Roland is depicted as a brave and loyal knight devoted to his emperor Charles. However, he is also portrayed as arrogant, dogmatic, and disrespectful towards his stepfather Ganelon. Roland refuses help from Charles and advice from Oliver due to overconfidence in his own abilities. This hubris leads to the defeat of the Frankish army at the hands of the Saracens. Only as he sees his comrades slaughtered does Roland realize his mistake. In the end, though, Roland is vindicated for his bravery and heroic sacrifice in battle.
The document summarizes key aspects of the character El Cid from different sources. It discusses his portrayal in a film as courageous and principled, forgiving even his enemies. It then analyzes the portrayal of women characters like his wife Jimena and daughters in the epic poem, exploring their loyalty, respect and mistreatment. Finally, it notes three stanzas from the poem of El Cid that were set to music from another Cretan poem.
Aeneas' journey as a refugee began after the destruction of Troy, when he left with his father, son, and troops to search for a new homeland. After years of wandering, they eventually settled in Italy, where Aeneas became the ancestor of the Romans. Centuries later, the destruction of Smyrna in 1922 caused over 1 million Greek refugees to flee Asia Minor. They arrived in Greece in poor condition, with many subsequently dying. Though initially housed in poor conditions, the refugees eventually integrated and contributed greatly to Greece's economy, culture, and society. Today, Greece continues to receive large numbers of migrants and refugees, particularly children, fleeing conflicts around the world.
This document contains a table of contents for information about Virgil's Aeneid, including sections on Publius Vergilius Maro, the composer of the Aeneid, main characters in the story, a summary of the plot, and the historical reality behind the myth of Rome's founding. The summary section outlines the journey of Aeneas from Troy to Italy, including stops in Carthage and Sicily, and his battles with Turnus in Italy. The reality section notes that while legends say Rome was founded by Romulus and Remus, historians believe it emerged from the settlement of Greek, Etruscan, and Italian tribes in central Italy around 753 BC.
This document tells the story of Mohajer, a 14-year-old Syrian boy who is diabetic. His mother has died and he is trying to get to Germany to find his father. He travels through Turkey and Greece by truck and boat with other refugees. When he reaches a Greek island in the rain, Greek officers find him and he tells them his name is Mohajer and he is going to find his father.
Ancient Greek and Roman comedy developed over centuries, beginning in 5th century BC Athens. The earliest comedies by playwrights like Aristophanes used satire to critique politics and society while entertaining audiences. This tradition evolved into New Comedy plays in the Hellenistic era by Menander that focused more on everyday domestic life. Roman writers like Plautus and Terence adapted Greek New Comedy plays to Latin, influencing later European dramatists like Moliere. Ancient comedy aimed to both amuse and teach audiences while addressing social issues through humor and satire.
Greek and Latin symbols have been used in mathematics since ancient times to concisely represent mathematical concepts and operations. Mathematical symbolism plays an important role in both teaching and learning mathematics, as it provides a powerful communication tool for teachers and students. A strong understanding of mathematical symbols helps students translate between the language they speak and the language of mathematics, which is crucial for successful learning.

Η Άλγεβρα Boole
1. Η Άλγεβρα Boole και πώς αυτή συνδέεται
με τους αλγορίθμους και το υλικό του
υπολογιστή.
Ευθύμιος Κλήμης
Μαρία Κυριακού
2. Η άλγεβρα Boole
Η άλγεβρα Boole πήρε το όνομά της από τον Άγγλο
George Boole(1815-1864). Ήταν ο πρώτος που
διατύπωσε τους βασικούς κανόνες με τους οποίους οι
λογικές προτάσεις μπορούν να παρουσιαστούν με
μαθηματικά σύμβολα. Οι κανόνες αυτοί
χρησιμοποιούνται για να λύσουμε λογικά προβλήματα.
Στην άλγεβρα Boole υπάρχουν μόνο δύο είδη
προτάσεων, αυτές που είναι αληθείς και αυτές που
είναι ψευδείς. Οι μεταβλητές αυτές μπορούν να
πάρουν δύο τιμές: 0(ψευδείς) και 1(αληθείς).
3. Η άλγεβρα Boole συνδέεται με τα μαθηματικά μέσω των
λογικών πράξεων.
Οι λογικές πράξεις είναι οι εξής:
Άλγεβρα Boole και
μαθηματική λογική
4. 1. Η πράξη NOT (ΌΧΙ)
Στην πράξη αυτή συμμετέχει μόνο μία λογική μεταβλητή
και το αποτέλεσμα της είναι το αντίστροφο της
μεταβλητής αυτής.
2. Η πράξη AND
Συμμετέχουν 2 λογικές μεταβλητές και το αποτέλεσμά
τους είναι αληθές αν και η δυο είναι αληθείς.
3. Η πράξη OR
Συμμετέχουν 2 μεταβλητές και το αποτέλεσμα τους είναι
αληθές αν έστω μια από τις δυο είναι αληθή.
ΑΥΤΕΣ ΑΠΟΤΕΛΟΥΝ ΤΙΣ ΒΑΣΙΚΕΣ ΛΟΓΙΚΕΣ πράξεις….
5. …….Υπάρχουν όμως και κάποιες άλλες
λογικές πράξεις και είναι οι εξής:
i. NAND
ii. NOR
iii. XOR
iv. XNOR

8. Συμπεραίνοντας…
Η τεχνολογία των Η/Υ χρησιμοποιεί το δυαδικό σύστημα για την
αναπαράσταση της πληροφορίας με δύο καταστάσεις.
Αναφέρεται σε μεταβλητές που παίρνουν 2 τιμές(0,1)
(αληθής,ψευδής) και ονομάζονται ΛΟΓΙΚΕΣ ΜΕΤΑΒΛΗΤΕΣ.
Ορίζονται οι συντελεστές( AND, OR & NOT)
9. Άλγεβρα Boole και υλικό
υπολογιστών
Η άλγεβρα Boole είναι ιδιαίτερα
χρήσιμη για τον σχεδιασμό και την
ανακάλυψη των ηλεκτρονικών
κυκλωμάτων που υλοποιούν τις
λειτουργίες των Η/Υ. Η άλγεβρα Boole
συνδέεται με το υλικό των
υπολογιστών μέσω των ΛΟΓΙΚΩΝ
ΠΥΛΩΝ.
10. ΛΟΓΙΚΕΣ ΠΥΛΕΣΟι λογικές πύλες είναι τα βασικά δομικά στοιχεία στα ψηφιακά
κυκλώματα.
Στον παραπάνω πίνακα φαίνονται οι σχηματικές αναπαραστάσεις των λογικών
πυλών και οι αντίστοιχοι πίνακες που περιγράφουν τη λειτουργία τους.
