00:00Have you ever wondered about the mind that shook the very foundations of physics?
00:04Albert Einstein, born on March 14, 1879, in Ulm, Germany, was that mind.
00:11He revolutionized how we perceive the universe. Einstein is famous for his theories of relativity,
00:18which transformed our understanding of space, time, and gravity. His most celebrated equation,
00:24E equals mix squared, established the relationship between mass and energy, cementing his place in
00:31history. In 1905, sometimes called his, Miracle Year, Einstein published four revolutionary papers.
00:39These included groundbreaking insights into the photoelectric effect and Brownian motion.
00:45Each paper reshaped scientific thought and laid the groundwork for modern physics.
00:50By 1915, Einstein introduced the general theory of relativity.
00:56This theory explained how mass curves spacetime, revolutionizing our comprehension of gravity.
01:02It offered new insights into the cosmos, especially during the 1919 solar eclipse when
01:08his predictions were confirmed. Einstein's journey was not just intellectual.
01:13He faced immense challenges, including fleeing Nazi Germany for the US in 1933 due to his Jewish
01:20heritage. Settling in Princeton, he continued his research at the Institute for Advanced Study.
01:27Throughout his life, Einstein's commitment to peace was unwavering.
01:32Despite advocating for nuclear weapons research during World War II, he later expressed regret,
01:38emphasizing that war should be avoided at all costs. Einstein's personal life was as complex as his
01:45scientific pursuits. He married twice, had three children, and frequently wrote heartfelt letters
01:51to family and friends, showcasing his emotional depth. His legacy transcends science.
01:58Einstein advocated for civil rights in America, condemning racism and supporting African-American
02:04equality. He was a prominent voice in humanitarian efforts and an inspiration globally. In his later
02:11years, Einstein's thoughts remained deeply philosophical. He considered himself an agnostic,
02:18believing in a pantheistic god while emphasizing humanity's need for ethical culture over religious dogma.
02:25Albert Einstein passed away on April 18, 1955, leaving a profound legacy. His work not only explained the
02:33laws of the universe but also inspired generations of scientists to dream big and question reality.
02:40If you want to dive deeper into Einstein's life and theories, subscribe to our channel for more
02:45enlightening content. The Childhood and Education of Albert Einstein
02:49Einstein's parents were secular, middle-class Jews. His father, Hermann Einstein, was originally a
02:57featherbed salesman and later ran an electrochemical factory with moderate success.
03:02His mother, the former Pauline Koch, ran the family household. He had one sister, Maria, who went by the
03:10name Maha, born two years after Albert. Einstein would write that two wonders deeply affected his early
03:17years. The first was his encounter with a compass at age five. He was mystified that invisible forces could
03:25deflect the needle. This would lead to a lifelong fascination with invisible forces.
03:32The second wonder came at age 12 when he discovered a book of geometry, which he devoured, calling it his
03:38sacred little geometry book. Einstein became deeply religious at age 12, even composing several songs in
03:45praise of God and chanting religious songs on the way to school. This began to change, however, after he read
03:52science books that contradicted his religious beliefs. This challenge to established authority left a deep
03:59and lasting impression. At the Louisville Gymnasium, Einstein often felt out of place and victimized by a
04:06Prussian-style educational system that seemed to stifle originality and creativity. One teacher even told
04:13him that he would never amount to anything. Yet another important influence on Einstein was a young medical student,
04:19Max Talmud, later Max Talmy, who often had dinner at the Einstein home. Talmud became an informal tutor,
04:28introducing Einstein to higher mathematics and philosophy. A pivotal turning point occurred when
04:34Einstein was 16 years old. Talmud had earlier introduced him to a children's science series by Aaron Bernstein,
04:41Nature Wissenschaftliche Volksbücher, 1867-68, popular books on physical science, in which the author
04:50imagined writing alongside electricity that was traveling inside a telegraph wire. Einstein then
04:56asked himself the question that would dominate his thinking for the next 10 years, what would a light
05:02beam look like if you could run alongside it? If light were a wave, then the light beam should appear
05:07stationary, like a frozen wave. Even as a child, though, he knew that stationary light waves had never been
05:14seen, so there was a paradox. Einstein also wrote his first scientific paper, at that time, the
05:22investigation of the state of ether in magnetic fields. Einstein's education was disrupted by his
05:28father's repeated failures at business. In 1894, after his company failed to get an important contract to
05:35electrify the city of Munich, Hermann Einstein moved to Milan to work with a relative. Einstein was left at
05:42a boarding house in Munich and expected to finish his education. Alone, miserable, and repelled by the
05:49looming prospect of military duty when he turned 16, Einstein ran away six months later and landed on the
05:56doorstep of his surprised parents. His parents realized the enormous problems that he faced as a school
06:02dropout and draft dodger with no employable skills. His prospects did not look promising.
