Not even wrong.
Yes, the internet is full of halfwits posting nonsense.
If ignorance is bliss, then the author of this video has achieved a state of Nirvana.
Physics is a cumulative endeavour. As Newton noted, ""If I have seen further, it is by standing upon the shoulders of giants".
Corpuscular theory of light.
Einstein's contribution was the novel explanation of the
photoelectric effect in terms of quanta - photons. Planck has posited quanta to explain black body radiation, however, he perceived them to be a calculation tool rather than real Einstein's work showed that quanta are real. It was for this work that Einstein was awarded the Nobel prize in physics.
Brownian motion.
Yes, the existence of atoms was an issue of great debate in the late 19th and beginning of the 20th century.
In 1827, the British botanist Robert Brown observed that dust particles inside pollen grains floating in water constantly jiggled about for no apparent reason. In 1905, Albert Einstein theorized that this Brownian motion was caused by the water molecules continuously knocking the grains about, and developed a mathematical model to describe it. This model was validated experimentally in 1908 by French physicist Jean Perrin, thus providing additional validation for particle theory (and by extension atomic theory).
To elaborate, Einstein's contribution was that the
motion of microscopic particles can be predicted directly from the kinetic model of thermal equilibrium, thereby showing that the 2nd law of thermodynamics was statistical in nature,
as
Boltzmann had argued, and thus providing additional evidence for the existence of molecules and atoms. Jean Baptiste Perrin was awarded the Nobel prize in physics for his experiments that tested and confirmed Einstein's prediction.
Special Relativity. E = mc^2
Olinto De Pretto
Both the De Pretto derivation and the speculations of Preston are based on the assumption of the existence of a
luminiferous_aether defining a single universal absolute frame of reference.
Lorentz and Poincaré came far closer than either of these two individuals in their attempts to unify Newtonian dynamics and Maxwellian electrodynamics.
However, their work still assumed the existence of the luminferous aether.
The
Michelson-Morely experiment was designed to detect the aether.
However, the surprising null result, provided strong evidence against the existence of such a hypothesized aether. Further, more accurate and precise, experiments confirmed this null result. This experimental result meant Lorentz's and Poincare's reasonings were non-starters.
The first insight, unique to Einstein, in his theory of Special Relativity was that all inertial frames of reference are equivalent:
physics experiments give the same results in all such frames.
The second insight was the constancy of the speed of light in all such frames for all observers.
These insights yielded the theory of Special Relativity which unified Newtonian mechanics and Maxwellian electrodynamics, into a single simple conceptual framework, while discarding the requirement of what we now know to be a superfluous aether. This was Einstein's revolutionary achievement.
E = mc^2 may be famous, but it is a footnote.
Well, that's it for the video. It never made it to Einstein's
General Theory of Relativity.
Tl;dr: The author of the video is too clueless and, frankly, to dumb to to be able to understand just how clueless he is.
May the gods preserve and defend me from self-righteous altruists; I can defend myself from my enemies and my friends.
