It seems to be a weird question that "Is this world real?" Why it seems to be too real? Because we see it, isn't it? We see things exist and happen as time flows. Besides seeing, we also hear, touch, smell and taste to realize our surroundings. Thus, we say "there it is" or "that is happening". Think if you had no eye, nose, ear, tongue or feeling of touch or pain; then, you would be very helpless. Why? Because you would not be able to sense anything then. Surprisingly, you won't be able to say how the world around you is. You have to have those parts of your body to realize the truth or experience the reality. Now, what are the functions of those parts? Simply they are sensitive to stimuli (such as light, smell, sound etc.) and those stimuli make nerve impulses that are carried by sensory nerves to your brain. In conclusion, what your brain experiences make an image of 'reality' and you simply believe that without confusion. ...
This is the 2nd post of my series of Dimensions. Checkout the first one in blog by searching "Dimension_001" or click this link 👉 Dimension_001 ; Now I'm going to clear some misconceptions about dimension after describing each. I'll start from 0D to 10 D. 0D :- 0 Dimension simply means 0 number of fundamental ways. You simply can make out its meaning from its name that it is "no way" actually. A 0D space is just a position without any direction to go. It is only a POINT where you cannot think about where you are and what is infront of me. Because in that space you will be stucked for eternity without moving. You cannot even fit in that because it is infinitely small and cannot be imagined. Here, some of you will ask that we have learned 0D and have learned to draw a point also. Why am I saying these ridiculous things? Actually, you have been fooled and lied in your school. You surely have learnt like this t...
Four-dimensional geometry is Euclidean geometry extended into one additional dimension . The prefix "hyper-" is usually used to refer to the four- (and higher-) dimensional analogs of three-dimensional objects, e.g., hypercube , hyperplane , hypersphere . -dimensional polyhedra are called polytopes . The four-dimensional cases of general -dimensional objects are often given special names, such as those summarized in the following table. 2-D 3-D 4-D general circle sphere glome hypersphere square cube tesseract hypercube equilateral triangle tetrahedron pentatope simplex polygon polyhedron polychoron polytope line segment plane hyperplane hyperplane square octahedron 16-cell cross polytope polygon edge face facet facet area volume content content The surface area of a hypersphere in dimensions is given by (1) where is the gamma function , giving the first few values as (2) (3) (4) (...