06:09Fortunately, Einstein could apply to the Swiss Federal Polytechnic School in Zurich without a high
06:15school diploma, as long as he passed its difficult entrance exams. The school later became known as the
06:21Swiss Federal Institute of Technology after gaining university status. His marks showed that he excelled in
06:28mathematics and physics, but he failed at French, chemistry, and biology. Because of his exceptional
06:35math scores, he was allowed into the Polytechnic on the condition that he first finish his formal
06:40schooling. He went to a special high school run by Joost Wintler in Aarau, Switzerland, and graduated in
06:471896. He also renounced his German citizenship at that time. He was stateless until 1901, when he was granted
06:56Swiss citizenship. He became lifelong friends with the Wintler family, with whom he had been boarding.
07:04Wintler's daughter, Marie, was Einstein's first love. Einstein's sister, Maha, would eventually marry Wintler's
07:11son Paul, and his close friend Michelle Besso would marry their eldest daughter, Anna. Einstein would
07:18recall that his years in Zurich were some of the happiest years of his life. He met many students
07:23who would become loyal friends, such as Marcel Grossman, a mathematician, and Besso, with whom he
07:29enjoyed lengthy conversations about space and time. He also met his future wife, Maleva Maric, a fellow
07:37physics student from Serbia, from graduation to the miracle year of the scientific theories of Albert
07:43Einstein. After graduation in 1900, Einstein faced one of the greatest crises in his life. Because he
07:51studied advanced subjects on his own, he often cut classes. This earned him the animosity of some
07:57professors, especially Heinrich Weber. Unfortunately, Einstein asked Weber for a letter of recommendation.
08:04Einstein was subsequently turned down for every academic position that he applied for. He later
08:12wrote, I would have found a job long ago if Weber had not played a dishonest game with me. Meanwhile,
08:18Einstein's relationship with Maric deepened, but his parents vehemently opposed the relationship.
08:24His mother especially objected to her Serbian background, Maric's family was Eastern Orthodox Christian.
08:30Einstein defied his parents, however, and in January 1902, he and Maric even had a child,
08:38Lieserl, whose fate is unknown. It is commonly thought that she died of scarlet fever or was given
08:44up for adoption. In 1902, Einstein reached perhaps the lowest point in his life. He could not marry Maric
08:52and support a family without a job, and his father's business went bankrupt. Desperate and unemployed,
08:59Einstein took lowly jobs tutoring children, but he was fired from even these jobs.
09:05The turning point came later that year, when the father of his lifelong friend Marcel Grossman was
09:10able to recommend him for a position as a clerk in the Swiss patent office in Bern. About then,
09:17Einstein's father became seriously ill and, just before he died, gave his blessing for his son to marry Maric.
09:23For years, Einstein would experience enormous sadness remembering that his father had died,
09:30thinking him a failure. With a small but steady income for the first time, Einstein felt confident
09:36enough to marry Maric, which he did on January 6, 1903. Their children, Hans Albert and Eduard,
09:44were born in Bern in 1904 and 1910, respectively. In hindsight, Einstein's job at the patent office
09:52was a blessing. He would quickly finish analyzing patent applications, leaving him time to daydream
09:58about the vision that had obsessed him since he was 16. What would happen if you raced alongside a
10:04light beam? While at the Polytechnic School, he had studied Maxwell's equations, which described the
10:10nature of light, and discovered a fact unknown to James Clerk Maxwell himself, namely, that the speed
10:17of light remains the same no matter how fast one moves. This violates Newton's laws of motion, however,
10:24because there is no absolute velocity in Isaac Newton's theory. This insight led Einstein to formulate
10:30the principle of relativity. The speed of light is a constant in any inertial frame, constantly moving
10:37frame. During 1905, often called Einstein's, miracle year, he published four papers in the
10:43Analon der Physik, each of which would alter the course of modern physics. 1. Über einen
10:49der Zeugung und Verwandlung der Lichts betreffenden heuristischen Gesichtspunkt, on a heuristic viewpoint
10:56concerning the production and transformation of light, in which Einstein applied the quantum theory
11:01to light in order to explain the photoelectric effect. If light occurs in tiny packets, later
11:08called photons, then it should knock out electrons in a metal in a precise way.
