We review solar studies using AIA, HMI, and EVE data from the SDO spacecraft that revolutionized our physical understanding of the Sun. The relevant SDO studies cover the entire 15-year lifetime of SDO, from 2010 May 1 to 2025 May 1. The discussed phenomena and their physical interpretations include (in chronological order): (1) MHD Waves and Oscillations (AIA, HMI); (2) Propagating MHD Waves (AIA); (3) Coronal Loop Cross-Sectional Temperatures (AIA); (4) Size Distributions of Solar Flare Parameters (AIA); (5) Spatio-Temporal Evolution and Diffusion (AIA); (6) The Rosner-Tucker-Vaiana (RTV) Scaling Law (AIA); (7) The Fractal-Diffusive Self-Organized Criticality Model (AIA); (8) Automated Temperature and Emission Measure Maps (AIA); (9) Automated Pattern Recognition Codes (AIA); (10) Kelvin-Helmholtz Instability in Reconnetion Outflows (AIA); (11) Hydrodstatics of Coronal Loops (AIA); (12) Magnetic Energy Dissipation (HMI); (13) Global Energetics of Solar Flares (AIA).
