At the dawn of the twentieth century, classical physics faced inexplicable failures. The ultraviolet catastrophe challenged blackbody radiation theory—classical predictions suggested infinite energy at short wavelengths, contradicting experiment. The stability of atoms defied explanation: Rutherford's model predicted electrons spiraling into nuclei within microseconds.
These anomalies demanded revolution. Max Planck's 1900 hypothesis—that energy is quantized in discrete packets E = hν—resolved blackbody radiation but initially seemed ad hoc. Einstein's 1905 explanation of the photoelectric effect as light quanta (photons) elevated quantization to fundamental principle.

Excerpt from the Book
1.2 Wave-Particle Duality
Thomas Young's 1801 double-slit experiment with light established wave interference, yet nineteenth-century physics treated light as electromagnetic waves. In 1924, Louis de Broglie hypothesized matter waves: λ = h/p. Davisson and Germer's 1927 electron diffraction confirmed this startling prediction.
The double-slit experiment with electrons reveals the paradox: single electrons create interference patterns matching wave predictions, as if "knowing" both slit paths simultaneously. Installing detectors at slits destroys interference, yielding particle behavior. Wave-particle duality defies classical categorization—entities manifest wave or particle properties contextually.
