physics - FQXi comm. Time and the Nature of Reality By ZEEYA MERALI We recently ran an article (courtesy of Nautilus Magazine) in which physicist Paul Davies ran through some open questions about the nature of time.

Quantum Physics Books - books about quantum physics - list of quantum physics books Quantum physics is one of the most complex concepts in modern physics and a number of books have come out in an effort to explain these quantum concepts to the general public. Here are some of them. 1. In The Quantum Universe (And Why Anything That Can Happen, Does), physicists Brian Cox and Jeff Forshaw explore the way quantum physics manifests at the most basic level to create the world of our everyday experience ... using rules that completely violate the intuitions that come from that experience. 2. Oxford University Press In this book, physics professors Bruce Rosenblum and Fred Kuttner explore the controversial role of consciousness in quantum theory. 4. Yale University Press In this book, John Polkinghorne - a physicist turned Anglican priest - discusses the thematic similarities that he perceives between the methodologies that physicists use to explore quantum physics and those applied by priests and theologians to the study of Christianity.
Doomsday rule The Doomsday rule or Doomsday algorithm is a way of calculating the day of the week of a given date. It provides a perpetual calendar since the Gregorian calendar moves in cycles of 400 years. This algorithm for mental calculation was devised by John Conway[1][2] after drawing inspiration from Lewis Carroll's work on a perpetual calendar algorithm.[3][4] It takes advantage of the fact that each year has a certain day of the week (the doomsday) upon which certain easy-to-remember dates fall; for example, 4/4, 6/6, 8/8, 10/10, 12/12, and the last day of February all occur on the same day of the week in any given year. Applying the Doomsday algorithm involves three steps: This technique applies to both the Gregorian calendar A.D. and the Julian calendar, although their doomsdays will usually be different days of the week. The algorithm is simple enough for anyone with basic arithmetic ability to do the calculations mentally. Doomsdays for some contemporary years[edit] Examples[edit] Note:
Browse Journals By RSS/Atom Feeds What are RSS and Atom feeds? RSS and Atom news feeds are computer-readable files that summarise new content as it appears on a website. (RSS and Atom are just two different formats that do basically the same thing.) Each feed includes a heading, a brief description of the new content and a link through to the website. Stay in touch with new publishing News feeds are a very convenient way of keeping up-to-date with a large number of websites. ‘ Syndicating ’ content News feeds are also an easy way for other websites to get and display content. How can I get Cambridge Journals Online feeds? You need to install a newsreader on your computer.
Physics Various examples of physical phenomena Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy.[8] Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific Revolution in the 17th century, the natural sciences emerged as unique research programs in their own right.[b] Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms of other sciences[6] while opening new avenues of research in areas such as mathematics and philosophy. Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. History Ancient astronomy Astronomy is the oldest of the natural sciences.

Montegancedo Astronomical Observatory Desde el mes de Diciembre se ha puesto en marcha el primer experimento. En este caso el público podrá observar el Sol en el horario establecido. De momento se sigue trabajando en mejorar el observatorio y conseguir un sistema totalmente fiable de modo que el observatorio pueda permanecer abierto sin la presencia de un operador. Por este motivo se ha escogido el Sol como primer objeto a observar. En el momento que el sistema sea totalmente autónomo, se podrán realizar observaciones nocturnas. Actualmente para acceder a la interfaz de control del experimento hay que realizar previamente una reserva. El objetivo de este primer experimento es poder observar el Sol en la banda H-alfa y poder distinguir las manchas y protuberancias solares, además de aprender a cambiar los diferentes parámetros de las cámaras para obtener buenas imágenes astronómicas.
