OK. 624 - 546 BC

slide 2

Greek philosopher and mathematician from Miletus. Thales was a noble family. He traveled extensively in different countries using these journeys to expand and acquire knowledge. Founder of the Milesian school.

In Egypt, he studied the causes of floods, found a way to measure the height of the pyramids. Thales of Miletus is credited with a simple way to determine the height of the pyramid. On a sunny day, he placed his staff where the shadow of the pyramid ended. He then showed that just as the length of one shadow is related to the length of another shadow, so the height of the pyramid is related to the height of the staff.

He became famous in Greece for having successfully predicted a solar eclipse in 585 BC.

slide 5

Having collected astronomical information received from the Egyptian priests, together, Thales once ventured to predict a solar eclipse. Naturally, they did not believe him at first. Yes, and not before the Milesians. It was on that day that the battle of the Medes with the Lydians was scheduled. And the citizens of Miletus were animatedly discussing the question of whether they should intervene in someone else's fight. Thales spoke out strongly against the war. The Milesians stayed at home. What happened next? No sooner had the bronze swords of the Medes hit the no less bronze shields of the Lydians than the sky began to darken. On the bright face of Helios - the Sun moved black spot. The terrified warriors dropped their weapons and gave thrust. And the Miles? Frightened mainly by the magical accuracy of Thales's prediction, they still found the strength to lay down the chariots and leave for the field of the failed battle. There they loaded wagons with abandoned equipment, grabbed some of the neighbors who did not have time to escape, turning them into slavery right there. After this event, the fame of Thales increased incredibly

He also has merits in the field of creation of scientific mathematics. So, it is believed that he was the first to manage to inscribe a triangle in a circle. Thales was the first to prove geometric theorems; he owns the proofs of the following statements: 1) the circle is divisible by the diameter in half; 2) in an isosceles triangle, the angles at the base are equal; 3) at the intersection of two straight lines, the vertical angles formed by them are equal; 4) two triangles are congruent if two angles and the side of one of them are equal to two angles and the corresponding side of the other.

All this brought Thales the glory of the first sage of the famous "seven wise men" of antiquity. Thales of Miletus had the title of one of the seven sages of Greece, he was truly the first philosopher, the first mathematician, astronomer and, in general, the first in all sciences in Greece. He was to Greece what Lomonosov was to Russia.

Plutarch cites the following original statements of Thales: “What is most beautiful of all? - The world, for everything that is beautifully arranged is part of it. What is the wisest thing? - Time, it gave birth to one thing and will give rise to another. What is common to all? - Hope: they have it and those who have nothing else. What is most useful? - Virtue, because, thanks to it, everything else can find application and become useful. What is the most harmful? - Vice, because in its presence almost everything deteriorates. What is strongest? - Necessity, for it is irresistible. What is the easiest? - That which corresponds to nature, for even pleasures often tire."

Unfortunately, the sages are mortal in the same way as all other people, even if they are not marked with the seal of genius. There is a legend that during one of the Olympics, an elderly sage, he was, by the way, a passionate fan, excited by the victory of either his son or grandson, stood up on the bench, shouted “glory!” and fell dead right in the stadium. The townspeople buried Thales. An inscription was carved on his tomb, which reads: "How small is this tomb of Thales, so great is the glory of this king of astronomers in the region of the stars." And ... forgot. Forgotten his advice.

Canon of the Seven Wise Men
· "Measure is the most important thing," - Cleobulus used to say Lindian; · In Sparta "Know thyself!" - Chilo preached; · Restrain anger exhorted Periander, a native of Corinth; · "Lishku in anything!" - the proverb was Pittaka's Mytilene; · "Watch the end of life!" - repeated by Solon of Athens; · "The worst everywhere are the majority!" - said Biant Priensky; "Don't vouch for anyone!" - Thales of Miletus word.

Biography facts The name of Thales already in the 5th century. BC e. became a household word for a sage. Thales is called the "father of philosophy" already in his time. It is only known for certain that Thales was of a noble family, and received a good education in his homeland. The name of Thales already in the 5th century. BC e. became a household word for a sage.

Thales is reported to have been a merchant and traveled widely. For some time he lived in Egypt, in Thebes and Memphis, where he studied with the priests, studied the causes of floods, and demonstrated a method for measuring the height of the pyramids. It is believed that it was he who “brought” geometry from Egypt and introduced the Greeks to it. His activities attracted followers and students who formed the Milesian (Ionian) school. Tradition depicts Thales not only as a philosopher and scientist, but also as a "subtle diplomat and wise politician"; Thales is reported to have been a merchant and traveled widely.

