1906 Hans Geiger Developed an electrical device to "click" when hit with alpha particles. 1909 R.A. Millikan Oil drop experiment determined the charge (e=1.602 x 10 -19 coulomb) and the mass (m = 9.11 x 10 -28 gram) of an electron. 1911 Ernest Rutherford Using alpha particles as atomic bullets, probed the atoms in a piece of thin (0.00006 cm) gold foil. He established that the nucleus was: very dense, very small and positively charged. He also assumed that the electrons were located outside the

The meaning behind the character of Rutherford Selig Author and playwright August Wilson’s Century Cycle, a series of ten plays representing the lives of African-Americans during each decade of the twentieth century, has widely been acknowledged by critics as well as the general public for its accurate depiction of the journey and struggles of the African-American community in its search for an identity in a white world. During the entire cycle Wilson almost exclusively focuses on black characters

chocolate chips. The ice cream represents positive charged atoms and the chocolate chips are negative charged atoms.” “Brilliant Phoebe, he also discovered that there was negative charges in atoms called electrons.” Ms. Frizzle responded. “Ernest Rutherford was another person who conducted an experiment, it was called the gold foil experiment.” Ms. Frizzle added. “Oh I've heard about that one,” Arnold said, “he fired a ray of alpha particles at a sheet of gold foil, a few of the particles were deflected

Rutherford B. Hayes was born on October 4,1822 in Delaware,Ohio. His mom’s name was Sophia Birchard Hayes. Since, Rutherford B. Hayes was the youngest one out of his four siblings, he was the most precious to his mother. His father’s name was Rutherford Hayes Jr. He was a storekeeper and died ten weeks before Rutherford B. Hayes was born. Hayes attended Kenyon College in 1842. Later on, he set off to go to Harvard Law School and eventually graduated in 1845. He had five years of law practice which

One Saturday morning, down the old dirt road came a dirty black pickup. Within this vehicle sat Doctor Rutherford Bentson, science professor. as he typically did on weekends like this. The pickup approached the end of the road, and the car approached to a stop in front of a dead tree. The worn seat was relieved of its pain when Bentson climbed out of the driver side door. Bentson let out a sigh, as he gathered his tools. It was not often that he was able to come out to this part of the swamp. This

Rutherford B. Hayes Born on October 4, 1822 Rutherford Bircher Hayes, called "Ruud" as a child, was named for his father and grandfather. His American roots traced back to 1680's New England. Five years before Ruud’s birth, his parents fled the poor economy there and resettled in Delaware, Ohio, just north of Columbus. They secured a farm, established a whiskey distillery, and built a house in town. But Ruud’s father died in July 1822, leaving Sophia Bircher Hayes—already mourning the recent loss

Sodium is one of the most well known and abundant yet fascinating elements on the periodic table. Sodium was given its name after a chemist who electrolytically produced a heretofore unknown element from molten soda. This gave him the new element that he named sodium after the word soda which is the collective name for several forms of sodium carbonate. The word “soda” likely came from the Arabic word “suda” which means headache. This element has eleven protons, eleven neutrons, and no electrons

As stated above, The book I chose to do for the book report is called “Disasters and Democracy”. It was written by Rutherford H. Platt in 1999. Rutherford Platt is an urban writer and lecturer from Massachusetts. He is also professor emeritus of geography at the University of Massachusetts, a faculty associate with the lincoln Institute of Land policy, and he is also a scholar with the Penn Institute of Urban Research. He also holds degrees from Yale, and University of Chicago. This book addresses
