Guest lectures are presentations given by experts or professionals in a specific field, invited to share their knowledge with students. These lectures often take place in educational settings, such as universities or colleges, and cover a wide range of topics, from science to art. The goal is to provide students with insights and real-world experiences that complement their regular coursework. During a guest lecture, the speaker typically discusses their area of expertise, shares personal experiences, and engages with students through a question-and-answer session. This interaction allows students to gain a deeper understanding of the subject matter and learn about potential career paths related to their studies.
