Resonance Cascade 

A fictional phenomenom where waves of energy combine in a continual loop (cascading). In essence, the energy multiplies out of control. See Resonance Reversal.
I never thought I'd see a Resonance Cascade, let alone create one!

Nuclear magnetic resonance spectroscopy (NMR) 

Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique to observe local magnetic fields around atomic nuclei. The sample is placed in a magnetic field and the NMR signal is produced by excitation of the nuclei sample with radio waves into nuclear magnetic resonance, which is detected with sensitive radio receivers. The intramolecular magnetic field around an atom in a molecule changes the resonance frequency, thus giving access to details of the electronic structure of a molecule and its individual functional groups. As the fields are unique or highly characteristic to individual compounds, in modern organic chemistry practice, NMR spectroscopy is the definitive method to identify monomolecular organic compounds.
Person 1: Do you think our laboratory needs an NMR-spectrometer?

Person 2: I've heard they're unbelievably expensive, but Nuclear magnetic resonance spectroscopy (NMR) is an essential analytical procedure for sure .

cyclotron resonance 

plasma in a magnetic field is heated through the resonance effect when the vibration frequency of an oscillating electromagnetic field matches the gyro-frequency of the charged particles in the plasma. This effect is known as Ion Cyclotron Resonance Heating, and enables the generation of superheated plasma over 100 million degrees celcius of temperature.
this definition is pretty much ruining the title "urban" dictionary. but every dictionary should have something like cyclotron resonance.

Word of the Day on November 3, 2026
Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
Along with Nixon’s other ratfuckers, Roger Stone caused fights at otherwise peaceful Democratic Party protests to generate a false narrative that the Democrats were violent and dangerous.
