Nuclear Radiation There are many ways that the movie The Day the Earth Stood Still and the short story "There Will Come Soft Rains" are similar. "There Will Come Soft Rains" by Ray Bradbury is a science fiction story that deals with nuclear radiation and what the future world would be like if there was an atomic bomb. This short story is a good example of what could happen in the future. The Day the Earth Stood Still is a movie that also has the same genre‚ that it is science fiction. It helps

Disadvantage of Technology Hidden camera We have stepped into the 21st century and the world has given us some unbelievable technology that sometimes it seems to be a dream. But when we look at the backside of the latest technology‚ we find that we have made these technologies for our destruction if wrongly used by the wrong people. If the people of the world use these technologies in a right way‚ we all are going to be benefited out of it ‚ but if the motive of a human being is not positive

NUCLEAR ENERGY Nuclear energy is the energy contained in the centre ‚ or nucleus of an atom. The nucleus is the most powerful source of energy that exist. Nuclear energy is use in scientific research and in medicine treatments. It powers satellites and submarines‚ and it is used to produce electricity. People have also put nuclear energy to destructive uses through the creation of weapons.1 Nuclear energy also called ATOMIC ENERGY‚ energy

The change in technology that has taken and continues to take place over time is mind-boggling. 20 years ago the thought of a computer being a necessity would be preposterous but now the thought of not having one is. The advances in technology began with needs for survival but last I heard an iPod is not necessary for daily survival. Is technology moving to fast for us to keep up though? Technology is a problem because we cannot do without it‚ and our use of it clearly makes us both better

Nuclear Energy 1. What is nuclear energy? Text Book Pg 80 2. Nuclear Fission :- In nuclear physics and nuclear chemistry‚ nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei)‚ often producing free neutrons and photons (in the form of gamma rays)‚ and releasing a tremendous amount of energy. The two nuclei produced are most often of comparable size‚ typically with a mass ratio around 3:2 for common fissile isotopes.[1][2].The smallest