Tradition depicts Thales not only as a philosopher and scientist proper, but also as a “subtle diplomat and wise politician”; Thebes Memphis Milesian (Ionian) school


Some sources claim that Thales lived alone and shunned the affairs of state; others that he was married, had a son Kibist; the third is that, remaining a bachelor, he adopted his sister's son. The life of Thales is reduced to the period from to BC. this is. Thales could die at the age of 76 to 95 years.. It is believed that there is one exact date associated with his life, 585 BC. e., when there was a solar eclipse in Miletus, which he predicted (according to modern calculations, the eclipse occurred on May 28, 585 BC, during the war between Lydia and Media) BC. e. 585 BC e. Lydia Mussel


Compositions Tradition most consistently ascribes two compositions to Thales. The first, "On the Turns of the Sun and the Equinox", its content is known only in the transmission of later authors, and often without indicating the source. Second, "Naval (marine) astronomy"; the authorship of Thales in writing this book was questioned by the ancient Greeks themselves. (Perhaps this is only a tribute to the tradition, according to which it is believed that Thales was the first in the ancient world to engage in astronomy on a truly scientific basis.) In general, according to tradition, the complete collection of his works was only 200 verses. Tradition most consistently ascribes two works to Thales.

Astronomy It is believed that Thales was the first (of the ancient scientists known today) to study the movement of the Sun in the celestial sphere. He discovered the inclination of the ecliptic to the equator, establishing that "the zodiac is superimposed obliquely on the three middle circles, touching all three." He learned to calculate the time of solstices and equinoxes (the main four of the eighteen astronomically and calendar significant events), established the uneven intervals between them.

He learned to calculate the time of the solstices and equinoxes (the main four of the eighteen astronomically and calendar significant events), established the unequal intervals between them. he found that the size of the Sun is 1/720 of its circular path, and the size of the Moon is the same part of the lunar path. Thales was the first to determine the angular size of the Moon and the Sun; he found that the size of the Sun is 1/720 of its circular path, and the size of the Moon is the same part of the lunar path.


Thales was the first to claim that the Moon shines by reflected light; that eclipses of the Sun occur when the Moon passes between it and the Earth; and lunar eclipses occur when the moon is in the shadow of the earth. Thales was the first to claim that the Moon shines by reflected light; that eclipses of the Sun occur when the Moon passes between it and the Earth; and eclipses of the moon occur when the moon falls into the shadow of the earth. eclipses Thales introduced a calendar, according to the Egyptian model (in which the year consisted of 365 days, divided into 12 months of 30 days, and five days remained falling out). Thales introduced a calendar, following the Egyptian model (in which the year consisted of 365 days, divided into 12 months of 30 days, and five days remained falling out). Thales is said to have "invented the globe". It is believed that Thales "discovered" the constellation Ursa Minor for the Greeks as a guiding tool. It is believed that Thales "invented the globe." mathematical method» in the study of the motion of celestial bodies. It can be argued that Thales (starting with the geometric study of angles) created a "mathematical method" in the study of the motion of celestial bodies.


Geometry It is believed that Thales was the first to prove several geometric theorems, namely: vertical angles are equal; vertical angles are equal; triangles with equal one side and equal angles adjacent to it are equal; triangles with equal one side and equal angles adjacent to it are equal; the angles at the base of an isosceles triangle are equal; the angles at the base of an isosceles triangle are equal; the diameter bisects the circle; the diameter bisects the circle; An angle inscribed in a semicircle will always be a right angle. An angle inscribed in a semicircle will always be a right angle. if parallel lines intersecting the sides of an angle cut off equal segments on one side of it, then they cut off equal segments on its other side. if parallel lines intersecting the sides of an angle cut off equal segments on one side of it, then they cut off equal segments on its other side.


Cosmogony Thales believed that everything is born from water; everything arises from water and turns into it. The beginning of the elements that exist in things is water; the beginning and end of the universe is water. Everything is formed from water by its solidification / freezing, as well as evaporation; When it condenses, water becomes earth; when it evaporates, it becomes air.

Thales spent a lot of time traveling. Engaged in research on natural phenomena and reflections, Thales squandered his money and lived poorly. He taught that man needs wisdom, not money. The inhabitants of his native Miletus mocked him. Thales spent a lot of time traveling. Engaged in research on natural phenomena and reflections, Thales squandered his money and lived poorly.

Thales thought for a long time about how to get rich and came up with. He borrowed money and bought up all the oil mills in the city. According to his forecast, there should have been an unusually large harvest of olives .. Aristotle emphasizes: Thales predicted the harvest "by observing the stars", that is, thanks to knowledge. And when the forecast came true, Thales earned a fortune in one autumn. Thus, Thales proved that if he were interested in money, then with his knowledge and mind he could become richest man. “You teach people, but you yourself live in poverty,” they told him.

