Annihilation Method + Bonuses Style Neil Strauss Seduction Mystery PUA
AVI/MP3 | 5.5GB

This is the REAL Annihilation Method by Neil Strauss AKA Style. There are a lot of phony ads on here which use "annihilation" in the title to grab your attention, this is the real thing. Neil Strauss (aka Style) - immortalized by the bestselling book The Game (as both the Author, and one of the main characters...) created a buzz recently with the release of his infamous 'Annihilation Method' on DVD.

Originally the Annihilation Method was taught to the Final Five, who paid thousands of dollars each to attend the exclusive seminar. Strauss taught these final five guys his 'most powerful pick-up technique' after he announced he was 'leaving' the community.

CD's:

* CD #1: Breaking Through Your Sticking Points - In this special CD, I go through the most common (and crippling) problems men face not only in dating, but in their inner game as well. You get to hear me candidly work through one sticking point after another (and chances are, most of them relate directly to YOU).

* CD #2: In The Trenches - In this CD, you'll get to hear me break down real, live field reports from students step by step. You'll see common situations many men run into, and how to do the right things and avoid the wrong moves.
Listening to this could be the "tipping point" that leads you from having frustrating and boring nights of the same old routine ...to having exciting new adventures whenever you want.

* From Stumble To Seduction - This is where I bring things to the next level. I'll give you a crash course in dealing with the toughest problems guys face -- including how to get out of the dreaded friend's zone and damage control techniques to win any girl back, even after you think you've "blown it."
How? Because I walk you through my own personal history ...and show you the roadblocks I faced and give you a map to easily get around them.
Plus, you get the shortcuts I found that will put you at the level where women come up and approach you ...instead of the other way around.
As if that wasn't enough, I've gone ahead and done something NO OTHER pick-up guru has ever done.
I've actually gone back and interviewed EX-GIRLFRIENDS about how I picked them up ..and what worked on them!
Seriously, you get to hear - straight from the source - what was going through their mind as I was actually running game on them!!!

* Online Personals - Your Endless Supply Of Beautiful Women. An ex-girlfriend I met online spills her guts and tells you various internet tactics I used to get her wanting to sleep with me before we even met! And the best part is, these tactics will work on ANY girl online.

* EXPOSED - A Woman Reveals How To Make Threesomes Happen! This was probably my favorite interview. I was actually nervous calling this girl up and asking her about this topic. But to my surprise, she was TOTALLY open about it and shared with me exactly what I did right to get her into bed with another woman for the first time in her life. When you hear this fascinating interview, you'll never be nervous about going for a threesome again. This is proof that they want it too ...and what's more, you'll hear exactly what works ...straight from a woman!

* From Her Perspective - Inside Virgin Territory. In this interview, the girl I'm talking to was a virgin with no thoughts of having sex before marriage... until I came along. In this eye-opening expose, we talk about the tactics you can use to win over the hardest cases.
Plus, you'll discover how to do it with integrity.

And last, but certainly not least, Mystery and I get on the phone with each other to seriously talk about our own thoughts and feelings on the art and science of pick-up.
* Confessions Of The World's Greatest PUAs - Mystery & Style. In this interview, you can hear Mystery and I go head-to-head as we debate, share tips and ideas, and develop brand new tactics right before your ears! We've been called the dream team, and now you'll get to hear why!

Texts
In addition to all the transcripts of the audio CDs, you'll receive my never-before seen Mystery's Lounge Archives!
I took the best posts of mine from the super-elite Mystery's Lounge message board and compiled them into a series of "PUA Encyclopedias" dealing with five very specific issues...

* Volume 1: The Origin Of Style - How To Transform From Chump To Champ In No Time! If you've ever felt you're a "loser" who needs to turn his life around, you can see how I did and apply my same techniques to YOUR life.

* Volume 2: Closes - Creating A Physical Attraction. Ever reach the point where you know you should try to "close the deal" but don't know how? I was there for a long time, but I figured out how to get past it, and I'll share with you all my best secrets for getting past the "point of no return."

