I'm a Computer (Web) Programmer/Analyst based in Anchorage, AK and Minneapolis, MN. I use (among other things) ASP.NET, C# and SQL Server.

I build things. Bicycles, computers, websites, guitars, cars, motorcycles, sound sytems... lots of things.

P.S. if you can put that as an edit to your answer, perhaps with a synopsis of these comments, the bounty is yours.

Can you clarify how different that statement is from "Until proven otherwise, the Flying Spaghetti Monster created the universe from his noodly appendage", or any other faith statement? What else in science is 'true until debunked'?

Transfer heat from hot to hotter? Decrease the volume of the container. Cool matter? Increase the volume of the container. In both cases, heat is not 'transferred', but temperature (average kinetic energy) has been changed without the interaction of other matter, either hotter or colder.

So until proven false, the HUP is true?

In practice, I get this. I'm not claiming that we can make such a machine now, or soon. But the HUP seems to say such a machine cannot exist, now or ever, with more advanced races or technologies or anything. Are you saying an electron cannot be arrested completely - anywhere, ever, inside a black hole, at absolute zero - under no conditions ever?

comment Could we make a trebuchet that could launch objects to a stable orbit?
Thank you for that; I suspected #1. For #2, assuming that the object carried enough fuel to fix it's orbit: what would the trebuchet look like? How long of an arm / how much weight would be needed to get 100kg to 17k MPH? Is there a formula for the trebuchet design variables? It's poorly asked, I admit, but I want to know about the theoretical trebuchet more than the real world consequences.

Clarified that I meant into orbit, not escape velocity.

I rephrased question three, and clarified that I meant 'into an orbital velocity' from Earth's surface.

Why wouldn't it just invalidate it under certain conditions? For example: by some means, we completely arrest an electron. Position = center of device, momentum = 0. Both known simultaneously. Couldn't we just say QM is 'not a valid model for arrested particles but works for moving ones' without invalidating most of current physics?

Momentum = mass * velocity. We know the mass of electrons. We could get the velocity by tracking it's position. The 'Observer Effect' en.wikipedia.org/wiki/Observer_effect_(physics) takes into discusses destroying the system by measurement, but the HUP says nothing of the sort. The HUP is not about the observer, but says if a particle has a position, it DOES NOT HAVE A DEFINED MOMENTUM, and vice versa, regardless of my hypothetical measurement machine.

Sounds like a faith position to me. 'Accepting it as the most likely model of the limited amount of reality that we can observe' would be the more scientific approach rather than 'accept it as true, anything that contradicts it is de facto false.' The difference would be that in the former case, it's still up for discussion, the latter it isn't (which is what I observe to be the case).

I wouldn't need to measure spin, just position and momentum. Further, 'forcing' position AND momentum does fall under the HUP. The change in gravitational field is not necessarily an interaction with the particle - it's changing the gravitational field by some small amount as it rotates, and is influenced by the gravity of everything around it - none of this is considered 'interacting.' A machine that detects this minute change could conceivably exist sometime, but the HUP says it cannot exist.

I think you're making claims about the nature consciousness now that are unverified. Why can't I just observe you creating him, and he wakes up and starts observing me? Who cares? I don't even see how this relates to the HUP.

What happened to particle-wave duality? Is QM discarding the particle-side of this, and electrons are only waves now? How does a wave have mass?

Theoretical does NOT mean 'cannot be reached', just that it hasn't to our observation yet. The heliocentric model was theoretical until it was shown to be accurate. And no, you do not need colder matter to cool matter, you just need to cause energy to escape the matter to be cooled and concentrate somewhere else. You would just need the last bit of energy to escape the electron, so the electron stops rotating the nucleus.

Huh? I have no quarrel with randomness. And why wouldn't there be a 4th possible observation: you made a copy of me, that thought he was me, and we both coexisted? Why would one have to die or be teleported?

If the wave formulation is the right description, the claim is that if position is known absolutely, momentum is UNKNOWABLE and if momentum is known absolutely, position is UNKNOWABLE. I have no issue with randomness.
