How Science Is Done
Science is an organized systematic venture which builds and modifies knowledge in the form of predictions and testable predictions about the natural world. The progress of science has created tremendous intellectual progress, and many fields of scientific study have been developed to tackle some of the most basic questions of nature and to discover the answers for those who seek it. Examples of such areas of inquiry include the study of the atom and molecules, cosmology and space flight, plant growth and development, genetics, immunology, physical anthropology, pharmacology, physiology and many others. In general, science attempts to describe and explain natural phenomena in order to reveal the laws governing the behavior of living things.
One of the most important concepts of science is that of the scientific method, which determines the validity of any experiment and provides evidence for it. This scientific method was first introduced in 1796 by the French Physiologist Fatheraniel Pasteur. He based his ideas on the process of development of all living things. He rejected the then-accepted scientific methods such as natural history, astronomy and geology and stated that there must be a connection between the phenomena of the natural world and those of a laboratory.
The process of science is not just about discovering facts but in providing models and methods for telling those facts. Models in science can be tested and found to be correct almost without fail. Thus, it is imperative for a scientist to come up with a proper hypothesis before starting a scientific experiment. A hypothesis can be an explanation as to why a set of facts has been discovered through an examination of a series of controlled experiments. For example, if scientists find that plants grow faster when they are sprayed with a specific herbicide, a hypothesis may be that the chemicals damage chlorophyll and the production of plants are therefore increased. If, however, they find that the herbicide does not harm the plants at all, the hypothesis will have to be that a unique property of the herbicide makes plants grow faster.
The hypothesis that has been most widely accepted by scientists across the globe is the laws of science itself. This is because science deals with the facts that can be objectively verified and tested through repeated observations and scientific calculations. The scientific method of gathering and evaluating data and then formulating a hypothesis based on these facts is what is known as the scientific method.
One of the most well-known, and still the most dominant, hypotheses in science is the theory of evolution. The theory of evolution states that all forms of life on the planet are related to each other, through common ancestry. The hypothesis also states that these forms of life developed through a process of natural selection over time. The theory of evolution is not based on any type of religious beliefs and has been repeatedly demonstrated through scores of scientific experiments and observations over the years.
An experiment in science can be separated into two different categories: experimental and control. In an experimental group, a set of subjects is used who provide all or virtually all information that is needed to perform a specific experiment. The subjects in an experimental group are kept completely unaware of what they are doing, while the control group is made up of people who know that an experiment is being performed, but remain in an area separate from the laboratory. The control group is made up of people who know nothing about the science behind the experiment, only the information provided to them by the scientists. When the scientists perform the experiment, they are guided by the instructions and procedures written out for them in the report.
