Although Feynman's most valuable technical contribution to the field of physics may have been in the field of quantum electrodynamics, the Feynman Lectures were destined to become his most widely-read work. The Feynman Lectures are considered to be one of the most sophisticated and comprehensive college-level introductions to physics. [4]

Expensify has developed a reporting expense mobile and web application available in the Apple and Android marketplaces. [5] [15] The app tracks and files expenses such as fuel, travel, and meals; once users photograph receipts, artificial intelligence identifies the merchant, date and amount of the transaction, then automatically categorizes and saves the expense.
It is widely used in colleges as part of the undergraduate physics courses, and has been well known to science and engineering students for decades as "the gold standard" of freshman-level physics texts. In 2002, the American Physical Society named the work the most outstanding introductory physics text of the 20th century.
astrophysics, the physics in the universe, including the properties and interactions of celestial bodies in astronomy; atmospheric physics is the application of physics to the study of the atmosphere; space physics is the study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System
Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change. It is one of the fundamental principles in classical physics, and described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). [1]
Recent work on photosynthesis has provided evidence that quantum correlations play an essential role in this fundamental process of plants and many other organisms. [9] Even so, classical physics can often provide good approximations to results otherwise obtained by quantum physics, typically in circumstances with large numbers of particles or ...
There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the strong nuclear force or weak nuclear force acting on the baryon charge is ...
