Applications Of Modern Physics [better] -

Modern physics—principally quantum mechanics, relativity (special and general), and atomic and nuclear physics—underpins many technologies and scientific fields. This article surveys major applications across computing, communications, energy, medicine, materials, sensing, and fundamental and applied research, highlighting principles, implementations, limits, and near‑term directions.

Positron Emission Tomography relies on detecting gamma rays released when positrons (discovered through relativistic quantum theory) annihilate with electrons inside the body. 3. Energy Generation and Nuclear Technology Applications Of Modern Physics

High-energy ionizing radiation, such as gamma-ray beams from Cobalt-60 sources or proton beams from particle accelerators, is focused directly onto malignant tumors to destroy the DNA of cancer cells while minimizing damage to surrounding healthy tissue. 4.
