AB In this work we analyze the main aspects related to the appearance and development of bosonicstring theory from an introductory point of view and with the knowledge obtained during the degree.First, we present the tools that modern physics uses to solve problems, the Principle of least action,and we work on some examples such as the action of the free particle with the aim of establishingthe knowledge for the resolution of the movement of the relativistic particle, and study later themovement of the relativistic string. We carry out a brief review of the events that gave rise tothis theory of bosonic strings as well as other theories that emerged with the aim of unifying thefour forces: the gravity force, the electromagnetic force, the weak force and the strong force. Wecontinue the study looking for symmetries and conserved quantities that will significantly reduce thecomplexity of the problem at hand. We carry out two types of quantization in our theory: canonicaland light cone quantization, and we obtain the mass spectrum for bosonic strings. Finally, we discussthe current situation of string theory, the problems it has solved and the ones it intends to solve inthe future.
