What is the difference between quantum and relativity?

Relativity has two parts: General relativity and special relativity, general relativity describes gravity as a geometric property of spacetime and special relativity is the physical theory of measurement in inertial frames of reference. Now quantum mechanics, in it's wave formulation, deals with describing things on the atomic scale as a wavefunction.

What percentage of his brain did Einstein use?

we all living beings use all of (nearly all of) our brain, i.e. approx. 100% of our brain.

How many wives did Einstein have?

He had Two wives. First he married Mileva Maric who bore him three children. After divorcing her, Einstein married his own cousin, Elsa Lowenthal Einstein. Ever since the marriage between Elsa and Albert, they have been together until death.

How big was Einstein's brain?

Well the size is normal but what was outstanding is that his brain weighted 5 pounds the average brain weight 3 pounds

Children of a Lesser God 02.12.2008 by Michele Zackheim

Cults of historians, scientists, and everyday people persist in idolizing Albert Einstein. For his family, though, the name Einstein has cast a long, complicated, and difficult shadow. Today the two living grandchildren and five living great-grandchildren are weary of being hounded by Einstein worshippers and weary of trying to live up to the unprecedented achievements of their ancestor. They struggle to live private lives, well distanced from his fame, and they have succeeded: The most notable aspect of the Einstein descendants is how nearly invisible they are. Even in anonymity, though, there is no escaping the family legacy. Albert Einstein, a man of remarkable insights, was also a man of many serious flaws. His quixotic behavior and strained personal relationships loom menacingly over his descendants. Today the Einsteins are a fractured family. I recently spoke with Aude Einstein, Albert's granddaughter-in-law and the mother of all five of his great-grandchildren. I had spoken to other family members previously while researching a book about Albert's missing daughter, Lieserl, and I believed Aude was the only new source now available to me. I was petrified about calling her, and I rehearsed how I could broach the subject of her renowned ancestor without her hanging up on me. My anxiety was unfounded. As soon as I heard her welcoming voice, I thought it would be all right. Aude Ascher Einstein is in her seventies and lives in Switzerland. She is now divorced from Bernhard Einstein, the grandson of Albert. We had a friendly, lengthy telephone conversation. A few days later, though, she wrote to me and retracted her interview. "My family and I myself do not want you or anybody to write about our family. Sorry, but it would hurt and be destructive for the already precarious, fragile situation of our family. I deeply regret to have talked too much with you on the phone." I was not surprised, and in deference to her wishes, this article contains no other information from our conversation. "One cannot," Albert Einstein wrote, "expect one's children to inherit a mind." Yet his surviving family members are, to an extent, forced to define themselves against the judgments and expectations of a world that hungers for any lingering vestiges of the legendary genius. THE CHILDREN

Albert's family life was steeped in drama from the start. All three of his children were by Mileva Maric, his first wife: Lieserl, Hans Albert, and Eduard, called Tete, all born between 1902 and 1910. Lieserl, their out-of-wedlock daughter, appears to have died when she was 21 months old, most likely of scarlet fever at her mother's home in the Serbian province Vojvodina. Little is known about Lieserl; her only legacy is a complicated mystery filled with secrecy, subterfuge, and cryptic messages. Tete was admitted to the Burghölzli psychiatric hospital in Zurich when he was 38. He had been diagnosed as schizophrenic, but many people believe he was overdosed with drugs and harmed by the many "cures" that were used at the time. His father wrote to Mileva in 1932, "I am not in favor of psychiatric treatments." Less than two months later, when Tete was struggling to keep his emotional equilibrium, Albert wrote to him, "When you come to visit you must teach me about psychoanalysis; I'll try to keep a straight face." Tete and Hans Albert both tried to live up to their father's aston­ishing achievements. Hans Albert's adopted daughter, Evelyn Einstein, remembers that many of Einstein's friends and colleagues thought Tete was the one who had inherited his father's intellect. "He was definitely the genius," she says. "Next to Tete, my father was just a plodder." But Hans Albert was certainly smart enough. He studied at the Swiss Federal Institute of Technology in Zurich and became a hydraulic engineer. "Rivers don't like to be changed around," he said. "They fight back." When Hans Albert was 21, he met Frieda Knecht, a woman nine years his senior. Frieda was, like his mother, Mileva, highly intelligent and intensely opinionated. Albert and Mileva, who had been rancorously divorced for three years, were united in their opposition to the proposed marriage. There were "such significant faults of heredity in both families," Albert wrote of Mileva's and Frieda's families. "If they would never have children, I could rest easy. But the heredity of our own children is not without blemish." This was an emotionally complicated statement; Albert had always accused Mileva and her family of having "bad genes," never admitting that he and his family might too. Now he was saying that Frieda came from unhealthy stock, that she was 4 feet 11 inches tall due to dwarfism, that Frieda's mother was unbalanced (when reportedly she had an overactive thyroid). Hans Albert and Frieda married despite these protests and remained together until her death. THE GRANDCHILDREN

With Lieserl gone and Tete institutionalized, it was left to Hans Albert to pass on the Einstein genes. Bernhard Einstein, born in 1930, was Albert's first grandson; Klaus, born in 1932, was his second. In 1938 the family immigrated to America from Switzerland, settling in Clemson, South Carolina, where Hans Albert found work studying soil conservation with the U.S. Agricultural Experiment Station. But within a year tragedy struck: Klaus died of diphtheria. A number of biographers assert that his parents were adhering to the canons of Christian Science and had not sought appropriate medical attention.

