Presentation of our project

Dear colleagues and classmates,

I presented our project to fellow teachers and parents at our end-of-school-year event organised at our school last Friday evening.

We worked really hard this year on a very demanding and interesting project and we are very proud of our work! We wanted everybody to know and we also wanted the parents and the rest of the teachers to meet you, as well.

We are very sorry for the poor quality of our photos! Our photographer was just an amateur and he used the zoom-in button on my cell phone a lot! Pls forgive us and enjoy. We hope we make you proud of our partnership, as well!

Constantinos Daskalakis

Constantinos Daskalakis was born in 1981. He is a university professor. He has also got a lot of degrees. He became famous when he solved the John Forbes Nash puzzle.

John Forbes Nash proved that if there are a lot of general situations, there is always a point of balance. John Forbes Nash won a prize for this invention. He had created a simpler system of relations of the people who have different benefits, such as when playing games. Daskalakis, however, proved that, if we buy something, even if there are different benefits, we can find a balance. However, sometimes this balance is impossible.

For this proof he won a prize by the international organization ACM (Association for Computing Machinery) in 2008.

Our school play

On 23 March all the students, the teachers and a lot of parents  got together at our school’s function room to celebrate our national holiday of 25 March.

We, the students of Grade 3, put on a special play with the help of our PE and English teachers, and it was perfect!

We were preparing for this play for about two months. We missed a lot of lessons and breaks, but we did excellent work!

Below you can see some pictures from our preparations!

We also made amazing scenery, which was like an old traditional house and we wore traditional costumes. In the photos below you can see our costumes and the scenery we made.

I played one of the three main roles, which, although  was very long and very difficult,  made me very happy!

All this preparation period was an interesting and crucial part of my school life!

Valerios Stais

Valerios Stais was a Greek archaeologist of the 19th century. He was born in 1857 in Kythera.

He studied medicine in Athens and later archaeology in Germany. He carried out excavations at Epidauros, in Thessaly, Antikythera, and elsewhere.

Excavation of 1890 by the Greek Archaeological Service under Valerios Stais.

In Antikythera, the world’s first marine archaeological excavation, he recognized the importance of an initially thought as an insignificant finding, and which was later named the Antikythera Mechanism.

Photo of Valerios Stais in diving suit in 1902.

That finding was very interesting and it was the first computational mechanism built around 1500 to 100 BC.

Valerios Stais published many studies and died in 1923.

Eugene Michel Antoniadi

Eugene Michel Antoniadi was a Greek astronomer. He spent most of his life in France. So, on the internet we can find him as a French and Turkish astronomer. Antoniadi was also a very successful chess player.

He studied architecture and he drafted  archaeological drawings of the church of Hagia Sophia in Constantinople.

Antoniadi became a reputed observer of planet Mars. His top observations  were straight canals on planet Mars, which looked like dark lines. Antoniadi concluded that the canals were optical illusions, something that was confirmed by the spacecraft missions to the planet several years later.

Through countless hours of observations he made the first detailed map of the surface of the ‘red planet’. This project was completed by John E. Fokas and the main features of Mars (mountains, areas, craters) have got greek names.

Eugene Antoniadi observed the inside planets Venus and Mercury and tried to draw a map of Mercury. But his efforts were flawed and based on the assumption that Mercury turned always the same hemisphere towards the sun. He invented the scale for the quality of seeing widely used today by amateur astronomers.

Eugene Antoniadi played chess against great players of his time. In the 1907 tournament in Paris he won the first place.

The craters Antoniadis on Mars and

Antoniadi on the southern hemisphere of the Moon have taken their names from this famous astronomer!

Papadiamantis – A play

Dear friends on “Eureka!”,

A couple of weeks ago a very well known Greek actor came to our school and performed some pieces from three of the best works of a very old and very famous Greek author, Alexandros Papadiamantis.

I’ve put together a slideshow presentation for you at this link http://www.kizoa.com/slideshow/d2377912k9652631o1/papadiamantis—a-play and I hope you like it!

And now a few words about the performance.

The play was an old story about a girl and a prince. It took place at the sea on some big rocks. The prince went to war but before he left he told the girl that he would come back at Christmas to marry her. But the prince didn’t come back. Then the girl learned that he had gone to prison. She started crying and at night a green light shines at her house.

I feel unhappy because the girl and the prince didn’t get married. I also feel sad because the prince went to prison.

Philo of Byzantium

Philo of Byzantium was one of the most important mathematicians and engineers of the Hellenistic period.

