Wolfram Alpha Weekend

Ok, Wolfram Alpha is not entirely intuitive and it doesn’t have drill down to local USA level data as far as I can tell yet. When I selected “Median Income Illinois” it has an answer, but when I do “Median Income by state” it thinks state is a the chemical property. Also it doesn’t link up with wolfram’s mathworld as much as I was hoping: hence an entry on gini index, with a list by country, but no mathworld definition. Also no Buffon’s Needle!.

Some stuff I’ve enjoyed searching.

The finance is out of control. Black Scholes has about every greek derivative graph you could want for a option you put in. Grabbing a stock at random you can drill down into all kinds of financial fundamentals. Grabbing 4 stocks at random, you can get the mean-variance plot (!) and the correlation matrix between them (!!!) immediately.

gcd 533715, 156400, 29325

8 pints beer + 2 shots whiskey + large pizza. Related, how many shots in a bottle of booze? (Their unit conversion software is pretty top notch.)

Graph Theory. Click on the equals signs to activate any of those searches.

exp( -(x^2+y^2)). 3-d plot!

Also SAT score distributions but no ACT score distribution? C’mon! This thing was developed in the midwest.
