“It took from a hundred to a hundred and fifty or two hundred years for the astronomy of Kepler to become the astronomy of Newton and Laplace], and for the mechanics of [[Galileo to become the mechanics of d'Alembert and Lagrange. On the other hand, less than a century has elapsed between the publication of Adam Smith’s work and the contributions of Cournot, Gossen, Jevons, and myself.”

— Léon Walras

“For two hundred and seventy-eight years after the death of Copernicus the church insisted that his system was false, and that the old Bible astronomy was true.”

Robert G. Ingersoll (1833–1899) Union United States Army officer

Orthodoxy (1884)
Context: In 1473 Copernicus was born. In 1543 his great work appeared. In 1616 the system of Copernicus was condemned by the pope, by the infallible Catholic Church, and the church was about as near right upon that subject as upon any other. The system of Copernicus was denounced. And how long do you suppose the church fought that? Let me tell you. It was revoked by Pius VII. in the year of grace 1821. For two hundred and seventy-eight years after the death of Copernicus the church insisted that his system was false, and that the old Bible astronomy was true.

“For two hundred and fifty years, from the second half of the eighteenth Century on, Capitalism was the dominant social reality. For the last Hundred years, Marxism was the dominant social ideology. Both are rapidly being superseded by a new and very different society. The new society – and it is already here – is a post-capitalist society… The center of gravity in the post-capitalist society – its structure, its social and economic dynamics, its social classes, and its social problems – is very different from the one that dominated the last two hundred and fifty years”

“It is only in the last five hundred years that music has become a spectator activity”

Daniel Levitin (1957) American psychologist

This is Your Brain on Music (2006)
Context: It is only in the last five hundred years that music has become a spectator activity—the thought of a musical concert in which a class of "experts" performed for an appreciative audience was virtually unkown throughout our history as a species. And it has only been in the last hundred years or so that the ties between musical sound and human movement have been minimized.

“There is one alternative to dark matter, and that is the assumption that Newton's laws don't hold over distances as great as galaxies. But we know that Newton's laws hold over a very large domain. And virtually one hundred percent of the physics and astronomy community believes that there is matter in the universe that does not radiate.”

Vera Rubin (1928–2016) American astronomer

“It took less than an hour to make the atoms, a few hundred million years to make the stars and planets, but five billion years to make man!”

“A hundred and fifty years proved the cure to be necessary but not sufficient.”

Barack Obama (1961) 44th President of the United States of America

2015, Commemoration of the 150th Anniversary of the 13th Amendment (December 2015)
Context: At its heart, the question of slavery was never simply about civil rights. It was about the meaning of America, the kind of country we wanted to be –- whether this nation might fulfill the call of its birth: “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights,” that among those are life and liberty and the pursuit of happiness. President Lincoln understood that if we were ever to fully realize that founding promise, it meant not just signing an Emancipation Proclamation, not just winning a war. It meant making the most powerful collective statement we can in our democracy: etching our values into our Constitution. He called it “a King’s cure for all the evils.” A hundred and fifty years proved the cure to be necessary but not sufficient. Progress proved halting, too often deferred. Newly freed slaves may have been liberated by the letter of the law, but their daily lives told another tale. They couldn’t vote. They couldn’t fill most occupations. They couldn’t protect themselves or their families from indignity or from violence. And so abolitionists and freedmen and women and radical Republicans kept cajoling and kept rabble-rousing, and within a few years of the war’s end at Appomattox, we passed two more amendments guaranteeing voting rights, birthright citizenship, equal protection under the law.
