Parth G

Parth G is a physics channel presented by Parth, who aims to make physics fun and approachable. Uploads have been less frequent since early 2025, but the back catalogue is large.

The videos explain one idea at a time, using a whiteboard style and simple maths. Topics include classical mechanics, thermodynamics, quantum mechanics and relativity. He often tackles common misunderstandings, such as what entropy really measures. Most videos run for around ten minutes, so they work well alongside revision or wider reading.

Some highlights include:

An introduction to Lagrangian mechanics compares it with Newton’s laws and shows why it can be easier to use.

An explainer questions the idea that entropy simply means disorder and offers a clearer way to think about it.

A walk through solving the Schrodinger equation for a simple case shows how quantum mechanics is used in practice.

The channel has around 260,000 subscribers.

Mechanics and thermodynamics are core subjects in mechanical, aerospace and chemical engineering degrees. These videos give a head start on ideas that first-year engineering students meet. The quantum videos also connect to electronics and materials, where the behaviour of electrons matters. The short format makes the videos easy to fit around homework, and each one ends with a clear summary of the key idea. They are a helpful bridge between school physics and the kind of reasoning used in university lectures.
