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, light is composed of separate packets of energy called____.

A. electrons

B. photoelectrons

C. quanta

D. gamma rays

Giải thích:

Theo Einstein, ánh sáng bao gồm các gói năng lượng riêng gọi là

A. electron                               B. photoelectrons (quang điện)

C. tia gamma                                     D. quanta (lượng tử)

Thông tin: 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. (Trong đó, ông đề xuất rằng ánh sáng bao gồm các gói năng lượng riêng biệt, gọi là quanta hoặc photon, có một số tính chất của các hạt và một số đặc tính của sóng.)

Dịch bài đọc:

Bất kỳ danh sách những nhà tư tưởng vĩ đại nhất nào trong lịch sử đều có tên của nhà vật lý học xuất sắc Albert Einstein. Lý thuyết tương đối của ông đã dẫn đến những cách suy nghĩ hoàn toàn mới về thời gian, không gian, vật chất, năng lượng và trọng lực. Công trình nghiên cứu của Einstein đã dẫn tới những tiến bộ khoa học như việc kiểm soát năng lượng nguyên tử, thậm chí cả ti vi như một ứng dụng thực tiễn của công trình nghiên cứu của Einstein.

Năm 1902 Einstein trở thành giám khảo tại văn phòng bằng sáng chế của Thụy Sĩ tại Bern. Năm 1905, ở tuổi 26, ông đã xuất bản bài đầu tiên trong năm bài báo nghiên cứu chính. Bài đầu tiên cung cấp một lý thuyết giải thích phong trào Browni, chuyển động zig-zag của các hạt cực nhỏ trong hệ thống treo. Bài báo thứ hai đặt nền móng cho photon, hoặc lượng tử, lý thuyết về ánh sáng. Trong đó, ông đề xuất rằng ánh sáng bao gồm các gói năng lượng riêng biệt, gọi là quanta hoặc photon, có một số tính chất của các hạt và một số đặc tính của sóng.

Bài báo thứ ba chứa "lý thuyết tương đối đặc biệt" cho thấy thời gian và chuyển động tương đối so với người quan sát, nếu tốc độ ánh sáng không đổi và luật tự nhiên ở mọi nơi trong vũ trụ đều giống nhau. Bài báo thứ tư là một bổ sung toán học cho lý thuyết tương đối đặc biệt. Ở đây, Einstein trình bày công thức nổi tiếng của ông, E = m(cc), được gọi là sự tương đương khối lượng-năng lượng. Năm 1916, Einstein công bố thuyết tương đối tổng quát của ông. Trong đó ông đề xuất rằng lực hấp dẫn không phải là lực, nhưng là một đường cong trong không gian-thời gian liên tục, được tạo ra bởi sự hiện diện của khối lượng.

Einstein thường xuyên nói chuyện chống lại chủ nghĩa dân tộc, sự nổi lên của một quốc gia trên tất cả các nước khác. Ông đã phản đối chiến tranh và bạo lực và ủng hộ chủ nghĩa Zion, phong trào thiết lập một quê hương Do Thái ở Palestine. Khi phát xít Đức lên nắm quyền vào năm 1933, họ lên án những ý tưởng của ông. Sau đó ông chuyển đến Hoa Kỳ. Năm 1939 Einstein đã biết được rằng hai nhà hóa học người Đức đã phân chia nguyên tử urani. Einstein đã viết cho Tổng thống Franklin D. Roosevelt cảnh báo ông rằng kiến thức khoa học này có thể dẫn đến việc Đức phát triển một quả bom nguyên tử. Ông đề nghị Hoa Kỳ bắt đầu nghiên cứu bom nguyên tử của họ.
