The physics Nobel for this year has gone to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, for the invention of the blue LED. Check out the official Nobel prize page to see the huge cost savings the invention implies [^]. Very, very, very well deserved!
Congratulations to all the winners.
Their invention has already begun transforming our lives, and, definitely, much more is slated to come. Just to name two: (i) flexible LEDs, (ii) lost-cost designer walls smartly emitting diffuse light (so that the light (in the sense lamp) is not different from the wall, the wall itself is light)… The possibilities are just astounding… For instance, think how it might affect (i) buildings architecture and interior designing, (ii) lighting inside tunnels/underground transportation…. You couldn’t wish for more…
Or, may be, you could! (Hey, this is science and this is life… There is always scope for more!) … If you ask me to single out just one thing, as far as these light- and energy-related matters go, I would choose: cost-effective (i.e. scalable and high energy-density) artificial photo-synthesis. … But then, that is strictly for another day.
As of today, do pause to note here that the realization of the blue LED also took something like three decades! Enormous achievement, that!!
Congratulations to the winners, once again!

A Song I Like:
(Hindi) “pyaar baanTate chalo…”
Singer: Kishore Kumar
Music: Laxmikant Pyarelal
Lyrics: Asad Bhopali
[BTW, if some of you don’t like some part of the lyrics, or of the video, then that can be OK by me, I can understand. Just don’t let it spoil this song itself for you, though. [And, also avoid the cynical temptation to associate this song with the money-distribution that does often go on, at the time of elections.] Instead, just take this song as a song, and appreciate that joyous sense which it carries, the sense of innocence and benevolence which comes so abundantly overflowing from it.]
