- Simple Harmonic (and non-harmonic) Motion § Harvard Natural Sciences Lecture Demonstrations
[S | t | ★★★★] keywords: simple harmonic motion, periodic motion, quantum revival, aliasing What it shows: Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and random motion. One might call this kinetic art and the choreography of the dance of the pendulums is stunning! Aliasing and quantum revival can also be shown. How it works: The period of one complete cycle of the dance is 60 seconds. Setting it up: The pendulum waves are best viewed from above or down the length of the apparatus. Comments: Our apparatus was built from a design published by Richard Berg 1 at the University of Maryland. James Flaten and Kevin Parendo2 have mathematically modeled the collective motions of the pendula with a continuous function. Here at Harvard, Prof Eric Heller has suggested that the demonstration could be used to simulate quantum revival.
Periodicity
Periodicity may refer to: In mathematics[edit] Bott periodicity theorem, describing a periodicity in the homotopy groups of classical groupsFokker periodicity blocks, which mathematically relate musical intervalsPeriodic function, a function whose output contains values that repeat periodicallyQuasiperiodicity, property of a system that displays irregular periodicityFourier series, decomposition of any periodic function or periodic signal into a set of simple oscillating functions In the physical sciences[edit] Periodic trends, relative characteristics of chemical elements observedRedshift periodicity, astronomical term for redshift quantization In accounting[edit] Principle of periodicity, in generally accepted accounting principles See also[edit]

Yelling at a cup of coffee to warm it up? Does that even work? Believe it or not it absolutely does, it just takes a while. Everything that happens, including warming up a cup of coffee or screaming at the top of your lungs, takes energy. The most important thing to remember that the amount of energy is always the same; it can never be spontaneously created or destroyed and thus has to come from somewhere. So what does all this have to do with me hollering at my morning cup of Joe? Sound is just another form of energy, and one that isn’t too different from heat. This dissipated sound energy bouncing around air molecules now takes the same form as heat. Sound carries a relatively low amount of energy while warming up a cup of coffee an appreciable amount takes much more. Calculating this is pretty simple to do once you have the raw data laid out. Q = m · c · (Tf – Ti) There are a lot of implied assumptions when we do this “back of the envelope” calculation. Great! Q = P · t t = Q / P Links:
Scientific Qi Exploration. Sun and Moon Energy
Part 4 of the series Martin Eisen, Ph.D. Sunset at the North pole with the Moon on top 1. The Outer Forces of Heaven are manifested through the Three Treasures: the combined energy field of the sun, moon, and stars. Some of the Five Elements’ correspondences between Heaven’s Treasures and the environment of Earth appear in Table1. Table 1. The body’s biorhythms are influenced by the cyclic energy changes of the sun, moon, and stars. Biorhythms also influence the time and severity of illnesses and the effects of drugs. 2. The Earth’s revolution about the sun causes seasonal energy changes in the organs and meridians of the body. The daily cycle of Heat, Blood, and Qi flow along the body’s twelve Meridians, Organs, and Skin Zones according to two hour time periods appears in Table 2. The fluctuations of Qi in Heaven and Man during the hours and months can be described by the Twelve Pi Hexagrams shown in Table 2. The Yin Yao Cycles The Yang Yao Cycle 1. 2. 3. 4. Table 3. 3.

168. The holy grail of science :
There is a growing number of post quantum physicists who are discovering what Einstein and Schrödinger already assumed; physics may have been on the wrong track all along, misled by the idea that the material world exists of separate solid particles! They are suggesting now that we may live in a wave-based universe. Matter is simply the focal point of a vibration in an energy sea called the aether the Greek scientists and philosophers believed that nature only counted four elements; earth, water, fire and air. The atoms were believed to be the building blocks of these four elements of the universe. Aristotle added the fifth element aether and said that planets and stars were made of this aether. through the articles you will discover a different knowledge about matter that agrees with Plato that the atoms are constructed from the Platonic solids. In the 19th century the aether was well accepted by science now after a hundred years the aether is back in physics. Wave Structure of Matter
Quest for the Truth of Everything
This forum is an open mind forum for both mainstream and amateur scientists, but also ordinary people who want to expand their awareness, wakefulness and understanding of the term truth about our existence. Picasso had a saying that good artists copy and best artists steal ideas. We do not support plagiarism, however we encourage people to connect their thoughts, feel free to talk about their paranormal experiences and to ask as many questions as possible. We have a multidisciplinary approach to revealing the truth about where we all come from and where we are all heading to. That is why we invite Zoologists, painters, brick layers, house wives, truck drivers, Quantum Physicists, Biologists, Mathematicians, poets, artists indeed everybody to participate in this Quest to seek out the Truth of Everything.
