Where did this guy come from?
• Otto was born in Zary, Poland… formerly known as Sohrau, Germany
![Page 3: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/3.jpg)
How did Otto get so smart?!
• Otto attended high school in Breslau, Germany after moving there with his parents
• After high school, Otto continued his education at the University of Breslau in 1906
• Just six years later he graduated with a Ph. D in physical chemistry
![Page 4: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/4.jpg)
Hanging with our pal Einstein…
• Following Otto’s graduation he joined Einstein at the University of Prague… and again, followed him to the University of Zurich
![Page 5: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/5.jpg)
While at the University of Zurich…
• Otto became the lecturer of Physical Chemistry at the Swiss Federal Institute of Technology in 1913.
![Page 6: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/6.jpg)
Working with Al…
• During his time with Einstein they wrote a 1913 paper together on the zero-point energy of a harmonic oscillator.

Quickly changing…
• In 1914 Stern relocated to the University of Frankfurt am Main as lecturer of Theoretical Physics, remaining there until 1921
• Slightly interrupted by serving in the Military…1914-1918
![Page 8: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/8.jpg)
Getting the Professor title…
• In 1921 Stern was finally named a Professor at the University of Rostock in 1921…
• Soon after he left in 1923 to work at the newly founded Institute of Physical Chemistry at the University of Hamburg
![Page 9: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/9.jpg)
Driven from home…
• Stern, being Jewish, left Germany when the Nazi regime took power in 1933…
• Thus landing him in the United States to continue his work
![Page 10: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/10.jpg)
Coming to America ….
• Once in the United States, Stern was named Research Professor of Physics at the Carnegie Institute of Technology
• Later earning professor emeritus (retired but with an honorary title) in 1945 at the University of California, Berkeley
![Page 11: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/11.jpg)
Why do we care about Stern?
• For his help in the development of the molecular ray method and for his discovery of the magnetic moment of the proton
![Page 12: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/12.jpg)
Molecular ray method…• Stern and Walther Gerlach experimented with
molecular-beams Hamburg in the early 1920s.
• They conducted the experiment by shooting a beam of silver atoms through a nonuniform magnetic field onto a glass plate
The beam separated into 2 beams, confirming the space quantization theory, that atoms can position themselves in a B field in only in a few directions (2 for Silver), as
opposed to any direction, like we thought from classical physics
![Page 13: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/13.jpg)
Magnetic Moment of the proton…
• Stern discovered the magnetic moment (strength of a subatomic particle’s magnetic property) of the proton by using a molecular beam, from his original experimenting
• He established that it was really about 2 1/2 times the theoretical value.
![Page 14: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/14.jpg)
One last contribution…
• Stern contributed in the discovery of spin quantization while working with Gerlach on the magnetic moment of a proton
• He was not recognized with the Nobel Prize for this award, but I recognized this when we studied the angular momentum of electrons
![Page 15: OTTO STERN February 17, 1888 - August 17, 1969](https://reader037.vdocuments.mx/reader037/viewer/2022110102/56813f16550346895da9a815/html5/thumbnails/15.jpg)
What did he get for all of his hard work?!
• Stern was awarded the 1943 Nobel Prize in Physics
• Fun facts… He was the first person awarded since 1939, he was the only person to receive a Physics award for the year, and the committee held his award for one year. He officially received his reward in 1944.
