The solution to Schrödinger’s equation is a wave that describes the quantum aspects of a system. Schrödinger was inspired by de Broglie’s idea of wave-particle duality. Schrödinger did not like Heisenberg’s formulation of quantum mechanics – matrix mechanics – since it lacked visualization and was mostly mathematical. The equation was revolutionary as it solved one of the greatest problems in the quantum-mechanical model of the atom. This equation brought him the 1933 Nobel Prize in physics, along with Paul Dirac. The time-dependent version of Schrödinger’s equation also relates the Hamiltonian with time. The equation describes the Hamiltonian operator, which when operated on an abstract mathematical function called the wave function, produced energy as a result. He came up with an equation which could be used to find the energy states of an atom. As his background with eigenvalue problems would suggest, he believed that atomic spectra should be determined by some kind of eigenvalue problem.

His greatest achievement, however, was yet to come.Įrwin Schrödinger was not happy with Niels Bohr’s old quantum theory. During his time at the University of Zurich, Schrödinger published a lot of papers on thermodynamics. Schrödinger mastered the concept of eigenvalues in continuous media, and did a lot of experimenting. He also had interests in poetry and philosophy.Īt the University of Vienna, Schrödinger met many talented physicists, including Ludwig Boltzmann’s successor Fritz Hasenöhrl, and Franz Exner. The post Schrödinger’s equation and the half-dead cat appeared first on Test & Measurement Tips.On 12th August 1887, a man who would go on to revolutionize not only the field of physics, but also biology, was born.įrom a very young age, Erwin Schrödinger had shown immense talent for mathematics and physics. Throughout life he maintained an intense interest in Vedantic philosophy, and he certainly deserves credit for the fact that although raised in a Christian household, he vigorously opposed Nazi anti-Semitism in the 1930’s, escaping persecution by relocating to England in the face of certain retaliation. In addition, there were spiritual and political dimensions to this great individual’s thought. We have examined some of Schrödinger’s technical achievements that go far beyond the Cat Paradox. It cannot be said at this time that he achieved success in this venture, but much of Schrödinger’s early work remains relevant. In the 1940’s, Schrödinger attempted to devise a Unified Field Theory that would synthesize our knowledge of gravity, electromagnetism and nuclear forces within the perspective of Einstein’s General Relativity. Later in life he backed away from the probabilistic aspect of conventional wave theory. This view dovetails with Hugh Everett’s Many Worlds Interpretation that asserts the objective reality of the universal wave function, in the process denying wave function collapse as propounded in the Copenhagen Interpretation.ĭespite the fact that Schrödinger played a key role in the early development of quantum mechanics, eventually he had serious reservation concerning some of its implications.

The assertion is that there is a universal wave function equivalent to all that is. small-scale – systems, boldly claiming applicability in the macroscopic domain, including the entire universe. The equation goes well beyond describing quantum, atomic and molecular – i.e. In this scheme, the wave function is the most complete and realistic description that can be given to any physical system. Schrödinger’s greatest achievement was the creation of partial differential equations showing that the quantum state of a physical system oscillates on a temporal scale. Here, μ is the particle’s “reduced mass”, V is its potential energy, ∇ sup(2) is the Laplacian differential operator. The second equation applies to a single particle moving in an electric field. Here i is the imaginary unit, ħ is the Planck constant divided by 2π, ∂/∂t indicates a partial derivative with respect to time t, Ψ is the wave function of the quantum system, and Ĥ is the Hamiltonian operator.
