The Theoretical Minimum. Physics Homework Help, Physics Help, Physics Tutors. Practical Physics. This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science. Practical activities are not just motivational and fun: they can also sharpen students’ powers of observation, stimulate questions, and help develop new understanding and vocabulary. MathAppendices.
PhysicsCentral: Learn How Your World Works. Physics Documents. The laws list. Science in the News. Top 10 Most Extreme Substances. Chapter 3. Classical physics could not explain the spectra of black bodies.
It predicted that the intensity (power emitted at a given wavelength) of emitted light should increase rapidly with decreasing wavelength without limit (the "ultraviolet catastrophe"). In the figure below, the curve labeled "Rayleigh-Jeans law" shows the classically expected behavior. 10 Strange Things About The Universe. Space The universe can be a very strange place.
While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Physics Formulary: Table of Contents. Last change: December 16, 2009 This document is a LaTeX file of 108 pages which contains a lot of equations in physics.
It is written at advanced undergraduate/postgraduate level. Math, Physics, and Engineering Applets. Oscillations and Waves Acoustics Signal Processing.
Controlled Demolition, Inc. Physics. College Physics. Henry Greenside's Duke Physics Challenges. Duke Physics Challenges The following Physics Challenges are for Duke undergraduates and others to enjoy.
The motivation for these problems comes from Mark Twain's famous quip that "I have never let my schooling interfere with my education. " and similarly I think physics is too much fun to restrict just to classrooms, labs, and homework assignments. If you would like to propose a solution to a Challenge, talk about one of the Challenges, or get a hint, please send me e-mail at email@example.com or drop by my office in the Physics building, Room 097. Please also forward to me any neat problems that you find or invent that would be fun to present as a challenge.
