How Does Stochastic Electrodynamics Influence Physical Measurements?

AI Thread Summary
Stochastic electrodynamics (SED) integrates quantum concepts into classical electrodynamics, providing a framework for understanding spontaneous electromagnetic radiation. An ideal sensor can convert emissions into measurable signals, with the measurement process potentially linked to SED principles. Fermi's Golden Rule is highlighted as a key tool for calculating transition rates, applicable beyond just photon emission. The discussion emphasizes the relationship between classical and quantum mechanics in measuring physical phenomena. Understanding these concepts is crucial for interpreting data from advanced sensors.

Hi, there.
I am not major in physics so maybe I lack some basic knowledge.
Imagine one have an ideal sensor, which can convert the emission to some kinds of signal (typically, voltage), then what process can describe the measure data? Is it related to http://en.wikipedia.org/wiki/Stochastic_electrodynamics" ?

Spontaneous electromagnetic radiation is a quantum process. Whereas stochastic electrodynamics is the effort to add some quantum concepts into classical electrodynamics without going full quantum, you could also use stochastic electrodynamics to describe spontaneous emission.
 
Thanks for your hint. It seems to be something called http://en.wikipedia.org/wiki/Fermi%27s_golden_rule"

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.
