FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.That is a consequence in certain situations of Bernoulli's equation. It is not Bernoulli's equation. -

Like.
Doesn't this come from the series being finite binary expansion? Being finite it will sum to a finite number. -
FactChecker replied to the thread Undergrad Computable sequence of rationals with a noncomputable limit.You should describe ##D## for us, I assume it is a subset of the natural numbers. With that in mind: Since ##f## is an injection on a...

FactChecker reacted to Ibix's post in the thread Undergrad Light clock treating horizontal and vertical motion differently? with Like.
I think it's also worth noting the existence of the so-called "one postulate" derivations of the Lorentz transforms, which only assume...

FactChecker replied to the thread Undergrad Light clock treating horizontal and vertical motion differently?.IMO, it is false that the Michelson-Morley experiments were artificially designed to give the result supporting the postulate of a...

FactChecker replied to the thread Undergrad Light clock treating horizontal and vertical motion differently?.Everything we believe boils down to acceptance of a set of postulates. In reality this may all be a dream of the Flying Spaghetti...

It isn’t relevant and it isn’t correct either. Some postulates are facts. Being a postulate doesn’t make something a fact, but it...

FactChecker reacted to Janus's post in the thread Undergrad Light clock treating horizontal and vertical motion differently? with Like.
While a postulate is not a fact, it we can make predictions as what would happen if it were true. This, in turn allows us to devise real...

Let's take that as your argument that physics generally is no good. So, what do we do? Get out the new-age crystals? Rely on ancient...

FactChecker replied to the thread Undergrad A variant of the Monty Hall problem.I would state this a little differently. Small changes in the host's behavior completely change our best guess of the outcome. In a...

Variants of the Monty Hall problem always mess with intuition at first. I remember thinking the probabilities should rebalance, but once...
