A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since ancient times on walls of caves, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface. The word graph is sometimes used as a synonym for diagram.
This is Feynman diagram of annihilation I get from wikipedia
https://en.wikipedia.org/wiki/Annihilation
I don't understand what the middle line with arrow to the right is. If I consider the left vertex and conservation of charge, it means the horizontal line with arrow to the right should carry...
Working on an art project using Feynman diagrams ... I'm curious if there are any that you consider to be particularly relevant to everyday human experience or particularly beautiful (according to any criteria you wish). Thanks!
I have trouble understanding the diagram and the answer key.
1) I am thinking time is the horizontal axis. Since A is π+, the quark composition will be ##u## and ##\bar{d}##. There are 2 vertices, let say P (on the left) and Q (on the right). I don't understand the conservation of charge at...
It has been shown in the text that ##h_0 = \frac 1 {\Box} J## with the diagram
and that ##h_1 = \lambda \frac 1 {\Box} (h_0 h_0) = \lambda \frac 1 {\Box} [( \frac 1 {\Box} J)( \frac 1 {\Box}J)]## with the diagram
I was not sure if the next order diagram is
or rather
Thus, I substitute...

For the problem with the diagram, I'm getting from n=4 to n=2, n=5 to n=4, n=5 to n=1 and n=4 to n=1. n=4 to n=2 corresponds to n=1 to n=2 in well C; n=5 to n=4 corresponds to n=1 to n=2 in well D; n=5 to n=1 corresponds to n=1 to n=3 in well D and n=4 to n=1 corresponds to n=1 to n=2 in well E...
I tried to construct a diagram, but to no avail, since I don't really understand the qn. However, my professor provided me with this graphical depiction (that i obviously don't understand)
The problem is actually a solved example
My attention is focused in understanding the displacement vector diagram as it has to deal with question (iv).
I have no problem understanding the velocity vector sketch below:
As you can see ND is the velocity of the river current due East and NE is...
I have my own thoughts and possible could provide sketch or instance use case, elaborate using evident setsettings. But I don't want to persuade, influence or lead other people who are actually educated and inadvertently guide and ultimately hinder the outcomes of their initial assessment.

This model diagram is possible when index0/index1=index1/index2=radius2/radius1 for the model's variables. 30 degree wave into a sphere. Reminded me of something out of that old science fiction movie, The Day the Earth Stood Still...
Hoping someone can chip in and help me understand a problem when it comes to two-force members.
I have a structure as shown below. Essentially its a single body attached at 3 points with pin joints. My question is, is it appropriate to treat each of the left and right side as individual...
I've read that the refraction of light at the boundary of a medium can be described as follows:
-a line of connected people marching. one side of the line enters mud, and slows down. This causes the non-mud side to pivot towards the slower side, which then causes the line to change direction...

circuitry. The current, I, to the oven's heating element is fed from a
voltage-controlled power amplifier such that I = EK1. A voltage, VD, derived
from a potentiometer, sets the desired oven temperature, TD. The oven...
The Minkowski spacetime in 3+1 dimensions does not have a boundary. Yet, its conformal diagram (see the left diagram in the attached picture) has a timelike boundary ##r=0##. A spacetime with a timelike boundary (another example is AdS) has a different causal structure than a spacetime without a...
I was able to solve b) but I am confused for a). I understand that in the proton-antiproton collision, only two quarks (one from proton and other from anti-proton) can be combined to get a virtual photon that in turn creates muon and anti-muon. I don't understand what would happen to the other...
Hello all, I am currently studying for a physics a-level qualification in the UK, I use the AQA specification and I am having trouble understanding this image representing a scenario I found in my textbook. The first image in the three part diagram shows this rotating coil and to me, it makes...
In the solution below it says 22% goes to 0.0309keV. From the diagram above I interpret 22% goes to 0.1298keV with EC(L)/EC(K)=3.0 and not 4.4. Why is that wrong ?
Thanks alot!

Suppose you are given the following requirements for a simple database for the National Hockey League (NHL):
1) the NHL has many teams,
2) each team has a name, a city, a coach, a captain, and a set of players.
3) each player belongs to only one team,
4) each player has a name, a position...
I think ##X## appears to be ##\pi^{+}## because it is light and energetically more favourable. Pion should be positive to ensure charge conservation. I am stuck at drawing a Feynman diagram for $$p+\bar{p} \to W^- + \pi^+$$.
Is this correct? Is this the leading order diagram or is there a...
The embedding diagram is well known for its qualitative representation of how the stress energy tensor curve the spacetime. We can construct a map from a general spherical metric to a cylindrical metric if we want to construct such diagrams.
Now, my confusion is if there exist curves out of the...

The answer is (B) but I don't understand why (C) is wrong. The force acting on the hinge has two components, horizontal and vertical. The horizontal component must be to the right to balance the horizontal component of tension but the vertical component can be either upwards or downwards. Wow to...
I'm looking to create a little webapp where the user can see the 3-D PVT phase diagram, giving the user functionality like orbiting the surface and moving a point along the surface. (I attached an image of the surface I'm referring to). To do that, though, I would need the data defining the PVT...
Hi , I asked in the general forum and it was suggested to ask this here, hoping someone can help. I made this diagram to depict the two answers, I'm looking for. Answer B is dependent on answer A. Thanks so any that can help :)

I am mostly focused on parts (b) and (d), which I typed out. For (b), I can tell the first pair of graphs is a sequential reaction (when Cysteine is saturated), but it appears ping-pong for the others because the slopes are roughly parallel. I know sequential has to reactants binding (so I...
Gamma is a Minkowski spacetime diagram generator. I probably started this project in August and have been working on it almost full-time since. It will be a free, open-source application.
The program can draw all the usual things: axes, grids events, and worldlines, etc.
It's easy to create...
