fundamental principles and laws of motion

major discoveries of Galileo considered two basic principles of mechanics, they had a significant impact not only on the development of mechanics and physics in general.The first of them - the principle of the constancy of the acceleration of gravity, the second - the principle of relativity for uniform motion.

In addition to these two principles, Galileo Galilei discovered the laws of constant oscillation period and the addition of movement, inertia and gravity.He found the most important laws of motion of bodies thrown at an angle, as well as they move on an inclined plane.

In 1638 published a book of Galileo "Conversations and mathematical proofs," in which he outlined his thoughts on the laws of
motion in mathematized and academic form.The range of issues discussed in the book was very wide - from problems of statics to study the strength of materials and the laws of motion of the pendulum.

invention of instruments and astronomical discoveries

In 1609, Galileo made the device, which is an analogue of the modern telescope, in its basis lay optical scheme, which involved the convex and concave lenses.With this device, scientists have observed the night sky.Subsequently, Galileo made from this device to a full-time telescope.

observations Galileo turned the idea of ​​space that existed in those days.He discovered that the moon is covered with mountains and valleys, before it was considered a smooth, discovered the phases of Venus and sunspots, pointed out that the Milky Way is composed of stars, and Jupiter is surrounded by four satellites.

astronomical discoveries of Galileo, his findings and studies settled the dispute between the supporters and followers of the teachings of Copernicus, Aristotle and Ptolemy.They were given the obvious arguments showing that the Ptolemaic system is flawed.

In 1610, scientists have invented a reverse version of the telescope - a microscope, it just changed the distance between the lenses in the telescope has created them.Even in 1592, Galileo constructed thermoscope - a modern analogue thermometer, and then invented many important applications of devices.

Creating a method of experimentation

addition to his discoveries in physics and astronomy, Galileo Galilei made history as the founder of the modern method of experimentation.Scientists believe that for the study of certain phenomena need to create a perfect world where this phenomenon free from outside influences.The object of further mathematical descriptions should be a perfect world, and the findings need to check the results of experiments in which conditions are as close to perfect.
