The committee added the laureates believed research should be fun.
For instance, Geim managed in 1997 to make a frog levitate in a magnetic field, the jury said, calling it "an ingenious way of illustrating the principles of physics."
On Tuesday, Geim told the committee he was looking at emails and looking at archives when he got the call.
"I slept well, I didn't expect the Nobel Prize this year," he said, adding he was going straight back to work.
"In my opinion there are several categories of Nobel Prize winners, one which after getting the Nobel Prize stop doing anything for the rest of their life. It is a big disservice for the community," he said.
The other category of people, which he said he belonged to, were "people who think people think they won the Nobel Prize by accident so they start working even harder than before."
Last year, Charles Kao, Willard Boyle and George Smith won the physics prize for work on fiber optics and light sensing that helped unleash the Information Technology revolution.
