Imagine how much more fulfilling it would be, if you could experience an entire lifetime free from even the slightest fear associated with your eventual death.What if you could finally know that though the physical body will surely fail, nothing can affect the eternal, immortal, ever-lasting being that you are in your purest form?Suppose that reading one book could answer the most mysterious questions about what happens when you are dying and what happens to your consciousness once that takes place.You are about to read that book.In reality, there is no death at all. It is an end to your most recent journey - an exploration into temporary physicality, but it is not the only journey you will take - and will certainly not be the last.Death of the physical body is certain. It is time that you know what awaits you when that happens.No one in the history of the earth has ever 'died.'They have simply changed form.
Kevin Morrison had it all. A house he worked hard for, a loving wife, and three beautiful children. But it wasn't until his marriage ended that he realized what the void he'd felt almost all his life meant. Coming out as a gay man at thirty-six is not an easy feat, but he is determined to be true to his heart. Meeting a man who shares his values, and is good with his children would be a bonus, but when the guy arrives in a uniquely wrapped package, and has very specific handling instructions, Kevin needs to decide if he's up for that kind of love. Obsessed with order and symmetry, and a paralyzing fear of germs, Cedric Haughton-Disley has lived with isolation and loneliness as long as he can remember. Desperate to be normal, he makes some much-needed changes in his life. If he can commit to his treatment, he might very well be able to procure some quality of life... even if that's all he can get, as finding love and having a relationship are only possible in Cedric's wildest dreams. But when a chance encounter leaves Cedric wishing for more, he decides to take a leap of faith, and pursue the guy he wants.Together the two men make an unlikely match. Cedric needs organization, and Kevin represents chaos. In order to stay together they both need to compromise, but will they be able to deal with Cedric's issues and the potential disaster, or let it break them apart?
Computer Science Design Series Programming with MFC & Visual C++ Prerequisite: Microsoft Visual C++ 6.0 or equivalent. Recommended especially if you are new to MFC: Jeff Prosise "Programming Windows with MFC" (1337 pages, ISBN 1572 316 950) This text is about how to use Windows Microsoft Foundation Classes (the MFC) and the software program Visual C++ to write programs using windows without knowing how to write the complex code that produces the windows. The MFC/Visual C++ combination immensely simplifies the writing of any program that uses one or more windows. Second, this is about learning how program with MFC from the bottom up so that you can produce the projects presented here. Many MFC classes and functions replace/obsolete many C, C++, and C# classes and functions. Consequently you can go directly to MFC, and save a lot of time and energy. Programming with MFC allows you to work at the top of the C hierarchy, while avoiding the limitations of C, C++, and C#. This text BEGINS to show you how to program with MFC by using Visual C++ to produce skeleton programs on the Visual C++ screen. Skeletons that include code producing the windows in which your programs will be presented. For example, creating front panels using dialog boxes in which you place controls (push button, combo box, slider, text box, etc.) in precise positions and how to initialize/program the controls. We say begin, because learning how to program in any language is an endless task. Especially MFC with its hundreds of functions. At this point we believe it is very important that you view the table of contents to know what we have chosen to present from the thousands of possibilities. We believe our choices represent the basic know-how one needs to get going with MFC. There is an unavoidable "cook book" element to using Visual C++ that dictates how to create the skeletons, and where to enter code in the skeletons. This text is different. Instead of referring you to code on a disk (with few if any comments), and instead of offering partial explanations in the text, requiring you have to go back and forth from book to disk, and wondering what to do next, we show you how code is written that actually creates programs that run on any computer using the windows operating system. That is why only the Visual C++ disk is required. We briefly explain most of the code lines used to produce the functions required by the projects. We expect the reader to have a basic programming capability. This text uses the Jeff Prosise text "Programming Windows with MFC", as a very useful reference.With Jeff Prosise's text supporting us we were able to write programs using windows, while knowing nothing about windows programming and very little about MFC and the various C languages. JP's text gave us a great start with the design process producing programs presented in one or more windows. That experience brings us to this point. We wrote this text, because even with the JP reference we learned that we had to answer many "How-do-we-do-that?" questions. Answers we needed in order to produce programs that run. Answers we share with you by presenting selected topics in the form of working projects. Many types of programs can be implemented with MFC. We focus on dot exe (name.exe) executing programs. JP's text makes very clear the fact that there is much, much more to MFC then what is presented here.
