A Celebration of Slavery

2016/08/29

(The Intercept) – Jon Schwarz:

Almost no one seems to be aware that even if the U.S. were a perfect country today it would be bizarre to expect African American players to stand for the Star Spangled Banner. Why? Because it literally celebrates the murder of African Americans.

Few people know this because we only ever sing the first verse. But read the end of the third verse and you’ll see why the Star Spangled Banner is not just a musical atrocity, it’s an intellectual and moral one, too:

No refuge could save the hireling and slave
From the terror of flight or the gloom of the grave,
And the star-spangled banner in triumph doth wave
O’er the land of the free and the home of the brave.

Venus and Jupiter Kiss This Weekend

2016/08/27

(Slate::Bad Astronomy) – Phil Plait:

There’s a real treat in the sky over the next few nights: Venus and Jupiter will be very close together. How close?

Very, very close. Closest approach (what astronomers call the appulse, but is more colloquially and commonly called a conjunction) will be on Saturday at 22:00 UTC (18:00 Eastern U.S. time), and at that time they’ll be an incredible four arc minutes apart. That’s only 1/15th the width of the full Moon on the sky! In fact Jupiter appears half an arc minute across, so Venus will only be about eight times Jupiter’s diameter away! …

The Clinton Foundation Is Not a Scandal

2016/08/26

(Slate::Outward) – Mark Joseph Stern:

The Clinton Foundation runs one of the most phenomenally successful AIDS relief programs of all time, and AIDS relief is simply not on most straight people’s radars. But let me provide a bit more background about the foundation’s work to provide a more complete picture of this purported “slush fund.” …
