During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the ...

The mathematical physics underpinning electromagnetic fields and wave equations provides a rigorous framework for understanding the behaviour of electric and magnetic phenomena in both classical and ...

An international group of physicists has traced the origin of an electromagnetic interaction to the Dirac equation, a fundamental equation of quantum physics. The interaction couples the spin of the ...

Maxwell described what he could see with magnets and electricity,” Beecham states. 'With modern sensors and the James Webb Space Telescope, we can go further.

Time-domain integral equations (TDIEs) play a central role in the numerical simulation of electromagnetic scattering phenomena. Unlike frequency-domain methods, TDIEs capture the transient behaviour ...

Modern physics and engineering are based on electromagnetism, which controls the interaction of electric currents, magnetic fields, and electromagnetic forces. Every undergraduate student studying ...

Knots can help unravel some knotty (sorry!) situations. The mathematical study of knotted shapes has proved constructive for many branches of physics, from understanding how fluids flow to developing ...
