MinutePhysics is an educational YouTube channel created by Henry Reich in 2011. The channel's videos use whiteboard animation to explain physics-related topics. Early videos on the channel were approximately one minute long. [2] As of March 2024, the channel has over 5.7 million subscribers.
Produced starting in 1982, the videos make heavy use of historical dramatizations and visual aids to explain physics concepts. The latter were state of the art at the time, incorporating almost eight hours of computer animation created by computer graphics pioneer Jim Blinn along with assistants Sylvie Rueff [3] and Tom Brown at the Jet Propulsion Laboratory.
The PIC was originally conceived to solve problems in fluid dynamics, and developed by Harlow at Los Alamos National Laboratory in 1957. [1] One of the first PIC codes was the Fluid-Implicit Particle (FLIP) program, which was created by Brackbill in 1986 [2] and has been constantly in development ever since. Until the 1990s, the PIC method was ...
A cube magnet levitating over a superconducting material (known as the Meissner effect). Levitation (from Latin levitas, lit. ' lightness ') [1] is the process by which an object is held aloft in a stable position, without mechanical support via any physical contact.
She started making science videos while working as a mobile app developer at General Electric. [11] She started her channel Physics Girl on October 21, 2011. [12] In an interview with Grant Sanderson, she said that some of the earlier videos were later deleted from the channel. [9] Cowern has also participated in various events as a speaker.
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]
Likewise, a theory of everything must work for a wide range of simple examples in such a way that we can be reasonably confident it will work for every situation in physics. Difficulties in creating a theory of everything often begin to appear when combining quantum mechanics with the theory of general relativity , as the equations of quantum ...
Action principles are "integral" approaches rather than the "differential" approach of Newtonian mechanics.[2]: 162 The core ideas are based on energy, paths, an energy function called the Lagrangian along paths, and selection of a path according to the "action", a continuous sum or integral of the Lagrangian along the path.
