Classical and Quantum mechanics are the two main fields of mechanics in physics. Classical mechanics came a few hundred years before Quantum mechanics. Subsequently it is less accurate and less reliable then the more recent mechanic field of Quantum mechanics. Despite being outdated‚ Classical mechanics can still be used for many everyday problems with bigger and slower moving objects. However‚ when dealing with extremely fast moving or small subatomic particles a Classical approach will not

Quantum physics: The photoelectric effect What is the photoelectric effect? The photoelectric effect is when a clean metal surface emits electrons after light‚ especially ultraviolet‚ has been shone on at it. This happens because of a process called photoelectric emission whereby a single photon package of electromagnetic energy‚ called a quantum‚ is absorbed by metal surfaces. This energy is then transferred to one single electron which can then be released by the metal and that released electron

presented the beginning of his Quantum Theory. Since this time studies have commenced on the nature and behaviour of matter and energy on the atomic and sub atomic level. While it is highly unlikely to see these natures directly without scientific equipment‚ the effects and changes that occur are known as a paradigm shift and can be acknowledged in everyday life. One example of this is the subatomic structure in relation to light. Unlike the newly discovered Quantum theory‚ Newton’s Law studies the

Max Karl Ernst Ludwig Planck was born in Kiel‚ Germany on April 23‚ 1858 (Foundation‚ 2014). He was awarded the Nobel Peace Prize in 1918 and developed what would come to be known as “Planck’s Constant” in quantum theory. During his collegiate years he studied under Gustav Kirchoff‚ who developed Kirchoff’s Law for current and voltages. He suffered a personal tragedy when one of his sons was killed for his participation in an assassination attempt against Adolf Hitler in 1944. Planck’s earliest

Article Review The Quantum Enigma and Islamic Sciences of Nature: Implications for Islamic Economic Theory The Issue The author tries to raise doubts on the validity of the approach taken by neoclassical economics in ‘The Theory of Choice’. The article criticizes the mono-utility function because it is unable to describe a situation with many rational values with a single end‚ which is the basic of Islamic Economy theory. Finally the article points to the Quantum Mechanics‚ to describe the

Introduction The Quantum Theory was the second of two theories which drastically changed the way we look at our physical world today‚ the first being Einstein’s Theory of Relativity. Although both theories revolutionized the world of physics‚ the Quantum Theory required a period of over three decades to develop‚ while the Special Theory of Relativity was created in a single year. The development of the Quantum Theory began in 1887 when a German physicist‚ Heinrich Hertz‚ was testing Maxwell’s

“Leadership is an art of getting someone else to do something you want done because he wants to do it.” Dwight D.Eisenhower. In the majority of companies around the world‚ management is playing a very important role in controlling and keeping everything on its track. A manager is assigned with the power and responsibility to manage a project which can be the key to develop his company. So‚ a manager is sometimes considered as a leader who takes care of managing and leading his team to accomplish

Running head: LEADERSHIP THEORIES AND STYLES Leadership Theories and Styles Shameka L. Evans Indiana Wesleyan University Abstract Since the servant leadership concept was introduced by Robert K. Greenleaf in 1970‚ this style has been adopted by many successful leaders in a variety of contexts. Is servant leadership style right for you? This paper helps to answer that question for many leaders who may be interested in serving others first or in serving rather than being served
