Te Dawn of Cząsteczki Fizyki: From Atoms to Electrons

At te close of thee 19th century, the atom was considered thee indivisible foundation of matter. That picture dissolved in 1897 whein J.J.

Simultanously, the study of radioactivity by Henri Becquerel, Marie Curie, ande Piere Curie revealed that atoms could spontanously emit energetic particles, hinting at a complex internal energy contacir. Alpha, beta, andd gamma rays were classified, andbeta decay decay would later be understood as the emission of contains from a neutroon- rich nukus. These ventama were unexplainable by classical physics, setting thee stage for thantum them revolution.

Te Nucleus Revenaled: Protony i Neutrony

In 1911, Ernest Rutherford 's gold foil experiment redirected the course of physics. Bye firing alpha particles at t thin metal foils, he observed that a tiny fraction bounced back at extreme angles. This led tte planetary model of thee atom: a dense, positivele charged nuclenucles arounded by by orbiting contros.

Through the 1930s and 1940s, experiments with cosmic rays and early accelerators uncovered a flood of new particles.

The Quark Model: Order from Chaos

By the early 1960s, the hadron spectrem was weally but bewildering. Murray Gell- Mann ande Georgie Zweig independently propose that hadron were nott elementary but composites of more fundamentaltal particles.
