If I'm flying to China, I can sit and think about a problem. Other scientists have to go to the lab. I'm always thinking about maths, even when I'm doing other things. A lot of the time you're going up blind alleys and it's very frustrating, but then you have a sudden rush of ideas. You can live off that for quite some time.
Research is the process of going up alleys to see if they are blind.
As for the search for truth, I know from my own painful searching, with its many blind alleys, how hard it is to take a reliable step, be it ever so small, towards the understanding of that which is truly significant.
Precise adaptation, with each part finely honed to perform a definite function in an optimal way, can only lead to blind alleys, dead ends, and extinction.
With the first 'Toy Story,' we didn't know what the hell we were doing. We'd never made a movie before, so we went down a lot of blind alleys along the way. We went through seven different writers before we finally settled into our groove.
I'm one of the blind alleys off the main road of procreation.
Do not keep saying to yourself, if you can possibly avoid it, 'But how can it be like that?' because you will get 'down the drain,' into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.
You learn more quickly under the guidance of experienced teachers. You waste a lot of time going down blind alleys if you have no one to lead you.
