The Wraparound Spider – Now You See Me…

Say what you will about Australia’s wraparound spider – it isn’t out to get you.  At least, that’s what this article tells us. Unlike (apparently) most of Australia’s animal population, this little guy (and it is little) just wants to be left alone.  In order to ensure that, it has evolved a way of wrapping its body around a twig or small branch, pressing itself down, so that it is indistinguishable from the twig, making it very difficult for its predator (the local bird population) to see it during daylight hours.  Our sibling site, the Ark in Space, has the lowdown on this fascinating spider species, as well as a fantastic picture gallery to go with it.

The Kalash – The White Tribe of Pakistan

In the mountains of the Hindu Kush in Pakistan, six thousand or so people live who look and sound very different from their neighbors.  They claim to have lived in the area for thousands of years and they look to all intents and purposes, European.

The Rolling Bridge That Curls

Something strange goes on every Friday in Paddington Basin, London.


At first sight it looks just like any other normal bridge.  Spanning the Grand Union Canal in Paddington Basin, London – the minimal design could be looked upon as somewhat plain and boring.  But once a week the Rolling Bridge as it is known does something that makes jaws drop.  Slowly at first, something remarkable happens.

Each and every Friday at midday the bridge rolls – literally.  It consists of eight sections – triangular in shape – that are hinged at ground level.  Concealed in vertical posts in the parapets of the bridge are pistons.  These pistons collapse the two part links that connect the section and the bridge can roll up.  It is the only bridge of this kind in the world and although it is known as a rolling bridge this is something of a misnomer.  By rights it should be called a curling bridge (and is by many).

Africa’s Unique Volcano: Ol Doinyo Lengai

For countless generations, the Maasai people of Tanzania have called the active volcano which dominates their landscape Ol Doinyo Lengai. The name translates as the Mountain of God.  Yet on the day Eng’ai, one of the gods of the Maasai, created this volcano she must have been in an unusual state of mind. Where most volcanoes spew lava which is rich in silicate materials, Ol Doinyo Lengai is different: very different.

Among all the active volcanoes in the world, Ol Doinyo Lengai is unique.  Its yield of lava is natrocarbonatite in nature. In other words, its mineralogical composition consists of greater than 50 percent carbonate minerals.  A carbonatite is a type of igneous rock more often enveloped in other formations and does not usually make it to the surface on its own.  It is often mistaken for marble. Although there are other examples of natrocarbonatite volcanoes in the world, all but Ol Doinyo Lengai are extinct.  If you want to see a truly different volcano, this is the one to put on the bucket list.

The Garden of Cosmic Speculation

Open to the public only one day a year, the Garden of Cosmic Speculation takes science and maths as its inspiration. Quite simply, there isn’t another garden like it in the world.

The shapes of science and nature come together in this wondrous place.  The steel curves of science stand in front of those provided so generously by nature.  Yet in a small time you can find yourself face to face with the wonders of a black hole.

The garden was set up by Charles Jencks, together with his late wife Maggie Keswick and is located at Portrack House near Dumfries. That’s in Scotland, by the way! It was set up in 1989 without the usual ideas people have when they create a garden. Horticultural displays very much take second place in this garden. Instead, it is designed with ideas in mind – and to provoke thought (or at least speculation) about the very nature of things.

The garden can be found at the base of these marvellous steps leading down from the original eighteenth century manor house with a Victorian addition, an octagonal folly-library. 

Around the garden one can find amazing sculptures on themes such as this - the DNA helix in giganitic metallic glory.

The snail mound allows visitors to explore for themselves the Fibonacci sequence of numbers that make up a shell or at least feel it beneath their feet.

However, are you interacting with it or is that the other way around?

Fractals and black holes abound, so be careful where you tread! Even thelandscaping explores the mysteries of science.

The garden comes replete with elegant manmade lakes which were designed by Maggie Keswick. The natural features of the garden blend and bond beautifully with the arches, contours, curls and bends of the science represented here. Symmetry, chaos and the tumult of nature and science combined.


Many people wish the garden was open for more than one twenty four hour period each year – but at the end of the day it is a private garden created by private individuals. All is not lost, however. It seems that recently, Mr Jencks met with Professors Peter Higgs and Rolf-Dieter Heuer. The latter is the Director General of the European Organisation for Nuclear Research. We know it as CERN, the place with that big collider thingamajig.

The two scientists hope that they may be able to replicate the Garden of Cosmic Speculation at CERN, or at least something very much like it. You can hardly blame them for wanting to reproduce something so stunning for more public viewing.

You will find all sorts of thought provoking objects to arouse your sense of wonder in this thirty acre microcosm of the universe. Many ideas come together to form a whole, complex and mystifying, cryptic but thrilling. If you find it all too much you can always spend a while in the Nonsense Pavilion (above).

Such is the way that people are enthralled by the garden it has even been immortalised in an orchestral composition by US composer Michael Gandolfi and recorded by the Atlanta Symphony Orchestra.

The garden is open this year on May 2. Get there at the crack of dawn, however if you are thinking of paying a visit. Each year the local roads come to a virtual standstill by midmorning, such is the interest generated by this wonderful place.
