Innovation comes out of great human ingenuity and very personal passions.

The American government will be whatever we all make of it.

I have been able to attend many technology conferences around the world over the years, including some of the largest, like Google I/O, Microsoft's Developer Conference, Apple's WorldWide Developers Conference, Oracle World, Le Web, and more.

I think open source is an evolutionary idea for humanity, this idea of transparency. It played out for us in the technology world, but it also played out with the idea of a truth and reconciliation commission and Wikipedia.

Flipping our classrooms into active learning spaces really is important and having these convenient spaces where people feel comfortable.

Nothing is less important than which fork you use. Etiquette is the science of living. It embraces everything. It is ethics. It is honor.

There is a fifth dimension, beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition.

Imagination... its limits are only those of the mind itself.

I don't believe there's anything in life you can't go back and fix. The ancient Vedas - the oldest Hindu philosophy - and modern science agree that time is an illusion. If that's true, there's no such thing as a past or a future - it's all one huge now. So what you fix now affects the past and the future.

NI love watching science fiction because I feel like when it's done well, it's not just monsters, but philosophy. Really good science fiction like, '2001,' for example, or the first 'Matrix.' But it takes someone who's got a brain and thinks in order to do really good science fiction.

At a time when science plays such a powerful role in the life of society, when the destiny of the whole of mankind may hinge on the results of scientific research, it is incumbent on all scientists to be fully conscious of that role, and conduct themselves accordingly.

I have to bring to your notice a terrifying reality: with the development of nuclear weapons Man has acquired, for the first time in history, the technical means to destroy the whole of civilization in a single act.

Let me remind you that nuclear disarmament is not just an ardent desire of the people, as expressed in many resolutions of the United Nations. It is a legal commitment by the five official nuclear states, entered into when they signed the Non-Proliferation Treaty.

I think we learn from medicine everywhere that it is, at its heart, a human endeavor, requiring good science but also a limitless curiosity and interest in your fellow human being, and that the physician-patient relationship is key; all else follows from it.

I think we can see how blessed we are in America to have access to the kind of health care we do if we are insured, and even if uninsured, how there is a safety net. Now, as to the problem of how much health care costs and how we reform health care ... it is another story altogether.

The bottom line: health care reform is about the patient, not about the physician.

Though I am fascinated by knowledge, I am even more fascinated by wisdom.

Rituals, anthropologists will tell us, are about transformation. The rituals we use for marriage, baptism or inaugurating a president are as elaborate as they are because we associate the ritual with a major life passage, the crossing of a critical threshold, or in other words, with transformation.

The incredible cinematography makes 'A Walk to Beautiful' almost like a poem; there is a tenderness on display that seems to emanate from the camera. There is also great sensitivity to the women whose stories are being told - never did I have a sense of the subjects being exploited.

There are moments as a teacher when I'm conscious that I'm trotting out the same exact phrase my professor used with me years ago. It's an eerie feeling, as if my old mentor is not just in the room, but in my shoes, using me as his mouthpiece.

I love to read poetry but I haven't written anything that I'm willing to show anybody.

What we need in medical schools is not to teach empathy, as much as to preserve it - the process of learning huge volumes of information about disease, of learning a specialized language, can ironically make one lose sight of the patient one came to serve; empathy can be replaced by cynicism.

Students undergo a conversion in the third year of medical school - not pre-clinical to clinical, but pre-cynical to cynical.

Certainly when I got to medical school, I had role models of the kind of physicians I wanted to be. I had an uncle who, looking back, was probably not the most-educated physician around, but he carried it off so well.

We have the sense that medical students come to medicine with a great capacity to understand the suffering of patients. And then by the end of the third year they completely lose that ability, partly because we teach them the specialized language of medicine.

I think America is really in denial about the degree to which residents, particularly foreign medical graduates, man the county hospitals of this country, and but for their services, I'm not sure how exactly we could manage.

Literature is a beautiful way of keeping the imagination alive, of visiting worlds you would never have time to in your day-to-day life. It keeps you abreast of a wider spectrum of human activities.

Surgical Anatomy is, to the student of medicine and surgery, the most essential branch of anatomical science, having reference more especially to an accurate knowledge of the more important regions, and consisting in the application of anatomy generally to the practice of surgery.

In the imperfect records left of the anatomy of the ancient Egyptians, no trace of any knowledge of the spleen can be ascertained.

That's one of those things about being a computer science major: Valentine's Day is just another day.

Some say they see poetry in my paintings; I see only science.

It is not enough to know your craft - you have to have feeling. Science is all very well, but for us imagination is worth far more.

There are no lines in nature, only areas of colour, one against another.

You would hardly believe how difficult it is to place a figure alone on a canvas, and to concentrate all the interest on this single and universal figure and still keep it living and real.

I would kiss you, had I the courage.

Follow your passion, be prepared to work hard and sacrifice, and, above all, don't let anyone limit your dreams.

I think that every single person should play sports.

I'm Jamaican, man. I'm Jamaican first. You gotta understand that's where I'm from. That's home. That you can never take away from me. I'm a Jamaican-born Canadian sprinter.

Science, almost from its beginnings, has been truly international in character. National prejudices disappear completely in the scientist's search for truth.

The scientist is motivated primarily by curiosity and a desire for truth.

All science is either physics or stamp collecting.

Architecture is a science arising out of many other sciences, and adorned with much and varied learning; by the help of which a judgment is formed of those works which are the result of other arts.

For an object under the eye will appear very different from the same object placed above it; in an inclosed space, very different from the same in an open space.

Consistency is found in that work whose whole and detail are suitable to the occasion. It arises from circumstance, custom, and nature.

Science, as illustrated by the printing press, the telegraph, the railway, is a double-edged sword. At the same moment that it puts an enormous power in the hands of the good man, it also offers an equal advantage to the evil disposed.

An inspiration - a long, deep breath of the pure air of thought - could alone give health to the heart.

This sunlight linked me through the ages to that past consciousness.

The heart looks into space to be away from earth.

Science is a perception of the world around us. Science is a place where what you find in nature pleases you.

I am aware of the usefulness of science to society and of the benefits society derives from it.
