Defense of Neils Bohr
Transcript of Defense of Neils Bohr
The Bohr Model
Shows the atoms as a small, positively charged nucleus surrounded by orbiting electrons
The Defense of Neils Bohr
How was his early life?
What Era(s) did he live in?
What was his Theory? What was his Model?
Who opposed his ideas? Why?
07 December 2013
Born on October 7, 1885 in Copenhagen, Denmark
Bohr's scientific interests and abilities were evidently early, they were encouraged and fostered in a warm, intellectual family atmosphere.
Son of Professor of Physiology and brother of Professor in Mathematics
Attended University of Copenhagen, received doctorate in 1911
Traveled to England and worked under J.J. Thomson, who discovered the electron 15 years previous
Married Margrethe Nørlund in 1912
The late 1930's and 1940's saw Hitler's volatile regime
Bohr focused more on the safety of his fellow scientists over his research
The nucleus of the atom is postively charged and the electrons that surround it are negeatively charged thus giving it a fixed energy that keeps the electrons from falling into the nucleus.
He determine that there was orbits that surrounded the nucleus which he named shells.
For each shell there was a specified number of electrons.
The main person to ever oppose one of Bohr's ideas was the one and only Albert Einstein.
During the conference on the Quantum Mechanical Model, Bohr and Einstein had a huge disagreement.
At this conference, Bohr proposed wave equations described where entities like electrons could be, but the entities didn't actually exist as particles until someone went looking for them.
Einstein proposed that an electron was an electron , and just because someone wasn't looking at it, it was still there wherever "there" happened to be.
Niels Henrik David Bohr was one of the most influential scientists of the 20th century.
Bohr was the first to apply the quantum theory, which restricts the energy of a system to certain discrete values,to the problem of atomic and molecular structure.
He was a major contributor to the development of the quantum mechanical and atomic physics.
Niels Bohr's Life:
Guilty or Not Guilty
Niels Bohr in no way falsified his work.
Bohr came from a very smart family,
His father Christian Bohr was a professor of physiology who inspired him to become professor, along with his brother.
In 1911 he went to New England to study along side J.J. Thomson, another incredibly influential scientist.
Thomson discovered the electron while with Bohr
He taught him every thing he knew.
If Thomson lied about his discoveries, Bohr would have noticed, since he was raised in a high manner.
After things didn't work out with Thomson, Bohr left to learn alongside Ernest Rutherford.
Rutherford had just discovered the atom
Rutherford's idea of the Atomic Theory stated
The atom consisted of a positively charged nucleus
Contained negatively charged electrons orbiting around it.
If Bohr didn't care about science and his work, he would not have improved the theory and would have used the wrong information.
However, Bohr was devoted to his studies and did change Rutherford's original theory.
Bohr fixing the problems with Rutherford's central idea of the Atomic Theory stated that, if orbiting electrons give off energy and eventually are attracted to the nucleus, then the atom would collapse.
He fixed it by stating that in the atom there are orbits of different energy levels around the nucleus that contained a certain number of electrons.
If Bohr went through the trouble of falsifying his work, then why would he go through the trouble of improving other work to make a statement in the science community
All his work was legitimate, thus why he was awarded the Nobel Prize, which he deserved.
Exclusive: Fourth Piece of Evidence
Lost footage of interview conducted with Niels Bohr and fellow physicist Ernest Rutherford
While Bohr attended Copenhagen University in the 1910's, Rutherford had barely discovered the existence of the nucleus
