Story of Geometry

The oldest suggestions of an ordered system of measurements go back to the ancient Babylonians, who developed methods of land surveying embodying calculations of the area of simple geometric figures bounded by straight lines and area of circles. This reflected in the name "geometry", whose literal meaning is Earth measuring.

The assumption of Babylonian astronomers that the year had 360 days is very likely the origin of our system of measuring angles in degrees; the fact that the angles of equilateral triangles are 60 degrees may explain, in part, the hexadecimal method of counting. The Babylonians laid the first foundations of the science of geometry by their purposeful study of the properties of circles. ( the image - a replica from the British museum of a Babylonian ‘math text book’ that depicts the Pythagorean theorem thousands of years before the time of Pythagoras)

Unlike the Egyptians, whose interest in geometry lay exclusively in the practical considerations of land measurement the Greeks devoted their energies to a systematic study of geometrical figures and their properties to establish a new science. Greatest among ancient Greek scientists were Plato and his pupil Aristotle. Other ancient scientists are Eudoxus (theory of proportion and the invention of the method of exhaustion to find approximate areas and volumes of curvilinear forms and shapes - a forerunner of integral calculus), Euclid, Achimedes and many more.

**Easter Number Clip Cards**

So, Easter will be happening soon! I literally have no idea how this happened so quickly! Guys, time with two kids - I don't understand where it goes! Sometimes, the day just seems to drag on, but the weeks and the months seem to go in just a blink of an ey...
