It wasn't. It works fine in certain specialised applications. https://en.wikipedia.org/wiki/Einstein_refrigerator
> He failed to unite the forces of nature
So has everybody else, so far. That doesn't devalue what he did do.
> Aspect's experiment proved his thinking wrong.
https://en.wikipedia.org/wiki/Aspect%27s_experiment It resolved the Einstein&ndash;Podolsky&ndash;Rosen (EPR) paradox which isn't actually proving them wrong - merely answering the interesting question that they were asking/ In physics you get brownie points for asking the right question, adn that was definitely an excellent question.,
> The E=M C^2 something was not his .
He provided a more sensible and comprehensive justification for the equation than anybody else.
> Same for that other thing he put his name on.
Jan hasn't got a clue.
> He was made a hero because he suggested to the then US president to further develop reactions leading to the nuclear bomb.
https://en.wikipedia.org/wiki/Einstein%E2%80%93Szilard_letter In fact it warned Roosevelt that Germany might try to develop a nuclear bomb - as indeed they did. That America responded by developing their own first is scarcely Einstein's fault.
> Jew's hero.
Not only Jews.
> Mass murderer (Hiroshima Nagasaki).
He wasn't asked whether the Americans ought to drop the bomb. Modern war is mass murder. It's hardly fair to blame Einstein for those two incidents when he couldn't have done anything to stop them. The Einstein Slizard letter would have got to Roosevelt even if Einstein hadn't added his signature.
> Endlessly repeating bis babble stops advancement in physics.
Einstein didn't babble, and made substantial contributions to physics. Jan Panteltje lacks the wit to understand any of them. -- Bill Sloman, Sydney

It was a decent refrigerator, but it wasn't competitive, in cost or efficiency of heat source, with the development of mechanical refrigeration (motor driven compressor) using only recently discovered "freon". Einstein's green refrigerator making a comeback https://phys.org/news/2008-09-einstein-green-refrigerator-comeback.html Sounds like the author of article is clueless of the technology. Then I checked the name, and it's a 'Lisa"- which I assume is a female- confirms my suspicion. The same cooling technology has been used in portable applications, like trailers and similar, for 100 years. Most of them use ammonia, and the heat source is a liquid petroleum fueled flame. NASA has developed a few cooling system using the same principle for space based applications, heat source is solar insolation.

Einstein was well known as an uber anti-war pacifist, and mingled with a crowd considered to be political radicals by the U.S. government. He was therefore considered a security risk and denied access to classified material of any kind, before, during, and after the war. But they gave that huckster illiterate Tesla top billing for credibility.

Heinrich Hertz on his experiments with radio waves: "It's of no use whatsoever ... this is just an experiment that proves Maestro Maxwell was right&mdash;we just have these mysterious electromagnetic waves that we cannot see with the naked eye. But they are there." Asked about the applications of his discoveries, Hertz replied: "Nothing, I guess"

Most everything you could say about Maxwell's equations in isolation take up a couple pages, it's Maxwell's equations and _boundary conditions_ that you can write a textbook about.

Heavyside didn't believe EM propagation was possible inside waveguides, he thought you absolutely needed a second conductor. So seems even he sometimes didn't believe what the math was saying.

I often get asked that question about high-energy physics. "What good is the Higgs boson?" My answer is usually something along the lines of "Not much, yet. But would we have had electricity if there hadn't been idle gentlemen playing with glass rods and frog legs? We'll have to wait and see." There are currently some applications of accelerators for cancer treatment. Lately everyone wants his own synchrotron light source for things like materials research on very small scales and time spans. They're still a bit too expensive for extreme resolution lithography, but who knows? Jeroen Belleman

Heaviside&rsquo;s dates are 1850&ndash;1925. The Alexanderson alternator, the first CW transmitter, was invented in 1903. It ran at 200 kHz, iirc, using high speed and many many poles. Even at that, it would have needed a 1-km-wide waveguide, so in H.&rsquo;s era it really wasn&rsquo;t possible.
