For everyone interested in physics and astronomy, interactive applications and tests are available in the MES library.

You can learn about the scientific achievements of the outstanding German astronomer, mathematician, mechanic, optician Johannes Kepler using the materials of the library of the Moscow Electronic School. The future scientist, whose ideas were significantly ahead of the time in which he lived, was born on December 27, 1571. It was he who discovered the three laws of planetary motion, established that their orbits are elliptical, and became the author of many other studies.

For everyone who is fond of space and loves to study the starry sky, the MES library has an application Kepler’s Laws… In it, you can repeat the definitions of Kepler’s laws, find out what an aphelion, a semi-major axis and a complete cycle of changing lunar phases are.

In an interactive application “3D model of the solar system”high school students will consolidate the information they have learned about the Sun, planets and their orbits, satellites, speeds and distances, and will also test their knowledge in astronomy, mathematics and physics.

application “Gravity. Laws. 10th grade “ allows you to establish pairs of correspondences between the illustration and the name of the law, and “Star Cards. Celestial coordinates “– remember what the period of rotation of the earth around its axis is equal to, indicate the coordinates of stars and planets, using a map of the starry sky, and complete other tasks.

In the application “Astronomical dictation. Kepler’s laws “students will need to fill in the gaps in the text by choosing words from the proposed list.

High school students will be able to find correspondences between the wording of the law, its name and the author by working with an interactive application “The movement of celestial bodies under the influence of gravitational forces. Astronomy. 11th grade “… IN interactive testfor 11 grades, students will test their knowledge of astronomy. Among other things, they will remember what the first, second, third and fourth cosmic speeds are equal to.

According to legend, six-year-old Johannes Kepler witnessed the appearance of the Big Comet, and three years later – a lunar eclipse. Since then, astronomy has become his life’s work. He graduated from the monastery school and then from the Tübingen Theological Seminary. During his studies, Kepler showed outstanding abilities and, at the age of 23, was invited to lecture in mathematics at the University of Graz.

The outlook of the young scientist was formed on two basic principles: scientific and theological. While still a student, in endless arguments with fellow students, he insisted on the truth of the heliocentric system. The first major work, Mysterium Cosmographicum, created a position for him in scientific circles, although it was not very popular.

In the center of Johannes Kepler’s scientific interests are the sun and stars, planets and their movement, as well as the influence of the sky on the earth in terms of optics, meteorology and astrology. It is then that the scientist realizes how much his research is limited by the lack and inaccuracy of data.

In 1604, Kepler published Astronomiae Pars Optica, this work still remains the basis of modern optics. Johann was the first to understand the principle of inverted image projection onto the retina of the human eye. Another work – Astronomia nova – was a breakthrough in the study of planetary motion. The scientist came to the conclusion that the orbit of Mars is an ellipse, and the speed of the planet is inversely proportional to its distance from the Sun.

In 1611, calling for the final abandonment of the geocentric system, the scientist wrote the treatise Somnium. The manuscript told about a trip to the moon, it can be called the first work in the genre of science fiction. From 1615 to 1621, Johannes Kepler created a three-volume monograph Epitome Astronomiae Copernicanae, devoted to the laws of planetary motion.

Johannes Kepler’s interests and achievements were extensive – determining the volumes of bodies of revolution, using methods similar to integrals in calculating, studying symmetry, and much, much more. Kepler’s idea that the maximum packing density of balls is achieved only when they are pyramidal was confirmed only 400 years later.

How to use the MES Library The MES library contains more than one million materials

The MESh library is a service of the Moscow Electronic School project, developed by the Department of Education and Science together with Department of Information Technology… It contains a lot of educational materials: more than 50 thousand lesson scenarios and more than eight thousand video lessons, over 1600 electronic study guides, 348 textbooks, more than 130 thousand educational interactive applications, eight unique virtual laboratories, 245 works of fiction, as well as a huge number of test tasks corresponding to the content of the exam and exam, and much more.
