Nuclear Physics
The scientific field studying atomic nuclei — their structure, stability, and transformations through fission, fusion, and radioactive decay — is nuclear physics, whose discoveries produced both the most powerful energy source and the most destructive weapons in human history.
Overview
Fission of heavy nuclei releases energy enabling nuclear power plants to generate electricity without greenhouse gas emissions; fusion of hydrogen isotopes, which powers the sun, promises abundant clean energy if the engineering challenge of magnetic or inertial containment can be solved.
Why it matters
Nuclear physics fundamentally transformed international relations by creating deterrence theory and mutually assured destruction, while in medicine it enabled PET scanners and radiation therapy that advance cancer diagnostics and treatment with spatial precision.
