FactChecker replied to the thread Undergrad Transit time for a round trip to Alpha Centuri....At what point of their accelerated flight? They would have to explain why the distance got shorter than it originally was. My two... -

Informative.
That is incorrect. Also, the experiment shown is not the double slit with single photons, but a double slit experiment done with a light... -

Informative.
You can't maintain a Minkowski coordinate acceleration of 1g for more than a year(ish) anyway, even in principle, since you'd reach... -

Yeah, ##a## is proper acceleration here. -
FactChecker replied to the thread Undergrad Transit time for a round trip to Alpha Centuri....I assume the acceleration here is measured in the spaceship time and distance, since the OP wants it to feel like Earth's 1g to the... -
FactChecker replied to the thread Graduate Evolute of an Evolute... ad infinitum?.By "halt", do you mean "converge to some finite geometric shape"? I would bet anything that those are very special cases. It might be... -
FactChecker replied to the thread Graduate Request for References.After reviewing the implicit function theorem, I see that your statement fairly closely follows it. I don't think you need any specific... -
FactChecker replied to the thread Graduate Request for References.Then I would just say it follows from the implicit function theorem and leave it at that. -
FactChecker replied to the thread Graduate Request for References.Honestly, I am having a hard time simply understanding the statement of your theorem, let alone know where it can be referenced as... -

Well this makes sense to me since the government is largely responsible for and leading the way on these issues. If I wanted a better... -
FactChecker replied to the thread How good is Brian Cox as a science communicator?.If their "pronouncements" are just relaying the best knowledge of experts in the field, is that OK? If so, they should just make it... -

One of the things that sparks public skepticism is when scientists with expertise in one area use their authority to make pronouncements... -
FactChecker replied to the thread How good is Brian Cox as a science communicator?.I disagree. Mathematics is based on logic derived solidly from the axioms and stated assumptions. The logic is not "bent" to fit... -

i.e. when we have found a working model We really don't need an apologist for Maths but, as it's based on axioms, it doesn't need... -
FactChecker replied to the thread How good is Brian Cox as a science communicator?.If you have any counterexamples to the accepted mathematical axioms, please let us know. Pure math is pure until it is used; then it is...
