Niels Bohr (1885-1962) was a Danish physicist and Nobel Prize-winner who made several fundamental contributions to our understanding of atomic physics and quantum mechanics. Many students first encounter Bohr’s thinking in Middle or High School science classes, in the form of Bohr’s model, which depicts electrons as dots on orbitals surrounding a central nucleus. Although Bohr’s model is not an accurate depiction of the atom — the position of an electron is uncertain and is better represented as a foggy probability distribution — it is pragmatically useful in teaching students the basics of atomic physics. Bohr’s model portrays how an atom has a series of energy levels electrons may occupy, called orbitals, with fixed limits on occupancy. It also shows how electrons emit and absorb photons and change energy levels accordingly. Bohr developed many of the concepts behind his model of the atom working at the University of Copenhagen. in the late 1910s and throughout the 1920s. He received
