"Not a Number"
This is the second day in a row that Collin County, TX, has not reported or updated its COVID-19 case or death count (or any other statistics). It is – likely not coincidentally – two days since the State took over the handling of cases from the County. The question is: what is the state …

"Où est Lafayette?"
For want of a photo-op, the president ordered the forceful clearing of Lafayette Square last night ahead of curfew so he could awkwardly clutch a Bible and stand in front of a church. [1] Setting aside all the obvious things that are wrong with this (which have been well-covered in today’s commentary), I have been …

Really something to see the second stage engine glow red in the vacuum of space, a result of the heat dumped into the material causing the atoms in the material to emit radiation just in the visible human spectrum (red). That puts the temp at about 2000K. https://t.co/9MBGbTotuE2020-05-30T17:01:13Z via NavierStokes To: Public

From FAScientists on Twitter: FAS President Statement on American Withdrawal from World Health Organization @WHO - https://mailchi.mp/fas/statement-who-us-withdraw https://twitter.com/FAScientists/status/1266510923365261312/photo/1Legal authority for him to do so is 22 USC 290c. I’m not saying he is right or wrong. NPR had a rushed article out earlier swearing he lacked any legal authority.
We only withdrew from UNESCO twice in its history. There is unfortunate precedent for doing this to a U.N. system agency. We were about to inflict it on the Universal Postal Union too but that got stopped at the last minute.» Stephen Michael Kellat:
“Legal authority for him to do so is 22 USC 290c. I’m not saying he is right or wrong. NPR had a rushed article out earlier swearing he lacked any legal authority.
We only withdrew from UNESCO twice in its history. There is unfortunate precedent for doing this to a U.N. system agency. We were about to inflict it on the Universal Postal Union too but that got stopped at the last minute.”It gives authority, so long as 1 year notice is provided and this year's obligations are paid in full. There, the president appears to be in violation of the very same rule that provides the authority to withdraw.
And the FAS wasn't saying he lacked authority; simply, that they disagreed with the decision. They urged him to rethink the decision, one which he likely put not actual thought into in the first place given the madness of pulling out of a global health organization in the middle of a global pandemic.
