Nitrogen Cycle Quotes

Grief is an element. It has its own cycle like the carbon cycle, the nitrogen. It never diminishes not ever. It passes in and out of everything.

I want to end my life like a human being: in Intensive Care, high on morphine, surrounded by cripplingly expensive doctors and brutal, relentless life-support machines. Then the corpse can go into orbit—preferably around the sun. I don't care how much it costs, just so long as I don't end up party of any fucking natural cycle: carbon, phosphorus, nitrogen. Gaia, I divorce thee. Go suck the nutrients out of someone else, you grasping bitch.

I think of two landscapes- one outside the self, the other within. The external landscape is the one we see-not only the line and color of the land and its shading at different times of the day, but also its plants and animals in season, its weather, its geology… If you walk up, say, a dry arroyo in the Sonoran Desert you will feel a mounding and rolling of sand and silt beneath your foot that is distinctive. You will anticipate the crumbling of the sedimentary earth in the arroyo bank as your hand reaches out, and in that tangible evidence you will sense the history of water in the region. Perhaps a black-throated sparrow lands in a paloverde bush… the smell of the creosote bush….all elements of the land, and what I mean by “the landscape.” The second landscape I think of is an interior one, a kind of projection within a person of a part of the exterior landscape. Relationships in the exterior landscape include those that are named and discernible, such as the nitrogen cycle, or a vertical sequence of Ordovician limestone, and others that are uncodified or ineffable, such as winter light falling on a particular kind of granite, or the effect of humidity on the frequency of a blackpoll warbler’s burst of song….the shape and character of these relationships in a person’s thinking, I believe, are deeply influenced by where on this earth one goes, what one touches, the patterns one observes in nature- the intricate history of one’s life in the land, even a life in the city, where wind, the chirp of birds, the line of a falling leaf, are known. These thoughts are arranged, further, according to the thread of one’s moral, intellectual, and spiritual development. The interior landscape responds to the character and subtlety of an exterior landscape; the shape of the individual mind is affected by land as it is by genes. Among the Navajo, the land is thought to exhibit sacred order…each individual undertakes to order his interior landscape according to the exterior landscape. To succeed in this means to achieve a balanced state of mental health…Among the various sung ceremonies of this people-Enemyway, Coyoteway, Uglyway- there is one called Beautyway. It is, in part, a spiritual invocation of the order of the exterior universe, that irreducible, holy complexity that manifests itself as all things changing through time (a Navajo definition of beauty).

The formula presents a symbol of the self, for the self is not just a static quantity or constant form, but is also a dynamic process. In the same way, the ancients saw the imago Dei in man not as a mere imprint, as a sort of lifeless, stereotyped impression, but as an active force. The four transformations represent a process of restoration or rejuvenation taking place, as it were, inside the self, and comparable to the carbon-nitrogen cycle in the sun, when a carbon nucleus captures four protons (two of which immediately become neutrons) and releases them at the end of the cycle in the form of an alpha particle. The carbon nucleus itself comes out of the reaction unchanged, “like the Phoenix from the ashes.”108 The secret of existence, i.e., the existence of the atom and its components, may well consist in a continually repeated process of rejuvenation, and one comes to similar conclusions in trying to account for the numinosity of the archetypes.

In 1969, NASA scientist James Lovelock noticed something unusual happening in the earth’s atmosphere: inexplicably, its balance of oxygen and other gases was regulating itself like a thermostat. But what was doing the regulating? He looked at other planetary processes—including the stable concentration of ocean salinity and the cycling of nutrients—and came to a startling conclusion: the earth is alive. He proposed that the earth is a superorganism—one giant living system that includes not just animals and plants but rocks, gases, and soil—acting together as if the planet was a single living being. Its bodily systems, such as the water cycle and nitrogen cycle, are balanced to maintain life on earth. The throb of the tides was the systole and diastole of the earth, and water coursed like blood through its veins. We proud humans may simply be microbes on the surface of a superbeing whose entirety we cannot fully comprehend. Like the bacteria in our body, is it possible that we, too, are part of a larger living earth, a speck on the eyeball of the universe? Tree roots break the sidewalk. Dandelions spring through the cracks. Insects grow resistant to pesticides

Only a few components of our atmosphere are greenhouse gases, which absorb infrared photons. The three most important are (in order) water vapor, carbon dioxide, and methane. Nitrogen, oxygen, and argon, which make up approximately 99.9% of the dry atmosphere, are not greenhouse gases. • The carbon cycle describes how carbon cycles through its primary reservoirs: the atmosphere (containing 100 GtC), land biosphere (2,000 GtC), ocean (1,000 GtC in

