Solving the Mystery of River Formation | Science | AAAS Solving the Mystery of River Formation | Science | AAAS Look outside after a heavy rain and you may find a miniature Grand Canyon in your backyard, complete with a complex network of tributaries. The precise conditions that cause rivers of all sizes to form branches have long been a mystery; now, a new study pinpoints two opposing physical forces that work together to produce the intricate patterns. The discovery could help scientists better understand rivers at all scales and even on other worlds; for example, the icebound methane rivers on Titan, one of Saturn's moons. When rain hits a tilted surface, like the side of a mountain or a hill, it tends to flow toward existing depressions. The flow of water erodes the rock or soil, widening and deepening the depressions. Called incision, the process is competitive and even somewhat cannibalistic. Perron and colleagues guessed that a certain ratio between rates of incision and soil creep acts as a "tipping point" for the creation of river branches.

The natural sciences are the sciences that seek to elucidate the rules that govern the natural world through scientific methods, the cornerstone of which is measured by quantitative data. Based on formal sciences, they also attempt to provide mathematical (either deterministic or stochastic) models of natural processes. The term "natural science" is used to distinguish the subject from the social sciences, such as economics, psychology and sociology, which apply the scientific method to the study of human behavior and social patterns; the humanities, which use a critical or analytical approach to study the human condition; and the formal sciences such as mathematics and logic, which use an a priori, as opposed to empirical methodology to study formal systems. There are five branches of natural science: astronomy, biology, chemistry, the Earth sciences and physics.

Philosophy of science Philosophy of science is a branch of philosophy concerned with the foundations, methods, and implications of science. The central questions concern what counts as science, the reliability of scientific theories, and the purpose of science. This discipline overlaps with metaphysics, ontology and epistemology, for example, when it explores the relationship between science and truth. While the relevant history of philosophy dates back at least to Aristotle, philosophy of science emerged as a distinct discipline only in the middle of the 20th century in the wake of logical positivism, a movement that aimed to formulate criteria to ensure all philosophical statements' meaningfulness and objectively assess them. Today, some thinkers seek to ground science in axiomatic assumptions such as the uniformity of nature. Introduction[edit] Defining science[edit] Karl Popper c. 1980s Distinguishing between science and non-science is referred to as the demarcation problem.

Neuroscience's New Consciousness Theory Is Spiritual | Bobby Azarian Neuroscience's New Consciousness Theory Is Spiritual | Bobby Azarian “Science is not only compatible with spirituality; it is a profound source of spirituality” -Carl Sagan It appears that we are approaching a unique time in the history of man and science where empirical measures and deductive reasoning can actually inform us spiritually. Integrated Information Theory (IIT)—put forth by neuroscientists Giulio Tononi and Christof Koch—is a new framework that describes a way to experimentally measure the extent to which a system is conscious. As such, it has the potential to answer questions that once seemed impossible, like “which is more conscious, a bat or a beetle?” The decline and demise of the mystical As more of the natural world is described objectively and empirically, belief in the existence of anything that defies current scientific explanation is fading at a faster rate than ever before. This is because modern science has achieved impeccable performance when it comes to explaining phenomena previously thought to be unexplainable. That’s right.

science « Nonfiction Comics The explanation of how DNA works can be as complicated as the organisms it helps put together. And yet, because this knowledge is essential to understanding the entire field of biology, we expect students to learn all about this alphabet soup, from ATGC to XX and XY. In The Stuff of Life: A Graphic Guide to Genetics and DNA, writer Mark Schultz and artists Zander and Kevin Cannon attempt to construct a comprehensive primer that not only explains each component and how each process works, but to make sure they come together into a complete picture, better to ensure a true understanding of the subjects rather than a disconnected series of facts. The reader basically stands at the side of Floorish 727 as Bloort lays it all out, starting with the most complicated concepts first—how the molecules all come together—and eventually working his way up to the cellular level, trait inheritance, and finally practical applications of this increased genetic knowledge. science « Nonfiction Comics

Food Science

Food technologist: Job description Food technologists make sure food products are produced safely, legally and are of the quality claimed. They can be involved in developing the manufacturing processes and recipes of food and drink products and may work on existing and newly discovered ingredients to invent new recipes and concepts. Technologists modify foods to create products such as fat-free items and ready meals. They often work closely with the product development teams to help deliver factory ready recipes based on the development kitchen samples. Some food technologists are involved in conducting experiments and producing sample products, as well as designing the processes and machinery for making products with a consistent flavour, colour and texture in large quantities. The work may involve building relationships with suppliers and customers, as well as ensuring products are profitable. Typical work activities In food manufacturing, the work may also involve: In retailing, additional tasks include:

Hands-On Optics (HOO) Making an Impact with LightHands-On Optics (HOO) was a four-year informal science education program funded by a $1.7 million grant from the National Science Foundation (NSF). The project was collaboration between SPIE, the Optical Society of America (OSA) and the National Optical Astronomy Observatory(NOAO). The program brought science education enrichment to thousands of underrepresented middle school students in more than ten states, including female and minority students, who typically have not been the beneficiaries of science and engineering resources and investments. HOO provided more than 100 teachers with up to six activity modules, each containing enough materials for up to 30 students to participate in 6-8 hours of hands-on optics-related activities.
