We were born in a state of grace, and all the seeking, all the personal growth and spiritual work that we do is directed toward finding our way back to that naïve vantage from which we once viewed the world.
We needed to acquire competence, but in learning to control and manipulate, we lost the power to regard the world as a wondrous miracle, our every perception a thing of profound beauty and infinite interest.

All will come again into its strength:
And no churches where God
The houses welcoming all who knock
No yearning for an afterlife, no looking beyond,

Rollo May, born this day in 1909, was a central figure in the movement for humanistic psychology. Freud made psychology a science by regarding his patients with clinical detachment; but May’s stance toward fellow humans was ever one of support and respect. His writings are inspirational because he reaches for the individual voice, yearning for expression within each of us. He liked to interpret common psychological maladies as conflicts between the society’s demand for collective conformity (so it can run smoothly) and the individual’s need for personal expression, the highest fulfillment of our beings. Always placing the individual first, he merged a radical social critique with a profoundly empathic view of humanity. His was a voice of wisdom.

Astronomers think that the greatest cataclysmic events in our galaxy produce gravity waves, but they're very hard to "see" because gravity is such a weak force. Gravity waves shake things up, like seismic waves only much, much less so. How do you look for a gravity wave? With a gravity wave telescope, of course.
Here's how to make a gravity wave telescope:
Now you've got a "laser-interferometric gravity-wave observatory", or LIGO.
"The changes in distance LIGO must detect are on the order of one one-hundred-millionth the diameter of a hydrogen atom, or 10 to the negative 21st power. That is the equivalent of the width of human hair in the distance between Earth and the closest star beyond our sun. The mirrors it uses are so flat, were any one blown up to the size of the entire United States, its minute wave-like imperfections would be less than an inch (centimeter) high. And the instrument is so sensitive, it can be thrown off by the motions in the ground and subsequent changes in its density and thus gravity caused by the tug of a wind-blown trees roots." (SPACE.com article)
How do you solve the problem of false signals? You build two such apparati, one in Louisiana and one 2,000 miles away in Washington State. If it's really a gravity wave, then the two should give coincident signals 1/100th of a second apart because 1/100th of a second is just how long it takes for gravity waves (or light, for that matter) to travel from Louisiana to Washington.
And what can you hope to see
with your gravity telescope? Only the most violent event in the
galaxy: the collision and merger
of two black holes. Here's a computer-simulated movie
of the event, just released to the public by the Goddard Space Flight center
