We can understand it clearly with the example of any building that is **made with the help of many materials** like concrete, bricks, etc. so **here the study of the basic point of the building** is the study of individually the concrete and bricks. Similarly in the existence of nature, there is huge matter present in the universe and the **[electrons](https://answers.mindstick.com/qa/49090/who-invented-the-microscope-electron) and protons** are the very least particles present in it. Hence the study of the smallest particle can be said as the [understanding](https://www.mindstick.com/articles/12918/cat-5e-vs-cat-6a-understanding-the-major-differences) of the behavior of the **quantum nature**. \ **Origin of quantum physics** It can be observed from several experiments in the **1800s** and **1900s** of the nature of the atom but these all were not seemed to be fit as per the standard. In the **further experiments**, the study of the **energy** and **matter** was going on than the **[concept of the quanta](https://www.britannica.com/science/quantum)** which is the small number of bundles which are packed with the matter in the **form of energy** and it delivers it in the minimum form and this **can’t be further divided into sub smaller units** and **these bundles of the package are called the ‘quanta’** in Latin words it means ‘**how much’** Some other principles helped in the [development](https://www.mindstick.com/articles/65309/importance-of-ux-design-in-the-development-of-mobile-apps) of quantum physics in the [science world](https://answers.mindstick.com/qa/49751/what-is-the-mean-of-nanotechnology-in-science-world). Some of those are as follows - **Wave-particle duality** - **Superposition** - **[Uncertainty principle](https://plato.stanford.edu/entries/qt-uncertainty/)** - **Entanglement** \ **Examples** of the Quantum physics **Free particle** A free particle is which is not influenced by any other forces. In a single **spatial dimension**, the simplest example of the free particle is the position degree of that particle and the **[Hamiltonian](http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/hamil.html) consists only of its Kinetic energy at that time.** \ **Harmonic Oscillator** In **[classical mechanics](https://answers.mindstick.com/qa/37640/where-can-i-find-the-solution-manual-of-classical-mechanics-by-goldstein)**, a harmonic oscillator is a system in which, when it is **displaced from its equilibrium position** it experiences a **restoring force F** which will be proportional to the displacement X. \ Read more [The hydrocarbon present in Gobar gas is?](https://answers.mindstick.com/qa/51919/the-hydrocarbon-present-in-gobar-gas-is) --- Original Source: https://answers.mindstick.com/qa/49752/what-is-the-quantum-physics-in-science-world Copyright © MindStick Software Pvt.
