When the nucleus of an atom splits or when two nuclei of different atoms combine, a large amount of energy is released in the form of heat and radiation. Their energy is termed as Nuclear Energy. Nuclear processes are used in order to generate heat or electricity from nuclear energy. These nuclear processes are performed using the earth elements. During these processes the nuclei of atoms either join together which is called fusion or they break apart which is called fission.
A physicist’s job is to use humanity’s understanding of how matter and energy interact to learn about the Universe. The job of physics, however, is to unite the four fundamental forces of nature: Gravity, Strong and Weak Nuclear, and electromagnetism, into a single physical model; A theory of everything. In the 20th century, physicists revolutionized humanity’s understanding of these forces and made great strides in uniting them, but the two theories which have brought humanity the closest to this unified field theory, the theories of general Relativity, and Quantum Mechanics, cannot seem to coexist. Both of these theories have made immense contributions to science, but unless physicists can find a way to unite these two scientific principles
Nuclear physics is the study of the relationship between the nuclei of atoms. For nuclear physics to be applied in real life situations, radioisotopes are often used. These are isotopes that have an unstable protons to neutrons ratio that causes them to spontaneously undergo radioactive decay. They do this in order to change their amount of protons and neutrons and become a stable isotope of the same or a different element. To do this, they can either go through alpha decay or beta decay and depending on which one it does, it will either emit alpha particles or beta particles which will cause it to end up with a different element or isotope.
This thesis seeks to explain the assumption of the being theory and also highlighting contemporary theories in support of it. The Big Bang theory can be viewed as a concept of cosmology by nature. It assumes that the universe originated from a period of ten billion to twenty billion years ago. The universe is said to have originated from a cataclysmic explosion of small volume matter at extreme density and temperature. Cosmology can be viewed as the study of the origins, evolution and structure of the universe.
What is the periodic table: Our world is composed of many things. And these many things are composed of many other things. Everything on our earth is made of the elements of the periodic table (our earth is immense, imagine how important elements are!). Elements are substances that can’t be broken down or made into anything simpler by chemical reactions. The periodic table and its elements are both vital parts of chemistry and other sciences.
The history of thermodynamics is a fundamental strand in the history of physics, the history of chemistry, and the history of science in general. Owing to the relevance of thermodynamics in much of science and technology, its history is finely woven with the developments of classical mechanics, quantum mechanics, magnetism, and chemical kinetics, to more distant applied fields such as meteorology, information theory, and biology (physiology), and to technological developments such as the steam engine, internal combustion engine, cryogenics and electricity generation. The development of thermodynamics both drove and was driven by atomic theory. It also, albeit in a subtle manner, motivated new directions in probability and statistics; for example,
He went to the University of Vienna, where he focused mainly on the study of physics and was strongly influenced by Fritz Hasenöhrl. In 1910, he graduated with a PhD in physics. Afterwards, Schrödinger experimented in the field of atmospheric radioactivity, electrical
Philosophers and General people have come up with many theories, in an attempt to explain the origins of the earth. They have tried to come up with models which try to explain how the earth came into being, and its future. One of the popularly known theory is the Big Bang theory, which presupposes that for the universe to originate ,all matter that we know was contained in a tiny speck which went on to explode. The theory continues to develop and evolve from the time it was conceptualized. Scientists have taken part in contribution to this.For a long time now people have upheld various ideas of what the universe is like, from the Aristotelian to the Copernican universe among other ideas.
By the time of the Industrial Revolution, people used water energy, heat energy and nuclear power. Using nuclear power has spread to most countries in the world because scientists are looking at it as a real renewable source for energy. Nuclear power is the power that is produced by controlling the reaction of separating the element such as Uranium. However, when it was used to make weapons such as nuclear bombs some of its negative effects appeared after the Second World War. Also when the Chernobyl Reactor accident happened, the reactor was destroyed and a cloud of radiation spread to a huge area in Europe.
By Lo Kwun Hin , Jordan Dr. Bernard L. Cohen,(1990) an Professor Emeritus of Physics and of Environmental and Occupational Health at University of Pittsburgh. He mention that the major advantage of nuclear power is that avoiding the problems of fossil fuels including coal, oil and gas. He also mention that the using of fossil fuels from human activity can cause three major problems : global warming, acid rain and air pollution, which totally affected the environment. (cited in Dr. Bernard, 1990, para. 1) Dr. Bernard also indicate another advantage of nuclear power, is the nature of the fuel consumed.
