Happy
Pi Day!
I'm
not quite sure how it started - probably something to do with the
husband and father being being a scientist who loves math - but we
are a family that celebrates the nerd holidays. The two biggies are
Pi Day, March 14 (3.14), and Mole Day, October 23 (1023).
There exists a myriad of others – Stars Wars Day (May 4, as in
“May the 4th be with you”), Tolkien Reading Day (March
25, commemorating the downfall of Sauron in The Lord of the Rings)
– I could go on and on - but March 14 and October 23 have always
been the big ones in our household, probably because there are
traditional foods associated with those days.
Pi,
or ϖ, is that mathematical
constant, 22/7, often expressed as the decimal, 3.14159..., the number
that represents the ratio of a circle's circumference to its
diameter. An irrational number, calculated to over one trillion
digits beyond its decimal point, never ending and never settling into
a permanent repeating pattern, it is affectionately “nicknamed”
3.14, hence its association with March 14. And on March 14 we
celebrate pi with pi(e). Yes, I was that mom who baked pies for high
school math classes...at my kids' request. Well, the kids are on
their own now (maybe at Baker's Squares somewhere today?), but I
couldn't let the day go by without acknowledging it in some way.
Below is one of my favorite pie recipes, and if the market has good
pears today, one that I will be baking for tonight...
Pear
Crumble Pie
6
medium Barlett pears
3
tablespoons lemon juice
½
cup sugar
2
tablespoons flour
1
teaspoon grated lemon peel (optional)
1
unbaked 9-inch pie crust
Crumble
Topping
Cut
and peel 5 pears. Sprinkle with lemon juice. Mix sugar, flour, and
lemon peel; stir in pear slices. Put into pastry shell. Cut
remaining pear into 6 – 8 neat slices. Arrange on top of pie in a
pinwheel pattern. Sprinkle with Crumble Topping. Bake at 400º for
45 minutes or till pears are tender. Serve warm.
Crumble
Topping:
Mix ½ up flour, ½ cup sugar ½ teaspoon ginger and ½ teaspoon
cinnamon, ¼ teaspoon mace or cloves. Cut in 4 tablespoons butter or
margarine until crumbly.
Enjoy!
And if I remember, come October 23, Mole Day (commemorating that
great basic measuring unit of chemistry, Avogadro's Number (6.02 x
1023), I'll share my recipe for mol(e)asses cookies...
...yep,
nerds...

Sorry, Pi is not 22/7ths. 22/7ths is a poor approximation of Pi. Irrational numbers cannot be exactly represented by any fraction, that's what irrational numbers are. 355/113 is a much better approximation, but still just an approximation.
ReplyDeleteYou are correct - 22/7 is a poor approximation. I should have referred to 22/7 and 3.14 both as "nicknames"...
