The core principles upon which science is founded comprise of curiosity to the surroundings and the need to understand the workings of nature and human behaviour through observation, testing and recording. In today’s living, it is often that one forgets the strides that have been taken in the advancement of science and the benefits upon which human living has eminently improved. This paper seeks to outline some of the contributions of science in human life and whether the contributions are beneficial in the everyday lives of human beings.

  1. Antibiotics

To start with, the most significant contribution of science in human life is modern medicine practices. Modern medicine such as the antibiotics have greatly impacted human living as diseases such as Malaria which were once fatal illnesses are now curable without much constrain.  From the discovery and production of Penicilin by Dr. Alexander Flemming, modern medicine practices have become instruments deemed to make human life better. Since then, many renowned scientists from all over the world including Dorothy Crowfoot Hodgkin, Dr. Howard Florey and Andrew J Moyer, to mention a few, have built up on the discovery so as to create better and more efficient ways to deal with harmful bacteria and diseases in human beings (Brown, 2013). Science is an unquenchable thirst for the secrets within nature. As such, science is on a never ending quest to discover solutions to human deficiencies and diseases so as to make life easier for human beings. Discoveries of new ways to combat viruses and prevent disease is one of the greatest contributions of science to human life.

  1. The ‘Germ Theory’

The “Germ Theory” is among the most crucial scientific discoveries that are applied in human life. The theory established by Louis Pasteur reveals how fermentation occurs in food substances with the help of microbes. Through the theory, better hygienic practices were encouraged resulting to less transmission of infectious diseases. As a result, he contemplated the boiling of milk until ultimate temperature so as to eliminate microbes which is known as “Pasteurization” and is used in food manufacturing plants to this day. The theory facilitated various discoveries such as the notion of antibodies which is applied in techniques used to diagnose diseases (Geison, 2014).

  1. Organ transplant

Science has benefited mankind through the discovery of organ transplants. Originated by Dr. Joseph Murray in 1954 where he removed a kidney from patient and transplanted the said kidney to another patient in the attempt to save the patient’s life. The action, however crude, was later advanced through development of drugs which are applied in a patient getting an organ to temporarily flatten their immune system long enough for the organ transplanted to assimilate into the system. This has been made useful in the medical field as many people around the world are able to receive organ transplants which save their lives and make their lives better. Thanks to this scientific breakthrough, patients are able to get liver, lungs, eyes and heart transplants among other organ transplants. In addition to this, prosthetic parts have enabled many lives to become more efficient. In today’s world, losing a limb through amputation and other such predicaments may not necessarily render one disabled. With prosthetic parts, one is able to carry out activities in their everyday lives. Although life may not be the same for the patient, there is still the opportunity to make their lives more efficient.

  1. Vaccines

Vaccination against deadly diseases was brought about through scientific study and application of theoretic frameworks. In 1798, small pox, which was one of the most deadly diseases on earth received a vaccine which saved countless lives as a result. Even though later on a cure was generated, the vaccine remains an outstanding achievement in such a time where by such scientific advancements had not come of age. Pasteur is also acknowledged for being the first scientist to produce a laboratory-developed vaccine. Every now and then new diseases sprout up in the society and the only way to tackle them is through science. With the help of science, many women are able to give birth to healthy babies each day through vaccinations against various diseases that in the past would lower the mortality rate of children born.

  1. Artificial intelligence

Science has contributed positively in human life through the invention and development of artificial intelligence. With the first actual industrial robot having been built in 1954 by George Devol, strides have been taken over the years to develop on the idea of artificial intelligence. Through artificial intelligence, scientists have been able to mimic the human mind as well as human actions with the application of the limbs. With this, robots have been crafted with the ability to carry out human activities with much more effectiveness and efficiency (Doebelin, 2007). Although a lot of criticism has accompanied the development and advancement of artificial intelligence as it stands to overtake the ability of mankind to perform any activities for economic benefit, this contribution of science remains to be very beneficial to human life.

  1. Genetic engineering

Genetic engineering is another contribution of science to human life. The scientific breakthrough of Boyer and Cohen in1973 where they constructed the first organism through a combination of several DNA samples from different species has led to great success in the food industry. Thirty or so years after the discovery, genetic engineering has seen to high yields in food production through genetic modifications in plant organisms (Vanloqueren, 2009). Genetic engineering has over the years been improved and advanced not only in plants but in animals as well. A recent study showed how scientists in the country have been on the quest to revive dinosaurs in the world through genetically altering the genetic makeup of several animals including cows and elephants. Although the attempts so far have not yet born any success, the audacity of thinking bigger than the surroundings is the reason that science exists.

  1. Nuclear power

Science has contributed to human life through nuclear power. Nuclear power, although seen as disastrous in one way or another, is a safe and pollution-free energy source. Nuclear energy is the second most reliable source of energy after coal and generates about 20 percent of the United States of America’s electricity.

  1. Space exploration

The ability to take men and women to space and back is yet one of the many contributions that science had impacted on human life. The travel to space remains one of the single most brilliant scientific breakthroughs of all time with pioneers of space such as Neil Armstrong and many more astronauts braving through time and space so as to expose to the world the fact that human beings do not exist in a vacuum. Because of such scientific exploration, human beings are able to learn more about the universe.

  1. Microwave energy

Science’s contributions to human life extend in as far as electro-magnetic waves. Electro-magnetic waves are applied in the day to day use of mobile phones, wireless broadband internet as well as satellite television. Moreover, electro-magnetic waves also brought about a new system of preparing food through micro-waves (Doebelin, 2007). Such advancements have helped lighten the load for human beings as the world has become a global village through use of mobile phones and social media platforms through the internet. Furthermore, preparation of food using electro-magnetic waves is one of the fastest ways of getting food ready which saves on time.

  1. Diffraction

Through developments on diffraction originating from the works and observations of Francesco Maria Grimaldi in 1660, optics and fiber optic cables were engineered. As a result, human beings are able to enjoy certain pleasures such as the internet and cable television. This stands as proof of the contributions of science in human life.

In conclusion, science has impacted greatly upon human life. With discoveries and innovative steps in course of understanding nature and the environment, scientists have made mankind better. Scientific contributions to human life such as modern medicine, vaccination, and organ transplants have ensured better medical care for human beings. In addition to this, through genetic engineering, food production has gradually improved especially in the United States of America and other developed countries where genetically modified plants are used to generate high yields annually (Von, 2012). Science has impacted on human interaction through radio waves and electromagnetic waves among others which directly contribute to the production of cellular phones and the internet which has turned the world into a global village.
