1 dzień temu · The top row shows a unit pulse as a function of time (f(t)) and its Fourier transform as a function of frequency (f̂(ω)).The bottom row shows a delayed unit pulse as a function of time (g(t)) and its Fourier transform as a function of frequency (ĝ(ω)).Translation (i.e. delay) in the time domain is interpreted as complex phase shifts in the frequency domain.
1 dzień temu · Electromagnetism. Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, electric and magnetic circuits. The equations provide a mathematical model for electric, optical, and radio ...
4 dni temu · An operator is a function over a space of physical states onto another space of states. The simplest example of the utility of operators is the study of symmetry (which makes the concept of a group useful in this context). Because of this, they are useful tools in classical mechanics.
2 dni temu · In April of 2021, the muon’s g -2 was measured to be 0.00233184080, with an uncertainty of ±0.00000000108 attached to it. From new results that were announced in August of 2023, an improvement ...
4 dni temu · So, the simple answer to your question is that, as adverbs, 'once' means the same as 'one time', and 'twice' means the same as 'two times'. They're synonyms that mean either one or two...

3 dni temu · Work and energy. The work W done by a constant force of magnitude F on a point that moves a displacement s in a straight line in the direction of the force is the product. For example, if a force of 10 newtons ( F = 10 N) acts along a point that travels 2 metres ( s = 2 m ), then W = Fs = (10 N) (2 m) = 20 J.
