prompt.txt
Create a clear, mathematically accurate visualization of Cantor's diagonal argument proving that real numbers are uncountable. Show a hypothetical complete list of real numbers between 0 and 1, with a diagonal highlighted in red. Then show how to construct a new number by changing each digit along the diagonal, demonstrating it can't appear anywhere in the list.

Why it works

  • The proof is decomposed into the list, diagonal, transformation, and conclusion.
  • A red highlight gives the viewer an explicit reading path through the construction.
  • The final number is tied back to the claim that it cannot appear in the list.

Variables to change

  • Number of decimal rows
  • Highlight color
  • Level of explanatory annotation

Troubleshooting tips

  • Check every digit and logical statement before educational use.
  • Use fewer rows when readability matters more than visual density.
  • Ask for a separate conclusion box rather than a long paragraph.
