INTRODUCTION TO QUANTUM PHYSICS

 By

    Dhruva S. Banavara 


As always, first things first, of course, the basics. So, what is quantum mechanics?

It is the theoretical basis of physics which explains the nature and behavior of matter and energy in very small scales. The compilation of the nature and behavior of matter and energy is referred to as quantum physics or quantum mechanics.

Its uses??

i. The principles Quantum theory is used in the creation of atomic clocks, which are considered to be the most accurate.
ii. It has uses in Electron microscopy, all thanks to Quantum Mechanics. See, Quantum Mechanics advocates that a particle can behave like a wave also. Electrons are particles, but their manifestation as a wave is used in electron microscopy. This causes variations in its resolution; as a result, we can observe finer images. The electron microscope can observe images and stuff which is not possible in a normal microscope.
iii. MRI Scanning (Magnetic Resonance Imaging), This relies on unique Quantum mechanical phenomenon which gives the atomic nuclei of the human body their own magnetic fields, which are then observed by the imaging.
iv. Lasers; they use quantum mechanical phenomenon which allows it to produce inphase light, which deviates very little.

 

Classification

Quantum Mechanics incorporates a few classes of phenomena for which classical physics cannot account for:

-Quantum Entanglement

-Principle of Uncertainty

-Wave-Particle duality.

Quantum Entanglement

This is a quantum mechanical phenomenon in which the quantum states of two or more objects have to be described with reference to each other, even though the individual objects may be spatially separated.

In Physics, the entanglement of particles describes their fundamental properties that can’t happen by chance. This could refer to states such as their momentum, position, or polarization.

 

Principle of Uncertainty

The Uncertainty principle, also known as the Heisenberg Uncertainty principle, articulated by German Physicist Werner Heisenberg, that the position and the velocity of an object both be measured exactly, at the same time, in theory. The very concepts of exact positon and exact velocity together, in fact, have no meaning in nature.

 

Wave-Particle Duality

Wave Particle Duality holds that light and matter exhibit properties of both waves and of articles.

A central concept of quantum mechanics, duality addresses the inadequacy of conventional concepts like “particle” and “wave” to meaningfully describe the behavior of quantum objects.

 

Well, that’s all for the introduction for quantum mechanics. Hope you liked it…☺

Python; Introduction and Installation -PART 1

by    Aneesh R. Prabhu Introducing Python. P ython is an interpreted, high-level and general-purpose programming language. Created by Guido van Rossum and first released in 1991.  Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed. What makes Python special? Often, programmers fall in love with Python because of the increased productivity it provides. Since there is no compilation step, the edit-test-debug cycle is incredibly fast. Debugging Python programs is easy: a bug or bad input will never cause a segmentation fault. Instead, when the interpreter discovers an error, it raises an exception. When the program doesn't catch the exception, the interpreter...

A second home: Mars

by      Chinmaya Srivatsa .K Photo by  Nicolas Lobos  on  Unsplash Introduction to the planet  Ever since the discovery of this red celestial object by Galileo Galilei in the year 1610, this planet has taken our breath away and left us awestruck. Galileo Galilei discovered this planet using a primitive telescope during September of 1610. He became the first man to observe the planet using a telescope. Nowadays, millions observe it during the last week of July of every year when it is closest to our Earth, many countries are planning unmanned space missions to Mars and a few countries are even planning to colonise Mars. If you are interested in the modern history and future of human activities on Mars, this is the right article for you.  Geographic factors  Mars has a number of interesting geographical factors which are similar to Earth’s including Mountains, Valleys, Plains, Volcanoes and Elevated Plains. But, the Martian surface has geograph...

Python; Print Command- PART 3

Image
 by       Aneesh R. Prabhu    The most common instruction given to a computer in any programming language is output some data either to user or console etc. Output Any type of of information we get from the computer is called output and y'll know it. This response you will get from a computer. An instruction is a unit of work for a computer. Values A value is a unit or a multiple units of information, like numbers, strings , character, character of numbers or etc. Print function If we need the computer to show any out, we use print function. Correct way of using Print function  is by typing print(arguments) . We need to pass a argument that computer should display. Arguments When a value is used in a function call, it is called an argument. Arguments are enclosed in parentheses after the function name. i.e <function_name>(<argument>) i.e print("hello world") In the above statement print is the function name and "hello world" is the arg...
