Timeline Project- History of Communication Drawings: Cave paintings are paintings found on cave walls and ceilings‚ and especially refer to those of prehistoric origin. The earliest such art in Europe dates back to the Aurignacian period‚ approximately 40‚000 years ago. Evidence suggests that they were not merely decorations; they speak of stories and things that may have happened in their life. Also surprisingly nearly 340 caves have now been discovered in France and Spain that contain art from

CJ121 – Corrections 14 JUL 2010 Corrections Timeline This narrative will illustrate a timeline depicting four eras within the correctional system of America. The eras that I will be discussing are: 1800‚ 1920-1950‚ 1990‚ and 2000’s. For each era‚ the following items will be described: the history and development‚ treatment and punishment of the offenders‚ the description of the holding and monitoring of the offenders. The conclusion will discuss the alternatives to incarceration and the influences

The Rutherford Model of the Atom 1. In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge‚ surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2. The apparatus

INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

Jazz Timeline (1900-1955) Roots of Jazz: It had blend elements of several cultures. First‚ West African emphasis on improvisation‚ percussion and call-and –response techniques. Second‚ American brass band influence on instrumentation. Third‚ European harmonic and structural practice. Blues and Ragtime were immediate source. Ragtime: Ragtime piano music is generally in duple meter and is performed at a moderate march tempo. The pianist’s right hand plays a highly syncopated

My topic is the atomic bomb. Two questions I have are one‚ why did the atomic bomb happen? Two‚ how did the atomic bomb change the world? The sub-topics introduce the Manhattan project. Japan refused to surrender‚ why the United States dropped an atomic bomb on Hiroshima and Nagasaki? The atomic bomb was first used in warfare at Hiroshima and Nagasaki in august 1945‚ and the bomb played a key role in ending World War II. The Atomic bomb created the Manhattan project. The Manhattan

Atomic energy By: Hiram A. Murray III Background info The origin of the phrase atomic energy check in from the years of 1905-10. It is defined as energy released by reactions within atomic nuclei‚ as in nuclear fission or fusion. Now a days it is referred to Nuclear energy. Nuclear power uses fission (splitting atom nuclei) to produce energy. Atom nuclei is also none as the nucleus (center of the atom). Around 6% of the world’s energy and 14% of the world’s electricity is produced by nuclear

the Atomic Mass # differ from the Atomic #? The atomic mass differs from the atomic number by the fact that the atomic mass is composed of the total number of protons and neutrons in the nucleus‚ and the atomic number is the number of protons found in the nucleus‚ and is identical to the charge of the atom. 3) What is an isotope? Give an example (show how it is an isotope). An isotope is a form of the same atom that differs from the original atom in atomic mass
