This book was written with the purpose of serving as a guide for students of Higher Education Institutions. Through practical examples, it introduces the reader to the basic principles and concepts of Quantum Mechanics.

After the first chapter, which presents the necessary mathematical knowledge, the concept of wave function and its properties are presented. In the third chapter, we will learn about the concept of operator and its application in Quantum Mechanics. In the fourth chapter, we will learn about the principle of uncertainty (Heisenberg). The fifth chapter provides a detailed analysis of discrete spectrum. 

Finally, in the sixth chapter, a basic study of problems in more than one dimension is conducted. With this book, a foundation has been laid. The reader can delve into more theoretical topics from other textbooks.
