Description

• 『This exploration process』is one of『the examples of the second book』
  • Using『Euclidean algorithm』to understand the『Multiple reflections』of light from the『Inner wall of the silver mirror』in the unsealed『Dewar bottle』
• Discussed the application of algebra (mathematics) in geometry (optics)
  • External light source: when it enters the『pure reflection blackbody』from the outside, the light will eventually come out from the gap. Why?
  • Internal light source: when the source is inside the『pure reflection blackbody』,light may not necessarily come out from the gap. What are the corresponding conditions?

Inplementation

1. Ideological perspective: Abstract the『optical process』in『concave mirror』into『mathematical process』
   • See the animation in file「Multiple Euclidean algorithm runs automatically in『Dewar bottle』=『pure-reflection non-absorbing notched blackbody』.pptx」
   • See the content『The origin of the circular vector』on page 8 of「2.『Illusions_of_Illustrations_·_Zodiac』.pdf」
2. Optical Expansion:『Integral Sphere with Notches』➞『Maze with Exits』
   • The same conclusion applies to『any other shape』, such as a『labyrinth-shaped cavity』
   • That is to say, the shape of a blackbody may not necessarily be spherical
     • If the light source is『inside the maze』, the light『may not be able to solve/escape the maze』
     • See the case『Maze solution』
     • If the light source is『outside the maze』, then the light『can definitely come out of the maze again』
     •

3. Mathematical Expansion:『Bivariate』to『Multivariate』linear indeterminate equation ('s Special/General solution)
   • Open the folder "cpp_codes_for_book2『Illusions_of_Illustrations_·_Zodiac』".
   • Run「12.第10个程序的改良版(2+5+8b).cpp」inside using Visual C++ 6.0, or rather,
     • using Microsoft Visual Studio C++ 6.0\Common\MSDev98\Bin\MSDEV.EXE.
     • VC6.0 Download & Setup ; Higher version of C++ is recommended, but may not be able to run this project?
