Experiment Quotes

“[At the beginning of modern science], a light dawned on all those who study nature. They comprehended that reason has insight only into what it itself produces according to its own design; that it must take the lead with principles for its judgments according to constant laws and compel nature to answer its questions, rather than letting nature guide its movements by keeping reason, as it were, in leading-strings; for otherwise accidental observations, made according to no previously designed plan, can never connect up into a necessary law, which is yet what reason seeks and requires. Reason, in order to be taught by nature, must approach nature with its principles in one hand, according to which alone the agreement among appearances can count as laws, and, in the other hand, the experiments thought in accordance with these principles - yet in order to be instructed by nature not like a pupil, who has recited to him whatever the teacher wants to say, but like an appointed judge who compels witnesses to answer the questions he puts to them. Thus even physics owes the advantageous revolution in its way of thinking to the inspiration that what reason would not be able to know of itself and has to learn from nature, it has to seek in the latter (though not merely ascribe to it) in accordance with what reason itself puts into nature. This is how natural science was first brought to the secure course of a science after groping about for so many centuries.”

“Yes, I'm a materialist. I'm willing to be shown wrong, but that has not happened — yet. And I admit that the reason I'm unable to accept the claims of psychic, occult, and/or supernatural wonders is because I'm locked into a world-view that demands evidence rather than blind faith, a view that insists upon the replication of all experiments — particularly those that appear to show violations of a rational world — and a view which requires open examination of the methods used to carry out those experiments.”

“That all plants immediately and substantially stem from the element water alone I have learnt from the following experiment. I took an earthern vessel in which I placed two hundred pounds of earth dried in an oven, and watered with rain water. I planted in it a willow tree weighing five pounds. Five years later it had developed a tree weighing one hundred and sixty-nine pounds and about three ounces. Nothing but rain (or distilled water) had been added. The large vessel was placed in earth and covered by an iron lid with a tin-surface that was pierced with many holes. I have not weighed the leaves that came off in the four autumn seasons. Finally I dried the earth in the vessel again and found the same two hundred pounds of it diminished by about two ounces. Hence one hundred and sixty-four pounds of wood, bark and roots had come up from water alone. (1648) [A diligent experiment that was quantitatively correct only as far as it goes. He overlooked the essential role of air and photosynthesis in the growth process]”

“Should the research worker of the future discover some means of releasing this [atomic] energy in a form which could be employed, the human race will have at its command powers beyond the dream of scientific fiction, but the remotest possibility must always be considered that the energy once liberated will be completely uncontrollable and by its intense violence detonate all neighbouring substances. In this event, the whole of the hydrogen on earth might be transformed at once and the success of the experiment published at large to the universe as a new star.”

“Data that did not fit the commonly accepted assumptions of a discipline would either be discounted or explained away for as long as possible. The more contradictions accumulated, the more convoluted the rationalizations became. 'In science, as in the playing card experiment, novelty emerges only with difficulty,' Kuhn wrote. But then, finally, someone came along who was willing to call a red spade a red spade. Crisis led to insight, and the old framework gave way to a new one. This is how great scientific discoveries or, to use the term Kuhn made so popular, 'paradigm shifts' took place.”

“To understand this new frontier, I will have to try to master one of the most difficult and counterintuitive theories ever recorded in the annals of science: quantum physics. Listen to those who have spent their lives immersed in this world and you will have a sense of the challenge we face. After making his groundbreaking discoveries in quantum physics, Werner Heisenberg recalled, "I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?" Einstein declared after one discovery, "If it is correct it signifies the end of science." Schrödinger was so shocked by the implications of what he'd cooked up that he admitted, "I do not like it and I am sorry I had anything to do with it." Nevertheless, quantum physics is now one of the most powerful and well-tested pieces of science on the books. Nothing has come close to pushing it off its pedestal as one of the great scientific achievements of the last century. So there is nothing to do but to dive headfirst into this uncertain world. Feynman has some good advice for me as I embark on my quest: "I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possibly avoid it, 'But how can it be like that?' because you will get 'down the drain,' into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.”

