Why It Was Almost Impossible to Make the Blue LED

[Don]

If you've never watched the Veritasium channel on YouTube, well, I dare say many here would find it interesting.

For example, why was it almost impossible to make the blue LED? My take away? Had it not been for one stubborn person, we might not be as far along in the LED lighting world as are currently.
