Can I use my powers for good? "And they aren't open to hiring PhDs for entry level jobs (you are "overqualified")." Do you have any evidence to back this claim? A maths PhD I know got 4 job offers in entry-level finance, probably the in the top 5% in terms of success. |

Can I use my powers for good? How is insurance evil? We need mathematicians to price the extremely hard to price products that wouldn't exist without the talent. Insurance is incredible -- long-term disability insurance, life insurance, the positive impact of these products is far reaching. The evidence that statistical arbitrage is a net harm is not in yet. Some academics view automated market makers (at least) as liquidity providers without which a market can not even exist, and spread traders as aiding in instantaneous cross-asset price discovery. Sell-side quants can build products to help (e.g.)farmers reduce risk |

Why $\frac{1}{2i}(e^{i\omega t} - e^{-i\omega t}) = \frac{i}{2} (e^{-i \omega t} - e^{i\omega t})$ I get it now thanks guys. |

Is this geometric Brownian Motion? $\sigma(t)$ is stochastic and has a separate Wiener process inside of it. |

Partial Derivative of an Integral Do you know if/why my answer is incorrect (if yours is correct)? I know that it's false to say that "you can't write partial derivatives w.r.t. BM". For example apply Ito's lemma to the function $f(t,x)$, where $x$ is $B(t)$ (in fact this is one of the most standard routines in stochastic finance). Applying Ito's lemma you will end up having to evaluate $\frac{\partial f}{\partial x}(t,x)$. |
