设。
在经典物理学中,认为光具有波动性,但爱因斯坦认为光也具有粒子性。
他的理论解决了光电效应的难题,即当光照射到金属上时,光子的能量可以激发出电子。
这个发现对于现代光电技术的发展以及量子力学的建立至关重要。
爱因斯坦的光量子假设为他赢得了诺贝尔物理学奖。
三、终身追求的统一场论爱因斯坦一生致力于追求统一场论的研究。
他希望找到一种理论,能够将引力与电磁力统一在一个框架下。
这种理论被称为“爱因斯坦场方程”。
爱因斯坦的追求并没有取得最终的成功,但他的尝试使物理学界产生了巨大的影响。

爱因斯坦的科学事迹爱因斯坦是著名的物理学家、思想家及哲学家。
他创立了代表现代科学的相对论,为核能开发奠定了理论基础,被公认为是自伽利略、牛顿以来最伟大的科学家、物理学家。
下面是店铺收集整理的爱因斯坦科学事迹,希望对大家有帮助~~狭义相对论的创立早在16岁时,爱因斯坦就从书本上了解到光是以很快速度前进的电磁波,他产生了一个想法,如果一个人以光的速度运动,他将看到一幅什么样的世界景象呢?他将看不到前进的光,只能看到在空间里振荡着却停滞不前的电磁场。
这种事可能发生吗?与此相联系,他非常想探讨与光波有关的所谓以太的问题。
以太这个名词源于希腊,用以代表组成天上物体的基本元素。
17世纪的笛卡尔和其后的克里斯蒂安·惠更斯首创并发展了以太学说,认为以太就是光波传播的媒介,它充满了包括真空[真空]在内的全部空间,并能渗透到物质中。
与以太说不同,牛顿提出了光的微粒说。
牛顿认为,发光体发射出的是以直线运动的微粒粒子流,粒子流冲击视网膜就引起视觉。
18世纪牛顿的微粒说占了上风,19世纪,却是波动说占了绝对优势。
以太的学说也大大发展:波的传播需要媒质,光在真空中传播的媒质就是以太,也叫光以太。
与此同时,电磁学得到了蓬勃发展,经过麦克斯韦、赫兹等人的努力,形成了成熟的电磁现象的动力学理论——电动力学,并从理论与实践上证明光就是一定频率范围内的电磁波,从而统一了光的波动理论与电磁理论。
以太不仅是光波的载体,也成了电磁场的载体。
直到19世纪末,人们企图寻找以太,然而从未在实验中发现以太,相反,迈克耳逊莫雷实验却发现以太不太可能存在。
电磁学的发展最初也是纳入牛顿力学的框架,但在解释运动物体的电磁过程时却发现,与牛顿力学所遵从的相对性原理不一致。
按照麦克斯韦理论,真空中电磁波的速度,也就是光的速度是一个恒量;然而按照牛顿力学的速度加法原理,不同惯性系的光速不同。
例如,两辆汽车,一辆向你驶近,一辆驶离。
你看到前一辆车的灯光向你靠近,后一辆车的灯光远离。

爱因斯坦主要科学成就1.早期工作爱因斯坦早期的工作主要在热力学和统计物理方面,在1900—1904年间,他每年都发表一篇论文发表在德国《物理学杂志》。
这些早期的工作为他在1905年辐射理论和分子动理论方面的重大突破奠定了基础。
2.1905年的奇迹1905年,爱因斯坦在科学史上创造了一个无先例的奇迹。
这一年他写了6篇论文,在3月到9月这半年中,利用在专利局每天8小时工作以外的时间,在三个领域作出了四个有划时代意义的贡献。
分别是:(1)光量子论,提出光量子假说。
(2)分子动理论,1905年4月、5月、12月他发表了三篇有关布朗运动的论文,为解决半个多世纪来科学界和哲学界争论不休的原子是否存在的问题做出了突出贡献。
(3)创立狭义相对论爱因斯坦写了一篇开创物理学纪元的长论文《论动体的电动力学》,完整地提出狭义相对性理论。
这是他10年酝酿和探索的结果,它在很大程度上解决了19世纪末出现地古典物理学的危机,推动了整个物理学理论的革命。
(4)质能相当性1905年9月,爱因斯坦写了一篇短文《物体的惯性同它所含的能量有关吗?》,作为相对论的一个推论,揭示了质量(m)和能量(E)的相当性:E=mc2,并由此解释了放射性元素(如镭)所以能释放出大量能量的原因。
质能相当性是原子核物理学和粒子物理学的理论基础,也为40年实现的核能的释放和利用开辟了道路。
3.量子论的进一步开拓爱因斯坦的光量子论的提出,遭到几乎所有老一辈物理学家反对。
尽管如此,他依然孤军奋战,坚持不懈地发展量子理论。
他把量子概念扩展到物质内部振动、光化学现象及统计物理学的研究中,在许多领域中做出了开拓性成就。
4.广义相对论的探索狭义相对论建立后爱因斯坦并不感到满足,力图把相对性原理的适用范围推广到非惯性系。
他从伽利略发现的引力场中一切物体都具有同一加速度(即惯性质量同引力质量相等)这一古老实验事实找到了突破口,于1907年提出了等效原理,此后经过曲折的探索终于1915年完成了被公认为人类思想史中最伟大的成就之一的广义相对论。
爱因斯坦的科学功绩□吴忠超爱因斯坦是历史上继牛顿之后最伟大的科学家。
他是狭义相对论的重要发现者,他对量子理论的创立具有重大的贡献,而广义相对论,亦即现代引力论的建立,则应全部归功于他。
十九世纪末期,麦克斯韦成功地把电学和磁学统一在他的电磁理论中,从他的方程推导出,电磁波在真空中传播的速度刚好是光速,于是他断定光波应是电磁波的一种。
麦克斯韦因为家族遗传的疾病,只活了四十八岁,因此没有看到电磁波实验的成功。
在牛顿的绝对空间、绝对时间以及伽利略的旧的相对性原理框架中,只有以无限速度运动的物体,在相对匀速运动的坐标系中才具有相同的速度,即无限速度。
而牛顿的万有引力认为是以无限速度传递的,所以在麦克斯韦之前,牛顿物理学被认为是自洽的,而电磁波是以有限速度传播的,在旧的相对论框架中,它的速度会因坐标系的选取而改变,这样他的方程只能在一个特定的坐标系中成立,这个坐标系被认为是相对于一种称为以太的媒介静止。
于是寻求以太的存在便成为科学的主题。
迈克尔逊——莫雷实验的结果否认了以太的存在。
爱因斯坦在1905年发表了一篇题为“运动物体的电动力学”的论文,指出如果将时间和空间组成四维的时空,而在参考系进行相对匀速运动时,时空坐标遵照所谓的洛伦兹线性变换,则一切物理定律包括麦克斯韦方程都应采取相同的形式。
这样一来,以太的存在便完全是多余的。
爱因斯坦在发表狭义相对论之前是否知悉迈克尔——莫雷的实验仍是科学史上的一个悬案。
这篇论文抛弃了牛顿的绝对时空观,导致物理学上的一场革命。
由洛伦兹变换导出的尺缩、钟慢以及双生子佯谬都和人们的直觉相抵触。
而著名的质能等效公式则是核能乃至核武器的理论根据。
1900年普朗克为了解决黑体辐射的紫外灾难问题,提出了辐射的量子理论,即是光辐射必须采取一种称作量子的波包形式。
但是只有在爱因斯坦提出光子理论之后,人们才真正接受光可以粒子即光子的形式存在。
普朗克曾经是爱因斯坦关于狭义相对论第一篇论文的审稿人。

Einsteinsscientificachievement,爱因斯坦的科学成就All his life Albert Einstein was interested in trying to understand the laws of the Universe. He was atheoretical physicist, asking probing questions and carrying out experiments in his mind.In his Special Theory of Relativity, Einstein revolutionised the thinking about space and time. This theory provided the basis for the development of the famous equation E = mc2 which illustrates that matter and energy are interchangeable, and that a small amount of mass is made up of a large amount of energy.The year 1905 is sometimes called Einstein's annus mirabilis (miracle year). In that year he published four outstanding scientific papers:An explanation of the photoelectric effect indicating that light energy came in chunks or quanta.This changed thinking on the nature of light.A discussion of Brownian motion demonstrating the existence of molecules.The nature of space and time.The dynamics of individual moving bodies.These last two formed the basis of Einstein's Special Theory of