Today we cut the granite with diamond-cut blade as is one of the most difficult rocks to cut due to its hardness.How could the egyptians, if it was them, have achieved those shapes in the sculpture sphinx of Sénousret made of Migmatite material, which is harder than granite? What was that extraordinary tool that made this possible? This example is what disputes all the official theories of egyptology. Dozen of questions now arise. Did the egyptians really have an advance technology that was losted over time? The answer is in this movie.Lucky is to understand that in 2019, we have a chance to learn how the Great Pyramid was built, who built it, and what its hidden behind it. Let yourself go and come discover the biggest mystery of humanity, the New Great Story!

Every year, millions of high school and college students walk into their first geometry class thinking: "Circles and squares. How tough can it be?" Then they encounter the postulates, statements and theorems! But have no fear, our simple, straightforward format will help students understand and make sense of geometry.

Physics is a system of models of nature according to which all phenomena are explained in terms of matter and force. Sound confusing? It doesn't have to be! Whether you need help with high school physics, need to review for a college physics class, or you're studying for the AP Physics Exam, this physics tutorial will help you understand the basics, such as Newton's Laws, the Law of Universal Gravitation, Kepler's Law and more.

This edition of Trigonometry includes such topics as radians, the special angles, right triangles, the Pythagorean Theorem, sine, cosine, tangent, law of cosines and law of sines.

Part 2 starts off with a quick review of graphing as well as sine, cosine and tangent. From there, this video charts new territory as we dive into amplitude, curves, double-angle formulas, sum-to-product-formulas and identities. Using computer graphics and animation, the Standard Deviants illustrate these complicated concepts far better than any blackboard!

Geometry Part 2 goes into detail on perimeter, circumference and area for 2-dimensional and 3-dimensional figures. This DVD is also helpful for students who need extra help understanding the Pythagorean Theorem. Difficult concepts are made crystal clear with easy-to-follow examples and graphic presentations. With the Standard Deviants by your side, you'll be calculating the surface of a sphere or the volume of a cylinder in no time!

The last western heretic is a timely and enthralling insight into the ideas and philosophies of the New Zealander described by the BBC as “the last living heretic”. New Zealand’s very own Lloyd Geering, now 89 and still deeply involved in the debate of ideas about life and religion, and latterly, the very survival of human beings and the planet to which we belong. The documentary explores his world view in a series of controversial and richly illustrated statements, and in doing so, makes simple and comprehensible the powerful theological and cultural ideas underpinning western civilisation.

Ten years ago, Tetsuya Miyamoto had a dream to change the world through puzzles. In his classroom in Yokohama, KenKen was born. Enter a world where puzzles matter. From Tokyo to New York, from the classroom to the puzzle page to the tournament floor, Miyamoto and the Machine takes you into the brain of the inventor and the players, all while the machines of business and technology crash into artistry and humanity. Miyamoto believes each handcrafted puzzle tells a story, and if you look hard enough between the rows, columns, and cages of KenKen, you can find the story of the sensei who started a global phenomenon.

Documentary about an African-American girl who grows up to help NASA put astronauts into space and bring them home safely. She was one of the main characters in the movie, "Hidden Figures." Includes interview with Johnson.

Until recently geometry was 'cold', incapable of describing the irregular shape of a cloud, the slope of a mountain or the beauty of the human body. With fractal geometry, Benoit Mandelbrot gave us a language for our natural world. In this captivating documentary, the man himself explains this groundbreaking discovery.

Peasants that were targeted as counter-revolutionaries during the Cultural Revolution in China share their stories in this documentary by Xu Xing.

This edition includes topics such as exponential functions, common log or base 10, rules of exponents, natural log or base e, applications of exponents, rules of logs, logarithms, solving log equations and converting logs to base 10 or base e.
