1. Introduction

Hindemburg Melão Jr. (born 15 January 1972, in São Paulo) is a Brazilian philosopher, investor, epistemologist, theologian, author, retired chess player, amateur astrophotographer, and science popularizer.^[1] Hindemburg has written over 1600 articles on science, philosophy, chess, finance, among other fields, and the book IMC na Balança ("BMI on the scale").

Hindemburg is known as a player of correspondence chess (with a rating of 2328^[2]), and of blindfold chess, where he holds the record for “longest announced mate in simultaneous blindfold chess”, with an announced checkmate in 12 moves in a simultaneous exhibition against nine boards, which was recorded in the Guinness Book.^[3][4] He has also gathered a collection of blindfold chess games from many players from different epochs.^[5]

He is also a chess analyst and theoretician, having twice received the distinction of having theoretical innovations considered among the best by the jury of Šahovski Informator.^{[6][7][8][9][10][11][12]} Hindemburg is interested in the subject of human intelligence, and is the founder of Sigma Society, Brazil's former most selective high IQ society.^[13][14]

2. BMI

In his 2008 book, IMC na Balança, Hindemburg proposed a correction in the formula used for the body mass index:^[15]

${\displaystyle BMI=\frac{1.67m}{h^3}}$

where m is the mass and h the height of a person, in the International System of Units.

In 2013 Nick Trefethen proposed a new different formula to calculate the BMI of a person:^[16][17]

${\displaystyle \text{BMI}=1.3\times \frac{\text{weight}}{{\text{height}}^{2.5}}}$

(International System of Units)

3. Saturno V

His studies on the financial market have resulted in the creation of Saturno V, an artificial intelligence software that continuously analyzes the prices of financial instruments in search for morphological patterns. It was presented at Shark Tank.^[18]

4. Philosophical Views

^[19][20]*On freedom: "People should be free to do whatever they want, within limits that do not harm other people."

• On logic: "Our reason is extremely weak, so it inhibits the development of bold ideas whenever these ideas do not rely on the "crutches" provided by our logic. But if we throw away those crutches and let ourselves be guided by the wings of the imagination, then we can transcend and see beyond horizons."
• On education: "I think it should be mandatory to provide meals and decent living conditions and education to all people, especially children, and I believe that schools should offer optional classes in all disciplines, as well as guidance so that children can compose curriculum more compatible with their natural aptitudes and personal preferences."
