Blender’s main internal functionality (including GUI and editors) has been developed in C language. C++ has been used for writing game-engine, physics, audio functionality and render engine.

There is also a Python API for Blender with a very good documentation. This API can be used for building addons, and can also be used as a powerful tool for simplifying certain tasks by those who are familiar with Python.

Well do I know that I am mortal, a creature of one day.
But if my mind follows the winding paths of the stars
Then my feet no longer rest on earth, but standing by
Zeus himself I take my fill of ambrosia, the divine dish.

Above lines which appear in the Book 1 of the Almagest are accepted by many scholars to have been written by Ptolemy himself. Claudius Ptolemy was one of the most reputed mathematician, geographer, astronomer and perhaps also a poet of ancient times. He was born in Egypt around 85AD. He development trigonometry and devised many new geometrical proofs and theorems. He formulated the coordinate system of longitudes and latitudes which is immensely used in geography and astronomy.

Very little is known about Ptolemy’s life. During the years AD 127-41, he made astronomical observations from Alexandria in Egypt and also formulated a geocentric model of astronomy. As we know today, this model had many errors. However, for around 1500 years it was satisfactorily used by astronomers to fit their observational data.
