PRESENTATION OUTLINE

Robert Milikan

March, 22nd 1868 to December,19th 1953

Robert's Background

  • Robert was bron March,22nd 1868 and died December,19th 1953
  • His Grandparents were part of the New England stock.
  • Robert gained most of insights about Electrons in Germany
  • The Universities in Germany where he studied were University of Berlin
  • He also then transferred to the University of Gottingen.

mILLIKAN'S dISCOVERIES

  • Some discoveries were specifically in the fields of electricity.
  • He also specialized in Molecular Physics as well.
  • His earliest success was the accurate determination of Electrons. 
  • He surrounded himself with information dealing with electrons.

How Millikan Specifically dealt with the electron

  • He measured the charge of an electron in his famous oil-drop experiment.
  • He also verified Einstein's prediction of the relationship between 
  • light frequency as well as electron energy in the photoelectric effect.
  • After utilizing and discovering these two new discoveries, he recieved
  • the nobel peace prize in 1923 in his discoveries in the physics field.

What is the pHOTOELECTRIC EFFECT?

  • The photoelectric effect is the observation that many metals emit electrons
  • when light comes upon them.  Electrons in this case are considered and may
  • be called photoelectrons.
  • Robert Millikan was very familiar with this theory.

Why was Mr.Millikan so famous?

  • He was one of the man helpers in discovering modern day Astronomy.
  • He opened up the doors for more discoveries in the electron fields.
  • His Oil-Drop experiment proved was able to determine the accurate charge 
  • of an Electron
  • Christianity was very important to him dealing with evolution and biblical.

Summary of Millikans life

  • Throughout his life he remained an avid journalist and author and 
  • contributed many pieces to scientific journals.
  • His most important achievement naming "Cosmic Rays."
  • "Cosmic Rays", are highly energetic atomic nucleus or a different particle 
  • traveling at a speed of which is approaching the speed of light.
