### How sound is represented in a graph?

Let me imagine that air nearby has structure like this, meaning that pressure variation without any disturbance is almost equal. Now if I speak, I set some molecules of it in motion. They move with a ...

### Visualization of axisymmetric flows

This question might be vague but I want to get a feeling for axisymmetric flows. In mathematics a vector field $v=v(r,\theta,z)$ where $(r,\theta,z)$ are cylindrical coordinates is axisymmetric if it ...

### Using repelling and attracting forces, how to achieve a grid/square layout of nodes instead of triangular layout

I am trying to figure out what kind of forces, however artificial, would result in a layout of objects in a grid: I am trying to use d3 to draw grids - there may be more than one solution. I ...

### Visualizing the conformal compactification diagram of $G$

I asked a question a year and 3 months ago on mathstackexchange but after 3 bounties and still no answer I've decided to try here. Here's the link: conformal compactification. Construct a conformal ...

### Gravity and space bending question [duplicate]

Not a physicist here but something has been puzzling me for a while. As I understand gravity in General Relativity, it bends the space time as this Picture. Now this is all nice and elegant if I look ...

### Why are magnetic field lines imaginary?

There are many sources online which say that magnetic field lines are imaginary such as Toppr, Vedantu and CBSE Academic. I do know that magnetic fields are real and do exist. But when can we see ...

### General relativity in layman’s terms (doubt)

I’m a high school student. I was reading a PhD thesis by Rickard Jonsson about visualising general relativity. Fig. 2.11 explained the motion of an apple thrown up into the sky by saying that it’s not ...

### Visualisation tool for different speeds? [duplicate]

I'm a student often doing kinematics word problems with objects moving at X km/h, Y m/s, or Z cm/s. Yet, I have no idea what these units look like in real life. Out of curiosity, I'm searching for a ...

### What is good software for animating results?

I am a graduate student in physics and many times when I am working on something/playing around with some expressions I would like to visualize how it looks on the computer. I usually already know (...

### Relativistic rendering: ray tracing photon paths affected by masses

Given an initial photon position $p_{xyz}$ and its direction of travel $d_{xyz}$ a set of (point) masses, each with a location $m^i_{xyz}$ and mass $m^i_{m}$ a time step size $d$ how can I calculate ...

### Proton as viewed from an orbiting electron's perspective

When I see depictions of the electron orbital of a hydrogen atom, I see a static proton in the center surrounded by an electron cloud. What would it look like if we shifted the reference frame to the ...

### Can we represent 4D graphically? [closed]

Actually I know that axes are always perpendicular but after three axes we cannot draw any other axis that is perpendicular to all the other three axes. can any one say how can we draw another axes ...

### Terrell-Penrose effect and surface reflectance

All explanations of Terrell-Penrose effect seem imply that the effect makes some of the back-facing walls of a passing-by object visible. You can see some examples of those in many different ...

### Properties of orbit type diagrams

For fun, I created a 3d gravity simulation and colored each $(x,y)$ coordinate blue or green if a light mass put at that location would collide - within some number of simulation steps - with one of ...

### Visualization of object falling into black hole from the perspective of a distant observer

There exist a few relativistic renderings, even videos of this kind of event from the perspective of the infalling object, yet I have never seen the same event from the perspective of a distant ...

### Visualization of $n$-dimensional Hilbert spaces

I am learning quantum physics, and came across $n$-dimensional Hilbert spaces, is there any way one can visualize a $n$-dimensional space and the n components of the vectors existing in that space? P....

### Can many-particle wave functions be imagined in 3 dimensions - instead of $3N$ dimensions?

It is usually said that the wave function for $N$ particles cannot be imagined in 3 dimensions, but only in $3N$ dimensions. What is the exact argument? Is there a loophole? Schrödinger, Feynman and ... 53 views

### What does it mean to have a function of a field?

There was a Leonard Susskind lecture on the Higgs Boson I watched the other day, and he talked about graphing the field where the domain was some sort of field space. The lecture is here at about 6 ...

### How to visualize newtonian objects in term of harmonic oscillators?

From the group $U(1)$ in QED, via group representation we get the harmonic oscillators. However, I still have a hard time to imagine newtonian objects (computer, headphone, etc) as a combination of ...

### Energy eigenfunctions of a truncated harmonic oscillator-like potential

Assume a potential of the form \begin{eqnarray}V(x) &=& \frac{1}{2}m\omega^2x^2,~-x_0\leq x\leq x_0,\\&=& 0,\hspace{2.5cm}{\rm otherwise} \end{eqnarray} where $x_0$ is a finite ...

### With north and south poles fixed, do all geodesics have constant $\theta$ and $\phi$?

I was going thorough reading Kolb and Turner's The Early Universe where in Section 2.2 it starts by asking the following question. For a comoving observer with coordinates $(r_0,\theta_0,\phi_0)$, ...

### Pseudo-Riemannian 2D manifold (visualize time curvature)

My goal is to visualize somehow the curvature of time, as opposed to the curvature of space. I know that we generally talk about spacetime curvature altogether; however, the fact that spacetime has ...

### Is there a relation between this function and black holes?

I was fiddling with this complex function visualizer and accidentally found this function which looks a lot like the blackhole visualizations that I see on the net: $$f(z)=(z\bar{z}-1)^z$$ and I'm ...

### SPH - data visualisation in 3D

I'm not entirely sure this is the right place to ask this sort of question, but still. I have a problem with plotting 3D simulation data that I get with SPH. Basically, I want to be able to plot a '...

### How to visualize the angular frequency in SHM?

Can anyone define how can i visualize the angular frequency(ω) in a SHM y(t)=R sin(ωt+ϕ) (where ω=2π/T).Bcoz we can visualize frequency(f=1/T) as number of times the process is repeated in 1 sec so ...

### Visualizing higher dimension [duplicate]

Why can't we visualize Higher dimensions greater than 3? Is it just because the dimensions doesn't exist (Certainly I know that space-time is four dimensional) or any other physical reasons.

### Identifying "how far away" and "how big" things look to an observer in a given metric tensor's space

Let's say I have a 2D spatial slice $h$ of a metric $g$, i.e., the $x,y$-components of $g$, and that there is a person, Alice, facing a rod that is oriented perpendicularly to the direction that she ...
