What is Visualization: Definition and 85 Discussions
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.
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...
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...
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!
I'm trying to picture a complex vector in my mind. A real vector is usually drawn as an arrow pointing in some direction in space and having a positive real magnitude "length". I'm trying to understand a complex vector the same way.
Is it drawn as an arrow pointing in some direction having a...

The FLRW metric has been introduced to characterize the homogeneity and isotropy of the Universe and accordingly to obtain "easy" manageable solutions in Friedmann equations.
The FLWR metric is

Does anyone have a clue what the gold points and associated lines represent?
I notice that all the gold lines form closed loops (so they're not travel paths) and they cross themselves (so they're not contours).
I can't think of any type of data that would result in this.
I've tried to follow...
If I had a nickel every time someone depicted curvature of space-time as a marble on rubber membrane I would have a lot of nickels however that description is not accurate; A channel called science clic has the most accurate visualization of bend of space-time I have ever seen however if anyone...
I'd love have a little discussion about the Interior Schwarzschild Solution.

Ispired by PeterDonis remark about "river model" in some thread a time ago I made next visualization picture.

Hi! First off, I'm just an upcoming junior in Civil Engineering, and I have little teaching experience. I have done well in engineering classes so far though, and I've thought about ways to improve how classes are taught. While there are some widgets for engineering, like those in MATHTAB and...
Summary:: Seeding and visualization techniques
Hi
I am looking for resources where I can learn the following:
Seeding strategies and algorithms for vector fields (texture-based, geometry, topological)
Different techniques for visualizing vector fields (streamlines, glyph-based, LIC etc)
I just finished my freshman year in computer engineering at my college, and after some physics and materials science classes I noticed a pattern. Everybody—at least in my class, I don't about the rest of the world—is just memorizing formulas, myself included. I'm really trying to not just...
Can someone provide me intuitive visualization of how E or H field can be longitudinal in a waveguide (TM/TE)? TEM is easy to visualize, but how EM wave can behave like sound in a waveguide (constant phase and amplitude plane in the same direction)?

I am collecting ways to visualize the curvature of spacetime -- and movement of objects affected by gravity -- as per Einstein's GR. Alternatives to the bowling ball / trampoline image so often used in the popular press. Images that show the similarities / differences between Newton & Einstein...
Are there any folks here who use open source alternatives to Matlab and Mathmatica for visualization of quantum mechanics?
Also, are you aware of any introductory quantum material for that tool?
If not, do you think such a thing would be worthwhile for visual leaners? Why or why not?
I have...
Hi All,
I would like to learn Tableau , but AFAIK, it is not available for free beyond a trial basis.
I have heard of BIRT https://en.wikipedia.org/wiki/BIRT_Project as a freeware substitute.
Has anyone tried it or heard something from people who have used it?
Thanks.

how can one visualize an idea of "instant distance". seems a bit abstract that at some time "t" we can evaluate "instant distance" by *speed(t)*dt". imagine a speed versus time graph.

A fluid visibly spinning clockwise doesn't necessarily have a net angular momentum. I figured that this might be the case by considering that the fluid rotations within might be counter-cyclical. It would appear that you could apply this relationship many-fold times, where a fluid consists of...
