Science is our power as human beings to use our wisdom and make decisions.
When a loved one is dying of cancer, what would you do? Would you not do anything possible to try to help them? Here is where science has a role in our lives; when we want to do something otherwise difficult or impossible. Though the ways of learning science has changed over the years from solely thinking logically to reading classics to experimenting, the way scientific knowledge is used has not been changed. When there is an epidemic, medicine is used to carry out man's will to cure it. When the Egyptian pyramids were to be built, architecture came into use.
Yet science is not used only for such needful or elaborate situations. They also appear in our daily lives. We know it is important to wash ourselves regularly, only for biology. The Wright brothers were able to invent the airplane because they knew hot air rises, and since then, we have been able to use their technology to travel great distances in short periods of time.
We humans would be so impotent without science. Science is our knowledge of the universe. It is natural to have for a being who thinks. If we did not have science, it would mean we are plain animals motivated purely by instinct. Our definition of "life" as a human would not exist. Great are the blessings of science.
However, our wisdom is not complete, and can lead us to do wrong. Thereupon, science can be a curse. We have changed the passenger airplane into a fighter. Cameras for keeping memories spy on people. Cell phones for conversations are used to bully kids around, and even explode trains. Our greed, hatred, fear, wickedness, and stupidity have produced terrible uses of what our scientific knowledge has put together. As we all know from Spiderman, "With great power comes great responsibility."
Science gives us options to do or not to do. Though each option has its consequences, it is a distinct strength which evidently separates us from animals. How we use it will greatly influence the lives of each one of us.
