The Nobel Prize in physics goes to three men who gave us blue light-emitting diodes, used daily in your smartphone screen - The Washington Post
Keywords:
Akasaki of Meijo University, Amano of Nagoya University, Japan, and Nakamura of UC Santa Barbara, produced blue light beams from semiconductors in the 1990's. Nakamura, working for Nichia Chemicals developed his own version of the LED in 1988 following the earlier efforts of Akasaki and Amano, leading to the development of a cheaper easier method of creating LED. The technology is also behind the blue ray disc by using blue lights much shorter wavelength to store 4X more information. Today it is the technology used in smartphone screens.

We took a different way to help millions around the world build educated informed mindsets that affects and shapes their lives. For a future that is open, global and digital, with everyone having access to high quality information. We believe in the renewal of America, renewal of Europe, the renewal of India, the rest of Asia, Latin America and Africa. The renewal of our supply chains, health, education, infrastructure, as we rebuild our countries after the pandemic. Literacy and knowledge we believe cannot thrive and grow in a world of web bots, web crawlers, or AI. This requires human curiosity, human learning, and human imagination. We take as inspiration the saying- “One has to be free, and as broad as sky. One has to have a mind that is crystal clear, only then can truth shine in it.” Every contribution whether big or small is precious- in this crisis and ahead.