* Volume 3: Sticking Points - How To Get Past Any Obstacle In The Pickup. We all run into problems from time to time, but it's important to know how to get through them. In this volume, you'll read personal field reports where I show you how I brought myself and other PUAs through their most daunting sticking points!

* Volume 4: Jealously Guarded Inner Game Techniques. Why are they jealously guarded you ask? Because once you know these, you'll be the Alpha Male in any situation. I'll show you how to deal with the problems that are really holding you back from life.

* Volume 5: The Next Level - How To Get Models And Threesomes, Guaranteed Lines And Routines For Advanced Situations. If you thought some of the stories in The Game were wild, wait until you read these, and how you can use them to attract the kind of women your friends will be green with envy over!

* The Seduction Blueprint. The problem with most seduction systems is that they don't really help you apply the material. Not true with the Annihilation Method. I designed a blueprint you can use to fast-track the entire process and master the Annihilation Method immediately!

* CONFIDENTIAL - Instant Pickup Supply. Ever run out of material out in the field? No more! This special book is so small, you can easily fit it in your pocket and use it as reference IN THE FIELD. It is chock-full of the best openers, routines, and DHVs there are from the Annihilation Method, so you'll never be at a loss for words in the field again!

The Teaching Company: Physics in Your Life

The Teaching Company: Physics in Your Life | 5,7 GB

Taught by Richard Wolfson | Publisher: The Teaching Company | ISBN 1565859383 | $374.95
The Great Courses: Science and Mathematics, Course # 1260 (36 lectures, 30 minutes/lecture)

This amazing lecture set from the esteemed Teaching Company demystifies physical science. Professor Richard Wolfson teaches Physics conceptually, so that the listener can understand the amazing science without being overwhelmed by the mathematics. 1. Realms of Physics 2. The Amazing Disc 3. The Wonderful Wave 4. Seeing the Light 5. Is Seeing Believing? 6. Music to Your Ears 7. May the Forces Be With You 8. Aristotle's Revenge 9. Going in Circles 10. Taking Flight 11.

Why does a curve ball curve? Why does ice float? What's the perfect way to cook egg custard? How do CDs and DVDs work? Why don’t your legs break when you jump off a chair? What keeps a moving bicycle from falling over?
These questions involve physical principles that relate not only to interesting aspects of our daily lives, but also explain such phenomena as the cause of hurricanes, the formation of neutron stars, the ability of water to dissolve different substances, and other fundamental features of reality.

Therefore, this course that explores the physics of everyday events is not just informative and fun, it has the potential to lead to a deeper understanding of the universe.

But it takes a superb teacher to make these connections—to start with a nuts-and-bolts description of how a refrigerator works and end up with a profound insight into the ultimate fate of the cosmos.

Professor Richard Wolfson of Middlebury College is the ideal teacher to take you on this journey. The New York Times praised him as "absolutely stellar" in his Teaching Company course on modern physics, Einstein's Relativity and the Quantum Revolution: Modern Physics for Non-Scientists. Now he brings the same enthusiasm to "everyday" physics, dealing with our basic understanding of the physical world as it applies to commonplace technologies and natural phenomena.

A Non-Mathematical Course Where "Seeing is Believing"

Physics in Your Life is more than a course in physics and more than a laundry list of "how things work." In fact, it combines the two, offering a back-and-forth interplay between everyday applications of physics and the concepts needed to understand them.

"My approach is entirely qualitative," says Professor Wolfson. "I believe you can understand physics, and understand it deeply, without using mathematics."

