The fact that SpaceX has been extremely operationally active with orbital work since 2008 I think while Blue Origin still has yet to launch an orbital rocket speaks volumes, along with the fact that the Blue Origin proposal was twice as expensive as SpaceX.

Combine with NASA having their HLS budget literally quartered by Congress… Obviously spend it all on the company with a proven track record and don’t dilute for the sake of redundancy.

That redundancy after all got NASA real far with the crewed space flight program. Boeing got way more money, and still hasn’t completed even an…


Entanglement is simply the idea that quantum processes are correlated. Therefore you can infer things like intrusion more or less instantly.

A good example I’ve heard is that it’s like having a pair of black socks. You realize you accidentally put on only one of them, and instantly know that the other sock must be back at home.

But the socks didn’t talk to each other or anything. No fundamental communication between two parties can occur. (Certainly no “teleportation” in the way we think of it occurred.) You can see by deconstructing a little bit. How do we coordinate, for…


First, to be clear to newcomers: I am very much to the left side of the political spectrum — but I dislike disregarding the practical side of things. Passion and pragmatism are like a compass and a map; you need both to get where you’re going. I’m the kind of person who’s been masking and double-masking for most of every day for the last year and change. I speak from a personally informed perspective, and certainly not from anyone’s talking points let alone the right-wing. I articulate genuine concerns here.

As vaccine usage increases, we need to be more careful…


Trying to match the old man since day 1 apparently

A year ago today, I lost my dad.

They let us into the hospital to see him so long as we “followed CDC guidelines” on the pandemic, which is to say doing what is now common and everyday. I’m acutely aware that many others suffering losses of their own during this time didn’t get the same privilege of access. I don’t fully understand why there was an exception for my family but I am grateful for it.

Security gave me along with the others a green wrist band, the paper kind like you’d get at a concert, to control admissions…


The point of “wokeness” is not to feel sorry for being white.

The point is to realize race is not biological but was essentially created to delineate who has power and who serves that power: white and Black respectively in America. The first significant comments on substantial differences between white and Black people came from white people in power.

The people who held and who still benefit from that racial-based power, white people, do not get to suddenly switch over to a color-blind reality, specifically now that it’s become inconvenient and Black people are pointing out how they, for example…


It’s worth saying that as a space exploration enthusiast and advocate, it’s encouraging that the senate committee hearing for Biden’s choice for NASA administrator earlier today focused so much on continuity with the actions and decisions initiated by Jim Bridenstine, and more indirectly Mike Pence, particularly on the moonshot Artemis program.

As a loyal Seattleite, I’m supposed to side with Senator Cantwell’s objection on the exclusion of Blue Origin in NASA’s recent controversial and frankly unusually aggressive decision to pick SpaceX for the first round of funding for a new moon lander at the exclusion of any backup redundancy option.


OC — except for Nikola himself, because he’s the only true OC

Look… Tesla was a very talented electrical engineer for his time. That’s all.

Now, “that’s all” isn’t nothing, because electrical engineering has always been very hard for everyone, and so making anyone successful in it is impressive let alone someone very talented. But it’s not everything, either. In particular, Tesla wasn’t exactly a groundbreaking theoretical physicist in disguise or anything.

The easiest critique to resort to with Tesla’s achievements and lack thereof concerns his attacks on special relativity. This is most famously associated with Einstein (which in turn invites the too-easy rant in response, “Well are you saying Tesla was…


Okay, so what’s in there?

$620 billion on roads, bridges, electric vehicles, public transit, seaports, airports, etc.

$300 billion on medical and technological manufacturing, $100 billion in internet infrastructure particularly for rural areas, and $180 billion in national R&D.

$100 billion for clean water nationwide via piping improvements, and $200 billion for the home legal and construction apparetus.

$110 billion for schools, including “better ventilation systems, updated technology labs, and improved school kitchens that can prepare more nutritious meals.”

$30 billion for improving VA hospitals and modernizing federal buildings.

And yes, also $400 billion in elderly caregiving, because we don’t…


A political post, except nothing here should be a function of personal politics.

It’s been in the news recently how Army Lieutenant Nazario of the Virginia National Guard is suing a local police department for $1 million of allegations of assault. This situation has begun obsessing me, as it is increasingly outrageous the more the details are unearthed and people defend them.

When the original officer starts flashing lights and sirens for him to pull over, the lieuteant immediately slows down (20–35 mph on a highway, depending on source) and signals to move over. …


If it weren’t for the people who saved the world from what might have been, the world would never know what would have happened. And even if they did, they wouldn’t care. No one cares about the bomb that doesn’t go off. Only the one that did. It’s the bomb that didn’t go off, the danger no one knew was real… That’s the bomb with the real power to change the world.

Tenet by Christopher Nolan gets better every time I watch it, in a meaningful way. There’s a sly Feynman reference interlacing it throughout that I only just realized…

This effort has evolved to primarily be for clearly communicating technical subject matter to the public: largely my two passions astrophysics and space travel.
