Seven Y's

Seven Ys (not wyes) in the freight yard, not including those that are upside down.

Is Greenland the greatest country in the history of the world. You learn something new every day

Yikes! Diatribes about The Evil Math are not encouraged, as any mentioning of that subject gives me a headache. Methinks this was known beforehand and deliberately ignored. Those living in Canada are known to exhibit such behavior as a result of their being jealous of living next to The Greatest Country in the History of the World. By the way, my slide rule abacus just came back from its monthly calibration and is in fine working order.

Your slide rule abacus needs to be multilingual as the 'upside down' letters you refer to are actually the Greek letter ' lambda', as everyone knows, or at least those of use with a high school diploma ;
In mathematical logic, lambda calculus, also written as λ-calculus, is a formal system for function definition, function application and recursion. It is used in the investigation of problems in computability or recursion theory, and forms the basis of a paradigm of computer programming called functional programming.[1]

In the lambda calculus, functions are first-class entities: they are passed as arguments, and returned as results. Thus lambda expressions are a reification of the concept of an unnamed procedure without side effects. The lambda calculus can be thought of as an idealized, minimalistic programming language. It is capable of expressing any algorithm, and it is this fact that makes the model of functional programming an important one. Functional programs are stateless and deal exclusively with functions that accept and return data (including other functions), but they produce no side effects in 'state' and thus make no alterations to incoming data. Modern functional languages, building on the lambda calculus, include Erlang, Haskell, Lisp, ML, and Scheme, as well as nascent languages like Clojure, F#, Nemerle, and Scala.

The lambda calculus continues to play an important role in mathematical foundations, through the Curry-Howard correspondence. However, as a naïve foundation for mathematics, the untyped lambda calculus is unable to avoid set-theoretic paradoxes (see the Kleene-Rosser paradox).(Copyright Wikipedia)

Yakima makes 8, or is it 10?
Dave Beedon06-Jul-2006 21:32
Exactly as stated in the description, but Y?
Guest 06-Jul-2006 10:28
There were 9 y's Dave! (in my intellectually challenged post!)

I see seven switches angling to the right and two to the left (upside down). Does my slide rule abacus need adjustment?

Count the number of "Y"s in Dan dunn's first comment, refer back to your title, check for discrepancies.
Numerically challenged is a facetious term for someone whose abilty to comprehend basic maths is slightly under par.
Dave Beedon27-Jun-2006 21:48
John, I confess ignorance: what did you mean by "numerically challenged"?
John Cooper27-Jun-2006 21:45
That was such a good point I had to repeat it.
John Cooper27-Jun-2006 21:43
Numerically challenged.
John Cooper27-Jun-2006 20:04
Numerically challenged.

Dave! I hope you don't think I was being a "Wise Guy" DD
