There is no 'this sentence' for "This sentence" to refer to at the instant when it is spoken, heard, written or read. Speaking, hearing, writing and reading "This sentence is false" takes time, even it only a second or two. So at the instant "This sentence" is spoken, heard, written or read, there is no sentence for "This sentence" to refer to. So if no ...

No, there is not really a connection here.
You have to be careful: natural-language sentences generally aren't even expressible in a given formal framework, and even when they are they don't necessarily behave as expected.
For example - assuming we're looking at classical first-order logic - the sentence "This statement is false" is never expressible in ...

Whilst some said it is resolved like Russell by defining clearly the concept of motion as over time, it really does not. The problem is that even if you accept motion over time, the Achilles vs tortoise still there. Yes but a and t move over time. But by taking snapshot infinity small in time a can never take t. Even worst qm has a quantum Zeno effect about ...