Relativity and led to that famous equation,E = mc2.In 1921, Einstein was awarded the Nobel Prize for Physics 'for his services to theoretical physics and in particular for his discovery of the law of the 'photoelectric effect'. When he made his delayed acceptance speech in 1923, he ignored the citation and spoke on his theory of relativity.Einstein was a great intellect. He came up with explanationswhich at the time could not be verifiedexperimentally and many of his theories took a long time to be accepted even within the scientific world.Greater credence was attached to his theories as science and technology advanced sufficiently to allow experimentation involving high speed travel and nuclear reactions.It is still difficult for many people to accept or understand his theories since they require thinking beyond normal experiences.Following is an outline of the principles that Einstein developed in a number of scientific fields.Special Theory of RelativityRelativity explains the way an object appears to be relative to an observer. You can understand this if you consider yourself in a car, observing other cars. Imagine you are observing a car travelling at 20 km/h. If your car is stationary, then the other car's speed relative to you is 20 km/h. However if you are travelling alongside the car also doing 20 km/h, then the other car seems to be stationary compared to you. Its speed relative to you is zero! (Ever been at the traffic lights when another car has moved away and you thought you were rolling backwards?)Einstein developed the special theory of relativity by thinking about travelling alongside a light beam at the same speed as the light. He determined that the speed of light is constant, no matter what you are doing or how fast you are travelling, light always travels through empty space at 'the speed of light'. This means that time and length are not absolute, but depend on the relative motion of the object and the observer. If you are stationary, an object that is moving seems to get shorter and heavier, and time slows down for the object. In everyday situations, the slight changes are immeasurable, but they becomeobvious as the speed increases towards the speed of light. As the object travels closer to the speed of light, the length of the object appears closer to zero. Its height stays the same unless it moves up or down —the contraction only happens in the direction of movement. However if you are travelling at the same speed as the object, then everything looks normal! The 'contraction' of moving objects is the contraction of space itself not the object within space.In moving through space, time changes. Space and time are two parts of one whole called spacetime. If you stand still, you are only moving through time. If you move at the speed of light, you move throughspace only and not through time —time stands still. In between, you move partly through one and partly through the other!So the famous twin trip example: Twin A travels round the world at fast pace in a space ship while the twin B stands still. When twin A returns, (s)he will be younger than twin B. Twin B has moved only through time, twin A has moved partly through space and only partly through time —less time than the twin who stayed still.The Special theory of relativity also led to the most famous equation which first appeared in an article by Einstein in 1907. There is a fundamental relationship between rest energy and mass according to the equation E = mc2 where E is the rest energy of an object, m is the mass of the object and c is the velocity of light. The mass of something is a measure of the energy within it; matter and energy are interchangeable, and a small amount of mass is made up of a large amount of energy.In the 1930s nuclear fission was