"o , where you can record what you see in nature, meet other nature lovers, and learn about the natural world. "

"how engineers can use biomimicry to enhance their designs. They learn how careful observation of nature - in this case, reverse engineering a flower to glean design ideas - can lead to new innovations and products. "

loons on Mason Lake and a chorus of birds in Queensland, Australia, thanks to this Mashable link to the free natural sounds archive, now available online from the Macaulay Library at the Cornell Lab of Ornithology. As Open Culture reports, the recordings go back to 1929.

"20th-century mathematical genius Amalie Noether. Emmy Noether's theorem united two pillars of physics: symmetry in nature and the universal laws of conservation. Albert Einstein called her the most "significant" and "creative" female mathematician of all time, and others of her contemporaries were inclined to drop the modification by sex. She invented a theorem that united with magisterial concision two conceptual pillars of physics: symmetry in nature and the universal laws of conservation"

"The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

"Louie Schwartzberg is an award-winning cinematographer, director, and producer whose notable career spans more than three decades providing breathtaking imagery for feature films, television shows, documentaries and commercials. As a visual artist, Louie has created some of the most iconic and memorable film moments of our time. He is an innovator in the world of time-lapse, nature, aerial and "slice-of-life" photography - the only cinematographer in the world who has literally been shooting 24 hours a day, 7 days a week continuously for more than 30 years. "

"Engineering: An Introduction for High School is an open-source high school "flexbook" created using software developed by the CK-12 Foundation by engineering and education faculty at Arizona State University. The flexbook format allows the book to be customized for multiple audiences. The text can be updated, expanded, and repurposed as necessary to support specific standards and classroom needs. The current draft has four content chapters that cover the nature of engineering, engineering and society, engineering design, and the connection between engineering, science, and mathematics."

"Turn your students into citizen scientists in three simple steps! Project Noah was created to provide people of all ages with a simple, easy-to-use way to share their experiences with wildlife. By encouraging your students to share their observations and contribute to Project Noah missions, you not only help students to reconnect with nature, you provide them with real opportunities to make a difference."

"For Civil Engineers, the alchemy of earth, rock, steel and concrete formed by man to hold back and harness that most powerful force of nature, water; is an awesome sight to behold, worthy of photographing, inspiring the young and old to imagine the weight of the wall of water behind the stark grey walls, wondering at the cold, murky depths below the calm surface. On a quiet day, the dam can seem tame. The moving parts are hidden away, only a faint hum or vibration may be evidence of the great transformation from potential to kinetic to electric energy taking place below your feet. Looking downstream, the flow of the river continues, thousands of cubic meters of water"

"fascinating devices that don't work. It houses diverse examples of the perverse genius of inventors who refused to let their thinking be intimidated by the laws of nature, remaining optimistic in the face of repeated failures. Watch and be amazed as we bring to life eccentric and even intricate perpetual motion machines that have remained steadfastly unmoving since their inception."

"All magnetic fields are produced by moving or spinning charged particles…somewhere Magnetism is a force in nature that is produced by electric fields in motion. This movement can involve electrons 'spinning' around atomic nuclei, flowing through a conducting wire, or ions moving through space in an organized stream. The remarkable thing is that whenever a charged particle moves, the electric field it produces is also moving through space, and it is this moving electric field that is detected as a magnetic field. "

"Environmental engineering is the integration of science and engineering principles to improve the natural environment (air, water, and/or land resources), to provide healthy water, air, and land for human habitation (house or home) and for other organisms, and to remediate pollution sites. Further more it is concerned with finding plausible solutions in the field of public health, such arthropod-borne diseases, implementing law which promote adequate sanitation in urban, rural and recreational areas. It involves waste water management and air pollution control, recycling, waste disposal, radiation protection, industrial hygiene, environmental sustainability, and public health issues as well as a knowledge of environmental engineering law. It also includes studies on the environmental impact of proposed construction projects."

"G.F.C Rogers, in his book "The Nature of Engineering" (1983) defines engineering as "the practice of organising the design and construction of any artifice which transforms the physical world around us to meet some recognised need.""

"Engineering offers more career options than any other discipline. It's a profession that can take you from the depths of the ocean to the far reaches of outer space, from within the microscopic structures of the human cell to the top of the tallest skyscrapers. Whether it's cell phones, digital cameras, DVD's, or facial recognition devices that can pick out a terrorist in a crowded football stadium, engineers are behind almost all of today's exciting technology. Engineers are problem solvers who search for quicker, better, and less expensive ways to use the forces and materials of nature to meet today's challenges. Engineering students have their pick of many fields. From electrical to civil to aeronautical to biomedical, every discipline within engineering will lead to an exciting and rewarding career. In this activity, you will research one type of engineering"

""Discovering Careers in the Earth Sciences" Take part in Earth Science Week 2012! Held October 14-20, ESW 2012 encourages people everywhere to explore the natural world and learn about the geosciences. "Discovering Careers in the Earth Sciences," the theme of ESW 2012, engages young people and the public in learning how geoscientists gather and interpret data about the Earth and other planets."

"Understanding the engineering process means understanding the way things work and how technology helps advance society. Leading children through engineering discoveries is to lead children through natural curiosity and learning experiences. "

"Whether they are created by nature or in the lab, chemical substances are all made of some combination of just 118 pure elements. These elements come together to produce an amazing diversity of materials. In this interactive, discover which elements are most abundant in the universe, the sun, and the Earth as well as in the human body and in that flashiest of human creations-fireworks. "
