The world of physical phenomena can be investigated by science. Science has developed over the last two hundred years to put forward hypotheses, challenge them test them and develop theories about how the physical world behaves according to rules. In general this system works because we can make predictions about how physical things will behave and this has allowed the rapid development of technology so we know it works. Many people believe in a supernatural world. This world has been put forward in various forms to explain, the origin of all things, human free will and so on. If the supernatural world interacts with the physical world at some point the supernatural world actually has to manifest a physical effect. It has to, for example, start an electrical impulse that causes motor neurones to fire and our bodies to move. In the case of god he has to be able to create matter and energy that wasn't there before to move things about. God is a bit difficult to test because he doesn't always show up but the human soul must constantly be interacting with the physical world. It must be receiving information from the physical world, which means that physical energy must be disappearing into the supernatural world. This makes it a physical phenomenon that we just don't understand at the moment. Presumably believers think that if we manage to map all the physiological functions of the human brain we would be left with a gap – effectively a machine without a controller, a robot with no commands. Assuming this soul exists why can't we detect it? If we can some day detect it what is it made of? If it exists how does it work? How is my soul different from yours? How does it process physical information? Presumably the supernatural world is a world that co-exists with ours but only interacts along a certain interface. Are there rules for this interaction? What is the limit of the power of the soul? To me suggesting the existence of a soul as though it answers any questions is a very strange thing it just raises more questions. It just forces the question of consciousness out of the physical world and then I'm forced to ask well how does the soul's consciousness work?

A strange weakness in the Earth's protective magnetic field is growing and possibly splitting, shows data.
- "The South Atlantic Anomaly" in the Earth's magnetic field is growing and possibly splitting, shows data.
- The information was gathered by the ESA's Swarm Constellation mission satellites.
- The changes may indicate the coming reversal of the North and South Poles.

Researchers detect a large lake and several ponds deep under the ice of the Martian South Pole.
- Italian scientists release findings of a large underground lake and three ponds below the South Pole of Mars.
- The lake might contain water, with salt preventing them from freezing.
- The presence of water may indicate the existence of microbial and other life forms on the planet.

"Nothing but naked people: fat ones, thin ones, old, young…"
"The Yellow Sands", 1888, John Reinhard Weguelin; source: Wikimedia Commons<h3>Naked revolution</h3><p>Yet long before anyone knew about beach fashion, naturism was trendy. Bathing naked in the sea was going on in England as early as 1840. However, during the reign of Queen Victoria, this pleasure was outlawed. But it popped up again among the conservative Germans. In 1898, the first Naturist Club was founded in Essen and in 1900 the Wandering Birds group (<em>Wandervögel</em>) was scouring the country for uninhabited places and naked sunbathing. In the same year, Heinrich Pudor wrote <em>The C</em><em>ult of </em><em>the </em><em>Nud</em><em>e</em>, winning the hearts of contemporary supporters of naturism.</p><p>In the 1920s, on the back of this, members of the Movement for Natural Healing (<em>Naturheilbewegung</em>) organized naked sunbathing for the improvement of health. Persuaded by Pudor's theory of the healing properties of the sun and wind, which could be absorbed through the skin, they launched the naked revolution.</p><p>Pudor's book became the naturists' manifesto and soon after, not far from Hamburg, the Free Body Culture (<em>Freikörperkultur</em>, or FKK) movement was founded. This spread through other German centres and brought together thousands of people. The FKK still operates under the same name today.</p><p>The cult of the naked body even wrote itself into the ideology of fascist Germany, which advocated a pure, Aryan race. But in 1933, Hermann Göring issued an order that defined nudity as "the greatest threat to the German soul" and, with that, criminalized naturist organizations. But this wasn't the end of the movement. The naturists went underground, continuing their activities under the guise of improving physical fitness.</p><p>In 1936, the idea was even floated of having a naturist display to open the Berlin Olympic Games. It was quickly dropped. Despite this, in 1939 the naturists managed to organize their own Games in the Swiss village of Thielle.</p>
