The paper then discusses trial-and-error approaches and self-organization effects within every nanodesign procedure, and considers the impossibility of forming perfect nanoproducts.
These preliminary evaluations force to consider the impossibility to preserve the necessary overpressure and the shape geometry without any refill of gas.
I never ever considered the impossibility of the story I was told this by my parents, and I guess, on some level, I didn't want to question it.
As a criterion for exclusion, we considered the impossibility of obtaining clinical information for individual patients.
Evidently, the number of size classes of protein families, N, should be finite, although intrinsic features that could determine the value of N so far have not been considered (the impossibility of an infinite genome is self-evident but one would expect a much tighter bound based, e.g., on the limited time and resources available for genome replication and expression).
This paper considers the impossibilities, uncertainties and undefined relationships that may be involved in extending scientific and humanistic interest towards the development of nanosciences and nanotechnologies.
Or consider the famous "impossibility theorem," developed by the economist Kenneth Arrow, which shows that no single voting system can simultaneously satisfy several important principles of fairness.
Booth says that to achieve this effect with no computer assistance whatsoever would have required 8,640 cameras (one for each frame of the six-minute video) — a physical impossibility, considering the splash is about the size of a quarter.
Even if a manual recount is performed flawlessly (an impossibility considering the charged atmosphere under which such recounts occur), the mark made by a voter may not be counted because the states have developed different and obscure criteria for what constitutes a valid optical vote.