11:122. Über die von der Molekulärkinetischen Theorie der Warme geforderte bewaging von in Ruhenden
11:19Flüssigkeit und Suspendiärten Teilchen, on the movement of small particles suspended in stationary
11:25liquids required by the molecular kinetic theory of heat, in which Einstein offered the first
11:31experimental proof of the existence of atoms. By analyzing the motion of tiny particles
11:37suspended in still water, called Brownian motion, he could calculate the size of the jostling
11:42atoms and Avogadro's number, see Avogadro's Law. 3. Zer-Electrodynamic Bewerder Korper,
11:49on the electrodynamics of moving bodies, in which Einstein laid out the mathematical theory
11:55of special relativity. 4. First die Trigheit eines Korpers von Sinem Energieinhalt
12:01abongig, does the inertia of a body depend upon its energy content, submitted almost as an
12:07afterthought, which showed that relativity theory led to the equation E equals m². This provided the
12:13first mechanism to explain the sun's energy source and other stars. Einstein also submitted a paper in
12:201905 for his doctorate. Other scientists, especially Henri Poincaré and Hendrik Lorentz,
12:27had pieces of the theory of special relativity, but Einstein was the first to assemble the whole theory
12:33and to realize that it was a universal law of nature, not a curious figment of motion in the ether,
12:39as Poincaré and Lorentz had thought. In one private letter to Mileva, Einstein referred to,
12:45our theory, which has led some to speculate that she was a co-founder of relativity theory.
12:52However, Mileva abandoned physics after failing her graduate exams twice,
12:57and there is no record of her involvement in developing relativity.
13:00In his 1905 paper, Einstein only credits his conversations with Besso in developing relativity.
13:08In the 19th century, there were two pillars of physics, Newton's laws of motion and Maxwell's theory
13:14of light. Einstein was alone in realizing that they were in contradiction and that one of them must
13:20fall, general relativity and the teaching career of Albert Einstein. At first Einstein's 1905 papers
13:27were ignored by the physics community. This began to change after he received the attention of just one
13:34physicist, perhaps the most influential physicist of his generation, Max Planck, the founder of the
13:40quantum theory. Soon, owing to Planck's laudatory comments and to experiments that gradually confirmed
13:47his theories, Einstein was invited to lecture at international meetings, such as the Solvay conferences,
13:53and he rose rapidly in the academic world. He was offered a series of positions at increasingly
13:59prestigious institutions, including the University of Zurich, the University of Prague, the Swiss Federal
14:05Institute of Technology, and finally the University of Berlin, where he served as director of the Kaiser
14:11Wilhelm Institute for Physics from 1913 to 1933. Although the opening of the institute was delayed until
14:191917. Even as his fame spread, Einstein's marriage was falling apart. He was constantly on the road,
14:28speaking at international conferences, and lost in contemplation of relativity. The couple argued
14:34frequently about their children and their meager finances. Convinced that his marriage was doomed,
14:40Einstein began an affair with a cousin, Elsa Lowenthal, whom he later married. Elsa was a first cousin on his
14:48mother's side and a second cousin on his father's side. When he finally divorced Mileva in 1919, he agreed
14:54to give her the money he might receive if he ever won a Nobel Prize. One of the deep thoughts that consumed
15:01Einstein from 1905 to 1915 was a crucial flaw in his own theory, it made no mention of gravitation or
15:08acceleration. His friend Paul Ehrenfest had noticed a curious fact. If a disk is spinning, its rim travels
15:16faster than its center, and hence, by special relativity, meter sticks placed on its circumference
15:22should shrink. This meant that Euclidean plane geometry must fail for the disk. For the next 10
15:29years, Einstein would be absorbed with formulating a theory of gravity in terms of the curvature of
15:35space-time. To Einstein, Newton's gravitational force was actually a by-product of a deeper reality,
15:42the bending of the fabric of space and time. In November 1915, Einstein finally completed the
15:49general theory of relativity, which he considered to be his masterpiece. In the summer of 1915,
15:56Einstein had given six two-hour lectures at the University of Göttingen that thoroughly explained
16:01an incomplete version of general relativity that lacked a few necessary mathematical details.
16:07Much to Einstein's consternation, the mathematician David Hilbert, who had organized the lectures at his
16:13university and had been corresponding with Einstein, then completed these details and submitted a paper in
16:19November on general relativity just five days before Einstein, as if the theory were his own.