discovered. This gave a wayto release the energy stored in the nuclei of atoms, and the possibility of nuclear weapons was realised.The General Theory of RelativityThe Special Theory applies to objects moving in straight lines at constant speeds. Shortly after its publication, Einstein started work on generalising the theory to include curved paths and accelerating objects, considering the motion that makes planets move in orbit, and the fall of objects to the earth. This led to the equivalence principle which states that in free fall the acceleration and the force due to gravity are equivalent, and the force due to gravity is neutralised, ie in freefall you are weightless.In 1907 Einstein developed the ideas that space and time are not constant, but they change, and that gravity was a property of spacetime rather than being an external force. As he put it: "Matter tells space how to bend and space tells matter how to move." A glimpse into the workings of Einstein's four dimensional spacetime can be gained by imagining the spacetime as a rubber sheet. Stars and planets have mass and cause the sheet close to them to change shape and curve around them. Another massive object coming close will have its motion affected by this deformation of spacetime.The general theory predicted that a light beam passing near a massive object would actually be bent, and by how much. This prediction was supported during a total eclipse of the Sun in May 1919, and again by observations of a total eclipse in Australia in 1922.One of the predictions of the general theory is that the Universe is expanding, giving a basis for the 'big bang' theory of the origins of the Universe. It has also been used to explain black holes and quasars. Quantum TheoryThe nature of light had been debated for many years. Was it made up of particles or waves? Isaac Newton believed light to be made up of particles, Christiaan Huygens stated it was a wave phenomenon, and this was reinforced when Thomas Young demonstrated interference. Later Maxwell suggested and Hertz proved that light was part of the electromagnetic spectrum.In 1905 Einstein reintroduced the particle theory of light. A few years earlier, Max Planck had proposed that energy in an atom occurs in little chunks called quanta. Einstein suggested that light also existed in chunks or quanta. These quanta are now called photons. He concluded this by examining the photoelectric effect – the release of electrons from metals when light shines on them. To make this happen, the light needed to be high frequency (ultraviolet). Low frequency light (red) would not make it happen, no matter how bright the light was. Einstein explained this by thinking of light in terms of photons. Each electron is pushed out from the metal by one photon — as long as that photon has enough energy. Only high frequency light has photons with enough energy. Low frequency light has low energy photons, and no matter how many there are, none of them has enough energy to dislodge an electron.Between 1916 and 1925, Einstein made other contributions to the study of light, including the idea of stimulated emission of radiation – a concept which led to the development of the laser.Unified Field TheoryThe quest to explain gravity and electromagnetism together as aspects of a common phenomenon occupied Einstein's scientific thoughts for much of the last thirty years of his life until he died in 1955. He wanted to provide a basis to explain the Universe in a way other than quantum mechanics whichdescribed activities in terms of probabilities. He did not succeed. Since then the weak and strong nuclear forces have been discovered.Electromagnetism and the nuclear forces can be explained using quantum mechanics, and the search continues for a theory to explain everything!。
