There is more to Kirchoff than a law....

AI Thread Summary
Robert Kirchhoff's contributions extend beyond his well-known laws, particularly in the realm of black-body radiation, which laid foundational principles for quantum theory. His work on thermal radiation significantly influenced the development of spectral analysis, a connection that many in electrical engineering may overlook. Helge Kragh highlights that Kirchhoff's definition of black-body radiation in the late 1850s was pivotal to the evolution of quantum theory. The discussion reflects on the historical significance of Kirchhoff's insights and their lasting impact on modern physics. Understanding Kirchhoff's broader contributions can enhance appreciation for his role in the advancement of scientific thought.

Too bad he didn't have PF in 1845. He could have published it as an Insights article. :wink:
 
As an EE I never really connected BBR and Spectral analysis - then to be attributed to him was remarkable'

According to Helge Kragh, "Quantum theory owes its origin to the study of thermal radiation, in particular to the "black-body" radiation that Robert Kirchhoff had first defined in 1859–1860."

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