How does he do it? In the spirit of "seeing is believing," he uses an impressive array of experiments, gadgets, props, computer animations, short videos, diagrams, and pictures. Like Mr. Wizard of the classic TV science series, Professor Wolfson is a born showman. Among his hands-on demonstrations:

* A blown-up balloon is bathed in super-cold liquid nitrogen to show the contracting effect that heat loss has on the air inside the balloon.
* Professor Wolfson cranks a muscle-powered generator to demonstrate the surprising effort required to produce a mere 100 watts. Imagine if you had to generate all your electricity this way!
* A giant magnetic coil on a rotating shaft reveals the ingenious simplicity of the electric motor, used in everything from electric toothbrushes to locomotives.
* A curious phenomenon unfolds as a magnet is dropped through a hollow aluminum tube. Aluminum is non-magnetic, which means the magnet won't stick to it. But can you guess what happens?

You will also see experiments with lasers, lenses, bowling balls, gyroscopes, musical instruments, and more. And Professor Wolfson walks you step-by-step through the processes by which computers compute—from the level of electrons moving through semiconductors to binary bits, bytes, CPUs, RAM, all the way up to text and pictures appearing on your screen.

What You Will Learn

This course is organized into six modules, treating five specific realms of physics and their related applications, plus a sixth area devoted to a potpourri of topics:

Module 1 (Lectures 2-6), "Sight and Sound," begins with the technology behind CDs and DVDs, using these devices as a springboard to study light, sound, and other phenomena. You will explore how these principles relate to such topics as rainbows, optical fibers for communications, musical instruments, and laser vision correction.

Module 2 (Lectures 7-12), "Going Places," looks at motion and its connection to modes of transportation such as walking, automobiles, airplanes, and interplanetary probes. This module is based on Newton's laws, generalized to include such topics as fluid motion, conservation of energy, and the dynamics of space flight.

Module 3 (Lectures 13-18), "Plug In, Turn On," looks at the intimate connection between electricity and magnetism that is at the heart of technologies from electric motors and generators to videotapes and credit cards. Electricity and magnetism join to make possible electromagnetic waves, which enable the growing host of wireless technologies.

Module 4 (Lectures 19-24), "From Atom to Computer," starts with the element silicon and builds through progressively larger scales-transistors, logic circuits, microprocessors, motherboards, and peripherals-to create a conceptual picture of how a computer works.

Module 5 (Lectures 25-30), "Fire and Ice," introduces heat with topics ranging from physics in the kitchen to Earth’s climate and how humans may be altering it. Also covered are thermal responses of materials, including the unusual behavior of water in both liquid and solid form. The module ends with the second law of thermodynamics and its implications for human energy use.

Module 6 (Lectures 31-36), "Potpourri," offers a final miscellany of topics in physics: the workings of the space-based Global Positioning System; rotational motion in phenomena from dance to pulsars; lasers and their many uses; nuclear physics and its multifaceted role in our lives; the mechanics of the human body and how physics enables us to explore the body through medical imaging; and the evolution of the universe from the Big Bang to you.

From Everyday Examples to Universal Principles

The beauty of this course is that it takes you from the specific to the general. "This is not a standard introductory physics course," says Professor Wolfson. "It’s not a course that's going to lay out a lot of physical principles, and then give you a few minor examples of them. Rather, it's going to focus more directly on the application of those principles in your everyday life."

For example, at the beginning of Module 1 you delve into a mystery that may have long puzzled you: How are music and images encoded in the plastic discs that are CDs and DVDs? As you discover how microscopic pits on a rotating disc are interpreted as ones or zeroes by a laser optical system, Professor Wolfson relates these processes to principles you will encounter later in the course:

* Discs rotate, as do objects from car wheels to planets.
* Discs store information, a role they have in common with magnetic tapes, credit-card strips, semiconductor electronics, phonograph records, and DNA molecules.
* Discs are read with an optical system that involves lasers and the reflection, refraction, and interference of light.
* The stream of information coming off a disc is manipulated by physics-based electronic circuitry. It is then converted into light and sound using a variety of physics principles.

"CDs and DVDs are metaphors for almost all of physics," says Professor Wolfson. Many different disciplines—from quantum physics, to optics, mechanics, and electronics—are involved in making CDs and DVDs work.

