MHB TikZ Challenge 3 - Vector Diagram

AI Thread Summary
The TikZ Challenge 3 invites participants to create impressive vector diagrams, focusing on geometric and physical representations. Submissions must be unique, with only one allowed per participant, and cannot be altered after posting. The use of the arrows and arrows.meta libraries is encouraged for enhanced arrow designs. Participants can seek advice on improving their diagrams, such as adjusting line thickness and incorporating colors. The thread will close for submissions in two weeks, followed by a two-week voting period to determine the best contribution.

Who can make the most impressive, interesting, or pretty TikZ picture?

This third challenge is to create a vector diagram.
Such as used in geometric figures, or in physical diagrams with forces and velocities, or in state diagrams.
For more impressive arrows, we might use the arrows tikz library, or the arrows.meta tikz library (its successor).
If it's not immediately obvious, please mention what makes your picture special.

Please post your submission in this thread.
This thread will be closed after 2 weeks.
After that we will have 2 weeks to vote on what we think is the best TikZ contribution for this challenge.

Only 1 submission of a picture is allowed, and it is not allowed to change the picture after submission.
Any change to the picture itself will disqualify it.
(That leaves some wiggling room for editing the description.)
See http://mathhelpboards.com/tikz-pictures-63/tikz-announcement-22140.html for more information on how to create and post TikZ pictures.
To help create pictures we can use this http://35.164.211.156/tikz/tikzlive.html.
See the TikZ and PGF Manual for more details on the possibilities of TikZ.

\begin{tikzpicture}[scale=3]
\coordinate (v1) at (0,0);
\coordinate (v2) at (1,1);
\coordinate (v3) at (0,2.5);

\draw[->] (v1) -- node
{$\vec{B}$} (v2);
\draw[->] (v2) -- node
{$\vec{H}$} (v3);
\draw[->] (v1) -- node
{$\vec{M}$} (v3);

\end{tikzpicture}

Ok in the spirit of submitting something this is my first time using TikZ. I'm not at all familiar with the syntax so had to use a template from elsewhere. I guess this is my "Hello, world!". Can anyone figure how to sweeten the picture? Maybe thicker lines, colors and better arrows? :)​
 
Hey Jameson, thank you for your contribution!

To answer your questions, we can add [thick] or [ultra thick] between square brackets to make the lines thicker.
And we can add [>=stealth] to get better arrows.
Doing this globally (within the first set of square brackets) we get:
\begin{tikzpicture}[scale=3, ultra thick, >=stealth]
\coordinate (v1) at (0,0);
\coordinate (v2) at (1,1);
\coordinate (v3) at (0,2.5);

\draw[->] (v1) -- node
{$\vec{B}$} (v2);
\draw[->] (v2) -- node
{$\vec{H}$} (v3);
\draw[->] (v1) -- node
{$\vec{M}$} (v3);
\end{tikzpicture}
Since the arrow heads are overlapping, we can shorten the arrows with [shorten >=3pt].
\begin{tikzpicture}[scale=3, ultra thick, >=stealth, shorten >=3pt]
\coordinate (v1) at (0,0);
\coordinate (v2) at (1,1);
\coordinate (v3) at (0,2.5);

\draw[->] (v1) -- node
{$\vec{B}$} (v2);
\draw[->] (v2) -- node
{$\vec{H}$} (v3);
\draw[->] (v1) -- node
{$\vec{M}$} (v3);
\end{tikzpicture}
To get even better arrows, and have more control, we can add '\usetikzlibrary{arrows}' or its successor '\usetikzlibrary{arrows.meta}' and use more dedicated directives.
See chapter 16 in the latest TikZ and PGF manual.
Oh, and for colors, we can add the name of a color in square brackets, such as [blue]. The manual also explains how to get more subtle colors.​
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
