Matter is anything that has mass and takes space. But apart from the ‘normal’ matter, there are different other forms of hypothesized matter. A few examples include Dark Matter, Anti Matter and Negative Matter. You by now know that matter and energy are inter convertible; so there are Dark Energy, Anti Energy and Negative Energy […]

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 infinite range. Let’s see each of them in detail. The Four […]
Fermions and Bosons: Particles Which Make The Universe
There are possibly only two classes of ‘particles’ in the universe – Fermions and Bosons. All elementary particles (Quarks, Leptons, Guage Bosons, Static Bosons etc.) will fall under either of these two. Not only elementary particles, but also composite particles like Baryons (Eg: Protons, Neutrons etc.) will also fall under this basic classification of all […]

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 Bosons (responsible for the forces in nature) and one Higgs Boson. Standard Particle Model […]
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 satisfactorily the behavior of both? Classical […]
Gene Editing – What is CRISPR-Cas9?
Gene editing or genome editing is a way of making specific changes to the DNA of a cell or organism. An enzyme cuts the DNA at a specific sequence, and when this is repaired by the cell a change or ‘edit’ is made to the sequence. Enzymes which cut DNA are known as engineered nucleases […]
Anti-Microbial Resistance (AMR) and the Red Line Campaign
You might have heard about Superbugs which are resistant to all medicines. This is known as Anti-Microbial Resistance (AMR). Studies by WHO has found that in many developing countries including India, the careless use of antibiotics is very prevalent. In this post, we shall discuss the dangers of Anti-Microbial resistance (AMR). We will also cover the Redline […]
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 which is often fatal if untreated. There are currently no licensed Ebola […]
