Thiên văn học: Cơ học Thiên thể và Hệ thống Sao

Astronomy: Celestial Mechanics and Star Systems — Take Flight Among the Stars!

This is a 20-hour course where you will learn everything you need to know about the motion of celestial bodies.

It includes:

• 40 video lectures

• 20 assignments

• 100+ practice problems

• 200+ discussed examples

• Various resources and interactive simulations

We will begin by introducing the different concepts and laws that govern the Universe, then build our understanding of orbital trajectories, analyze the properties of stars, planets, galaxies, and more, and finally apply these skills to complex real systems that shape the world we live in.

From predicting planets' alignments, to tidal forces that define evolution; from collapse mechanisms causing disk formation or star births, to calculating efficient trajectories of space missions; from analyzing distant galaxies, to breaking down their complex close-up behavior — this course answers all of your questions about the curious motion of celestial bodies and strengthens your problem-solving and critical thinking skills.

Starting from the fundamentals of space exploration and ending with the modern quandaries of humanity, you will gain elite knowledge of astronomical systems, being able to solve even the most intricate questions at the highest International Olympiad level yourself!

This course is ideal for learners of all ages. Whether you are just a passionate beginner exploring the wonders of astronomy, a high-school student aiming to deepen your knowledge for exams or Olympiads, or a University undergraduate pursuing a professional-level understanding of Celestial Mechanics — you will find it a valuable experience both academically and recreationally!

You are encouraged to ask questions, try solving problems yourself using your calculator and wits, and save these materials for future reference. But most importantly, take your time and enjoy learning about the beauties of the cosmos!

Are you ready for the challenge? Come aboard our spacecraft and let's take flight among the stars!
