Like.
@PeterDonis @Matterwave They state that the systems interact until T, “[...] let us suppose that we have two systems, I and II, which... -

Are you reading the EPR paper? It was an implicit assumption of EPR that sufficient spatial separation implies non-interaction. They...

Dale reacted to oracle99's post in the thread Undergrad Transit time for a round trip to Alpha Centuri... with Like.
Just a simple little question as my first post here.. Suppose you have a space craft that has an engine that can exert an acceleration...

That's rather Zen, and is more pertinent to the question than jokes that depend on language, like puns and idioms. I recall this one...

Dale replied to the thread Jokes and a language: how does it work?.I guess there are several different types of humor, some of which will translate and some will not. Puns probably don’t translate, but...

Dale reacted to PAUL GRAHAM's post in the thread Undergrad Compare Bending Resistance of Dimension Lumber used as Joist with Like.
Thanks to all you guys for your input on my project. This started out one way and went somewhere else. It's a better solution than the...

berkeman, et al : Here is the design using plywood. Do I have this right? One thing I would be inclined to do, but not shown here...

Dale reacted to Matterwave's post in the thread Graduate How valid is the indivisible interpretation of quantum mechanics? with Like.
Very noob question, and totally understand if the answer is "go read the paper", but to what level of detail has this "interpretation"...

Dale replied to the thread High School What Medium Does Light Travel Through in Space?.If the rule is personal preference then my personal preference is simply to acknowledge that the quantities have different dimensions in...

Oh my goodness! What a mess! :-) I guess all quantities had to change to accommodate the ##k##. Yes, such scenarios are also possible...

Dale replied to the thread High School What Medium Does Light Travel Through in Space?.Yes, it is dimensionless in SI units, but not in imperial units. In imperial units it is ##0.031 \mathrm{\ lbf \ s^2 \ lbm^{-1} \...

Dale replied to the thread My physics exam preparations feel like rote actions, I'm not understanding.It seems to me that the rest follows from this.

They can in principle, but they were not in any experiment done to date. And we see no reason for them to be broken. What's your point...

Sad.
a decade or so allegdly physicists found a neutrino with a speed faster than the speed of light. After a few weeks they found a mistake... -

Given the abundance of empirical evidence for finite light-speed, what does this statement even mean?
