It’s time to meet a man who has an awesome mind He can calculate faster than calculator Jaime Garcia looks like a normal man but his brain is unique in the planet This Colombian can do mentally complex mathematical functions, that are almost imposible to solve without the use of a calculator I started to practise 48 years ago I was 8 years old when I learned to use the Abacus, in my town Malaga – Colombia from there came the challenge to solve elementary functions After that came complex functions like square roots, logarithms, trigonometric functions. when I got the secondary, I didn’t know what that was for I studied it and I made my own method. He is called “The Human Calculator” and I want to know if he has a knack that makes him being unique JAIME GARCIA SERRANO “THE HUMAN CALCULATOR” Jaime Garcia has got 5 Guinness Records He extracted the 13th root of a 100 digit number in less than a second a group of mathematicians are waiting for us to do the first test at Palermo University how could we start with the test? we can start with square roots if you agree Yes I agree, let’s start The first one: Square root of 4.256 65.2 That’s right Well, can I ask you the square root of 789.654 888.6 That’s perfect! The test has just started, but the “Human Calculator” is demonstrating what he can do however, his capacity is much better than I was expecting SUPERHUMANS My name is Tusam, I’m looking for Superhumans in this Continent Now, I must meet a man whose mind is faster than calculator a group of mathematicians are asking him to calculate functions that are getting more complex to find out the level he could reach Mathematicians are surprised because his speed to calculate Let’s see when they ask him for more difficult functions what to do next? We could calculate ten base Logarithms if you agree Ok, let’s do it, too! What is a Logarithm? A Logarithm is the power to which a number must be raised in order to get some other number. For example, the base ten Logarithm of 100 is 2, because ten raised to the power of two is 100 but if I want to know ten raised to the power of “x” is 8. What’s “x”? I don’t know! I do need a calculator, Don’t I? Log of 12.586.200 7,099 Yes! 7,1 ehh, can I ask you Log of 7.896.321.456 9,897 Perfect! The functions are even getting more difficult but Jaime is being faster Well Jaime, can I ask you the Sine of 1.045? Thousand… forty five ehh… 0,573576436351046521 It’s correct! Well, now can I ask you Cosine of 78.541 0,484809620246337821415 Yes! perfect, that’s right! Mathematicians can’t believe Jaime’s speed and accuracy Well, to finish the test, what mathematical functions you think we could ask him Well, what about to calculate Factorials? I don’t know if you’re happy to do it Yes, It’s fine! The factorial function means to multiply a series of descending natural numbers 4 factorial is 1 × 2 × 3 × 4=24 5 factorial is 1 × 2 × 3 × 4 × 5 50 factorial is 1 × 2 × 3 × 4 × 5 × 6 till 50 so the first factorial to calculate…27 factorial 1.088886945 raised to the power of 28 Perfect!! Well Jaime, can I ask you 31 factorial 8.222838654 raised to the power of 33 Correct!! Have you ever tried to do this kind of functions? without the use of a computer or a calculator No, I haven’t and I don’t know anyone who have done it as fast as him Have you ever met anyone like Jaime? No, no one. Neither do I. It’s awesome, I’d like to know his secret and his methods and how he answer so much numbers. I know a guy that can multiple bigger numbers than me but nobody who can calculate Sine, Cosine, Inverse…It’s not the same Mathematicians don’t know what to say It’s time to make a medical test to Jaime, we want to find out if his brain works different than any other person A group of medical experts are waiting for us, They are going to make to Jaime a Functional Magnetic Resonance imaging, or fMRI. This is a technique for measuring brain activity It can be used to produce activation maps showing which parts of Jaime’s brain are involved in a complex mental process It means that when a brain area is more active, it consumes more oxygen and to meet this increased demand, blood flow increases to the active area Then we’ll get a pattern of signals on the brain. If the blood is more oxygenated the signal is slightly stronger Ok, Jaime, do you agree? Yes, I do. Doctors, are you ready? We’re ready! Let’s start, then while Jaime is getting the tomogragh, Doctors are preparing the test Jaime will be asked to do some calculus while the tomogragh checks his brain Everything is ready to start the test Jaime, can you hear me? Yes, I can. Well, you’re going to calculate square roots, starting with the number 32.550 decreasing by 100 units each square root when we say “now”, you will start to calculate when we say “stop” you’ll have blank mind, do you understand? Understood. “Now” to every mathematical calculation, Jaime’s brain cortex reacts. the test is quite detailed now we’ll see the medical test results Doctors, what are the results of the test? We can see that Jaime uses his left cerebral hemisphere there is no much reaction in the right side but we see that Jaime uses wide areas of his cerebral cortex, both the front and parietal lobe. these areas are used by everybody, but Jaime does it with much more breadth and intensity Jaime gets a hyperactivity in his brain when he does mental processes another interesting thing on the test result is that we don’t see any anxiety component I mean that Jaime doesn’t get nervous when he is calculating He never shows any fear or doubt, he doesn’t think he will fail. Have you ever seen anybody like Jaime? It’s not common, is it, Dr? We hadn’t ever seen so much cortical activation like Jaime’s case, while he is calculating. “The Human Calculator” has surprised the Mathematicians and Doctors because his capacity to calculate. However, I want to find out how far ge can get. so that, I have asked a group of people to do one more test we’ll do a different kind of test Jaime says he can determine any day of the week in the Gregorian calendar Let’s start with you, ok? Please, tell me the year 1.973 The month September and the day? 13th Jaime: Thursday Thursday, that’s right! Please, what year? 8 month? March what day? 18th Jaime: Sunday 18th, Sunday….correct! Jaime gets the answer before I finish to type on the computer but I want the test gets more complex asking him about thousands of years in the future Miss, tell him any year, but with millions 7.531.402 what month? September What day? 19th Jaime: Sunday He has answered all the dates correctly in the past, in the future even in years with millions I’d like to do one more test can I ask you about mnemotecnia? Yes, sure! Well, I want you to tell him some numbers and Jaime will try to memorise them is that right? Indeed! do we start with it? Yes, let’s do it. 13 11 85 while they are telling the numbers to Jaime I’m typing them on the screen that is behind him Jaime can not see the numbers no way 92 28 Jaime looks very concentrate as much numbers more difficult 35 Last two digits, Please! 88 We’ve got a number of 52 digits Jaime, could you tell us the number? Yes! 1 3 1 1 8 5 9 9 2 2 2 6 3 eeh, 5 2 8 6 1 1 6 8 8 2 7 8 0 1 4 3 3 9 2 2 2 2 0 6 4 5 7 1 9 7 3 3 0 1 0 1 8 8 and 8 Jaime has overcome all tests in an incredible way to perform complex mathematical calculations Jaime uses much higher extension and intensity of his brain than the rest of the population that allows him to achieve levels of accuracy and speed never seen he has shown that he is capable of performing all calculations that has been asked He is a real Superhuman!!
