Energy Quote by Steven Weinberg
“When you do calculations using quantum mechanics, even when you are calculating something perfectly sensible like the energy of an atomic state, you get an answer that is infinite. This means you are wrong - but how do you deal with that? Is there something wrong with the theory, or something wrong with the way you are doing the calculation?”

Quantum calculations often produce infinities, indicating a need for renormalization rather than a flaw in the theory.
In simple terms: Infinities show calculation issues, not theory failure.
Key Takeaway
Apply renormalization to handle infinities.
