Hindemburg Melao Jr. was born in Brazil, in a family with few resources, and only attended school until the 11th grade, having learned almost completely as self-taught.

​

In 1998 he was registered in the Guinness Book as the holder of the world record for longest announced checkmate in blindfold simultaneous chess games. (video)

 

Between 2006 and 2010 he developed an artificial intelligence system to trade in the Financial Market; in 2015, his friend and partner Joao A.L.J. incorporated a hedge fund to use this system and started to be registered in fund rankings (BarclayHedge, IASG and Preqin), winning 21 international high performance awards.

​

In 2007, Melao solved a problem that had been unsatisfactorily solved for 22 years, by creating "Melao index", an index to measure performance adjusted at risk that was more accurate, more predictive and conceptually better founded than the traditional indexes of William Sharpe (Nobel prize 1990) and Franco Modigliani (Nobel 1985). (video)

​

In 2003 he solved a 160+ year old problem by proposing a new formula for calculating BMI, superior to the traditional one and superior to the formula proposed in 2013 by Nick Trefethen, Chief of the Dept. of Numerical Analysis at the University of Oxford, Leslie Fox Prize(1985), FRS prize, (2005), IMA Gold Medal (2010). Trefethen's 2013 formula is an incomplete version of Melao's 2003 formula.

​

In 2000 Melao developed the first method for standardization of intelligence tests that produces scores in scale of ratio and in 2003 he applied this method in the Sigma Test norm (he also calculated new norms for Mega and Titan tests using the same method), thereby solving a problem of Psychometry that exists more than 90 years ago and was pointed by Thurstone and Gardner as a central question of Psychometry more than 45 years ago.

​

In 2002 Melao found the best solution to a problem that has existed for more than 520 years and had been attacked for more than 65 years, the Shannon Number, which was only matched in 2014 by Stefan Steinerberger, professor of mathematics at Yale University.

 

In 2015 Melao showed that the method recommended by the Nobel Prize in Economics Harry Markowitz, for portfolio optimization, has some flaws, and proposed some improvements that make this method more efficient and safer.

 

In 2021 Melao pointed out flaws in the recommendation of the 2003 Nobel Prize in Economics, Clive Granger, regarding the use of the concept of cointegration, and presented a more adequate solution to the same problem.

 

In 2022, Melao solved a problem that had been open for 16 years, in which he established a method for calculating chess ratings based on the quality of the moves. Also presented an improved version of the Elo system, applying both methods to calculate the ratings of more than 100,000 players between years 1475 and 2021, the results were published in a book, along with the description of the two methods.

 

At 9 years old Melao deduced one of the fundamentals of Fractal Geometry and at 13 he developed a method to calculate logarithms. At age 19 he developed a method for calculating factorials of decimal numbers without using Calculus. (more details)

 

Also at the age of 19 (1991) he developed an invisibility machine project, which in 1993 he inscribe in a contest of ficction Literature (although the project is consistent with Scientific Method), but did not win. In 2003 Susumu Tachi, Emeritus Professor at the University of Tokyo and guest Professor at MIT, created (independently) a simplified version of this project and built a prototype.

 

In 2020 Hindemburg presented a study showing that Jupiter's Great Red Spot cannot be 350+ years old, as was believed. The correct age is around 144 years old. (interview)

 

In 2000 Melao had a chess theoretical novelty elected one of the 10 most important in the world by the Sahovski Informator jury, the world champion Anand was one of the judges and Anand's vote was that this novelty should be the 8th most important.

 

In 2004 Baran Yonter, founder of Pars Society (IQ>180, sd=16), estimated that Melao IQ should be above 200 (sd=16).

 

In 2005 the production of the program "Fantástico", from Globo (second-largest commercial TV network in the world), made a special report on intelligence, celebrating the centenary of the creation of IQ tests, and Melao was nominated as the person with the highest IQ in Brazil, with a rarity level of 1 in 200 million. (video1, video2)

​

In 2009 Melao was nominated by Albert Frank to participate in a John Hallenborg project with people whose IQ is at the rarity level above 1 in 1 million.

 

In 2000 Melao updated and extended his “Alpha Tests” that he had created in 1991, added new questions, and created the Sigma Test.

​

In 2022 he extended the Sigma Test by creating the extended version.

 

Melao is author of more than 1700 articles on Science, Statistics, Psychometrics, Econometrics, Chess, Mathematics, Astronomy, Physics, Cognitive Science, Ethics, Philosophy of Science, History of Science, Education etc.
