History of science Science in a broad sense existed before the modern era and in many historical civilizations. In particular, it was the type of knowledge which people can communicate to each other and share.

For example, knowledge about the working of natural things was gathered long before recorded history and led to the development of complex abstract thought. This is shown by the construction of complex calendars, techniques for making poisonous plants edible, public works at national scale, such as those which harnessed the floodplain of the Yangtse with reservoirs, [25] dams, and dikes, and buildings such as the Pyramids.

However, no consistent conscious distinction was made between knowledge of such things, which are true in every community, and other types of communal knowledge, such as mythologies and legal systems. It is thought that early experimentation with heating and mixing of substances over time developed into alchemy.

Nature philosophy In the classical world, there is no real ancient analog of a modern scientist. Instead, well-educated, usually upper-class, and almost universally male individuals performed various investigations into nature whenever they could afford the time.

For this reason, it is claimed these men were the first philosophers in the strict sense, and also the first people to clearly distinguish "nature" and "convention. They were mainly speculators or theoristsparticularly interested in astronomy. The Socratic method as documented by Plato 's dialogues is a dialectic method of hypothesis elimination: This was a reaction to the Sophist emphasis on rhetoric.

The Socratic method searches for general, commonly held truths that shape beliefs and scrutinizes them to determine their consistency with other beliefs.

Socrates was later, in the words of his Apology, accused of corrupting the youth of Athens because he did "not believe in the gods the state believes in, but in other new spiritual beings".

Socrates refuted these claims, [43] but was sentenced to death. Motion and change is described as the actualization of potentials already in things, according to what types of things they are.

In his physics, the Sun goes around the Earth, and many things have it as part of their nature that they are for humans. Each thing has a formal causea final causeand a role in a cosmic order with an unmoved mover.

The Socratics also insisted that philosophy should be used to consider the practical question of the best way to live for a human being a study Aristotle divided into ethics and political philosophy.

Aristotle maintained that man knows a thing scientifically "when he possesses a conviction arrived at in a certain way, and when the first principles on which that conviction rests are known to him with certainty". During late antiquity, in the Byzantine empire many Greek classical texts were preserved.

Many Syriac translations were done by groups such as the Nestorians and Monophysites. Medieval science postulated a ventricle of the brain as the location for our common sense[53]: Byzantine scienceScience in the medieval Islamic worldand European science in the Middle Ages Because of the collapse of the Western Roman Empire due to the Migration Period an intellectual decline took place in the western part of Europe in the s.

In contrast, the Byzantine Empire resisted the attacks from the barbarians, and preserved and improved upon the learning. John Philoponusa Byzantine scholar in the s, was the first scholar ever to question Aristotle's teaching of physics and to note its flaws.

John Philoponus' criticism of Aristotelian principles of physics served as an inspiration to medieval scholars as well as to Galileo Galilei who ten centuries later, during the Scientific Revolutionextensively cited Philoponus in his works while making the case as to why Aristotelian physics was flawed.

Aristotle's four causes prescribed that four "why" questions should be answered in order to explain things scientifically.The protocol described here requires fewer steps, but reproducibly yields DNA from rice grains with A /A and A /A absorbance ratios within the range of – A /A ratio that is higher than is indicative of very pure DNA (Beyenal and Babauta, ).The A /A values for a ‘pure’ nucleic acid commonly reside in the range of – This latest evolution in the LA series advances scientific knowledge for tomorrow’s world through intuitive software, unique accessories, and high performance.

ABSTRACT. Over the past 50 years, there has been increasing amounts of antibiotics used prophylactically and as growth promoters. Today, there is a consumer and governmental outcry to eliminate that practice from poultry and livestock production. Science in a broad sense existed before the modern era and in many historical civilizations.

Modern science is distinct in its approach and successful in its results, so it now defines what science is in the strictest sense of the term. Science in its original sense was a word for a type of knowledge, rather than a specialized word for the . 1 Institute of Chemistry, Federal University of Alfenas, Alfenas, MG, Brazil; 2 Faculty of Pharmaceutical Sciences, Federal University of Alfenas, Alfenas, MG, Brazil Polymorphism in solids is a common phenomenon in drugs, which can lead to compromised quality due to changes in their physicochemical.
