JOSEF ALEXANDER

SCHRÖDINGER

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.

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.

In 1938, he began to work at Institute for Advanced Studies in Dublin.

In 1956, he returned to Wien.

In 1961, he died.

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.

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.

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.

These subshells can be subdivided into orbitals.

Each orbital is a distinct region. Each orbital can contain max. 2 electrons. He generated an equation:

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.

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:

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.

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
