Renormalization Theory Quotes & Sayings

The shell game that we play ... is technically called 'renormalization'. But no matter how clever the word, it is still what I would call a dippy process! Having to resort to such hocus-pocus has prevented us from proving that the theory of quantum electrodynamics is mathematically self-consistent. It's surprising that the theory still hasn't been proved self-consistent one way or the other by now; I suspect that renormalization is not mathematically legitimate. — Richard P. Feynman

Basically, my mother couldn't hold a tune and when I was a baby, a rather tactless baby, I would ask her not to sing ... you can't get to sleep if someone is singing off key nearby. — Vikram Seth

Wouldn't you like to weigh what it says on your driver's license? — Sam Ewing

But I have learned that you make your own happiness, that part of going for what you want means losing something else. And when the stakes are high, the losses can be that much greater. — Emily Giffin

Despite the experimental success of the theory...the fact that the infinities occur at all continues to produce grumbling...Dirac in particular always referred to renormalization as sweeping the infinities under the rug. I disagreed with Dirac and argued the point with him at conferences at Coral Gables and Lake Constance. Taking account of the difference between the bare charge and mass of the electron and their measured values is not merely a trick that is invented to get rid of infinities; it is something we would have to do even if everything was finite. There is nothing arbitrary or ad hoc about the procedure; it is simply a matter of correctly identifying what we are actually measuring. — Steven Weinberg

Renormalization is just a stop-gap procedure. There must be some fundamental change in our ideas, probably a change just as fundamental as the passage from Bohr's orbit theory to quantum mechanics. When you get a number turning out to be infinite which ought to be finite, you should admit that there is something wrong with your equations, and not hope that you can get a good theory just by doctoring up that number. — Paul Dirac

I don't have a Facebook or a Twitter account, and I don't know how I feel about this idea of, "Now, I'm eating dinner, and I want everyone to know that I'm having dinner at this time." or "I just mailed a letter and dropped off my kids." That, to me, is a very strange phenomenon. — Scarlett Johansson

In fact he was incurably insane and hallucinated more or less continuously, but by a remarkable stroke of lateral thinking his fellow wizards had reasoned that, in that case, the whole business could be sorted out if only they could find a formula that caused him to hallucinate that he was completely sane.*
*This is a very common hallucination, shared by most people. — Terry Pratchett
