Title: Aperture Arrays - Past, Present & Future
Abstract: I will present a brief history of the contribution dipole (aperture) arrays have made to radio astronomy - from Jansky's merry-go-round to LOFAR, from the Jocelyn Bell's 4 acre array, to APERTIF and ASKAP. I will briefly consider how aperture array technology is being used in other fields with specific reference to radio astronomy's strong synergy with developments in radar systems. Looking towards the future and the SKA, I will argue that we must build a telescope that is really bold and inspirational, not incremental or more of the same, only larger. Like the makers of the Antikythera device, let's amaze future generations with our ambition and vision, with our courage to build something that no man has built before!

Title: The Antikythera Mechanism: From the bottom of the sea to the scrutiny of modern technology
Abstract: The Antikythera Mechanism was found by chance, in a shipwreck, close to the small Greek island of Antikythera, in April 1900, by sponge divers. The shipwreck was dated between 86 and 67 B.C. (coins from Pergamon). Later the Mechanism was stylistically dated, around the second half of the 2nd century B.C. (100 – 150 B.C.). About this time the great Greek astronomer Hipparchos (190 – 120 B.C.) lived in Rhodes. It was a portable (laptop-size), geared mechanism which calculated and displayed, with high precision, the movement of the Sun and the Moon on the sky and the phase of the Moon for a given epoch. It could also calculate the dates of the four-year cycle of the Olympic Games. It had one dial on the front and two on the back. Its 30, precisely cut, gears were driven by a manifold, with which the user could select, with the help of a pointer, any particular epoch (at the front dial). While doing so, several pointers were synchronously driven by the gears, to show the above mentioned celestial phenomena on several accurately marked annuli. It contained an extensive user’s manual. The exact function of the gears has finally been decoded and a large portion of the manual (~3000 letters) has been read after 2000 years by a major new investigation, using state of the art equipment. Based on new surface photography and high resolution tomography data, a new model has been built at the Aristotle University, revealing the technological abilities of ancient greeks. No complicated geared instruments are known before the Antikythera Mechanism and for several centuries after. Therefore, this astronomical device stands out as an extraordinary proof of high tech in ancient times.

Title: From Mechanical to Optical: Beamforming in Radio Astronomy
Abstract: Throughout the ages, various implementations of beamforming mechanisms for radio arrays have been implemented, ranging from kerosene beamformers to optical beamformers. In this talk, I will give a review of beamforming techniques over the ages and describe new beamforming architectures scalable to the Square Kilometre Array and beyond.

Title: Geodesy through Astronomy: Eratosthenes to the IVS
Abstract: Astronomical observations have been the key to precise measurement of the planet Earth, from Eratosthenes first measurement of the radius, to the modern International Very Long Baseline Service for Geodesy (IVS). With the IVS, radio astronomers use the technique of interferometry to help determine the precise orientation and speed of the Earth's rotation. This allows calibration of navigational satellite systems to precision of a few centimeters. Geodesy and astronomy have a long and colorful history of mutual support.

Title: Plato – from Greek philosopher to Antarctic observatory
Abstract: Plato’s (429–347 B.C.E.) views on experimental science (including astronomy) are often characterised as placing more emphasis on ideas and “modelling” than on experiment or observation, which provide only an imperfect, corrupted image of the underlying mathematical perfection. Thus, solar system bodies must follow perfect circles – an idea that became firmly entrenched and led some two centuries after Plato's death to the construction of the Antikythera mechanism. It is therefore with some irony that any observatory would be named PLATO – especially one that goes to great lengths to measure properties of the Antarctic sky that might otherwise be successfully calculated. This highlights an important question for all astronomical site testing – what really needs to be measured, and what can we simply “know” from existing models? This talk will review the knowns and unknowns of site testing, with particular reference to unexplored areas of the remote Antarctic plateau.

Title: A Clock for the Square Kilometre Array
Abstract: The Antikythera device is mechanical calendar with a level of technological complexity and precision unprecedented in its time. Similarly, the Square Kilometre Array telescope will be the largest and most complex astronomical instrument to date, with individual telescopes spread across continental scales. One of the most complex technical challenges of such an extended array is the coherent combination of astronomical signals collected independently by its many remote telescopes. Astronomical observations are therefore required to be time-stamped with clock signals of exquisite accuracy and precision. Traditionally, these signals were provided by separate atomic clocks installed at each telescope site. However, the scale of the SKA makes the cost of operating and maintaining such an ensemble of complex and expensive atomic clocks extremely difficult. Our consortium of researchers is developing a novel solution which turns the problem on its head. We plan to recycle the optical fibre network, used to transport the astronomical data to the Square Kilometre Array’s central processing node, to also distribute high-quality time and frequency signals to each telescope. To compensate for thermal, acoustic, and mechanical fluctuations of the optical fibre, we are developing active stabilisation schemes which work across continental scales. Just as the Antikythera mechanism in its day, our work brings together cutting edge technological innovations with astronomical science of the highest precision.

Title: The Antikythera Mechanism: a census of planetary extensions.
Abstract: The Antikythera Mechanism is one of the most extraordinary examples of Greek technological development and expertise known from Antiquity. This amazing piece of geared technology could best be described as a complex mechanical computer from the second century B.C., which tracks and predicts various cycles for – and related to – the Sun and the Moon. One of the many intriguing questions surrounding the mechanism is whether the movements of the planets were also described by the device. Various indications have been found supporting the existence of some sort of planetary representation. However, no actual evidence of this has been found in the surviving fragments of the Antikythera Mechanism. In this contribution, I will discuss our analysis and statistical study of possible planetary extensions (see Bos, Van de Weygaert & Pel, 2012). We argue for a gear work design to represent the locations of the planets along the Zodiac and we present a framework of boundary conditions to restrict the number of gear train reconstructions. By using 3D CAD-modeling software we are able to make reconstructions of the Antikythera Mechanism including a planetary extension.

Title: SHEVE\'82 and the Coming of Age of Southern Hemisphere VLBI
Abstract: 1982 saw the setting up of the first Southern HEmisphere VLBI Experiment (SHEVE) VLBI array. This was the first in a series of southern hemisphere VLBI astronomy, astrometry and geodesy observations which continues today. It was also Tasso\'s introduction to VLBI in his 30th year and thus predates these Workshops, which celebrate Tasso\'s 50th, 55th and now 60th year. Authors: David Jauncey and Robert Preston
