Energy systems

At ... is about thermoelectric power plants that seek to harvest the ocean waves by pumping cold water up through a heat exchanger

Mesolithic Stonehenge

At the site of Blick Mead near Amesbury, close to the earthwork known as Vespacian's Camp, we have a site that is revealing new information all the time. It overlooks Salisbury Plain and Stonehenge and has locked in a remarkable bit of history. David Jaques of Buckingham University has a career unfolding just from what has been preserved at Blick Mead. Charcoal from the site has been C14 dated and reveals the site has been continuously occupied over a period of three to four thousand years - by people with a Mesolithic culture (a reference to the micro blades they used).

Venus is still mysterious

At ... we have one of those schoolboy visions of Venus which is mostly hypothetical but written as reality. Venus is horrible! It sucks, we are told - but sucks what? It's as hot as an oven (actually, an awful lot hotter than an oven) and atmospheric pressure is 90 times that of the Earth. It rains sulphuric acid. It is a lethal place as far as humans are concerned - so no bus stops for spaceship tours on Venus. We won't be visiting the place in a hurry.

Vikings in the Arctic

At ... the discovery of Viking activity in northern Canada is not exactly something new. However, the latest finds have hit the archaeological headlines as it involves metallurgy - fragments of bronze and small spherules of glass that form when rock is heated to a high temperature. Basically, they have discovered a crucible for melting bronze in order to convert it into something different - tools or ornaments. It is long known the Vikings were in northern Canada to obtain furs and walrus ivory and other items of trade and bartering.

Unravelling String

At ... the String Theory hypothesis has been around for 30 years - and nobody has really been able to get to grips with it. Is it real ... or is it the product of being too clever by half?

This link provides a fascinating glimpse into all those high expectations associated with super strings and elaborate mathematical calculations. One suspects the theory will survive enthusiastically until all the excited young students of the time are living off a pension and swallowing statens.

Sizzling Sun

At ... we have this picture of the Sun

X-rays streaming off the Sun. This is the first picture of the Sun by NASAs nuclear spectroscopic telescope array (NuSTAR). It was designed to look into deep space in order to study x-rays from black holes and supernovas etc. It was launced in 2012 but only now has it been turned around to focus on the Sun.

Polar Stratospheric Clouds

    these beautiful cloud formations are visible inside the Arctic Circle, floating in the lower stratosphere at 25km high - and they are full of colours. Go to December, 2014, for lots of images of aurorae, meteors, and noctilucent clouds etc. It is thought polar stratospheric clouds are formed by sunlight shining through tiny ice particles.

Australian Aborigine stone circle

Okay, the political correct are comparing a circle of waist high stones with Stonehenge but this is Auntie - what do you expect. At ... the stone ring is also egg shaped, like many stone circles catalogued by Alexander Thom. It seems that Australian Aborigines were not as 'primitive' as the 'elite' formerly allowed (and read here the current Auntie view of the plebs). There was a story some years ago about Aborigine eel ponds constructed and designed to breed and semi domesticate them for later ritual use.

Stonehenge axe symbols

This is an old post but worth looking at again. At ... is about a laser scan of some of the sarsens that revealed a further 72 engravings, 71 of which were of axe symbols and the other one was a downturned dagger blade. Axes, it is admitted, are normally associated with storm gods. In this instance, perhaps a meteor storm as indicated by Moe Mandelkehr in his several SIS Review articles.
