Visualization Definition and 89 Threads

Visualization or visualisation (see spelling differences) is any technique for creating images, diagrams, or animations to communicate a message. Visualization through visual imagery has been an effective way to communicate both abstract and concrete ideas since the dawn of humanity. Examples from history include cave paintings, Egyptian hieroglyphs, Greek geometry, and Leonardo da Vinci's revolutionary methods of technical drawing for engineering and scientific purposes.
Visualization today has ever-expanding applications in science, education, engineering (e.g., product visualization), interactive multimedia, medicine, etc. Typical of a visualization application is the field of computer graphics. The invention of computer graphics (and 3D computer graphics) may be the most important development in visualization since the invention of central perspective in the Renaissance period. The development of animation also helped advance visualization.

    I A way to comprehend the geometry of a hypercube

    It's extremely hard, if not outright impossible, for our limited brain to visualize 4D objects. 3D objects are fine, but 4D is just impossible (except, maybe, to some people). However, at one point I figured out a way to comprehend (in some ways "visualize") the 4-dimensional hypercube, which...

    Drawing diagrams in physics is so difficult for me!

    TL;DR Summary: I have a hard time doing well in physics questions from my undergraduate course. The reason for this is because I don't understand how to draw the motions of the objects in diagrams. Basically, I'm terrible at diagram making and visualisation of events that occur within a physics...

    B Very basic questions about visualizing spacetime

    I'd like to start with: Does the rubber sheet analogy still hold true enough? Or is there really no visualization (it's all mathematical constructs)? Does this picture analogy hold at all here? With the curved geodesics influencing the paths of things. Thanks!
