The hertz is defined as one per second for periodic events. The International Committee for Weights and Measures defined the second as "the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom" [3] [4] and then adds: "It follows that the hyperfine splitting in the ground state of the ...
The Hertz equation for the area of contact between two spheres, modified to take into account the surface energy, has the form a 3 = 3 R 4 E ∗ ( F + 6 γ π R + 12 γ π R F + ( 6 γ π R ) 2 ) {\displaystyle a^{3}={\frac {3R}{4E^{*}}}\left(F+6\gamma \pi R+{\sqrt {12\gamma \pi RF+(6\gamma \pi R)^{2}}}\right)}
The Hertz–Knudsen equation describes the non- dissociative adsorption of a gas molecule on a surface by expressing the variation of the number of molecules impacting on the surfaces per unit of time as a function of the pressure of the gas and other parameters which characterise both the gas phase molecule and the surface: [ 1][ 2] where ...

Nyquist–Shannon sampling theorem. The Nyquist–Shannon sampling theorem is an essential principle for digital signal processing linking the frequency range of a signal and the sample rate required to avoid a type of distortion called aliasing. The theorem states that the sample rate must be at least twice the bandwidth of the signal to avoid ...
