Constrained optimization is the art of compromise between conflicting objectives. This is what design is all about. To find fault with biological design - as Stephen Jay Gould regularly does - because it misses some idealized optimum is therefore gra...
Imagine a life-form whose brainpower is to ours as ours is to a chimpanzee’s. To such a species, our highest mental achievements would be trivial. Their toddlers, instead of learning their ABCs on Sesame Street, would learn multivariable calculus o...
Some molecules - ammonia, carbon dioxide, water - show up everywhere in the universe, whether life is present or not. But others pop up especially in the presence of life itself. Among the biomarkers in Earth's atmosphere are ozone-destroying chlorof...
Every night we stopped in a cabin where wood had been stacked, matches left, and canned goods laid out for the chance traveler. All the unknown host received in return was a scribbled note giving our thanks, any news we could think of, and our names....
We do not belong to this material world that science constructs for us. We are not in it; we are outside. We are only spectators. The reason why we believe that we are in it, that we belong to the picture, is that our bodies are in the picture. Our b...
Two men who had never seen each other before and would not likely see each other again. But their sincerity and sweetness, their sharing an instant in a fleeting life. It was almost as if a secret had passed between them. Was this some kind of love? ...
In the world of the very small, where particle and wave aspects of reality are equally significant, things do not behave in any way that we can understand from our experience of the everyday world...all pictures are false, and there is no physical an...
Today, Aaron decided, he would begin to grieve in earnest. He would walk the lonely beach, mocked by gulls, uncaring, his every step a stately rebuke to the malign forces that had blighted his fate. His was the tragedy of a man who couldn't have his ...
And suddenly, in the place of the woman-shape made of shadow, there was something else. Something huge, something ugly. Linay flung up both hands. The thing screamed like a hawk and opened to wings: one white as a death cap, one clotted in shadow. Th...
Suddenly, over the slope, as if tethered to a cord of air drawing quickly upward, came a Northern Harrier, motionless but for its rising. So still was the bird - wings, tail, head - it might have been a museum specimen. Then, as if atop the wind, it ...
Whatever the reason we first mustered the _Apollo_ program, however mired it was in Cold War nationalism and the instruments of death, the inescapable recognition of the unity and fragility of the Earth is its clear and luminous dividend, the unexpec...
All terrible things are more terrible if they give us no chance of retrieving a blunder—either no chance at all, or only one that depends on our enemies and not ourselves. Those things are also worse which we cannot, or cannot easily, help. Speakin...
The truth is that, just as in the other imitative arts one imitation is always of one thing, so in poetry the story, as an imitation of action, must represent one action, a complete whole, with its several incidents so closely connected that the tran...
Hawke continued to walk beside his lieutenant— a man who, as a result of his incredible feats during the battle in San Francisco, now had a fan club. Complete with “I (heart) Judd” and “Judd Is My Boyfriend” memorabilia. In the normal cours...
...[D]ivision of labor, in my mind, is one of the dangers of work-based technology. Modern IT infrastructure allows us to break projects into very small, discrete parts and assign each person to do only one of the many parts. In so doing, companies r...
To summarize, using money to motivate people can be a double-edged sword. For tasks that require cognitive ability, low to moderate performance-based incentives can help. But when the incentive level is very high, it can command too much attention an...
If we wish to draw philosophical conclusions about our own existence, our significance, and the significance of the universe itself, our conclusions should be based on empirical knowledge. A truly open mind means forcing our imaginations to conform t...
I’m much better at working out ideas in action than I am in theorizing about it and then transferring my thinking to action. I don’t work that way. I work with tentative ideas and I experiment and then with that experimentation in action, I final...
When people criticize me for not having any respect for existing structures and institutions, I protest. I say I give institutions and structures and traditions all the respect that I think they deserve. That's usually mighty little, but there are th...
Science enhances the moral value of life, because it furthers a love of truth and reverence—love of truth displaying itself in the constant endeavor to arrive at a more exact knowledge of the world of mind and matter around us, and reverence, becau...
Dying was nothing and he had no picture of it nor fear of it in his mind. But living was a field of grain blowing in the wind on the side of a hill. Living was a hawk in the sky. Living was an earthen jar of water in the dust of the threshing with th...
