At 1:25 on April 18, 1955, Albert Einstein, the “father of relativity,” died in Princeton University Hospital, New Jersey, at the age of 76. The writer Paderney described the scene like this: “The news of Einstein’s death immediately shocked the world. The quiet town was suddenly crowded with reporters and celebrities in the scientific world, just like the death of a prophet. The scene looks like the death of a prophet. It’s crazy.”
   Einstein made a will during his lifetime, demanding that his ashes be scattered in unknown places, no obituaries, no graves, and no monuments should be erected. Thomas Harvey, the director of the Department of Pathology at Princeton University at the time, was lucky enough to be Einstein’s post-mortem doctor although he had only one relationship with Einstein. He suddenly thought: Why not “steal” Einstein’s brain, and explore the difference between this scientist’s brain and ordinary people. Therefore, he secretly negotiated with Hans, Einstein’s eldest son, and reached an unknown agreement: take out Einstein’s brain for his own scientific research. Hans’s condition is: Harvey’s research results must not be used for personal gain and must be published in scientific journals.
Under the supervision of Otto Nathan, the executor of Einstein’s will, Harvey dissected Einstein’s body according to the procedure, examined the organs one by one, weighed them and described the appearance of the organs, and finally announced: Einstein’s The cause of death was “ruptured large aneurysm.” Soon, Einstein’s body was cremated.
   However, before Einstein’s body was cremated, Harvey didn’t put Einstein’s brain back into his skull, but put it in a container full of formaldehyde and sneaked it away.
   After “stole” Einstein’s brain as he wished, Harvey immediately quit his job and began to devote himself to studying the great scientist’s unique talents in order to uncover the mysteries.
   There is no impenetrable wall in the world. Harvey’s “stole” of Einstein’s brain was leaked soon, and public opinion was in an uproar, condemning him. Harvey defended his behavior vigorously: “Einstein is the greatest genius in the world. If he burns his brain and body together, then I will regret it for the rest of my life. I think I can’t do that.”

   Einstein’s eldest son, Hans, saw the incident and severely warned Harvey not to break his promise. In order to honor the promise to Hans and to facilitate research, Harvey took Einstein’s brain to Philadelphia, and asked a scientist friend to cut the brain into 240 pieces and save it in formalin solution. No matter where he goes, he always carries the box containing the tissue slices with him. Harvey later recalled: “After cutting off Einstein’s brain, I first injected preservatives into the cerebral arteries, and took many photos from various angles to keep it true. I also asked an artist to make a sketch, and Every part of the brain is labeled with a detailed record.”
   In the next 10 years, Harvey’s research has not yielded any results. He decided to use external forces to give Hamilton, Canada in 1989Dr. Witson from McMaster University sent a fax and asked if she would take over the research. After getting an affirmative answer, Harvey drove to Canada in person and handed Einstein’s brain tissue slices to Witson. Although Witson only obtained the parietal tissue section of Einstein’s brain, and the photos and records taken by Harvey before cutting the brain, after her careful research, it was published in the famous international academic journal “The Lancet” in 1999 A paper entitled “Albert Einstein’s Extraordinary Brain”. The article made a certain analysis of the overall shape of Einstein’s brain: the parietal and inferior regions of the left and right hemispheres of Einstein’s brain are abnormally developed, which is one centimeter thicker than the average thickness of ordinary people, which makes Einstein’s brain wider than ordinary people. About 15%, the parietal and inferior lobe area located in the upper back of the brain has formed his own unique way of thinking in terms of visual spatial cognition, mathematical thinking and sports imagination; another distinguishing feature of his brain is the lack of A kind of wrinkle in the brain of ordinary people, and the lack of this wrinkle is likely to make it easier for neurons located in the parietal and inferior lobe to establish contact with each other, thus making his thinking more active…
   Although Harvey has not achieved research results, he wants to help Einstein realize a wish. It was when Einstein was ill, he once proposed to Harvey his wish to make a journey across the United States from east to west. To help Einstein realize this long-cherished wish, Harvey drove in October 1997, accompanied by writer Patnida, and took Einstein’s brain slices from east to west, from New Jersey to California. , The whole journey exceeded 4000 kilometers, and finally completed Einstein’s last wish.