He was from Byzantium but he lived most of his life in Alexandria.

Constructions

Philo didn’t deal only with theory but he made constructions with which he could prove what he had in mind. His important constructions were the air pump, and the water pump, which worked with buckets.

Apart from these he made some items which worked with steam, like a horse drinking water, a girl pouring water and a siren for a lighthouse. With his last constructions he became the instigator to Heron of Alexandria.

Hecataeus of Miletus

Hecataeus of Miletus was an ancient Greek historian and author. He was born in 545 BC.

He travelled to many countries but he stayed in Egypt a lot. The historical and geographical knowledge he got from his travels he used to write books about the traditions of the various people he met.

Pythagoras of Samos

Pythagoras of Samos (580/572 BC – 500/490 BC) was an important Greek philosopher, mathematician and founder of the Pythagorean theorem. He is best known for this theorem, which was named after him.

He was born on the island of Samos.

Around 350 BC he moved to Croton, a Greek colony in southern Italy and there he set up a religious group. People believe that he died in Metapontum at a big age.

Thales of Miletus

Public

Thales of Miletus (635/630 BC – 543 BC) was a pre-Socratic philosopher and one of the seven wise men of Greece.

He’s known for his grand knowledge and for his amazing ability to discover new things.

Thales tried to explain natural phenomena of the world without using mythology. He was also known for his successful prediction of the sun eclipse in 585 BC.

Timosthenes of Rhodes

Timosthenes of Rhodes (3rd century BC) was an ancient Greek author and admiral in Ptolemy II’s fleet.

Timosthenes described most of the known countries with a lot of precision and located the place of Mediterranean ports and cities.

Scientists and explorers of Antarctica have given his name to a mountain (Timosthenes Mount) in central Antarctica because Timosthenes of Rhodes wrote sailing directions and invented the symbols (wind rose) for  8 or 12 winds. Scientists later used these symbols to make the points of the compass.

Roula Georgiou & Joanna Panagaki, Grade 3, 2nd Junior High School of Paralia

Anaximander

Anaximander (610-546 BC) was the second of the scientists or philosophers who lived in Miletus, like Thales. According to historical documents, he was the best scholar in Astronomy and Geography.

Cosmogony – Cosmology – Astronomy

Anaximander explained the creation of the world beginning from the infinite (Apeiron). He considered that the stars are condensations of gases and fire which are created from swirling.

In Astronomy, Anaximander made sundials. According to Anaximander, the Earth, which is in the middle of the universe, is a sphere with width triple than its length and people live on its surface. Anaximander also formed a theory that life on Earth appeared because of the heat from the sun. The first creatures were like fish and they had shells. People appeared at the end of this stage.

Meteorology

Anaximander believed that the wind was moving air and the rain came from the Earth’s streams. The clap of thunder appears from air escaping from the clouds and when air crashes with clouds, a flash of lighting is created.

Infinity (Apeiron)

The centre of Anaximander’s philosophy was infinity (Apeiron), which has two explanations:

  • the infinite, and
  • the limitless.

Roula Georgiou & Joanna Panagaki, Grade 3, 2nd Junior High School of Paralia

Strabo

Strabo was an ancient Greek historian, geographer, and philosopher. He was the most famous geographer of the ancient times.

Strabo was born in 64 or 63 BC in Amasia in Pontos and he died when he was about 90 years old.

In his journeys he gathered the material which helped him in his writing for historical and geographical works. His biggest works are:

  • Historical Memos, and
  • Geographia

The Historical Memos are 47 books in papyrus. Most of them are lost. The Geographia are 17 books which have been saved. We can say that this work is the most extensive and qualitative map of the world of his time!

In the picture above you can see a crater on the moon that has been named after him!

Autolycus of Pitane

Autolycus of Pitane (c. 350 BC – c. 290 BC) was a Greek astronomer, mathematician and geographer. Autolycus means self-lit, he who has his own light.

In geometry Autolycus studied about the characteristics of the movement of a body at its own projection.

 

Autolycus also studied the relationship between the rising and the setting of the celestial bodies and he wrote that every star that rises and sets, always rises and sets at the same point on the horizon.

 

In memory of Autolycus, one volcano at the north of the moon, at Mare Imbrium (the Sea of Rain) has taken his name.

Erasistratus

Hey children!

As part of our e-twinning project, I’d like to talk to you about one of the greatest ancient Greek doctors and anatomists, called Erasistratus.

Erasistratus was born in Ioulida of Kea, in Kos, in Chios, or in Samos. He lived in Alexandria for some time  and he founded a school of anatomy there.

