Today (February 15, 1988) is Memorial Day for father of nanotechnology, Richard Feynman, the Nobel Prize-winning American theoretical physicist who contributed to the development of quantum electronics.

Today (February 15, 1988) is Memorial Day for the father of nanotechnology, Richard Feynman, the Nobel Prize-winning American theoretical physicist who contributed to the development of quantum electronics.

Richard Feynman was born in New York City on May 11, 1918. His father's name was Lucille, the construction of his home. Richard's mother's name was Melville Arthur Feynman, who was a sales manager. The birthplace of Richard's parents in Russia and Poland, respectively. Both of Richard's parents are Ashkenazi Jews. They are not religious. Even Richard himself openly describes himself as an atheist. Feynman spoke late. On his third birthday, he couldn't utter a word. As an adult, he began to speak some sort of English spoken in New York. Feynman was greatly influenced by his father. He encouraged him to ask questions to challenge orthodox thinking. And he was always ready to teach something new to Feynman. From his mother, he got the sense of humour he had had all his life. As a child, he had a passion for engineering. He maintained a test lab in his home. He was happy to fix the radios. When he was in grade school, he developed a home burglar alarm system.

Feynman attended Far Rockaway High School in Far Rockaway, Queens. Among them were fellow Nobel laureates Burton Richter and Baruch Samuel Blumberg. Once he started high school, Feynman was quickly promoted to high math class. An IQ test administered in a high school rated his IQ as high as 125. After many years he refused to join Mensa International. He said his IQ was too low. Physicist Steve Hsu said of the test: "This test emphasized verbal versus mathematical ability. The math/physics graduate at Princeton received high marks in the admission test. Feynman's cognitive skills may be. There were so many typos and grammatical errors when looking at parts of a notebook that Feynman had when he was an undergraduate with a bit of upside. When Feynman was 15 years old, he learned trigonometry, advanced algebra, infinite series, analytical geometry, and a diverse and integrated calculus.

Before entering college, he used his own code to experiment with math topics such as semi-derivatives. He created special logos for logarithmic, sine, cosine and touch functions. So they don't seem to be multiplying the three variables together. A member of the Arista Honor Society, she won the New York University Maths Championship in her last year of high school. His habit of direct characterism sometimes spurred conventional thinkers. Feynman applied to Columbia University. But was not accepted because of the allocation of the number of Jews allowed. Instead, he attended the Massachusetts Institute of Technology. Although he mastered math at first, he later switched to electrical engineering because he thought mathematics was too short. He noticed that he had "gone too far" and then switched to physics. After graduating, he published two papers in Physics Review. One of these was co-authored by Manuel Vallarta, "The Scattered Cosmic Rays by the Stars of a Star."

The other is John C. Gross. "Forces in Molecules" is his senior thesis, based on an idea by Slater. He was impressed enough to publish it. Today, it is called the Hellmann-Feynman theorem. In 1939, Feynman graduated with a Bachelor of Arts degree. He earned a perfect score on his graduate school admission to Princeton University in Physics. This is an unprecedented achievement. Excellent score in math, but did poorly in the history and English areas. Albert Einstein, Wolfgang Pauli and John von Neumann were among those who attended Feynman's first seminar on the classical version of the Wheeler-Feynman absorption theory. Pauli made the prediction that this theory is difficult to quantify. And one could try to use this method for gravity in general relativity, Einstein said. In his 1942 doctoral dissertation entitled "The Theory of Low Action in Quantum Mechanics," Feynman applied the principle of steady action to the problems of quantum mechanics. It was inspired by a will.

Measuring the Wheeler-Feynman absorption theory of electrodynamics, and laying the foundation for the path integral formation and Feynman diagrams. An important insight is that positrons behave like electrons moving backwards on time. One of the conditions that made Feynman pay for Princeton was that he could not marry her. Nonetheless, he was determined to marry her after he was awarded his high school sweetheart, Arlene Greenbaum, with a PhD. Despite the knowledge that she was seriously ill with tuberculosis, it was an incurable disease at the time. And he is not expected to live more than two years. On June 29, 1942, they took their boats to Staten Island. There they were married in the city office. No family or friends attended the ceremony. A pair of strangers testified.

At Caltech, Feynman explores the physics of the sophistication of supercooled liquid helium. Where helium flows show a complete lack of viscosity. With Murray Zell-Mann, Feynman developed a model of weak decay. It showed that the current in the process is a combination of the direction vector and axial currents. An example of weak decay is a neutron, an electron, a proton, and an antineutrino. After the success of quantum electrodynamics, Feynman returned to quantum gravity. By analogy with the photon with spin 1, he analyzed the effects of a free massless spin 2 field. Einstein Field derives the equation of general relativity. He is known for his research in the fields of quantum electrodynamics, the physics definition for the overlapping helium, and particle physics (particle model). Feynman partnered with Julian Schwinger and Sin-Itiro Tomonaga in the development of quantum electrodynamics. So Feynman was awarded the Nobel Peace Prize in 1965. He was a member of the team that produced the atomic bomb. He was one of the first students in quantum astronomy, to begin with. He later founded the field of quantum electrodynamics.

In 1978, Feynman sought medical treatment for abdominal pain. She was diagnosed with liposarcoma, a rare form of cancer. Surgeons removed the size of the football, which crushed a kidney and his spleen. On February 3, 1988, she was again hospitalized at UCLA Medical Center. A degenerative duodenal ulcer caused renal failure. He refused to undergo dialysis, which could last his life for several months. Nobel laureate Richard Feynman left the world on February 15, 1988, at the age of 69, to contribute to the development of quantum electrodynamics. Towards the end of her life, Feynman attempted to visit the Tuan Autonomous Soviet Socialist Republic (ASSR) in Russia. It was a nightmare overthrown by Cold War bureaucratic problems. The Soviet government's letter authorizing the trip was not received until the day after his death. His daughter, Michael, made the trip later. Her burial was in Mountain View Cemetery in Altadena, California. His last words were, "I hate dying twice. It's so boring."
