We know that 22 means 2⋅2, 23 means 2⋅2⋅2, and 25 means 2⋅2⋅2⋅2⋅2 and so on and so forth. But what does 22.5 mean? I don't mean to say "How to find it out". I mean, what is the idea behind it? Is it something like "If S=V⋅T, then T=SV and T gets smaller as V gets bigger, and theoretically V can get so big that T might become 0. (that is, lim" but can't be shown physically?
