2. BIOGRAPHY  Borned on August 12, 1887, in Wien.  The only son of well-educated parents.  He attended the University of Wien.  PhD in physics and a position with the university.  A chair in theoretical physics at the University of Zurich in Switzerland in 1921.

3.  In 1926, he published the wave equation that he created.  In 1927, he began to work at University of Berlin.  In 1933, he began to work at Oxford University and share the Nobel Prize with Paul Dirac.

4.  In 1938, he began to work at Institute for Advanced Studies in Dublin.  In 1956, he returned to Wien.  In 1961, he died.

5. Schrödinger’s Atomic Model  Electron arrangement around the nuclei of atoms.  The electron is a wave.  An electron can be found in a given region of space at a given time.  This model tells us where the electron might be.

6.  Later, he did the Schöringer’s cat thought experiment to explain it.  Schrödinger's model allowed the electron to occupy three-dimensional space.  The principal (n), angular (l), and magnetic (m) quantum numbers.

7.  Each electron shell is made up of a number of subshells.  The number of subshells in a shell is the same as the shell number.

8.  These subshells can be subdivided into orbitals.  Each orbital is a distinct region.  Each orbital can contain max. 2 electrons.  He generated an equation:

9.  The first person to write down such a wave equation.  Shows all of the wave like properties of matter and was one of greatest achievements of 20th century science.  Used in physics and most of chemistry to deal with problems about atomic structure.

10. Schrödinger's Cat  On June 7 of 1935, he published the Schöringer’s cat thought experiment that is the most famous paradoxes in quantum theory:

12.  The cat's fate is tied to the wave function of the atom.  The atom is in a superposition of decayed and undecayed states.  Thus, the cat must itself be in a superposition of dead and alive states.

13.  This experiment is called quantum indeterminacy or the observer's paradox.  The observation or measurement itself affects an outcome.  There is no single outcome unless it is observed
