New Inspiration of Light Pressure explores how light, long seen as illumination, is also a directed stream of power—the arrow of light—that links energy, force, and motion. Drawing from Crookes's radiometer and Einstein's insights into radiation pressure, the book introduces the principle of force–power equivalence, revealing how every flow of energy carries intrinsic mechanical meaning. Uniting experimental observation with philosophical reflection, it offers a new framework for understanding how light not only moves matter but defines the energetic structure of reality itself.
