Random is when you give up looking for a pattern (at least for now). Chaos has patterns but it’s highly dependent upon initial conditions and can change as it progresses (“it” being what’s being measured). Manage

Here, the switch (“any”) position is realized in entangled form. This will be fantastic for nano scope engineering projects. “Quantum mechanics allows events to happen with no definite causal order: this can be verified by measuring a causal witness, in the same way that an entanglement witness verifies entanglement. Here we realise a photonic quantum switch, where two operations, ^A and ^B, act in a quantum superposition of their two possible orders. The operations are on the transverse spatial mode of the photons; polarisation coherently controls their order. Our implementation ensures that the operations cannot be distinguished by spatial or temporal position—further it allows qudit encoding in the target. We confirm our quantum switch has no definite causal order by constructing a causal witness and measuring its value to be 18 standard deviations beyond the definite-order bound.”
So in short, they … [read full article]
Oh I have everything but it’s scattered. I’m always “in the present moment”, which is a window going back about 3 days and ahead 3 days with now in the middle. Like a bead on a string, I slide forward in time and leave a mess behind me.

It’s a mush. STEM (Science Technology Engineering Math) as one ‘thing’ is a terrible idea. There is MUCH that’s not the same between them. They CAN support each other and it’s great that they can, but it’s important they retain separate identities.

Coin flips are wholly independent operations though, aren’t they? The “or” is not provided by the machine.

This is where it gets interesting for me: The stickiness of “nothing” is an actual manufacturing problem. It was a problem with electrostatics since the early days of electricity and remains an issue as manufacturing gets deeper and deeper towards a bottom that might not even be there.

The world is full of ambitious people who have the drive but not the resources. I know I could’ve had a PhD or two under my belt but couldn’t even afford to get an Associate’s degree. (2 complete years). In the USA, you have a SMALL window of help: Age 18-23, approximately. After that, help dries up and life moves on. Gotta work. Had your chance, etc. I don’t regret it because the US is a class based system, mostly hinging on family community status and provable family income. Even with assistance, if your family couldn’t have afforded tuition, it also means you won’t be able to afford to avail yourself of opportunities that come only to those with sufficient connection and family (not personal) income. I didn’t have that and it’s ok. I like my life and glad for the choices I made out of what was available and my capabilities and drive. But I feel for those who DO want more, strive for it, have the intelligence but get little of the assistance (for lack of family community status and family income). If you pry behind the stories of the “self made successes”, you’ll usually find big helpers along the way that “lift” them up and continue to, often political in some way.
