Có lần, một người hỏi Einstein: "Thưa ông, ông vui lòng cho tôi biết lý thuyết tương đối mà ông đã tìm ra; tôi không thể sửa chữa nó trong đầu!". Sau đó, Einstein giải thích bằng một ví dụ đơn giản và thực tế. Đó là: Nếu ai đó, đặt bạn ngồi trên chảo thì bạn sẽ cảm thấy một giây là cả một thời đại; và nếu bạn ngồi cạnh một cô gái xinh đẹp, bạn sẽ cảm thấy một thời đại như một giây. Ông nói: '' Đó là lý thuyết tương đối ''. Thật là một câu chuyện đáng yêu!

Once, a man asked Einstein: "Sir, would you please tell me the theory of relativity you have found; I can't fix it in my head!".

Then Einstein explained with a simple and practical example.

That is: If someone, put you on a pan, you will feel like a second is an era; and if you sit next to a beautiful girl, you will feel an era like a second.

"It's the theory of relativity," he said.

 

What a lovely story!
Yes, I feel the same, Ms. Thu Hong

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

        Any list of the greatest thinkers in history contains the name of the brilliant physicist Albert Einstein. His theories of relativity led to entirely new ways of thinking about time, space, matter, energy, and gravity. Einstein's work led to such scientific advances as the control of atomic energy, even television as a practical application of Einstein's work. In 1902 Einstein became an examiner in the Swiss patent office at Bern. In 1905, at age 26, he published the first of five major research papers.

        The first one provided a theory explaining Brownian movement, the zig-zag motion of microscopic particles in suspension. The second paper laid the foundation for the photon, or quantum, theory of light. In it he proposed that light is composed of separate packets of energy, called quanta or photons, that have some of the properties of particles and some of the properties of waves. A third paper contained the "special theory of relativity" which showed that time and motion are relative to the observer, if the speed of light is constant and the natural laws are the same everywhere in the universe.

        The fourth paper was a mathematical addition to the special theory of relativity. Here Einstein presented his famous formula, E = mc2, known as the energy mass equivalence. In 1916, Einstein published his general theory of relativity. In it he proposed that gravity is not a force, but a curve in the space-time continuum, created by the presence of mass. Einstein spoke out frequently against nationalism, the exalting of one nation above all others. He opposed war and violence and supported Zionism, the movement to establish a Jewish homeland in Palestine. When the Nazis came to power in 1933, they denounced his ideas.

        He then moved to the United States. In 1939 Einstein learned that two German chemists had split the uranium atom. Einstein wrote to President Franklin D.Roosevelt warning him that this scientific knowledge could lead to Germany developing an atomic bomb. He suggested the United States begin its own atomic bomb research.

According to Einstein's special theory of relativity,_______.

A. all properties of matter and energy can be explained in a single mathematical formula

B. light is composed of separate packets of energy

C. time and motion are relative to the observer

D. some solids emit electrons when struck by light

Albert Einstein is best known for his Theories of Relativity. He has been acknowledged as one of the greatest scientists in human history.

Born in Germany in 1879, Einstein did poorly in all his school subjects, with the exception of Mathematics, which was his favourite subject.

While working as a clerk in Switzerland, Einstein produced the Special Theory of Relativity. This theory states that mass, length and time changes, depending on how a person looks at it.

In 1915, Einstein published his General Theory of Relativity. This new theory created a controversy because many scientists did not agree with him.

In the end, some simple experiments proved Einstein to be correct. Einstein was awarded the Nobel Prize for his work in physics.
