Nicolaus Copernicus
Today in the lesson we will get acquainted with the ideas of Nicolaus Copernicus and other scientists about the Universe. Lesson topic: "From Nicolaus Copernicus to the present day".
Polish astronomer Nicolaus Copernicus believed that the center of the Universe is the Sun around which all the planets revolve. Planets also move around their axis. The stars are motionless and limit the Universe.
How do you think Nicolaus Copernicus explained the movement of stars if he believed that they were motionless? (Rotation of planets around their axis)
What are the similarities and differences between the Copernican and Ptolemaic systems? (Planets rotate in orbits and around their own axis; Ptolemy had the Earth at the center of the Universe)
Can we say that Nicolaus Copernicus described the Universe? (No, he described the solar system)
Open and read the textbook about Giordano Bruno. Can we say that Giordano Bruno's guesses were correct? Which guesses do you think are correct?
Italian scientist Giordano Bruno
The universe is infinite and has no center; (right)
The Sun is the center of the Solar System; (right)
The sun is one of many stars; (right)
Perhaps there is life in other star systems as well (not proven)
Italian scientist Galileo Galilei
For the first time I used a telescope to observe celestial bodies;
I saw irregularities on the Moon and dark spots on the Sun;
Discovered the moons of Jupiter.
Match the discovery with the conclusion that can be drawn from that discovery.
Answer: A-2, B-3, C-1
Modern idea of the Universe:
Earth is a planet in the solar system.
The solar system is part of the galaxy (Milky Way)
Our galaxy and other galaxies form supergalaxies.
All supergalaxies are part of the Universe.

Galileo Galilei discovered the moons of Mercury ( wrong)
The solar system and the Universe are one and the same ( wrong)
A galaxy is a collection of stars ( right)
Stage 5. Summing up the lesson. Homework.
Today in the lesson we got acquainted with the idea of the Universe of such scientists as N. Copernicus, G. Bruno, G. Galileo, as well as with modern ideas about the Universe.
Homework: Page 29-32 (oral retelling), Task No. 4 (oral)
For many centuries, the science of the Universe was dominated by the teachings of Ptolemy. It was accepted and supported by the church and seemed true and irrefutable. But time passed, cities grew, crafts and trade developed, Europeans learned about new countries and peoples. Discoveries of sailors of Portugal and Spain in the XIV-XVI centuries. changed the geographical map. People realized how huge the world in which they live is, and F. Magellan's trip around the world finally proved the sphericity of our planet.
The person who managed to create a new model of the Universe was the great Polish astronomer Nicolaus Copernicus (1473-1543). Observations of stars and planets, study of the works of ancient thinkers and his contemporaries, complex mathematical calculations allowed him to conclude that the Earth revolves around the Sun. The center of the world, according to Copernicus, is the Sun, around which all the planets move, rotating simultaneously around their axes. The stars, according to Copernicus, are motionless and located at enormous distances from the Earth and the Sun. Their rotation around the Earth is apparent, and it is due to the fact that our planet itself rotates around its axis, making one revolution in 24 hours. The stars form a sphere that limits the Universe.
System of the world according to Copernicus
The teachings of Copernicus immediately found supporters among scientists of the 16th century. They spread the ideas of the great astronomer in their countries, expanded and deepened them. Thus, the Italian scientist Giordano Bruno (1548-1600) believed that the Universe is infinite, it does not and cannot have a single center. The sun is the center of the solar system. But it itself is one of many stars around which planets orbit. Perhaps, J. Bruno believed, they also have life. And the solar system has not yet been fully studied; it is possible that there are still undiscovered planets in it. As it became clear later, many of these guesses by J. Bruno were correct.
Telescope of G. Galileo
Herschel's first large telescope with a mirror 1.2 m in diameter (1789)
Another Italian scientist, Galileo Galilei (1564-1642), also did a lot to develop the teachings of Copernicus. In his observations of celestial bodies, he for the first time used a telescope, which he made himself (it is now difficult to say who was the inventor of this device). Galileo's best telescope gave a magnification of only 30 times. But this was enough to see irregularities on the surface of the Moon and dark spots on the Sun. The sunspots did not remain stationary; they moved across its surface, but always in one direction. The conclusion was that the Sun rotates around its own axis. What amazed contemporaries most of all was Galileo's discovery of the moons of Jupiter. This proved that not only celestial bodies can orbit around the Earth. Introducing his discoveries to his contemporaries, Galileo pointed out the correctness of the teachings of N. Copernicus. This teaching slowly, in a fierce struggle against old prejudices, won more and more new supporters.
Ancient image of the world system according to Copernicus
A lot of time has passed since then. To create a modern model of the Universe, more than one generation of scientists worked. New devices and instruments, new research methods, and human flights into outer space were required.
Modern science assumes such a model of the Universe. Our Earth is part of the Solar System, which is part of the Galaxy (a giant cluster of stars). Our and other galaxies, in turn, form clusters of galaxies, and they form superclusters. The world of the Universe is very diverse and contains countless celestial bodies and their systems.
Scientists who changed the world
Nicolaus Copernicus was born in the Polish city of Torun. He lost his parents early and was raised by his uncle. Copernicus received his education in Krakow and then in Italy. He studied not only astronomy, but also law, medicine, and philosophy. He was a comprehensively educated man. Copernicus's ideas about the structure of the Universe are presented in his book “On the Revolutions of the Celestial Spheres,” which was published in 1543, shortly before the scientist’s death. N. Copernicus spent 30 years of hard work creating his teaching.
Nicolaus Copernicus
Giordano Bruno was born in southern Italy. Having devoted his life to the dissemination and development of the teachings of N. Copernicus, he was forced to leave his homeland and wander around many European countries. He was persecuted by the church, since the teachings of N. Copernicus were prohibited by it. At that time, the church severely punished those whose views contradicted its rules. J. Bruno was captured and, after several painful years in prison, burned in Rome on February 17, 1600. He died, but did not renounce his convictions.
Giordano Bruno
Galileo Galilei was born in the Italian city of Pisa. He received a varied education (he studied medicine, mathematics). Galileo made many scientific discoveries and was widely known. In 1632, he published the book “Dialogue on the Two Most Important Systems of the World,” in which he defended the teachings of N. Copernicus and refuted the Ptolemaic system. For this book, he was brought to trial by the church, at which he, then an old man, was forced to renounce his beliefs.

Test your knowledge
- How did the system of the world created by Copernicus differ from the system of the world according to Ptolemy?
- What are the merits of J. Bruno in the development of views about the Universe?
- What contribution did Galileo make to the study of the structure of the Universe?
- What model of the Universe does modern science offer?
Think!
Compare the Copernican system of the world and the modern model of the Universe, find similarities and differences.
The great Polish astronomer Nicolaus Copernicus created a model of the Universe, according to which the center of the world is the Sun, and the Earth and other planets revolve around it. The views of N. Copernicus were disseminated and developed by G. Bruno and G. Galileo. According to modern concepts, the Earth is part of the Solar System, which is part of a giant cluster of stars - the Galaxy. The universe is made up of a huge number of galaxies.

How the ancient Greeks saw the Earth The ancient Greeks imagined the Earth as a flat disk surrounded by a sea inaccessible to humans, from which the stars emerge every evening and into which they set every morning. The sun god Helios rose every morning from the eastern sea in a golden chariot and made his way across the sky.