16:26Later they patched up their differences and remained friends. Einstein would write to Hilbert,
16:31I struggled against a resulting sense of bitterness, and I did so with complete success.
16:37I once more think of you in unclouded friendship and would ask you to try to do likewise toward me.
16:43Today physicists refer to the action from which the equations are derived as the Einstein-Hilbert action,
16:48but the theory itself is attributed solely to Einstein. Einstein was convinced that general
16:54relativity was correct because of its mathematical beauty and because it accurately predicted the
17:00precession of the perihelion of Mercury's orbit around the Sun. See Mercury. Mercury in tests of
17:06relativity. His theory also predicted a measurable deflection of light around the Sun. As a consequence,
17:13he even offered to help fund an expedition to measure the deflection of starlight during an eclipse of
17:19the Sun. World-renowned and a Nobel Prize winner. Einstein's work was interrupted by World War I and a
17:26lifelong pacifist. He was one of only four intellectuals in Germany to sign a manifesto opposing
17:32Germany's entry into war. Disgusted, he called nationalism, the measles of mankind. He would write,
17:39at such a time as this, one realizes what a sorry species of animal one belongs to.
17:45In the chaos unleashed after the war, in November 1918, radical students seized control of the
17:51University of Berlin and held the rector of the college and several professors hostage.
17:57Many feared that calling in the police to release the officials would result in a tragic confrontation.
18:03Einstein, because he was respected by both students and faculty,
18:07was the logical candidate to mediate this crisis.
18:11Together with Max Born, Einstein brokered a compromise that resolved it.
18:16After the war, two expeditions were sent to test Einstein's prediction of deflected starlight near the
18:22Sun. One set sail for the island of Principe, off the coast of West Africa, and the other to
18:28Sabral in northern Brazil in order to observe the solar eclipse of May 29, 1919.
18:34On November 6, the results were announced in London at a joint meeting of the Royal Society
18:40and the Royal Astronomical Society.
18:43Nobel laureate J.J. Thompson, president of the Royal Society, stated,
18:48The headline of the Times of London read,
18:50Revolution in Science, New Theory of the Universe, Newton's Ideas Overthrown,
18:56Momentous Pronouncement, Space, Warp.
18:58Almost immediately, Einstein became a world-renowned physicist, the successor to Isaac Newton.
19:06Invitations came pouring in for him to speak around the world.
19:10In 1921, Einstein began the first of several world tours, visiting the United States, England,
19:17Japan, and France. Everywhere he went, the crowds numbered in the thousands.
19:22On route from Japan, he received word that he had received the Nobel Prize for physics,
19:29but for the photoelectric effect rather than for his relativity theories.
19:33During his acceptance speech, Einstein startled the audience by speaking about relativity instead
19:39of the photoelectric effect. Einstein also launched the new science of cosmology.
19:45His equations predicted that the universe is dynamic, expanding, or contracting.
19:50This contradicted the prevailing view that the universe was static, so he reluctantly introduced
19:56a cosmological term to stabilize his model of the universe.
20:01In 1929, astronomer Edwin Hubble found that the universe was indeed expanding, thereby confirming
20:07Einstein's earlier work.
20:09In 1930, in a visit to the Mount Wilson Observatory near Los Angeles, Einstein met with Hubble and declared
20:17the cosmological constant to be his greatest blunder. Recent satellite data, however, have shown that
20:23the cosmological constant is probably not zero but dominates the matter-energy content of the entire
20:29universe. Einstein's blunder apparently determines the ultimate fate of the universe.
20:36During that same visit to California, Einstein was asked to appear alongside the comic actor Charlie
20:42Chaplin during the Hollywood debut of the film City Lights.
20:46When they were mobbed by thousands, Chaplin remarked,
20:49The people applaud me because everybody understands me, and they applaud you because no one understands
20:55you. Einstein asked Chaplin, What does it all mean?
20:59Chaplin replied, Nothing.
21:01Einstein also began correspondences with other influential thinkers during this period.
21:06He corresponded with Sigmund Freud, both of them had sons with mental problems, on whether war
21:12was intrinsic to humanity. He discussed with the Indian mystic Rabindranath Tagore whether
21:18consciousness can affect existence. One journalist remarked, It was interesting to see them together,
21:25Tagore, the poet with the head of a thinker, and Einstein, the thinker with the head of a poet.
21:31It seemed to an observer as though two planets were engaged in a chat.
