nuclear physics?

Question

What are some of the benefits/dangers of nuclear engery in our society, mainly focusing on nuclear bombs. Please give detailed answers and some physics lingo too. thanks guys!

Answer 1

Nuclear physics is the work dealing with the centre of atoms. I like to tell people that the greatest number in the universe is the number two. In nuclear physics the two is fission and fusion. Fission is the process of splitting atoms, uranium and already heavy elements. While fusion is the joining of light elements such as hydrogen. The sun, which supplies us with light and heat is an example of fusion. The power plants that use uranium are examples of fission. Splitting atoms leaves one with often radio toxic exhaust materials. While the fusion process is responsible for all the elements in the universe heavier then hydrogen, as the universe was thought only to contain hydrogen in the early times. The danger with fission is that it can harm you without requiring direct contact. Uranium can be made to give massive explosions, or a slower reaction to give off heat to power a stream turbine. Fusion, is the process in all the stars of the heavens, that make them shine. The best benefit I can see in nuclear physics is the possibility of getting water from space. Taking hydrogen and fusing four nuclei with result in energy and helium. (1.00797 to 4.0026 and energy) repeating the process with the four new helium nuclei with result in an element of about 16. Oxygen is around 15.994. Then all one does is to "burn" additional unprocessed hydrogen with the processed oxygen to give one a nice cooking flame and water vapor which can condensed else were aboard a space craft. SUMMARY fission bad, dirty and toxic. fusion good, clean and healthy.
Footnote, fusion WILL enable us to travel between stars, but it seems no one wants to go!

Answer 2

Energy: safer in the sense of way fewer deaths, historically, amongst nuclear workers than coal miners, but more dangerous in the sense that catastrophic failure of a nuclear plant is more dangerous than a coal-fired station.
Energy: safer in that greenhouse gases and air pollution do not result, dangerous in the sense that radioactive waste must be stored for thousands of years
Bomb: dangerous in the sense that if a large nuclear exchanged occurred, civilization could collapse, or humans become extinct.

Answer 3

Hi. Nuclear energy and nuclear bombs are separate entities. The energy aspect has benefits and disadvantages. The benefits include power without short term environmental impacts ( no carbon emission). The disadvantages are long term storage of the leftover fuel waste and reactors. I think the 'bomb' issues are obvious.

Answer 4

I think you should go to either Google and/or Wikipedia and look this information up for yourself. It's totally easy to find, and there are butt-loads of info on this topic, and all it takes is you sitting down for a short while and doing the work for yourself.

Most anyone else here will throw websites at you anyway.
