Einstein was right! Albert Einstein predicted the existence of gravitational waves a century ago. Now, scientists confirmed the detection of gravitational waves. This is one of the biggest discoveries of modern science. What are Gravitational Waves? In simple terms, gravitational waves are ripples … [Read more...] about Gravitational Waves: Einstein Was Right!

Ebola Virus Disease – A Challenge to India
Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans. The Ebola virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. The Ebola virus causes an acute, serious illness … [Read more...] about Ebola Virus Disease – A Challenge to India
Genetically Modified Crops and Regulations in India
Genetically modified crops (GM crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques. More than 10% of the world's croplands are planted with GM crops. In most cases, the aim is to introduce a new trait to the plant that does not occur … [Read more...] about Genetically Modified Crops and Regulations in India
Higgs Boson : The God Particle
The standard model of particle physics hypothesized about Higgs Boson in 1964. The discovery of Higgs particle was announced at CERN on 4 July 2012. The discovery has been called monumental because it appears to confirm the existence of the Higgs field, which is pivotal to the Standard Model and … [Read more...] about Higgs Boson : The God Particle
Dark Matter vs Anti Matter vs Negative Matter
Dark Matter, Antimatter, and Negative Matter are concepts from the fields of cosmology and particle physics that have different properties and roles in our understanding of the universe. Read here to understand each term in detail. Matter is anything that has mass and takes space. But apart from … [Read more...] about Dark Matter vs Anti Matter vs Negative Matter
The Four Fundamental Forces of Nature
The Four Fundamental Forces of Nature are Gravitational force, Weak Nuclear force, Electromagnetic force and Strong Nuclear force. The weak and strong forces are effective only over a very short range and dominate only at the level of subatomic particles. Gravity and Electromagnetic force have … [Read more...] about The Four Fundamental Forces of Nature
Fermions and Bosons : Particles Which Make The Universe
Fermions and bosons are two fundamental classes of particles in the field of quantum physics, each with distinct properties and behaviors. These classes of particles play a crucial role in understanding the behavior of matter at the quantum level. Read further to learn more about them. There are … [Read more...] about Fermions and Bosons : Particles Which Make The Universe
Standard Particle Model of Quantum Mechanics: Inside an Atom
Standard Particle Model of Quantum Mechanics is a mathematical model which explains the particle-wave nature of sub-atomic particles. This model proposed two major groups of elementary particles of matter, ie. Quarks and Leptons. The model also proposed elementary force carriers known as Gauge … [Read more...] about Standard Particle Model of Quantum Mechanics: Inside an Atom
Classical Mechanics vs Quantum Mechanics
In this universe there are huge objects like planets and stars. There are also sub-atomic particles like protons and neutrons. You may note that at sub-atomic sizes, the wave nature of particles cannot be neglected and that the particles move at very high speeds. Which theory of Physics explains … [Read more...] about Classical Mechanics vs Quantum Mechanics
The Big Bang Theory
Big Bang Theory is about the origin of the Universe. It suggests that about 1370 crore (13.7 billion) years ago, all matter and energy in the universe was concentrated in an area smaller than an atom. At this instant, matter, energy, space, and time were not existent. Then suddenly with a bang, … [Read more...] about The Big Bang Theory
