A Colourful Moon

The Moon is normally seen in subtle shades of grey. But small, measurable color differences have been greatly exaggerated in this mosaic of high-resolution images captured near the Moon's full phase, to construct a multicolored, central moonscape. The different colors are recognized to correspond to real differences in the mineral makeup of the lunar surface. Blue hues reveal titanium rich areas while more orange and purple colors show regions relatively poor in titanium and iron. The intriguing Sea of Vapors, or Mare Vaporum, is below center in the frame with the sweeping arc of the lunar Montes Apenninus (Apennine Mountains) above it. The dark floor of 83 kilometer diameter Archimedes crater within the Sea of Rains, or Mare Imbrium, is toward the top left. Near the gap at the top of the Apennine's arc is the Apollo 15 landing site. Calibrated by rock samples returned by the Apollo missions, similar multicolor images from spacecraft have been used to explore the Moon's global surface composition.

dietmountainmadewka: historical-nonfiction: Francis Scott Key,...



Francis Scott Key, the man who wrote the anthem of the United States of America, was a slaveowner with a complicated relationship with slavery. He publicly criticized cruelty to slaves. As a lawyer he represented several slaves seeking their freedom in court, and he took their cases for free. Key was also a founding member of the American Colonization Society, which aimed ease relations between blacks and whites in the United States by sending African-Americans to their own colony in Africa.

However, Key owned slaves. In fact he likely owned at least one slave when he wrote the Star-Spangled Banner. As a lawyer, Key also represented several masters seeking return of their runaway slaves. He left the American Colonization Society’s board in 1833 when it became more pro-abolition. And when Francis Scott Key became the U.S. Attorney, he used his position to suppress abolitionist publications and to prosecute abolitionists.

So in the end, despite moral qualms about the treatment of slaves, Francis Scott Key supported slavery and did what he could to maintain it.


I’m sorry, I feel like you might have missed the point of the post, @dietmountainmadewka. Francis Scott Key should be remembered as a complicated figure, who wrote our national anthem but who ultimately failed to consider fellow human beings …well, fellow human beings.

Chicago Was Home To The First Skyscraper, Although Its Arguable Which Building It Was!

The first skyscraper ever constructed was Chicago’s 13-story Tacoma Building, built in 1889. It was the first building supported by a riveted steel frame instead of by the walls of the structure. This is hallmark of modern skyscrapers through today.

Others argue that Chicago’s 10-story Home Insurance Company building, built in 1885, was the first skyscraper. It didn’t have a steel frame inside the building, but a fireproof metal skeleton outside the building.

Either way, Chicago gets to say the first skyscraper in the world was built in Chicago.