With the King of the Franks fighting a civil war and a Saxon king on the verge of death Hrolf the Horseman embarks on a series of raids and attacks to make his land more secure and to give his son an inheritance. When he raids the Seine, along with a fleet he discovers the treachery of erstwhile allies. His son, Ragnvald enjoys command for the first time. We see two leaders with the same blood as they take pieces of Frankia to make the land that will, one day, be Normandy!

"Dear God in heaven, thank you!" Adam's relief however was short-lived, for when he glanced over at Janet, who was still searching through the ruins for Michelle's body, he froze in terror. "Dear God, Janet, look behind you!" he yelled. She turned, and let out a piercing scream as she stared at a heap of rubbish that had started to shudder and crumble as something bubbled out from within. It was as if the earth itself had opened up and the huge mound seemed to explode, as bits of scum and liquid bubbled down the sides of it like brown feces oozing from an open sewer. From the foul-smelling decay rose a mammoth insecta. Hideously beautiful, in its full genetic completion, it was the alpha queen, ten feet in length; the ghastly creature crawled out of the rubbish and sprang into flight! Terrifying and obscene, its hairy legs bent and clinging with feces, a huge egg sac hanging from its abdomen, it hovered above Janet, its twin heads and proboscis, throbbing, and poised to drain Janet of her blood. Horror-stricken, she fell to her knees! "Oh my God," she thought. "I'm going to die! I'm going to die!"
This text is about solving various types of equations using practical mathematical methods. Only the essentials of each topic are discussed. This is not about proving theorems, taking limits, or other matters important to mathematicians. "However, the emphasis should be somewhat more on how to do the mathematics quickly and easily, and what formulas are true, rather than the mathematicians' interest in methods of rigorous proof." Richard Feynman Concepts from Linear Algebra - the determinant, the finite matrix, the eigenvalue - are presented without the distractions of mathematical rigor. You learn solution methods that do not involve guesses. Methods you implement in a straightforward manner. The operational calculus can be traced back to Oliver Heaviside. Though many scientists preceded Heaviside in introducing operational methods, the systematic use of operational methods in physical problems was stimulated only by Heaviside's work. The methods he created are undoubtedly among the most important ever created. Heaviside was criticized for his lack of mathematical rigor. Yet his numerous mathematical and physical methods and results proved to be correct when mathematical rigor was incorporated. The Laplace Transform, a basis for a modern day operational calculus, is a straightforward technique for solving ordinary, partial differential, and, with a few complications, difference equations and a type of integral equation. On the other hand the Z transform solves difference equations without complications. And, Heaviside's differential operator D = d/dt augments the transform methods. The Laplace Transform transforms equations in one real variable domain, usually the time t domain, to a complex variable domain where the problem at hand is essentially solved. The inverse transform from the complex variable domain to the real variable domain completes the solution. Understanding the inverse transform requires knowledge of the theory of functions of complex variables. Our main interest in functions of a complex variable is integration, because integration of the complicated integrals of inverse transforms is amazingly simplified. The methods of the differential and integral calculus are extended to complex numbers and functions of complex variables. The results produce tremendous analytic methods. We show how ordinary differential equations. systems of ordinary differential equations, partial differential equations, and difference equations are readily solved by transform and/or differential operational methods. We show that each type of equation is solved in essentially the same way. We just define the Fourier Series, and show how to create Fourier series representing waveforms. Integral Equations - This is a hugh subject, which we limit to how the Laplace transform solves integral equations that include the convolution integral. Galois Finite Fields GF(2m) are not used to solve equations per se. They are used to implement functions such as error correcting codes, speech recognition, phase array antennas, and Doppler radar. Functions NOT implemented here.

