Research in science and medical fields encompasses both pure and applied science, focusing on understanding natural phenomena and developing products or processes to address specific problems. Pure research aims to comprehend the universe and its workings, while applied research seeks practical applications that benefit humanity or generate profit. The process involves thorough study, including reading scientific literature to build a foundation for new experiments. Roles within research vary significantly depending on the work environment, such as a university or industry lab. Technicians and research assistants typically perform repetitive tasks and specialize in specific techniques, which are essential for the research process. In contrast, principal investigators or lab heads are responsible for conceptualizing experiments and guiding the research direction, while graduate students and post-docs occupy a middle ground, balancing hands-on work with intellectual contributions. Overall, the nature of research work can be tedious but is crucial for scientific advancement.
