Resonance is what allows gentle pushes to propel a child ever higher on a swing, and it is what allows whipping winds or marching armies to tear asunder seemingly solid bridges.
Magnetic Resonance Imaging (MRI) is a hugely important medical imaging technique, which works by applying a magnetic field to a person's body and detecting the magnetic resonance of molecules, chiefly hydrogen, in order to determine their distribution.
Resonances are cleanest and easiest to see in simple reactions, and the simplest higher-energy reactions in particle physics come from lepton-antilepton collisions.

 Resonance - Wikipedia, the free encyclopedia
Examples are the acoustic resonances of musical instruments, the tidal resonance of the Bay of Fundy, orbital resonance as exemplified by some moons of the solar system's gas giants, the resonance of the basilar membrane in the biological transduction of auditory input, and resonance in electrical circuits.
The linewidth is inversely proportional to the Q factor, which is a measure of the sharpness of the resonance.
A sharp resonance is a resonance with a sharp peak in the S-matrix (which corresponds to a long lifetime compared to the reciprocal of its mass) while a broad resonance is a resonance with a spread out peak (which corresponds to a short lifetime relative to the reciprocal of its mass).

 Resonance (chemistry) - Wikipedia, the free encyclopedia
Resonance contributors for the same molecule all have the same chemical formula and same sigma framework, but the pi electrons will be distributed differently among the atoms.
Resonance occurs because of the overlap of orbitals.
Resonance should also not be confused with a chemical equilibrium or tautomerism which are equilibria between distinct compounds that have different sigma bonding patterns.

 AllRefer.com - magnetic resonance (Physics) - Encyclopedia
magnetic resonance, in physics and chemistry, phenomenon produced by simultaneously applying a steady magnetic field and electromagnetic radiation (usually radio waves) to a sample of atoms and then adjusting the frequency of the radiation and the strength of the magnetic field to produce absorption of the radiation.
The resonance refers to the enhancement of the absorption that occurs when the correct combination of field and frequency is reached.
In cyclotron resonance the magnetic field is adjusted so that the frequency of revolution of a charged particle around the field lines is exactly equal to the frequency of the radiation.

Examples are the acoustic resonances of musical instruments, the tidal resonance of the Bay of Fundy, orbital resonance as exemplified by some of the Jovian moons, the resonance of the basilar membrane in the biological transduction of auditory input, and resonance in electronic circuits.
Resonance is an important consideration for instrument builders as most acoustic instruments use resonators, such as the strings and body of a violin, the length of tube in a flute, and the shape of a drum membrane.
The resonance of a tube of air is related to the length of the tube and whether it has closed or open ends.

 [No title]   (Site not responding. Last check: )
Nuclear magnetic resonance (NMR) is a physical phenomenon described independently by Felix Bloch and Edward Mills Purcell in 1946 both of whom shared the Nobel Prize in physics in 1952 for their discovery.
Two dimensional nuclear magnetic resonance spectroscopy is a kind of FT-NMR in which there are at least two pulses, and as the experiment is repeated, the time between a pair of pulses is varied.
The first dimension is the frequency of the excitation, and the second dimension is based on the time differential between the pair of pulses (because of the properties of the Fourier transform, this second dimension is eventually expressed as a frequency as well).

 Harmonic Resonance   (Site not responding. Last check: )
B: This chemical harmonic resonance has been identified as the mechanism behind the formation of patterns in animal skins, as well as for the periodicity in the vertibrae of vertibrates, the bilateral symmetry of the body plan, as well as the periodicity of the bones in the limbs and fingers.
Oscillations and temporal resonances are familiar enough in neural systems and are observed at every scale, from long period circadian rhythms, to the medium period rhythmic movements of limbs, all the way to the very rapid rhythmic spiking of the single cell, or the synchronized spiking of groups of cells.
In Waller's technique the resonance is energized by a piece of dry ice pressed against the plate, where the gas generated by sublimation of the ice produces a gap between the ice and the plate that opens and closes periodically as the gas escapes.

 The Physics Classroom
resonance in a musical instrument included the resonance tube (a hollow cylindrical tube) immersed in a cylinder of water and forced into vibration by a tuning fork.
But the resonance tube can be moved up and down within the water, thus decreasing or increasing the length of the air column.
So by moving the resonance tube up and down within the water, the natural frequency of the air in the tube could be matched to the frequency at which the tuning fork vibrates.

 Howstuffworks "How Bridges Work"
Resonance (a vibration in something caused by an external force that is in harmony with the natural vibration of the original thing) is a force which, unchecked, can be fatal to a bridge.
A very famous example of resonance waves destroying a bridge is the Tacoma Narrows bridge, which fell apart in 1940 in a 40-mph (64-kph) wind.
In order to mitigate the resonance effect in a bridge, it is important to build dampeners into the bridge design in order to interrupt the resonant waves.

 Magnetic Resonance Imaging: Encyclopedia of Medicine
Magnetic resonance imaging (MRI) is the newest, and perhaps most versatile, medical imaging technology available.
Magnetic resonance spectroscopy (MRS) is different from MRI because MRS uses a continuous band of radio wave frequencies to excite hydrogen atoms in a variety of chemical compounds other than water.

It is an indication of the importance of labyrinths, and your theme of resonance past and future, that the Council has given permission for me to travel back in time.
The evolution of consciousness consists of cycles of resonance and dissonance, resonance and dissonance.
As soon as there is a period of resonance, consciousness continues to advance, say, in a vertical direction, whereas the social context gets distracted and goes into a more horizontal direction.

 CHEM121 - Resonance & Resonance Structures
Resonance is the use of contributing structures to represent the electronic structure of a molecule.
The degree of energy lowering or molecular stabilization is related to the number of resonance structures and the relative stabilities of the resonance structures.
Resonance structures contribute in proportion to their stability; that is, the more stable the resonance structure, the greater its contribution to the hybrid.

The result of resonance is always a large vibration.
This is resonance - one bob vibrating at a given frequency forcing a second object with the same natural frequency into vibrational motion.
Another classroom demonstration of resonance involved a plastic tube which was raised an lowered in a cylinder of water until the vibrations of the air inside of the tube was tuned to the vibrations of a tuning fork.

 fUSION Anomaly. Resonance
Resonance can also occur in mechanical, structural, and acoustical systems when a system is excited by the continued application of forces at the natural frequency.
Through resonance in a physical system, a small activity or event can gain a great deal of energy; for example, if I belted out a pitch that resonated with the unique acoustic characteristics of this room, the energy of my voice would be amplified by the environment.
The importance of resonance was even sensed and commented on by the volunteers in the PK experiments, in that the most frequently mentioned factor associated with a successful performance was the attainment of a feeling of "resonance" with the machine.
