Our Mission

Physics Forums aims to provide a community for students, scientists, educators or hobbyists to learn and discuss science as it is currently generally understood and practiced by the professional scientific community.

Our main focus is physics, but we also cater to other STEM fields including engineering, chemistry, biology, mathematics, etc.

STEM homework help for students is available, as well as academic and career guidance.
