Some historians say that Pythagoras was married to a woman named Theano and had a daughter Damo, and a son named Telauges, who succeeded Pythagoras as a teacher and possibly taught Empedocles. Others say that Theano was one of his students, not his wife, and say that Pythagoras never married and had no children.

Educated at the universities of Pavia and Padua, Cardano received his medical degree in 1526. In 1534 he moved to Milan, where he lived in great poverty until he became a lecturer in mathematics. Admitted to the college of physicians in 1539, he soon became rector. His fame as a physician grew rapidly, and many of Europe’s crowned heads solicited his services; however, he valued his independence too much to become a court physician. In 1543 he accepted a professorship in medicine in Pavia.

Cardano was the most outstanding mathematician of his time. In 1539 he published two books on arithmetic embodying his popular lectures, the more important being Practica arithmetica et mensurandi singularis (“Practice of Mathematics and Individual Measurements”). His Ars magna(1545) contained the solution of the cubic equation, for which he was indebted to the Venetian mathematician Niccolò Tartaglia, and also the solution of the quartic equation found by Cardano’s former servant, Lodovico Ferrari. His Liber de ludo aleae (The Book on Games of Chance) presents the first systematic computations of probabilities, a century before Blaise Pascal and Pierre de Fermat. Cardano’s popular fame was based largely on books dealing with scientific and philosophical questions, especially De subtilitate rerum (“The Subtlety of Things”), a collection of physical experiments and inventions, interspersed with anecdotes.

Cardano’s favourite son, having married a disreputable girl, poisoned her and was executed in 1560. Cardano never recovered from the blow. From 1562 he was a professor in Bologna, but in 1570 he was suddenly arrested on the accusation of heresy. After several months in jail he was permitted to abjure privately, but he lost his position and the right to publish books. Before his death he completed his autobiography, De propria vita (The Book of My Life).

HAREZMİ HAYATI
IX yy da yaşamış olan ünlü matematik, coğrafya ve astronomi alimi, Cebir" Biliminin Kurucusu "El Harezmi" 'dir. 780 yılında Harezmi de doğan ünlü alim dönemin bilgi merkezi ve şehri olan Bağdat’a ilim öğrenmek için gider. Bağdat'ta bulunan Bilim Akademisi Darülhikme’de görev alan Harezmi matematik, coğrafya ve astronomi dallarında çalışmalar yapmıştır.
Harezminin buluşları ise birinci ve ikinci dereceden denklemleri analitik metotla tek bilinmeyenli denklemleri ise cebirsel ve geometrik metotlarla çözmenin yollarını buldu. Harezminin en büyük özelliği ise Matematik’te ilk kez sıfırı kullanan birisidir.
Matematik alanına Cebir kavramını sokan Harezmi ilgi duyduğu matematik, coğrafya ve astronomi dallarında birçok eser yazdı.

IX. yy. ‘da yaşamış olan ünlü matematik, coğrafya ve astronomi alimi, Cebir Biliminin kurucusu "El Harezmi" 'dir. 780 yılında Harezmi’ de doğan ünlü alim dönemin bilgi merkezi ve şehri olan Bağdat’a ilim öğrenmek için gider. Bağdat' ta bulunan Bilim Akademisi Darülhikme’de görev alan Harezmi, matematik, coğrafya ve astronomi dallarında çalışmalar yapmıştır.

Harezmi’ nin buluşları ise birinci ve ikinci dereceden denklemleri analitik metotla, tek bilinmeyenli denklemleri ise cebirsel ve geometrik metotlarla çözmenin yollarını buldu. Harezmi’ nin en büyük özelliği ise Matematik’ te ilk kez sıfırı kullanmasıdır.
Matematik alanına Cebir kavramını sokan Harezmi ilgi duyduğu matematik, coğrafya ve astronomi dallarında birçok eser yazdı.