21:34Einstein also clarified his religious views, stating that he believed there was an old one,
21:41who was the ultimate lawgiver. He wrote that he did not believe in a personal god that intervened
21:47in human affairs but instead believed in the god of the 17th century Dutch Jewish philosopher
21:52Benedict de Spinoza, the god of harmony and beauty. His task, he believed, was to formulate a
21:59master theory that would allow him to read the mind of God. He would write, I'm not an atheist,
22:04and I don't think I can call myself a pantheist. We are in the position of a little child entering
22:11a huge library filled with books in many different languages. Increased professional
22:15isolation and death. Although Einstein continued to pioneer many key developments in general
22:21relativity, such as wormholes, higher dimensions, the possibility of time travel, the existence of
22:28black holes, and the creation of the universe. He became increasingly isolated from the rest of the
22:33physics community. Due to the enormous advances made by quantum theory in uncovering the secrets
22:39of atoms and molecules, most physicists worked on quantum theory, not relativity. Einstein engaged in
22:47a series of historic private debates with Niels Bohr, creator of the Bohr model of the atom.
22:53Through a series of sophisticated, thought experiments, Einstein attempted to find logical inconsistencies
22:59in quantum theory, particularly its lack of a deterministic mechanism. Einstein often said that,
23:06God does not play dice with the universe. In 1935, Einstein's most famous attack on quantum theory
23:13led to the EPR, Einstein-Podolsky-Rosen, thought experiment. According to quantum theory, under certain
23:21circumstances, two electrons separated by enormous distances would have their properties linked,
23:27as if they were an umbilical cord. Under these circumstances, if the properties of the first
23:33electron were measured, the state of the second would be known instantaneously, at a speed greater
23:38than the speed of light. This conclusion, according to Einstein, clearly violated relativity.
23:45Experiments conducted since then have confirmed that quantum theory, not Einstein, was right about the
23:51EPR experiment. Essentially, what Einstein had shown was that quantum mechanics is non-local,
23:58that is, that random information can travel faster than light. This does not violate relativity,
24:04because information is random and therefore useless. The other reason for Einstein's growing
24:09estrangement from his colleagues was his obsession, beginning in 1925, with discovering a unified field
24:16theory. A comprehensive theory that would unify the forces of the universe, and thus the laws of physics,
24:23within a single framework. In his later years, he stopped opposing quantum theory and tried to
24:29incorporate it, along with light and gravity, into a broader unified field theory. Little by little,
24:36Einstein settled into his old ways. He rarely traveled far, limiting himself to long walks around
24:43Princeton with those close to him, with whom he engaged in deep conversations about politics,
24:48religion, physics, and his unified field theory. In 1950, he published an article on his theory in
24:56Scientific American, but because it ignored the still mysterious strong nuclear force, it was
25:01necessarily incomplete. When he died five years later from an aortic aneurysm, it remained unfinished.
25:08Nazi backlash and coming to America. Inevitably, Einstein's fame and the great success of his
25:15theories created a backlash. The rising Nazi movement found a convenient target in relativity,
25:21branding it, Jewish physics, and sponsoring conferences and book burnings to denounce Einstein and his
25:27theories. The Nazis enlisted other physicists, including Nobel laureates Philip Leonard and Johannes
25:34Stark to denounce Einstein. One Hundred Authors Against Einstein was published in 1931.
25:42When asked to comment on this denunciation of relativity by so many scientists,
25:46Einstein replied that to defeat relativity, one did not need the word of 100 scientists, just one fact.
25:54In December 1932, Einstein decided to leave Germany forever, he would never go back.
26:01It became obvious to Einstein that his life was in danger. A Nazi organization published a magazine
26:08with Einstein's picture and the caption, not yet hanged, on the cover. There was even a price on his
26:14head. So great was the threat that Einstein split with his pacifist friends and said that it was justified
26:20to defend yourself with arms against Nazi aggression. To Einstein, pacifism was not an absolute concept,
26:28but one that had to be re-examined depending on the magnitude of the threat. Einstein settled at
26:33the newly formed Institute for Advanced Study at Princeton, New Jersey, which soon became a mecca for
26:39physicists from around the world. Newspaper articles declared that the Pope of Physics had left Germany
26:46and that Princeton had become the new Vatican, personal sorrow, World War II, and the atomic bomb.
26:53The 1930s were hard years for Einstein. His son Eduard was diagnosed with schizophrenia and suffered a
27:00mental breakdown in 1930. Eduard would be institutionalized for the rest of his life.
