Nostalgia For The Light (12A)

Directed by Patricio Guzman

Thursday 12 July 2012

Awesome. Nostalgia For the Light should be required viewing for misanthropists everywhere, especially those who supported Pinochet’s regime in Chile.

Opening with the wheels of a telescope being positioned and images of the pockmarked moon, film-maker Patricio Guzman narrates his fascination for studying the stars.

It’s nothing to do with astrology but about looking for the origins of the universal material forces that created our species, since we live by the light of long dead stars.

Then the camera looks back to Earth to see Chile’s Atacama desert, a place without humidity and no natural animal life

not completely true. See here.

except astronomers and archeologists.

The first study stars and meteorites and the second search for fossils and neolithic art, reminding us that the native Amerindians have become the “unmentionables.”

Many died as slaves building the 19th-century railways, their work huts providing Pinochet in the 1970s with an ideal site for concentration camps that disposed of those called the “disappeared.”

People search for traces of their loved ones so they can rest the ghosts in their mind while reminding the so-called civilised world that they collaborated with massacring millions.

An architect shows how he paced out the measurements of the camps, then drew them on paper which he destroyed and then redrew them again from memory while living in Denmark.

The history is still raw. Every day the survivors walk the same streets as the unpunished perpetrators, providing a testimony of a time that too many would like to keep us in the dark about.

Every scrap of evidence is bagged and tagged, while others recall the tremendous courage and ingenuity employed by the living to become “transmitters of history.”

Guzman stresses the value of memory. “Those who have a memory are able to live in the fragile present moments. Those who have none don’t live anywhere,” he states.

A damning indictment of systematic genocide, the film illustrates that humanity has the resilience and imagination to learn from the past to make a better future.

It’s the common cause.

Dinosaur eggs discovery and bird evolution

Fossil Egg Discovered in Lleida (Spain) Links Dinosaurs to Modern Birds

12 July 2012

Researchers from the Complutense University of Madrid and the Universitat Autònoma de Barcelona identified in Lleida a series of dinosaur eggs with a unique characteristic: they are oval in shape. The discovery represents proof in favour of the hypothesis that birds and non avian theropods, dinosaurs from the Cretaceous Period, could have a common ancestor.

Before her death in December 2010, Nieves López Martínez, palaeontologist of the Complutense University of Madrid, was working on the research of dinosaur eggs with a very peculiar characteristic: an ovoid, asymmetrical shape. Together with Enric Vicens, palaeontologist of the Universitat Autònoma de Barcelona, the two scientists conducted an exhaustive analysis of their discovery, recently published in the journal Palaeontology.

The new type of dinosaur egg has been given the scientific name of Sankofa pyrenaica. The eggs were discovered in the Montsec area of Lleida, in two sites located on either side of the Terradets pass.

The South Pyrenean area is rich in dinosaur egg sites, most of which correspond to sauropod eggs from the upper Cretaceous, dating back more than 70 million years ago. During that period, the area was a coastal area full of beaches and deltas which won land from the sea through sediment accumulation. Sand and mud from that period gave way, millions of years later, to the sandstone and marl where dinosaur remains now can be found. On the beach ridges and flat coastal lands is where a large group of dinosaurs laid their eggs.

The sites where the discoveries were made correspond to the upper Cretaceous, between the Campanian and Maastrichtian periods, some 70 to 83 million years ago. The fossils found belong to small eggs measuring some 7 centimetres tall and 4 cm wide, while the eggshell was on average 0.27mm thick. Most of the eggs found were broken in small fragments, but scientists also discovered more or less complete eggs, which can be easily studied in sections. The eggs found at the sites all belong to the same species. The main difference when compared to other eggs from the same period is their asymmetrical shape, similar to that of chicken eggs. The more complete samples clearly show an oval form rarely seen in eggs from the upper Cretaceous period and similar to modern day eggs.

Their shape is a unique characteristic of theropod eggs from the upper Cretaceous period and suggests a connection with bird eggs. Non avian dinosaur eggs are symmetrical and elongated. Asymmetry in bird eggs is associated to the physiology of birds: they take on this shape given the existence of only one oviduct which can form only one egg at a time. In this case the isthmus, the region in the oviduct creating the eggshell membrane, is what gives the egg its asymmetrical shape. Thanks to this shape, the wider end contains a bag of air which allows the bird to breathe in the last stages of its development. This evolutionary step was still relatively underdeveloped in dinosaurs.

Thus, the egg discovered by UCM and UAB researchers in certain manners represents the missing link between dinosaurs and birds. Only one other egg, discovered in Argentina and corresponding to a primitive bird from the same period, has similar characteristics. The discover represents proof in favour of the hypothesis that non avian theropods, the dinosaurs of the Cretaceous period, and birds could have had a common ancestor.

Virginia plantation video


The makers of this video from the USA write about it:

This is Belle Grove Plantation in Virginia. We are working to open this plantation as a Historic Bed and Breakfast. As you will hear in the video, this plantation has some very important history attached to it. It is the birthplace of James Madison and was part of the trail that John Wilkes Booth and David Harold crossed as they made their way across the river and on to Garrett’s Farm. It was also the plantation that the Detachment of Union soldiers that were pursuing them stopped to rest and eat.

They also write about it:

See what it looks like as you drive up to the Manor today. Watch for our resident osprey to fly over the house as you approach the front door. See the grounds as they are today, before we start the landscaping. Get a close look at the Summer Kitchen, Ice House and Smokehouse.
