Yes, Pie! That's the word of the day, pie, and the topic for today's entry.

Pie, for those who don't know, is a dish of pastry containing either custard, cream, fruit or other sweet relish. Alternatively, pie as a main course or snack, rather than a dessert or a sweet snack, may be prepared with meat or cheese (quiche, pronounced kee-she, not quicky). As an expression, pie may be used to denote the whole of a pool, generally of money, e. g., "I want a piece of the pie".

Oh, what's that? Right. Check that, the word is Phi, not Pie. My bad...

Phi, which I asked my readers to clarify upon some weeks ago, is a number. If you remember correctly, my question is how is it defined as an irrational number. Today I'm glad, nay, proud to say I have an answer. Phi is half of the sum of one and the square root of five. That's (sqrt(5)+1)/2, if you'd rather see it in formula. This tidbit of knowledge was courtesy of my Algorithms professor. Kudos to him.

Wishing you well a very pleasent weekend, golden fairwells.

ArabianShark now leaves to pack. Yay, away for the weekend!
