      It's good he was able to sue his money back in the end. Sometimes inventors are treated much worse. Sergei Korolev, the key figure in the USSR space program, always comes to my mind when I think about how unfairly and blatantly scientists were treated by the soviet state. He was falsely accused and tortured by the NKVD to make a "confession" and sent to a labour camp, where he has almost died, but then he was "lucky" to be moved to a special prison for scientists and engineers, where conditions were not so dire, and so he was able to continue his brilliant work against all odds, until he was finally discharged by special government decree.

If even a fraction of inventors or researchers in the world had the stamina, determination, resources and insight of this man, the world would be a very different place.
      It is worth noting, that despite the resulting animosity, his original company showed an enormous amount of faith and patience in him. His employment could have been terminated at any time when he was disregarding their orders.

    In the mid 1990s, I was working in a research lab where we were in competition with Nichia in the development of GaN blue LED and lasers, also using our home-grown MOCVD machines. Dr. Nakamura was always 2 (or more!) steps ahead of us. I still vividly remember when we got our hands on a prototype of his deep blue LEDs after a conference. We turned it on in the lab, with lights down, expecting a weak blue emission, as we got from our own devices. It came on so bright and so blue, it illuminated the whole room! It blew our mind, we couldn’t believe it. How had he done that? He was the blue LED magician. Nobel prize well deserved, and then some.

      @@_PatrickO Yes, but to actually get a job, a degree is often a requirement for higher-level careers, and even when it isn't, it sets you apart from other applicants. The reason for why a degree is important isn't because of what you learn in college -as that info can be learned anywhere- but because it provides VERIFICATION and VALIDITY to your knowledge. Typically a job will help a person get the funding they need to begin doing any meaningful research on whatever topic they are looking into.
      You are right in that college doesn't provide any exclusive or different info from what is already available on the internet, but the degree provides certification such that not just your average Joe Schmoe can lie their way into a job and fail to meet its requirements.
      It is very rare when a regular person who has no degree makes any meaningful research papers or inventions. Those are exceptions such as Nikola Tesla. That being said people with the right approach and skill are those exception, at the end of the day true talent is still worth so much more than a piece of paper and years of paying off debt.

      My biggest gripe with modern documentaries is the docu-drama. Either make a straight up documentary or a biopic, none of these in-between stuff. They usually have bad acting, bad dialogue, and they can become repetitive because the actors just repeat what the narrator has already said. It really kills the pacing because you have this 10-minute badly acted scene when the narrator can just explain it in 2 minutes.

      Yes, this is what happens daily. They would keep him in court until he would be in financial ruin.

These companies can keep you in court for as long as they like, just to prevent you from getting some. They must make an example of your, otherwise everyone would be suing companies for giving you a tiny piece of what you give them in the end.

All the electron energy band explanations and animations felt very intuitive with the subtle details like rotations being used to depict electric fields. The explanations neither felt too dumbed-down nor did the video feel overly technical and dry.

    This reminds me of one of my lecturer. He goes around the campus and the place he live by walking while the norm is to at least use a motorcycle. I often see him in the mornings, getting breakfast and smiling to anyone he sees, climbing the stairs with coffee in hand to his office in the third floor, ect. He looks like he enjoys his life and clearly loves what he does, much like Nakamura. I love them so much for that. I wish for the best for them.

      one has to be fair here. its not about 'greed' all the time. thats just a stupid resentment. if you lead a company you are responsible for many things (jobs of all, income of the company and so on) and you cannot put money into everything people come up with - which is also why most startups fail. and people not reflecting that but fall into stereotypes are usually also the ones who blame in other cases a CEO/company for failures which are done if such things go wrong ('how could they with open eyes wasted that much money into a dead horse'? 'everyone knew that this was the wrong direction' and so on). And even Shuji Nakamura himself didnt know that outcome. The point here is that all superficial stereotypes either way are wrong. And the real problems are usually also rather if one acts against the reality ignorant - driven by stupid resentments. I think in even the most cases the success is due to one or a few individuals (a minority, not a majority) - but because of that understanding whats really going on is important. Resentments/prejudices are quite the opposite of that.
