A Quote by Richard P. Feynman

Strange! I don't understand how it is that we can write mathematical expressions and calculate what the thing is going to do without being able to picture it. — © Richard P. Feynman
Strange! I don't understand how it is that we can write mathematical expressions and calculate what the thing is going to do without being able to picture it.
Knowing how to calculate something is not the same as understanding it. Having a computer to calculate the origin of mass for us may be convincing, but is not satisfying. Fortunately we can understand it too.
It was a challenge to be able to create a character without being able to use one's normal set of expressions. All the rubber and makeup attached to your face left you with only a modest range of facial movements.
We can't do without dominating others or being served.... The essential thing, in sum, is being able to get angry without the other person being able to answer back.
The strange thing about being an actor is it's almost a little dangerous to invest in an idea. I think once you invest in the idea of where someone is going, then you're not fully open to being able to play the opposite of that if that's what the character is going to do.
When I - when I was going to school, I knew how to read, write, add and subtract and I - I basically said, 'What else do I need? I'm never going to be able to go to college. I'm not going to be able to afford to go to college. I'm not going to be able to get a scholarship.'
I think most people don't really understand all that it takes to stand on your toes, and to be able to jump and land without any noise, or for a male dancer to be able to lift a girl. All of these things look so effortless, but there's an attention to detail and years of training, as well as being able to transform into a character and being able to meld all of those things together.
In a strange way, you have to have a certain amount of distance from a thing in order to be able to write about it.
To do any important work in physics a very good mathematical ability and aptitude are required. Some work in applications can be done without this, but it will not be very inspired. If you must satisfy your "personal curiosity concerning the mysteries of nature" what will happen if these mysteries turn out to be laws expressed in mathematical terms (as they do turn out to be)? You cannot understand the physical world in any deep or satisfying way without using mathematical reasoning with facility.
Criticized for using formal mathematical manipulations, without understanding how they worked: Should I refuse a good dinner simply because I do not understand the process of digestion?
The process for writing a picture book is completely different from the process of writing a chapter book or novel. For one thing, most of my picture books rhyme. Also, when I write a picture book I'm always thinking about the role the pictures will play in the telling of the story. It can take me several months to write a picture book, but it takes me several years to write a novel.
I'm always trying to calculate the mathematical probability of certain outcomes.
How can we have critical thinking without being able to quote and being able to compare what happened in the past? Television is dreadfully unrecorded and unquotable.
I always thought it was strange when these artists like Kurt Cobain or whoever would get really famous and say, 'I don't understand why this is happening to me.' There is a mathematical formula to why you got famous. It isn't some magical thing that just started happening.
While one man can discover a certain thing by himself, another is never able to understand it, even if taught by means of all possible expressions and metaphors, and during a long period; his mind can in no way grasp it, his capacity is insufficient for it.
I think that we have to be constantly asking ourselves, 'How do we calculate the risk?' And sometimes we don't calculate it correctly; we either overstate it or understate it.
I don't think you ever stop giving. I really don't. I think it's an on-going process. And it's not just about being able to write a check. It's being able to touch somebody's life.
