TRAJAN: A good Roman Emperor

Look at the roman coin. This is the legend:

IMP TRAIANO AVG GER DAC PM TR P COS V PP. Imperator. Trajan. Augustus. Germanicus. Dacicus. Pontifex Maximus. Tribuniciae Potestate. Consul V. Pater Patriae.

TRAJANO: Emperador Trajano. Augusto. Germánico, Dácico. Pontífice Máximo. Con potestad tribunicia. Cónsul por quinta vez. Padre de la Patria.

Ok! Beautiful coin! Now you have to answer two questions. (wiki or whatever)
1. Where was Trajan born?
2. Was he a good emperor or not? Why?

Hypatia of Alexandria and her friends.

Hypatia of Alexandria (370 – 415) was a Greek philosopher who lived in Alexandria (Egypt, Roman Empire). She was the best in mathematics and astronomy in her time.
Hypatia wrote about Euclid (300 BC), who also had lived in Alexandria seven centuries before. He was a Greek mathematician know as the "Father of Geometry." He wrote a book called “Elements” which has been the most influential work in the history of mathematics. It is about geometry, perspective, conic sections, spherical geometry, number theory, etc.
She knew Aristarchus of Samos (310-230 BC) theories about the heliocentric model of the solar system, with the Sun in the center of the universe.
Hypatia also wrote about Eratosthenes of Cyrene (195 BC), who was a very good friend of Arquimedes. Eratosthenes was a Greek mathematician, geographer and astronomer. He was the first who exposed a system of latitude and longitude to represent the Earth. He also calculated the circumference of the Earth with great accuracy. Do you want to know how?
But this tradition had begun with Pythagoras of Samos (570- 495 BC), a Greek philosopher known as "the father of numbers” He was a great mathematician and scientist. Do you know what the Pythagorean teorema is?

Hipatia de Alejandría (370 – 415).

La película de Amenábar ha sacado de la oscuridad a la figura de Hipatia, una intelectual muy importante de finales del s. IV y principios del V, que desarrolló su labor en Alejandría (Egipto) en la fase final del imperio Romano.

También se han publicado últimamente algunas novelas que tratan la vida de esta filósofa de la antigüedad desde perspectivas más rigurosamente históricas o menos, dependiendo de los casos (El sueño de Hipatia, Tormenta sobre Alejandría, etc.).

Hipatia fue profesora, experta en filosofía griega, científica excelente que sobresalió en matemáticas y astronomía. Conocía perfectamente la filosofía antigua y estaba especializada en estudios lógicos y ciencias exactas.