27:07Einstein's close friend, physicist Paul Ehrenfest, who helped in the development of general relativity,
27:13committed suicide in 1933. And Einstein's beloved wife, Elsa, died in 1936.
27:21The true story of Oppenheimer and the atomic bomb. Robert Oppenheimer became involved in nuclear
27:30research in 1941. His biopic, Oppenheimer, was released in 2023. To his horror, during the late 1930s,
27:41physicists began seriously to consider whether his equation E equals mc squared might make an atomic
27:46bomb possible. In 1920, Einstein himself had considered but eventually dismissed the possibility.
27:54However, he left it open if a method could be found to magnify the power of the atom.
28:00Then, in 1938-39, Otto Hahn, Fritz Strassmann, Lise Meitner, and Otto Frisch showed that the
28:08splitting of the uranium atom could unleash vast amounts of energy. The news electrified the physics
28:14community. In July 1939, physicist Leo Szilard convinced Einstein that he should send a letter
28:21to U.S. President Franklin D. Roosevelt urging him to develop an atomic bomb. With Einstein's guidance,
28:29Szilard drafted a letter on August 2 that Einstein signed, and the document was delivered to Roosevelt
28:34by one of his economic advisers, Alexander Sachs, on October 11. Roosevelt wrote back on October 19,
28:42informing Einstein that he had organized the uranium committee to study the issue.
28:47Einstein was granted permanent residency in the United States in 1935 and became an American citizen
28:54in 1940, although he chose to retain his Swiss citizenship. During the war, Einstein's colleagues
29:01were asked to journey to the desert town of Los Alamos, New Mexico, to develop the first atomic bomb for
29:07the Manhattan Project. Einstein, the man whose equation had set the whole effort into motion,
29:13was never asked to participate. Voluminous Declassified Federal Bureau of Investigation
29:19files, numbering several thousand, reveal the reason. The U.S. government feared Einstein's
29:26lifelong association with peace and socialist organizations. FBI Director J. Edgar Hoover went
29:33so far as to recommend that Einstein be kept out of America by the Alien Exclusion Act, but he was
29:39overruled by the U.S. State Department. Instead, during the war, Einstein was asked to help the U.S. Navy
29:46evaluate designs for future weapons systems. Einstein also helped the war effort by auctioning off
29:53priceless personal manuscripts. In particular, a handwritten copy of his 1905 paper on special
29:59relativity was sold for $6.5 million. It is now located in the Library of Congress. Einstein was
30:07on vacation when he heard the news that an atomic bomb had been dropped on Japan. Almost immediately,
30:14he was part of an international effort to try to bring the atomic bomb under control,
30:19forming the Emergency Committee of Atomic Scientists. Albert Einstein with children

30:49J. Robert Oppenheimer, the director of the atomic bomb project, was stripped of his security clearance
30:55for having suspected leftist associations. Einstein backed Oppenheimer and opposed the development of
31:01the hydrogen bomb, instead calling for international controls on the spread of nuclear technology.
31:08Einstein was also increasingly drawn to anti-war activities and to advancing the civil rights of
31:13African Americans. In 1952, David Ben-Gurion, Israel's premier, offered Einstein the post of President of
31:22Israel. Einstein, a prominent figure in the Zionist movement, respectfully declined the legacy of Albert
31:29Einstein. In a sense, Einstein, rather than being a relic, may have been too far ahead of his time.
31:35The strong force, a key element of any unified field theory, remained a complete mystery during
31:42Einstein's lifetime. Only in the 1970s and 1980s did physicists begin to unravel the secret of the
31:50strong force with the quark model. However, Einstein's work continues to earn Nobel Prizes for subsequent
31:57physicists. In 1993, a Nobel Prize was awarded to the discoverers of gravitational waves, predicted by
32:04Einstein. In 1995, a Nobel Prize was awarded to the discoverers of Bose-Einstein condensates, a new
32:12form of matter that can exist at extremely low temperatures. Known black holes now number in the
32:19thousands. New generations of space satellites have continued to verify Einstein's cosmology.
32:26And many leading physicists are attempting to complete Einstein's ultimate dream, a theory of
32:32everything. Michio Kaku, Michio Kaku, author of the biography of Albert Einstein, is published in the
32:38Encyclopedia Britannica. Einstein wrote the section on space-time for the 13th edition of the Encyclopedia
32:45Britannica. See the Encyclopedia Britannica classic, space-time. Welcome to our channel. Disclaimer,
