## What are inter-disciplinary and atypical uses for math MSc?

I have just completed my MSc in mathematics in Europe. I do enjoy math, but I spent my uni years feeling like a autodidact hippie marooned on an island full of Mr and Mrs I-Want-A-Good-Job. My main interests revolve around humanities (literature/history/anthropology) and economics (but not finance), and instead of starting a "stable" well-paying career I dream about something inter-disciplinary. I am very open to earning little money and relocating just to do kind of work that engages those skills. What are some random uses of my degree?

## Find standard deviation in Excel, but first develop a labor-saving trick

Help me with statistics and Excel. Especially help me if you know any labor saving methods. I want the median, mean and standard deviation for the average price of all items sold, but my spreadsheet-full-of-data doesn't tell me the price of each sale -- just the average price per store, and the number sold at that store. Something like this:

## Economics for Mathematicians

Economics Mathematics: I have a Maths degree but lately I've become interested in Economics (Microeconomics and Macroeconomics) and have been reading some textbooks and classic texts and doing some online lecture courses on Economics. But find many of that the "handwaving" graphical "proofs" of economic theories lack a sense of mathematical robustness. Do more thorough mathematics for these ideas exist? Where can I find them?

## Obama assassination : 1 in 55?

Does the fact that the betting markets still give Hillary Clinton a 1 in 55 chance of being President in 2008, mean that that is a reasonable estimate of the chance that Obama is assassinated before the election? What else could justify those odds now?

## SVM, HMM, and wavelets in bioinformatics

I'd like to learn about SVM, HMM and wavelet algorithms in their usage in bioinformatics. I have a somewhat rudimentary understanding of the underlying mathematics from Wikipedia and a couple other sources, but I find that a concrete demonstration of their application fleshes it out. Are there texts, software packages (preferably free) or papers you'd recommend that: 1) includes good starter problem sets, or; 2) demonstrates how these techniques are used in research applications (beyond "we used xyz here"). Thanks!

## What's the methodology for conducting national political polls in the US?

Are national political polls that make use of random sample populations adjusted to account for the differences in overall population distribution throughout the US (in other words, do national political pollsters typically use some methodology to appropriately weigh responses from poll respondents depending on whether they live in more densely or less densely populated regions)?
