The word science has been derived from a Latin word 'scient' meaning knowledge. It is the study of physical and natural world around us through observations and experiments are done for collecting evidence to prove any topic. The full form of Science is:
"Systematic,Comprehensive Investigation and Exploration of Natural,Causes and Effect"
- Definition of science: Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.
- Importance of science in our daily lives: From dawn till dusk, our lives are surrounded by the fascination of science making it a fundamental part of our daily lifestyle. There's science in everything,
[ ] How heat changes raw food into cooked one
[ ] How washing powders remove dirt from clothes
[ ] Irrigation system of farmers
[ ] Our day to day use of machinery
[ ] Toys with which our children play
- Brief overview of the history of science:
With so much of modernization of science, it's history covers the scientific knowledge gained and experiments done over the course of evolution from ancient times till present in its various fields.
II. Branches of Sciences
- Natural Sciences:It is a branch if science that deals with the physical and natural world which includes phenomenon such as matter,energy,space and time.It comprises of four sub-branches. They are:-
1.Physics- This subject aims to uncover the basic principles that govern natural world around us like how objects interact with each other in space and time,forces affecting them. These principles are expressed through mathematical expressions or by theories.
2.Chemistry- This subject aims to uncover the constituents residing in the matter present in natural world. It describes matter through various aspects like its properties and chemicals and to make new substance from those chemicals.
3. Biology- This subject aims to uncover the living beings and their genes and cells that give them special characteristics. It is basically the study of life. Without this subject it will be difficult to understand the nature of humans,animals and plants which make most of the natural world.
4.Earth Sciences- This subject aims to uncover the physical,chemical and biological aspects of the planet earth which sustains LIFE. It is basically a study of earth's solid structure,water and atmosphere.
- Formal Sciences: It is the branch of science that deals with the Formal systems to generate knowledge in fields of mathematics and computer science. It has three sub-branches. They are:-
1.Mathematics- This subject aims to uncover the methods,theories and theorems that are developed and proved for the needs of empirical Sciences. There are many areas of mathematics such as algebra,decimal system,geometry,theories etc.
2.Logic- This subject aims to uncover the study of reasoning,especially it involves the drawing of inferences.It includes both formal and informal logic.
3. Statistics- This subject aims to uncover the collection,organisation,analysis,interpretation and presentation of the data. It involves estimating a population parameter,describing a sample or evaluating a hypothesis.
- Social Sciences: It is a branch of science that deals with the study of how people interact with each other living in societies.It includes societal norms,public policies and relationships among members living within societies. It has four sub-branches. They are:-
1. Psychology- This subject aims to uncover the thoughts, attitudes and mindset of people towards others. It basically studies the mental states and behavioral Patterns of humans and animals.
2. Sociology- This subject aims to uncover the social life,social change and social causes. It investigates the structure of groups,organizations and societies considering the consequences of human behavior.
3. Anthropology- This subject aims to uncover the evolution origins if distinct species. It basically studies how the human behavior,biology,cultures,societies and linguistics have evolved over a period of generations.
4.Economics- This subject aims to uncover the production,distribution and consumption of goods and services. It's main aim is to find the most effective way of using resources to meet the present and future goals if societies.
- Applied Sciences: It is the branch that studies the use if scientific knowledge and methods to achieve practical goals. Goals such as technological inventions in various fields such as healthcare, agriculture,aquaculture,engineering etc. It has three sub-branches. They are:
1. Engineering- This subject aims to uncover the designs,codes,inventions by scientific principles to make the world a better place. It is the practice of using natural science and mathematics to solve technical problems.
2.Medicine- This subject aims to uncover the diagnosis of diseases and caring for patients. Preventing the disease is the main task in this field of science.
3. Technology-This subject aims to uncover the application of conceptual knowledge to achieve practical goals,especially in a reproducible way.
III. Ancient Civilizations and the Emergence of Science
- Egyptian Science:
Their contribution towards science were very impactful. They were in the following fields:
-Mathematics: They were considered as the pioneers of mathematics.Their geometry was a necessary outgrowth of surveying to preserve the layout and ownership of fertile farmland, which was flooded annually by the Nile River.
-Medicine and surgery: They used plant-based remedies for tumors and inflammation and improved surgeries to greater extent.The Ebers Papyrus describes the use of boswellic acid acetate and salicin, which was extracted from the willow tree.
-Astronomy and Calendars: Their temple astrologers were excellent at determining the movements of stars,sun and moon. With this they used to determine hours,day and night and most importantly their religious festivals.
- Greek Science:
Greek Philosophers like Aristotle developed basis of physics with his natural philosophy, another famous Philosopher was Ptolemy who gave the theory of solar system.
They supposed the universe to comprise of four elements: fire,water,earth and air.
- Roman Science:
They are considered as leaders of science and technology as some of their inventions are still used today.
They excelled in engineering giving the concepts of roads and bridges,developed medical tools for using in battle,they even developed weapons and other tools to use in war.
IV. The Middle Ages and the Islamic Golden Age
- Islamic Contributions to Science
Astronomy was useful for determining the Qibla, the direction in which to pray. Botany had practical application in agriculture, as in the works of Ibn Bassal and Ibn al-'Awwam.
And geography enabled Abu Zayd al-Balkhi to make accurate maps.
Islamic mathematicians such as Al-Khwarizmi, Avicenna and Jamshīd al-Kāshī made advances in algebra, trigonometry, geometry and Arabic numerals.
Islamic doctors described diseases like smallpox and measles.
- European Renaissance:
It was the period of rebirth for the field of Science as many new theories were developed using the classic models of Greek and Roman times. It was marked by advancements in literature, architecture, humanism, and the global economy and thus was considered the period of great discovery.
V. The Scientific Revolution
The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature.
Galileo Galilei - He was known for his telescopic observations of mountains on moon and for the law of free fall which states "In the absence of air resistance, all bodies fall with the same acceleration, independent of their mass."
Isaac Newton- He was known for his law of gravitation and the three famous laws of motion. He explained these workings through mathematics.
Johannes Kepler- He was known for formulating the three laws of planetary motion. He was a German astronomer and mathematician.
VI. Modern Science and Emerging Disciplines
- 19th and 20th Century Advances:
This period saw the emergence of modern technologies in the field of :
Physics: The theory of quantum mechanics which led to development of nuclear weapons.
Chemistry: The new models of atom which led to development of new materials like polyester and nylon.
Biology: The development of generations editing to alter DNA which led to evolutionary processes.
Various new disciplines such as psychology,anthropology were introduced during this period.
- Contemporary Science:
This includes topics such as overexploitation of resources, pollution, desertification, climate change, and biodiversity loss.
The advancements in technology and medicine are getting up to date
The concept of neuroscience is being introduced nowadays.
