La ciencia del siglo XXI al servicio de la arqueología: el caso de Teotihuacan

The lecture is a comprehensive and authoritative presentation by a leading expert in the field. Manzanilla Naim demonstrates deep knowledge of both archaeological methods and the application of scientific techniques. She provides concrete examples from her own research, which lends credibility to her claims. The argumentation is solid, as she systematically explains how each technique contributes to a more nuanced understanding of Teotihuacan society. The sources cited, such as the muon detector experiment by Luis Alvarez and the use of neutron activation, are well-established in the scientific literature. However, the lecture is aimed at a general audience, so some technical details are simplified. The title accurately reflects the content, and the lecture is well-structured. The main strength is the integration of multiple lines of evidence to build a holistic picture of the past. Potential weaknesses include the lack of critical discussion of the limitations of some techniques, and the reliance on personal experience rather than a systematic review of the literature. Overall, the lecture is highly informative and scientifically rigorous, making it an excellent resource for understanding modern archaeological science.

The title accurately reflects the content, which focuses on the application of modern scientific techniques to archaeological research at Teotihuacan.
