Скачать или смотреть He Calculated 47 Million Seconds in Two Minutes—In His Head—While Enslaved, Illiterate, and Elderly

He calculated 47 million seconds in two minutes—in his head—while enslaved, illiterate, and never having seen the inside of a classroom. His name was Thomas Fuller, though history also knew him as "Negro Tom" and the "Virginia Calculator." Born in Africa around 1710—in what is now Benin—Thomas was fourteen years old when slave traders kidnapped him and shipped him to America in 1724. He would spend the next 66 years enslaved on a Virginia farm, working the fields from sunrise to sunset, his body owned by another man. He never learned to read. He never learned to write. He never received a single day of formal education. But Thomas Fuller possessed one of the most extraordinary mathematical minds ever documented. Late in his life—when he was already in his 70s, grey-haired and worn from decades of forced labor—two antislavery campaigners named William Hartshorne and Samuel Coates heard rumors about an enslaved man with impossible calculating abilities. Skeptical but curious, they traveled to Virginia to meet him. What happened next was documented by Dr. Benjamin Rush—a Founding Father, signer of the Declaration of Independence, and prominent abolitionist—who published their account in 1789 in The American Museum. The tests they gave Thomas Fuller would challenge anyone with paper, pen, and time. He did them in his head, in minutes, while elderly and exhausted from decades of brutal labor. First challenge: "How many seconds are there in a year and a half?" Thomas closed his eyes. His lips moved slightly as he calculated. In approximately two minutes, he answered: "47,304,000." Correct. Second challenge: "How many seconds has a man lived who is 70 years, 17 days, and 12 hours old?" This calculation requires accounting for regular years, leap years, days, and hours—converting everything into seconds and adding it all together. A person with paper and pen might take fifteen minutes or more. Thomas answered in 90 seconds: "2,210,500,800." One of the gentlemen, frantically calculating with paper and pen, told Thomas he was wrong—the number was too high. Thomas replied immediately: "Stop, massa, you forget the leap year." When they corrected their written calculation to include leap years, it matched Thomas's mental calculation exactly. Third challenge: "Suppose a farmer has six sows, and each sow has six female pigs in the first year, and they all increase in the same proportion for eight years—how many sows will the farmer then have?" This is exponential growth calculation—the kind of math that requires understanding geometric progression, the mathematical concept that stumps many students even today. In ten minutes, Thomas answered: "34,588,806." Again, perfect. Dr. Rush noted that the longer time on this question was because Thomas initially misunderstood the wording, not because the calculation was harder for him. Hartshorne and Coates were astounded. Here was a man who'd never been taught mathematics, who couldn't read numbers on a page, who'd spent 66 years doing backbreaking farm labor—and he could outperform educated mathematicians using nothing but his mind. But what struck them most was something deeper. Despite being in his 70s, showing signs of age and the exhaustion of a lifetime spent enslaved, Thomas was still sharp. They suspected his abilities must have been even more remarkable in his youth, before decades of hard labor had worn him down. When Mr. Coates remarked that it was a tragedy Thomas had never received an education equal to his genius, Thomas replied with words that reveal everything about his dignity and awareness: "No, massa, it is best I had no learning, for many learned men be great fools." Think about what those words reveal. Here was a man who understood his own brilliance. Who recognized that formal education and actual intelligence are not the same thing. Who'd maintained his dignity and sense of self despite being enslaved, despite being denied every opportunity, despite living in a system designed to break him. Thomas Fuller died in 1790 at approximately 80 years old—still enslaved, still on that Virginia farm, never freed. But before he died, his story served a crucial purpose. Abolitionists like Dr. Benjamin Rush used Thomas Fuller as living proof against the racist pseudoscience that justified slavery—the vicious lies that African people were intellectually inferior, that slavery was justified because Black people supposedly couldn't handle freedom or education. Here was undeniable evidence: a man kidnapped from Africa, denied all education, worked to exhaustion for 66 years, and yet possessing mathematical abilities that rivaled or exceeded university-trained scholars. No one could challenge his genius. No one could explain it away. No one could dismiss him. Thomas Fuller's mind was a gift that slavery tried to bury—but couldn't quite hide. Today, we remember him not just for his calculations, but for what he represents: The countless brilliant minds stolen by slavery.