Help your students explore the symbols of Christianity, Judaism, Islam, Buddhism, Taoism, Hinduism, Sikhism, Paganism and Humanism. You will find 68 printable pages to help your students learn about the most popular religious symbols of the world. Students use a phone, tablet or laptop to search online about each symbol and its history, what this image symbolizes, interesting facts about this symbol and its religion, and wise words or quotes from its worshippers. Students are encouraged to consider why people find peace and happiness in a particular religion, and to think about how we know that a specific religion is right for us. Students compare and contrast the different symbols within one faith and across different faiths. Why do Christians use the cross, the fish (ichthus), praying hands, and NOTW? Why do Muslims use a crescent and a star? Why do Buddhists use a wheel? Why do Taoists use the yin and yang? Why do Pagans use a pentacle? why do Humanists use the Happy Human? Help your students learn more about the religions of the world, while encouraging respect and appreciation for the diversity of spiritual quests across the planet. Note: this workbook does not present one religious experience as better than or worse than another. All questions require investigation and thought, and student responses are based on where their research leads them. It is good for students to learn that some religions focus on human experiences while others focus on the divine, and that some religions affirm only one divine being while others adopt many or none, and that some religious expressions focus on inward development while others focus on the outward performance of kind acts. As a teacher, your duty is to open the eyes of your students to the world and its diversity so that they can make an informed choice. Don't be afraid to explore. Remind students that their choice is always THEIRS, and that your duty is to expose them to what other cultures do and say and think.
How do you get a student to talk about death, their own or that of someone they love, without bringing them to tears or pushing them into painful silence?

For some of us, childhood is only a nightmare away. When Stephen Connolly, a self-taught artist, drops out of Cambridge University to paint in the slums of 1970s and 1980s Liverpool, it soon gets much closer than that. He struggles against both anti-Semitism and his brutal Jewish mother, against merciless poverty and corrupting affluence. He is pulled apart by two passions, for bed-mate and for soul-mate. The prostitute Anna teaches him urban survival and the petite lecturer Jenny clings to him like a mad mollusc to an unstable rock.The city is in turmoil from mass unemployment and riots. But the greatest threats to Stephen's sanity are the monsters and imaginary playmates that emerge from the fog of his solitary, haunted childhood.Rough, sinister, bohemian, the story battles its way to a happy ending through tragedy, grim humour and the bastard miracle of love. Try this for something scarier and more hard-edged than the average historical romance.

Algebra - A Clear Presentation This is about the fundamental ideas of Algebra, and understanding why and how Algebra works. The present text is unusually accessible to readers who want to acquire algebraic skills. The clear presentation allows the reader to focus on the crucial facts of Algebra. The text is not cluttered with unnecessary details. That is why 500 plus pages are not necessary. We do not use the devastating phrase "it is obvious", because nothing is obvious to a person learning any subject. The ideas of digit position and digit position weight are introduced to show how integers greater than 9 are created. In this way understanding replaces rote learning. And, the real number system is reviewed. Fractions appeared when division created remainders. Fractions are numbers. The text shows how fractions are manipulated by the four operations addition, multiplication, subtraction, and division. Decimal integer and fractional parts are created when q divides p in the fraction p/q. The ideas of digit position and digit position weight are extended past the decimal point to show how the fractional part is valued. The text shows how to manipulate decimals. A focus on general methods for solving algebraic equations allows one to know how to solve any problem. The numerous special methods are distractions that have limited value. Sometimes an equation is not in the desired form. Algebraic operations are used modify the form of the equation by making the same changes to both sides of =, which does not upset the equality. A polynomial in one variable x is defined and its essential properties are presented. The text shows how to manipulate polynomials. The Remainder Theorem is explained. The theorem simplifies finding factors of polynomials. Newton's method for finding polynomial zeros is explained. Cramer's Rule is the straightforward way to find solutions by determinants of algebraic equations. How to find solutions of linear equations by addition, subtraction or substitution is also explained. The formula solving quadratic equations is derived and explained. An exponent n is a symbol written above, and on the right of, another symbol known as the base x as in x to the n. The text shows how arithmetic operations manipulate exponents. The Binomial Theorem shows how to expand (a+x) to the n when a and n are any numbers, positive, negative, integral or fractional. The Exponential and Logarithmic Functions are explained. The text shows how to manipulate them. Many problems are simplified when a rational function, the ratio of two polynomials, is decomposed into a sum of partial fractions with denominators of lower degree. Partial fractions have many applications such as simplifying many algebraic problems as well as the important inverse Laplace Transform process. Matrix algebra allows one to write and process equations efficiently. Furthermore, in many problems, the matrix format makes the next step easier to perceive. The concept of Mathematical Induction is explained and applied to problems. The presentations are eminently clear, because they are based on the policies assume nothing and nothing is obvious. The present text's contents are topics one actually uses when solving algebraic problems.

