What is Quantum Tunneling ?

Quantum Tunneling isn’t a law or a part of the physics we learn in our day to day life but it is part or we can say a theory of quantum Mechanics. First of all, let me tell you what is Quantum Mechanics, Quantum Mechanics means study of matter at atomic or sub-atomic levels. Quantum Mechanics is a theory which is very complex to understand and may seem crazy to a normal person

 Now, let me tell you about Quantum Tunneling……

Quantum Tunneling allows us to go through or pass to a barrier obstructing us. It may be a physical substance, vacuum or a region of high potential energy. For example, According to physics the body needs to have enough energy to pass or travel from one point to another. But Quantum Mechanics says that the body can travel the distance even if the body doesn’t have enough energy to travel (As in classical mechanics).And in the case of Quantum Tunneling, we know that the matter is either wave or a particle and while Quantum Tunneling the wave force starts to act and enables the body to travel

 Now where we can actually see the Quantum Tunneling in action ? The biggest example is our sun, Our Sun produces energy by fusion of hydrogen nuclei that create helium and this process of nuclear fusion produces energy, heat and light in the sun

 But, Most of the Hydrogen nuclei don’t have power to do so .Because, to fuse they need to overcome the power of repulsion of their own positive charge, this is called Coulomb barrier. So, here Using Quantum Tunneling the nuclei overcome the force of repulsion and fuse together

What's Inside A Black Hole?

  Most of us don’t use textbooks or rather don’t even open them except when the exam season arrives, they are just used as a way of “learning” things for the sake of academics. But sometimes during a boring lecture, we come across a word or a concept that suddenly lights up the bulb of our curiosity. This happened to me quite a few times, and the topic I chose today is one of those “concepts that I really don’t understand but they sound cool”. Well not exactly, but yeah that was the case during my 8-9 th grade. Well then, Let’s continue with the topic. Ever learned a mechanism or a concept from science and wondered, “How would it feel to be able to observe this from the inside?” I have always wondered how it feels to actually experience celestial occurrences or phenomena, though it’s not possible for me, or rather any human as of now to go and actually do these things in space. One of the things that made me curious was “Black holes”. What are they exactly? Just an after-deat...

What is Hawking Radiation ?

To know about hawking radiation, first you will need to have a basic idea about “Black Holes”. When a massive star dies, it leaves a dense remnant core. If the mass of that core is  3 times more than the mass of our own sun then the gravitational force overwhelms all the other forces and because of this a Black hole is formed. A black Hole isn’t just an empty space instead it is a space where a lot of things are packed into a very small area. Just think about it, A star that is 10 times bigger than our sun and then it being squeezed into a small area whose diameter maybe as small as a city ! The gravity in the black hole is so Strong that even light and X-rays cannot escape ! Until 1974 when Stephen Hawking put down the theory of Hawking Radiation, it was believed  that the black hole doesn’t emit or radiate any kind of energy. But this changed because of the Hawking radiation theory which was made by combining Quantum mechanics and Einstein’s general theory of relativity. Acc...

What is Mental Health? and Why does it matter?

Image Credit  Well Well, hello there, it’s been a while since I have written/published anything at all. But here I am! Back with a new, interesting, or rather unexpected topic. “Mental Health and Depression”, might not be according to the liking of my usual readers, but I felt mentioning this topic was necessary. Along with that, I had a bit of curiosity about this myself. So, without any further ado let’s begin. First of all, What is mental health? Health as a general term is used to describe the current condition of your body. Similarly, Mental Health is basically the state or the condition of your brain and “heart” i.e., the emotions Mental health includes our psychological as well as social well-being. It determines one’s ability to handle a situation, manage emotions and stress, Decision-making abilities, and so on. A person’s mental health can change over time, depending on many factors. When the demands placed on a person exceed their resources and copi...
