The celebration feels great, but it will be very brief because before we start our main science phase, we still have six months of challenging work to adjust the orbit to the right size and...

Most importantly, I’d learned how to question and why (“when” had never been an issue: always).

Nature, … in order to carry out the marvelous operations [that occur] in animals and plants has been pleased to construct their organized bodies with a very large number of machines, which are of necessity...

The task of the modern era was the realization and humanization of God – the transformation and dissolution of theology into anthropology.

We could undoubtedly survive on these rations a lot longer than we’d care to live.” (NASA went ahead and tested an all-milkshake meal plan on groups of college students living in a simulated space capsule...

His [Faraday’s] third great discovery is the Magnetization of Light, which I should liken to the Weisshorn among mountains-high, beautiful, and alone.

Now You Know!

Do not judge others, without first judging yourself. There is no strength without knowing thyself. ☥

Reality provides us with facts so romantic that imagination itself could add nothing to them.

I myself find the division of the world into an objective and a subjective side much too arbitrary. The fact that religions through the ages have spoken in images, parables, and paradoxes means simply that...

Intelligent Design is a remarkably uncreative theory that abandons the search for understanding at the very point where it is most needed. If Intelligent Design is really a science, then the burden is on its...

I suspect that scientists are driven by the sense that the world out there – reality – contains a hidden order, and the scientist is trying to elucidate the hidden order in our reality. And...

The Gobi wasn’t completely devoid of life; its ecosystem was unexpectedly extensive and varied given the extremes to which it subjected its denizens, but some of those forms of life weren’t the kind that Anna...

The scientific method,” Thomas Henry Huxley once wrote, “is nothing but the normal working of the human mind.” That is to say, when the mind is working; that is to say further, when it is...

Plato was the first to envisage the idea of timeless existence and to emphasize it—against reason—as a reality, more [real] than our actual experience…

Now, almost one hundred years later, it is difficult to fully appreciate how much our picture of the universe has changed in the span of a single human lifetime. As far as the scientific community...

We have come to look at our planet as a resource for our species, which is funny when you think that the planet has been around for about five billion years, and Homo sapiens for...

I was aware of Darwin’s views fourteen years before I adopted them and I have done so solely and entirely from an independent study of the plants themselves.[Letter to W.H. Harvey]

The lives of scientists, considered as Lives, almost always make dull reading. For one thing, the careers of the famous and the merely ordinary fall into much the same pattern, give or take an honorary...

Are you really surprised by the endurance of religion? What ideology is likely to be more durable than one that conforms, at every turn, to our powers of wishful thinking? Hope is easy; knowledge is...

Kepler’s laws, although not rigidly true, are sufficiently near to the truth to have led to the discovery of the law of attraction of the bodies of the solar system. The deviation from complete accuracy...

But recently I have learned from discussions with a variety of scientists and other non-philosophers (e.g., the scientists participating with me in the Sean Carroll workshop on the future of naturalism) that they lean the...

The mind is matter in and of itself, but I don’t mind, and it doesn’t matter.

The aim of science is to make difficult things understandable in a simpler way; the aim of poetry is to state simple things in an incomprehensible way. The two are incompatible.

To create something new, knowledge is essentially required, but not academic degree.

…since the order of the world is shaped by death, mightn’t it be better for God if we refuse to believe in Him and struggle with all our might against death, without raising our eyes...

There are still many unsolved problems about bird life, among which are the age that birds attain, the exact time at which some birds acquire their adult dress, and the changes which occur in this...

Those whose acquaintance with scientific research is derived chiefly from its practical results easily develop a completely false notion of the mentality of the men who, surrounded by a skeptical world, have shown the way...

Tapestries are made by many artisans working together. The contributions of separate workers cannot be discerned in the completed work, and the loose and false threads have been covered over. So it is in our...

After the discovery of spectral analysis no one trained in physics could doubt the problem of the atom would be solved when physicists had learned to understand the language of spectra. So manifold was the...

Maybe scientists are fundamentalist when it comes to defining in some abstract way what is meant by ‘truth’. But so is everybody else. I am no more fundamentalist when I say evolution is true than...

Most people, when directly confronted by evidence that they are wrong, do not change their point of view or course of action but justify it even more tenaciously. Even irrefutable evidence is rarely enough to...

Science is a tool of Common Sense. When we insist that all valid information come from science or doctors, Common Sense becomes uncommon or lost forever.

We must pass through the darkness, to reach the light.

Dragons and Afterlife .. I don’t see any difference between both of them, we didn’t see neither the dragons nor afterlife, we just heard about them and both of them are superstitions with no scientific...

My own experience of over 60 years in biomedical research amply demonstrated that without the use of animals and of human beings, it would have been impossible to acquire the important knowledge needed to prevent...

I don’t mind not knowing. It doesn’t scare me.

We must trust to nothing but facts: These are presented to us by Nature, and cannot deceive. We ought, in every instance, to submit our reasoning to the test of experiment, and never to search...

Life would be tragic if it weren’t funny.

Science is not about making predictions or performing experiments. Science is about explaining.

Those distinct substances, which concretes generally either afford, or are made up of, may, without very much inconvenience, be called the elements or principles of them.

Once in a while a new government initiates a program to put power to better use, but its success or failure never really proves anything. In science, experiments are designed, checked, altered, repeated– but not...

I profess to learn and to teach anatomy not from books but from dissections, not from the tenets of Philosophers but from the fabric of Nature.

In honoring the Wright Brothers, it is customary and proper to recognize their contribution to scientific progress. But I believe it is equally important to emphasize the qualities in their pioneering life and the character...

There are two kinds of truth; The truth that lights the way and the truth that warms the heart. The fist of these is science and the second is art.

The late Alan Gregg pointed out that human population growth within the ecosystem was closely analogous to the growth of malignant tumor cells within an organism: that man was acting like a cancer on the...

Theism, as religious people typically hold it, does not merely state that some entity created the universe, but that the universe was created specifically with humans in mind as the most important part of creation....

He was the least spiritual of all the monks here, accepting nothing without proof. This skepticism was simultaneously his greatest asset and his greatest impediment.

Someone with a fresh mind, one not conditioned by upbringing and environment, would doubtless look at science and the powerful reductionism that it inspires as overwhelmingly the better mode of understanding the world, and would...

If thinking in the sense of intellection were the same as judging, for example, it would not be possible to think without judgment. We would not be able to accept a judgment without thinking because...
