Nuclear Physics

At the start of the twentieth century, physicists were only just starting to move beyond the view that atoms were indivisible particles of matter, an idea that had been around since ancient times (the electron was discovered by J.J. Thomson in 1897). By the end of the century, mankind had harnessed energy from the incredibly strong nuclear force, unleashed nuclear weapons on the world, developed imaging techniques using the spin of atomic nuclei, and used radioactive tracers and radioisotope therapies in medicine.
