In high school, when we got our first Casio pocket calculators, we used to play this game where we would punch "1" "+" "+" and then "=" a hundred times as fast as we could to make the display count up to 101. We called it the hundred meter dash. It was a humbling experience that none of us could do it in less than ten seconds (the fastest one, a drummer in a band, did it in about 12 seconds), so we were slower tapping a finger than the fastest athletes racing the hundred meters. Maybe I should've kept the calculator and tried it again later...

You include a placebo as a control for the treatment. When testing placebo, you need to include a control such as non-treatment and perhaps some meditation or something like that.

Turing trade looks like a scam to me. Nowhere do I see any identification of who is behind it. I suspect that anyone who enters their credit card information or whatever to make trades there is asking for trouble.

I guess there are exceptions to the diminishing returns to tapping. At 46 I'm still as tap-happy as I was 30 years ago. Speed's still there and, most enjoyably, a well- developed rhythmic use of all 8 fingers (I leave the pinkies out), while my feet serve as bass drums.
Also, within the past year, and with some diligent practice, I've been able to fiddle and clog together. For a total waste of time, see

I do not know this to be true, but it appears to be a project of a student, or alumnus of the duke computer science department. A phone number and possible home address are available if one knows where to look.

Click on "What is Turing trade?"

A Turing machine is a simple computer which can be proved to be equivalent to any computer. This is unrelated to the Turing test, which is the attempt to distinguish between man and computer via text conversation. Thus item #4 should read "betting on the Turing test."

Too bad it's not a site for betting on whether Turing machines will halt.

A Turing machine is a model of computation at least as powerful as any other known model (in terms of computability). It is unrelated to the Turing test, which is what this site is based on, apart from their being both named after Alan Turing.

Thank you Mark, Peter and Andy, I came here to say exactly the same thing. I was wondering how the heck one would bet on Turing machines.

Damn, and here I was hoping that prediction markets had been shown to solve the halting problem.
"Turing tests" not "Turing machines".
