Yup.

The probability of getting at least 2 heads on pennies and at least 4 tails on quarters after flipping 8 random coins drawn from a bag of 10 quarters and 6 pennies is:

${\displaystyle \sum _{k=2}^{4}{\frac {(16-k)!6!}{16!k!}}\times {\frac {k!}{2!(k-2)!2^{k}}}\times {\frac {(8-k)!}{4!((8-k)-4)!2^{8-k}}}}$

My middle name:

${\displaystyle \ \ i\hbar {\frac {\partial }{\partial t}}\Psi (\mathbf {r} ,\,t)=-{\frac {\hbar ^{2}}{2m}}\nabla ^{2}\Psi (\mathbf {r} ,\,t)+V(\mathbf {r} )\Psi (\mathbf {r} ,\,t)\ \ }$

Summation of the derivative of ln x.

${\displaystyle f(x)={\frac {d\left(\ln x\right)}{dx}}}$

${\displaystyle \sum _{x=1}^{\infty }f\left(x\right)}$

Also, I would like to point out that I am a huge nerd srsly and that one of my best friends, Korps Commander djbob Korps Commander djbob sage729, is the coolest person on the face of the planet. Yes sir, no one can surpass his coolness.
