A Quote by Richard P. Feynman

You do not know anything until you have practiced. — © Richard P. Feynman
You do not know anything until you have practiced.
The Bible Belt, the religious South, is the section of the country that practiced slavery until the war made them give it up. They practiced segregation. They practiced lynchings. I don't see any great value in that.
The second mode to deal with unsafe cities is to take refuge in vehicles. This is the technique practiced in the big wild-animal reservations of Africa, where tourists are warned to leave their cars under no circumstances until they reach a lodge. It is also the technique practiced in Los Angeles.
I didn't know how interested I was in performing until I did 'Darkplace.' I hadn't done anything really up until that point. I didn't mind the cameras, and I didn't know that I would enjoy it.
I don't know if I practiced more than anybody, but I sure practiced enough. I still wonder if somebody - somewhere - was practicing more than me.
Tennis is a game of angles. You never have time to figure the angles. It's practiced. It's so practiced that it becomes an instinct. You just know where to put the ball. You just feel it. It has been computed into your brain so many times ­ it is there.
Do you know how hard it is to say nothing? When every atom of you strains to do the opposite? I had practiced not saying anything the whole way from the airport, and it was still nearly killing me.
It's a strange thing, you have said it thousands of times I am sure...you will never know what you can do until you try. However the sad truth is, that most people never try anything until they know they can do it.
I've watched all (of Webb's) dunks on tape. I talked to him about what his preparations were going into the dunk contest. He just said he practiced a couple of days before. That's what I did. I practiced for two weeks, I know my routine, and I'm going to go in there, and I'm not going to shy away from it.
I didn't know anything about martial arts. I'm a big fan, but I never practiced martial arts.
Old cranks have practiced all their lives, just as old saints have likewise practiced all their lives. They just practiced different life principles.
You don't know anything about pain until you've seen your own baby drowned in a tub... and you definitely don't know anything about how to wash a baby.
If medicine was practiced in 1965 the way it's practiced today, there's no question that prescriptions would have been included in Medicare.
Ahimsa is the attribute of the soul, and therefore, to be practiced by everybody in all affairs of life. If it cannot be practiced in all departments, it has no practical value.
Justice is that which is practiced by God himself, and to be practiced in its perfection by none but him. Omniscience and omnipotence are requisite for the full exertion of it.
Until you make the effort to get to know someone or something, you don’t know anything.
My cousin cleaned out a shotgun for me and let me carry it around the house, because he said, 'Anybody who knows anything about guns is going to know in a second if someone has held a gun before.' I didn't want to be that person. I wanted to be practiced.
