@eric @kaia PowerShell is such a weird half-breed.

Went to see the TJ-II stellarator at CIEMAT. #physics #fusion

A social network where pixels of vertical space is limited rather than character count.

In my local supermarket there's a "clock" on the wall that seems entirely decorative. I think it's just a cardboard picture of a clock that always reads 4:45pm.

That got me thinking that non-functional clocks are a sign of civilisational decay. The object without its purpose.

Had a nightmare last night where I saw the blue criticality glow around something but couldn't find the emergency off button or open the shielding door. Then when it did open, the huge concrete rotating door nearly crushed me and a colleague.

As we left the turbopump going for a couple of weeks, the #vacuum chamber pressure is now 8.1e-10 torr.
There also appears to be a t^(-2/3) power law.

The stars are out and the humidity haze has cleared. Still all the leaves on the trees but at least I can see Cassiopeia now. #astronomy

@wolf480pl or "because we built it wrong"?

@wolf480pl My angle is amusement at all the blame-shifting. After 2001 it was always "the terrorists did it" and after 2010 "the social media did it".

It's funny how governments offer all sorts of theories on why riots happen, but "government policy" is never one of them.

Squinting at the ruler, I'm guessing the spacing of the T-slots on my driller machine is 45mm. I refuse to believe something made in China would use 1 3/4" spacing. 😀

The #vacuum group had connected the pumps and gauge this morning (gauge photo only shows backing vacuum level). The PC said "USB device detected: turbo pump" when we plugged it in! Then vacuum became e-7 level within 10 minutes of turbo operation.

"because using wood is lighter [than steel] you can build taller turbines with less material."

@splitshockvirus @eric @david It was still better than all the other integrated graphics options at the time. Intel integrated graphics from the early 2010s was a lot worse than a console.

@splitshockvirus I like the crusts but then again I am a duck.

Here's my other IPAC'24 poster about permanent magnets for the CEBAF energy upgrade. #physics #accelerators
