When we look at the life that existed a century back, we realize that things have evolved at an unbelievable rate. The field of science has undoubtedly made a major contribution to this evolution. There have been various scientific inventions that have made life extremely easy over the years. One of these scientific inventions is the telephone. This invention was made by Graham Bell after which vocal communication between two distant people was never a problem. Today, we can never imagine living without light. The bulb was yet another superb invention by Thomas Edison. The television, telescope, projector and various other related scientific inventions undoubtedly hold the highest importance levels.
We have had a lot of blessings of science in the modern era as well. Gadgets like tablets, laptops, smartphones are related examples of these inventions. The sewing machine is one of the blessings of science that is not given a very high level of importance by a lot of people. This invention has helped the human race in designing some of the best clothes and apparel. One of the most important blessings of science is medicine. Today, doctors around the world have designed a cure for fatal diseases like cancer, tumor, and leukemia due to medical science. Through x Rays, signs of complicated medical problems become completely apparent. Thus, the x-ray machine can also be termed as an important invention.
Along with the positive effects, science has also had its negatives. In other words, you cannot ignore the hazards of science in any manner. War weapons can be termed as a key example. With so many scientific advancements, war weapons have become more horrendous. Due to advancements in technology, it has become quite easy to eliminate an entire nation in days. The key issue is that people do not take the hazards of science in a serious manner. This is because they have become quite dependent on the on the luxuries that these inventions have brought along. The chances of nuclear war have increased. As the weapons of destruction have become more intense, countries have started to invest higher sums of money on these weapons. One of the other hazards of science is the increase of radiation in various forms causing cancer. For instance, microwave oven and the cell phone are two key scientific inventions which have benefitted the human race. However, both these devices emit harmful radiations which cause cancer. Today, people of all age groups are dependent on these gadgets which increase the chances of getting infected with diseases like cancer. Scientific inventions like gaming have reduced the level of physical activity in children.
