Thoughts. They fly through the broad expenses of our mind, floating gracefully in midair, going into the clouds, and then reemerging once again. Some are quick and furtive, others are grand and majestic. We reflect upon them as they enter our minds, and once they leave, they are usually gone for good. However, some thoughts are different. These thoughts resemble a flock of angry birds or a swarm of hungry moths that invade your mind, slowly eating away at your sanity, strength, and desire to live. Such thoughts often plague that minds of people with Obsessive Compulsive disorder. They completely occupy their time; constantly there; ever-present. With his book sculpture, Thomas Wightman was able to accurately convey the way these thoughts consume the mind, slowly building a nest within it, resisting all attempts to drive them away.

A British photographer has captured life at the “edge of the world”. Timothy Allen, best known for his work on BBC's Human Planet, trekked through the freezing Siberian wilderness for 16 days as he joined part of an 800km migration of reindeer in the Yamal-Nenets region – a name that roughly translates to “edge of the world”. The stunning pictures feature the nomadic Nenets tribe, who drink blood to survive in -45°C temperatures. Timothy's epic journey, which will be revealed in an eight-minute documentary on Animal Planet USA, saw him travel across the bleak terrain of the frozen Ob River with the Nenets people in December last year.

Everyone wants to get something for nothing - whether it's a lucky upgrade that means you can turn left when you get on a plane instead or heading off into the economy seats, or even getting a few extra features thrown in for free when you buy a new car.

As some of the sharpest businesses around, no-one understands this quite as well as casinos and that's why they all have a system that they call comps. It's short for "complimentary offers" and these are special treats specially designed to reward you for your loyalty to the casino in question. They're basically bonuses.

67-year-old Guinness Rishi constantly tries to make his family and the entire Indian people by constantly setting new records.

Do you think that history is a science? Well, not exactly. First, and foremost, history is the state's “legend of wars”, it’s official regalia. Of course, public historians are not interested in scientific truth – quite the opposite. In this respect, any attempt to present a state’s history as altruistic and benevolent as possible is welcomed and encouraged – as opposed to any revisionism attempts that may be more accurate. In this matter, Chinese have surpassed us all – they revised in highly creative manner (but rather shamelessly) the technology already invented by Europeans, a process that resulted in oldest state on the planet. Here is an interesting paradox: ask any sinologist about the Middle Kingdom during second century B.C., and he will describe it to you in such a vivid manner as if he has been living there all his life – but as soon as you will ask him to describe Chinese history in the 19-20th centuries… let's say, his eagerness will be greatly diminished. However, we will discuss China in a different article, and in the meantime we will try to understand how exactly historic “legend of wars” is formed and functions – based on a specific and well-known example. A great example is Ferdinand Magellan's first voyage around the world.
