With this term, the theory gave finite results; thus Tomonaga discovered the renormalization method independently of Julian Schwinger and calculated physical quantities such as the Lamb shift at the same time.
S tim pojmom, teorija je davala konačni rezultat; tako je Tomonaga, neovisno o Julianu Schwingeru, otkrio renormalizaciju i, istovremeno, izračunao fizikalne veličine poput Lambove promjene.
