4 Preface Confusion with 4th Dimension and Space, Time and Spacetime lead us to study to better understand the 3 and 4 Dimensional Spaces. After more studies of basic Geometry & Mathematics, we realized that a 4-Dimension Cube called HyperCube can be unfolded or flattened in our day-to-day 3-Dimensional Space as a 3D Cross. Since the HyperCube is bounded by eight 3- Dimensional Cubes, we invented and designed the concept of a Puzzle made of a group of eight cubes articulated by hinges and arranged in a 2 x 2 x 2 fashion that can be individually rotated in our 3-Dimension Space into a 3-Dimension Cross: We then developed proofs of concept and a number of prototypes of the 3d-Puzzle and related products of the iii

5 Introduction Introduction Introduction Scope & Theme of 4D3dPuzzles The Challenges It is NOT Complicated

6 Introduction Section 1 Scope & Theme of 4D3dPuzzles As eluded in the Preface of this Digital Book we were very curious about Spacial Dimensions greater than 3 and how geometric objects could be unfolded from a Dimensional Space to a lower Dimensional Space - for example from our familiar 3-Dimensional Space to the 2-Dimensional Flat Space; or from a 4-Dimensional Hyper Space to our day-to-day 3-Dimensional Space. This Digital Book reveals in detail what we have discovered regarding spacial geometry and how we applied its concepts to the 3d-Puzzle we invented, designed, developed and produced. The 3dPuzzles are a physical and/or virtual representation of unfolding between Spacial Dimensions. This Digital Book also explores the potential benefits of playing with the 3d-Puzzles, either in their solid format or virtual format on Mobile 4D3d Puzzles Apps. This 4D3dPuzzle Digital Book is bold, wide ranging, provocative and very engaging. It is for you whether you are young, older, have little science education or a lot. You will not want to put it down! With the assistance of Multimedia Content you will get a clear picture and understanding of what is essential to really understand Spatial Dimensions and the 3d-Puzzles. 8-Minutes YouTube Video: 4D3dPuzzles OVERVIEW If you find this topic intriguing, keep reading... 2

8 Scope & Theme of 4D3dPuzzles Are you curious about the 3-Dimension Space and the 4-Dimension Space? If this Digital Book answers some of your questions, you will be able to add and enter an important new DIMENSION in your life. This Digital Book will definitively challenge and inspire You! Are you ready to learn more? It is now up to you! 4

9 Introduction Section 2 It Is NOT Complicated This Digital Book is an easy to understand introduction to the concepts of Spatial Dimensions, the 3-Dimension Space and the 4-Dimension Space, and how these dimensional spaces relate. These concepts illustrate the idea of the 3d-Puzzles and provide the foundation of the design of such puzzles. The principles are explained in such a way that people with very little knowledge of Mathematics or Geometry will be able to understand them. For those of you who are more adventurous, the Appendices illustrate and explain in much greater details the following: Appendices: 1: Euclidian Geometry & Non-Euclidian Geometry 2: Geometry Elements & Objects 3: Spacetime 4: Tesseract - Hypercube - 8 Cell 5: Geometry of the 3d-Puzzle 6: Higher Spacial Dimensions 5

10 Basics of Geometry & Dimensions Basics of Geometry Basics of Spatial Dimension Relationships Basics of 3-Dimensional Space Basics of 4-Dimensional Space

11 Basics of Geometry & Dimensions Section 1 Basics of Spatial Dimension Relationships The Dimensions of basic Dimensional Spaces are: 0-Dimension: a Point. 1-Dimension Space: a Line (a Line is made of Points). 2-Dimension Space: a Surface (a Surface is made of Lines). 3-Dimensions Space: a Volume (a Volume is made of Surfaces). Now let s add the 4-Dimension Space: a Tesseract or HyperCube or Polychoron (a Polychoron is made of Volumes whereas a Polyhedron is made of Surfaces) 7

30 Appendix 2 Geometry Elements & Objects Geometric Object Geometry as a branch of Mathematics considers Objects such as Points, Lines, Triangles, Circles, Hexagons, Spheres, Polyhedra, Topological Spaces and Manifolds to name a few. Geometric Shapes A Geometric Shape is the geometric information which remains when location, scale, orientation and reflection are removed from the description of a Geometric Object. Moving a Geometric Shape around, enlarging it, rotating it, or reflecting it in a mirror is the same Shape as the original, and not a distinct new Shape. Dimensions In Physics and Mathematics, the Dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a Dimension of 1 because only one coordinate is needed to specify a point on it. A surface such as a plane or the surface of a cylinder or sphere has a Dimension of 2 because two coordinates are needed to specify a point on it. The inside of a cube, a cylinder or a sphere is 3-Dimensional because three coordinates are needed to locate a point within these spaces. 26

