“If I had a time machine I'd visit Marilyn Monroe in her prime,” wrote Professor Hawking in his article “STEPHEN HAWKING: How to build a time machine,” in Daily Mail. I liked very much his idea and prepared to go back in time. I started with time travel research, reading reference books and articles, and exchanging emails with leading experts on time travel. Scholars most often suggest using the following time travel methods: to travel faster than the speed of light, to use black holes, cosmic strings, negative ener-gy, negative mass, exotic matter, or wormholes. After making some brisk calculations with my favorite pocket calculator, I came to the conclusion that the easiest, and financially accessible, way to travel back and forth in time is to build a wormhole. Constructing a wormhole is more or less clear, and I could make a time machine based on this technology in about a few months. ...

In this edition are presented the works by Alex Listengort, written in a period of time from autumn-2008 to may 2013. Here the reader may see a circulation of different topics, of questions and answers, embodied in Poems. These Pieces of Arts do Bless and Fill Up with a Special Energy that is familiar to every living creature, and that brings peace, eternity, divine presence and Miracle of life in all its forms. Searches for a meaning of life and its integrating into the life itself, eternal existencional questions, for which the author dares to give an answer in his poems. Themes of love and beguines, motherland, nature, time and something they call the God: all that finds its reflections in authors’ poems, but the main here are the questions of enlightenment, spiritual awakening of a human being, gaining happiness, abundance and awareness: of everything, that each of us insists to find on the line, of everything, that, as author says, no one had ever really lost, and what Is just temporarily hidden under a tricky veil, that is a part of a global plan, that is a special condition of this Game. Today in our hands we all keep a total...

A line of thought explored herein is the correspondence between cosmological phenomena and condensed matter physics, and therefore we can think that the quantization of orbit distances can be caused by superfluid helium quantization. This issue is explored by F. Smarandache and V. Christianto. Moreover, F. Smarandache also discusses possible new era of research that is pertaining to superluminal physics and instantaneous physics. Ion Patrascu and D. Rabounski discuss superluminality from their perspectives. And M. Pereira discusses his Hypergeometrical Universe model....

This book has six chapters. First chapter gives a brief description of biotechnology. Second chapter deals will proper proportion of mix of raw materials in cement industries to minimize pollution using fuzzy control theory. Chapter three gives the method of determination of temperature set point for crude oil in oil refineries. Chapter four studies the flow rates in chemical industries using fuzzy neutral networks. Chapter five gives the method of minimization of waste gas flow in chemical industries using fuzzy linear programming. The final chapter suggests when in these studies indeterminancy is an attribute or concept involved, the notion of neutrosophic methods can be adopted. The authors feel that the reader should be well versed with fuzzy models like neural networks, fuzzy relational equations, fuzzy control theory, fuzzy linear programming and neutrosophic fuzzy models like NRE together with a knowledge of the technical functioning of chemical industries....

2.4 Finding the MIX of raw materials in proper proportion and minimize the waste dust using fuzzy neural network. The study of proper proportions of material mix during the clinkerization process is very difficult due to inconsistency in the chemical and mineralogical composition and the variation of these characteristic affects kiln operation, fuel consumption, clinker quality and above all the amount of CKD vent into the atmosphere. Further the raw mix should maintain a fixed range for a specific quality of cement. The problem of satisfying this range involves lot of randomness and uncertainty, which in turn speaks about the desired quality of the clinker. ...

Under The Thelián Sky: Beyond the Great Unknown (updated cover)As everyone knows, God created mankind to his image (Genesis 01:27). What mankind does not know is that God did not create man on Earth, but rather on MARS! When Mars could not sustain life anymore, mankind had to escape the planet and colonized Earth. Many years later, a study was written about the survival of mankind in Sol Four (Mars) and its struggle in Sol Three (Earth). We proved to be a species that has survived wars, slavery and other forms of abuse — always holding on to our faith in God. Doctor Ajidán Edejèm, after finding out that his world was going to die, embarks in the dangerous mission to rescue as many people as possible and search for a new world. All the while, the government wants to keep everything quiet and even kill him for telling others about the unavoidable doom. “We discovered that the seismic activity is increasing and becoming more frequent causing volcanic eruptions, which increase the volume of sulfates in the atmosphere and break down Ozone. In other words, the atmosphere of this planet is bleeding into space. At the rate these p...

I’m Sean Morgan and my mission in life is to give hope to people who are looking for it. I’ve spent years discovering the most effective methods for self-transformation and empowerment from ancient eastern traditions to modern western research. I had to go on this journey due to intense mental, emotional, and physical illness. Now I’m sharing the most powerful insights and practices to provide guidance to those suffering with any or all of the following: low energy, low motivation, physical illness, anxiety, depression, and financial scarcity. The included workbook will guide you through the techniques that worked for me such as deconstructing beliefs, physical healing practices, visualizations, meditations, and journal reflections. You will also develop your understanding of neural pattern interruptions, emotional energy cycles, the correlation between social introversion and depression, and much more. By the end of this book you will know why patterns of negativity persist in ourselves and in the world. Second, you will understand what it takes to break free from patterns of victimhood, illness, depression, and fear. Thir...

