Erwin Schrödinger: His Life And Work.

If Quantum Mechanics has travelled so far today, it wouldn't have been possible without contributions from some of the finest minds in the history. And, Erwin Schrödinger, better known as the Father of Quantum Mechanics is one such mind. Today, on the eve of his 132nd birth anniversary, let's try to dig a little deeper into the life of this genius

Early life and Education:

Erwin Rudolf Josef Alexander Schrödinger was born in Austria’s capital city, Vienna, on August 12, 1887. His father Rudolf Schrödinger wss a botanist. While, his mother Georgine Bauer was the daughter of a chemistry professor. Erwin was a gifted child. He learnt English and German at home as both were spoken in the household. He didn't go to elementary school, rather he received lessons at home from a private tutor up to the age of ten. In 1898, He entered the Akademisches Gymnasium.

Higher education and Career:

Erwin joined University of Vienna for higher studies. Here, he focused primarily on the study of physics and got strongly influenced by another young physicist, Fritz Hasenöhrl. Schrödinger graduated with a Ph.D. in physics in 1910. Afterward, he worked for a few years at the institution as an lab assistant. However, in 1914, the government drafted him into World War I where he served with Austro-Hungarian military forces in Italy as an artillery officer. After returning back, he took on a number of faculty and staff positions at various places. These include the University of Stuttgart, the University of Jena and the University of Breslau. Eventually he joined the University of Zurich in 1921 where the wonders were waiting for him!

The Equation of Life:

Erwin Schrödinger's tenure as a professor at Zurich over the next six years proved to be one of the most important periods of his physics career. Here, he became fascinated by the new idea that electrons could behave both as particles as well as waves. Aroused by his curiosity, he published a paper on the same in 1926. In this paper, he derived a new equation, now known as the Schrodinger Wave equation. This equation described how systems with wave-particle duality, like electrons, change over time. This was a remarkable accomplishment of it's time. And, is still one of the most important milestone in the history of quantum mechanics. This equation was termed as the "Equation of Life" by Richard Feynman.

It gave the correct energy eigenvalues for the hydrogen-like atom. Without any doubt, this paper has been universally celebrated as one of the most important achievements of the twentieth century. It created a revolution in quantum mechanics, and indeed of all physics and chemistry. In the coming years, three more papers were published in this series. These papers were undoubtedly the central achievement of his career.

Schrödinger's cat :

In 1935 Schrödinger published a three-part essay on “The present situation in quantum mechanics”. In order to make it easily understandable to people, It contained a purely hypothetical thought experiment. It says that imagine there's a cat is in a box with a source of poison gas. That gas would be triggered (or not) by the decay of one electron in one direction or another. Now, Because of the uncertainty of the electron’s behavior, there exists a moment in time when the observer is unsure whether the cat is alive or dead, and in some sense, it’s both!

What is life?

In 1944, Schrödinger published his book named "What is Life?".Although, it wasn't entirely original. But it had a profound effect on the future of genetics and molecular biology. Schrödinger wrote that the gene was an aperiodic crystal, a code script for life. His book inspired a number of scientists. These include three of the main players in the discovery of DNA’s structure – Francis Crick, James Watson and Maurice Wilkins.

Other contributions:

Apart from being recognized as the father of Quantum Mechanics, Erwin Shrödinger has also authored many works in various other fields of physics. These include his work in areas of statistical mechanics and thermodynamics, physics of dielectrics, colour theory, electrodynamics, general relativity, and cosmology. He also made several attempts to construct a unified field theory.

Award and Honours:

For his experimental work on radioactivity of the atmosphere, Schrödinger received the 1920 Haitinger Prize of the Austrian Academy of Sciences.n 1933, Schrodinger won the Nobel Prize in physics for his groundbreaking equation together with Paul Adrien Maurice Dirac. He also received the Max Planck Medal in 1937.

Erwin Schrödinger is truly one of the finest examples of genius minds this world has witnessed till date. Without any doubt, Schrödinger is the ''father of quantum mechanics''. Happy Birthday, Erwin.