“The USA government encourages gun ownership at the same time as they have allowed environmental radiation levels to become ridiculously high powered and this continues to increase annually. It will be interesting to see where this government experiment eventually takes the USA!”

“There is a time and place for electromagnetic shielding and I regard it as a last resort due to the long term biological problems that I have observed with it over the years in plant growth experiments.”

“About eight days ago I discovered that sulfur in burning, far from losing weight, on the contrary, gains it; it is the same with phosphorus; this increase of weight arises from a prodigious quantity of air that is fixed during combustion and combines with the vapors. This discovery, which I have established by experiments, that I regard as decisive, has led me to think that what is observed in the combustion of sulfur and phosphorus may well take place in the case of all substances that gain in weight by combustion and calcination; and I am persuaded that the increase in weight of metallic calyxes is due to the same cause... This discovery seems to me one of the most interesting that has been made since Stahl and since it is difficult not to disclose something inadvertently in conversation with friends that could lead to the truth I have thought it necessary to make the present deposit to the Secretary of the Academy to await the time I make my experiments public.”

“I followed the other Experiment around, yesterday afternoon, at a distance, to see what it might be for, if I could. But I was not able to make [it] out. I think it is a man. I had never seen a man, but it looked like one, and I feel sure that that is what it is. I realize that I feel more curiosity about it than about any of the other reptiles. If it is a reptile, and I suppose it is; for it has frowzy hair and blue eyes, and looks like a reptile. It has no hips; it tapers like a carrot; when it stands, it spreads itself apart like a derrick; so I think it is a reptile, though it may be architecture.”

“Before an experiment can be performed, it must be planned—the question to nature must be formulated before being posed. Before the result of a measurement can be used, it must be interpreted—nature's answer must be understood properly. These two tasks are those of the theorist, who finds himself always more and more dependent on the tools of abstract mathematics. Of course, this does not mean that the experimenter does not also engage in theoretical deliberations. The foremost classical example of a major achievement produced by such a division of labor is the creation of spectrum analysis by the joint efforts of Robert Bunsen, the experimenter, and Gustav Kirchhoff, the theorist. Since then, spectrum analysis has been continually developing and bearing ever richer fruit.”

“It's something, it can be nothing. I don't know its name, so I call it magic. I've never seen a sunrise, but Mary and Dickon have, and for what they tell me, I'm sure that is magic, too. Something pushes it up and draws it. Sometimes since I've been in the garden I've looked I've looked up through the trees at the sky and I have had a strange feeling of being happy as if something were pushing and drawing in my chest and making me breathe fast. Magic is always pushing and drawing and making things out of nothing. Everything is made out of Magic, leaves and trees, flowers and birds, badgers and foxes and squirrels and people. So it must be all around us. In this garden--in all the places. The Magic in this garden has made me stand up and know I am going to live to be a man. I am going to make the scientific experiment of trying to get some and put it in myself and make it push and draw me and make me strong. I don't know how to do it but I think that if you keep thinking about it and calling it perhaps it will come. Perhaps that is the first baby way to get it. When I was going to try to stand that first time Mary kept saying to herself as fast as she could, `You can do it! You can do it!' and I did. I had to try myself at the same time, of course, but her Magic helped me-and so did Dickon's. Every morning and evening and as often in the daytime as I can remember I am going to say, 'Magic is in me! Magic is making me well! I am going to be as strong as Dickon, as strong as Dickon!' And you must all do it, too. That is my experiment Will you help, Ben Weatherstaff?”

“A small bubble of air remained unabsorbed... if there is any part of the phlogisticated air [nitrogen] of our atmosphere which differs from the rest, and cannot be reduced to nitrous acid, we may safely conclude that it is not more than 1/120 part of the whole. [Cavendish did not realize the significance of the remaining small bubble. Not until a century later were the air’s Noble Gases appreciated.]”

“Men have before hired bravos to transact their crimes, while their own person and reputation sat under shelter. I was the first that ever did so for his pleasure. I was the first that could plod in the public eye with a load of genial respectability, and in a moment, like a schoolboy, strip off these lendings and spring headlong into the sea of liberty.”
