Jesus' favorite prayer

Source (Mark 12:29)

One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him, “Of all the commandments, which is the most important?”
“The most important one,” answered Jesus, “is this: ‘Hear, O Israel: The Lord our God, the Lord is one.[﻿

Who says Math ≠ Fun?﻿
The Evolution of Math Teaching
1960s: A peasant sells a bag of potatoes for \$10. His costs amount to 4/5 of his selling price. What is his profit?
1970s: A farmer sells a bag of potatoes for \$10. His costs amount to 4/5 of his selling price, that is, \$8. What is his profit?
1970s (new math): A farmer exchanges a set P of potatoes with set M of money. The cardinality of the set M is equal to 10, and each element of M is worth \$1. Draw ten big dots representing the elements of M. The set C of production costs is composed of two big dots less than the set M. Represent C as a subset of M and give the answer to the question: What is the cardinality of the set of profits?
1980s: A farmer sells a bag of potatoes for \$10. His production costs are \$8, and his profit is \$2. Underline the word "potatoes" and discuss with your classmates.
1990s: A farmer sells a bag of potatoes for \$10. His or her production costs are 0.80 of his or her revenue. On your calculator, graph revenue vs. costs. Run the POTATO program to determine the profit. Discuss the result with students in your group. Write a brief essay that analyzes this example in the real world of economics.

Alright, Tea Party, you win, let's drop Obamacare and fund the Affordable Care Act instead.   Polls have definitely shown that more people favor the ACA.

Even Fox News likes Obamacare
Let me see if I understand this.  To become a Glass Explorer you must write in 50 words or less why you should be part of the Project.  If chosen, you will pay \$1500 plus tax and attend a special pick-up experience, in person, in New York, San Francisco or Los Angeles, at your own expense.  If chosen, you perform some interesting activity, again, at your own expense, and up load the video to the Project.  The created video becomes the property of the Project and any profits made from the sale the the glasses and/or the videos created are also the property of the Project.  Please explain why anyone would do this, and do not say "For the experience".﻿

Seeking Glass Explorers: goo.gl/PbKWr

Last year we showed Glass to the world for the first time - we jumped out of airships, crashed New York Fashion Week and even took a ride on the subway. It’s been an exhilarating journey so far and there’s a lot more to come, but we can’t go it alone. We’re developing new technology that is designed to be unobtrusive and liberating, and so far we’ve only scratched the surface of the true potential of Glass.

Now we want you to get involved and that’s why today we’re expanding our Glass Explorer Program. We’re looking for bold, creative individuals who want to join us and be a part of shaping the future of Glass. Glass is still in the early stages, so we expect there will be some twists and turns along the way. While we can’t promise everything will be perfect, we can promise it will be exciting.

We’d love to make everyone a Glass Explorer, but we’re starting a bit smaller. So, if you want to be one of the first Explorers, go to www.google.com/glass/start/how-to-get-one to find out how.
