-born in Dresden, Saxony in 1865

-of decisively radical opinions, normal in Saxony but not in rest of Germany

-becomes professor at University of Jena

-has no time for the casual prejudice against Jews of his era, desires Jewish emancipation

-but nevertheless spends most of his time investigating Electrodynamics

-recasts all electrodynamic equations (over twenty) into a mere four equations using the strecke [vector]calculus of Hermann Grassmann in 1889

-no derivation of quaternions ITTL, slowing physics in general down, but use of streckes in thermodynamics growing in 1860s, 1870s

-and this grand success makes him grand success

-this reveals to him, using contemporaneous theory of molecular vortices of the aether, that Ampere's Circuital Law fails when adding displacement current

-adjusts Ampere’s Circuital Law in 1892 by adding displacement current, which is useful in many purposes

-pondering the question of the similarity between dringen waves and light

-as well as links such as light polarization which clearly exist

-leads him to formulate electrodyamic wave equation in 1896

-combining displacement current with other equations

-by speed he determines this wave is light

-this new formulation confuses many, and he has to map this onto [photoelectric effect]by packetizing light

-people aren’t fully convinced, however, till he helps inventor Lombardi develops Photonics, and they both are empowered by this finding

Electrodynamics > ^adc7f8

-when Karl Anton Schrader comes up with electrodynamic wave theory of light (Electrodynamics > ^adc7f8), confronted with fact that the photoelectric effect showing electric energy independent of applied light intensity

-he resolves this by theorizing that light is condensed into paquets, frequency of light multiplied by Schrader constant [Planck constant]in 1898

-that Ampère-Schrader Law seems to disprove existence of classical aether by having constant speed of light, results in growing speculation about what this means

-over next decade Karl Anton Schrader ponders on light being constant speed everywhere and what this means about frames of references

-thought experiment of train at near-speed of light, lamps turned on at same time

-and Galilean transformations yielding nonsense leads him to ponder own theory of invariance

-experiment to measure "aether wind" in 1900, has null result

-suddenly causes controversy, but does prove constant speed of light and Schrader concludes he is looking at right spot

-and Schrader also concludes aether is entirely motionless and constant in all directions

-also writes first form of "Schrader transformations" in 1901, publishes them

-inspired by work on [Doppler]effect, which though based on elastic theory of waves is still valid for electrodynamic notions

-was worked on prior to null result, but in its wake he removes all traces of aether from his work

-although he insists he simply made the aether superfluous under his model

-and thus comes up in 1903 with the two postulates of what we would call special relativity

-here they simply call it invariance theory with focus on speed of light, it is only with new theories in 1950s with rise of rocketry they come up with gravitational invariance and as a result are forced to call this "electrodynamic invariance theory" or "Schrader's invariance theory"

-and upon his death in 1907, secures Schrader's place as the greatest physicist since Newton

-although it takes c. 1920 for it to be fully accepted because aether is irrelevant to it

-dies in 1907 of throat cancer

-with prominence of his discovery related to Photonics, he is well known as the greatest physicist since Newton
