Happy Pi Day 2013

Today is Pi Day.

Just what is Pi Day? Well since the value of Pi is considered to be 3.14 then today date of 3-14-13 is this year’s Pi Day.

The number Pi (or π, if you’re using the Greek letter) is a mathematical constant. It’s technically the ratio of any circle's circumference to its own diameter. For general use, Pi is the number you get when dividing 22 by 7. It’s approximately equal to 3.14159.
What’s special about Pi? Well here are a few interesting things:
  •  Pi is an irrational number. In irrational number is one that can’t be written exactly as a ratio of two integers. That means when people say Pi is just 22/7, they’re technically not correct. 

  •  Pi is a transcendental number, which means that despite thousands of years of people trying to do it, it is impossible to solve the ancient challenge of “squaring the circle.” It means using the tools of a compass and straight-edge to construct a square with the exact same area as a circle.

  •  Pi has a decimal pattern never repeats. So far, nobody has been able to distinguish a pattern of repeating numbers in the digits that flow to the right of the decimal point, despite having been calculated out to more than a million decimal places.
                Here’s an example: 3.14159265358979323846264338327950288419716.

As a vocational college, we find that most of our students are adults who use everyday math just fine but have forgotten some of the things they learned in secondary school. Geometry and the concept of Pi are concepts not only used in specialized fields but also around us all the time if you just look for them.

Events like today’s Pi Day are good reminders of how fun math can be and how to keep on learning.

And, since any celebration includes some type of dessert, here is an easy recipe for making your own Pi pie on Pi Day. Its measurements use the value of Pi and it includes Greek yogurt for the Greek letter. Ok, that might be stretching it some but we’ve got to get in the spirit of these things and it sure does make a good no-bake cheesecake pie.

EASY As PI - PI-Day Cheesecake Pie


3.14 ounces of plain Greek yogurt (can be rounded to 3 ounces)

3.14 ounces of sugar

6.28 ounces cream cheese, softened (can be rounded to 6 ounces)

6.28 ounces of thawed whipped topping (can be rounded to 6 ounces)

3.14 ounces of sugar (can be rounded to 3 ounces)

Splash of vanilla


Mix cream cheese, yogurt, and sugar together until smooth. Add vanilla. Gently fold in whipped topping until well combined. Do not over-mix or the air will come out of the whipped topping and the pie will be too dense. Pour into pie crust shape (see below for recipe). Chill for 1 hour in refrigerator and serve. Top with remaining whipped topping if desired.

Make Your Own Graham Cracker Pie Crust


2 cups graham cracker crumbs

1/2 cup butter

1/3 cup brown sugar

1/2 teaspoon cinnamon


Preheat oven to 400 degrees

Using heavy duty aluminum foil, pinch out the PI Greek letter π to form at least 1 inch wide “legs” and 1 inch wide top bar. The lengths should be approximately four inches each. Spray well with nonstick cooking spray.

Combine all ingredients.

Press over bottom and up sides of foil form. Chill for half an hour, using crumpled aluminum foil around the form to support the shape until it sets. Bake at 400° for 10 minutes.

Hostess Workers Get Retraining

According to a US Department of Labor news release, 18,000 former Hostess workers (the makers of Twinkies and Ding Dongs) are now eligible to apply for Trade Adjustment Assistance (TAA) training funding.

The federal TAA program, created in 1974, provides support to those workers who lost their jobs due to foreign trade.  To allow Hostess workers to receive this benefit, the Department of Labor had to determine whether the big layoff event that occurred in January (and caused a run in grocery stores for the snack foods) met the eligibility criteria spelled out in the Trade Act of 1974. The department’s investigation found that increased imports of baked products from other countries contributed to the company's sales declines and workers losing their jobs.  As a result, the TAA eligibility was granted to Hostess workers in 48 states, including the Hostess bakery stores in Modesto and Turlock.

The TAA eligible workers were engaged in activities related to the production, distribution and sale of baked goods such as bread, buns, rolls, snack cakes, doughnuts, sweet rolls and similar products.

 As part of the rules, the TAA program can be implemented if the federal Department of Labor finds that a significant number of workers at the company age 50 or over possess skills that are not easily transferable and that competitive conditions within the industry are adverse.

What do they get?

Those who qualify may receive case management and re-employment services, training in new occupational skills and/or trade readjustment allowances that provide income support for workers enrolled in training. Workers may also receive job search and relocation allowances, and the Health Coverage Tax Credit.

There are three different tracks an unemployed person under the TAA may follow:

1) Occupational Skills or Vocational Training

•Often offered through a  technical college: this includes college-level degrees or certificate programs along with necessary prerequisite courses through a TAA eligible training provider.

•Apprenticeship programs and skill focus training.

2) Remedial Education

•Remedial Education includes Adult Basic Education often in areas of math, English or reading skills, obtaining a High School equivalency credential (GED or HSED), or pursing a program titled English as a Second Language (or ESL) classes

3) Employer Based Training or On-The-Job (OJT) Training

•Contracts can be established between an employer and the participant of the TAA program to provide for training to take place at the employer site, for a set period of time. Payment is made to the employer to reimburse them for the cost they incur to provide training for their job openings.

While TAA is open to eligible workers of all ages, workers 50 years of age and older may elect to receive Re-employment Trade Adjustment Assistance instead. If a worker obtains new employment at wages less than $50,000 and less than those earned in the trade-impacted employment, the RTAA program will pay 50 percent of the difference between the old wage and the new wage, up to $10,000 over a two-year period. RTAA participants may also be eligible for retraining and the HCTC.

TAA can provide fully funded training, a health coverage subsidy, extended income support, and other benefits to dislocated workers whose companies move production or outsource to another country, or are forced to lay off workers or close plants due to increased imports and foreign competition.

Community Business College has trained students eligible for TAA assistance but usually as a result of manufacturers who moved their plants to other countries.

By the way, the snacks for which they were famous might be making a comeback as the remnants of the Hostess company announced in February that they are close to selling their Wonder Bread brand to Flowers Foods. Can the resurrection of Twinkies be far behind?
