A selection of images and wallpapers featuring science. Science is defined as “the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment”. There are many different type of scientific specialisations including biology - the study of plants and animals, physics - the study of the physical world, and chemistry - the study of the chemical world. All these areas overlap one another in many ways: for example, animals and plants contain many chemicals and elements such as oxygen and hydrogen, all of which are studies in more details. The human body is studied in great detail in biology but has numerous physical limits that can be better explained and understood using physics.
The world of scientific studies is like a sea of constant change, where any truth or fact discovered is quickly superseded by a higher truth as our pool of knowledge about the world increases. It is only the conclusion to the sum of knowledge so far. Our medical knowledge has advanced remarkably in the last 200 years as techniques and technology has advanced.
