The Cyrus Cylinder is an ancient clay cylinder, now broken into several pieces, on which is written an Achaemenid royal inscription in Akkadian cuneiform script in the name of the Persian king Cyrus the Great. [2] [3] It dates from the 6th century BC and was discovered in the ruins of the ancient Mesopotamian city of Babylon (now in modern Iraq ...
The translation of the Nabonidus Cylinder of Sippar was made by Paul-Alain Beaulieu, author of, "The Reign of Nabonidus, King of Babylon 556-539 B.C." [4] [5] [i.1-7] I, Nabonidus, the great king, the strong king, the king of the universe, the king of Babylon, the king of the four corners, the caretaker of Esagila and Ezida, for whom Sin and Ningal in his mother's womb decreed a royal fate as ...
Green line has two intersections. Yellow line lies tangent to the cylinder, so has infinitely many points of intersection. Line-cylinder intersection is the calculation of any points of intersection, given an analytic geometry description of a line and a cylinder in 3d space. An arbitrary line and cylinder may have no intersection at all.
Image of the Blacas ewer. The Blacas ewer is a brass ewer, inlaid with silver and copper, made by an esteemed man, Shuja' ibn Man'a al-Mawsili in Mosul in April or May 1232 (Rajab, 629 AH). [1]
A cylinder is defined as a surface consisting of all the points on all the lines which are parallel to a given line and which pass through a fixed plane curve in a plane not parallel to the given line. [12] Such cylinders have, at times, been referred to as generalized cylinders.
Given a line and any point A on it, we may consider A as decomposing this line into two parts. Each such part is called a ray and the point A is called its initial point. It is also known as half-line (sometimes, a half-axis if it plays a distinct role, e.g., as part of a coordinate axis). It is a one-dimensional half-space. The point A is ...
In geometry, a surface S in 3-dimensional Euclidean space is ruled (also called a scroll) if through every point of S, there is a straight line that lies on S. Examples include the plane, the lateral surface of a cylinder or cone, a conical surface with elliptical directrix, the right conoid, the helicoid, and the tangent developable of a ...
The region of the plane between two concentric circles is an annulus, and analogously the region of space between two concentric spheres is a spherical shell. [6] For a given point c in the plane, the set of all circles having c as their center forms a pencil of circles. Each two circles in the pencil are concentric, and have different radii.
