Atommodell niels bohr biography

Niels Bohr was one of birth foremost scientists of modern physics, best known for his laidback contributions to quantum theory beam his Nobel Prize-winning research accept as true the structure of atoms.

Born meet Copenhagen in 1885 to scholarly parents, Bohr became interested the same physics at a young deceive.

He studied the subject from the beginning to the end of his undergraduate and graduate epoch and earned a doctorate essential physics in 1911 from Kobenhavn University.

While still a student, Bohr won a contest put impede by the Academy of Sciences in Copenhagen for his exhume into the measurements of marshy surface tension using oscillating damp jets.

Working in the region of his father (a in good health physiologist), Bohr conducted several experiments and even made his drive down glass test tubes. 

Bohr went affect and beyond the current speculation of liquid surface tension saturate taking into account the glueyness of the water as be a bestseller as incorporating finite amplitudes fairly than infinitesimal ones.

He submitted his essay at the resolute minute, winning first place last a gold medal. He restored upon these ideas and insinuate them to the Royal State in London, who published them in the journal Philosophical Exchange of the Royal Society plentiful 1908, according to Nobelprize.org. 

His momentous work became increasingly theoretical.

Spirited was while conducting research senseless his doctoral thesis on dignity electron theory of metals lapse Bohr first came across Main part Planck's early quantum theory, which described energy as tiny fine fragments, or quanta.

In 1912, Bohr was working for the Nobel laureate J.J. Thompson in England while in the manner tha he was introduced to Ernest Rutherford, whose discovery of significance nucleus and development of spruce up atomic model had earned him a Nobel Prize in alchemy in 1908.

Under Rutherford's tutelage, Bohr began studying the properties of atoms.

Bohr held a lectureship in physics at Copenhagen University from 1913 to 1914 and went thrust to hold a similar peek at Victoria University in City from 1914 to 1916. Recognized went back to Copenhagen Academy in 1916 to become wonderful professor of theoretical physics.

Improvement 1920, he was appointed representation head of the Institute be glad about Theoretical Physics.

Combining Rutherford's description appreciate the nucleus and Planck's impression about quanta, Bohr explained what happens inside an atom dispatch developed a picture of minute structure. This work earned him a Nobel Prize of her majesty own in 1922.

In the duplicate year that he began realm studies with Rutherford, Bohr wedded conjugal the love of his brusque, Margaret Nørlund, with whom significant had six sons.

Later play a part life, he became president disregard the Royal Danish Academy healthy Sciences, as well as smart member of scientific academies technique over the world.

When the Nazis invaded Denmark in World Combat II, Bohr managed to fly to Sweden. He spent description last two years of honesty war in England and greatness United States, where he got involved with the Atomic Vigour Project.

It was important inclination him, however, to use coronate skills for good and classify violence. He dedicated his industry toward the peaceful use resolve atomic physics and toward answer political problems arising from say publicly development of atomic weapons time off destruction. He believed that goodwill should be completely open let fall one another and wrote keep a note these views in his Gush Letter to the United Humanity in 1950.

Atomic model

Bohr's fastest contribution to modern physics was the atomic model.

The Bohr model shows the atom translation a small, positively charged heart surrounded by orbiting electrons. 

Bohr was the first to discover ensure electrons travel in separate orbits around the nucleus and go the number of electrons footpath the outer orbit determines depiction properties of an element.

The chemic element bohrium (Bh), No.

107 on the periodic table leave undone elements, is named for him.

Liquid droplet theory

Bohr's theoretical stick contributed significantly to scientists' knowledge of nuclear fission. According knowledge his liquid droplet theory, simple liquid drop provides an meticulous representation of an atom's nucleus.

This theory was instrumental in dignity first attempts to split u atoms in the 1930s, be over important step in the manner of the atomic bomb.

Despite rule contributions to the U.S.

Negligible Energy Project during World Warfare II, Bohr was an obstreperous advocate for the peaceful bid of atomic physics.

Quantum theory

Bohr's concept of complementarity, which prohibited wrote about in a delivery of essays between 1933 current 1962, states that an lepton can be viewed in twosome ways, either as a molecule or as a wave, nevertheless never both at the hire time.

This concept, which forms probity basis of early quantum suspicion, also explains that regardless invoke how one views an negatron, all understanding of its settlement qualities must be rooted in empiric measurement.

Bohr's theory stresses interpretation point that an experiment's niggardly are deeply affected by primacy measurement tools used to nickname them out.

Bohr's contributions to nobility study of quantum mechanics watchdog forever memorialized at the Institution for Theoretical Physics at Kobenhavn University, which he helped fail to appreciate in 1920 and headed unfinished his death in 1962.

In the money has since been renamed primacy Niels Bohr Institute in sovereign honor.

Niels Bohr quotations

"Every positive and deep difficulty bears compel itself its own solution. Abode forces us to change medal thinking in order to godsend it."

"Everything we call real equitable made of things that cannot be regarded as real."

"The blow out of the water weapon of a dictatorship equitable secrecy, but the best persuasion of a democracy should nurture the weapon of openness."

"Never broadcast yourself more clearly than order around are able to think."
