Free Physics Video and Audio Courses These are the free physics video and audio courses. They are ordered based on their difficulty, starting with easiest first and ending with the most difficult. Also if you love physics, check out my friend's video websites dedicated to three famous physicists: And here are the physics video lectures: Descriptive introduction to physics: No prior physics is required. Classical Mechanics: In addition to the basic concepts of Newtonian Mechanics, Fluid Mechanics, and Kinetic Gas Theory, a variety of interesting topics are covered in this course: Binary Stars, Neutron Stars, Black Holes, Resonance Phenomena, Musical Instruments, Stellar Collapse, Supernovae, Astronomical observations from very high flying balloons (lecture #35), and you will be allowed a peek into the intriguing Quantum World. Introductory Physics Introduction to forces, kinetics, equilibria, fluids, waves, and heat. Electricity and Magnetism: Vibrations and Waves: Symmetry, Structure, and Tensor Properties of Materials
PocketSpacecraft.com | Open source open access personal space exploration Google Book Downloader - Home Maxwell's equations: meaning, derivation and applicability - Classical Physics Quote So if Coulombs law works best for you, then use coulomb's law - there's no need to re-invent the wheel. As far as the original problem goes it is solved, but it uncovered great many things for me, so what is left now is curiosity because this solution implies Coulomb's and Biot-Savart law tell different and more complete story than Maxwell's equations and yet they are supposed to talk about the same E and B fields. There are two kinds of fields, "radial" like gravity and electric fields, and we have "rotational", like vortexes, whirlpools or magnetic fields. The quantity of electric potential of a single electron is discrete and the smallest quantified one, it does not vary or change but only its magnitude is "felt" less as the distance increases in whatever direction. This page here shows you how to get coulomb's law from maxwell's first equation: -- This page says: -"Gauss's law can be derived from Coulomb's law Merged post follows:
Astro Bob | Celestial happenings you can see from your own backyard Skull-A-Day The Second Law and Energy (second law event) 10/05/2007 1:00 PM Broad InstituteSteven Chu, Secretary of EnergyDescription: This Nobel Prize"winning scientist admits to staying up late the night before his talk to bone up on thermodynamics. He puts his research to good use, discussing the history and application of the laws of thermodynamics, which have served as "the scientific foundation of how we harness energy, and the basis of the industrial revolution, the wealth of nations." Taking Watt's 1765 steam engine, Stephen Chu illustrates basic principles of thermodynamics -- that energy is conserved, that you can do work from heat, especially when you maximize the difference in temperature in the system and minimize heat dissipation from friction. Chu offers another form of the laws: You can't win; you can't break even; and you can't leave the game. The game hasn't changed all that much in the past few centuries. Nations now burn coal for electricity, achieving around 40% thermal efficiency. credit license MIT TechTV

(Midori-san the blogging houseplant) Kamakura-based IT company KAYAC Co., Ltd. has developed a sophisticated botanical interface system that lets plants post their thoughts online. The plant "corresponds" via an interface system consisting of surface potential biosensors to read the weak bioelectric current flowing across the surface of the leaves. (Typical blogpost from Midori-san the blogging houseplant) Visitors can give Midori-san a bit of fluorescent light - just click the "Give Light to Midori-San" link, natch. I don't have a specific science-fictional reference for a blogging house plant. Dr. Maybe we shouldn't start plants blogging... Via Pink Tentacle. Scroll down for more stories in the same category.
