Mediocre theoretical physicists make no progress. They spend all their time understanding other people’s progress.

The American doctor, in my opinion, possesses a combination of conservatism and that other quality which has put the United States in the forefront in almost every department of science – that is, an eagerness to know what it is really all about in order that he may not be the one left behind if there is something to it.

It is only through labor and painful effort, by grim energy and resolute courage, that we move on to better things.

There’s always going to be people who don’t understand or accept the united science, and I will just ignore them, as I’m only acting and communicating on the science.

Self-government does not and should not imply the use of political agencies alone. Progress is born of cooperation in the community – not from governmental restraints.

It is too late to be studying Hebrew; it is more important to understand even the slang of today.

Nature gives to every time and season some beauties of its own; and from morning to night, as from the cradle to the grave, it is but a succession of changes so gentle and easy that we can scarcely mark their progress.

The degree of one’s emotions varies inversely with one’s knowledge of the facts.

We know that the nation that goes all-in on innovation today will own the global economy tomorrow. This is an edge America cannot surrender.

It’s very hard for our parents who see us enter a world that they can’t imagine.

We cannot learn from one another until we stop shouting at one another – until we speak quietly enough so that our words can be heard as well as our voices.

A man may imagine things that are false, but he can only understand things that are true, for if the things be false, the apprehension of them is not understanding.

If you deny people their own voice, you’ll have no idea of who they were.

It’s really easy to have a nice philosophy about openness, but moving the world in that direction is a different thing. It requires both understanding where you want to go and being pragmatic about getting there.

I think technology really increased human ability. But technology cannot produce compassion.

We hear only those questions for which we are in a position to find answers.

Really advanced civilization is based on advances in energy.

Science may have found a cure for most evils; but it has found no remedy for the worst of them all – the apathy of human beings.

I think a number of the leaders are, whether you like it or not, in the hip-hop generation. And when they understand enough, they’ll do wonders. I count on them.

In a universe that’s an intelligent system with a divine creative force supporting it, there simply can be no accidents. As tough as it is to acknowledge, you had to go through what you went through in order to get to where you are today, and the evidence is that you did.

If a projectile were deprived of the force of gravity, it would not be deflected toward the earth but would go off in a straight line into the heavens and do so with uniform motion, provided that the resistance of the air were removed.

If everyone is moving forward together, then success takes care of itself.

Nothing recedes like progress.

Developing nations want to become developed nations.

Mystery creates wonder and wonder is the basis of man’s desire to understand.

Each has his past shut in him like the leaves of a book known to him by his heart, and his friends can only read the title.

Thought once awakened does not again slumber; unfolds itself into a System of Thought; grows, in man after man, generation after generation, – till its full stature is reached, and such System of Thought can grow no farther, but must give place to another.

I admire people who dare to take the language, English, and understand it and understand the melody.

Nature knows no pause in progress and development, and attaches her curse on all inaction.

I think if you follow anyone home, whether they live in Houston or London, and you sit at their dinner table and talk to them about their mother who has cancer or their child who is struggling in school, and their fears about watching their lives go by, I think we’re all the same.

Change happens by listening and then starting a dialogue with the people who are doing something you don’t believe is right.

In the material sciences these are and have been, and are most surely likely to continue to be heroic days.

Honest disagreement is often a good sign of progress.

It behooves every man to remember that the work of the critic is of altogether secondary importance, and that, in the end, progress is accomplished by the man who does things.

It seems that I have always been ahead of my time. I had to wait nineteen years before Niagara was harnessed by my system, fifteen years before the basic inventions for wireless which I gave to the world in 1893 were applied universally.

Poor is the pupil who does not surpass his master.

Why not invest in the future of music, instead of building fortresses to preserve its past?

To love someone means to see him as God intended him.

The reason why men do not obey us, is because they see the mud at the bottom of our eye.

I agree with people like Richard Dawkins that mankind felt the need for creation myths. Before we really began to understand disease and the weather and things like that, we sought false explanations for them. Now science has filled in some of the realm – not all – that religion used to fill.

We should understand the source of our authority and something of the keys that control its power.

It is a pleasant thing to reflect upon, and furnishes a complete answer to those who contend for the gradual degeneration of the human species, that every baby born into the world is a finer one than the last.

Unquestionably, there is progress. The average American now pays out twice as much in taxes as he formerly got in wages.

Meditation demands an astonishingly alert mind; it is the understanding of the totality of life in which every form of fragmentation has ceased.

To use the same words is not a sufficient guarantee of understanding; one must use the same words for the same genus of inward experience; ultimately one must have one’s experiences in common.

The best leaders understand the motivations of their team members and know their people – their lives and their families. But a leader must never grow so close to subordinates that one member of the team becomes more important than another, or more important than the mission itself.

If you’re doing a biography, you try to stay as accurate as possible to reality. But you really don’t know what was going on in the person’s mind. You just know what was going on in the minds of people around him.

People talk to people who perceive nothing, who have open eyes and see nothing; they shall talk to them and receive no answer; they shall adore those who have ears and hear nothing; they shall burn lamps for those who do not see.

You can’t say civilization don’t advance… in every war they kill you in a new way.

Love to everybody who is out there progressing and taking things to the next level.

The value of a principle is the number of things it will explain.

Those that know, do. Those that understand, teach.

The beginnings and ends of shadow lie between the light and darkness and may be infinitely diminished and infinitely increased. Shadow is the means by which bodies display their form. The forms of bodies could not be understood in detail but for shadow.
