GRAPHENE – A WONDER MATERIAL!

GRAPHENE – A WONDER MATERIAL!

Development in science and technology has truly revolutionized our standard of living. Computers, smartphones, and smartwatches have become a part of our lives and we can’t afford to stay without them in this fast-moving world. But the batteries, which give the potential for our devices to work, drain quickly and its recharging is truly time-consuming, also the batteries are nonbiodegradable and a waste of natural resources.  […]

HOW TRANSISTORS WORK? (BEGINNERS EDITION)

HOW TRANSISTORS WORK? (BEGINNERS EDITION)

Transistors are indeed one of the revolutionary inventions that man has ever made. The function of the transistor is to switch and amplify electrical currents. The number of transistors in dense integrated circuit doubles about every two years. This is Moore’s law. In today’s post, I will introduce you to the semiconductor world and will explain the working of a transistor which has revolutionized our […]

JOURNEY THROUGH QUANTUM MECHANICS

JOURNEY THROUGH QUANTUM MECHANICS

It’s true that there are only a few people who truly understand Quantum phenomena and are able to give satisfactory explanations to others. Quantum Mechanics has always been one of the mindboggling domains in physics. This micro-world never misses an opportunity to surprise us and is always unpredictable. Thanks to the most powerful tool of mathematics because of which we can explore the deepest mysteries of science. In 1808, […]

ABSTRACT NATURE OF TIME

ABSTRACT NATURE OF TIME

Time has been a long run debating topic for many people in the scientific community. The notion of time has changed over the centuries in the field of physics. At around the Newtonian period, time was considered to be flowing at a constant rate and everything in the universe was considered to experience the same time. But during the phase of the early twentieth century, […]

UNDERSTANDING THE FOURTH DIMENSION

UNDERSTANDING THE FOURTH DIMENSION

Hey friends! I assure you that this post would be one of the amazing posts by me. It was very fun to review my old notes and to go through some recent developments on this topic and I assure you to answer all your queries through this post. Before initiating the topic, I would request you to throw away all the methodologies and mindsets for […]

EXPERIMENTAL EVIDENCE OF DARK MATTER AND DARK ENERGY

EXPERIMENTAL EVIDENCE OF DARK MATTER AND DARK ENERGY

Hello and welcome back! I hope you, must have read my last post on ‘gravitational lensing‘ and would be curious to know what contributed to the extra mass? In today’s post, I will explore the 95.1% of the invisible energy density of our universe and eventually answer the question. All the matter which you see on earth, in the cosmos constitutes only 4.9% of the energy density of our […]

GRAVITATIONAL LENSING

GRAVITATIONAL LENSING

WHAT IS GRAVITATIONAL LENSING? A gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer, which is capable of bending the light from the source as the light travels towards the observer.  Gravitational lensing is one of the experimental evidence that objects having mass bends the spacetime. Einstein predicted that if his general theory of relativity […]

WHY MATTER?

WHY MATTER?

After the Big Bang, it’s predicted that our universe had equal and large quantities of matter and anti-matter, but today we observe only matter around us, no anti-matter. So why this imbalance of matter and anti-matter occurred at the beginning of our universe? What exactly caused matter to dominate over anti-matter?  Well, such a question might be answered by baryonic asymmetry or CP-violation. The CP-symmetry […]

BIG BANG FOR BEGINNERS

BIG BANG FOR BEGINNERS

In the twentieth century, Hubble telescope showed us the universe is expanding and the expansion is speeding up which was contrary to the belief that it’s slowing down. After the Big Bang, the universe expanded exponentially and that phase is called inflation. Scientists don’t know what caused the inflation and what stopped it but there are many speculative theories out in the scientific community. If we think from […]

HIGGS MECHANISM AND ITS MISCONCEPTIONS

HIGGS MECHANISM AND ITS MISCONCEPTIONS

In my last blog post, ‘working of the large hadron collider‘, I talked about the Higgs boson (famously known as the ‘God particle’) at a certain instant. Today I will be explaining the Higgs mechanism and will unveil some common misconceptions with Higgs boson. I would also introduce some quantum mechanical equations for better understanding. So throw all your interpretations about the Higgs mechanism and start with […]