Bringing Physics Down to Earth

Physics can get complicated, and whenever the discussion threatens to become too abstract, Professor Wolfson pulls you back to Earth with a memorable explanation or analogy:

* On the information content of a CD: "Brahms’ Symphony No. 3 as recorded on a disc is nothing but a single number. It’s a binary number with many, many digits. When you go out and buy Microsoft Office to put on your computer, it's nothing but an enormous binary number. When you write your Ph.D. thesis, there’s nothing but a single, large number."
* On the nature of waves: "A wave of people in a stadium is a true example of a wave. The disturbance consists of the people removing themselves from their seated positions, standing up, and sitting down again. That disturbance moves around the stadium, and it carries with it the energy that it takes to lift a person out of his or her seat—but it does not move the people around the stadium. A wave, then, is a traveling disturbance that carries energy, but it doesn’t carry matter."
* On the energy source of hurricanes: "A hurricane works by the latent heat of water evaporated from the ocean, released in the air to drive the hurricane. Similarly, in a double boiler, latent heat from the boiling water is released in contact with the bottom of the upper pan, and that's what causes the food to cook."
* On computer "crashes": "In a computer hard disc, there is a head that literally flies, held aloft by aerodynamic forces. The distance is on the order of one millionth of one meter. A disc crash is like an airplane crash. The flying disc hits a particle of dust, loses those aerodynamic forces, and crashes into the disc, damaging the surface—and there goes your Ph.D. thesis if you haven’t got it backed up!"

Clearing Things Up

Professor Wolfson also clears up some common misconceptions:

* Sonic booms: People tend to think that sonic booms occur at the moment an airplane breaks through the sound barrier, and then it's over. That's not true at all. As long as an airplane is moving faster than the speed of sound, it's dragging a big shock wave behind it, creating a boom as it passes.
* What stops a car?: Brakes do not stop the car. They simply stop the wheels from turning. What stops the car is the frictional force between the wheels and the road, which is most efficient when the wheels are still rolling.
* Centrifugal force: There is no such force. The term "centrifugal force" is used to describe apparent but actually nonexistent forces one experiences in rotating frames of reference-a sort of fudge to make Newton's laws seem to apply in a situation in which they don’t apply.
* "Zero g": It's a common misconception that there's no gravity in space. Apparent weightlessness arises any time the only force acting on an object is gravity. That condition is called "free fall."

Physics in Your Life is the perfect complement to Professor Wolfson's other Teaching Company course on physics, Einstein's Relativity and the Quantum Revolution: Modern Physics for Non-Scientists. And while the two courses treat very different realms, they are united by the energy and enthusiasm of an educator whom Teaching Company customers call "brilliant," "exciting," and "one of the most dynamic and engaging professors I’ve ever had the pleasure of listening to."

Understanding Genetics: DNA, Genes, and Their Real-World Applications

Understanding Genetics: DNA, Genes, and Their Real-World Applications | 2,95 GB

We use it routinely to cure diseases, solve crimes, and reunite families. Yet we've known about it for only 60 years. And what we're continuing to learn about it every day has the potential to transform our health, our nutrition, our society, and our future. What is this powerful mystery?

It is DNA—deoxyribonucleic acid, the self-replicating material present in nearly all living organisms. Award-winning teacher, author, and cancer researcher Dr. David Sadava unlocks its mysteries in his new course, Understanding Genetics: DNA, Genes, and Their Real-World Applications. He guides us through decades of scientific discovery and the weighty implications for us, as individuals and as a society.

Genetics: The Science of Heredity

How are the traits of an organism—be it a fern or a human father—passed on to its offspring? This course outlines the history of the science of genetics and explains in detail what we have learned in recent decades about the building blocks—DNA.

Dr. Sadava, a working scientist who draws on examples from his own research, shows us how understanding genetics allows us to improve medical treatment and nutrition, vastly improving our health and quality of life.

Understanding genetics is also a critical step toward understanding our human identity. Examining our DNA—how it works and what happens when something goes wrong—enables us to see the roots of how our bodies work, why we get sick, and how traits are passed through families.