Bernhard divides his time between Switzerland and California. He attended university in Zurich, then worked for the Swiss army, developing armor plating for tanks. He once recalled that when he was 25, his grandfather "talked to me for the first time ever about physics. He asked me what I know about energy, but he dropped the question immediately when he realized that I could not discuss the subject on his terms. That was the last time I saw him." Bernhard's sister, Evelyn, is the only one of Albert's descendants who still speaks openly with me. She lives in a home that is a jumble of history. When I first met her, in 1995, she was in her fifties, with cropped brown and silver hair, dressed in black pants and sandals and a bright crimson shirt. On her collar was a silver Star Trek pin. Due to illness, she could barely walk. She scooted among leaning towers of paper in an old wheelchair decorated with garishly colored plastic Star Trek gewgaws. On the day I visited, her house was a disaster. A water pipe had broken and flooded the living room; every surface was covered with piles of damp papers, and the sofa was heaped with dissolving cardboard boxes. "Don't be concerned; my house is always a bit upside down," Evelyn said, laughing. She invited me to sit on the clammy sofa. "I have to apologize for not dressing up for your visit," she continued with precise diction in a deep, lilting voice. "You see, my mother didn't teach me how to dress. And, as you can see"-she gave a sweeping gesture-"I have inherited my family's slovenly behavior. I'm not elegant." Evelyn was an infant when she was adopted by Hans Albert and Frieda. I listened in astonishment as she told me, "Since I was young, I have been told that I was really Albert Einstein's daughter." She believes that she may, in fact, be the result of an affair he had with a dancer in New York. But she does not insist: "I realized that this big, dark secret about my birth was an open book to many people. Since I have no proof, I thought that if I broached this subject to people they would think that I am crazy, a total fruitcake! So I never spoke about it." Thus Hans Albert, Evelyn's adoptive father, may possibly be her half brother, and Evelyn's brother, Bernhard, may be her nephew. Evelyn takes perverse delight in the scenario. Evelyn, born in 1941, is a highly intelligent woman, but her life as an Einstein has been awful. From the beginning, she felt closer to her mother and distant from her father. Married and then divorced, she had no children. Among a number of other jobs, she worked as a dogcatcher, a reserve policewoman, and a cult deprogrammer. After battling cancer and liver disease, she began to slide downhill. For a while she was living in her car and eating out of the trash. "I can tell you every good garbage Dumpster in the area," she said, "but I never panhandled a penny." With tenacity she pulled herself up, began to collect disability insurance, and settled down to a cloistered life, still possessing a wry sense of humor. THE GREAT-GRANDCHILDREN

"When I was 14," Evelyn said, "Bernhard took me for a ride on his motorcycle to the woods outside Zurich and told me that his wife, Aude [Albert's granddaughter-in-law], was pregnant. After Thomas was born, I remember feeling bad that my grandfather, Albert, did not live long enough to meet his first great-grandchild." I met Thomas in 1995 when I joined him and his aunt Evelyn for lunch at a fish restaurant in California. A handsome, quiet man, he seemed nervous about being with Evelyn but was very polite. In the conversation, he mentioned a "trust." Evelyn asked what it was. Thomas jumped to another subject, but I could see fire roiling in Evelyn's eyes. She later filed a complaint in California state court, alleging that her nephew and the trust's attorney had hidden a cache of letters from Albert Einstein to various family members estimated to be worth $15 million. Evelyn and her brother, Bernhard, had been named the beneficiaries of the trust. After a long legal battle and negotiations, the case was settled. Thomas, the father of three teenagers, is a physician, certified in emergency medicine and anesthesiology. He presently administers anesthesia for plastic, dental, and oral surgeons in California. Evelyn's favorite nephew seems to be Bernhard's second son, Paul Einstein, born in 1958. Since Paul was musically inclined, Bern­hard gave him Albert Einstein's violin. Today he is married and living in the south of France, where he is a composer and violinist. In 2004 Paul performed at the German Physical Society's celebration of Einstein's 125th birthday in Ulm, where Albert was born. Paul played Mozart's Sonata in E Minor, Albert's favorite piece. Eduard (Ted) Einstein, Aude and Bernhard's third son, was born in 1960. Instead of going to college, he learned masonry and construction. He now owns several furniture warehouses and a retail furniture store in the Los Angeles area, where he is married, with children. Ted once appeared in a commercial driving a new Oldsmobile, touting its worth and declaring, "You don't have to be an Einstein to figure that out." Aude and Bernhard's only daughter, Mira Einstein Yehieli, was born in 1965 and now lives in Israel with her husband, a musician, and family. Evelyn told me that the last time she saw Mira was many years ago. "She was quite pretty, musically talented." Charly Einstein, Aude and Bernhard's last child, was born in 1971. He and his family live in Switzerland, where, according to a childhood friend, he grew up loving computer games, at one point selling them at a store he owned called Einstein's World. Later he worked as a spokesman for a large hospital in Switzerland. In an online posting, great-grandson Charly addressed what it was like being related to Albert Einstein: "Sometimes it appears to me that people think that he is some kind of God. Therefore it feels like many look upon me as if I was a great-grandson of God. To be honest, that is an extremely weird and alien feeling to me." Albert Einstein was an anomaly; neither his parents nor any of his progeny showed his inspired scientific insight. Despite that-despite his grappling with his last name-Charly feels a common thread connecting him and the rest of the family to his great-grandfather. "We Einsteins do not believe in authority. We solve problems in highly unconventional ways," he has said, "in our own way."

