AstroVox :: Ερασιτεχνική Αστρονομία στην Ελλάδα :: www.astrovox.gr SkyTools 3 by Skyhound Not All Astronomy Software is the Same It's the Astronomy that matters Planetarium programs that display the sky are a dime a dozen these days. They can be found on every platform, including your phone. But as useful as displaying the sky on your mobile device can be, it doesn’t directly help you figure out what objects you should be observing. Traditionally amateur astronomers have picked objects from guide books, observed them at the time of year indicated, and waited until they were high enough above the horizon to observe. There are programs designed for observation planning, with spreadsheets of data and complicated graphics. It is the astronomy that separates SkyTools from planetariums and the spreadsheet planners. SkyTools is a complete observing system. To see the core of the SkyTools approach feel free to download the free trial of the Starter Edition. Below are some of the things that make SkyTools stand head and shoulders above the rest.
www.olympia.gr Welcome to the NSO | NSO Arasteo Astrophotography The Dark Side of the Nobel Prizes | Alfred Nobel For more than 100 years, the Nobel Prizes have recognized the finest in human achievements, from literature and science to the Nobel Peace Prize, which is given "to the person who shall have done the most or the best work for fraternity between nations, the abolition or reduction of standing armies and for the holding and promotion of peace congresses," according to the last will and testament of founder Alfred Nobel. But the origins of the Nobel Prizes, and the life of Alfred Nobel, tell a very different story, one tainted by the deaths of untold thousands of people. Alfred Bernhard Nobel was born in 1833 in Stockholm, Sweden. His father, Immanuel Nobel, was an inventor and engineer who struggled financially for much of his life. Forced to declare bankruptcy, Immanuel left Sweden and began working in St. Petersburg, Russia, where he impressed the czar ith one of his inventions — submerged explosive mines that could thwart a naval invasion.

Astronomy Picture of the Day The Discovery and Excavation of Qin's Terra-cotta Army It was in March 1974, when local farmers were drilling a well in search of water, that large pottery fragments were discovered 1.5 kilometers east of Emperor Qin’s Mausoleum. This finds subsequently led to the revelation of one pit of the First Emperor’s buried army 2,200 years ago. Since then continual archaeological work on excavation discovered another two pits successively. It has been revealed that three underground pits totally cover an area of 22,000 square meters, housing an estimated 8,000 life-size pottery warriors and horses. The three pits were built in similar basic construction. The three pits vary in size and shape. Pit 1: Pit 1, the largest pit, is in a rectangular shape. The terra-cotta warriors and horses are arrayed in a practical battle formation. Pit 2: Located 20 meters to the north of Pit 1 at the eastern end, Pit 2 is in "L" shape with a protruding rectangular area at the northern corner. The south area is composed of war chariots. The north area has only cavalry.

The Experience and Perception of Time What is ‘the perception of time’? The very expression ‘the perception of time’ invites objection. Insofar as time is something different from events, we do not perceive time as such, but changes or events in time. But, arguably, we do not perceive events only, but also their temporal relations. Kinds of temporal experience There are a number of what Ernst Pöppel (1978) calls ‘elementary time experiences’, or fundamental aspects of our experience of time. Duration One of the earliest, and most famous, discussions of the nature and experience of time occurs in the autobiographical Confessions of St Augustine. Augustine's answer to this riddle is that what we are measuring, when we measure the duration of an event or interval of time, is in the memory. Whatever the process in question is, it seems likely that it is intimately connected with what William Friedman (1990) calls ‘time memory’: that is, memory of when some particular event occurred.

Meade Telescopes, Celestron Telescopes and Telescope Accessories - OPT Telescopes Tiny Mechanical Insects Made of Watch Parts Chicago-based artist Justin Gershenson-Gates, aka A Mechanical Mind, creates tiny steampunk insects by carefully soldering together gears, springs, and other watch parts. The mechanical bugs, many of which Gershenson-Gates can balance on just his pinky finger, are miniature, multi-legged creatures that each take the artist several hours to complete. Like a robotic army of creepy crawlers, the metallic mites invoke a sense of mechanical technology come to life. There's something altogether exciting, intriguing, and frightening about the collection that screams "science fiction horror film." You can hear their metallic little legs feverishly clicking as though they're scurrying across a room just by looking at them. A number of Gershenson-Gates' mechanical insect sculptures are available to purchase through his Etsy shop. Justin Gershenson-Gates website via [from89]
