The invention of the blue LED, one of the most difficult and important inventions ever – which allowed the white LED – is some of the craziest Chad shit I have ever heard about anything. This guy is pinnacle determination holy crap.
@SwiftOnSecurity Nakamura may have had a hell of a time perfecting the blue LED (and this video was a great explainer for how he did so), but a far more difficult challenge is apparently any electronics manufacturer using anything other than a blue LED for an indicator lamp since its introduction.
They aren't new and fancy anymore. Can we have amber LEDs back now?
@SwiftOnSecurity Wow! Normally meh on Veritasium videos but this one had the perfect mix of physics + engineering + history/business. Loved it, thanks for sharing.
@SwiftOnSecurity this was a fantastic Veritasium video. I got kind of emotional watching it, and yeah I wish Shuji Nakamura was more well recognized for his contribution to modern society, but I guess it’s videos like this that start that process! I hope he also finds success in the micro-led and fusion fronts. Truly inspiring story, thanks for sharing!
@SwiftOnSecurity I distinctly remember blue LEDs becoming available to hobbyists. Red/Yellow/Green LEDs were about 15p from Maplin (in UK, like Radio Shack), but blue were like £5 each.
@SwiftOnSecurity “Nakamura’s lab mainly consisted of machinery he had scavenged and welded together himself. Phosphorus leaks in his lab created so many explosions that his coworkers had stopped checking in on him.” 👑
@SwiftOnSecurity yeah, it was a major breakthrough and it's a big deal.
the next frontier is solving the green gap problem. right now we don't have efficient semiconductors that have a bandgap with a wavelength in the range between green-yellow and red-amber.
if we can find one, we can stop building white lights that have such a strong blue peak, and make very high efficiency white lights that run the full gamut of the Planckian locus.
@gsuberland@SwiftOnSecurity I picked up the habit of wearing a diffraction grating in my glasses from someone on here years ago and it makes the green gap extremely obvious.