Electrical and Electronic Engineering Design Series Volume 5 Analog Filter Design This university level Electrical Engineering text is for anyone who wants to know how to design analog filters. A filter is a circuit that has a specific frequency response, which defines how signal frequencies amplitudes are modified. The present text is unusually accessible to readers who want to acquire the skills of analog filter design. We present a thorough foundation so that you can proceed to learn how to design any filter. This text is different from other filter design texts, because we actually design circuits, and not just talk about them. And, we ask you to work hard doing experiments so that you acquire real world experience with commercially available electronic parts. This is about real learning. We do not use the devastating phrase "it is obvious", because nothing is obvious to a person learning a subject. Eight experiments are included that give life to the text's contents, and provide the reader with real world experience with making measurements, using instruments, and learning about all kinds of parts. We consider the experiments to be significant learning activities. The analog filter design process is presented here for (1) the Bell Telephone Laboratories constant k, and m derived ladder filters, and (2) the modern Butterworth, Bessel, Chebyshev, and Inverse Chebyshev transfer functions and their synthesis methods. The designs produce filters one can build and use. Spice programs verify performance. The text starts with a presentation of the properties of four terminal two port networks. The two port equations and tables provide significant support for the filter design processes. The equations of the Bell Telephone Laboratories LC ladder filters are developed in a straightforward manner. The underlying idea is that of image impedance, which allows for cascading of filter sections. Spice programs plot filter transfer functions. The lattice filter structure is not discussed. The design of modern LC analog filters starts by showing how filters are specified. The Butterworth, Bessel, Chebyshev, and Inverse Chebyshev approximation methods of transfer functions T(p) are presented. The T(p) are converted into filter circuits by the transfer impedance synthesis method or the Darlington insertion loss synthesis method. Transformation equations convert low pass filters into high pass, band pass, and band reject filters. We show how to write AC analysis and TRAN transient response Spice programs that document filter performance.We include useful experiments that give you real world experience. We consider the experiments to be significant learning activities. The experiments include elementary RLC filters, Bell Telephone Laboratories filters, active filters using op amps, and filters derived via approximations. The presentations are eminently clear, because they are based on the policies assume nothing and nothing is obvious. The present text's contents are topics one actually uses when engaged in analog filter design.
Electrical and Electronic Engineering Design Series Vol 3 CMOS Circcuit Design - Analog, digital, IC Layout This university level Electrical Engineering text is for anyone who wants to know how to design products using CMOS circuits. The present text is unusually accessible to readers who want to acquire the skills of CMOS circuit design as well as the skill making Integrated Circuit Chip Layouts. We present a thorough foundation so that you can proceed to learn how to design and layout CMOS circuits. This text is different from other CMOS design texts, because not only do we actually show how to design CMOS circuits selecting transistor Length, Width and the correct value of mobility (a small detail that is usually overlooked if not ignored) we show how to make accurate, functioning circuit layouts that can be used in a chip. Furthermore we ask you to work hard drawing over 60 layouts that give you real world experience. This is not about logic design. This is about IC design from basic circuits to IC layout. CMOS technology is the preferred technology for implementing modern digital and analog integrated circuits. We show, step by step, how layouts are made that conform to Mosis rules. A brief review of MOS transistors sets the stage for CMOS circuit design. Digital circuits with no memory implement logic equations as sums of minterms (OR of ANDs) or products of maxterms (AND of ORs). We show how to design circuits such as NOT (Inverter), NAND, NOR, XOR, Multiplexer, and Adder. As we proceed we show how to plan and execute layouts for each circuit. One bit digital circuits with memory are used in state machines. The RS Latch is the most elementary one-bit circuit with memory. Latches do not have clock inputs, whereas flip-flops and edge triggered flip-flops are one-bit memory circuits with clock inputs. The flip-flops are synchronous circuits. We show how to design and layout the RS Latch and the D edge triggered flip-flop. We show that the JK design and layout is a straightforward adaptation of the D design and layout. The D and JK edge triggered flip-flops are the flip-flop circuits in commercial use today. Next the emphasis is on digital circuits that are an assembly of identical cells, such as the