    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 price well deserved, and then some.

    This just blew (blue) my mind. I gotta commend you for that explanation of N-type & P-type semiconductors because that was one of the toughest things to grasp in my undergrad electrical engineering courses. I clicked on this video simply because the very first lab assignment we had in my Electronic Design lab course was to design 2 circuits, one basically being a circuit that acts as a television remote that transmits at a certain frequency, and the other circuit being a detector that only operates at that frequency, and once detected, illuminates a BLUE LED. At the time I certainly didn't understand the significance of that color LED at all. I was brand new to any understanding of semiconductors and wouldn't have gone much deeper until the solid-state electronics course I took my senior year (the explanations of semiconductors in this video are still far better than any explanation I received taking that course btw!). This is an incredibly touching story and I'm glad to see he's still doing well and working on the next world-changing thing!
    I'll be wrapping up my Master's degree here in a little over a month. I hope to have the backbone, grit, tenacity, and dedication to do something as incredible as Dr. Nakamura someday!

      Before I finished the video, I was betting that the company was gonna screw him over and he wouldn't get compensation. Lo and behold I just became a prophet. It's a sad state when everyone is expecting a screwjob to happen and it happens. Lawmakers are so head over heels with companies, when they ask for copyright laws, lawmakers would pass bills in a heartbeat. But when an individual citizen is asking for fair policy, nothing ever changes.

      It’s even bigger.. the blue ray laser came from this too. Toshiba freaked out cause they had just wasted years on HDDVD that was obsolete before consumer release. The blue ray could put 50 gig (dual layer) while the Toshiba HDDVDs max was 30 (dual layer). Sony would invest in the blue laser and Nakamura. Toshiba terminated the HDDVD in 2008.

      My whole career I did this. It led to several breakthroughs where the leads would ask how did you do that? Stuff like claiming Java could run as fast as C and proving it out.

      If only Nichia embraced Nakamura's personality, maybe they are one of the biggest companies in Japan.
      Of course, Japanese people don't want change now, they got stuck in the Bubble era

      ​@robotsongs Highly doubt it, people are intellectually lazy. It's easier for folks to focus on the negativity on something, especially if it's new. Instead of learning about what makes it tick and how it could be beneficial. People bandwagon the winning solution, it's a copout and disingenuous.

    Usually, your videos are 15-20 minutes long but this one almost felt like a short documentary. It covered Nakamura's whole career and still focused on all the technical aspects of his work very well. 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.
    You are one of the few people capable of creating this kind of content on such a technical topic. Excellent storytelling without letting the science take a backseat.

      His resilience is pretty normal when it comes to innovative fields. It’s just that a lot of the time, or most of the time when talking unsolvable problems , even resilience doesn’t get the results and you have to decide to stop. Remember, people before him tried for 30 years.

    What a wonderful scientific study. A man fixed on one goal to create a product that changed how people live in such an enormous way. Intelligent, inventive, stubborn, patient and determined to see his vision through by using his innate curiosity and talent to build the product. All of this in furtherance of his PhD and to show people up who had dismissed him in Florida and at his company. A great man.
