UbD is an example of backward design, the practice of looking at the outcomes first, and focuses on teaching to achieve understanding. It is advocated by Jay McTighe and Grant Wiggins (1950-2015) [2] in their Understanding by Design (1998), published by the Association for Supervision and Curriculum Development. [3]
2.5D (basic pronunciation two-and-a-half dimensional) perspective refers to gameplay or movement in a video game or virtual reality environment that is restricted to a two-dimensional (2D) plane with little to no access to a third dimension in a space that otherwise appears to be three-dimensional and is often simulated and rendered in a 3D digital environment.
A sphere in 3-space (also called a 2-sphere because it is a 2-dimensional object) consists of the set of all points in 3-space at a fixed distance r from a central point P. The solid enclosed by the sphere is called a ball (or, more precisely a 3-ball ).
An illustration from Jouffret's Traité élémentaire de géométrie à quatre dimensions.The book, which influenced Picasso, was given to him by Princet. New possibilities opened up by the concept of four-dimensional space (and difficulties involved in trying to visualize it) helped inspire many modern artists in the first half of the twentieth century.
The NMR structure of a UBA domain, among the most common types of ubiquitin-binding domain, from the protein ubiquilin-1 (top, cyan) bound to ubiquitin (bottom, orange). ). Isoleucine 44, the center of a hydrophobic patch on the ubiquitin surface that interacts with a number of ubiquitin-binding domains, is highlighted i
