The Antikythera Mechanism – The 2000 year old computer

Often when we study ancient cultures we automatically assume that we are way ahead of them, and that they were not much advanced. We treat them as “barbarians” without an evidence for it. However, sometimes an artifact is found proving quite the opposite. This article is about one of those artifacts, called the Antikythera Mechanism.

For many decades, scientific investigation failed to yield much data and relied more on imagination than the facts. However, research over the last half century has begun to reveal its secrets. The single most information-rich machine, dated as around the end of the 2nd century B.C., is the most sophisticated mechanism known in the ancient world. Nothing as complex is known for the next thousand years. The shoe-box size bronze mechanism had its inscriptions barely readable, and its 30 bronze gears bearing thousands of interlocking tiny teeth were calcified when it was uncovered from the shipwreck at Antikythera, Greece, in 1901. The underwater excavation revealed beautiful bronze sculptures, ropes of decadent jewelry and a treasure trove of antique coins.

The reconstruction of the Antikythera Machine

X-Ray analysis of  the Antikythera Machine made by ancient Greek scientists and increasingly looking like the “philosopher’s guide to the galaxy,” as the Associated Press described it, revealed a text of a long explanatory “label” which helped us to understand it was dedicated to an astronomical phenomena and operated as a complex mechanical “computer” which tracked the cycles of the Solar System. It had dials that counted the days according to at least three different calendars, and another that could be used to calculate the timing of the Olympics. In addition to two rectangular plates that could be called front and back dials, there was an inscription which showed annually repeating astronomical events relating to the Sun and to fixed stars. While lunar eclipse related text probably ran down one side of the plate, and that for solar eclipse prediction down the other.

The front dial was surrounded by two scales, one representing the zodiac, the other the Egyptian calendar year. Pointers representing the stars and planets revolved around its front face, indicating their position in relation to Earth. The back plate has two large spiral dials. A tiny, painted model of the moon rotated on a spindly axis, flashing black and white to mimic the real moon’s movements. On this face, the upper five-turn Metonic Dial which included ‘Games’ dial represented a 235-lunar-month calendrical cycle while the lower four-turn Saros Dial including Exeligmos Dial represented a 223-lunar-month eclipse prediction cycle. It was planned as a 76-year “Kallippic” calendrical cycle.  The Games dial alone shows six Olympic competitions. The machine clearly showed the motion of planetary systems, possibly including Venus and Saturn as well.

Before the discovery of the device, researchers thought such technology had not existed for 1,000 years after.

All known fragments of the Antikythera Mechanism are currently held for research at the National Archaeological Museum in Athens.

Microsoft Engineer installs Google Chrome when Microsoft Edge crashes during presentation – Hilarious!

Microsoft presenter Michael Leworthy was doing a presentation showing the new features of Microsoft Azure. While doing his presentation suddenly the web browser Microsoft has been presenting as the best browser in the world, Edge, crashed. Leworthy was forced to install Google Chrome to finish his presentation.

While people in the audience were giggling, the Microsoft engineer tries to continue presenting like nothing happened. It shows, however, how Microsoft (and other companies) have been struggling to keep up with Google. Chrome is the most popular web browser in the world, leaving the competition far behind.

Michael Leworthy was man enough to upload the presentation himself, showing Microsoft does have some sense of humour. Then again, the presentation does not say anything negative about Azure. So if the video goes viral, they might still get some sales from it.

Watch the full presentation below below. The funny stuff happens at around 37 minutes:

Microsoft, once known as the most powerful tech company in the world, has been struggling to regain its focus. Their operating systems are still the most widely used, but they seem to be having some issues with their other products.

Bad business moves, like replacing Windows Live Messenger with Skype, or continuing to change the name of the most popular e-mail service in the world, Hotmail, did not do them any good either. Especially because they did this during the rise of Gmail, causing Google to take the take their territory on the market at an amazing speed.

We honestly hope that some day Microsoft will become the giant that it once was, again. And if not, then at least we got some funny videos like the one above. That is worth something as well.
