Key Findings: 1) Off-grid solar microgrids are categorically faster than new grid interconnections (5+year queues) as well as off-grid colocated gas turbines (3+ year lead times).

I will tolerate recurrent laryngeal nerve slander no longer! It's actually the result of several elegant solutions to difficult problems in embryology, and the length is a non-issue. A 🧵 1/13

My meager education in biology and evolution gave me the mistaken impression that evolution optimized everything. But it didn't. One example is the recurrent laryngeal nerve (RLN). It goes from behind your ear, loops down below your aorta, and then back up to the voice-box 1/2

Yeah I’m “locked in”. I’m locked in a state penitentiary, eating free food, working out for free, building my network of hustlers for free.

That’s like saying “once we know about molecular dynamics, fluid mechanics no longer exists”. The second explanatory framework emerges via the computational irreducibility of the first.

The scary thing about a complete theory of physics is if you can predict the future perfectly then you no longer have free will.

For about a week, I’ve had a basketball floating in the pool and I’ve done nothing about it for obvious reasons. I can’t stop looking at it. Benefit > Cons

Every time I sit down and talk to someone, I begin the conversation asking them to speak at 1.25 to 1.5x speed. If they can't, I leave. I do not have time to waste.

This is bunk @BrianRoemmele. That 1960s Luna Orbiter image has all kinds of hairs and scratches on it (pictured). They don't appear in more recent imagery of the same location. Lat: 1.23 Lon: 76.16 #ufoX See for yourself: wms.lroc.asu.edu/lroc?projec…

Imagine using an ad blocker. Too scared to see products specifically catered to your liking. We live in a beautiful world surrounded by products and you’re trying to BLOCK THEM? Leave this weak mindset in 2023.
