allowed the sciences to develop further and further as their findings were helpful to research deeper and deeper. An example,[link widoczny dla zalogowanych], applied sciences like mathematics and engineering have allowed the building of more and more powerful computers which, in reverse,[link widoczny dla zalogowanych], allowed the research of mathematical problems in more depth.
Science, from latin “ scientia” (knowledge) and “scire” (to know) is a broad term used to describe “the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.” [New Oxford Dictionary of English]
Science therefore is occupied with the gathering of systematic, i.e. structured, knowledge about the world we live in. We can distinguish two main types of science: a) experimental science (the “why?”) and b) applied science (the “how?”). Both are separate scientific approaches,[link widoczny dla zalogowanych], but also influence each other. Science can equally be divided in the different fields of research, such as natural sciences (for example mathematics, biology, physics) and social sciences (for example history,[link widoczny dla zalogowanych], sociology and psychology). Each of these sciences can exist in several or all of these groups. For example the mathematical sciences can have an experimental or theoretical approach (pure science) and its results can be applied in a practical field such as population statistics (applied science) in the field of sociology (social science).
Science works by observation,[link widoczny dla zalogowanych], experiment,[link widoczny dla zalogowanych], evaluation and prediction. It tries to discover and formulate laws that are able to predict the outcome of similar situations, problems and experiments in future. For example,[link widoczny dla zalogowanych], an experiment regarding the effectiveness of a certain antibiotic towards a certain bacteria has as the ultimate goal to find a reliable treatment for diseases caused by such bacteria,[link widoczny dla zalogowanych], without the need to repeat the experiment before each treatment.
A short history of science
The oldest scientific approach has been the observation and the intent to formulate on the basis of the observed facts a scientific or natural law. Science in this early stage was connected especially with ancient Greek philosophy (Aristotle,[link widoczny dla zalogowanych], Pliny the Elder and the like). In the Mediaeval Ages,[link widoczny dla zalogowanych], centers of science were the monasteries in Europe,[link widoczny dla zalogowanych], and especially the emerging islamic universities in Europe (Spain) and Asia. The real scientific revolution started during the Renaissance and Enlightenment, when the fields of sciences, such as biology and astronomy, were developed and defined. Scientific methods were developed and basic universal measurements,[link widoczny dla zalogowanych], such as the meter,[link widoczny dla zalogowanych], agreed on. Inventions and the scientific approach of
