Why It Was Almost Impossible to Make the Blue LED
Veritasium
Veritasium tells the story of how Shuji Nakamura and others made the blue LED, long thought nearly impossible. It covers the materials challenge of gallium nitride and the persistence it took.
HN recommends it as a gripping story of single-minded persistence against the herd, and as the back story behind modern LED lighting.
