  The human race is at a crossroads. In the coming years, we will make decisions regarding our human spaceflight program that will lead to one of two familiar futures: the open universe of Star Trek, where we allow ourselves the opportunity to spread our wings and attempt to flourish as an interplanetary species-or the closed, dystopian, and ultimately self-destructive world of Soylent Green. If we ever hope to live in the future that is the former scenario, our first stepping stone must be a manned mission to Mars. Dr. Robert Zubrin details the challenges of a manned Earth-to-Mars mission. Challenges which, according to Zubrin, we are technologically more prepared to overcome than the obstacles of the missions to the moon of the sixties and seventies. Dr. Zubrin's relatively simple plan, called Mars Direct, could feasibly have humans on the surface of Mars within a decade. Zubrin also discusses the current predicament of NASA, the promise of privatized space flight from companies like SpaceX, and the larger implication behind the absolute necessity to open the final frontier to humanity-the human race's future as a species that takes the necessary baby steps away from the cradle that is planet Earth or, ultimately, perishes here.

  Trauma is a negatively life-altering event or ongoing situation that affects us in mind, body, and soul. As Bessel van der Kolk’s (2015) famous book title tells us, “the body keeps the score.” So does the human brain. Trauma, even when the event or situation is long in the past, can haunt us. We may feel overwhelmed with tumultuous feelings, such as depression, anger, shame, and grief. Sometimes it feels inescapable; even when we sleep, we have nightmares that pursue us like a hungry wolf, ready to gobble us up. Our body aches and recalls the feelings of the original event. Trauma is everywhere we turn.Because of this, it sometimes feels that all we are at our roots is our past. It has caused so many changes in us that we may end up thinking that it defines who we are as a person.But this is not the case. Yes, trauma can alter us, sometimes in surprising ways. But underneath it all, there is still the same spark of who we were before it happened.By committing to healing ourselves in body and mind, we can rediscover that spark. We can become ourselves again.We can become whole.

  The Reverend Gilbert White was the curate of the village of Selborne, a village in Hampshire, from 1784 to his death in 1793, living most of his life in the village. The book is in the form of a collection of letters to two friends, discussing the natural history of the areas that he knew, and natural history in general. White's intense curiosity and his love for the world about him flow through his simple, straightforward style, and a gentle sense of humour colours many of his anecdotes.  (Summary by Peter)

  Travels in Alaska - Three...

  'To the lover of pure wildness Alaska is one of the most wonderful countries in the world.'
  First published in 1915, Travels in Alaska is the last book that Muir wrote, detailing the adventures and experiences that were arguably most dear to him. Alaska's picturesque forests, grand mountains, and unique glacier range impacted Muir from the moment he first visited:
  'Never before this had I been embosomed in scenery so hopelessly beyond description… we must surely have reached the very paradise of the poets, the abode of the blessed.'
  As Muir expert Terry Gifford observes in the foreword, 'From the first trip, Muir set out to learn as much about the people as the glaciers'; and this willingness to surround himself in all aspects of the atmosphere is evident throughout, with beautifully detailed descriptions of everything from the tribes that he meets, to the canyons, rivers and animals he encounters.
  Muir's unwavering adventurous spirit shines through in Travels in Alaska; no challenge is too great and even when faced with the unimaginable – being caught near death between two icebergs while canoeing, or saving an inexperienced mountaineer from slipping and falling – he does not lose his faithful 'get up and go' attitude.
  Travels in Alaska details three of Muir's trips to Alaska: 1879, 1880 and 1890. Each one a refreshing account of the joys of exploring and the rewards of the outdoors: 'Never before had rocks and ice and trees seemed so beautiful and wonderful, even the cold, biting rainstorm that was blowing seemed full of loving kindness, wonderful compensation for all that we had endured, and we sailed down the bay through the grey, driving rain rejoicing.'
  Embedded with stunning metaphors, a dedicated love of Mother Nature and a desire to protect and preserve wildness, this book is an insight not only into Alaska, but Muir himself. The enthusiasm contained within these pages is infectious, and as well as making a powerful read, Muir will inspire you, too, to go out and experience the paradise that is natural wildness.

  A scrutiny of how algorithm has been widely used in order to perform any task has been done here. The step-by-step solution to any problem is an algorithm.  
  The set of rules and steps which should be followed so that the task is performed smoothly, is called an algorithm. It is the guidelines presented/ listed in a systematic way which is required while performing the task. 
  The era of modernization where computer holds almost all the importance is also based on an algorithm. There are multiple problem-solving operations which require certain guidelines so that the goals are achieved. The languages of the computer which builds a relation between machine and humans work on these algorithms. No wonder the world knows what to do and how but the computer needs guidelines! 
  The instructions provided by the user makes it possible for the computer to work out the problem-solving statement. There have to be some standards of the algorithm that the device should understand. The algorithm is not only used in computers but it also holds great utilization in cooking and mathematics. 
  The algorithm can be in various ways but as for coding there are has to be certain specific coded terms. The algorithm should be simple so that it is easy to understand and can be followed. There are various areas where algorithms are used in mathematics. The big problems which need expert solutions need proper methodology. This method is provided by algorithms. It is not necessary that the algorithms should be short. It varies from problem to problem. The mathematics subject has always been a tough one. Many difficult problems need proper step-by-step explanation. The different answers to various problems can be efficiently explained by algorithms provided. The simpler specifications help to solve bigger problems as well. The algorithm contains the constrained set of instructions in understandable language. The more procedure-oriented problems appear more need of algorithm is required. The algorithm used in computers is different based on the type of problem. The algorithm can be of several types in computers, such as string operator type, recursive backtracking and divide and operator. Randomized operator algorithms are also of great use. There are various properties of algorithms such as they should be input and output specified. They should be definite and effective. The finiteness of algorithm should be maintained by the means of input and output specified. It means that the input should be given to the processor and then output should be received. The moment when a computer receives the input, the command is achieved and it starts its working to produce the output. The relation between the input and output should be maintained. The algorithm should be specific and if these properties are hindered, the system is malfunctioned. The command and coding require a brief introduction. The algorithm provided is that brief instruction which acts as the helping hand for the coder. 
  Not only in computers, but even in mathematics, the formula provided is kind of a helping hand for any problem. The algebraic problems are in need of some pre-instructions which ensure the absolute results.

  As huge and prominent as it appears to us, our planet  and solar system are but small parts of our galaxy, a  massive assembly that spatters the sky with billions of  stars and that extends away from us for tens of thousands  of light years. And this galaxy of ours is in turn  but a small portion of the universe of trillions of other  galaxies that reaches outward for billions of light years,  back to the dawn of time.  This course places our local solar system into the  greater context to show where it all came from and  what its fate may be. We will study our sun and its  interior, learn about stellar red giants, white dwarfs,  neutron stars, and black holes, and encounter the  mysteries of dark matter and dark energy. We explore  the natures of the stars, what different kinds there are,  what makes them shine, how they are born, and how  they die, some with a whimper, others with explosions  that rock the cosmos. We then look to our galaxy of  stars, and then to the great variety of other galaxies, to  their clusters, and to their fiery interactions and collisions.  Finally, we encounter the universe as a whole,  the collection of all there is, which is still expanding  from its Big Bang origin of nearly 14 billion years ago.
