Nobel Prizes aren't awarded immediately. They are being acknowledged for something that they did 20 years ago.

All Nobel prizes are awarded for achievements or discoveries made before.
It's not an award for something done recently (or in the previous year). It may for something done 20 years ago.

Edit.
Funny. I wrote 20 years too even though I was writing while Danger were posting already.:)

One exception to that is the Peace Prize, which is usually quite current as is demonstrated by this year's deserving co-winners.

Yes, you are right. I did not think about it but just the physics one.

I think that in the original statutes, it had to be awarded for an innovation of the last year, but this has been changed long ago.

Google suggests the longest wait from original research to prize is 38 years. That went to Ralph Steinman in 2011 for work he did in 1973.

Hm, Peter Higgs wrote his paper in 1964 and got his Nobel prize in 2013.

How could I forget him! So that's 49 years!

Although his was delayed because it took that long to prove he was correct.

If it was, they broke the rule from the beginning, with the first prize in physics which was given to Roentgen in 1901 for the x-rays discovered in 1896.Not 20 years, true. They were faster then. :)

S.Chandrasekhar also got it I think after 50 years for his discovery about chandrashekhar limit.(fate of stars below 1.4 solar masses etc...)

Every physicist does not target prize.Genuine explorers carry on and enjoy their work.

Damned Peace Prize seems to get awarded before there's any evidence of peace at all. (I haven't noticed a lot of it around, lately)

I remember my electronics textbook in the 70s said of LEDs that, theoretically, the only color they should produce is blue, yet up until that time blue was the one color no one had been able to produce.

Clearly, the theory of the day had its shortcomings, too.
