e. The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century. The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [ 1] It was first proposed as a physical theory in 1931 by Roman Catholic priest and physicist Georges Lemaître when he suggested the universe emerged from a "primeval atom". Various cosmological models of the Big ...
The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. [ 1] Protoscience, early sciences, and natural philosophies such as alchemy and astrology during the Bronze Age, Iron Age, classical antiquity, and the Middle Ages declined ...
Southern blot is a method used for detection and quantification of a specific DNA sequence in DNA samples. This method is used in molecular biology. Briefly, purified DNA from a biological sample (such as blood or tissue) is digested with restriction enzymes, and the resulting DNA fragments are separated by using an electric current to move ...
Colour dispersion angles exaggerated for visualisation. Modern spectroscopy in the Western world started in the 17th century. New designs in optics, specifically prisms, enabled systematic observations of the solar spectrum. Isaac Newton first applied the word spectrum to describe the rainbow of colors that combine to form white light.
The case studies below show how prevalent Locard's Exchange Principle is in each and every crime. [citation needed] The examples using Locard's Principle show not only how the transfer of trace evidence can tell the tale of what happened, [citation needed] [dubious – discuss] but also how much care is required when collecting and evaluating trace evidence.
New experiments raise important questions on what it means to die.
