A Total Solar Eclipse of Saros 145
A darkened sky holds bright planet Venus, the New Moon in silhouette, and the shimmering corona of the Sun in this image of a total solar eclipse. A composite of simultaneous telephoto and wide angle frames it was taken in the path of totality 18 years ago, August 11, 1999, near Kastamonu, Turkey. That particular solar eclipse is a member of Saros 145. Known historically from observations of the Moon's orbit, the Saros cycle predicts when the Sun, Earth, and Moon will return to the same geometry for a solar (or lunar) eclipse. The Saros has a period of 18 years, 11 and 1/3 days. Eclipses separated by one Saros period belong to the same numbered Saros series and are very similar. But the path of totality for consecutive solar eclipses in the same Saros shifts across the Earth because the planet rotates for an additional 8 hours during the cycle's fractional day. So the next solar eclipse of Saros 145 will also be a total eclipse, and the narrow path of totality will track coast to coast across the United States on August 21, 2017.

How Did Lenin Die?
The revolutionary Vladimir Lenin died at only 53 years old. But his death was a long time coming. He had lived with increasingly bad health for a while, including insomnia, increasing sensitivity to sound, and a series of strokes that left him progressively paralyzed. He considered suicide to escape, but no one would provide him with poison.
At the time, nobody knew what was wrong with him.
First Russian doctors suspected mental exhaustion. Then lead poisoning or metal oxidation, from bullet wounds he had received ten years earlier. Finally, they settled on syphilis because at that time everyone had syphilis. It was only after Lenin died in 1924, and they performed an autopsy that the true, horrifying cause of death was discovered. Vladimir Lenin’s brain had been slowly turning into stone.
The technical name for his condition was cerebrovascular atherosclerosis. It happens because calcium deposits built up in his cerebral arteries, to the point they became nearly solid, and blocked off nutrients to much of his brain. When the morticians tapped the affected areas with tweezers, they made a sound like stone. Unfortunately, cerebrovascular atherosclerosis is nearly untreatable even today.
Oração para livrar-se do mal
"Senhor Jesus, se algum mal me aconteceu, em minha alma, em meu corpo, em meu trabalho, em minha família, com vosso poder, por vossa misericórdia, por vossa vontade, fazei que eu, a partir desde momento, possa voltar a uma plena graça, a uma completa saúde, a uma perfeita união ao desejo da Santíssima Trindade. Eu vos peço, ó Jesus, por vossos méritos, por vosso sangue precioso, derramado na cruz, pelas dores da Virgem Maria e pela intercessão do patriarca São José, para a glória da Santíssima Trindade. Amém.”
