atomic structure and releasing an enormous amount of energy that makes stars hot and bright. Nuclear fusion is an atomic reaction that fuels stars. In fusion‚ many nuclei combine together to make a larger but different element‚ and the result of this process is the release of a lot of energy. Stars are powered by nuclear fusion in their cores‚ mostly converting hydrogen into helium (Fusion in Stars‚ 2012). The production of new elements by nuclear reactions is called nucleosynthesis.

nuclei are split. It is also released during fusion‚ when hydrogen nuclei combine to form a helium nucleus. In fission and fusion‚ nuclear energy produces thermal energy‚ which is given off as heat. Fission’s heat is used to generate electric power in hundreds of locations worldwide. The sun and other stars use fusion to generate radiant and thermal energy. As stars give off energy‚ they lose mass. Someday humans may be able to harness nuclear fusion as well. Nuclear energy also has other uses

may have indeed called very big sticks. Nuclear weapons work by releasing the enormous amounts of energy that are contained in the bonds of atoms. The bonds of atoms can be broken in two ways. The first way is by fission‚ and the second way is by fusion. Fission works by the splitting of atoms with neutrons. To start the reaction‚ though‚ an initial kick of energy is needed. This energy kick usually comes from a conventional explosive (Kroenig‚ “Nuclear Weapon”). Fission weapons work by inducing

Margaret Thatcher once cited.” A world without nuclear weapons would be less stable and more dangerous for all of us.” In the article “Get real: nuclear power is in your future” Allan Kupcis argues that nuclear power is a necessity to maintain “the backbone of any economy.” Thus‚ in our day to days living‚ we seem to ask ourselves about what is meant by the term "Nuclear Energy." Some will give the right concept of the nuclear energy but others will not. It all depends with the knowledge one

Energy: Nuclear Fusion‚ Hydroelectric‚ and Hydrogen Fuel Cells In today’s world‚ where everyone owns an electronic appliance‚ energy is an extremely valuable resource and in high demand. Though in the past this energy was provided by burning fossil fuels such as coal and natural gas‚ this way of providing energy can’t last much longer due to the dwindling amount of fossil fuels and the damage it causes to the environment. Therefore‚ scientists have been searching for new ways of providing energy

The changes that occur during a star ’s life are called stellar evolution. The mass of a star determines the ultimate fate of a star. Stars that are more massive burn their fuel quicker and lead shorter lives. Because stars shine‚ they must change. The energy they lose by emitting light must come from the matter of which the star is made. This will lead to a change in its composition. Stars are formed from the material between stars‚ shine until they exhaust their fuel‚ and then die a predictable

(whose main ideas came in the 1950’s from a group of Russian scientists including Andrei Sakharov and Igor Tamm) constructed with the shape of a torus (or dough-nut) in which a plasma is magnetically confined and heated in order to produce nuclear fusion reactions. The magnetic confinement of the plasma particles in the vacuum vessel torus is obtained through the combination of toroidal and poloidal fields produced by external coils (see fig.I.1) with the additional field produced by the electrical current
