Think of the most fussy science teacher you ever had. The one who docked your grade if the sixth decimal place in your answer was rounded incorrectly; who tucked in his periodic table T-shirt, corrected every student who said "weight" when he or she meant "mass", and made everyone, including himself, wear goggles even while mixing sugar water. Now try to imagine someone whom your teacher would hate for being anal-retentive. That is the kind of person who works for a bureau of standards and measurement.

There, just beyond his open palm, was our mother’s face. I wasn’t expecting it. We hadn’t requested a viewing, and the memorial service was closed-coffin. We got it anyway. They’d shampooed and waved her hair and made up her face. They’d done a great job, but I felt taken, as if we’d asked for the basic carwash and they’d gone ahead and detailed her. Hey, I wanted to say, we didn’t order this. But of course I said nothing. Death makes us helplessly polite.

I'm comfortable with the unknown -- that's the point of science. There are places out there, billions of places out there, that we know nothing about. And the fact that we know nothing about them excites me, and I want to go out and find out about them.And that's what science is.So I think if you’re not comfortable with the unknown, then it’s difficult to be a scientist… I don’t need an answer. I don’t need answers to everything. I want to have answers to find.

We have been led to imagine all sorts of things infinitely more marvelous than the imagining of poets and dreamers of the past. It shows that the imagination of nature is far, far greater than the imagination of man. For instance, how much more remarkable it is for us all to be stuck-half of us upside down-by a mysterious attraction, to a spinning ball that has been swinging in space for billions of years, than to be carried on the back of an elephant supported on a tortoise swimming in a bottomless sea.

How can you say one thing when your data shows something else. One doesn't know what was on the authors' minds and maybe they interpreted things differently but the sense is that the literature maintains an attitude somewhat like the approach of lawyers. If the jury buys it, it doesn't matter whether or not it's true. In scientific publishing, the jury are the reviewers and the editors. If they are already convinced of the conclusion, if there is no voir dire, you will surely win the case.

Because you have seen something doesn't mean you can explain it. Differing interpretations will always abound, even when good minds come to bear. The kernel of indisputable information is a dot in space; interpretations grow out of the desire to make this point a line, to give it direction. The directions in which it can be sent, the uses to which it can be put by a culturally, professionally, and geographically diverse society are almost without limit. The possibilities make good scientists chary.

... Bundan on sene kadar önce bilim adamları varlığın bir enerji alanı yarattığını buldular. Deney şöyle oldu: Bir kaba bir DNA yerleştirildi. Üzerine elektron salındı. Elektronlar DNA'nın üzerlerindeki konumlarını aldılar. Az sonra o kaptan DNA çıkarıldı. Tekrar elektronlar salındı. DNA olmamasına rağmen elektronlar eski konumlarını aldılar...

We should not be too quick to dismiss our own [ocular] arrangement. As so often in biology, the situation is more complex.....we have the advantage that our own light-sensitive cells are embedded directly in their support cells (the retinal pigment epithelium) with an excellent blood supply immediately underneath. Such an arrangement supports the continuous turnover of photosensitive pigments. The human retina consumes even more oxygen than the brain, per gram, making it the most energetic organ in the body.

İdeoloji, doğası gereği etkin düşünceye de, etkin duyguya da çekici gelmez. İnsanı ya heyecanlandıran ya da uyutan hap gibidir. Hitler, Mein Kampfda (Kavgam'da) halkı toplayıp galeyana getirmek için en elverişli zamanın, insanların yorgun ve etkilenmeye açık olduğu akşam saatleri olduğunu söylerken bu noktayı açıkça gördüğünü belirtiyordu.

Perhaps in the back of our minds we already understand, without all the science I've discussed, that something terribly wrong is happening. Our sustenance now comes from misery. We know that if someone offers to show us a film on how our meat is produced, it will be a horror film. We perhaps know more than we care to admit, keeping it down in the dark places of our memory-- disavowed. When we eat factory-farmed meat we live, literally, on tortured flesh. Increasingly, that tortured flesh is becoming our own.

The child is more individualised than the adult, the patient more than the healthy man, the madman and the delinquent more than the normal and the non-delinquent. In each case, it is towards the first of these pairs that all the individualising mechanisms are turned in our civilisation and when one wishes to individualise the healthy, normal and law-abiding adult, it is always by asking him how much of the child he has in him, what secret madness lies within him, what fundamental crime he has dreamt of committing

In 1494, King Charles VIII of France invaded Italy. Within months, his army collapsed and fled. It was routed not by the Italian army but by a microbe. A mysterious new disease spread through sex killed many of Charles’s soldiers and left survivors weak and disfigured. French soldiers spread the disease across much of Europe, and then it moved into Africa and Asia. Many called it the French disease. The French called it the Italian disease. Arabs called it the Christian disease. Today, it is called syphilis.

Few scientists acquainted with the chemistry of biological systems at the molecular level can avoid being inspired. Evolution has produced chemical compounds exquisitely organized to accomplish the most complicated and delicate of tasks. Many organic chemists viewing crystal structures of enzyme systems or nucleic acids and knowing the marvels of specificity of the immune systems must dream of designing and synthesizing simpler organic compounds that imitate working features of these naturally occurring compounds.

We believe that information is an enlightening agent, but I can assure you it is not. We consume information, but we can’t read. We forgot how to sit down and engage the dense layers of a text. We are so busy devouring information that we forgot how to dance with ideas. We confuse linguistic bits of data for knowledge and ideas. I can assure you, gentlemen, they are not the same. Ideas require effort and the kind of sensibility that engages the subtle layers of meaning. What the hell does information require?

If my nightmare is a culture inhabited by posthumans who regard their bodies as fashion accessories rather than the ground of being, my dream is a version of the posthuman that embraces the possibilities of information technologies without being seduced by fantasies of unlimited power and disembodied immortality, that recognizes and celebrates finitude as a condition of human being, and that understands human life is embedded in a material world of great complexity, one on which we depend for our continued survival.
