Wikipedia:

Boffin is a British slang term for a scientist, engineer, or other person engaged in technical or scientific research and development. A "boffin" was viewed by some in the regular military or government services as odd, quirky or peculiar, though quite bright and essential to helping in the war effort through having and developing the key ideas leading to transformative military capabilities....

So if you are reading this, it might be because a boffin worked for years developing a Blue LED.

Why are blue LEDs important? after all, red LEDs had been around for years.

This video explains why making a blue LED was so difficult, and why this is important. And it also tells the story of the stubborn boffin who found the solution by  doing hands on work, and the two other university scientists whose work contributed to the discovery...

Shuji Nakamura won The Nobel Prize in Physics 2014

shared with Isamu Akasaki and Hiroshi Amano

The Nobel committee explains:

Lighting plays a major role in our quality of life. The development of light-emitting diodes (LEDs) has made more efficient light sources possible. Creating white light that can be used for lighting requires a combination of red, green, and blue light. Blue LEDs proved to be much more difficult to create than red and green diodes. During the 1980s and 1990s Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura successfully used the difficult-to-handle semiconductor gallium nitride to create effecient blue LEDs.

headsup from Kuya.
