Mathematician Gladys West dies at 95. She was a hidden figure behind GPS. Without the mathematical model that she helped refine, “the extraordinary positioning, navigation, and timing accuracy of GPS would be impossible to achieve.”

Her research laid the groundwork for the Global Positioning System, GPS, a technology that has made getting lost a thing of the past.

Part of why I am insistent that public libraries must be expanded is because they can offer us a foundation for unleashing creativity and for nurturing imagination. This is an affirmative project at a time when we desperately need to be FOR things and not just against them.

A four panel comic. In panel 1, there are three beautiful blooming roses, and the text says "Roses are red..." In panel 2, there are some lovely violets budding and blooming, and the text says "Violets are blue..." In panel 3, there are some terrifying red and flesh colored plants with toothy maws and the text says "Hydnora are leafless, bizarrely fleshy, and incapable of producing chlorophyl..." and in panel 4 there are some cute hearts and the text says "And so are you. Happy Valentine's Day"

ICE to begin detaining immigrants inside Social Circle warehouse in April Homeland Security plans to build warehouse detention facilities in other cities being met with opposition.

ICE has now spent over half a BILLION dollars just on purchasing warehouses around the country to convert into detention camps.

If these mega-camps are utilized to the full capacity ICE intends, they'll be the largest prisons in the country, with little real oversight. www.ajc.com/politics/202...

It also points out how the cultural ignorance of much of our pundit & MSM class fails. 135 million Americans watched an important & controversial cultural event & many journalists are 1)ill-equipped to explain its significance or 2) too arrogant to know that would need assistance in unpacking it.

Asylum-seekers at the Center for Victims of Torture say ICE reminds them of what they escaped The torture rehabilitation clinic has pivoted to helping people process trauma from Operation Metro Surge.

Staff at the Center for Victims of Torture said that some conditions their clients face in the United States would qualify them for their services had they happened overseas. That includes clients who were recently detained by federal agents.

If you care about Don Lemon, don't forgot Mario Guevara (reporter who was filming police at a No Kings rally in June) was targeted for his journalistic activity; detained for 112 days; and deported. He had no criminal charges against him and was on the path to getting a green card.

“If (Taylor Rehmet) were to lose by six points, that’d be worth talking about,” one political expert told me ahead of last night's race. “And if Rehmet were to win? You’d say, ‘Holy shit.’”

Rehmet won by 14 points.
