The popular retelling of how Einstein created Special Relativity to "Resolve the contradictions of Michelson-Morly experiments" is very reductive to the history of the question. The epitome is the quote from the paper:

> From the two postulates, Einstein derived the Lorentz trans- formation ...

If Einstein derived them, who is "Lorentz"?

The groundwork for Special Relativity was the study of electrodynamics and symmetries of Maxwell equations. The Einsteins paper was literally called "On the Electrodynamics of Moving Bodies" and never cites Michelson and Morley.

Einstein seems to be so conveniently dismissive that he knew about the seminal Michelson-Morley experiments but he probably knew about it too well [1].

Einstein is not the first great scientist who are in denial of other important prior contributions, and he also not the last one. Newton also probably knew too well about Al-Haytham (Alhazen), arguably the father of modern science, and his breakthrough experiments but never directly cited Alhazen's works in his seminal books on Optics.

"Abraham Pais, who knew Einstein well and wrote his scientific biography, was certain that Einstein did know about Michelson's experiment before 1905. He points out that Einstein was over seventy and in poor health when he spoke to Shankland; at the first interview he probably did not remember that Michelson's experiment is discussed in Lorentz's 1895 monograph, the famous "Versuch", which Einstein had definitely read before 1905."

  • Was the ethical requirement to discuss and acknowledge predecessors work as developed in Newton's time as in our own? I would naturally expect not because it would seem to me to be the kind of thing that develops over time, but I could be wrong as I am not a historian of science.

    • John Maynard Keynes is famously quoted as stating:

          “[Newton] was not the first of the age of reason. He was the last of the magicians.”

    • It's a not a requirement, it's just a natural to do as a research scientist and a student of knowledge to acknowledge prior contributions if you knew it. The same is true when you are at the time of Aristotle.

    • It reminds me a bit of an anthropology question I've heard brought up a lot that's sort of the dark inverse of xkcd 1053 [0], that many things that "everybody knows" tend to get lost over enough time. You don't need to properly cite experiments or lectures or books that "everybody knows". Especially when the work you do essentially replaces those things in the canon, such connections sometimes get entirely lost. To an anthropologist working in some ancient language the variations of the phrase "as everybody knows" are often a missing or lost citation today. The places where it is so implied that you have the same education or background or textbook as the author to not even warrant an "as everybody knows" is an ever worse thing because you don't even have the marker that you are missing a citation.

  • See also this article, which discusses transcripts from lectures given by Einstein in Kyoto and Chicago in 1922 and 1921 (respectively), and letters from 1899, with earlier accounts of the Michelson-Morley experiment influence:

This isn't offered as a defense of Einstein since I couldn't speculate on what ideas he must have been consciously aware of, but several times in my life I've thought I had a novel idea only to find a very similar idea was in something I read and had just forgotten about. It's a very human phenomenon.

Science rightfully recognizes the mind that doesn't just first describe the idea but provides a robust framework to test it and communicate it.

I agree with you in general. However:

> If Einstein derived them, who is "Lorentz"?

You can (re-) derive a lot of existing stuff.

  • > You can (re-) derive a lot of existing stuff.

    Einstein was aware of Lorentz and the transform. He was aware of Poincaré as well. He knew the state of the art for his time.

I get really tired of Einstein being portrayed as if he’s the greatest scientist who ever lived, when he doesn’t even belong in that conversation. If Einstein never existed, the fields he was in were already moving strongly in the directions of his conclusions. If Maxwell or Newton had never existed, the world today would be quite different.

  • Yeah, once you dig into economics, technology and science of the era it often feels like the big discoveries were inevitable. That doesn't make these people any less great, it's just to say there are many more great thinkers that people are forgetting about.

    But I'd like more explanation as to why Maxwell or Newton are any less replaceable: all 4 of "Maxwell's equations" have other names attached to them (the exception is Ampere-Maxwell law [1] which Maxwell contributed an important term to), and Newton had a number of contemporaries who were making similar discoveries but are often forgotten.

  • Einstein did a lot, he not only published the special and general theories of relativity, he also contributed to quantum physics and was the first to deduce the size of an atom using statistical arguments, essentially proving the existence of atoms.

    • Not at all.

      The size of an atom was computed for the first time 40 years earlier, in 1865, by Johann Josef Loschmidt, who was an Austrian scientist.

      Loschmidt had determined the value of what today is called "Avogadro's number", despite the fact that Avogadro had no idea about how one could find the value at that number. The contribution of Avogadro had been the law that ideal gases have the same number of molecules per volume when the pressure and the temperature are the same, but he did not know how that number might be determined.

      Based on the results of Loschmidt, which were also used by Maxwell in his works on statistical physics, a few years later, in 1874, George Johnstone Stoney computed the value of the elementary electric charge, which he later named "electron".

      Loschmidt was the one who first measured and weighed the atoms, establishing their existence beyond any reasonable doubt. Before him, many believed that the hypothesis of Dalton about the existence of atoms is just a convenient theory for explaining the laws of chemistry, but some other better explanation might be discovered in the future.

      Einstein published an explanation of the Brownian motion, which verified that everything fits in the known theories and it matches the expected values. It did not contain any novel number or law, but it was a useful confirmation of the current theories.

      In my opinion, the greatest achievement of Einstein has been the paper published by him in which he revealed the existence of the stimulated emission of electromagnetic waves by hot bodies, besides their well known absorption and spontaneous emission.

      This paper had tremendous practical applications, leading to the discovery of masers and lasers, without which the modern technology would have never existed.

      While Einstein's theory of gravitation was more intellectually challenging, its practical applications are minor, almost negligible. Moreover, even after more than a century we do not know exactly how adequate it is for describing gravitation.

      What is certain is that Einstein's theory of gravitation cannot be anything else but an approximation, as it is based on averaging the distribution of matter in space, without taking into account the concentration of matter into elementary particles.

      Another contribution of Einstein that is more important than his most frequently cited works is his support for Satyendra Nath Bose, which lead to the recognition of the Bose-Einstein statistics, which together with the Fermi-Dirac statistics plays an essential role in quantum physics.

  • >I get really tired of Einstein being portrayed as if he’s the greatest scientist who ever lived

    fair, there's lots of really awesome scientists, many of which not talked about even 1/100th as often as einstein

    >when he doesn’t even belong in that conversation.

    suddenly, the pendulum has swung way too far in the other direction.

  • Oh boy. I just cannot believe we have reached a point where someone would find it acceptable to have a temper tantrum over Einstein’s fame.

    What a depressingly peculiar time to be alive.

    Reddit is over that way, my friend. You might find the crowd there more amenable to this nonsense.

    • Calling my comment a “temper tantrum” is the exact kind of behavior you’d expect of a Redditor. You may be projecting.

      Einstein’s fame isn’t the problem. It’s the narrative that he is somehow the greatest scientist ever, when it’s just transparently false when you look at his actual contributions and the historical momentum of the fields he contributed to. There’s nothing wrong with his fame, the problem is that it overshadows actual juggernauts, like Maxwell and Newton. Maxwell not being famous at all among the ordinary public is a great tragedy, when he genuinely is in the conversation as having have been the most important physicist to have ever lived.