How old would Albert Einstein be now?

In 2009,. he would be 130 years old!
had he not died in 1955, he would be 130 years old...

What is the significance of theory of relativity?

E=mc^2

Edit : That equation is part of "special relativity" not "general relativity".

What is an Einstein-Rosen bridge?

An Einstein-Rosen bridge is a hypothetical shortcut through spacetime, also called a wormhole. A wormhole is like a sort of tunnel with two ends that reach separate points in spacetime.

Was Einstein left handed?

I would also like to know the complete answer. There seems to be people that are quite sure of themselves giving both answers. I have seen a few images of him with a chalk in his right hand. As a left hander though I also write on the board with my right hand as many left handers do (you have to for cursive or the chalk bounces). I think it would be fair to assume he may have been right handed (at least at writing), even if he wasn't originally he would have most probably been forced to use his right hand in school anyway.

Hence you can't really be certain based on his writing hand alone so I had a look for him doing something very natural that he couldn't have been forced to switch hands with (in this case holding his pipe) and interestingly (to my surprise also), in all the images he seems to be using his left hand. Perhaps he was left handed but because he wrote with his right hand we get a lot of controversy.

I think whatever the case Einstein was a notoriously visual thinker, which is attributed to the right side of the brain (that left handers use and which is undoubtedly linked to the much higher percentage of left handed artists). I remember they found he had a much higher neuron density connecting the 2 halves (I'm a bit rusty though so if someone could confirm that...). I guess really, he probably got his genius from using both halves of his brain, and not specifically being left or right handed. That's what I would say anyway

Another opinion:

He was left-handed. The photos showing him writing with his right hand were laterally reversed so that it would look like he belonged to the "right", the "majority".

What is the formula of Einstein?

His formula was E=Mc2 which stood for; Energy equals mass times the speed of light squared. C=Celeratis which is Latin for "speed of light". He chose this word because he excelled in Latin in High school.

Did Nikola Tesla hate Thomas Edison?

They argued about the safest way to conduct electricity.

What's the real meaning of pi?

A mass of type confusedly mixed or unsorted., To put into a mixed and disordered condition, as type; to mix and disarrange the type of; as, to pi a form.

What school did Albert Einstein go to?

In Milan, Ohio on February 11, 1847, someone was born, who was not just an ordinary person. This someone was named Thomas Alva Edison. He would just do anything to invent something. Whatever it took he did it. When he got an idea he would not give up. The phonograph, the light bulb, the movie camera, and sewing machine are just some of his many inventions that helped change the world.

Thomas did not go to school although he was a great reader. His mom tutored him at home. When he was twelve he got his first job at the train station as a train boy selling candy and newspapers. Books were so important to him that he spent all his money on them. One day while trying to catch a train a trainman reached and grabbed him by the ears. While pulling Edison up, something cracked in his ears and right after that he began to go deaf.

In 1871, Thomas Edison married Mary Stilwell. Thomas and Mary had a couple of kids together. Thirteen years later she died, and in 1886 he married Mina Miller.

When Thomas had made enough money he wanted to buy a laboratory in Menlo Park, New Jersey. He paid a group of scientist to think of inventions and see if the inventions would work. That setup worked so well other companies did this too. Now today every company and university in the whole world has a research department, and it all began with Edison's group in Menlo Park.

He is most famous for the invention of the electric light bulb also known as the incandescent lamp {in-kandes'-ent}. He had burned himself with candles so many times, he wanted a way to see without a candle. In 1878 he began experimenting and it took him just over a year to invent a practical light bulb. Edison founded the Electric Light Company in 1878.

In his 70's he still worked sixteen hours a day, and was one of the most famous men in America. By the time he died at West Orange, New Jersey on October 18, 1931 he had created over 1000 inventions.