31 Geometry Elements & Objects Time A temporal Dimension is a Dimension of Time. Time is often referred to as the "4 th dimension" for this reason, but that is NOT to imply that it is a Spatial Dimension. A temporal Dimension is one way to measure physical change. It is perceived differently from the 3-Dimensional Space in that there is only one of it, and that we cannot move freely in Time but subjectively move in one direction. The best-known example of Time as a Dimension is Einstein's Special Relativity (and extended to General Relativity), which treats perceived Space and Time as components of a 4-Dimensional manifold, known as Spacetime: Science fiction texts often mention the concept of "Dimension" when referring to parallel or alternate universes or other imagined planes of existence. This is derived from the idea that to travel to parallel/alternate universes/ 27

32 Appendix 4 Tesseract - Hypercube - 8 Cell In the field of Mathematics, in Euclidean Geometry, Hypercubes in a 4-Dimensional Space are called Tesseracts. They are also called 3D-Hypercubes or 8-Cell or Octachoron or Polychoron. Projection in 3D Space of a rotating Tesseract The Spaces of the Euclidian Geometry are characterized by: In the 0-Dimension Space, a Point, is contained in, and as a result controlled, by the 1-Dimension Space, a Line. In the 1-Dimension Space, a Segment or Line, is contained in, and as a result controlled, by the 2-Dimension Space, a Polygon (a Surface). In the 2-Dimension Space, a Polygon, is contained in, and as a result controlled, by the 3-Dimension Space, a Polyhedron (a Volume). In the 3-Dimension Space, a Polyhedron, is contained in, and as a result controlled, by the 4-Dimension Space, a Polychoron (a Tesseract). In the 4-Dimension Space, a Polychoron (also called Tesseract, Hypercube, 8-cell, Regular Octachoron, Cubic Prism, and Tetracube) is contained in, and as a result controlled, by the 5-Dimension Space, a Hexadecachoron. In the higher Dimensional Spaces (5, 6, , 11, 12, etc.), it become extremely complicated. 28

33 Tesseract - Hypercube - 8 Cell Of special interest for this Digital Book is the 4D Hypercube or Tesseract According to the Oxford English Dictionary, the word Tesseract was coined and first used in 1888 by Charles Howard Hinton in his book A New Era of Thought, from the Greek τέσσερεις ακτίνες (téssereis aktines or "four rays"), referring to the four lines from each Vertex to other Vertices. The HyperCube or Tesseract is to the Cube as the Cube is to the Square; or, more formally, the Tesseract can be described as a regular convex 4-Polytope. The Tesseract is the Hypercube in, also called the 8-Cell or Octachoron. It is a regular Polytope with mutually perpendicular sides, and is therefore an Orthotope. The figure below shows how the Tesseract is made of 8 Cells (Cubes). 29

34 Appendix 5 Geometry of the 3d-Puzzle To understand the geometry of the 3d-Puzzle and the 4D3d Puzzles Apps the Geometry Nets have to be examined and reviewed. What are a Geometry Nets? In geometry the Net of a Polyhedron (a polyhedron is a solid in 3-Dimensions with flat polygonal faces, straight edges and sharp corners or vertices) is an arrangement of Edge-joined Polygons in the plane which can be folded (along Edges) to become the Faces of the Polyhedron. Cubes and Pyramids are examples of Polyhedron. In other words a Net is a Pattern that you can be cut and folded to make a model of a solid shape. A Net is a 2-Dimensional representation of a 3-Dimensional object (such as a Cube). A Net is also a 3-Dimensional representation of a 4-Dimensional object (such as a Tesseract or Hypercube). Polyhedral Nets are a useful aid to the study of Polyhedron and solid geometry in general, as they allow for physical models of polyhedron to be constructed from material such as thin cardboard or other material. Many different Nets can exist for a given polyhedron, depending on the choices of which Edges are joined and which are separated. There are distinct 11 distinct Nets of a Cube and 261 distinct Nets for a Tesseract. They will be studied in the following pages. 30

35 Geometry of the 3d-Puzzle Net of a Cube The Cube has 11 different Nets. The Net making a 2-Dimensional Cross (in red on the illustration below) is of special interest. 31
