• Author of the Sigma Test.
  
• The first person to solved the Combinatorial Analysis problem about the level of greatness of the number of possibilities in the Chess (June 22, 2002). This problem has been studied there more than 500 years, for many eminent mathematicians and chessplayers. The wrong solutions can be found in several books, magazines and websites, including in the New Scientist and in the book “As the mind it works”, by Steven Pinker (Ph.D. of MIT, this book wins the prizes: "Ten Best Books of the Decade / One Hundred Best Books of the Century, Amazon.com, 1999."). The eminent mathematician Stephen Wolfram, creator of the mathematics software more famous of the world (Mathematica), he also presents some incorrect solutions in his website. That problem now is part of the Sigma Test VI, question number 5.
  
• Author of a method to improve the accuracy in the stellar distance determination.
  
• Author of a method to calculate the maximum number of pieces that can be produced by applied C cuts by hyperplans in a regular object of N dimensions (including N fractal). This problem now is part of the Sigma Test VI, question number 3.
  
• Creator, in 1993, of the idea that allows to build invisibility machines, that recently (2003) was used by Susumu Tachi, that built the first prototype. Now NASA and MIT are working on invisible clothes based in my idea. (the idea is described in Sigma Test question 29)
  
• Author, in 1992, of the idea that allows to demonstrate the Last Theorem of Fermat using elementary mathematics, in 5 pages, much more economical than the method by Wiles. However I only thought about orthogonal-regular prisms. Recently (2003) the mathematician Kaida Shi used exactly my idea, but with irregular prisms, and he demonstrated the theorem. (the idea is described in Sigma Test question 24)
  
• Author of two methods to make calculations factorial of fractional, irrational and negative numbers, one developed in 2001 and another in 1992.
  
• Author of a method to improve the accuracy in the stellar parallax.

  
All of the works aforesaid were done just using mathematics of school level (ensino médio no Brasil).