This great work of Harezmi was translated into Latin in the 12th century by Robert of Chester and Gerard by Cremone. The Western world was greatly influenced by this work and thus learned algebra. Algebra in the western world, algebra-albras name has been converted. It was later defined as algebra in the western languages. At the same time, this work of Harezmi played an important role in the spread of algebra in the western world.
Harezmi Muhammad ibn Ibrahim al-Fizari's Sanskrit language translated from Arabic to Arabic-al-Sindhind (Siddhanta) by taking advantage of Ptolem's Almagest also corrected.
This work has been reproduced in two different ways. This artwork contained theoretical information. Later this work was updated by the astronomer Meslemet al-Mecriti. This version of the work was translated into Latin by the efforts of Adelard the Bath and later probably by the Dalmatian Hermann. The biggest oddity in the work is that Harezmi has tables that indicate the angles of the Pyramid with trigonometric functions like sinuses. Of course, these paintings have raised many questions because Harezmi knew trigonometric functions or was added by Meslemetü Mecriti later. However, most historians of science say that the sine and cosine were used by Haromacy for the first time. The tangent and cotangent is claimed to have been added by Meslemetü'l Mecriti. But whatever trigonometry belongs to the world of Islamic science. The fact that trigonometry is the work of the Islamic world is a good answer to those who claim that Islam does not have enough knowledge about it. Of course, not only trigonometry, mathematics, astronomy, geography, physics, medicine, such as science, the science of science has advanced much in the world.
The work of Harezmi about the construction and use of the astrolabe, which is one of the important works, is lost. Khwarezmi was concerned not only with mathematics but also with geography. He translated Ptolemy's Geography as 'Kitabu Sureti'l Ard' (About the Format of the Earth). In this way, the Greeks played an important role in the introduction of information about mathematical geography into the world of Islamic science. This work has been added to the translation of the originality has been a little lost. This work of Khwarezmia contains a number of tables reporting the latitudes and longitudes of important places. One of the most interesting works of Harezmi is the map showing the source of the Nile. This work was later known as the Ptolemy-Harizmi Theorem. Harezmi worked with 70 scientists in 830 to draw a world map. world.

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led him to develop his special theory of relativity during his time at the Swiss Patent Office in Bern (1902–1909). However, he realized that the principle of relativity could also be extended to gravitational fields, and he published a paper on general relativity in 1916 with his theory of gravitation. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, he applied the general theory of relativity to model the structure of the universe.

Except for one year in Prague, Einstein lived in Switzerland between 1895 and 1914, during which time he renounced his German citizenship in 1896, then received his academic diploma from the Swiss federal polytechnic school (later the Eidgenössische Technische Hochschule, ETH) in Zürich in 1900. After being stateless for more than five years, he acquired Swiss citizenship in 1901, which he kept for the rest of his life. In 1905, he was awarded a PhD by the University of Zurich. The same year, he published four groundbreaking papers during his renowned annus mirabilis (miracle year) which brought him to the notice of the academic world at the age of 26. Einstein taught theoretical physics at Zurich between 1912 and 1914 before he left for Berlin, where he was elected to the Prussian Academy of Sciences.

In 1933, while Einstein was visiting the United States, Adolf Hitler came to power. Because of his Jewish background, Einstein did not return to Germany.^[13] He settled in the United States and became an American citizen in 1940.^[14] On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential development of "extremely powerful bombs of a new type" and recommending that the US begin similar research. This eventually led to the Manhattan Project. Einstein supported the Allies, but he generally denounced the idea of using nuclear fission as a weapon. He signed the Russell–Einstein Manifestowith British philosopher Bertrand Russell, which highlighted the danger of nuclear weapons. He was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955.

 The greatest success of Pythagoras is the discovery that the music is based on proportional ranges of numbers 1, 2, 3, 4.  Pythagoras said that the universe was based on the number 10 (1 + 2 + 3 + 4 = 10), which is the sum of these numbers.

 He was one of the first to say that the world is round, that every planet has an axis and that the planets have returned at a central point.  Although he first drew this point as the world, he gave up this idea and said that the planets had revolved around a central fire.  But this never defines fire as the Sun.  He also believed that the Moon was another planet and called it the Counter-World.

 Pythagoras also dealt with music.  With the shortening of the wire, he discovered that his voice was getting thinner.  If the length of one of the two wires is two times longer than the other, the sound of the short wire saw that the sound produced by the long wire is above one octave.

Pythagoras is the first Greek who understands that the morning star and the evening star are the same star. 

 After this star for a long time called Aphrodite.  Today we know that this is the planet Venus.

 Pythagoras reacted quite harshly when he suggested that the Earth revolved around the Sun.

  It was Pythagoras, who brought the idea of ​​proof and axiomatic thinking to mathematics.  The discovery of the multiplication ruler and its application to the geometry is also said to have been made by Pythagoras.

Pythagorean Theorem (Pisagor Teoremi)

  In a right-angled triangle, the sum of the squares of the lengths of each of the steep edges is equal to the square of the length of the hypotenuse.  The mathematical representation of this theorem is:

 It is said that he invented and used a kind of trophy, which provides a fair distribution of the drink put into it, called the Pythagorean cup.  If a certain level of drink is placed into the cup, the mechanism in excess of the stone would be over.