As animals died, the plains were scattered with the torn carcasses left by carrion feeders. Quickly, the skeletons, bleached and burned by ultraviolet light, once again became part of the whirling waltz of ecology. This was one of the great insights of ancient Greece: the world’s energy as Heraclitean fire, part of a closed system, from sky to stones, from grass to flesh, from flesh to earth, under the watchful eye of the sun that offered its photons to the nitrogen cycle. The Bardo Thodol—the Tibetan Book of the Dead—offers a similar theory to that of Heraclitus and the philosophers of flux. Everything passes, everything flows, the wild donkeys run, the wolves hunt, the vultures hover: order, equilibrium, under the sun. A crushing silence. An unforgiving light, few men. A dream.

By 1942 the Cornell physicist had established himself as a theoretician of the first rank. His most outstanding contribution, for which he would receive the 1967 Nobel Prize in Physics, was to elucidate the production of energy in stars, identifying a cycle of thermonuclear reactions involving hydrogen, nitrogen and oxygen that is catalyzed by carbon and culminates in the creation of helium.

This book is a compilation of interesting ideas that have strongly influenced my thoughts and I want to share them in a compressed form. That ideas can change your worldview and bring inspiration and the excitement of discovering something new. The emphasis is not on the technology because it is constantly changing. It is much more difficult to change the accompanying circumstances that affect the way technological solutions are realized. The chef did not invent salt, pepper and other spices. He just chooses good ingredients and uses them skilfully, so others can enjoy his art. If I’ve been successful, the book creates a new perspective for which the selection of ingredients is important, as well as the way they are smoothly and efficiently arranged together. In the first part of the book, we follow the natural flow needed to create the stimulating environment necessary for the survival of a modern company. It begins with challenges that corporations are facing, changes they are, more or less successfully, trying to make, and the culture they are trying to establish. After that, we discuss how to be creative, as well as what to look for in the innovation process. The book continues with a chapter that talks about importance of inclusion and purpose. This idea of inclusion – across ages, genders, geographies, cultures, sexual orientation, and all the other areas in which new ways of thinking can manifest – is essential for solving new problems as well as integral in finding new solutions to old problems. Purpose motivates people for reaching their full potential. This is The second and third parts of the book describes the areas that are important to support what is expressed in the first part. A flexible organization is based on IT alignment with business strategy. As a result of acceleration in the rate of innovation and technological changes, markets evolve rapidly, products’ life cycles get shorter and innovation becomes the main source of competitive advantage. Business Process Management (BPM) goes from task-based automation, to process-based automation, so automating a number of tasks in a process, and then to functional automation across multiple processes andeven moves towards automation at the business ecosystem level. Analytics brought us information and insight; AI turns that insight into superhuman knowledge and real-time action, unleashing new business models, new ways to build, dream, and experience the world, and new geniuses to advance humanity faster than ever before. Companies and industries are transforming our everyday experiences and the services we depend upon, from self-driving cars, to healthcare, to personal assistants. It is a central tenet for the disruptive changes of the 4th Industrial Revolution; a revolution that will likely challenge our ideas about what it means to be a human and just might be more transformative than any other industrial revolution we have seen yet. Another important disruptor is the blockchain - a distributed decentralized digital ledger of transactions with the promise of liberating information and making the economy more democratic. You no longer need to trust anyone but an algorithm. It brings reliability, transparency, and security to all manner of data exchanges: financial transactions, contractual and legal agreements, changes of ownership, and certifications. A quantum computer can simulate efficiently any physical process that occurs in Nature. Potential (long-term) applications include pharmaceuticals, solar power collection, efficient power transmission, catalysts for nitrogen fixation, carbon capture, etc. Perhaps we can build quantum algorithms for improving computational tasks within artificial intelligence, including sub-fields like machine learning. Perhaps a quantum deep learning network can be trained more efficiently, e.g. using a smaller training set. This is still in conceptual research domain.

chapters, a human nitrogen cycle has been identified. This pathway, termed entero-salivary nitrate-nitrite-nitric oxide pathway, can positively affect nitric oxide production and represents a potential symbiotic relationship between oral bacteria and their human hosts—meaning that the bacteria are performing essential metabolic steps that we as humans cannot perform. As a result, both the bacteria

The nitrogen cycle is a kind of miracle. The nitrogen cycle requires bears. Brown bears catch salmon in streams and rivers. Then the brown bears carry the salmon farther inland, and they bury these nitrogen-rich fish in the ground for later retrieval. But bears have short memories, and often they forget the fish where they left them, far inland from the streams. And the fish bodies decompose, leaving a reservoir of nitrogen in the ground. This creates a rich and fertile environment for large trees to grow, and in fact without the nitrogen deposited by the bears, very large old-growth trees would probably never have been able to continue their growth cycle. Five hundred years ago, if someone had removed all bears, none of the old-growth trees we have now would have grown.

