Courses Do I Need Quantum Mechanics for a Future in Cosmology?

Click For Summary
Studying quantum mechanics is essential for a future in cosmology, as it provides a foundational understanding of fundamental physical principles. While classical mechanics and electromagnetism are important, a comprehensive grasp of all four key areas—classical mechanics, electromagnetism, quantum mechanics, and statistical mechanics—is necessary for a well-rounded education in theoretical physics. The current module options of Mathematical Methods, Fluid Mechanics, Cosmology, and Electromagnetism are beneficial, but incorporating quantum mechanics will enhance future studies. Ultimately, a solid background in quantum mechanics will be crucial for advanced cosmological concepts. Prioritizing these subjects will better prepare for a career in cosmology.

Hi. I'm studying a degree in maths/physics with the open university through the "combined STEM" degree programme. I wanted to know, do i require quantum mechanics modules if I wanted to focus on cosmology in the future? My current module options are: Mathematical Methods and Fluid Mechanics, Cosmology and Electromagnetism.

I figured maths is good for a theoretical physicist and fluid mechanics is good for potential work in plasma studies. Cosmology becuase obviously I'm curious about it, and electromagnetism again, because i'm curious about it.

Help is appreciated

At this level you might need classical mechanics more than EM. But for a solid background, eventually you will need all the “Four Knights”: classical mechanics, electromagnetism, quantum mechanics, and statistical mechanics.

Thread 'Uncertainty in pursuing Engineering'

This is my second year in college, and I changed my major to electrical engineering at the start of my second year. I'm taking Calc 1, and I know that I'm going to fail the course. I think there are several reasons for this. I hadn't touched math in an entire year (finished pre-calc 2 in HS), and I heard Calc 1 was the easiest math course, so I decided that taking the class without outside help (tutors or office hours) was enough. I tried really hard and spent hours learning, studying, and...