cell of a shift register. The integrated circuit layout of an assembly of cells is an orderly, repetitive pattern. Orderly, repetitive patterns are intrinsically free of layout errors. We say orderly layouts are mandatory for non trivial circuits (random logic layouts are high risk). We show how to make orderly systematic layouts, and how to write Spice programs that evaluate their performance. We design and layout well known digital circuits such as shift registers, storage registers with load control, registers on a bus, and programmable logic arrays of logic with no memory. The well known current mirror, differential amplifier, operational amplifier, resistors and capacitors are designed and their performance is evaluated by Spice. Layout procedures for the circuits as well as the resistors and capacitors are presented. Spice is used to plot DC response, AC frequency response, and TRAN transient response performance of circuits that are analyzed and designed in the text. We show how to write these programs. We ask you to draw over 60 layouts, which we consider to be useful experiments that give you real world experience. We consider drawing the more than 60 layouts to be a significant learning activity. The presentations are eminently clear, because they are based on the policies assume nothing and nothing is obvious. The present text's contents are topics one actually uses when engaged in CMOS circuit analysis and design.
This is about the fundamental ideas of Arithmetic, the theory of Arithmetic and understanding why and how Arithmetic works. This is about effective use of the practical procedures for addition, multiplication, subtraction, and division. Practical procedures you use when doing Arithmetic.This is about what are now standard algorithms for integer addition, multiplication, subtraction, and division that are recognized by the world wide mathematical community. Knowing and understanding the algorithms means one has moved beyond rote knowledge of arithmetic.Integer division creates simple fractions, which can be converted to decimal fractions. We present the theory of fractions and decimals as a straightforward extension of integer arithmetic.The basic laws defining operations are presented in the last chapter in order to avoid piling on new information in earlier chapters. The laws make very clear the operations on numbers that are permissible, and why. Studying the laws reviews the entire subject.In this text know that elementary algebra is used for general explanations such as if n is a number then n+1 is the next number, and specific numbers are used in examples. And, instead of taking up many pages with arithmetic problems, the reader is asked to select pairs of numbers to add, multiply, subtract and divide. However fraction and decimal problems, and their solutions, are included.The Standard Arithmetic Algorithms The word standard implies that we can order a document from a recognized Arithmetic Standards organization. We cannot do that, because we have not found such an organization. Nevertheless the world wide mathematical community recognizes what have evolved into standard algorithms for integer addition, multiplication, subtraction, and division. There are minor variations from country to country that are of no significance, because the underlying mathematical ideas are the same.We describe and fully explain the standard algorithms for addition, multiplication, subtraction, and division. The explanations emphasize ideas and procedures that always produce a solution. Perhaps you will agree with us when we say these algorithms are extraordinary discoveries.An algorithm is a procedure, requiring no creative skills of the user, with precise instructions, specifying a finite number of steps, so that sooner or later the procedure ends.A specific virtue of the arithmetic algorithms is that they solve an N digit problem one digit at a time. Repeat: one digit at a time. In other words one N-digit problem becomes N one-digit problems (one 5-digit problem becomes five 1-digit problems).This is important, because one-digit problems are done in one's mind.Algorithms are used, because they are methods that show how to solve every possible problem. Algorithms always produce a solution.We believe knowing how to apply the algorithms means one understands what arithmetic is about.Using the algorithms with understanding enhances your mathematical skills. Progress is subtle, and real. Know this about the relationship of practical procedures to the algorithms.The practical procedures implementing the standard algorithms use the algorithm's steps in a subtle way in order to be efficient. Consequently the procedures seem to be very different from the algorithms. They are not.Who can benefit from reading this text? Anybody who wants to be effective when doing Arithmetic. You may be a student who suspects he/she is being short changed by the system. You may be a school teacher, not trained in math, who is assigned to teach Arithmetic. You may be a parent, concerned about what is not taught in school, who is willing to make the effort to introduce these ideas to your children. You may be a person who wants to improve your math capability. Perhaps who is anyone who wants to know, and who wants to be able to do.
