View full lesson: ed.ted.com/lessons/how-does-an-atom-smashing-particle-accelerator-work-don-lincoln An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln explains how scientists harness the power of both electric and magnetic fields to smash atoms, eventually leading to major discoveries about the matter in our universe.
