Introduction
The journey of science began long before it became a formal discipline. It is rooted in natural philosophy— an ancient branch of philosophy (or we can say knowledge) whose main focus is to understand the nature of the physical world around us through observation and inquiry. The era of natural philosophy culminated in the 18th century.
The quest to understand our nature led the visionary thinkers from all corners of the globe to ponder their mind and seek the answer to the questions about our world. Each one of them contributed unique perspectives and discoveries that paved the way for modern science.
The evolution of science can be described to students in this manner.
In ancient Mesopotamia, the Babylonians made significant strides in mathematics and astronomy. They laid the foundational principles, such as a developing a calendar based on movement of moon, that influenced later scholars. In ancient Egypt, the study of medicine also advanced.
In the East, ancient Indian mathematicians like Aryabhata and Brahmagupta introduced concepts of zero and decimal systems, and also developed rules for arithmetic operations. In China, figures like Zhang Heng made early contributions to seismology and astronomy, while the invention of the compass revolutionised navigation.
From the West, people like Aristotle (384–322 BC), Euclid (c. 300 BC), Archimedes (c. 287–212 BC), Hippocrates (c. 460–370 BC), Ptolemy (c. AD 100–170), Claudius Ptolemy (c. 90–168 AD), Pliny the Elder (AD 23–79) laid the groundwork for future scientific inquiry and development, influencing scholars throughout the Middle Ages and beyond.
In the Islamic Golden Age, scholars like Jabir ibn Hayyan (721– 815), Al-Khwarizmi (c. 780–850), Al-Razi (Rhazes) (865–925), Ibn al-Haytham (965–1040), Avicenna (Ibn Sina) (980–1037), Ibn Rushd (Averroes) (1126–1198), Al-Biruni (973–1048), and Ibn Khaldun (1332–1406) helped preserve and expand the knowledge of previous generations and civilisation across the globe.
They worked in various fields including; mathematics, medicine, astronomy, chemistry, philosophy, and literature, registering notable achievements under their name. This is era can be regarded as the transition phase, leading to the classical era in science.
The reason is that, in this era, scholars from diverse backgrounds, including Muslims, Christians and Jews, collaborated and contributed to the flourishing of knowledge, fostering an environment of intellectual tolerance. As a result, many works were translated into Arabic from their original languages, preserving invaluable information.
The Islamic Golden Age (8th–14th century) helped preserve and expand upon the knowledge of earlier civilisations, creating a bridge to the European Renaissance and the Scientific Revolution (roughly the 16th–17th centuries), which is often considered the beginning of the “classical era” in science
During the Renaissance, renowned figures such as Galileo Galilei and Isaac Newton in Europe made groundbreaking contributions that shaped the laws of motion and gravity and thus laid the groundwork for modern physics.
Today, the global scientific community continues this legacy, building on the rich traditions left by those before us. Their contributions have opened doors for diverse thoughts and ideas, deepening our understanding of the universe.
In truth, science is a collective achievement that is shaped by individuals from all races, religions, and backgrounds. No single group in the world can claim ownership of science, as it is not inherited but earned through the efforts and dedication of those who observed nature and sought answers to its mysteries.
Now, let us dive into basic yet essential information that will make you fall in love with science and help you explore this fascinating realm in a fun and easy way.
1. Science | A Vast World of Knowledge
Science is more than just experiments and lab coats. It is the key to unlock the mysteries of the universe! In the broadest sense. It is derived from a Latin word ‘Scientia’, meaning knowledge.
“Science is a branch of knowledge that involves observing, experimenting, and understanding the world around us.”
Science helps explain everything from the stars in the sky to the technology in your pocket. Science is often divided into two categories:
1.1 Natural (Practical) Sciences
Natural science focuses on studying the physical world. Physical world refers to things we can observe, touch, or measure. Physics, chemistry, and biology are examples of natural sciences that help us understand how the universe works.
From how gravity pulls us to the ground to how energy flows through a circuit and lights up our homes, practical sciences explain it all. Natural sciences is divided into two types.
1.1.1 Biological Sciences
Biological sciences is the branch of natural sciences that deals with the study of living organisms, including humans, animals, plants, and microorganisms.
This branch of science includes, Botany (the study of plants), Zoology (the study of animals), Microbiology (the study of microscopic organisms), Genetics (the study of heredity), etc.
1.1.2 Physical Sciences
Physical sciences is the branch of natural sciences that deals with non-living things, systems, and the fundamental laws of the universe.
This branch of science includes, Physics (the study of principles governing energy, motion, and the forces), Chemistry (the study of reactions and transformation of substances), Earth Sciences (the study of Earth and its components, geology, meteorology, and oceanography, Astronomy (the study of celestial objects).
1.2 Social Sciences
Social science focuses on people—how we behave, how societies function, and how we interact with each other. Psychology, sociology, and economics are all part of this group. They help us understand why people act in certain ways and how we can work together to create better communities.
2. Physics | The Heart of Natural Science
It is defined as,
“The branch of physical science that focuses on studying matter, energy, their interaction, and the forces that affect them.“
Have you ever wondered why the Earth orbits the Sun or why our car stops when we hit the brakes, physics is the answer to questions like these. It is the science that explains the rules the universe follows.
From the smallest particles to the largest galaxies, physics helps us understand how everything works.
It is divided into many branches including, Mechanics (the study of motion and rest), Thermodynamics (the study of heat), Optics (the study of light), Acoustics (the study of sound), Electricity and Magnetism (the study of charges and magnet), etc.
3. Mechanics | The Study of State of a Body and Forces
Mechanics is a branch of physics that studies how objects move and the forces that affect them. It includes both the study of objects at rest (statics) and objects in motion (dynamics).
Whether we are throwing a ball, driving a car, watching the planets move through space, or analysing the forces in a bridge that is not moving, mechanics helps explain why and how these motions and forces happen.
Mechanics is often divided into two main parts:
3.1 Statics
Statics, the branch of mechanics, focuses on objects that are not moving. It is all about balance–in other words, two condition of equilibrium (i.e., ΣF = 0 and ΣM = 0).
Ever wondered, how a bridge standing tall without collapsing under the weight of traffic and its own weight—that is statics at work. Engineers use statics to make sure buildings, bridges, and other structures remain stable.
3.2 Dynamics
Dynamics is the branch of mechanics that deals with objects in motion with or without considering the effects of forces and torques involved.
Whenever something is moving—whether it is a car on the road or a planet in orbit—dynamics explains why. There are two key parts to dynamics, kinematics and kinetics.
4. Dynamics | The Study of Motion
Dynamics is all about terms associated with motions, like position, distance, displacement, speed, velocity, and acceleration, as well as, Newton’s laws of motion that explains about forces and inertia.
4.1 Kinematics | Motion without Forces
Kinematics is the branch of dynamics that deals with the motion of an object without considering the effect of forces. It is like describing the path of an object without worrying about what made it move.
It is all about answering the questions like how fast something is going, how far it travels, and how long it takes. Think of it as tracking a race car around a track without asking who stepped on the gas!
4.2 Kinetics | Motion and Forces Combined
Kinetics is the branch of physics that deals with the motion of an object considering the effects of forces. In short, kinetics adds the missing piece to the motion—forces.
Kinetics is about understanding the relationship between the forces acting on an object and the motion that produced as its result. For example, when we push a toy car, kinetics explains how the force of our hand makes it move. It is the perfect blend of motion and the forces that cause it.
5. Why This Matters | The Basic Information About Science
It matters in our daily lives because it forms the foundation of the modern world. From the technology we use and the food we eat to the medicine that keeps us healthy, science is behind almost every aspect of our lives.
