Steinmetz vs Modern Radiation
What Steinmetz Says
Section titled “What Steinmetz Says”Radiation is energy in transit. Heat is produced when radiation is intercepted and absorbed.
What Modern EE Says
Section titled “What Modern EE Says”Electromagnetic radiation carries energy through fields. Thermal radiation is radiation associated with temperature and absorption/emission processes.
Are They Equivalent?
Section titled “Are They Equivalent?”Mostly. Steinmetz’s older language is still conceptually sharp because it refuses to collapse propagation and absorption into a single vague word.
Interpretive Reading
Section titled “Interpretive Reading”Interpretive only: this passage supports field-process thinking, but it should not be overstated as proof of any later ether model.