They say that one night Thales walked without looking at his feet and looked at the starry sky. He stumbled and fell into a hole. People began to laugh at him, and one woman said: - Well, wise man, do you want to know what is in heaven, but you don’t even see what is under your feet?

Another famous philosopher, Hegel, answered it already in the 19th century. “Those who laugh at philosophers will never fall into a pit,” he said. “After all, they are already at the very bottom of it.

Often the beginning of the development of astronomy and geometry is associated with the name of Thales. According to Apuleius: "Thales of Miletus, undoubtedly the most outstanding of those famous seven sages (after all, he was the first discoverer of geometry among the Greeks, and the most accurate tester of nature, and the most experienced observer shined)".


The date of the death of the first philosopher is unknown. Diogenes Laertes writes: “Thales died, looking at gymnastic competitions, from heat, thirst and senile weakness. On his tomb it is written: This tomb is small, but the glory over it is immense: In it, the wise Thales is hidden before you.

Another famous philosopher, Hegel, answered it already in the 19th century. “Those who laugh at philosophers will never fall into a pit,” he said. “After all, they are already at the very bottom of it.

Often the beginning of the development of astronomy and geometry is associated with the name of Thales. According to Apuleius: "Thales of Miletus, undoubtedly the most outstanding of those famous seven sages (after all, he was the first discoverer of geometry among the Greeks, and the most accurate tester of nature, and the most experienced observer shined)".


The date of the death of the first philosopher is unknown. Diogenes Laertes writes: “Thales died, looking at gymnastic competitions, from heat, thirst and senile weakness. On his tomb it is written: This tomb is small, but the glory over it is immense: In it, the wise Thales is hidden before you.

Thales (625 BC - 547 BC), ancient Greek philosopher, mathematician, founder of ancient philosophy and science, founder of the Milesian school, originally from Miletus (Asia Minor) Predicted a solar eclipse on May 28, 585 BC. Thales discovered the inclination of the ecliptic to the equator, determined the angular magnitude of the moon. The first to introduce the principle of mathematical proof into mathematics, he proved several theorems of geometry. Traditionally considered the founder of Greek philosophy (and science) - he invariably opened the list of "seven wise men" who laid the foundations of Greek culture and statehood[

Thales of Miletus is credited with a simple way to determine the height of the pyramid. On a sunny day, he placed his staff where the shadow of the pyramid ended. He then showed that just as the length of one shadow is related to the length of another shadow, so the height of the pyramid is related to the height of the staff. The legend tells that Thales, while in Egypt, struck Pharaoh Amasis by being able to accurately determine the height of the pyramid, waiting for the moment when the length of the shadow of the stick becomes equal to its height, and then measured the length of the shadow of the pyramid.

Thales can rightly be called a scientist, because he is one of the first who went beyond religion in his work and research. Theorems formulated and proved by Thales. Namely; vertical angles are equal; there is an equality of triangles on one side and two angles adjacent to it; the angles at the base of an isosceles triangle are equal; the diameter bisects the circle; An inscribed angle based on a diameter is a right angle. Thales learned to determine the distance from the coast to the ship, for which he used the similarity of triangles. This method is based on a theorem later called the Thales theorem.

The story of one prediction. Traveling in Egypt, Thales collected a lot of astronomical information from the Egyptian priests. Having collected enough knowledge, he decided to predict a solar eclipse, but at first no one believed him. During the eclipse, a battle was scheduled between the Lydians and the Medes, and the Milesians thought of intervening, but Thales persuaded them to stay away. And only the enemy maples had to come down and it began to get dark. They threw away all their weapons and armor and fled, and the Milesians, knowing that they had loaded all the weapons and armor onto the wagons, and tidied them up for themselves. That's how they began to call him "the king of the stars."

Death of a sage. According to legend, death lay in wait for Thales at the Olympics, he was rooting either for his son, or for his grandson, he got up from the bench and shouted “glory! ' and dropped dead. And the townspeople buried Thales, and an inscription was knocked out on the tomb: "How small is this tomb of Thales, so great is the glory of this king of astronomers in the region of the stars."

Finding the distance to an inaccessible object. Sometimes it is necessary to measure the distance to an inaccessible object. For example, the width of the river. We do it in the following way. Having outlined some clearly visible object (A) (tree, rock) on the opposite bank of the river, located near the water itself, you need to stand exactly opposite it and mark a point by placing a pebble on the ground or sticking a peg B, then walking along the coast along a line perpendicular to to the direction between the object on the other side and the peg, you need to count 30 steps and stick a stick into the ground (B). After walking in the same direction for the same number of steps, again make a mark on the ground (G) and, walking from it, turning your back to the river, count the steps, from time to time looking at the object marked on the other side. When stick B, stuck on the bank, is in line with object A across the river, then the distance (D - D) from the last mark to the final stop (D) will be equal to the width of the river.
