Molecular biology is one of the most interesting and rapidly expanding branches of modern science. It studies biological molecules such as DNA, RNA, and proteins and how they interact to govern life processes. Molecular biology, which combines biology, chemistry, and genetics, offers profound insights into how living organisms function at the cellular and molecular levels. […]

People have been looking at the night sky and pondering the secrets of the cosmos for generations. Although ground-based telescopes have aided in our exploration of nearby galaxies and stars, Earth’s atmosphere frequently obscures their vision. The space telescopes can help with that. This amazing equipment, which orbits above Earth, produces data and photos so […]

Science is best understood when we witness it in action. Hands-on experiments make learning more engaging, participatory, and memorable. Here’s a collection of simple science experiments that students can conduct at school or at home using minimal materials.   List of science experiments 1. Volcano Eruption with Baking Soda and Vinegar Materials: baking soda, vinegar, […]

Human physiology is the study of how the body works. It explains how cells, tissues, and organs collaborate to keep us alive and well. From breathing to digestion, the beating of the heart to the firing of nerve impulses, physiology explains the complex processes that support life. Levels of Organisation in the Human Body 1. […]

Every living organism depends on thousands of chemical reactions to survive—breaking down food, building proteins, generating energy, and repairing cells. Normally, these responses would be too sluggish to sustain life. Enzymes come into play in this situation—biological catalysts known as enzymes quicken chemical reactions within cells without consuming themselves. 1. What Are Enzymes? Enzymes are […]

Life as we know it is based on the molecules of heredity, DNA & RNA. These nucleic acids store and transmit genetic information, which influences the development, growth, and function of all living creatures. Biology and genetics rely heavily on understanding their structure and differences.   1. What is DNA? DNA (Deoxyribonucleic Acid) is the […]

Cell biology, often known as cytology, is the study of cells’ structure, function, and behaviour. Because cells are the fundamental unit of life, understanding their components and operations is critical in biology, medicine, and biotechnology. 1. Cell Structure Cells can be broadly categorised into two types: Prokaryotic cells – Simple cells without a nucleus (e.g., […]

Modern Physics is the branch of science that explores the fundamental nature of matter, energy, space, and time beyond the boundaries of classical physics. While classical physics—developed by Newton, Maxwell, and others—explains most everyday phenomena, it falls short when describing the microscopic world of atoms or the vast scales of the cosmos. Modern Physics, which […]

The Periodic Table is one of science’s most well-known and useful tools. Often referred to as the “map of elements,” it arranges all known chemical elements in a fashion that emphasises their features, similarities, and interactions. From classroom textbooks to advanced research facilities, the periodic table is the foundation of chemistry and a key to […]

Meteorology is the scientific study of the atmosphere, with emphasis on weather processes and climate trends. It teaches us about the ever-changing sky above us—why it rains, how storms form, what causes heatwaves, and how global climate fluctuations affect our daily lives. Meteorology is critical to human existence and advancement, from forecasting future rainfall to […]

Have you ever noticed how the sound of a passing ambulance siren varies as it gets closer and farther away? The Doppler Effect explains this variation in frequency. The Doppler Effect is commonly associated with sound, but it also applies to light waves, making it one of the most significant instruments in astronomy. What is […]

Light & Optics are among the most fascinating areas of physics. Light allows us to see the world around us, while optics studies how it interacts with objects and surfaces. From the reflection in mirrors to the power of microscopes and telescopes, light & optics explain it all. Reflection of Light Reflection is the bouncing […]

In physics, work, power & energy are key notions that define how forces interact with objects, how energy is stored or transferred, and how activities are completed efficiently. From lifting a book to operating a machine, these rules control practically every aspect of daily life. Understanding them not only broadens your knowledge of physics but […]

Gravitation is one of the most fundamental forces in the universe. It is the unseen pull that keeps us bound to the Earth, controls the motion of planets, and guides the paths of satellites in space. From everyday life to space exploration, gravitation shapes our world in countless ways. Universal Law of Gravitation The great […]

Recently updated on August 20th, 2025 at 03:48 pmReflection of light is not only a simple everyday occurrence but also a cornerstone of optics that explains how images are formed. Without reflection, we would not have mirrors, cameras, periscopes, telescopes, or even the ability to view objects. In this article, we’ll explore what reflection of […]