 

His achievements were many. He thought that the nerves moved a nervous spirit from the brain and he is credited with one of the first in-depth descriptions of the cerebrum and the cerebellum. He also examined the anatomy of the brain and he believed that we feel hungry because our stomach is empty.

 

Erasistratus was also sure that the spleen, the bile, and some other parts of the body were useless to animals. Some valves of the heart may have taken their name from him.

In conclusion, Erasistratus was a bright example of a person who tried to excel in anatomy and he achieved it! People like him should be role models for us!

Pedanius Dioscorides

Pedanius Dioscorides (40 – 90 AD) was a Greek doctor, pharmacologist, and botanist from Anazarbus of Cicilia. He was known for his five-volume work with the biggest influence on pharmacology until 1600 AD.

There are a lot of copies of his work even from the fifth century. He was the greatest pharmacologist of ancient times. His scientific contribution is as great as that of Theophrastos in botany. His manuscripts, which are very interesting, are at the libraries of Vienna, Naples, and Michigan.

Oenopides of Chios

Oenopides was born in Chios at around 500 BC. He lived in Athens where he became an astronomer and a mathematician.

Astronomy

Oenopides’s main accomplishment was the measurement of the angle between the plane of the celestial equator and the zodiac. He found that this angle was 24 degrees. Two centuries later Eratosthenes measured it better. In addition, Oenopides determined the duration of the Great Year to be about 59 years. This hepled to predict eclispes.

Geometry

He pointed out the difference between theorems and problems. The theorem serves for the development of a throery, while a problem is a theorem without development.

 

Furthermore, Oenopides said that for geometric constructions only the ruler (straighthedge) and the compass should be used.

Galenus was born in Pergamos in 129 AD and died in Rome in 199 AD. He was a very good doctor. He was the second best doctor after Hippocrates. he was a doctor of pathology, hygiene, surgery, and pharmacology.

Galenus invented a new medical practice which was used all around the Mediterranean Sea for a long time. He also found out that blood moves through arteries. Before this discovery, people believed that air moved through arteries!

Eudoxus of Cnidus

Eudoxus of Cnidus was born in 404 BC and died in 335 BC. He was a Greek astronomer, geometrist and mathematician. He went to the university of Tarentum and to the academy of Platon in Athens. For many years he lived in Egypt. He is one of the biggest mathematicians of Ancient Greece. He claimed that the world and the space were made from fire!

As you will see in the picture below, a crater on the moon has got its name from this great Ancient Greek scientist!

Soranus

Soranus of Ephesus was an ancient Greek physician. He lived in Rome. He was the most important representative of ancient medicine.

Soranus was the son of Meander and Phoebe. He studied at Ephesus and Alexandria. He worked in Rome during the time of Emperors Trajan and Hadrian.

He belonged to the methodical school and wrote medical and other writings. These writings dealt with gynaecological diseases. He gave emphasis to anatomy. He also wrote a biography of Hippocrates and a dictionary of the parts of the body.

Hippocrates

Hippocrates (Kos 460 B.C. – Larissa 377 B.C.) was an ancient Greek physician and one of the most important persons in the history of medicine.

Hippocrates introduced rational medicine away from metaphysical elements, superstitions , prejudices, and the demonology of his time. He managed to match science based on the man with the art of medicine and the philosophical reflection. Hippocrates practised medicine based on humanistic and ethical values, successfully.

His work affected many modern medical specialities and so Hippocrates is today considered the father of medicine.

Finally, he promoted the systematic study of clinical medicine, and he wrote instructions for doctors in his Corpus Hippocraticum.

Detail of a 1532 woodcut showing Herophilus (left) and Erasistratus

Herophilus of Chalcedon (331-280 B.C.) was a Greek doctor. He was born in Chalcedon in Asia Minor in 331 B.C. and he flourished in Alexandria in 300 B.C.

Along with Erasistratus he is regarded as the founder of the great medical school of Alexandria. He was an excellent pathologist, pharmacologist, gynaecologist, obstetrician, and, probably, surgeon.

 

 

 

He studied the brain, recognising the centre of the nervous system as the seat of the mind. He also studied the nervous system over and over again distinguishing the nerves from the blood vessels and the motor ones from the sensory nerves. But education of the anatomical studies includes the eye, liver, pancreas and the digestive system, the salivary glands, and the reproductive system.

Herophilus was a scientist who founded the scientific method.

