From the discovery of penicillin to the artificial sweetener in our drinks, accidental discoveries have had major impacts on our lives. T. C. Hsu's accidental discovery that mitotic cells washed with hypotonic solution can be easily squashed to visualize the chromosomes is now an important scientific technique for cytological studies. Throughout history there have been many cases of scientists who have set out to investigate one thing but instead make incredible "accidental" discoveries of another. Two examples are the discovery of penicillin, the first antibiotic, and the discovery of saccharin, an artificial sweetener. Even though it might have been luck that had brought the scientists to see an observation, it was genius that made them realize that it was a discovery.

One of the most major positive effects of the discovery of the atom is that by splitting atoms of radium in a nuclear power plant, we can gain a lot of energy. However, the waste produced in this process is very toxic and can damage us badly.......... Also, the nuclear bombs produced using these theories are very deadly.
