Mottelson was born in Chicago, Illinois. He graduated from Lyons Township High School in LaGrange, Illinois. He received a Bachelor's degree from Purdue University in 1947, and a Ph.D. in nuclear physics from Harvard University in 1950.
In 1950–51, James Rainwater (1917 – 1986) and Aage Bohr (1922 – 2009) had developed models of the atomic nucleus. It began learn the behaviour of the individual nucleons. Mottelson worked with Aage Bohr to share the theoretical models with experimental data.
In three papers which were published in 1952–53, Bohr and Mottelson demonstrated close agreement between theory and experiment, for example showing that the energy levels of certain nuclei could be described by a rotation spectrum. This work stimulated new theoretical and experimental studies.
Rainwater, Bohr and Mottelson were jointly awarded the 1975 Nobel Prize in Physics "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection".
Bohr and Mottelson continued to work together, publishing a two-volume monograph, "Nuclear Structure". The first volume, "Single-Particle Motion," appeared in 1969, and the second volume, "Nuclear Deformations," in 1975.
Professor Mottelson is a member of the Board of Sponsors of The Bulletin of the Atomic Scientists.
He is a foreign fellow of Bangladesh Academy of Sciences and the Norwegian Academy of Science and Letters. In 1969, he won the Atoms for Peace Award.

Isan language
Isan is the name for a number of closely related dialects which are spoken in the Northeast of Thailand and neighbouring countries. Isan is mostly used for informal communication. Isan consists of a number of dialects, there is no official language. People who speak one dialect usually understand the others. When Isan is written down, the Thai alphabet is used most of the time. Very rarely, the Lao alphabet, which is also used to write the Laotian language is used. About 20 million people speak the Isan language as their first language. About a third of the population of Thailand, and 80% of the speakers of Laotian understand it.
Pierre-Joseph Redouté
Pierre-Joseph Redouté (10 July 1759 in Saint-Hubert – 19 June 1840 in Paris) was a painter and botanist from the Southern Netherlands. He is known for his watercolours of roses, lilies and other flowers. He was nicknamed "the Raphael of flowers" and has been called the greatest botanical illustrator of all time. Many of the species he painted had never been illustrated before.
He was an official court artist of Queen Marie Antoinette, and he continued painting through the French Revolution and Reign of Terror.
For fifty years, Redouté was the drawing teacher to French queens and princesses. He dedicated "Choix des plus belles fleurs" to two of his students, Louise and Marie d’Orléans. Later, Marie d’Orléans became the first queen of the Belgians.

Sherman's March to the Sea
Sherman's March to the Sea is the name given to the military Savannah Campaign in the American Civil War. This was a march of troops through Georgia that lasted from November 15 to December 21, 1864. It was led by Maj. Gen. William Tecumseh Sherman of the Union Army.
The campaign began with Sherman's troops leaving the captured city of Atlanta, Georgia, on November 15. It ended with the capture of the port of Savannah on December 21. His army burned military targets along with stores, other businesses, and the homes of the people who lived in their path. This ruined the Confederacy's economy and its means of travelling.