We might be excused our ignorance in this case, because ocean-atmosphere systems are, after all, almost inconceivably complex. Less easy to excuse is our astounding lack of knowledge of much more visible features of our planet’s natural resources and ecology—features that have a direct impact on our well-being. For instance, we know surprisingly little about the state of the planet’s soils. While we have good information for some areas, like the Great Plains of the United States, soil data are sketchy for vast tracts of Africa, Asia, and Latin America, where billions of people depend directly on agriculture for survival. So we can’t accurately judge how badly we’ve degraded these soils through overuse and poor husbandry, though we do have patchy evidence that the damage is severe and getting worse in many places.18 Similarly, despite extensive satellite photography, our estimates of the rate and extent of tropical deforestation are rudimentary. We know even less about the natural ecology and species diversity inside these forests, where biologists presume most animal and plant species live. As a result, credible figures on the number of Earth’s species range from 5 to 30 million.19 And when it comes to broader questions—questions of how all these components of the planet’s ecology fit together; how they interact to produce Earth’s grand cycles of energy, carbon, oxygen, nitrogen, and sulfur; and how we’re perturbing these components and cycles—we find a deep and pervasive lack of knowledge, with unknown unknowns everywhere. Our ignorance, for all practical purposes, knows no bounds.

The present day is marked by pervasive environmental changes that are clear in almost every geological deposit, whether glacier ice, stalagtites, or sediments from lake-beds or the ocean floor. From spherical carbonaceous particles to microplastics to changes in the carbon and nitrogen cycles indicated by the changing levels of certain carbon and nitrogen isotopes, a human fingerprint is obvious.

[A] group of leading academics argue that humanity must stay within defined boundaries for a range of essential Earth-system processes to avoid catastrophic environmental change. . . . They propose that for three of these—the nitrogen cycle, the rate of loss of species and anthropogenic climate change—the maximum acceptable limit has already been transgressed. In addition, they say that humanity is fast approaching the boundaries for freshwater use, for converting forests and other natural ecosystems to cropland and urban areas, and for acidification of the oceans. Crossing even one of these planetary boundaries would risk triggering abrupt or irreversible environmental changes that would be very damaging or even catastrophic for society.

The carbon cycle has grabbed the headlines, but we’ve also seized hold of many other major geochemical cycles. Through production of fertilizers, we’ve radically altered Earth’s nitrogen cycle. The sulfur cycle has become dominated by industrial emissions. We’ve dammed rivers so thoroughly that there is now more than five times as much fresh water captured in reservoirs as there is remaining in all the wild rivers and streams of Earth! That is not a minor change. It’s fair to say that we’ve domesticated a major part of the water cycle of this planet. Earth’s vibrant hydrosphere, arguably our planet’s most distinctive feature, has to some degree become an artifact of human civilization. Every year now, humans constructing roads, buildings, and farms displace ten times more dirt than the combined erosive forces of wind, rain, earthquakes, and tides. Simply measured by the amount of stuff we move around, we have become the undisputed world heavyweight champions

What is it really that makes Earth Earth? The surface, where we live, exists at the interface between two giant heat engines: below us the churning mantle, above us the restless, windy troposphere. All rocky worlds large enough to hold an atmosphere will have some combination of these, and the dynamic possibilities of each realm have been substantially illuminated by the variations we’ve found on other worlds. We live on the convoluted, shifting shoreline between cycles of earth and sky that are incessantly driven by the Sun above and the heat below. So much about our world can be understood as the interplay between these inner and outer cycles. Life thrives at the boundary, enabled and sustained by the great cyclic flows of carbon, nitrogen, oxygen, sulfur, and phosphorous. Still, something else is going on here.

They drive planetary cycles of carbon, nitrogen, sulphur and phosphorus, by converting these elements into compounds that can be used by animals and plants and then returning them to the world by decomposing organic bodies. They were the first organisms to make their own food, by harnessing the sun’s energy in a process called photosynthesis. They released oxygen as a waste product, pumping out so much of the gas that they permanently changed the atmosphere of our planet. It is thanks to them that we live in an oxygenated world. Even now, the photosynthetic bacteria in the oceans produce the oxygen in half the breaths you take, and they lock away an equal amount of carbon dioxide.
