Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine.

Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more.

Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine.

Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.

I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success... such emotions make a man forget food, sleep, friends, love, everything.

The spread of civilisation may be likened to a fire; first, a feeble spark, next a flickering flame, then a mighty blaze, ever increasing in speed and power.

The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane.

All knowledge or form conception is evoked through the medium of the eye, either in response to disturbances directly received on the retina or to their fainter secondary effects and reverberations. Other sense organs can only call forth feelings which have no reality of existence and of which no conception can be formed.

Archimedes was my ideal. I admired the works of artists, but to my mind, they were only shadows and semblances. The inventor, I thought, gives to the world creations which are palpable, which live and work.

Every living being is an engine geared to the wheelwork of the universe. Though seemingly affected only by its immediate surrounding, the sphere of external influence extends to infinite distance.

From my childhood I had been intended for the clergy. This prospect hung like a dark cloud on my mind.

I do not think you can name many great inventions that have been made by married men.

I myself eschew all stimulants. I also practically abstain from meat.

If we want to reduce poverty and misery, if we want to give to every deserving individual what is needed for a safe existence of an intelligent being, we want to provide more machinery, more power. Power is our mainstay, the primary source of our many-sided energies.

In the twenty-first century, the robot will take the place which slave labor occupied in ancient civilization.

It is paradoxical, yet true, to say, that the more we know, the more ignorant we become in the absolute sense, for it is only through enlightenment that we become conscious of our limitations. Precisely one of the most gratifying results of intellectual evolution is the continuous opening up of new and greater prospects.

Modern science says: 'The sun is the past, the earth is the present, the moon is the future.' From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom.

Of the various branches of electrical investigation, perhaps the most interesting and immediately the most promising is that dealing with alternating currents.

The earth is bountiful, and where her bounty fails, nitrogen drawn from the air will refertilize her womb. I developed a process for this purpose in 1900. It was perfected fourteen years later under the stress of war by German chemists.

The feeling is constantly growing on me that I had been the first to hear the greeting of one planet to another.

The history of science shows that theories are perishable. With every new truth that is revealed we get a better understanding of Nature and our conceptions and views are modified.

The trend of opinion among eugenists is that we must make marriage more difficult. Certainly no one who is not a desirable parent should be permitted to produce progeny.

The year 2100 will see eugenics universally established. In past ages, the law governing the survival of the fittest roughly weeded out the less desirable strains. Then man's new sense of pity began to interfere with the ruthless workings of nature. As a result, we continue to keep alive and to breed the unfit.

There is no conflict between the ideal of religion and the ideal of science, but science is opposed to theological dogmas because science is founded on fact. To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine.

There is no memory or retentive faculty based on lasting impression. What we designate as memory is but increased responsiveness to repeated stimuli.

We have soon to have everywhere smoke annihilators, dust absorbers, ozonizers, sterilizers of water, air, food and clothing, and accident preventers on streets, elevated roads and in subways. It will become next to impossible to contract disease germs or get hurt in the city, and country folk will got to town to rest and get well.

When a coil is operated with currents of very high frequency, beautiful brush effects may be produced, even if the coil be of comparatively small dimensions. The experimenter may vary them in many ways, and, if it were nothing else, they afford a pleasing sight.

With ideas it is like with dizzy heights you climb: At first they cause you discomfort and you are anxious to get down, distrustful of your own powers; but soon the remoteness of the turmoil of life and the inspiring influence of the altitude calm your blood; your step gets firm and sure and you begin to look - for dizzier heights.

Anti-social behavior is a trait of intelligence in a world full of conformists.

Every living being is an engine geared to the wheelwork of the universe. Though seemingly affected only by its immediate surrounding the sphere of external influence extends to infinite distance.

Let the future tell the truth and evaluate each one according to his work and accomplishments. The present is theirs the future for which I have really worked is mine.

The day science begins to study non-physical phenomena, it will make more progress in one decade than in all the previous centuries of its existence.

The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain.

The mind is sharper and keener in seclusion and uninterrupted solitude. Originality thrives in seclusion free of outside influences beating upon us to cripple the creative mind. Be alone "that is the secret of invention: be alone, that is when ideas are born.

No matter what accomplishments you make, somebody helped you.

No matter what accomplishments you make, somebody helps you.

I had no accomplishments except surviving. But that isn't enough in the community where I came from, because everybody was doing it. So I wasn't prepared for America, where everybody is glowing with good teeth and good clothes and food.

I thought I would reflect here on a theme most scientists enjoy recalling: the part luck played in their accomplishments.

The sports page records people's accomplishments, the front page usually records nothing, but man's failures.

However, I hope I am also judged on my accomplishments as an actor and not just on my pretty face!

Do not let your grand ambitions stand in the way of small but meaningful accomplishments.

Her death contributed to my later interest in studying biochemistry, an interest that has not been fulfilled in the sense that my accomplishments remain more at the basic than the applied level.

I think a lot of Jim Thorpe, the Olympian, and his accomplishments.

We know these men are professionals whose services are up for bid and whose bags are packed, and yet we call them our own and take personal, even civic pride in their accomplishments.

Getting a degree, being on Sesame Street... those were like real accomplishments to me.

A man's accomplishments in life are the cumulative effect of his attention to detail.

The intelligent man is one who has successfully fulfilled many accomplishments, and is yet willing to learn more.

Man can acquire accomplishments or he can become an animal, whichever he wants. God makes the animals, man makes himself.

I've been a very lucky guy. I played on championship teams. I played for Canada. I've won some awards and I'm very proud of those accomplishments. But I don't think there's anything greater than to come home and to be recognized at home. This is the pinnacle.
