Nicola Tesla

Nicola Tesla is one of those people very often sidelined in life but almost worshipped after his death. There is a review of him at www.livescience.com/45980-nicola-tesla-biography.html ... and it seems Tesla most famously invented AC - in opposition to Edison's DC. Tesla's AC was eventually adopted in spite of all the money and influence that Edison was able to throw at his preferred system. AC was simply more reliable.

The Little Ice Age and the Sun

At http://phys.org/print323856790.html ... there is a report on study that derives from an ice core section. It was analysed for various chemical traces in a laboratory (several cores from different locations on Antarctica) and the results are said to be an accurate and precise recontruction of historic volcanic sulphate emissions - in the southern hemisphere.

Human evolution

At http://phys.org/print323596759.html ... scientists have revised the timeline of human origins after it was found Homo erectus sometimes overlapped their assumed ancestors by several hundred thousand years. This sounds an awfully long time but it is worked out from dating geological deposits and therefore may be subject to some revision itself in the future. Be that as it may it would seem to cast doubt on the evolution from one to the other - but that is not the outcome.

Sea Henge mark 2

It seems there were two timber henges discovered at Holme on the Norfolk coast. The New Age druid demonstrators made a lot of fuss about the removal of the first one (now preserved in a museum setting) and yet there was another one out there all the time, in its watery grave. Inroads by the sea are hastening its disappearance - and the kind of ending that would have occurred if the first henge had not been saved (as the demonstrators wished).

co2 magic dust

At http://archaeologynewsnetwork.blogspot.co.uk/2014/07/c02-burp-helped-tri... ... we are told a team of scientists have discovered some CAGW fairy dust - a giant burp of co2 from the North Pacific Ocean that triggered the end of the last Ice Age, 17000 years  ago. According to the theory, as that is what it is, a change in ocean circulation helped trigger the co2 burp. No explanation is offered as to why the ocean circulation changed - although of course there are plenty of theories for this out there as well.

Noctilucent in the News

At http://spaceweather.com of July 4th 2014 (you will have to scroll down) we have a nice image of noctilucent clouds and a short explanation. They have been particularly common across Europe in recent days, beginning on July 3rd. The northern horizon was filled with electric blue ripples, coils, and tentrils of light. These clouds are said to be caused by meteor smoke, forming at the edge of space 83km above the surface of the Earth, where sun light strikes the small icy crystals left behind by nature.

Blick Mead update

Blick Mead, overlooking the river Avon, is also the feature of an article in Current Archaeology 293 (see once again, www.archaeology.co.uk - but remember the articles in the current issue are not uploaded to the web site for several weeks afterwards, otherwise people would not buy the magazine). The Mesolithic period remains (prior to 6000BC) were found beneath what became an Iron Age hillfort - Vespasian's Camp (a bit of antiquarian speculation as it long pre-dates the Roman general and emperor of that name).

What was Silbury Hill built to imitate?

An article in Current Archaeology 293 (July/August 2014) (see also www.archaeology.co.uk) makes the point that Silbury Hill sits at the head of the Kennet River - which joins the Thames at Reading. Although modern maps have the head of the Thames near Lechlade, but might this be regarded as one of several tributaries. It asks, perhaps Neolithic people saw the Kennet as more properly a continuation of the Thames, rather than the long loop that goes by way of Oxford. They go further and say, Silbury Hill was positioned in a special landscape.

What was happening in the years leading up to 1300AD?

At http://archaeologynewsnetwork.blogspot.co.uk/2014/07/ancient-baby-boom-h... ... the lesson the co-authors have in mind is that over population is supposed to be a problem and the modern world is seriously over populated - in their opinion. They go further as they claim they have found an ancient record of over population that ended in tragedy after a bout of drought - but they are lean on the extent and magnitude of the drought or the possibility of migration by those affected by drought.

Irish mythology

Patrick McCafferty was a speaker at an SIS autumn meeting a few years ago - and came across as somebody to watch. It seems he has teamed up with Dallas Abbot over in the States and they have made a programme for the Smithsonian Channel, a documentary concerning the mysterious history of Ireland in the 6th century AD - go to http://cosmictusk.com/irish_history_myth_comet_asteroid_mccaffferty/
