Basic history of science :-

The earliest roots of science or the history of the earliest roots can be traced to ancient Egypt and Mesopotamia in around 3500 to 3000 BCE . Their contribution or their role and share to mathematics , astronomy and medicine entered and shaped Greek natural philosopher of classical antiquity , where by formal attempts where made to provide explanation of event in the physical world or the modern world based on natural causes . After the fall(when they come) of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in western Europe during the early centuries ( 400 to 1000 CE ) of the middle age but was preserved in the Muslim world during the Islamic golden age .

The recovery and assimilation of Greek works (Greek language is called “ellinika”)and Islamic inquiries into western Europe from the 10th to 13th century revived natural philosophy , which was later transformed by the scientific revolution that began in the 16th century has new idea and discoveries departed from previews Greek conceptions and traditions. The scientific methods were soon played a greater role in today’s knowledge creation and it was not until from the 19th century that many of the institutional and professional features of science began to take shape .

Basic Scientific Methods :-

The scientific method and Science in general can be frustrating(sad). A theory is almost not proven(proved) and, though a few theories do become scientific laws. One example would be the law of conservation of energy, which is the first law of thermodynamics. Dr Linda Boland (known as professor of biology), a neurobiologist  and chairperson of the Biology department at the University of Richmond, Virginia, told live science that this is her favorite scientific law. ” This is one that guides much of my research on cellular electrical activity and it states that energy cannot be created nor destroyed, only change in form. This law continually reminds me of the many forms of energy, ” Dr. Linda Boland says that…………

Lowers are generally considered to be without exceptions, do some laws have been modified over time after for the testing found discrepancies. This does not mean theories are not meaningful. For a hypothesis (theory, supposition) to become a theory, rigorous testing must occur, typically across multiple disciplines by separate groups of scientists. Saying something is “just a theory” is a layperson’s (who is not a clergyman or a professional person) term that has no relationship to science. To most people as theory is a hunch.