Seleucus of Seleucia

Seleucus of Seleucia was a great ancient Greek mathematician and astronomer. He solved many astronomical problems of his time, mainly the earth’s rotation around its axis and around the sun (heliocentric system or model).

Seleucus of  Seleucia is the first who discovered the relationship between the phenomenon of tides and the movement of the moon. More specifically, he observed the tides in the Red Sea for a long time and he revealed their relationship with the different positions of the moon in the zodiac cycle.

Also he explained the phenomenon of the annual flood as the reason for the resistance of the moon to the next rotation of the atmosphere. This certainly does not seem to happen, but at least he was the first to distinguish the inequality in the rotational speed of the earth’s atmosphere.

Sadly, none of his writings were preserved.

Menaechmus

Menaechmus was an important geometer of Ancient Greece in the 4th century BC. He was the teacher of Alexander the Great in Mathematics. He was considered the first who discovered and singled out the three types of conic sections:

ellipse

parabola, and

hyperbola.

He also dealt with doubling the cube, known as the Delian problem.

Apart from these he dealt with astronomy.

Aglaonike

Aglaonike (also known as Aganike of Thessaly http://en.wikipedia.org/wiki/Thessaly) is the first female astronomer in ancient Greece!

She is mentioned in the writings of historians’ as the daughter of Hegetor of Thessaly. People believed she was a witch because she had the ability to make the moon disappear from the sky. People also believed that because of her ability she could predict the exact time and area where a lunar eclipse would occur.

Did you know that a crater on the moon has got its name from Aglaonike?

Hipparchus of Rhodes

Hipparchus of Rhodes or Hipparchus of Nicaea (190-120 BC) was a Greek astronomer, geographer, cartographer and mathematician. People call him “the father of astronomy”.

In the 2nd century BC he calculated that the solar year is 365.242 days.

In 143 BC Hipparchus set the basis of Astronomy because he claimed that the stars aren’t eternal on the sky.

Hipparchus has invented the astrolabe.

He perfected the Dioptra

and other older instruments like the hourglass

the links (rings)

the solid ball and the sundial

He was also the first person who made the terrestrial globe.

In 2006 a research team announced that a group of toothed wheels inside the mechanism represented the moon’s speed. They believe that Hipparchus was involved with the construction of that instrument.

Finally, he created the first star catalogue, which unfrotunately has been lost.

Aristarhos from Samos

Aristarhos was born in 310 BC and died in 230 BC. He was a Greek astronomer and a Maths teacher. He was born in Samos.

He suggested that the sun was the centre of the solar system. Originally, his ideas about astronomy were not accepted. He observed the movement of the moon and claimed that the diameter of the Earth was three times bigger than the diameter of the moon. He reached the conclusion that the sun had a diameter twenty times bigger than that of the moon and that the sun is bigger than the Earth.

In the picture above you can see “Aristarhos”, the second biggest telescope in Europe named after  this great Greek astronomer, and which is on the mountain in Kalavryta, a town about 80 kms away from Patra.

Andronicus of Cyrrhus

Andronicus of Cyrrhus was an ancient Greek engineer. He was from Cyrrhus . He was Hermia’s son.

He made the sundial from white marble, the celestial globes and other astronomic instruments.

He also built a clock in Athens, which is known as the Tower of Winds and you can see it even today.

Eratosthenes (276 BC – 195 BC)

Portrait of Eratosthenes

Hello children!

I’m a student from 2nd Junior High School of Paralia and I’d like to talk to you about a very important scientist who lived in Ancient Greece. His name was Eratosthenes of Cyrene and he really achieved great things!

Eratosthenes of Cyrene was a great mathematician, geographer and astronomer. He was born in Cyrene in 276 BC and died in the capital of Ptolemaic Egypt in 195 BC. Eratosthenes studied in Alexandria and it was believed that he had also studied in Athens for some years.

Eratosthenes was the first person that calculated the circumference of the Earth and he also invented a system of latitude and longitude. He made a map of the known world, as well. Below you can see a reconstruction of his map in the 19th century.

Eratosthenes' map of the world (194 B.C.)

He made a lot of important contributions to mathematics and science and he was a good friend of the great physist and mathematician Archimedes (the person who first shouted “Eureka!”, remember?).

Around 255 BC he invented the armillary sphere and he also found the distance to the sun and the moon. Below you can see a diagram of what an armillary sphere looks like.

As you can understand, Eratosthenes was a very successful man in almost every field of science.

In my opinion, he is a bright example of a person that worked hard and helped the world become a better place!
