Science plays a vital role in everyone’s life. Science is the process of understanding reality and nature of environment. It involves the observation about the natural world which helps to know about the unknown things to achieve a better understanding about the natural world. The nature of science leads to the development of new technology and inventions about the natural world. The understanding about the science can be useful for the advancement and progress of individual’s everyday lives. Every invention and study that is done in science based on the evidence and reasons which proves its reality in the natural world.
Unless an idea is testable it is little or no use because everything in the natural world needs evidence. The testable ideas come within the scope of science in form of a set of observation that could test if the ideas were true and a set of observations that leads ideas were not true. Everything in the natural world should be tested to make sure that it is safe to use for living beings. These medicine samples are tested on specific plants and animals or if needed then also on human to ensure the verification of the result of medicines. The evidence is from the research that is done on so many diseases to reduce the chronic pain in humans but some of them produce the side effects. The invention of corticosteroids that were acclaimed at high level but later they produce severe and fatal effects like diabetes and ulcers. So, it shows that idea must be testable and check the validity of it to prevent patient from another consequences (O’Brien, W. M.,1969). The atoms had positive and negative charge. It produces the energy when they strike with each other. The opposite charge attracts each other, and the negative charges repel each other. This is clear from the evidence of Rutherford’s gold foil experiment that atom had positive and negative charged electrons distributed throughout the atom. Rutherford thought the idea about doing experiment and then he designed the experiment in which atoms were arranged in that way by placing gold foil and if it was allow alpha particles passes through it, then the idea was true. He noticed that some of the alpha particles passes through the beam and some changed their direction. This clearly gives the evidence about the reason that atoms produced charge because they have positive and negative electrons. (Bandos, 2017)
Good science always begins with observation because when we start thinking about anything then we create a set of observation. Based on these observations we do a hypothesis. Hypothesis is the explanation that is made based as the basis for further investigation from limited evidence. Observation act as a catalyst for scientific observations. Scientists observe the things around them in many ways like by using microscopes and their own sensation of observation. The invention of fire help people to get the cooked food which is germ free and more delicious. The earliest fire logs create more pollution which causes some diseases In agricultural research service chemist Syed H. Imam and his colleagues observed that ecofriendly fire logs can be produced by mixing the lawn clippings with other natural compounds they also use the same formula to produce pellets for the hoper of fire starting sticks for using with firewood at camp fire. These eco logs burn more cleaner and produce less pollution. This way people get more environment friendly fire product which helps them to get their necessary fire by creating less pollution.
Theories help scientists to interpret their observation because theories give the direction to their observation. Scientists plan their observation and investigate them by doing experiment on them. Philosophers assume that the evidential value of an observation depends on the sensitivity of the content which leads to the formation of theory from observation. The evidence comes from the use of thermometer reading to check the temperature and gives the description about the patient’s body temperature. It told about the patient body temperature by challenging with theoretical claims and gives the reading about the patient’s body temperature which indicates the patient’s body temperature that it was against or in favor of body temperature (t). These types of theories are helpful to interpret the observation to give a detailed description about the theories. (Cf. Chang 2005), Azzouni 2004.)
Credit for our advanced way of life must go to science and scientific progress because people get many benefits in the field of health science as many medicines are discovered in order to cure many diseases in which insulin is a good evidence to prove the surety of health science. It is a medicine which is used to cure diabetes. In this disease the proportion of insulin is less in the human body who is suffering from the diabetes. In that case insulin is injected in the human body. It is prepared with the combination of bacterial cells which are also called plasmids and the gene for producing human insulin which is cut out from human DNA. They are further cloned to multiplied into transgenic bacteria and injected into the human body in order to produce insulin in it. The artificial insulin completes the necessary amount of insulin in the body which helps them to cure from the diabetes. This is possible because of the scientific development in the natural worlds (Herold et al., 2015). Genetic engineering helps a lot to improve the life of people and a give a new direction to their life. It improves the production and quality of food which is rich with essential nutrients and protects the crop from harmful bacteria that reduces the productivity and quality of grain. After the discovery of genetic engineering people able to form their desired traits. It is clear from the evidence of golden rice which was invented in 1999 in order to produce vitamin A in it which was lacked in the normal rice. It proved very beneficial for the health of people as it increased their growth and decreased the issue of color blindness in the people. There are many other crops which are also genetically modified as BT cotton, BT rice, BT corn, BT wheat and many more. Harmful bacteria are killed when it come under the contact of these genetically modified crops (Michaels, P. V., 2012).
From the above discussion it is concluded that science needs observation and it also needs the evidence to prove its surety in the public. It is beneficial for people as people get a lot of new techniques to run their life. From the earlier evidence, it is sure that science makes so many changes in human life and make their life easier. Science always keeps on changing with the passage of time by interpreting the other scientists’ ideas and giving rise to new inventions.
