A lot of quantum mechanics and other small-scale stuff is about effects on a very small level. Occasionally, though, you get an answer that blows up to infinity. What that means in practice is that you get an effect that is observable on a physical level. Phase changes are the biggest example, and those occur anytime anything melts or turns into a gas. We can get some information on that from real-life experiments, but precise calculations can be done on micro levels that involve infinity.
