"The whole people must take upon themselves the education of the whole people and be willing to bear the expenses of it. There should not be a district of one mile square, without a school in it, not founded by a charitable individual, but maintained at the public expense of the people themselves." -- John Adams

"No money shall be drawn from the treasury, for the benefit of any religious or theological institution." -- Indiana Constitution Article 1, Section 6.

"...no man shall be compelled to frequent or support any religious worship, place, or ministry whatsoever, nor shall be enforced, restrained, molested, or burthened in his body or goods, nor shall otherwise suffer on account of his religious opinions or belief; but that all men shall be free to profess, and by argument to maintain, their opinion in matters of religion, and that the same shall in no wise diminish enlarge, or affect their civil capacities." – Thomas Jefferson

Hard Times Ahead for the American People – Einstein

Today, March 14 is Pi day (3.14) and the birthday (#138) of Albert Einstein.

Einstein came to the U.S. because,
...the rise of the Nazi party and anti-Semitism made it increasingly difficult for him to work and in 1932 he took up the offer of a post at Princeton. He became a citizen of the United States, but retained Swiss citizenship.
The quotes below are from Wikiquote.


ON FACTS AND THINKING

Einstein couldn't remember the speed of sound. This response to someone who questioned that is an argument in favor of learning how to learn instead of rote memorization. Intelligence, after all, is know what to do when you don't know what to do.
[I do not] carry such information in my mind since it is readily available in books. ...The value of a college education is not the learning of many facts but the training of the mind to think.

ON BALANCE
If A is success in life, then A = x + y + z. Work is x, play is y and z is keeping your mouth shut.

ON INTUITION AND INSPIRATION
I believe in intuition and inspiration. … At times I feel certain I am right while not knowing the reason. When the eclipse of 1919 confirmed my intuition, I was not in the least surprised. In fact I would have been astonished had it turned out otherwise. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.


ON USING MATH

In a letter to a high school student, Einstein wrote,
Do not worry about your difficulties in Mathematics. I can assure you mine are still greater.

ON POLITICS

Einstein's response to, "Dr. Einstein, why is it that when the mind of man has stretched so far as to discover the structure of the atom we have been unable to devise the political means to keep the atom from destroying us?”
That is simple, my friend. It is because Politics is more difficult than physics.


ON THE POWER OF ONE PERSON
A man's value to the community depends primarily on how far his feelings, thoughts, and actions are directed towards promoting the good of his fellows. We call him good or bad according to how he stands in this matter. It looks at first sight as if our estimate of a man depended entirely on his social qualities.

And yet such an attitude would be wrong. It is clear that all the valuable things, material, spiritual, and moral, which we receive from society can be traced back through countless generations to certain creative individuals. The use of fire, the cultivation of edible plants, the steam engine — each was discovered by one man.

Only the individual can think, and thereby create new values for society — nay, even set up new moral standards to which the life of the community conforms. Without creative, independently thinking and judging personalities the upward development of society is as unthinkable as the development of the individual personality without the nourishing soil of the community.

The health of society thus depends quite as much on the independence of the individuals composing it as on their close political cohesion.

ON SURVIVING TYRANNY

The Einsteinian equivalent of Martin Niemöller's poem.
Zionism gave the German Jews no great protection against annihilation. But it did give the survivors the inner strength to endure the debacle with dignity and without losing their healthy self respect. Keep in mind that perhaps a similar fate could be lying in wait for your children.


ON WISDOM
Wisdom is not a product of schooling but of the lifelong attempt to acquire it.

ON LEARNING, TEACHERS, AND EDUCATION

Einstein's experience reinforces the fact that relationships in education are as important as the content.
School failed me, and I failed the school. It bored me. The teachers behaved like Feldwebel (sergeants). I wanted to learn what I wanted to know, but they wanted me to learn for the exam. What I hated most was the competitive system there, and especially sports. Because of this, I wasn't worth anything, and several times they suggested I leave. This was a Catholic School in Munich. I felt that my thirst for knowledge was being strangled by my teachers; grades were their only measurement. How can a teacher understand youth with such a system? . . . from the age of twelve I began to suspect authority and distrust teachers. I learned mostly at home, first from my uncle and then from a student who came to eat with us once a week. He would give me books on physics and astronomy. The more I read, the more puzzled I was by the order of the universe and the disorder of the human mind, by the scientists who didn't agree on the how, the when, or the why of creation. Then one day this student brought me Kant's Critique of Pure Reason. Reading Kant, I began to suspect everything I was taught. I no longer believed in the known God of the Bible, but rather in the mysterious God expressed in nature.