Hi, I'm Sean Morgan. My mission in life is to give hope to people who are looking for it. In the past, I've worked with anxiety, panic disorder, depression, depersonalization, and extreme illness. I was hospitalized and medicated as a teen for panic disorder. The medication actually made things worse, and I found wellness through healthy lifestyle choices. In my twenties, I suffered from chronic Lyme disease and depression. It put me on a journey to discover as many healing practices as possible for my body and mind. It was only through the destruction of a precious relationship with my fiancee that I was willing to take responsibility for my mental health. I realized that I am 100% responsible for my own circumstances through my thoughts, feelings, and actions. Now I’m happy to say that I'm healthy in body and mind. If I could have just one wish for people struggling, it would be to experience the same life-changing revelation regarding responsibility. I always wanted to “make a difference”. I tried to become powerful by studying business. Then I realized that my vocation was to work directly in a caring profession. ...

A book on the contrasts between the eastern Asian culture versus the western culture on topics such as education, medicine, science, and politics.

Is oriental culture a kind of science? There lies a crucial difference in that Western science seeks the exterior solutions outside the heart. However, our ancient sages illustrated that humans are an integral part of the universe, and all the phenomena never skip out of the heart. And very fortunately, many wise men did succeed in cultivating their hearts to testify to the profound truth. So our Eastern classics focus on our inner cultivation. However people, including the overwhelming majority of the Chinese, would regard such education as being an extra (to life or science). Please contact the corresponding Taiwan or Singapore websites, where there are plenty of English versions of texts and videos of Buddhism, to request the standard translation. “What is Dao (Tao)? It is the natural principle all over the universe, the natural order, the essentiality of nature. The great universe has its order and rule, where the education of ancient sages roots. Education stems from here, and a human being has to obey the natural principle –Dao. In our Chinese notion of the integral of humans and nature; heaven, earth and human are...

The present book covers a wide-range of issues from alternative hadron models to their likely implications in New Energy research, including alternative interpretation of low energy reaction (coldfusion) phenomena. While some of these discussions may be found a bit too theoretical, our view is that once these phenomena can be put into rigorous theoretical framework, thereafter more 'openminded' physicists may be more ready to consider these New Energy methods more seriously. Our basic proposition in the present book is that considering these new theoretical insights, one can expect there are new methods to generate New Energy technologies which are clearly within reach of human knowledge in the coming years....

In the preceding article we argue that biquaternionic extension of Klein-Gordon equation has numerical solution with sinusoidal form, which differs appreciably from conventional Yukawa potential. In the present article we interpret and compare this result from the viewpoint of EQPET/TSC model described by Takahashi. Further observation is of course recommended in order to refute or verify this proposition....

In this theoretically sophisticated monograph Dr. Alex Battler formulates a new ontological interpretation of the category of force: - a definition of force as an ontological category; - the manifestation of force in the inorganic world within the framework of the idea of the Big Bang; - a definition of force in the organic world to determine the boundary between life and nonlife; - a solution to the mind–body problem (i.e., what consciousness and thought are), which has led me to a new formulation of the concept of Progress. ...

This book was intended to discuss some paradoxes in Quantum Mechanics from the viewpoint of Multi-Valued-logic pioneered by Lukasiewicz, and a recent concept Neutrosophic Logic. Essentially, this new concept offers new insights on the idea of ‘identity’, which too often it has been accepted as given....

2 Lukasiewicz Multi-Valued-logic: History and Introduction to Multi- Valued Algebra 2.1 Introduction to trivalent logic and plurivalent logic We all have heard of typical binary logic, Yes or No. Or in a famous phrase by Shakespeare: “To be or not to be.” In the same way all computer hardwares from early sixties up to this year are built upon the same binary logic. It is known that the Classical Logic, also called Bivalent Logic for taking only two values {0, 1}, or Boolean Logic from British mathematician George Boole (1815-64), was named by the philosopher Quine (1981) “sweet simplicity.” [57] But this typical binary logic is not without problems. In the light of aforementioned ‘garment analogue’, we can compare this binary logic with a classic black-and-white tuxedo. It is timeless design, but of course you will not wear it for all occasions. Aristotle himself apparently knew this problem; therefore he introduced new terms ‘contingency’ and ‘possibility’ into his modal logic [5]. And then American logician Lewis first formulated these concepts of logical modality. ...
