Question: When was Plankc's and Einstein's theory formed and how has it impacted physics?
About the article "Electromagnetism", section "Photoelectric effect".

Candidate passages:
When Einstein published his seminal 1905 paper on the particle theory of light, Millikan was convinced that it had to be wrong, because of the vast body of evidence that had already shown that light was a wave.
He undertook a decade-long experimental program to test Einstein's theory, which required building what he described as "a machine shop "in vacuo"" in order to prepare the very clean metal surface of the photo electrode.
His results confirmed Einstein's predictions in every detail, but Millikan was not convinced of Einstein's interpretation, and as late as 1916 he wrote, "Einstein's photoelectric equation... cannot in my judgment be looked upon at present as resting upon any sort of a satisfactory theoretical foundation," even though "it actually represents very accurately the behavior" of the photoelectric effect.
In his 1950 autobiography, however, he simply declared that his work "scarcely permits of any other interpretation than that which Einstein had originally suggested, namely that of the semi-corpuscular or photon theory of light itself".
Since Millikan's work formed some of the basis for modern particle physics, it is ironic that he was rather conservative in his opinions about 20th century developments in physics, as in the case of the photon theory.
Another example is that his textbook, as late as the 1927 version, unambiguously states the existence of the ether, and mentions Einstein's theory of relativity only in a noncommittal note at the end of the caption under Einstein's portrait, stating as the last in a list of accomplishments that he was "author of the special theory of relativity in 1905 and of the general theory of relativity in 1914, both of which have had great success in explaining otherwise unexplained phenomena and in predicting new ones.
"Millikan is also credited with measuring the value of Planck's constant by using photoelectric emission graphs of various metals. 
Although Theodorsen's life work was in aerodynamics, and he published numerous books and papers in that field, he had other interests.
In particular, he wrote a paper, "Relativity and Classical Physics" which sought to show that the results of Einstein's theory of general relativity could be obtained without resorting to curved space-time by a modification of Newton's law of universal gravitation.
The paper presents "a successful transformation of the theory of relativity into classical physics...
The mathematical entities of the Einstein development have been redefined into rational physical quantities and rearranged in an organized classical framework.
Einstein's space-time has been eliminated and replaced by cognitive time."
It was published in the "Proceedings of the DKNVS Theodorsen Colloquium" and on two later occasions.

In differential geometry and theoretical physics, the classification of electromagnetic fields is a pointwise classification of bivectors at each point of a Lorentzian manifold.
It is used in the study of solutions of Maxwell's equations and has applications in Einstein's theory of general relativity. 
Conservapedia has also received criticism for its articles regarding the theory of relativity, particularly on their entry titled "Counterexamples to relativity", an article that lists examples purportedly demonstrating that the theory is incorrect.
Attention was drawn to the article by a "Talking Points Memo" posting, in which they reported on Conservapedia's entry and stated that Andy Schlafly, Conservapedia's founder, "has found one more liberal plot: the theory of relativity".
"New Scientist", a science magazine, criticized Conservapedia's views on relativity and responded to several of Conservapedia's arguments against it.
Against Conservapedia's statements, "New Scientist" stated that one is unlikely to find a single physicist that would claim that the theory of general relativity is the whole answer to how the universe works, and said that the theory of relativity has passed every test that the theory has been put through.
University of Maryland physics professor Robert L. Park has also criticized Conservapedia's entry on the theory of relativity, arguing that its criticism of the principle as "heavily promoted by liberals who like its encouragement of relativism and its tendency to mislead people in how they view the world" confuses a physical theory with a moral value.
In a similar statement, "New Scientist" stated at the end of their article that:In October 2010, "Scientific American" criticized Conservapedia's attitude towards the Theory of Relativity, assigning them a zero score on their 0 to 100 fallacy-versus-fact "Science Index", describing Conservapedia as "the online encyclopedia run by conservative lawyer Andrew Schlafly, implies that Einstein's theory of relativity is part of a liberal plot.
"Another claim is that "Albert Einstein's work had nothing to do with the development of the atomic bomb", and that Einstein was only a minor contributor to the theory of relativity. 
In scientific method, the terms "retrodiction" or "postdiction" are used in several senses.
One use refers to the act of evaluating a scientific theory by predicting known rather than new events.
For example, a theory in physics that claims to extend or replace the standard model but that fails to predict the existence of known particles has not met the test of "postdiction".
Michael Clive Price has written: A retrodiction occurs when already gathered data is accounted for by a later theoretical advance in a more convincing fashion.
The advantage of a retrodiction over a prediction is that the already gathered data is more likely to be free of experimenter bias.
An example of a retrodiction is the perihelion shift of Mercury which Newtonian mechanics plus gravity was unable, totally, to account for whilst Einstein's general relativity made short work of it.
Another use refers to a process by which one attempts to test a theory whose predictions are too long-term to be tested by waiting for a future event to occur.
Instead, one speculates about uncertain events in the more distant past, and applies the theory to consider how it would have predicted a known event in the less distant past.
This is useful in, for example, the fields of archaeology, climatology, evolutionary biology, financial analysis, forensic science, and cosmology.
