Famous Peter Atkins Quotes

“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 doubtless scorn religion as sentimental wishful thinking. Would not that same uncluttered mind also see the attempts to reconcile science and religion by disparaging the reduction of the complex to the simple as attempts guided by muddle-headed sentiment and intellectually dishonest emotion? ...Religion closes off the central questions of existence by attempting to dissuade us from further enquiry by asserting that we cannot ever hope to comprehend. We are, religion asserts, simply too puny. Through fear of being shown to be vacuous, religion denies the awesome power of human comprehension. It seeks to thwart, by encouraging awe in things unseen, the disclosure of the emptiness of faith. Religion, in contrast to science, deploys the repugnant view that the world is too big for our understanding. Science, in contrast to religion, opens up the great questions of being to rational discussion, to discussion with the prospect of resolution and elucidation. Science, above all, respects the power of the human intellect. Science is the apotheosis of the intellect and the consummation of the Renaissance. Science respects more deeply the potential of humanity than religion ever can.”

“The first law is essentially based on the conservation of energy, the fact that energy can be neither created nor destroyed. Conservation laws—laws that state that a certain property does not change—have a very deep origin, which is one reason why scientists, and thermodynamicists in particular, get so excited when nothing happens. There is a celebrated theorem, Noether’s theorem, proposed by the German mathematician Emmy Noether (1882–1935), which states that to every conservation law there corresponds a symmetry. Thus, conservation laws are based on various aspects of the shape of the universe we inhabit. In the particular case of the conservation of energy, the symmetry is that of the shape of time. Energy is conserved because time is uniform: time flows steadily, it does not bunch up and run faster then spread out and run slowly. Time is a uniformly structured coordinate. If time were to bunch up and spread out, energy would not be conserved. Thus, the first law of thermodynamics is based on a very deep aspect of our universe and the early thermodynamicists were unwittingly probing its shape.”

“Without chorophyll, the world would be a damp warm rock instead of the softly green haven of life that we know, for chlorphyll holds its magnesium eye to the sun and captures the energy of sunlight, in the first step of photosynthesis. For reasons we shall explore, magnesium has exactly the right features to make this process possible. Had the kingdom lacked this element, chlorophyll;’s eye would have been blind, phtosynthesis would not take place, and life as we know it would not exist.”

“We are within a whisper of arriving at the first law. Suppose we have a closed system and use it to do some work or allow a release of energy as heat. Its internal energy falls. We then leave the system isolated from its surroundings for as long as we like, and later return to it. We invariably find that its capacity to do work—its internal energy—has not been restored to its original value. In other words, the internal energy of an isolated system is constant. That is the first law of thermodynamics, or at least one statement of it, for the law comes in many equivalent forms. Another universal law of nature, this time of human nature, is that the prospect of wealth motivates deceit. Wealth—and untold benefits to humanity—would accrue to an untold extent if the first law were found to be false under certain conditions. It would be found to be false if work could be generated by an adiabatic, closed system without a diminution of its internal energy. In other words, if we could achieve perpetual motion, work produced without consumption of fuel. Despite enormous efforts, perpetual motion has never been achieved. There have been claims galore, of course, but all of them have involved a degree of deception. Patent offices are now closed to the consideration of all such machines, for the first law is regarded as unbreakable and reports of its transgression not worth the time or effort to pursue. There are certain instances in science, and certainly in technology, where a closed mind is probably justified.”

“Then there is the extraordinary marriage of observation and mathematics. Mankind, and for some perhaps sociological reason it has been mostly man kind, has developed a sinewy language of the utmost rigour and austerity that has proved to be the perfect tool for teasing out objectively the consequences of an imaginative qualitative leap or of adding spine to a whim so that it can stand up to the harshness of quantitative comparison of prediction with observation. I hasten to add that mathematics does not appear explicitly in this book, but it does lie as a hidden deep foundation beneath it.”

“In preparation for our journey in which we shall nose around among the myths that a collaboration of ignorance and deep concern have jointly inspired, I would like to establish in broad terms my vision of the nature and limitations, if any, of the scientific method. I suspect that few would disagree that science is competent when it comes to the fabrication of novel stuff and novel applications of stuff in general. That, I believe, is not an issue to delay us. Nor shall I linger on the argument about whether these novel stuffs, including better medicines, better and more abundant foods, better fabrics, better modes of communication and transport, better modes of entertainment, and so on, weighed against the social costs, including better ways of killing, injuring our environment, and accidentally or intentionally maiming, add overall to the sum of human happiness. I focus instead on the ability of the scientific method to illuminate matters of great human concern and drive out ignorance while retaining wonder.”

“A great deal of the universe does not need any explanation. Elephants, for instance. Once molecules have learnt to compete and to create other molecules in their own image, elephants, and things resembling elephants, will in due course be found roaming around the countryside ... Some of the things resembling elephants will be men.”
