The pleasure of finding things out

If you focus too much on the outcome, on targets and deadlines and examinations and success or failure, it’s easy to forget why you started doing research in the first place.

It’s easy to end up burned out, stressed and resentful of the very subject that once inspired you.

This can happen to the very best researchers! Richard Feynman, the Nobel-prize-winning physicist widely revered as one of the greatest physicists of the 20th century, described his own experience in his 1985 autobiography, “Surely you’re joking Mr. Feynman”

Then I had another thought: Physics disgusts me a little bit now, but I used to enjoy doing physics. Why did I enjoy it? I used to play with it. I used to do whatever I felt like doing – it didn’t have to do with whether it was important for the development of nuclear physics, but whether it was interesting and amusing for me to play with. When I was in high school, I’d see water running out of a faucet growing narrower, and wonder if I could figure out what determines that curve. I found it was rather easy to do. I didn’t have to do it; it wasn’t important for the future of science; somebody else had already done it. That didn’t make any difference. I’d invent things and play with things for my own entertainment.

So I got this new attitude. Now that I am burned out and I’ll never accomplish anything, I’ve got this nice position at the university teaching classes which I rather enjoy, and just like I read the Arabian Nights for pleasure, I’m going to play with physics, whenever I want to, without worrying about any importance whatsoever.

Within a week I was in the cafeteria and some guy, fooling around, throws a plate in the air. As the plate went up in the air I saw it wobble, and I noticed the red medallion of Cornell on the plate going around. It was pretty obvious to me that the medallion went around faster than the wobbling.

I had nothing to do, so I start to figure out the motion of the rotating plate. I discover that when the angle is very slight, the medallion rotates twice as fast as the wobble rate – two to one. It came out of a complicated equation! Then I thought, “Is there some way I can see in a more fundamental way, by looking at the forces or the dynamics, why it’s two to one?”

I don’t remember how I did it, but I ultimately worked out what the motion of the mass particles is, and how all the accelerations balance to make it come out two to one.

I still remember going to Hans Bethe and saying, “Hey, Hans! I noticed something interesting. Here the plate goes around so, and the reason it’s two to one is …” and I showed him the accelerations.

He says, “Feynman, that’s pretty interesting, but what’s the importance of it? Why are you doing it?”

“Hah!” I say. “There’s no importance whatsoever. I’m just doing it for the fun of it.” His reaction didn’t discourage me; I had made up my mind I was going to enjoy physics and do whatever I liked.

I went on to work out equations of wobbles. Then I thought about how electron orbits start to move in relativity. Then there’s the Dirac Equation in electrodynamics. And then quantum electrodynamics. And before I knew it (it was a very short time) I was “playing” – working, really – with the same old problem that I loved so much, that I had stopped working on when I went to Los Alamos: my thesis-type problems; all those old-fashioned, wonderful things.

It was effortless. It was easy to play with these things. It was like uncorking a bottle: Everything flowed out effortlessly. I almost tried to resist it! There was no importance to what I was doing, but ultimately there was. The diagrams and the whole business that I got the Nobel Prize for came from that piddling around with the wobbling plate.

For the fun of it

The best researchers are driven by curiosity. Feynman described it as “the pleasure of finding things out”, and it seems to be a good way to stay engaged and interested in your work.

But there is another benefit. Just as Feynman’s Nobel ultimately came from playing around with the physics of a spinning plate, many of the greatest discoveries have emerged from simply playing with an idea for the fun of it.

Not everything you do has to be useful. Invest some time in exploring ideas just for the sake of curiosity, for the pleasure of finding things out.

Some of it might turn out to be useful in the long-term, just as some of the things you do for a specific purpose might turn out to be useless. It’s difficult to predict the long-term value of the work you do, but you might as well have some fun while you find out.

    Thanks for posting the Feynman comments. His curiosity along with his wonderful ability to tell delightful stories is something I will always treasure. If he were alive today, he might possibly might express a similar interest and curiosity in quantum computing:-).

    Thank you for sharing :). I think this should be the ultimate purpose, at least for me, while doing the PhD. Have fun! I used to enjoy doing research but now in the writing process (an ideal period for the viva worries to show themselves) I very often feel stressed and disappointed from academia. I will definitely try to focus on the joy of it! I very often think that ‘life is a game’ so let the PhD to be a game as well. Let’s have fun while playing and whether I win or loose, at least it was fun!

    Thanks! So true and so inspiring! Some of my best thinking and most useful work comes out of being in the middle of doing a task and going:
    “Hmm, that looks a bit like something from one of my hobbies/ other interests; I wonder what would happen if I smoosh it together with this bit here from that other place?”
    Or
    “Does this other thing I like/find interesting somehow make what I’m doing better or easier?”