Enjoy this rare opportunity to peer over the shoulder of a working scientist; learn how he puzzles through the problems of genetics to find meaningful solutions that can save lives. Dr. Sadava shares cutting-edge research guided by his passion to help laypeople understand the meaning and importance of genetics.

Genetics' Long and Fascinating History

Our understanding of human development has certainly evolved since ancient Greek times, when Aristotle thought that the ingredients in semen were reorganized by menstrual fluid during intercourse to produce an embryo. And as late as the 17th century, Antonie Van Leeuwenhoek thought he saw tiny, fully formed babies when he looked under a microscope at sperm.

Other past civilizations, however, knew more about genetics than we might think. For example, Egyptians successfully bred the date palm 4,000 years ago to improve the quality and quantity of their fruit crop. In Asia and the Near East 3,500 years ago, horses were bred for speed in racing.

But while humans have worked to improve plant and animal characteristics for thousands of years, we've only come to truly understand what genes are made of and how they work during the past century.

Insight into a Puzzle

Understanding genetics is like sitting down to work a massive puzzle. With each piece you examine, think through, and solve, you glean a new and amazing insight into humanity. Put several pieces together, and you can treat or cure a disease, save a developing fetus from a fatal birth defect, catch a criminal, or reunite a family.

DNA, genes, proteins, amino acids, and enzymes are the vocabulary of our being—what goes on inside our bodies and how our genes are expressed. To learn this vocabulary is to be conversant in who we are and what we can become.

To help us understand the role of proteins in DNA, Professor Sadava cites the example of boiling an egg. A protein's shape is sensitive to its surroundings and can be changed by heat. When you boil an egg—made of a protein called albumin—the heat of the water changes the albumin's structure to create a completely different consistency. As Professor Sadava reminds us, "You can't unboil an egg; changes are irreversible." Next time you're making egg salad, just think—you've transformed a protein!

Dr. Sadava loves to tell tales, and the stories he uses to introduce each lecture are the highlight of the course. He weaves in history, true crime, case studies of people with life-threatening diseases, and phenomena from the natural world to make genetics come to life. Then he steadfastly supports each story with explanatory science.

Professor Sadava deftly introduces us to the puzzle that is genetics, and shows how unlocking each piece helps solve significant real-world problems that affect everyone.

Each lecture begins with a helpful story that illustrates the importance of genetics. The course explicitly outlines the connections between the science of genetics and the health-related problems that plague us in modern society, and illuminates how studying genetics can be instrumental in solving those problems.

While Understanding Genetics is a vigorous and briskly paced course, you won't need a background in biology or chemistry. You'll feel challenged, but you won't be left behind. Professor Sadava is passionate about his subject and extremely knowledgeable.

Genetics in the News

Should we allow cloning? How can we treat obesity? Why do different ethnic groups have higher rates of particular diseases than others? Countless questions of biology prompt heated discussions in the classroom, the legislature, and the courtroom. Obtaining a basic and current knowledge of how genetics works helps inform our ideas and opinions on these important issues.

Many of us are touched by diseases caused by genetic mutations or flaws—such as cystic fibrosis, diabetes, cancer, and sickle cell anemia. In the face of life-threatening, debilitating diseases, Professor Sadava gives us hope through research and discoveries made every day in the field of genetics.

He tells the story of one couple whose young son had cystic fibrosis, the most common inherited disease. Genetic testing prior to their next pregnancy enabled them to implant an embryo without the cystic fibrosis genes into the mother's uterus. The result: the couple was able to have a healthy daughter.

Only in the past few decades have scientists begun to discover and isolate the particular genes that cause certain diseases or conditions and to conduct the research that enables us to actually change genetics.

As Professor Sadava reminds us throughout the course, genetics is not destiny. How we grow and develop is strongly influenced by our environment. But understanding genetics provides us with a wealth of information that can help improve the health and quality of life for everyone.
