Testing some JS bloat

Coulomb's law

$$F=\frac{Q_a Q_b}{r^2}\cdot\frac{1}{4\pi\epsilon_0\epsilon_r}$$

Electric field

$$E=\frac{Q}{r^2}\cdot\frac{1}{4\pi\epsilon_0\epsilon_r} \Leftrightarrow F=E\cdot Q$$ $$W=\int P \,dt =\int F \,ds \Leftrightarrow U_{ab}=\int_a^b E\,ds$$

DC motor

Structure

First the induced Lorence force moves the stator sideways
The same happens at the other side so a moment arises, resulting in a clockwise rotation of the rotor.

Such a so-called DC motor is using the Lorence force to induce a Moment which turn the rotor inside the stator.
Inside the rotor are pairwise inserted copper wires which transport a current across it. This current crosses the magnetic field $\vec{B}$. This results in a force perpendicular towards $\vec{B}$ and the current $\vec{I}$.
The resulting force $\vec{F}$ can be described by the following cross product:

$$\vec{F}=\vec{I}\times\vec{B}$$

Right hand rule

A good example for a better understanding of the Lorence force is the so called "right-hand-rule". Take a look at your right hand. You don't even need all your fingers lol.
Your thumb points the direction of the flowing current $I$. Your index finger points towards the direction the magnetic field directs. And your third finger, which you move 90 degrees from your hand, is now the direction of the resulting force $F$. Pretty simple huh? $$Test$$

Why is bloat bad?

In times of huge leaps in processing power software gets more sluggish everyday
bloat is very bad
Why cant all Browser just support MathML? I mean its even a official part of the HTML5 standard...
