Course Description

This course introduces quantum mechanics in completely non mathematical way. It starts with a brief history of quantum mechanics followed by some of the great successes of quantum mechanics to explain the behavior of atoms and some of most fascinating phenomenon discovered by physicists in the last century such as super fluids, super conductors and condensates of cold atom gases. Then we talk about the fruits of quantum mechanic such as the micro chip, MRI and the laser. It concludes with a discussion of the application of quantum mechanics to understand all the fundamental laws of nature in our universe in of including the theory of everything, the god particle and multiple universes. Some speculations about the nature of human mind are also mentioned.

The course terminology would be mostly non technical. No mathematical equations would be used and the few technical terms that are introduced, would be fully explained in lay man's terms. Anyone with a high school science back ground should be able to follow the course content.

The whole course consists of four video lectures and each lecture is fifteen minutes long. All the content of the course is contained in these lectures. This course does not include any quizes or exercises.

The duration of the course is one hour. Each lecture is a fairly self contained unit. Even though it is recommended that one views the lectures in the order they are presented, each lecture can be viewed separately without much loss of coherence.

This course is recommended for anyone who has ever thought about the fundamental nature of our world, how it came into existence and how the various physical phenomenon are understood from a scientific point of view.

What are the requirements?

  • Some background in physics may be at the high school level, is recommended but not required.

What am I going to get from this course?

  • Course includes 14 lectures and over 1.5 hours of video content
  • Understand some aspects of quantum physics. Quantum physics is absolutely essential to understanding the universe.

Who is the target audience?

  • This course is suitable for anyone who's interested in science, especially physics. You should take this course if you want to understand nature at the most fundamental level for example the God particle. If you have already taken advanced quantum mechanics then probably you don't need to take this course.
  • The entire course is taught without using any mathematics.

Section 1: Introduction to quantum mechanics

This course is a non mathematical introduction to quantum physics. It'll cover various aspects pf quantum physics starting from the history of quantum physics to it's early application to atoms, to the invention of some very important devices such as lasers, MRI and microchips and some of the most fascinating phenomenon discovered by physicists such as superfluids, superconductors and Bose-Einstein condensates. Finally I'll discuss the role of quantum mechanics in understanding the fundamental laws of nature including the god particle, the theory of everything and multiple universes.


In this lecture the history of quantum mechanics is briefly reviewed.


The two corner stones of quantum mechanics - complimentarity and the uncertainty principle are introduced and explained.


Wave mechanics is one of the most successful versions of modern quantum mechanics. It was introduced by Erwin Schrodinger and later Paul Dirac introduced the relativistic version for an electron.

Section 2: Scientific Applications of Quantum Mechanics

Various scientific applications of quantum mechanics are reviewed including atoms and molecules.


Applications of quantum mechanics to metals, semiconductors, insulators and super fluids are reviewed.


Applications of quantum mechanics to super conductors and Bose Einstein condensate are reviewed.

Section 3: Technological Applications of Quantum Mechanics

Various technological applications of quantum mechanics are reviewed. These include microchips.


Two very important technological applications of quantum mechanics are lasers and MRI. These are reviewed here.


Two of the most important recent technological applications of quantum mechanics are quantum computers and quantum encryption.

Section 4: Quantum mechanics and the fundamental laws of nature

Applications of quantum mechanics to fundamental laws of nature are discussed including the Higgs boson.


Elementary particles and their properties; and extra dimensions are discussed in the context of quantum mechanics.


Applications of quantum mechanics to the theory of everything and the idea of multiverse are reviewed.

Instructor Biography

Dr. Sanjay Sood, Professor

I have a PhD in device physics from a US university. I have several years experience in teaching physics in classrooms. I have taught all the introductory classes in physics - both algebra based and calculus based. I also have several years experience in explaining quantum physics in online forums such as quora and research gate where I often answer questions on various aspects of quantum physics.
