Click the expression below to see several definitions of pi:
$π = 3.14159265358 ... π = 2 i Log \frac{1 - i}{1 + i} π = 2 \frac{2}{\sqrt{2}} \frac{2}{\sqrt{2 + \sqrt{2}}} \frac{2}{\sqrt{2 + \sqrt{2 + \sqrt{2}}}} ... \frac{π}{4} = \frac{1}{2 + \frac{1^{2}}{2 + \frac{3^{2}}{2 + \frac{5^{2}}{2 + \frac{7^{2}}{2 + ...}}}}}$

Thomson scattering theory

$\begin{matrix} \frac{d^{2} P}{d Ω_{s} d ω_{s}} & = & r_{e}^{2} \int_{V} < S_{i} > d^{3} r \int {| \hat{e} . \overset{\leftrightarrow}{Π} . \hat{e} |}^{2} κ^{2} f δ (k . v - ω) d^{3} v \\ = & r_{e}^{2} \int_{V} < S_{i} > d^{3} r \int {| 1 - \frac{(1 - \hat{s} . \hat{ı})}{(1 - β_{i}) (1 - β_{s})} β_{e}^{2} |}^{2} {| \frac{1 - β_{i}}{1 - β_{s}} |}^{2} \\ \times (1 - β^{2}) f δ (k . v - ω) d^{3} v \end{matrix}$

Maxwell's Equations

${\begin{array}{rcl} \nabla \times \vec{B} - \frac{1}{c} \frac{\partial \vec{E}}{\partial t} & = & \frac{4 π}{c} \vec{j} \\ \nabla ċ \vec{E} & = & 4 π ρ \\ \nabla \times \vec{E} + \frac{1}{c} \frac{\partial \vec{B}}{\partial t} & = & \vec{0} \\ \nabla ċ \vec{B} & = & 0 \end{array}$

Einstein's field equations

$R_{μ ν} - \frac{1}{2} g_{μ ν} R = \frac{8 π G}{c^{4}} T_{μ ν}$
