In case you're wondering, the pitch you get from blowing into a wine bottle the way you'd play a flute is A 110, the second A below middle C. Based on a sample of 1.

+Kevin Coombes Thanks for the suggestion.

Most bottles are 750 ml, and I imagine that volume is the most important term in predicting the pitch, though shape probably makes some difference.

If I follow through with this research, maybe I can get an ignoble prize.

Whether we should do a few large studies or lots of small studies depends on what we believe is out there to be found.

+John Cook Good point. But I guess that's why we love LaTeX so much... In some way you can do almost everything you want, be it in one way or another. ;)

The "Training Students to Extract Value from Big Data" workshop just ended, and I have to admit to being quite steamed at the attitudes expressed.   This workshop was funded by the NSF Big-Data initiative, but the money was given to the National Research Council's Statistics branch, not to the branch that handles CS.  As a result, although there were a few computer scientists there, the majority of attendees and speakers were statisticians.  Two of the speakers showed in their slides the same offensive Venn diagram, whose three components were Math/Stat, Domain Science, and "Hacking."  Machine learning was defined as the intersection between Math/Stat and "Hacking."   And the intersection between "Hacking" and Domain Science was labeled "danger area," as if a computer scientist should not attempt to interact with an application area without the wise guidance of a Statistician.  Another participant expressed the position that, granted Locality-Sensitive Hashing was an intellectually interesting and useful idea, it must therefore be a branch of machine learning.  Yet another Statistician mentioned that he chairs a committee of the American Statistical Association to define a curriculum in "Data Science," and he saw no reason why SQL should be a part of this program.   I could go on, but I think I just calmed down a little.  Thanks for reading this.

Somehow, I just can't get excited by these arguments.

Introduction
I use math and computing to solve problems.

I have worked as a professor, programmer, consultant, manager, and statistician. I enjoy combining these skills and experiences to solve problems and see the solutions carried out.
