memetic engineering desu

CHOO CHOO MOTHERFUCKER

>>7695054
How do you make memes energy efficient /Sci/?

>>7695022
Because it's not a meme engineering field filled with fuckboys, betas, autists, chinks, curries, and SJWs whining about muh soggy knees.

Nah, rocks son.

rock on

Is it possible to major in goat engineering?

Easy shit anon.

Let <span class="math">{\gamma _{\alpha \beta }} = {\partial _\alpha }X \bullet {\partial _\beta }X[/spoiler]

Then...

<span class="math">
\frac{{\delta S}}{{\delta {h^{\alpha \beta }}}} = \frac{{ - T}}{2}\int {{d^2}\sigma \frac{{\delta \left( {\sqrt { - h} {h^{\alpha \beta }}{\gamma _{\alpha \beta }}} \right)}}{{\delta {h^{\alpha \beta }}}} = 0}
[/spoiler]

<span class="math">\delta \left( {\sqrt { - h} {h^{\alpha \beta }}{\gamma _{\alpha \beta }}} \right) = \delta \left( {\sqrt { - h} } \right){h^{\alpha \beta }}{\gamma _{\alpha \beta }} + \delta \left( {{h^{\alpha \beta }}} \right)\sqrt { - h} {\gamma _{\alpha \beta }} + \delta \left( {{\gamma _{\alpha \beta }}} \right)\sqrt { - h} {h^{\alpha \beta }}[/spoiler]

<span class="math">
\delta \left( {\sqrt { - h} } \right) = \frac{{\delta ( - h)}}{{2\sqrt { - h} }} = - \frac{1}{2}\sqrt { - h} {h_{\alpha \beta }}\delta ({h^{\alpha \beta }})
[/spoiler]

<span class="math">
\frac{{\delta \left( {\sqrt { - h} {h^{\alpha \beta }}{\gamma _{\alpha \beta }}} \right)}}{{\delta {h^{\alpha \beta }}}} = - \frac{1}{2}\sqrt { - h} {h_{\alpha \beta }}{h^{\rho \omega }}{\gamma _{\rho \omega }} + \sqrt { - h} {\gamma _{\alpha \beta }} = 0
[/spoiler]

And the equation of motion is...

<span class="math">
{\gamma _{\alpha \beta }} = \frac{1}{2}{h_{\alpha \beta }}{h^{\rho \omega }}{\gamma _{\rho \omega }}