ON AMERICA

Einstein's foresight, sixty-eight years ago, was accurate. America has hard times ahead.
America is a democracy and has no Hitler, but I am afraid for her future; there are hard times ahead for the American people, troubles will be coming from within and without. America cannot smile away their Negro problem nor Hiroshima and Nagasaki. There are cosmic laws.

Pi Day, 2014

Happy Pi Day


Just wait till next year!

March 14 is chosen as the day to celebrate pi, because the numerical date, 3/14, represents the first 3 digits of pi. Hardcore Pi Day celebrants are planning special events for 9:26:53 a.m. on March 14, 2015, as the numerical date 3/14/15 9:26:53 represents the first 7 digits of pi, 3.141592653.


A Brief History of π from San Francisco's Exploratorium

Pi has been known for almost 4000 years—but even if we calculated the number of seconds in those 4000 years and calculated pi to that number of places, we would still only be approximating its actual value. Here’s a brief history of finding pi:

The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for pi, which is a closer approximation.

The Rhind Papyrus (ca.1650 BC) gives us insight into the mathematics of ancient Egypt. The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for pi.

The first calculation of pi was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world. Archimedes approximated the area of a circle by using the Pythagorean Theorem to find the areas of two regular polygons: the polygon inscribed within the circle and the polygon within which the circle was circumscribed. Since the actual area of the circle lies between the areas of the inscribed and circumscribed polygons, the areas of the polygons gave upper and lower bounds for the area of the circle. Archimedes knew that he had not found the value of pi but only an approximation within those limits. In this way, Archimedes showed that pi is between 3 1/7 and 3 10/71.

A similar approach was used by Zu Chongzhi (429–501), a brilliant Chinese mathematician and astronomer. Zu Chongzhi would not have been familiar with Archimedes’ method—but because his book has been lost, little is known of his work. He calculated the value of the ratio of the circumference of a circle to its diameter to be 355/113. To compute this accuracy for pi, he must have started with an inscribed regular 24,576-gon and performed lengthy calculations involving hundreds of square roots carried out to 9 decimal places.

Mathematicians began using the Greek letter π in the 1700s. Introduced by William Jones in 1706, use of the symbol was popularized by Leonhard Euler, who adopted it in 1737.

An Eighteenth century French mathematician named Georges Buffon devised a way to calculate pi based on probability. You can try it yourself at the Exploratorium's Pi Toss exhibit.

All who envision a more just, progressive and fair society cannot ignore the battle for our nation’s educational future. Principals fighting for better schools, teachers fighting for better classrooms, students fighting for greater opportunities, parents fighting for a future worthy of their child’s promise: their fight is our fight. We must all join in.

A Picture is Worth a Thousand Words - Mar.2013

Here are some pictures, graphic images and cartoons from around the net -- plus my own 2 cents worth of comments. Click on any image to see the full sized version.

Read Across America

March is Read Across America time. This year think about the wisdom of Dr. Seuss.



The Low Priority of America's Children

While the adults [sic] in congress fight over money nearly one-fourth of our children live in poverty.
"Recent research shows that many children who do not have enough to eat wind up with diminished capacity to understand and learn. Children don't have to be starving for this to happen. Even mild undernutrition - the kind most common among poor people in America - can do it." ~ Carl Sagan, Cornell University

"If a free society cannot help the many who are poor, it cannot save the few who are rich." ~ John F. Kennedy

"The test of the morality of a society is what it does for its children." ~ Dietrich Bonhoeffer

Aren't America's schools as important as America's banks, oil and gas companies, auto manufacturers...




Who Will Want to be a Teacher...

...if we continue to blame teachers for the failures of our society?

Many "reformers" claim to love teachers -- especially politicians right around election time -- yet they blame teachers and public schools for low achievement which is a product of the kind of economic system we've built. Teachers are the experts when it comes to education. Experience matters. Preparation matters.




Support the Arts in Public Schools

As cuts continue in public schools things like recess, the arts, and physical education are disappearing as well as science, civics, social studies, health. As the tests become the curriculum more and more essential activities are put on hold or eliminated altogether. Citizens need a well rounded education. Raising educated citizens needs to be a national priority...not test scores.
