Turn Every Walk into a Game of Detection

When writer and navigator Tristan Gooley journeys outside, he sees a natural world filled with clues. The roots of a tree indicate the sun's direction; the Big Dipper tells the time; a passing butterfly hints at the weather; a sand dune reveals prevailing wind; the scent of cinnamon suggests altitude; a budding flower points south. To help you understand nature as he does, Gooley shares more than 850 tips for forecasting, tracking, and more, gathered from decades spent walking the landscape around his home and around the world.

A Powerful Window into Cosmic Evolution

Terahertz (THz) observations of interstellar atoms, molecules, and dust serve as powerful probes of the conditions within the interstellar medium that permeates our galaxy, providing insights into the origins of stars, planets, galaxies, and the Universe. Taking a cross-disciplinary approach to the subject, Terahertz Astronomy explores THz astrophysics and the technologies that make this rapidly evolving field possible.

The first four chapters of the book discuss the origin and interpretation of...

Since the use of high-precision/resolution spectroscopy is closely connected to the ability to collect a large number of photons, the scientific domains using this technique benefit tremendously from the use of 8-meter class telescopes and will fully exploit the tremendous gain provided by future Extremely Large Telescopes (ELTs). This volume comprehensively covers the astrophysical and technical aspects of high-precision spectroscopy with an outlook to future developments.

During the last two decades, remarkable and often spectacular progress has been made in the methodological and instrumental aspects of x-ray absorption and emission spectroscopy. This progress includes considerable technological improvements in the design and production of detectors especially with the development and expansion of large-scale synchrotron reactors All this has resulted in improved analytical performance and new applications, as well as in the perspective of a dramatic enhancement in the potential of x-ray based analysis techniques for the near future. This comprehensive...

Four hundred years ago, on 25 September 1608, the lens maker Hans Lipperhey from Middelburg in the Netherlands traveled to The Hague to apply for a patent regarding his invention of the "spyglass." The Commander in Chief of the Dutch armed forces, Prince Maurice of Nassau, was quite impressed. However, since the instrument could be easily copied, Lipperhey was not granted the patent. Nevertheless, within a year Galileo Galilei aimed a telescope that he had built based on the principals of Lipperhey's device on the skies, forever changing the way astronomy was done.

This captivating collection of astrophotography records the otherworldly beauty of Yosemite at night. The Milky Way stretches above world-famous features that appear utterly transformed after dark. Yosemite Valley glows beneath moonlit cliffs. Star trails stripe the sky over a snow-capped Half Dome. A brilliant blue and pink storm electrifies the vista from Olmsted Point. Rock climbers' headlamps glimmer like fireflies on mighty El Capitan....

Advances in Machine Learning and Data Mining for Astronomy documents numerous successful collaborations among computer scientists, statisticians, and astronomers who illustrate the application of state-of-the-art machine learning and data mining techniques in astronomy. Due to the massive amount and complexity of data in most scientific disciplines, the material discussed in this text transcends traditional boundaries between various areas in the sciences and computer science.

The book s introductory part provides context to issues in the astronomical...
