@@_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.

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.

Yeah, I was at HP Labs at that time, and we were contemplating spending $10 for a wimpy blue LED to detect yellow ink dots on paper in an inkjet printer, to determine if the inkjet printhead was working. And then came along Shuji Nakamura’s blue LED from Nichia. A mind blowing achievement!

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.

This is such an incredible story that I stumbled upon by sheer accident. Although I wouldn't be able to explain the theory to another, I understood enough to appreciate the hurdles Nakamura had to overcome. Unfortunately he is 1 in a billion. 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. Maybe their are other amazing talents out there, who don't get the opportunity to refine their exceptional abilities.

I did electronic engineering in the late 1990s, when the "blue LED" is finally here craze was just hitting. I literally studied this stuff, as it was happening and even still, this video honestly does a better job of explaining it. As an aside, I also remember the absolute marketing-hype at the time, around gallium being the future and how silicon was "going to be replaced" in a few years by this wonder-stuff (which obviously never panned out).

I'd wondered before about why LED technology seemed to just suddenly be *there*, and this video answered that for me.

Creating blue LEDs was challenging because it required finding a material that could emit blue light efficiently. Traditional LED materials produced red and green light but struggled to produce blue. It wasn't until the 1990s when researchers discovered that certain semiconductor materials, like gallium nitride (GaN), could emit blue light when properly engineered. This breakthrough laid the foundation for the development of blue LEDs, which revolutionized lighting and display technology, but it took years of research and experimentation to achieve.

If management can’t give you enough leeway, then it’s better to push it until you’re successful or fired. 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. Never retreat, attack in a different direction.

Dude is my hero because LED lighting is much more efficient, you can run 8-9 parking lot pole lights or more off a single 20amp circuit with LED. Before you had to use a 30amp circuit for every 3-4 pole light give or take depending on the lights and they generated so much heat that you had to be careful because the heat from the light could melt the electrical wiring. Blue LED is hands down one of the best technological advancements of the 20th century

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.

Very good visualization for laymen. Exceptional actually. But the physics depicted are misleading because electrons never pass through the band gap. They can't or they would be observed in this region, which they never are. This is why and how the band gap is defined. When the molecule is excited an electron will essentially vanish from the lower energy band and another electron will appear in the higher energy band. When the molecule shifts to a lower energy state the opposite happens and the energy is released as a characteristic photon.
